I can usually get 15 to 20 hrs with wifi off, iPod running podcasts and about 1 hours of calls in between, moderate text and email and brightness at 95%. But throw in a day like yesterday when I am in a building with little or no signal and I was down to 30% after 5 hours. Bottom line is battery life is different for everyone and location can make a big difference.
I wouldn't worry about the actual usage time. If it makes it through the day that's good and just charge it every night. Turning everything off like that kind of defeats the purpose of having an iPhone IMO. Although I will say since getting the 4.1 OS wifi seems to really eat the battery if you leave it on now.
Yeah. It's better then the life on my 3GS and I appreciate the comment about not worrying about usage so much. I guess reading those boasts about people getting 15-20 hrs with heavy gaming and all bells and whistles got me panicky. I'm loving my phone !!!
yeah I'm loving my battery life on 4.2.1 but you just have to remember to plug in when you can. I don't know why people think plugging in the phone more than once a day is like a crime? I think alot of people came from basic cellphones which didn't have anything except a phone and the battery lasted for days so now we've gotten used to that being the norm.
