Fix iPhone Battery Percentage Problem for iPhone 6 and 6 Plus or S Series iPhones

Edited by Train Wreck, VisiHow, Eng, vc and 1 other

There are only a few things that can go wrong with your iPhone 6, 6s, 6+, or 6s+ battery. However, with newer model iPhones and batteries, technical faults that require replacing the battery are rare. Most problems you have with your iPhone battery can be fixed without a repairman or with VisiHow as your repairman. Perhaps the easiest of these problems to fix is when your battery is not showing the correct charge. This can happen when you see your battery might be at 30 % or 20 %; and then, the charge immediately drops down to 10 % or 5 %. This happens when the phone's operating system loses synchronization with the battery. It's actually quite easy to fix. Read on for our tutorial on how to fix your battery when it's reporting the wrong level of charge. Don't forget to check out our article on how to increase iPhone battery life when you have finished!

Restart the iPhone

Many times, simply restarting your iPhone will correct the problems with your battery. As you will see in the section below, we take an iPhone with a 9 % battery charge, plug it into a charger, and then restart it. Once we've restarted the phone, the battery shows 22 % charge. This is an increase of 13 %. Even allowing for the time spent between plugging in the charger and taking the photos for this tutorial, we can see at least a 10 % increase in battery charge in five minutes or less. That means that our iPhone should fully charge from zero battery up to full battery in less than 50 minutes. Obviously, this is unrealistic; and it indicates the software problem that we will show you how to fix now.

    In the image below we have an iPhone
    .
    This iPhone is currently reporting 9 % of the battery charge. The problem is that about 20 seconds ago, this phone indicated that it had more than 20 % battery.

    If we plug in our iPhone charger, we will see that the battery level does not change
    .
    Plug your iPhone into the charger now. Do note that occasionally you may see a jump in battery; however, usually you will not.

    Next, we are going to press and hold the power button to shut down the iPhone
    .
    Simply hold the button until the 'slide to power off' icon appears. Then, slide the screen to turn off the device.

    Once our phone has powered itself down, we once more press and hold the power button until we see the Apple logo
    .
    Once we see the Apple logo, we release the power button. The iPhone should reboot after a moment.

    When the phone has been restarted, take note of the battery percentage
    .
    Sometimes, it will be increased; and other times, it will still be low. Simply wait 3 to 5 minutes, and you will see a significant increase in battery life. In our case, you can now see the battery life has been restored to 22 %. For those of you paying attention, the last time shown on the phone in our photo was 12:54 PM; and the time in this photo is 1:02 PM. That's only eight minutes. Keeping in mind that we are writing a tutorial and taking photos as we do this, we can safely assume that at least 10 % battery was restored over a five-minute period.

    This is how you quickly restore battery life without resetting phone data or settings
    .
    You can see in the photo below that over the last 12 minutes, our battery life has increased approximately by 10 % more. This is still somewhat unrealistic in terms of how much the battery really has been charged, but it's much more accurate than the 10 % battery life we gained earlier in five minutes.

Additional Tips

  • Remember that there are many different things which can cause your battery life to display incorrectly. Most of the time it just requires a restart.
  • The most popular problem with the sudden battery drainage is cold. You must operate the phone only within the indicated temperature range: from 32° F to 95° F (0° C - 35° C). If your phone has been exposed to lower temperatures and shows a lower percentage or turns itself off, you will need to warm up your phone to the operational temperature to restore the battery percentage. You may resort to keeping the iPhone phone in the pocket closer to your body or warm it in your hands to turn it on for a minute and make a quick call.
  • Make sure your iPhone is running the latest version of iOS, as sometimes there are application errors that can create problems with the operating system for specific phones.

iPhone 6, not charging properly?

Has been an off / on issue for sometime, but not until this weekend, a real concern. At times when plugging in, it'll make the charge sound, other times, no. Mostly when starting to charge, or at least making the appearance that it is, the battery level slowly decreases. I've tried 4 different chargers, and have reset or powered off numerous times. Any ideas?. I have tried: See initial question. I think it was caused by: Not sure. Phone gets lots of use.

Why does my iPhone say its charging, not while its plugged in, but RIGHT after I actually unplug it?

My battery life was all over the map today, fluctuating anywhere between 1% to 86%, going up and down all day. I ran Google maps for about 10 minutes, plugged it into the charger in my car and watched the life drain right out of it. I've plugged it into the wall with an Apple certified charger and nothing. A few times it lit up with the Apple logo. But now nothing. If I press the Home button (while plugged in) it just shows the low battery symbol. If I unplug it, the second I do, the "charging" symbol appears (but it's UNPLUGGED at this point). I've had it plugged in for the last hour, but not straight. I've unplugged it and plugged it right back in every 15 minutes or so. Same every time. Is it toast? The "charging" symbol appears once the phone is unplugged.

My iPhone 6 battery fluctuates frequently after battery change?

Just replaced my iPhone 6 battery and screen, but noticed that it charges phone to 100% level and stays like that for a while in use. But when I turn off and on again it shows no battery level at all, and requires charging which takes a lot of time to charge as well.

iPhone 6 charge problems. Phone turned off just minutes after it read 47% charged?

I've read all the posts concerning this charging problem and except for the suggestion to reset the settings, there is no other solution that I can find. Dozens of complaints about this problem; the page has been read more than 5,600 times indicating the extent of this problem, and still no solution? The phone is useless to me if I can't count on it working properly without being plugged in. Just this morning I was using maps to get about 20 min away from my destination when my phone went blank. I couldn't call (no phone), didn't know where I was or how to get back home. When will there be an acceptable solution for the hundreds of thousands of iPhone 6's out there? It is the same situation but left me stranded in a town I've never visited before with no way to call or find my way home. Why is there no solution? I have tried: Reboot and reset settings. Nothing worked. Looked on line for solutions only to find this is apparently an established problem that no one if fixing. I think it was caused by: No idea but it is more than frustrating. It left me stranded in a strange town with no map or phone
