It stops charging at maybe 70%. Then I gotta unplug it and plug it in again, and it will continue charging, but again stop before being fully charged, so I gotta unplug and plug in again to get it fully charged.
Firmware updates has had no effect on this issue.
Also, is it normal that it loses battery while not being used? If I haven’t used it for some weeks, the battery will have gone down a lot.
