Shouldn't the Switch automatically stop charging when it reaches 100%? It needs the user to manually stop it in time to prevent overcharging?
All modern chargers are using IC chips for charging. They are using dV/dt method of charging hence it will stop charging if the change of voltage over a set period of time is 0 or close to 0. Even if you try to charge at 100% it'll only overcharge for a really small or negligible period of time before stopping.
