2018 7000 series Apple Watch new battery not charging
I have a 7000 series 42mm apple watch and the battery recently pillowed-up, so I went and purchased a replacement battery from iFixit (Item code: IF308-000-1). I swapped out the battery, but I'm having troubles with charging.
Initially the battery after install was at 27%, so per the instructions I let it drain to 10% and then put it on the charger. It charged up to 100% full overnight and all seemed Ok. I wore the watch the next day and all operations seemed normal, but by the end of the day the battery was down to 27% (normally I would get two days on one charge). I placed it on the charger and this morning it is at 17% and will no longer charge up.
I have tried this battery swap twice - this is my second attempt... both had the same issue and I can't figure out what the heck is wrong.
