Hi. Hope someone can help. Just now my iPhone 5 hit 19% so I plugged it in and immediately the battery % jumped to 22%. This has happened a few times lately. I let the phone drain flat a few days ago so it should be calibrated. Has anybody else noticed this? Is it a glitch in ios7? I afraid if it continues it will throw off my %'s completely. Thanks for any help.

I've heard of that when using a car charger. But not plugged into a wall outlet.

I am not on iOS 7, but I have not heard of this happening. I do know that when you reboot your phone even when it is not on charge, usually the % will go up. As people have said, the % is usually not an accurate look of your battery.

Hey buddy.
Yeah this has happened to me several times.
You can fix this by calibrating your battery.
This involves letting your phone die, then charging it till it's 100% again. Let the phone truckle charge( leave it for an extra 5minutes on the charger).
You don't have to do this but it helps set your battery and improves the accuracy for display.

What denzel1989 has suggested to do will definitely help your issue, but the unfortunate thing is that your battery will continue to be off unless you calibrate it often. I actually just had the issue the OP had. My iPhone 5 iOS 6.1.2 finally came on even at 0% and stayed on. I got back to my home and put it on charge and it immediately went from 0% to 7%. I have never had that happen to me.

Thanks for all the replies. Yes I did calibrate it a few days before but I'll do a few more calibrations and see if it works it out. Thanks guys.

I would not say that it is needed to calibrate every day, but it is nice to have your battery percentage be a definite look as your real battery percentage. Sometimes my iPhone turns off at 13 or even 25%. Very crazy.

That's true. I don't intend calibrating it every day, not good for the battery to lot it go flat too often.

For me, I don't calibrate often at all. But then again, it's sad to see my iPhone turn off at such weird percentages. Today it turned off, and then 15 minutes later even when not on charge it turned on and showed 7%. Then it immediately went from 6% to 0% and stayed on for over an hour. :LOL:

That's what I'm afraid of happening. The %'s just seem so weird. Ill monitor it for a few days and report back.

Please do report back. I am curious to see if calibrating once every now and then actually does help.

There is nothing wrong with it. The battery percentage is just an estimate. It sometimes dies at 5% and other times it lasts for ten minutes at 1%.

I am curious though to read your response to why my iPhone once turned off (died) at 30%.

Because it needed to be calibrated. That calibration doesn't last forever so you'll typically have some variance in accuracy. I just use the phone and try not to fixate on battery life or accuracy of the remaining percentage.

Oh I don't fixate on the accuracy of the remaining percentage either. It's just funny to watch it. Right now my phone has been put on charge when it was at 0%. I'll leave it on charge a little while after 100%.
