ace - you might try another 1 or 2 hard resets. I wasn't 100% sure it was better after the first one i did, so i did it twice more. After that I was sure.
EWyatt - I don't recall any real functionality or performance effects of doing the hard reset aside from much better battery life.
Thanks for the tip, but it seems not to have worked. I took my phone in and they gave me a new one that came only with OS 4.1. I updated it to 4.2.1, did NOT get the Find My Phone app (don't need it), and my battery problem is just the same as it was.
Before all this I was the lightest of phone users, minimizing usage of apps to extend battery life, low
brightness, everything OFF, even WIFI, no Location
Services. I used to make maybe three short calls per day, very little texting (like one a day). Before I updated my phone to OS 4.2.1, I could easily average a week before charging, once going 13 days! Overnight I would see no battery decrease at all. On light usage days (most of them) my percentage would only drop from, say, 95% to 90%.
Now, with 4.2.1, my phone went from 70% last night before bedtime to 57% when I woke up. I haven't used it all day and it is now 15% (42% down in 9 hours of NOT using it). I continue to close all the multitasking apps although the only app I use anymore is the battery log application to see how the battery is, and that is pretty depressing. On the few days I tried to use the phone, the battery log app shows a vertical line STRAIGHT DOWN. If I was a serious user of the phone, I'd have to charge it twice or three times a day.
I've done the hard resets a bunch of times, continue to have everything off, and the brightness all the way down. My phone is now giving me about 15% of the battery performance it did when new. I think it is the result of the 4.2.1 upgrade because that is when it started. My iPhone 4 is now essentially no more than a battery meter. I hate it when I get calls because I know how quickly the battery is draining. I will continue to watch it, but it looks like a trip back to the Genius Bar is in my future (and that had no effect the last time).
