How to Charge your S4 Battery and Keep it Working Longer
There are many myths surrounding batteries, charging them, and keeping them charged.
If you are using your Samsung Galaxy S4 for the first time, you've probably been told that you're required to fully charge it, and then fully discharge it, with a strange list of other steps that you could easily mistake for some bizarre form of battery voodoo. Fortunately, you can ignore most of what you've been told, and even most of what you know from the older generation of NiCad batteries you're probably accustomed to.
- For reference, purposes, NiCad is short for Nickel Cadmium batteries, and they are what you've probably been using in any phone you've owned previously. They do require 'training', and need to be used a particular way to help prolong their effective life.
Your Galaxy S4 is different. It uses the latest battery technology, which is Lithium-Ion, or Li-ion. These batteries thrive in environments of burst use, where your device is never fully discharged, and is fully charged every day or so. In fact, it's best to charge them at around 25% or so battery life, which is what most people do already. However, unlike NiCad batteries, your GS4 battery should never be fully discharged unless it's incorrectly reporting the battery status. We'll discuss that in more detail later.
It is very important to fully charge your GS4 battery before using it for the first time.
Most people do this overnight, while they sleep, however, you can chose to do it in whatever manner is most convenient of for you. Just make sure to use the supplied charger if possible. This will charge your device more quickly than using a USB cable to charge it. Also, it's not necessary to unplug your phone the second it is fully charged. The S4 is a smart phone, in that it will stop charging once the battery is fully charged. Therefore, unless your device is defective, it's not possible to 'overcharge' it.
It is impossible to 'overcharge' a functional Samsung GS4, because the phone stops charging when full, and even if that fails, the battery also stops charging when it is full.
For reference, the factory standard battery status icons for the Samsung Galaxy S4 display either charging, or fully charged states. Charging is represented by a series of five circles, with a partially full battery (shown in the left image below). Fully charged is shown as a 100% full green battery (shown in the right image below).
How to Charge your S4 Using the Factory Supplied Charger
This is the fastest way to charge your phone.
Using the supplied USB Power Adapter, the first time you fully charge can take from a few minutes to a a few hours, but usually takes two to three hours. Below you'll find the standard steps for charging your Samsung with the USB Power Adapter charger:
- 1Connect the USB cable to the USB Power Adapter.Advertisement
- 3Plug your charger into the power supply socket.
- 4Wait for your phone to be fully charged, indicated by a continuously lit green LED.
- 5Unplug the cable from your Samsung Galaxy S4.
- 6Unplug your charger from the power supply socket. Alternatively you may leave it plugged in if it's in a convenient location, where you'll regularly be charging your phone.
How to Charge the Galaxy S4 Using a Computer or Laptop
USB makes this possible.
One of the advantages the Galaxy's USB connection port provides is the ability to use any USB enabled device to charge your phone. However, due to the lower power output of a USB port, this method does take longer to charge your phone. Here are the steps to charge your phone using your computer or Laptop.
- 2Plug the other end of the USB Cable into any USB port on your computer.
- 3Wait for your phone to be 'fully charged.' (It will notify you.)
- 4Unplug the USB cable from your Samsung Galaxy S4.
- 5Unplug the USB cable from the computer's USB port.
- 6That's it. You've successfully charged your GS4 using the USB port of your computer.
- Did you know that you can also use USB devices like your PlayStation to charge your Galaxy S4? Just plug it into one of the spare controller slots, and it should charge - just like your controllers do.
How to Charge your Galaxy S4 in a Car, Truck, or Boat
Your car needs to have a cigarette lighter outlet for this to work.
A holdover from a bygone era, the cigarette lighter outlet in cars and trucks has remained relatively unchanged for longer than almost any other electrical component in one. Anywhere in the world, cars still have these, but they've transformed from lighting cigarettes to powering and recharging electronics. So, if you're on the road a lot, or planning a road trip, you can easily recharge your Galaxy S4 with a car charger, which costs less than $10 from Samsung.
If you're in a boat, or on a motorcycle, you can purchase a special boat and motorcycle charger for your Galaxy S4, for about $5 or so. The installation is simple, and requires very little in the way of tools or expertise.
Whatever you choose, you'll want to follow these simple steps to charge your Galaxy S4 in a car:
- 1Plug the 'round' end of the charger into your cigarette receptacle.
