Apple watch battery drain 10.0.1 update

I have the same issue.

Now the battery is almost empty after 7-8 hours (100% to 15% in 7 hours). I used to be able to get almost 2 days of battery (including workouts). Both are rough estimates, but know I cannot get through the day any more after 10.0.1 upgrade, and that is not OK. Where can report this issue and how can I downgrade?

Watch SE, battery health 87%, watch OS 10.0.1

I’ve got an Apple Watch Series 4 and since the update OS 10 my battery drain is massive compared to the previous update! I mean as I’m writing this my battery has lost 5% already I’ve tried all the problem solving tips and nothing is working Apple needs to do something about this because it’s not right and I’m not paying hundreds of £’s for a new one

Hey there Bensrvr,

We understand you're seeing less than expected battery on your Apple Watch. We'd be happy to provide information about this.

Check to see if optimized battery charging helps improve your battery:

Kind regards.

Same problem, everything normal until 10.0.1 update. Now watch runs down to 10-20% after 16 hours. Used to be good for 30-35 hrs. right up until this update. The optimized charging setting was on before, and is on now. Apple broke something, and it's upsetting my serenity.

Now, I can't even pair my watch to my phone because of the watch heats up on the charger and doesn't compete the pairing. AAAARRRRGGGGHHHHHHHH!!!!!!!!

my Ultra, which used to last days on a charge, cannot make it 8 hours on a charge. Wonder what would happen if I used it on a dive?

My watch drains at over 10% an hour after the update. It’s been days and it’s getting worse

Series 7 updated and the battery is now draining completely in less than 3 hours. Please fix this.
