Re: Battery life of HTC one
Here's the rules -
Voltage is force pushed by the charger.
Current (in amperes or milli-amperes) is drawn by the device.
If the device is designed to draw a maximum of 1 A, then giving it a 2 A supply changes nothing, it will only draw 1 A.
If it's designed to draw more than 1 A, then giving it more than the standard HTC charger (what crafty and all other HTC owners get) will let it charge faster.
Battery degradation is largely a function of heat and charging cycles. If it stays cool charging, then the battery lifetime isn't materially changed, regardless.