- 2Connect the retractable cord's mini jack into the mini jack of your Galaxy S4.
- 3Once charged the battery icon on your Galaxy will have a full and continuous green light.
- 4Unplug the retractable cord first from your Samsung Galaxy S4.
- 5Then unplug it from your cigarette lighter receptacle.
- 6Congratulations, now you know how to charge your S4 on the road.
- The charger you get is entirely up to you. You might prefer one with other features, such as the retractable car charger, like we've shown in the photo below.
How to Keep Your S4 Battery Performing its Best
Li-ion batteries are pretty smart, as batteries go.
To give your Li-ion battery the longest life possible, there are a few simple steps you should follow.
- 1Fully charge your battery when you first start using your phone. If you just got a new battery, fully charge it just like you would if it was a new phone.
- 2Make sure to recharge your battery before it goes below 15% charge. Recharging at 25% charge level is ideal.
- 3Do not expose your battery to heat. This is especially true of leaving it in the sun, or in a car, as the inside of your car can get hot enough in the summer to damage the battery, or even cause it to explode.
- 4Avoid fully discharging your battery to the 0% state. The only time you should ever discharge your battery to a 0% state is when it is not correctly reporting. An example of this is when your battery seems to randomly lose charge, or drop to zero. In such cases, let your phone fully discharge (0%), and then fully recharge it.
How to Increase Battery Life on the Samsung Galaxy S4
If you want to get more time from each charge, try this.
If you're finding that your battery doesn't last as long as you thought it would, here are some tips to help you squeeze every last bit of life from it.
- 1Close all unnecessary applications when they are not in use. Use your task manager to view all active applications, and close the ones you aren't using.
- 2Deactivate Bluetooth when not in use.
- 3Deactivate WiFi when not in use.
- 4Switch your device to 'Sleep Mode' when it is not in use. Auto-sleep may be turned on, but you can save even more power by pressing the Power Button once (which puts the phone in sleep mode) when you are not using your phone.
- 5Deactivate 'Auto-Syncing of applications.'
- 6Decrease the Backlight Time of your device.
- 7Decrease the display brightness.
- 8Turn off vibrate, and only use ring.
- 9Turn off your camera flash when not needed.
How to Tell How Long it Takes to Charge a Galaxy S4
Charge times vary depending on the method.
Normal charge times for the Samsung GS4 vary depending on whether you're using the wall charger, a USB charger, or a third party device. While there are some cool third party devices out there, some of them, like the Levin Solar Charger, can take a day or more to charge a device - but aren't intended as a substitute charger. Because of that, we'll just discuss the two most common forms of charging - USB and Wall Charger.
- 1Galaxy S4 Charging Time Using the Samsung Wall Charger:
- Wall chargers are capable of delivering outputs ranging from 0.5A to 2.1A. The Galaxy S4 stock charger comes with 2A amperage. In theory, a totally dried out 2,600 mAH battery should be able to load up in less than 2 hours using a 2A charger.
- In practice, the Galaxy S4 uses Lithium-ion batteries, and because of the proprietary mechanisms that promote battery longevity, the charging time may be longer.
- 2Galaxy S4 Charging Time Using a PC USB Port:
- A computer's USB 2.0 port usually outputs 0.5A. This means that a Galaxy S4 phone will in most cases charge significantly slower than it would on a stock Samsung wall charger.
- A computer's USB 3.0 port usually outputs 0.9A. This represents an 80% increase in speed over a USB 2.0 port, meaning your phone will charge almost twice as fast.
- It's important to keep in mind that different USB cables will also impact this process. Low priced USB cables are usually poorly shielded, and will 'leak' current, resulting in a much slower charging process.
- 3Samsung Galaxy S4 battery statistics and facts:
- The battery is listed at 2,600 mAH (milliamps/hour)
- The charger and the handset undergo a process called 'negotiation' where the amount of power transmitted between the charger and the phone is defined. There is no universal standard for this negotiation process, so it is subject to proprietary preferences.
- The Galaxy S4 only takes the current it needs, and nothing more. This means that even if a charger is capable of delivering a maximum current of 2A, it will still depend on the result of the negotiation process at to how much actual current the phone will draw from the charger.
