I noticed my phone charging much faster every since I did a factory reset. I don't know if this goes for everyone, but that was definitely my case. My phone from empty needed close to 6hrs to charge, and that was needed right out of the box, and after a couple power cycles. Now it needs no more than 3hrs. Maybe something you guys can consider before getting another phone.
