Battery consumption: initial observations?

sounds like you've done all the homework for them. hope they can figure this out as i anecdotally think this is something related to battery drain issues people experienced with the 945LTE. thanks for keeping us posted.

i had the issue with gps multiband, no sensors. i dont have the issue every time tho. sometimes its fine even if i dont restart, but as soon as i notice battery dropping fast a restart fixes it.

it may also be that it builds up over time if that makes sense, like a thing slowly using more and more battery.

Ive lost today 7% in all+multiband mode with music on 45mins run(~9% per hour), which i find nice. But while hiking in the same mode without music im always getting avg 6.5%/hour, which is not giving promised 20hrs for all+multiband mode. Could navigation mode on be the cause of additional usage (should be ~5%/hour imo) ? 

Charged lunchtime, one 30 min run with all GPS and music and 12 hours on lost 10% down to 90%

interesting data points. i've only done one Multiband activity, but i saw a drop of 6% for a 70 minute run. that could easily fit into the realm of your data (given the lack of precision of what is reported by the watch). i wonder if anyone out there has used DC Rainmaker's analyzer to see burn rates. i keep saying i should check it out, but my frugality keeps me doing it for just a simple exercise in curiosity.

for All Satellites mode, i have much more data and i'm getting consistently 3% use for 60-70minute runs. (never seen 4%), so that to me is quite pleasing and seemingly even better than spec (31 hours). i've gotten that sort of consumption both with and without a Garmin HRM chest strap (ie, OHR for the times without it).

your suspicion of navigation seems like a reasonable hypothesis. if i recall in reading reviews of the 945LTE, people have shown enhanced battery drain when displaying the map. are you showing the map when you are hiking?

Same issue for me. Large battery losses through the day and overnight. For both my watch and my Stryd pod. Haven't charged both so much since I got them (been using Stryd since 2017 with 935-945 and now 955 - on my second pod).

Hopefully updates come out soon to fix issue rather than me having to remember to disconnect / reconnect Stryd.

Just to add to this again. 

Charged mine to 100% on Friday. 

Did a 50 minute walk with Polar Verity HR monitor connected on Saturday
60 minute run with Garmin HRM Pro / Stryd / Tempe connected on Sunday
2 x 20 minute commutes on my bike Monday with Garmin speed / cadence sensors connected
3 runs last night, including 65 minute run (WU / CD), with HRM Pro / Stryd connected. 

60% battery this morning as of waking up, and I've not restarted the device since the initial update to 10.10 firmware on the date of purchase 2 weeks ago. 

I was thinking it may have been the addition of the field for Stryd. My batter drain issue seemed to start around the same time. I am going to drop it and see if makes a difference. 

I started the day with the watch at about 90%. I did a 2.5 hour run with full multi-band GPS, course routing and per-second logging, with a no-name Chinese HRM strap (Ant+). Finished the run with the battery about 85%. Even though it was sunny, solar intensity probably only averaged about 15-20% over the whole session (according to the Solar Intensity Logger IQ app).

This is exactly what I'd hoped for in this watch, and a major step up from the battery life of my Vivoactive3, which I had to charge every other day, and which struggled to last for any run over 2.5 hours without having everything "stock" and Bluetooth turned off.

Hmm, 3%/hour with all satellites sounds good. Got to make some runs in that mode, have been using all+multiband so far. When hiking - yes, i have a map with navi open most of the time. Maybe thats the cause :f
