iphone battery drain even while off?

[hasteveha]

When I first opened my iphone 4,the battery was completely dead. I had to recharge it to use it. Yesterday I charged the phone to 100% and then turned off the phone. When I came home today, I turned it on, and it's at 83% is that normal?

It shouldn’t lose that much, but you also shouldn’t be turning it off either. You want the ions to flow in these batteries, which means charging and then using the iPhone each day. The fact that it was dead when you got it doesn’t sound good either. Anyway, use it normally and if it’s still like this in a week, return it.

That shouldn't have happened...
But its better to keep the iPhone on and charge it from below 20% to 100% at least once a month to get the ions in the battery working at full capacity.

There have been many threads about this with no clear reason why. Some exchanged their phone and their new one worked fine. Some did a restore and got it working.

Could be a bad battery... Could be a running process just eating up the battery in the background. Or perhaps something else....

I got mine at the AT&T store with a dead battery. Had to wait while the CSR charged it enough to activate. The battery never held a good charge in the time I had that phone. I also had problems with the face recognition and a sticky home button. Took it to Apple and they agreed about the hardware problems ( I didn't mention the battery to them).

Got a new IP4 and It works fine. Battery life is way, way better than the other one.

Weird. I would suspect that you have a bad battery, take it in and get it replaced.

My iPhone does not do that.
