Just got my Moto X yesterday. I have it plugged in to charge now and it's warming up some. I noticed that the supplied charger is a 1.15A charger and every one of my other chargers if have and have been using are 2.1A. Should I just stick to using the stock 1.15A charger as opposed to ever using the 2.1A? I ask because this battery is non-removable obviously and I don't want to potentially damage it or shorten its life.
