If it's a good quality charger it shouldn't be feeding the battery enough power to impact its lifetime.

- JshWright 7y agoThe "charger" in this case is built into the phone, the thing we call a "charger" is really just a power supply for the actual charge controller.
- adrianmonk 7y agoA phone will charge as rapidly as it can without undue risk to the battery's longevity. But, it's still a trade-off. If you charged slower, you would decrease risk to longevity. But when you to bed, your phone doesn't know that rapid charging convenience doesn't matter. So it will still make the same trade-off. If you use a less-powerful charger, you can force it to take its time in charging.

- starky 7y agoWhile charging circuits are much smarter now, and the difference might be minimal, you want lower charging currents to minimize the amount of damage that is done to the materials in the battery. It is universal that higher charge rates cause more damage to the crystal structure that holds the lithium ions.

- starky 7y agoThat isn't a problem at all, a charging circuit will be designed to only take as much power as the device can receive.
