The latest iOS 7 upgrade has brought the spotlight on the issue about the new system being a battery life sucker. The main reason for this is that some of the features get turned on by default draining all the battery life out of the phone.
If you are looking to save battery life, regular things like reducing the brightness will always help. Here are some extra tips that could help you out if you happen to own the latest upgrade of the iOS 7.
App Refresh: The newest feature in the upgrade is the automatic application refresh, which updates all applications to their latest versions. All you have to do is to switch off the updates under the Automatic Downloads section (Settings > iTunes and App Store). While you are there, you can switch off the other automatic downloads like for music, books and apps individually, as well, to make sure that they are not running in the background.
Wallpaper: The new parallax 3D view for the home screen and the new animated wallpaper look pretty, but they also drain your battery out! The parallax 3D view settings are in a weird place, and a little hard to find. Just switch ON Reduce Motion (Settings > General, Accessibility) and then you are good to go. Animated wallpapers are not installed as default, but in case you do have one, it is pretty simple to turn off. Just pick a simple wallpaper instead of one that is dynamic (Settings > Wallpapers and Brightness >Wallpaper).
Location Tracking Apps: There are a lot of apps that are tracking your location at all times. If you have installed such apps on your phone, then you have two options; either turn off all location tracking services completely (Settings > Privacy > Location Services) or you can disable applications one by one. The latter is a better option if you still want to keep the essential location-based functions like Find My Phone, etc.
