Charging Apple Watch - should I charge before full drain for long-term battery performance?

Hi I have the Apple Watch series 6. I have typically been charging my watch once it gets to below 10% battery (going through a full drain cycle). I understand that all these batteries have a limited number of battery cycles. Would it be better if I charged my watch when it gets down to, for example, 50%? Would that be better for long-term battery health?


Thanks

Li-Ion batteries DO NOT like being drained to zero. That is the fastest way to reduce your battery life.


Typical use is to charge your Apple Watch when you go to bed each night.


A partial charge is not a full charge to the battery. A full cycle is basically when the equivalent of a fully charge battery has expended that much energy. But it does not need to be all during the same discharge cycle. So you can discharge 50% and that is 1/2 a cycle, charge it, then discharge 50% again, and that makes up a full charge cycle.


So lots of smaller charge cycles are added up to create 1 charge cycles.


But you should try to avoid a deep discharge as that seriously shortens the life of your battery.
