iPhone 4 battery won't charge to 100%

[urbancity]

Hi guys,

I have a four day old iPhone 4. I've noticed that even if I charge my iPhone overnight (typically from 11-6:30am), the battery indicator does not reach 100%. It reads 93-94%.

Is this normal, and if not how should I charge my phone such that it's fully charged?

Turn off the phone and then turn it back on after a full charge. It should display 100% then. I have this problem every now and then.

The problem is not the battery it's the percentage meter it is not working I had the same problem Go to settings->General->usage->Battery percentage turn it off then on reset your iPhone while it's on by pressing home and power at the lock screen for 10 sec don't touch the slide to power off just keep pressing till apple logo pops up then everything will be regular (nothing will be erased)

If the above two suggestions don't work. Try running it all the way down, 0%, til it shuts off on it's own.

Wait til one evening when your low, then play a game or something battery intensive to drain it.

Then charge to full overnight. The 0% to 100% swing triggers a recalibration of the sensor.

It's not totally far retched that charge levels may have drifted a bit depending on how long it was in storage and what temperature swings it might have experienced .

Apple recommends this procedure once every month or so anyway for battery health.

If the battery backup is fine, then there is nothing to worry. Make sure you don't overcharge your battery!

You cannot overcharge an iPhone battery. The charging circuitry shuts off automatically.
