Battery problems with iOS7? Here's some suggestions.
As people upgraded, reports starting pouring in about battery drain. Here's some help.
- Turn off the 3-D home screen wallpaper that is standard with the new IOS.
- Disable "Background App Refresh,"which automatically updates and refreshes apps even when you are not using them.
- Turn off "Air Drop," which looks for iPhones nearby.
- Turn off WiFi searching.
- Dim the screen. the age-old solution to battery life issues.
As for holding off, or removing the upgrade, you really can't do that: if you stick with IOS 6, you will start having app problems soon.
