lol... it's a feature! Battery Health Monitoring as hardware implementation... amazing!
Q: How do I know my Apple Watch Battery needs servicing?
A: It will pop open and show you the battery
Seriously... anything that has that short battery life will accumulate a lot of cycles in a short time. Typically, Lithium Cobalt Oxide (commonly known as LCO) are done after 500-1000 cycles. Other chemistry, most notably Lithium NMC, can double that and is more safe in operation and can deal better with high currents (quick charge!).
Yet, even Boeing was stupid enough to choose LCO over safer technology (in the aviation one could expect LFP), which grounded the entire 787 fleet. The Note 7 disaster was just another good example why use of LCO should be discontinued preferably asap. The good news here is, that thanks to Tesla and other e-car manufacturers (who realize that LCO is not state of the art), other chemistry is more widely used.
