I've had an iPhone 5s for a couple of months and think the battery is knackered already
. This is my third or fourth iPhone and am always careful about charging properly, I've had a couple of my phones for two years each with no major battery problems. I unplugged this phone at about 3am today as it was fully charged and by 6 was on 60% charge - with no apps in the background, low screen brightness and location services/Siri off. The only thing I can think of is that I did a few partial charges last week from moving my phone about as it was charging, surely this shouldn't be enough to completely break a phone battery though? Is there anything I can do or am I going to have to send it away for a replacement battery?
