my series 7 apple watch keeps locking when charging making it lose battery
My series 7 apple watch has been charging fine since I got it around a month ago, however this past week its been turning on and off whilst charging causing it to not charge as fast, but now I've left it on charge a for around a day and the watch seems to go through a constant cycle, keeping it on, and making it slowly lose charge even whilst charging. I put it on charge, the red power charging signal thing comes up, it goes to black screen, then the normal clock screen, then asks for the passcode whilst charging and then repeats that, basically until I take it off of charge.
If anyone has any any reasons why it may be doing this or a solution it would be most helpful.
Apple Watch Series 7, watchOS 8
