Adjust Display Brightness

Your iPhone offers a very modern system for determining the appropriate level of screen brightness. However, often that level of screen brightness is more than it needs to be. In such cases, you will want to disable the automatic screen brightness and set something that is more suitable to you. If you plan to be spending a long time in an office, then set your screen brightness to an appropriate level for your office. Likewise, if you're going to be out in the bright sun, then adjust your phone brightness accordingly.

Enable Low Power Mode

The low-power mode is a great iPhone battery-saving feature that automatically shuts down many of the common iPhone power-hogging features. It only takes a moment to turn it on. The feature automatically turns itself off once your phone reaches 80 % or more in the battery charge. This is a useful feature for people who forget to disable the power-saving mode after charging their phones. If you always have a battery-saving mode on, your phone charge will last significantly longer.

Check App Usage

Applications use battery differently. Some, like Facebook, are notorious battery hogs. We recommend uninstalling these applications completely. That's discussed a little farther down in this tutorial. You can easily check which other applications are using the battery the most. If you find that an application you don't normally use or an application that you do use is using up too much of the battery, you can disable or remove it. Read on to learn how to check application usage.

    From the battery menu indicated in the steps above, you can scroll down to see the applications you have used recently and the amount of power consumed by them.

  2. 2
    To receive detailed information about these apps, tap once on any application to see a detailed list of what's been used and how much of it was used.
    For example, you can see that that the WhatsApp iPhone application was used for 21 minutes and worked for eight minutes in the background. This used 7% of the battery.

  3. 3
    At the top of the battery usage menu, you can also see applications used in the last 24 hours or last seven days.
    This is also helpful in determining where battery life has gone over time as opposed to the last 24 hours when you may have been chatting more than usual.

Disable Background Application Refreshing

Many applications are set to automatically update information and refresh their newsfeeds. If you do not need up-to-the-minute information or if you may not benefit from these services, then you can disable applications that automatically refresh themselves on your iPhone. This may be when you are at work and your iPhone is constantly updating a Facebook feed that you are not looking at more than a few times a day.

    Disabling background applications is very easy to do.
    If you already have the low-power mode enabled, then background application refreshing has automatically been disabled. If you do not have the low-power mode enabled, then simply navigate to the 'Settings' option on your phone by tapping once on 'Settings'.

Uninstall Facebook and Messenger

The worst application on the iPhone for draining battery is Facebook. This is because the application tracks almost everything you do on your phone and constantly maintains connectivity, even when you have disabled these features. Most of the time, you will see a 15 % to 20 % increase in battery life by using the Facebook Web application as opposed to the built-in Facebook application.
