Sorry if I was unclear. Basically, I meant to say that for Apple Watch owners that I know personally, they're able to get through a 24-hour period, but since the watch would be dead the next day, they charge at night. Which in my opinion makes the watch essentially useless for sleep tracking unless you charge mid-day at the office or something.
Does that charging strategy have any impact on the battery's life? I know batteries are rated for a certain number of recharge cycles but I don't know enough about the technology to know if multiple partial recharges have a neutral or negative impact.