- Lithium ion battery powered phones usually employ a mechanism that slows down the charging rate as the battery approaches its full capacity. This is done for battery longevity purposes.
- 4Bypassing the Galaxy S4 charge negotiation limitations:
- One interesting device is the Practical Meter, which identifies the actual current being transmitted to your phone while charging. This lets you know approximately how long until your devices is fully charged.
- More importantly, it has the ability to override the 'negotiating' process between the USB port of the power source and the Galaxy S4, allowing the maximum charge speeds to be attained.
GS4 Battery Myths: True or False
Your Li-ion battery uses the latest technology - and requires special care.
The science of batteries has nothing to do with myth, yet due to the amount of time battery technology has been in use, there are certain things that people have come to believe about them that aren't necessarily true or accurate. This because, as technology changes, so do the best practices for prolonging the serviceable lifespan of that technology. Batteries are no different, and your Samsung Galaxy S4 uses the latest Li-ion technology, which is quite different that it's predecessor, the NiCad battery.
Read on to learn the difference between fact and fiction.
- 1You should wait until your battery is fully discharged, or at 0%, before recharging it - FALSE. Your Li-ion battery uses a new technology, and fully discharging it can actually hurt the lifespan of your battery. Do not wait until it is fully discharged or at zero percent. You should actually charge your battery when it is at 25%, or at a low of 15%.
- 2If your battery is almost at 100%, you should unplug the charger to avoid overcharging the battery - FALSE. Your Samsung Galaxy S4 will automatically stop charging your battery when it reaches 100% charge. In the event this system were to fail, your Samsung brand battery is also equipped with an internal mechanism to stop charging when it reaches 100%. Combined, these two failsafe prevent any chance of overcharging.
- 3It is best to charge your phone when you are awake so that you can keep track of when it is fully charged - FALSE. See number two, above.
- 4Overcharging can harm your battery - TRUE. Overcharging your battery can cause it to explode, however, there are two failsafe mechanisms in place on the GS4 to prevent overcharging. Therefore, your phone will automatically stop charging when it is full, and your battery will not accept additional charge, even if your phone did not stop attempting to charge it. That said, should you bypass these safety features and intentionally overcharge your battery, it can explode.
- 5If you have to charge your battery you can do it even if it is still on a high percentage, and this will not harm the battery - TRUE. It is always best to keep your battery charged whenever possible, so as to avoid fully depleting your charge.
- 6Charging your battery daily can lengthen its life - FALSE. Lithium Ion batteries have a set lifespan. Charge as needed, because charging your battery more or less will not change the lifespan of it.
- 7You can fully drain the battery once a month to calibrate the battery - FALSE. This is true of NiCad batteries, however, it DOES NOT apply to Li-ion batteries.
- 8Avoid overheating when charging the battery - TRUE. You should avoid excessive heat with your Li-ion battery, as this can damage the battery.
- 9Make sure there is good ventilation in the room where you charge your phone - FALSE. Li-ion batteries are closed, and do not release gases when charging or discharging. You do not need to ventilate your phone.
Tips and Suggestions on the GS4 Battery, and Charging it
- Use only original standard Samsung charger, batteries, cables and adapters. Using nonstandard accessories may cause damage to your phone, or void your warranty.
- When your phone display of battery charge drops below 15%, charge your phone as soon as possible.
- To speed up the charging process, close all running applications and wireless connections (WiFi, Bluetooth, SBeam) during charging.
- Make sure to connect your charger properly. An improperly connected charger will result in less receive charge, and can significantly increase resistance based heat, ultimately damaging your phone. Should damage from this happen, it will usually not be covered under warranty, as views this as damage due to negligence and misuse.
- While charging your phone, if the main power supply becomes unstable, your touchscreen may not function. Remove your charger from the main power supply, and wait until the main power supply is stable once again. You can also use an AVR (Automated Voltage Regulator) to stabilize your electric current.
- Situations where this may occur are any instance where you are using dirty power to charge, such as that from a generator, or in situations where your local or regional power supply is degraded. While not as common in America and Canada, it is a common problem in other parts of the world, and one users should be aware of.
