If you have upgraded to iOS 7, your battery life may be reduced. According to multiple posts around the web, including Apple’s own technical support forums, different people’s battery life will be affected to varying degrees. For those of you who have trouble getting through the day on a single charge, here are some tips:
Close all non-essential items
In terms of battery consumption, Bluetooth and Wi-Fi are the obvious candidates. If you don’t turn them off completely when you don’t need them, remove them from the list of previously paired devices to ensure your iPhone or iPad doesn’t connect to Wi-Fi networks and Bluetooth accessories unnecessarily.
Turning off cellular data means you won’t receive email notifications, Whatsapp messages or any other app alerts, but it will also significantly improve your battery life expectancy. To do this, go to Settings > Cellular and move cellular data Slide the slider to the left to turn it off.
For a less drastic approach, you can decide which individual apps are allowed to send and receive data when your phone is idle. Go to Settings > General > Background App Refresh Selectively choose which apps are allowed to use your internet connection to refresh themselves.
Apple’s mobile operating system also uses background data transfer to sync iTunes purchases, iCloud backups, Photo Stream, and more. If you don’t need them, turn them off – Of course iCloud is very convenient, so don’t turn it off unless you really need it.
App notifications also require internet access, so turning some of them off will help you manage power consumption. Go to Settings > Notification Center And disable spam magnets like games and business apps.
AirDrop doesn’t require Internet access, but it can use your Bluetooth and Wi-Fi radios to check for compatible devices near you. Turn it off via Control Center, which can be accessed by swiping up from the bottom of the screen.
While you’re in settings, go to Privacy > Location Services And check which apps have used GPS recently. Turn off location services for apps you don’t need, such as promotional apps that try to detect when you’re near a brand store.
Another very simple thing to do is to manually quit apps running in the background to ensure they aren’t silently wasting energy when they shouldn’t be.
Give up eye candy
iOS 7 introduced many famous visual effects, including animations for most screen transitions and wallpapers that move when you tilt the device. These can be closed from Settings > General > Accessibility > Reduce Movement.
Of course, one of the easiest ways to manage power is to turn down the screen brightness. Control Center makes it quick and easy to adjust brightness as needed, so you can only turn it on when you need it and ensure automatic settings aren’t too wasteful.
Reset, restore, reinstall
If none of these tips work, or you determine that your battery usage is much higher than normal, you can always try resetting your phone. In some cases, users who have upgraded to iOS 7 and/or 7.1 on their devices themselves have reported improvements after resetting and restoring via iTunes on their computer.
The least disruptive step is to reset all settings, via Settings > General > Reset. This will keep all your applications and data intact. Selecting “Erase all content and settings” will reset your phone to its factory state. For a complete reset, plug your device into your PC or Mac and use iTunes to reset it. Doing this will install a fresh copy of iOS 7.1 on your device.
last words
More importantly than that, only charge your device when necessary and don’t leave it plugged in for long after it reaches 100%. Cycle the battery thoroughly every now and then, and let the device cycle a few times after the iOS 7.1 update so the battery indicator can be properly calibrated.
