7 Fixes & Tips for iOS 8.1 Battery Life

We’ll show you iOS 8.1 battery tips to help your iPhone last longer and iOS 8.1 battery life fixes that help find the reason your iPhone runs out of power so fast.

On average you should expect between 8-12 hours of use on the iPhone 4s and newer, though it varies based on your usage. If you are seeing battery life less than 10 hours you may need to fix a problem, rather than make a small tweak to keep the battery going longer.

1、Find iPhone Apps Using Your Battery

With iOS 8 and iOS 8.1 Apple makes it easy to find the apps that are using your battery life. When you find an app that uses too much battery life you can limit your use of it when away from power, stop background activity or remove it completely.

You will also see where poor coverage is to blame for bad battery life. When your phone needs to search hard for a signal it runs the battery down faster, so keep that in mind and you may need to turn on Airplane mode when you have no real cell signal.

Go to Settings -> General -> Usage -> Battery Usage to see which apps use the most battery life in the last 24 hours and for the last seven days.

Limiting Facebook and games during the day is an easy way to stretch the iOS 8.1 battery life longer on your devices.

2、Limit BackGround App Refresh

The iPhone can refresh apps in the background so that the data is there when you open the app. This is very handy, but even with smart updating in the background it does use more battery life.

Instead of turning Background app refresh off completely, you should find apps that use it too much and turn it off for them one, by one to see if that solves any iOS 8.1 battery life problems.

Go to Settings -> General -> Background App Refresh -> Turn it off for each app that is using too much power.

3、Stop Using Auto Brightness

The iPhone and iPad include sensors to change the screen brightness based on the light in your environment, but too often the device will boost the screen brightness to obscene levels.

  Control brightness on your own for better iOS 8.1 battery life

Go to Settings -> Display & Brightness -> Auto-Brightness -> Off and you will soon see the benefits of keeping your screen at a reasonable brightness level.

You can always turn it up or down on your own when you need it using the Control Center.

4、Restart or Reset Your iPhone

If you notice that the iPhone battery life is very short or that the iPhone is warm, you need to restart it or reset it. Simply hold the power button and slide to turn off for a normal restart.

You can also reset the iPhone by holding the iPhone home button and the power button for about 10 seconds. This will not remove any of your data, but sometimes this is enough to fix whatever was draining your iPhone battery life.
