I've had my One X for 11 months and now the battery holds a charge for only 12 hours with little or no use.
Typical use up to then has been moderate and I'd usually get an average of a day and a half per charge. I always let it run down to below 20 percent before fully charging it.
I thought that maybe a particular app was running in the background and sucking the battery dry, but all seems normal.
So, my question is... is the battery stuffed, and if so how much of a drama is it to get replaced? As my phone is nearly out of warranty, can I get a battery and do it myself?
