iPhone 4s Battery Life?

My iPhone 4s battery seems terrible! Almost equivalent to my 3GS and it's terrible battery life. When I got my iPhone yesterday and restored from backup I noticed nothing really changed with minimal usage and standby! Is this normal or should I consider setting it up as a new phone because maybe something is running in the background that's causing it to drop a percentage every few minutes under light usage? Input would be great!

My 4S seems to drop 1 percent every 3-4 minutes when in use, which seems acceptable, but the real problem is the battery loss when in standby. It has been dropping 1% or more per hour when in standby, so I did a DFU restore in itunes. Last night, however, it still dropped 1% per hour. Is this normal? It seems like it shouldn't be dropping 1% per hour in standby. Could it be that I have wi-fi enabled when at home?

BALONEY! That would give you 33 hours of USAGE TIME per charge. IMPOSSIBLE. We don't need hyperbole in here as there is already enough mis-information spewed.........


Why don't you tell that to the other thousand users in this thread, and for your information it is not mis spewed information. It's a fact from my experience with my old iphone 4.

I'm actually surprised, i thought it would have lasted like 7 mins per 1%, guess I was thinking wrong?


No your not thinking wrong. It's suppose to last at least 15 min under normal usage before the battery would drop based on my experience with my previous iphones.


( iphone 3g, iphone 3gs, iphone 4)


Currently now using the iphone 4s

sorry to but in...i'm a (lowly) itouch user with similar battery problems, but who WAS thinking of switching to an iphone on the theory that iphone battery charges would last longer; but apparently this isn't the case. surely there are definitive answers to this problem?


anyway, would an iphone even work WITHOUT phone service - e.g. could i play music, use the calendar, etc?

Look. 33 hours of USAGE is impossible. You are either lying or mistaken. You decide which.......
