[14.15] Extreme battery consumption: 1,5% per hour / 36% per day

No issues my side. Did you do a soft reset after FW install?

In my 955 the battery goes very well. 

Yeah, I did, as always.

Seems fine this time, after 14.13 issue.

Since the update to 14.15 it's still OK for me. But I had never bigger problems with battery drain. 1-2 days more or less within the different versions. Have non-solar without any IQ stuff.

Do you know, aprox, the consumption per hour when in smartwatch mode with your 14.15?

Looping 24 hours after a full recharge in a couple of minutes, and I’m at 96%. No workouts today  

Native watch face, Wi-Fi disabled, gesture off, 20% backlight when lit.

Running 14.15 on Solar-version and iOS 16.3 on an iPhone 11. 

I am having the same issue on my forerunner 955 solar. My watch was at 94% yesterday at 8am. I was at office job all day. My backlight is off during day and only on gesture at night.  and oxygen Gen is off but aleep. No music and no exercise tracking. It was 84% at night time bed. I woke up at 8am it was 60%. Sitting in chair past 4 hours working it is now 48%. On previous version I was getting 12 days with everything turned on but oxygen in day. It drained 40 to 50% in one day! I also noticed the other day it was at 30% whwn I went to bed and I woke up and it was dead. Then I charged it up to the 94% mentioned above

I am loosing just a bit more over 4% a day now with 14.15, but turned touch off since the update. Watch synced twice in last 4 days (Android), unfortunately no activities, but lost 16-17% in about 94 hours. FR955 Solar, but almost without the sun exposure. Battery is good now, but I don't know what the difference would be if I have had disabled touch on some of the earlier firmwares. When I overtrain next time I will check 4 days without activity and touch enabled.:)

Additionally - I was quite surprised when I got to the peak I usually do on my route (but went from the other side this time) and the altitude was spot on, to a meter accurate without calibration. All on auto. Last time I went there was the last year. I have to repeat it to check if the barometer works fine now or it is still has mind of its own and if it differs (a lot) from time to time.
