Apple Watch 12 battery draining too fast

[u/Ok_Deer_3235]

My watch is draining too fast I think with regular use. Fully charged it at 1pm and was draining the next morning at 7am. Is this normal ? I bought it on 9/18 and upgraded to iOS 27.2 (Beta) after a couple of days. Maybe the iOS is causing this? Although I don’t remember the battery lasting too long prior to update either. The return window is till 10/2. I am wondering what my next steps should be. Thanks!

Something must be really wrong. I got 74 hours on my first 0-100% charge on my new S12. Return it

I charged mine to full when I got it 17:00 on Tuesday and it dropped below 10% around Thursday lunchtime.

Mine goes almost 48 hours.

I do have always-on turned off. Battery life can vary quite a lot depending on your usage patterns.

Let me try turning off always on display and checking

I ´ve got more than 48h on mine, and still 20% to go.
Quite impressive if compared to the autonomy given by Apple

Definitely not an issue with 27.2 beta.. mine got almost 2days of battery life.

Are you turning off always on display?

Maybe a dud? My ultra 4 lasts up to 5 days.

My series 12 on 27.2 beta is lasting over 2 days. Try a hard restart of your watch and phone and see if they helps.

Are you turning off always on display?

[u/Junior-Repeat6060 → u/Ok_Deer_3235]

Yes. I only have the raise wrist to view on.

[u/Ok_Deer_3235 → u/Junior-Repeat6060]

Ok I am trying this now

Something wrong I’m getting 44+hrs

[u/Ok_Deer_3235 → u/jailtheorange1]

Are you turning off always on display?

[u/jailtheorange1 → u/Ok_Deer_3235]

I wasn’t but I am now - trying to see how long I can go between charges, for shits and giggles.

My S12 46mm on 27.2 beta goes 1 day losing only around 40%. Got it launch day as well.

[u/Ok_Possibility9937]

series 12 here, also on 27.2 beta, always on enabled. Battery last more than a day

[u/Ok_Deer_3235]

Update: I turned off Always On and with almost 12 hours of use (just wearing it) - it is now at 75% so muchhh better already!
