I charged the battery to 100%, turned it off, left it overnight, the battery dropped to 95%. After 15 minutes, the battery is 94%?! I heard that it is not recommended to charge with a laptop or a PC, is that correct? For a few months now because my watch is draining the battery so much, I charge it like that, does this have any effect? If yes, is there any other fix? My watch is out of warranty, and the dealer quoted a replacement battery price close to the price of a new watch.
