Mine went from 100% to 0% in 3 hours. Lots of other people reporting similar issues. Hopefully they issue a fix soon.

100% charged battery and after 9h still had 80%

Mine is also terrible. I took my watch off the charger around 5 am and at some point between them and 7am it died. Charged it again for a couple of hours to get to just 46%. It’s at home on the charger now, as there’s no point in wearing it like this.

Mine drained shortly after the upgrade but after 2 days it was back to normal. I figured it was just behind the scenes things happening associated with the upgrade.

Same here, S7 45mm

I’m still at 80% after updating about 12 hours ago

Weird. Mine is fine. No better/worse than before.

Mine is fine same battery life as before the update, try resetting and reconnecting it

Mine seems better since the update. 94% - 39% over 24 hours. AWU1.

yeah I’m skipping this update fo sure

Update on my situation, went to the Apple Store today, they unpaired the watch, cleared it, ran diagnostics, all that. They told me to come back if it isn’t fixed. Well it’s not fixed, still won’t charge past 78%, and went from that to 5% in under 3 hours. And man, I don’t feel like driving an hour back to the mall this weekend. Way to go, 10/10 update

Hmmmm odd. Mine updated this morning at 8:30. Went from 100% to 77% as of 10:14pm. No battery issues so far

I was gonna download but I didn’t thank god

Same here Ultra 1 empty twice in an 18 hour period.

I reached out to Apple Support as I have the same issue, and they told me they didn’t receive any reports and wouldn’t escalate it to their Engineers.
