I have purchased an apple watch series 4.
I noticed a problem with charging since I bought it.
on charger, the charging process is always interrupted and restarted.
I wish you watch the video for what is happening to it in the link below where I uploaded it.
one more issue, it is charging very slowly. it may take 15-20 hours on charger to be fully charged.
I tried the force restart and cleaning the watch back with no results.
