I know there are tons of threads on this but I'm starting this one anyhow just for visibility. Background: my iPhone 5 had good battery life in Beta 6 and GM but when I downloaded the public release and updated through iTunes my battery went to hell. I went through the basics of turning off parallax, background refresh blah blah. Last night I put my phone in DFU mode and did a restore to public release. My battery is way more stable now like it was in Beta 6 and GM. Note: For those of you who use Tapatalk I think you should know that the app does a auto-refresh every 30min as a default setting. You may want to turn it off.
