So, I set out to see if I can try and coax more life out of the battery.
I followed these 4 steps and I appear to have more than DOUBLED my battery life — though it is still from adequate or acceptable. My ‘HR’ would literally go for ‘weeks’ without needing to be charged (and that I mean about 9-days). So, having to charge the ‘3’ every other day is NOT good. Would be a real pain if I was travelling.
The 4 Tips.
Ensure that your Vivoactive 3 firmware is at 2.60 (and NOT at 2.50). —
Recycle power, i.e., turn it off and then on, after charging it. —
Keep the screen locked as much as possible. The touch screen is very sensitive and comes on at the slightest touch. Having it locked is real important while you sleep, take a shower or wear long sleeves that might brush the screen. —
Do NOT repeatedly synch with your ‘phone’. Keeps the synchs down to 4 – 6 a day. Noticed that synching noticably drains the battery (as you watch). I guess the ‘3’ downloads more data than previous devices.
And, of course, keep the brightness down as low as you can, and ditto for the ‘time out’. Hope this helps.

I have only had my Garmin Vivoactive 3 for 6 days so it took me awhile to fully appreciate what was happening. Plus, I did have the Backlight cranked up to 40%. Though that that was the culprit. Also think I need to lock the touchscreen when I go to bed because I noticed it was coming up often while I was in bed!
I am charging it even as I write.
Googled “vivoactive 3 battery issues“. WOW. I am, by no means, alone. A lot of others experiencing the same problem. Not good.
I am on Firmware 2.60. Problem supposedly started with 2.50. 2.60 does NOT seem to have fixed it.
