So I updated to iOS 7.1 yesterday around 2PM from 7.0.6 (I previously had 7.0.4, 7.0.5, etc). I had 87% battery, and closed all apps before starting the update - I did however, update OTA. Normally I am quite keen on my battery life and drain throughout the day. I notice when my phone has been sitting on my desk for a while exactly how much the percentage has gone down (or not gone down) whenever I check it. Generally speaking (on iOS 7.0.4-7.0.6), if my phone is on my desk, and I'm not using it (only receiving emails from one account) it'll drain maybe 1-2% in a couple hours (this is assuming I am not in a texting conversation). After updating to iOS 7.1, I messed around for 5 minutes or so checking out what was changed (animations, etc), and then I put my phone back down. The next couple hour period it had drained 4%, doing nothing different. After a few hours I noticed this was a constant thing, so I charged it fully to see if it needed to re-calibrate or whatever. That night I put my phone in do not disturb before bed and for 8 hours it just sits there doing nothing. It generally drains 1-2% (on 7.0.4-7.0.6), but last night it drained 5% overnight. Also before bed I was asking Siri some questions (Just stupid things like tell me a joke - 4 to 5 times until she finally told me one ) and the battery had drained 4% in the 5-6 minutes I was talking to Siri. I noticed a little bit yesterday that active use seemed to drain battery a little more than usual too (other than that one time with Siri). Anyway I just wanted to ask if: 1) Other people have noticed the same thing (as I thought 7.1 was supposed to improve battery even further) 2) Maybe mine is just a little messed up because of the OTA and I should try to reset and then restore my phone to see if that fixes the drain... P.S. It's not like a huge drain, but I was very happy with how efficient my phone was before (especially in standby). Even though it's only maybe 10% worse now, it feels like I have to worry about my usage now, which I have never really had to do before.
