Battery consumption: initial observations?

i know it's probably way to early to start this discussion, but i figure crowd sourcing may yield some insights. in short, after very disappointing battery use, in particular smart watch mode endurance on my 945LTE, i have been hyperaware of how much battery use my 955 Solar is using. just overnight (8-9 hours), i was surprised to see it dropped 3-4%. it may be that the battery gauge is poorly calibrated, but so far, even though one would guess it has a larger battery than the 945LTE, i'm finding consumption not very different.

on the positive side, for my one activity so far, a 70 minute run with Multiband+All satellites, i used up 6% which right on target with spec. (basically zero sun since i ran before and just as the sun was coming up).

i'd love to hear other people's impressions and experiences as some of you have had the watch (just a bit ;) ) longer.

    I have Garmin Forerunner 955 Solar and had problems with battery life, ~2% drop / hour after run with HRM Pro. To prevent that I had to restart the watch after each run.

    Last week I have updated the watch with 12.23 and the problem is gone.

    Anyone else still have problems? I’m on version 12.27, have to keep bluetooth off or else I lose 1-2% battery per hour. It’s really frustrating. I’ve tried all the usual fixes from here and Reddit.

    I have 13.22 and battery lasts max. 5 days even if I don't do any training. Wifi off, pulse-ox off, notifications off, brightness 20%. Actually notifications are off, because I can't get them to work at all.

    Same here. 1% per hour down. I tried everything(different watch faces, BT off, Wifi off, reset, …) still no improvement. Frustrating!

    I have updated the watch to Software Version 13.22 and the problem disappeared.

    Battery consumption is for the most part great. In a multiband GPS activity it drains around 5% an hour as advertised (this is regardless of whether course navigation is being used). In a timed non-GPS activity it drains around 1% an hour. During sleep it drains between 1 and 2%. Smartwatch mode seems to also be roughly in line with the advertised value.

    However, there is a battery drain bug with 13.22. I haven't been able to pinpoint what causes it but it seems to coincide with the touchscreen lag issue that a lot of people have reported. The issue will cause the battery to drain 2-3x faster in smartwatch/sleep mode.

    I am on 13.22 and I took my watch off charge at 9PM and by 2 PM the next day I have lost 10% with no activities at all. This can't be right and never used to be like this when I first got the watch a few days ago.

    Did you power off the device after your FW upgrade? if not, then it is the main reason for the increased power usage.

    I didnt do it straight away but did last week. Still draining fast.

    For me, it helps to turn on and off the activity in the indoor pool, even after the bike activity, I do this. it seems that the gps is turned off and syncing with the phone stops
