Explain this... battery issue.

These battery issues are getting out of hand.. consult Apple right away. You may be able to get a replacement.

 

The battery percent indicator is just that, an estimated indication how much charge is left in your battery. It is not an accurate depiction of the current charge. If your battery has had wear and tear, then the indicator will vary even more so.

 

Like Jav said above the percentage indicator is off sometimes and phone battery needs calibration. Don't rely 100% on it and don't take it as completely accurate all the time.
I had my battery at 10% and my phone turned off. And other times it went down to 1% then shut off.

 

And I've had it show 1%, but last for another 2 hours. It just happens.

 

Mine was fine before the update to ios7... since then it has been doing the same thing. I contacted apple about it a while ago still nothing yet..

 

Today mine (iPhone 5, iOS 7.0.3) showed about 60%, then the little 're-spring' circle of white dashes blinking, then dead. Press power button- and the 'plug it in; it's dead' screen showed. Plugged it in, turned it on and battery immediately showed 60% and started charging, too fast I might add..at least going by what the screen showed.

If we can't even have the "phone's best guess" be remotely accurate for battery drain, then why show it AT ALL? We should just always assume it has enough juice for only one text message, and carry a charger/solar panels everywhere.

This is ridiculous. Mine wasn't doing this before iOS 7, either.

I already emailed a local authorized Mac repair place, I'm going to make an appointment and see if they will replace the battery. Bought mine in February so it does have a warranty still.