Questions and Answers on S4 Battery Life and Use
Does charging a battery before it is depleted cause damage?
charging a battery before it is depleted cannot cause damage to your mobile phone
Actually, one of the things that causes the battery damaged is going all the way to zero battery depletion. It is suggested not allow it to get to zero, as it can degrade the battery's life, especially if you have a lithium ion battery. Lithium ion is used for Samsung Galaxy S4 mobile phones. You should also be aware that there are different types of batteries used for various mobile phones:
- Lithium polymer batteries (Li-Poly)
- Nickel metal hybrid batteries (NiMH)
- Nickel cadmium batteries (NiCd)
- Lithium ion batteries (Li-Ion)
Lithium ion is the most popular, expensive, and current technology for mobile phone batteries. There are drawbacks, of course. Apart from degrading the battery's life, it can also cause damage when it is overcharged for up to 24 hours. Additionally, it can explode if it is charged when completely drained. Why is this so? Lithium ion batteries have self-destruct circuits, which will disable the battery permanently, if they reach rock bottom.
So this is actually better than charging the battery when it is completely empty. Leave 40 percent of battery life and you can recharge it.
Yes, over a period of time it can cause damage to your device. It is recommended that you allow your battery to fully die or discharge before charging it back up fully.
Can Samsung S4 use a normal mini USB cable, or does the S4 require a special cable for charging?
Do I need a special cable to charge my phone?
No. Unlike Apple, Samsung does not natively limit its devices with proprietary hardware or software restrictions. Therefore, a standard mini USB cable will work for charging or data transfer purposes. The brand of the manufacturer of the USB cable you choose to use does not matter. However, low-quality cables are often poorly shielded, and will not perform at the same level as a higher quality component.
How long does it take my Galaxy S4 to charge?
What is the charge time from empty to full for my phone?
The normal charging time of Galaxy S4 is not definite and varies according to a number of factors discussed previously in this guide. In theory, your device should completely charge in about two hours. However, some methods are noticeably slower than others, such as USB 2.0 versus the Samsung supplied wall charger.
The Practical Meter discussed earlier in this guide, is a third party charging tool that can improve charging speeds of your Galaxy S4, or any other device you choose to use it with.
See more questions like this: Why does my phone says "charging paused, battery temperature too low?"
Do I need to charge my S4 before using for first time?
Is it OK to use my new phone if I did not charge it?
The battery that comes with your Samsung Galaxy S4 is already pre-charged, so you can use it out of the box, however, you should plug it into a charger while you are using it, so that you fully charge the battery. Manufacturer recommendations are that you fully charge it before first using it - however, most people generally set up their phone while it is charging, and many stores will set up your phone in the store, before it has been fully charged.
How often should I charge the battery of my Samsung Galaxy S4?
Can I charge my GS4 every day?
The Samsung Galaxy S4 makes use of a Lithium Ion or Li-ion battery and should be charged as needed. Ideally, you should not let it drain below 15% charge too often, the higher percentage the battery discharges, the shorter lifespan it will have.
Why is my Samsung Galaxy phone taking longer to charge than before?
For the first 3 months, it took two hours for my S4 to be fully charged. Now it takes three to four hours to fully charge. Is this normal?
No this is not normal. There are two possible causes.
- 1A Battery Draining Application: You may have installed a battery draining app or widget. When your phone is being charged, the app is still running in the background and consuming power. This can cause your battery to take longer to charge. Android and Samsung Apps don't go through the stringent power testing that iPhone Apps do, so it is possible that you could have an App draining your battery. This is especially true if your phone is draining the battery even when it is screen locked, and should technically be 'OFF', because some of these Apps can run constantly.
- 2A Bad or Defective Battery: It is also possible that you have a bad battery. Note that with a battery, past performance is no indication of future performance. Your battery can go bad at any time, and either gradually, or all at once. Sometimes it is due to the natural progression of a battery through its lifespan, and other times it can be caused by dropping the phone, or a particular defect that wasn't apparent earlier in the lifespan of your battery. This is because batteries are made up of several small cells joined together. If one or more of those cells goes bad, the battery will still produce the same voltage, but the amps (output power) are reduced. This is why you experience diminished battery life. In this case, the charging time is particularly affected by one or more bad cells, as they often drain or hampers the charging of any remaining good cells.
