How OCD are you about the battery level?

[Beary]

I'll charge when it's around 50%. But I'll do a full charge once a month when it drop till 15%
I always make sure my iPad 2 got battery too
Cheers!!

The current iPhone and iPad batteries have a smart circuit that shuts down current to the battery when it gets full. That is built into the battery itself.

What you show happening is pretty unusual. Likely because one of the cells leaked oxygen. It's lucky it did not catch fire.

So you think it might be a result of a flaw in manufacturing rather than over charging? You think perhaps he should return it to Apple?

It does not have to be a flaw as it could be a result of leaving the device in a hot car - where temperature can get to 160 in the sun - when the polymer layers melt you could have a similar situation. If it was never in extreme heat then maybe it is a flaw.

We have all three variants here and I never bother with charging now.
When it gets to 5% it lets you know, but it doesn't do any harm to let it completely run out.
I just charge every morning regardless of the state of the battery and haven't noticed any degradation in charge duration.
