I accidentally left my iPhone 4 on it's charger connected to my computer for a whole month well I was away. Any damage done?
 
So I killed my battery... :(

I haven't seen any discussions of this anywhere as it pertains to the iPhone 4, but most devices these days that have a built in battery have a means by which the charger does not impact the battery after a full charge is obtained.
I'm guessing you will be ok.:confused:
 
unless the computer was on that entire month, there shouldnt be any problem.

In fact there shouldnt be a problem in the first place

Ok lets hope so

Thanks guys
 
Cycle it a few times (let it drain to ~5% and recharge). Replacement batteries are pretty cheap and easy to swap out, worst case. But considering it's still under warranty, Apple would probably exchange it for you if you could prove that battery wasn't holding a charge properly.
 
I completely agree with MLrollin91. I can't leave the house for 15 minutes without my iPhone, and the OP went 4 weeks? Sounds like you don't really need it so I wouldn't worry about it now. However it has a smart charger so the battery should be OK. It only takes what it needs to charge and no more.
 
When the battery is fully charged, it uses power directly from the USB/AC outlet, instead of constantly using the battery and recharging it.
 
Op it would have caused no damage to your battery what so ever. My phone sits on charge in a dock most of the day. Out of a month I'd say it's on charge for atleast 20 of them and I did the same with my 2g, 3G and 3GS, when it was away from the charger I managed the apple stated battery life.
 
It's actually better to leave the iPhone plugged in. iPhones only lose their battery capacity after being completely drained, then recharged hundreds of times. Leaving it topped off will make the battery last the longest. Just remember to drain it about once a month to make sure the on-screen battery indicator is correct.

ok

Thanks :)
 
it was better that you had it plugged in since the iPhone uses a Lithium battery and they last longer if you keep charging it when still having a big percentage of the battery left, basically topping it off wherever there is a plug will give you less full cycles and more life out of the battery (diff. than alkaline batteries). every 2 weeks or each month you should almost drain it just for calibration purposes that can be accomplished easily with a full days usage...
