I don't know how they managed to make battery life worse, but I've dropped 8% in 11 minutes with beta 3. Wtf.
From just this morning's experience for me, battery is worse. 100% to 68% by the time I got to work!
I had been using Spotify for iOS 4 so I don't know whether that app uses more battery than the new version? 😕
Well I think any app that's not optimized for your OS will probably have subpar performance, so maybe try the newest version until they can optimize it for ios 7.
I always do clean installs and always reset all settings + turn off all the usual features. Beta 1 was brutal, beta 2 was a slight improvement, beta 3 feels like beta 1 again or worse.

Was off charger at 8am, ran GPS for 5 minutes, Facebook for 10 minutes, Twitter for a few minutes, and listened to a 45 minute podcast. Still at 100%. The Podcast app is definitely better with beta 3 than with beta 2. Was having insane heat issues running that app on beta 2.
Me too.
After 50 minutes of disconnecting it from power, including 10 minutes of music via bluetooth, 5-10 minutes of Kindle, checking Mail and Twitter and some other random stuff (no games or videos), my iPhone 5 is still at 100%.
Which I find strange. Too good to be true.
. . . batter on my iPhone 5 . . .
Isn't it strange how much difference certain apps and settings must make?
My experience has been the complete opposite.
Surprisingly good on Beta 1, poor experience as a whole on 2 and now best, so far, on 3.
With the exception of not using auto updates other than when on charge, I've not compromised any other settings.
😱
You must come from Glasgow in Scotland.
They'll fry anything in batter up there !!!
Mine stays at 100% for 45 minutes before starting to decrease. 3 hour 9 minutes standby and 1 hour 39 minutes of usage and I'm now at 83%. I'm on wifi. All the usual features associated with battery hog such as Parallax and Background App Refresh are disabled.
I haven't had much of a complaint on battery life with the betas, but wow. Beta 3 has been absolutely atrocious. I always do a clean install just to start clean and I just made a 10 minute call over talkatone and dropped from 100% to 84%. I have never seen a drop so rapid on any phone, and I had the infamously terrible on battery life Verizon Gnex. Wonder what is causing the drainage this time around.
I am getting horrible battery on beta 3 it's insane.. Is there anyway to fix that?!?!
