I've been having a problem with my battery recently.
When its around 10% the phone shuts down, if I turn it on then it shows 0%.
I've used Battery Calibrator but the same thing is happening.
Is this common or can I fix it some how?
Ditto! Think it started happening after I tried a dodgy Chinese travel charger thing. Have stopped using it now, but the problem remains. Funny thing is, if you let it die, then start charging it again, wait for it to get to 20% or so, then unplug it, it'll discharge all the way down to 0%. But if you let it fully charge to 100%, it won't.
And no, it's definitely not normal for it to shut down at 10-15%.
