Updated: July 29th, 2013 I know a lot of you are complaining about battery life, so I've decided to make this thread and point out how you can get your battery life back to what it was, if not even better then when you were running iOS 6. I'll keep updating this as a filter through log files. It's not an easy process, and it took a little bit of reading through log files and testing to figure this out. Please follow this advice carefully. This will fix 99.9% of your battery problems. I've fully tested this myself with several devices (including older generations) Instructions: (Each instruction has an explanation below, the numbers do not signify any form of order) 1) Install each beta as NEW. 2) Sign out of all signed in services (see below for list), then sign back in. 3) Location services (if turned on): Disable Popular, Frequent Locations, Location iAds, WiFi Networking. 4) Turn off Bluetooth unless needed. 5) Do not use the new "live" wallpapers. 6) Turn off "Background App Refresh" User friendly explanations: 1) Avoid OTA updating the betas.. but if you must, reset all media/content via General -> Reset. The way iOS 7 handles OTA updates may cause some compatibility issues if you've already installed apps, services, etc. Fresh install without OTA/backup is the fix at the moment. 2) This will clear any IdentityServices issues. Currently iOS 7 has a bug with authentication/identity services which clears after logging in and out, then back in. You may sign in again once ALL services are signed out. 3) This will clear out LocationServices bugs on first use. Right now iOS 7's geofencing and other location services (including the new ones) are not working right and WILL drain your battery. This fixes that issue while still giving you nearly full location services access. 4) Since iOS 6 Bluetooth is automatically enabled (with no icon) and you must manually turn it off. 5) Yes, the new wallpapers are battery hogs. Right now, they cause severe drain and logging issues (As seen under diagnostics) so for now, stick with a standard wallpaper. By the time iOS 7 is out, I'm sure this will be fixed. 6) Currently not working as intended, instead leaving apps completely running as code is not optimized. Turn this off and you will notice a huge improvement (and wont affect multitasking!).