- Note that you can usually get inexpensive Lithium Ion batteries on eBay from China. Some of our users have reported ordering replacements, and even upgrading batteries with a higher amperage than their original Samsung phone battery. Having a spare battery is a good idea anyway, but pay attention to any requirements of the Manufacturer's Warranty.
How long is the charging time of Samsung Galaxy S4
As mentioned on the preceding question above, there are some factors that can affect the charging time of your Samsung Galaxy S4. Using the supplied charger, charging your Samsung Galaxy S4 from 50% to full would normally take about 2-3 hours. The following factors will affect the charging time of your Samsung Galaxy S4:
- 1Battery condition. Your battery health is a huge factor in determining the charging time of your Galaxy S4. A battery in good condition will have the normal charging time. A battery on bad health will have a lower charging time. However, do not let this fool you. Lower charging time for a defective battery means that it will also take it faster to lose battery juice. This is because a defective battery will only hold less juice than a healthy battery. Thus, it may appear that your phone is fully charged in a short time when the truth is, battery capacity had just been lessen.
- 2Charger used. The type of charger used during charging will affect your Galaxy S4's charging time. This is because some chargers give a higher ampere output than other chargers. The higher is the Amp output of a charger, the faster it will take it to charge your phone.
- 3Power source. The power source will also determine the charging time of Samsung Galaxy S4. A phone charging through a USB source will charge slower that one on an AC power source. This is because USB gives a lower charging output than the AC socket. Also, USB charging is also not constant. A USB 3.0 may charge faster than a USB 2.0 port as long as the right cable is used.
- 4Device usage. Applications opened, radios used and screen usage will cause a longer time for your Samsung Galaxy S4. This is because any usage on your device will consume battery power. If you can avoid using your device while charging, then do it. This can help extend your battery life and lessen charging time for your battery.
Why does S4 battery take so long to charge?
If you compare it with other batteries, Samsung Galaxy S4's battery has a bigger capacity, thus it takes longer for it to be fully charged compared to other lower-capacity batteries. Also, there are a few things that cause slow charging on your S4. The output capacity of the charger you are using is the first thing to look into. Lower output amperage allows your battery to charge slower. If you are charging through a USB source, then it will take you slower as a USB 2.0 only gives 0.5A while a USB 3.0 gives about 0.9A. If you want to charge your device faster, use the AC charger whenever possible. Lastly, using your device while charging will make charging slower. This is because the battery is constantly depleting to provide power for the resources needed by your device. If you want to charge you Galaxy S4 faster, close all unused applications and turn off Bluetooth, WiFi and Hotspot sharing.
Why does my Samsung Galaxy S4 keeps turning the screen on when it gets done charging?
Your Samsung Galaxy S4's LED light will blink green when it has been fully charged and a charger is still attached to it. This is to give you a notification and a reminder to remove the charger as the battery has been fully charged. Aside from blinking green, the LED will also blink blue or red depending on the status of your phone. The following is a guide to the LED's blinking colors:
- 1Blue LED. LED will show blue under the following situations:
- LED will blink blue when your Galaxy S4 is on the process of booting up or shutting down (turning on or off).
- LED will blink blue when there is an unread message, a missed call and other application notification.
- LED will blue blink when your device is on the process of voice recording.
- 2Red LED. LED will show red under the following situations:
- LED will blink red when a charger is connected to your Samsung Galaxy S4 but it is not charging or there is a problem with the charging.
- LED will blink red when the battery levels are low.
- LED will glow red when your device is connected to a charger and charging while the screen is turned off.
- 3Green LED. LED will show green under the following situations:
- LED will glow green when your Galaxy S4's battery level is at 100% and the charger is still attached to it.
- LED will blink green when your screen is off and an application had just been installed.
To turn on or off the LED notifications of Samsung Galaxy S4, follow the following:
- 1Go to your Home screen by tapping on the Home key.
- 2From the Home screen, pull the notification bar down.
- 3Tap on the Settings icon on the upper right part of the screen,
- 4From Settings, tap on the My device tab.
- 5Under My device, tap on LED indicator option.
- 6Choose which LED indicator you wish to turn on or off.
- 7That's it. That's how you turn on or off the LED indicator of Samsung Galaxy S4.
Can you charge a Samsung Galaxy S4 through a computer?
