iPhone 5 battery issue - drains and then gains quickly

[webitorgal]

For example, my battery was at 85% around noon, but went quickly down to 60-something % by 1. However, as soon as I plugged my phone back in, it jumped back to 78% I know that it had some problems with LTE earlier, but that was only for a short while. Has this happened to anyone else? This is a recent issue - as in over the past couple of days.

I have had everything synced through iCloud. On occasion, my battery would be killed really fast. I did some research, syncing Safari bookmarks through iCloud was the culprit.

So, if you use iCloud, turn off Safari.

Hope this is the case.

Nope, Safari isn't synced. I only have Passbook, Find My iPhone and Reminders on sync!

I had the same symptoms and in my cause the battery was faulty. Had it replaced at the Apple Store, 0 problems since then.

I have the exact same question. I think that how you charge it might matter. Are you using a licensed Apple charger in a HUMIDITY FREE environment? My iPhone charger was in the bathroom, but the humidity made the charger violently overheat after some time.

Interesting you say this. I've just switched my phone off at 92%. I then switched it back on again and now it's showing 97%. Since browsing on here I'm back down to 92% again. Why is that?

It might have to do with software to hardware reading, just my theory. The battery may be new and not calibrated (or used and charged enough), so the software was trying to read it correctly. Just my theory.

Thanks for that. It's calmed down now after a month of ownership
