Same with mine when I unplugged yesterday, within minutes was down to 99-98% but overnight I only lost about 2-3% on standby which is an improvement I think
Just to clarify...I get the 1-2% drop instantly on unplug from power.
I think it's no problem and you don't have to worry about anything.
Had the same thing this morning. Unplugged, plugged back in again and it charged back up.
Then stayed at 100% for ages before saw any drop. <shrugs>
It's happened with all my iPhones. Likely didn't notice it. Once it gets to 100%, it stops charging (or trickle charges). Instead of constantly charging to keep it at 100%, the phone allows it to drop a percentage or two, and then starts regular charge to top up again. This is my theory anyways. There is nothing wrong with your phone.
Most likely, but not definitely. And that my concern. Maybe it's a countdown issue and that last 10% will last us two hours, but maybe the hardware is too powerful and dual core means twice as fast battery drain.If you look around on this forum, you'll see there are ALOT of people having battery issues.
Most likely a software issue.
I really want an answer because I hate that I've disabled so many selling point features just to last a full workday.
When I look at my 4S in the morning from an overnight charge it shows 100% while showing the full charge icon. As soon as I unplug it it drops to 98% or 99%. I've never seen any phone do this. Including my iPhone 4 before this.
When this would happen on my iPhone 4 or 3GS, I would just restart the phone and it would "recalculate" the battery correctly. It would just happen randomly... like I would be using it for 1 minute and I would notice it at 98% so I restart and I'd be back at 100%. Don't know if that helps or not.

Yeah I experienced this with my 4 also.
However this didn't help with the 4s. It came back up with the same 98% charge and began to deplete quite quickly with light use.
