Hard to say, but after 6 months my AW7’s battery health is still at 100%. With AOD on I’m typically at around 45-50% by 7pm after cca. 12h use. Btw, usually I take it off the charger around 10-11pm the previous night and just let it stay on my night stand before putting it on my wrist in the morning, so basically that’s almost 1 whole day off the charger.
It certainly sounds like it may be sorted then. Mine had lost about 6% health by the 6 month mark. I do charge overnight though as that suits my routine. The battery is supposed to stop charging once full so that shouldn’t make any difference. When I get a series 8 i’ll be monitoring this again.
