Hey guys I upgraded to watchOS 9.3 yesterday and noticed a lot worse battery life I’m already at 79% after about 15 hours and only used it for sleep tracking and light use, usually I’d be around 85-90% is anyone else noticing the same?

On an AWU for reference

Thanks!

I’ve noticed the same since installing it last week. I have an Ultra and before I could run 90min and still have “plenty” of battery.
Since 9.3 I’ve been in the red almost every evening when I place it on the charger. Yesterday it went from 80% to 70% for an hour of doing nothing, then to 35% after an hour run and an hour of gym. Definitely something is going on.

I’ve let it charge to 100% last night and did a couple re-boot to see if that helps.
 
Yep. Mine recharged overnight and updated itself. Today, ran out of juice at 2PM. That's crazy. It's on the charger now, I rebooted, hoping it gets better. Mine's an AW8.
 
Pre 9.3 my Ultra lived happily between 85% and 30%. This included 1 training set daily (with GPS) of between 60 and 90 minutes daily (I sometimes used headphones as well for a podcast). I wear the watch for sleep tracking as well. I was never worried and tested the watch for a 36 hour stretch (battery went down to 24% from around 80% also included the mentioned training and headphones test).

I usually charge the watch when I have a shower to about 80-85%.

I updated my watch to WatchOS 9.3 yesterday and, post update, the battery was at 78%. When I woke up this morning the watch was down to 5%. Fully recharged the watch to 100% and in 1.5 hours the watch dropped by 3%. this is while sitting at my desk, so no training session or headphone use. I bought the Ultra as the watch 7 and 8 battery life wasn't that great and now this.
 
i unplugged at 89% at 2pm, it's 12 hours later and i'm at 66%, max brightness, AOD on. so no issues for me.

Yesterday my ultra os 9.2 drain battery in around 70% to dead battery in one night , i see on battery report its drain level is stable , i dont know why , i turn off monitor sleep and testing again , everything normal again , no more drain battery dead .I upgrade 9.3 , and i feel battery so good more than 9.2 , maybe you need take a time for watch index every data
 
****. this is happening to me too. down to 13% after charging all night at 2pm. usually i have 60-70% left at this point.
 
Last time I had a battery issue after an update, I did a restore from back up and that solved the problem. Not saying it would here but it might be worth the time to do a restore.

Mine seems to be back to more or less normal after a restart and full charge. I’m almost at 5pm and I’m at 81 percent. Took the watch off the charger at 7 this morning.
 
Mine is the same today after a reboot and a full charge yesterday. Went from 80 to 50 in 6 hours of mostly doing nothing at home.… ugh 😩
 
After a simple restart of the watch (series 6) i seem to be ok as well. 100% at 6:45am when i put it on. Now i'm still at 75% after using the watch the last 7.5 hours including 45min on gps for a hike. Yesterday it had worn down to 13% with the exact same usage! Actually seems maybe a little better than usual today... hopefully smooth sailing from here.
 
It seems to have fixed itself! It must’ve just been indexing or something I’m at 69% after charging it 24 hours ago, used it for sleep tracking and just regular notifications today

I had the same problem. Usually, my ultra needs 5-6 % during sleep. With 9.3 I had 11%.
Hopefully, it's only indexing or what ever...
 
if anything 9.3 has improved battery life slightly for my Ultra.
There have been posts with every OS update nd I've experienced this a few times myself, wait a few days, reboot both watch and phone and that has resolved it for me in the past.
 
I have massive battery drain too. I don‘t know if it has started with 9.3 beta or 9.2 but I switched off EVERYTHING you can switch off on a series 7 and the battery drain is ridiculous. My watch is pretty much a second display for my iphone, I don‘t do sports or any kind of activity tracking, sleep tracking etc. The watch is pretty much a notification display in my use case, nothing else happening on the watch. I‘ve pinned it down to the sleep focus. When I enable that focus the battery drain is crazy. Overnight I lose like 35%
 
Yup. Mines been dead every evening. Used to last til i went to bed or longer. I thought my aging series 5 was dying or some thing so good to see this post…. Now if only apple was quick to fix it cus its super annoying when going out at night
 
Ahh I see why I’ve been having charging issues, I missed the new optimised charging, which seemed to enable itself when 9.3 installed.
 
I usually get about 30h on a charge. I unplug the watch at 7am at 100% and can make it slightly past noon the next day.

Since 9.3.1, the watch is dead by dinner. This is the second update that does this to me. Last time I had to setup the watch again from scratch.

I tried restoring from a backup after wiping it, it lasted one day of normal (to me) battery life and the next day it went back to going down 7-8% per hour or more.

Someone’s not doing a proper testing job at Apple.
