In general do chargers with higher amps/watts and charge fast hurt phone batteries?
Thanks for the help.

Dear Friend
It it does not hurt the battery, will it hurt the Phone.
It can't hurt the phone, either. If something is somehow broken and the voltage is too high it could hurt the phone, but that's true with any charger and a very rare occurrence. The phone (and charger) only pull as much current as they need. The higher current from the wall outlet is not pushed into the charger and the higher current from the charger is not pushed into the phone.Dear Friend

Most USB 2.0 ports will supply up to 500mA and are "charging" USB ports. They're only required to supply up to 100mA (non-charging port), but I haven't run across one on a PC or laptop that won't do at least 500mA. My guess is it's mostly low power, mobile devices that don't give "charging" ports. Anything that's USB compliant won't damage the 100mA ports because they'll correctly negotiate for supply current (i.e. they'll ask for 500mA but not get it) even if they normally charge at 500mA on a USB port.If you're using a USB 2.0 port to charge, it's limited to 100mA, or 0.10 Amps, so that's all the phone can draw.
