In my last report on this I noted that an Apple phone support person (Patrick) had me completely reset my iPhone: back it up to iTunes, reinstall iOS5, then sync my stuff back onto it.
When I did this yesterday it seemed to be helping, a single full charge lasted all day and while I wasn’t using Siri heavily (Siri was down yesterday) I did various things with the phone during the day.
Last night when I went to bed I noticed that the phone was at 78% charge and I left it unplugged to see if standby mode would wipe it out again. The phone was connected to our wifi network and to our AT&T macrocell so I assume that it’s nightly maintenance connections got made and it was active during the night.
The good news is that this morning it has a 76% charge on it, only losing 2% overnight.
No doubt the update to iOS 5 will improve battery life even more but there is now no doubt in my mind that completely resetting the phone helped a lot and people who have this problem should at least do this step, it can’t hurt.
I may eat these words in the next few days: I’ll be in New York tomorrow and I have a friend coming to visit who’s an iPhone user and who will want to mess with this new phone. My phone will get a good workout and we’ll see if Patrick’s “fix” is what I think it is. But I’m a lot happier today than I was yesterday, and this is a good thing. Of course, having electricity in the house (finally) doesn’t hurt.
