Battery life has been abysmal on my Series 6. Here's hoping.

Yeah, the battery on my Ultra has gone a little wonky the last few weeks since 9.5. Hoping this fixes whatever caused that. A reboot helped a bit, but definitely seeing more drain than I had been seeing during the day.

Yep, my Ultra will no longer run for two full days. When I first got it, it would run for three days (72 hours) before needing to be charged.

I checked the battery health on my S6 since it used to be around 40% at 10 pm and now it’s usually below 20%. The health is 98% so it must be the update.  Fingers crossed

Oof. Mine is at 83% maximum capacity. Okay… Hmm.
