1. Say Goodbye to Motion
iOS 8 has a great number of visuals with plenty of zooms, icons and even a few floating graphics than other iOS versions. While these looks great on iOS 8, they also use a lot of power to run on your display. Putting the motion control feature on a diet can increase your battery’s life. Move down to Settings > General > Accessibility and turn the Reduce Motion feature to the off position. This should not only boost your battery, but also your processing power.
2. Manually Turn off Background Apps
One of the best battery boosters for iOS 8 is to turn off the apps running in the background. Even when you close your apps, some continue to run on the background of your Apple devices refreshing automatically. Turning this feature off will increase your battery. Simply go to Settings > General > Background App. Refresh and turn off all the apps you don’t mind refreshing manually.
3. Download When You’re Ready
While automatic downloads are mighty convenient, it’s best to live without this little feature. Go to Settings > iTunes & App Store and click on Automatic Downloads. Flipping this switch off will get the app to stop checking in the background for new downloads, and you’ll save quite a bit of your battery.
