Overcharge protection. Function of battery or phone?

Текст:

I need to charge my battery externally. My only concern is overcharging and ruining the battery. I know there is a circuit somewhere that prevents overcharging. Is that circuit built into the battery, or is it part of the phones hardware?

Устройство:

iPhone 4S
