Battery drain on firmware 10.44 and iOS 16.2?

Since the firmware update to 10.44 and iOS update to 16.2 on my iPhone 12 Pro, my watch’s battery drains much faster. Normally I would get 10-11 days until battery percentage was 10%, but now it lasted only 7 days. And always on and PulseOx are off. When battery is 100% watch indicates a battery life of 16 days, which is what it is since I started using the watch in August this year.

  • Not seeing it. I’m getting well over 7 days with AOD on and Pulse Ox Off. If you’ve had it through major firmware updates, a factory reset may help.

  • No. I have it turned off (by default). I’d never seen that option.

  • I agree. I’ve only really noticed this week but I’ve always kept everything “down” on my epix: brightness low, not on all the time, time-out after 4 seconds etc and consequently I’ve had a good 10-12 days between charges. 
    I noticed this week that it was going down like crazy. Zero within 5 days. I rechecked all settings and nothing has changed. Charged again today and i can see it predicted to runout in 4 days!!! 

    What’s going on?!?

  • I am running SW 10.44 and iOS 16.1.1 but do not recognize this battery drain. Do you use any third party apps or widget that recently have been updated. If badly written (coded) they can cause battery drain. Try also restart device and see if the hat helps. Just an attempt to try help out. 

  • The last time I was back to 10 days as it was before. I restarted the watch after I charged the battery to 100%. When I did have the issue I noticed that messages on my watch were delivered several seconds after they were delivered on my phone. That problem disappeared after the reboot. Maybe a combination of the firmware update of the watch and iOS upgrade caused some issues and a restart of the watch fixed it. I am using all stock watchfaces, widgets, apps and data fields, so I think I can rule out any issues caused by them.

  • Thanks. Only 3rd party widget I have, ironically, is battery graph but I’ve had that pretty much since I had the watch and it’s never affected battery life. I’ve had 10 days plus with it. 
    i can’t understand why I’m suddenly losing 25% a day. I don’t even have text messages through to my watch etc. 

    how do I restart? Do I lose data or info and have to set things back up?

    Thanks for any advice

  • A restart is simple a turn on and turn off operation. You will not lose any data from doing that. See this video (https://youtu.be/M4Pp6pDs2bg) for how to do a restart; the video shows how to do the restart on a Fenix but it is exactly the same for Epix

    you can also try to temporarily uninstall all 3rd party widgets including any 3rd party watch face and see if that helps

    sometimes it can happen that watch itself or an App or widget get stuck in a bad state and e.g., do not enter low power mode when not actively used. A restart can then help in which case watch ends all ongoing processes and start up fresh again with no bad state unless you get there again due to e.g., a Bug or something else

    A reset on the other hand is something else in which you can restore the settings or the watch to its original state as it was when you first bought it; I.e., a factory reset. If nothing else helps you can try to do a factory reset. Be aware though that if you do this then you will lose data. See this video for more info. https://youtu.be/9XyQ3gkjrgo

  • Thanks for the tips but nothing working. Only charged yesterday and due to run out in 3 days. Not the end of the world just puzzled why it’s suddenly draining twice as fast as before.

    If you hear anything or know a way to escalate to Garmin to look into further, please let me know 

    thanks again 

  • Same issue on the 6x models, people tried everything to fix and narrowed it down to recent 24.10 firmwear update as the possible reason, garmin says they are looking into it but 2 beta releases after that one have same issue, i'm losing 25% a day also and turning off everything, resetting watch, disabling everything didn't help, losing 10% a night without touching the thing is not right