Yes it is fine to charge a Samsung Galaxy S4 through a USB on your computer. However, you must take note that the charging speed may be longer than when you charge it using an AC charger. This is because the USB 2.0 port only has a maximum of 0.5 amperes of charge while a USB 3.0 has 0.9A maximum output charge. Charging through the USB may be practical when you are on your computer and Laptop or an AC socket is not available. It is interesting to note that you can also charge your phone using your Laptop even if the latter is not plugged in. This information may come in handy during brownouts and power failures.
Does using a regular charger for Samsung Galaxy Note3 hurt an S4?
A Galaxy Note3 regular charger has a maximum output of 2.0 amperes. This is just similar to the output of a Samsung Galaxy S4 charger. Basically, chargers of both devices are compatible so you should not worry using any charger from both devices to any of them. Also, it is a good thing to know that Galaxy S4, or any latest Samsung Android device, will only take inputs from a charger based on the device's maximum charging capacity so you do not need to worry that anything may happen if you overcharge your Galaxy S4.
There is no option just to charge the device?
If you just want to charge your phone and you do not want USB debugging functions with it, you can disable USB debugging on your device by following the procedures below:
- Go to your Home screen by tapping on the Home button once or the Back key for a few times.
- From the Home screen, tap on the Apps icon to see the list of available applications on your phone.
- From the Apps list, tap on the Settings icon to change your phone's settings.
- From the Settings, tap on the "More" tab to view more of your phone's settings.
- On More Tab, under System Manager, tap on the Developer Options.
- On the Developer Options, uncheck the box for USB debugging.
If the device is hooked up, you should not have to activate any feature to charge it. Now keep in mind some USB cables to transfer to computers aren't chargers, they are just data cables. Other than that, it should automatically charge once plugged into the appropriate charger.
My Galaxy S4 battery reduce early after its came at 65%?
When my cell was fully charged and I use it. After using 35% battery battery percent reduce to 14% from 65 % in 5 minutes.
There are many reasons why your battery percentage suddenly drops in big leaps. The following are the reasons and what you could do with them:
- You are using your device heavily. You may be opening and running too many applications at the same time. Close unnecessary applications. Applications are not closed when you press the Home button; they are merely minimized. You can check on this article Open, Close and Manage Applications on Samsung Galaxy S4
- Your phone got a glitch that made its processor run abnormally fast, thus draining your battery. If you feel that your phone got abnormally hot, immediately turn off your device and remove the battery. Wait for the battery to cool down before putting it back into your phone and turning your S4 on again. You can check on this article on how to Install SIM Card and Battery on Samsung Galaxy S4
- Your battery may not be in good health. If battery draining happens regularly, then your battery may be defective and in need of replacement. If this is your case, buy a new battery and dispose the old one properly. If the useful life of your battery was very short, then you may be a very heavy user or you are not taking care of your battery. Make sure that you do not let your battery drain. Ensure that you charge it as soon as its capacity drops down to 50%.
Your battery is not being fully charged which can either be a problem with the USB charger that you are using or the battery itself, one way to diagnose the problem will be for you to use another USB charger to see if the problem persists in order for you to recognize whether it is the USB or your device.
Looking to find what a blinking battery icon means when I have my S4 plugged in, but the icon does not show the charging icon just blinking battery
This is a problem with the charger. You can verify this be trying to charge with another charger. If you cannot find any charger available, you can go to a cellphone accessories shop and ask to try out a charger. If a different charger will work on your phone normally and you won't get the blinking battery icon, then buy a new charger and properly dispose of your old one.
This means that your device is not fully charging itself, the solution I made to help this situation was to was to change my charger. I learned that the charger I was using was not putting out enough power to my device to charge itself fully.

I couldn't charge my battery its keep showing 0% battery status?
My Samsung Galaxy mini2 battery not charging keep showing 0% and status with !(exclamation sign) I used new battery still is showing same please help me
Borrow a working charger and see if the battery still won't charge. Since your battery is new, the problem is now either on the phone or the charger. Use your charger to charge other phones to confirm if it is still working. If it won't charge with other devices too, then replace it. If it will charge, then the problem is possibly with your phone. Check on the suggestions on the question above if this is your case.
If you have used a new battery but getting the same result then you will need to first diagnose your USB chord to make sure the chord is in fact working properly. If the chord is working then it will be your charging port that is the problem on your device.

