Someone locked my other thread, so reopening it here.

I’m on SW 7.8 and have noticed bad battery life over the past few weeks.
I’m suddenly down to ~70% drop in less than 2 days and sometimes the battery will drop 30% in just a couple of hours and then level off.
Charging also seems way too fast, which makes me wonder if battery capacity is bad.
Battery drop with GPS activities seems normal. It’s outside of activities where it goes quickly.

A soft reset helps temporarily, but it comes back. Just charged mine two days ago. It charged from 15% to 100% in about 30 minutes and then proceeded to drain 50% over the next 24 hours.
I think the battery capacity reporting is bad. It's a little better if I leave it on the charger for a few hours. Will only drain about 20% a day, which is in line with the stated 5-day battery life
