this is 2010, and simply not true anymore, I follow Apples guidelines.I think charging full from under 5 percent or less is important
Notifications on.How good is the signal in your area? Push email or push notifications? What do you typically do with your phone?
Well this is from 100% to dead.7 hours....wow...I just fell down from my chair! Even if I turn on my 3G signal I get let's say 5 hours of usages, 1 1/2 day standby!?...do you close all these multi-tasking...or?
7 hours is nothing!? You should at last have 1 day! Have you tried everything - restart the iPhone etc?Well this is from 100% to dead.
And I only keep IM+ in multitask.
Also my phones brand new so the battery hadn't had a chance to die yet. After a week or two it will go down I'm sure.