Do I have to wait for the light to turn green before I take it off,, been like 17 hours and not green yet?
Does light turn green, been 17 hours and still nothing ... when can I take it off
It should be showing you the green light on being fully charged. If the light hasn't turned green after 17 hours, it is probably not working. Check by going into settings and then going into battery, you will know if your phone is charged or not. If it isn't charged then there is something wrong with the phone and you need to get it repaired. If it is charged and the light is not on then, it is just the light that isn't working and you can get that repaired as well. In either case, you will have to go to the repair shop, only that it is o.k. to not go if it is just the light.

Why is the red light flashing on my Samsung S4?
I have never switched chargers since I've had the phone but tonight the red light starts to flash instead of staying steady when my phone is plugged in to charge . Its doing it on and off . when its flashing it shows my phone not charging
When the LED light blinks red, it means that the phone is connected to a charger but there is an issue with the charging. Do the following to determine solution:
- use another charger- if it charges, the charger is broken
- tried another charger, still does not work- charge the battery only using a universal charger
- charged battery from universal charger (full), still does not power on- battery pin issue or bad battery, try changing the battery (if issue is the same, it could be a battery pin issue) For battery pin issue, send the phone to an accredited Samsung Service Center to get it fixed
Battery Disconnected message on SS G4?
OK - usually charge SS G4 overnight. Woke up this morning with the battery at 80%. I unplugged the charger, plugged it back in and now get 'battery disconnected' instead of 'charging'. Never happened before - and now the battery won't charge ..Cheers
This could be a couple things. Either the charging adapter is bad or the charging port on the phone has gone bad. The best way to test it is to use a new charging adapter to find out whether the old adapter is bad or if it's the charging port that's gone bad.

It's not charging and makes a noise every once in a while?
Not charging properly either with computer or a power storage device
It could be a battery or phone problem. To know for sure, you need to use another battery (of the same kind and brand for the same phone), if it works on your phone, does not emit any sound when charging, it can indicate that the battery is to blame.Buy a new one compatible with your phone. However, if it remains the same, it could be a problem with your phone. I suggest you have your phone checked and fixed to use it efficiently again.
First, you will need to make sure that your USB chord is not the reason for the charging problem. Use your cable on another device to see if it functions properly. If the cable is working fine, then the issue will be with your USB port on your device.

I am having problems with the touch screen?
The phone is on but the screen is unresponsive
If the touchscreen is completely unresponsive then you will need to take it to a technician, or use any applicable insurance you may have. Now if it is slightly responsive or if you can go to settings, motion, sensitivity settings then select gyroscope calibration. That will allow you to hopefully fix the problem
Why my battery icon is colored white instead of green? There are many possible reasons why the battery icon indicator of your phone is white instead of green. The most common reasons are these:
- You are using a customized theme. Some themes alter the battery icon's color. This is not a sign of any problem though. Depending on your them manager application, check if there is a way to change the battery icon color. If you can live with a white colored battery, then that should not be a problem; however, if you are not using any theme-altering applications, then you may need to check on the next possible reasons why you have a white battery.
- Your battery is close to empty. The battery is colored full green when it is fully-charged. At 75% capacity, your battery icon will be colored white from top to the upper 25% of it, and green on the remaining parts. At 50% capacity, your battery is white from top to middle part and will be colored green from the middle to the bottom. When it is close to being fully drained, you battery will be colored white. This means that your phone will power off anytime and you need to charge it to keep it running.
- Your battery is defective. When your battery is defective, it may only show an empty battery icon even if it still has power capacity on it. You can check it by inserting your battery to another working Galaxy S4 and see if the problem is being replicated. If the battery is colored green on the other device, then it could be a problem with your phone.
- Phone's battery capacity reader is defective. As mentioned above, if the battery is colored normally on the other phone, then your Galaxy S4's battery capacity reader may be defective. You can confirm this by using a working battery, with at least half remaining capacity. If the phone show's a white icon, then you may need to have your device checked. Check if your phone is under warranty. Defects of this nature are, normally, part of the warranty coverage.
My S4 has recently started to turn off even when it has a lot of charge left in it, is there a way to resolve this problem?
My S4 turns off by itself even when its at nearly at full charge and won't turn back on until its plugged in
