After installing watchOS 11 on my Series 8 watch the battery life has been very poor. Hasn't been 12 hours yet since I did it and I can already tell that there's an issue. Overnight the watch will use about 10% of battery. Last night it used over 30% and used another 5% while I was up for about 45 minutes.

Apple Watch Series 8, watchOS 11
I think I have a solution for this:
I have a Series 8. Battery health reports 80% capacity (after about 2 years).
Following my upgrade to watchOS 11.01, I was running out of power around 12-13 hours into the day. This was even worse if I had a workout (I sometimes train for 3 hours in a single day.) On any regular day, my battery was down to 50% by lunch.
I did the following this week,
which has improved things a lot:
I have done this in the past and it seems to clear up a lot of issues, particularly with power management.
Yesterday, with no workouts, I finished the day with about 25% left (at 14-15 hours). So far today, I am at 50% after 8 hours and one workout. I have another workout for two hours this evening, but I should make it to 16 hours without going to low power mode, if I’m not mistaken.
So - unpair and re-pair, loading from the backup!
You should find the setting on the Apple Watch itself.
On the watch app it’s under privacy and labeled Music detection.
(I’m currently using Apple Watch 10)
On the watch, open Settings -> Smart Stack -> Live Activities
Let Apple know directly about this issue by using the Feedback link, this is the only way to reach them.
It varies with how many apps, emails, texts, songs, photos and other files and media stored on your Apple Watch. Much of syncing and indexing is done at night or when the Watch is on the charger. Depending on your usage patterns, it may not have a lot of time each day to complete its tasks.
I just turned that off so I'll see if it helps.
But after the first few days after the new watchOS, the battery drain got a little bit better, but it was still draining more that it did before the watchOS update. I if the Live Activities is playing a part in this. It's OFF now. Let's see what happens.
My iWatch Ultra 1 normally has a battery drain over 2 days. After turning off Live Activities and turning off all but three apps for notifications, unpairing my watch twice, waking the iwatch by touch only and reducing brightness to its lowest setting, battery is discharging a tiny bit slower. Still very unacceptable. My iWatch battery health after Apple Store ran diagnostics is 93%.
This was yesterday. None of the Salt Lake City, City Creek store techies were even aware there was an issue. LoL
Must of been a memo from Apple HQ to deny everything related to the iWatch iOS update 11.0 being the culprit for such a massive battery drain.
Oh well… waiting for update.
You Watch contains a lithium ion battery. Apple batteries and any other product containing lithium ion batteries will perform similarly straight out of the box.
Lithium batteries go through a conditioning practice or curve during its first few charge cycles. This is normal. After 3 to 7 charge cycles the battery will stabilize and deliver a more expected experience.

Just spent close to an hour troubleshooting with Apple support. No resolution.
Ive had all notifications disabled, no Bluetooth accessories, live activities disabled, always on disabled, and my ultra 2 is dying in under 18 hours with no usage.
Yeah… I opened a ticket with them as well just to get it on the books in the event that my watch battery goes south prematurely then I can point to this 💩show and say "Hey! THIS is why my Series 9 Battery failed early and now I want a new one, on your dime!" 😉
We don't know what this might be doing to the health of our batteries over the long-term! My Series 9 battery health is down to 94% from a previous 98% only a few weeks ago. Coincidence? I seriously don't know. But I'll definitely be keeping my eye on my battery health now more than I would've before.
In terms of my Phone session with Apple SUPPORT, they did run a battery diagnostic on my watch while I was on the phone with them and it all came back normal. Apparently their testing software can't find any specific causes for a battery draining Improperly or not. They can just check to see if it's physically functioning within spec, which apparently mine was at the time.
This is a recurring issue with the update 11.0.1. Upon its release, it was supposed to fix the , i.e., draining battery, and the watch restarting on a frequent basis. After four days, you think that the problem is solved, but it is not. To make matters worse the support from Apple is Zero. So, I guess, we’re gonna have to wait for a patch from Apple, and turn the AW off in the meantime. It is really ridiculous to say the least.
Which additional apps did you use during the workout, did you use the Apple Workout app to record your run?
Keep on sending a detailed feedback about this issue, this is the only way to reach Apple directly.
You have a beta version if you’ve had it more than a week. Please update you Apple Watch to the full version of the Apple Watch OS 11 just released yesterday. Beta version may deliberately decrease and increase performance in specific areas and cannot be used for evaluating battery capacity/life.
No seriously, like I noticed over night my battery about 30% too (Apple Watch SE) (when it typically would only go down 4-5% while wearing it sleeping) and whenever I would go to school on a full charge, I would come home with out 50-60% (school lasting from 8-3, coming home at 4) however I noticed today, my battery was at 24% and I went to school on a full charge. Thought it was just me over the weekend, but no, the battery is draining extremely fast.
I have the Apple watch SE (2nd Generation) and experienced the same issue with battery drain, which I noticed immediately after installing the watch OS 11 update. Watch OS 11 now requires that you have Bluetooth enabled in addition with WiFi. And you can no longer use the watch app on your phone without having both Bluetooth and WiFi enabled. Bluetooth constantly searches for other Bluetooth devices to connect to, which results in battery drain on the watch and phone. But most concerning, is the safety vulnerability with having Bluetooth always on. Having Bluetooth on posses a greater risk of your device(s) being hacked. My watch worked just fine with only WiFi or cellular data before the watch OS 11 update and the watch battery lasted almost two days and my iPhone's battery was good. For the above reasons, I have stopped wearing my Apple Watch and returned to a traditional watch. I'm selling my Apple Watch.
Bluetooth does not search constantly for devices to connect. Only if you open the Bluetooth settings on the device, it will scan for other devices it can connect to. As soon as you close the Bluetooth settings, it will no longer look for other Bluetooth devices.
Bluetooth is also used between the watch and the iPhone to sync data, if no Wi-Fi network is available.

Ultra 2 owner here. I’ve tried everything to restore the battery life I had before the 11.0 update. Watch would last 2-3 days before, I’m barely getting a full day now, 18 hours maybe. Its horrible, Apple this needs attention.
