Battery stuck on 100%

Purchased epix pro 51mm last week. First problem was that elevation didn't record on two activities. Tried all the usual and ended up with a factory reset. Which fixed it. 

Now battery is stuck on 100%, 12 hours after a full recharge and doing a 40 minute walking activity with screen on

Had more problems with this watch in week 1 than I had with fenix 6 in 3 years. Joy
