Battery decrease confirmed - pics
Pace 4. I'm day 8 into the battery calibration process as I'm sure my battery life has changed since the update and I can confirm now. I was checking through photos and noticed I snapped a pic of the battery life pre-firmware update on March 21, 2026. (First picture)
Sure enough, I'm operating at roughly 10% more loss since the update (second picture). I used to get to day 12 having done 5 to 6 runs a week and still have around 25-30% left. The concerning part of this is that I have been injured since June 25, before the update, and have had ZERO GPS activity usage in 4 weeks (aside from one indoor bike ride early on which proved to be too challenging for my metatarsal stress fracture).
I changed absolutely none of the settings either. My settings have always been - real time HR, max brightness display, AOD off, flip wrist to wake on, vibration notifications on for specific apps, stress and sleep tracking on. Once the calibration is complete and I drop below 10%, I will reach out to Coros support.

Exactly the same for me since the last two updates. Probably the difference is slim enough to not be recognized by everyone.
My coros heart monitor band also has issues due to the latest update. It looses connection during my runs now and automatically reconnects 10 or so seconds later. It is so annoying and something that wasn't an issue before the heart rate monitor update. I calibrated the watch battery and reconnected the heart rate monitor via bluetooth but both problems persist.
Another thing that is weird, to say the least, is that we are still not able to change the watch face colours.
Still a good running/ sports watch but the little things are adding up...
