Sudden battery drain on the S9B while lying on the shelf, and a watch face glitch
My S9B drained its battery (again) fast while lying on the shelf. It had occurred once before, a couple of months ago, under similar cirsumstances.
The watch was (and is most of the time) in power saving mode (settings->general->power saving enabled) and the battery level was at about 40-50% when I did an indoor excercise (one hour, cross-training sports mode, GPS off) 2 days ago, in the evening. The watch is still in power saving mode, the activity hasn’t been synced yet to the Suunto app. Yesterday evening I accidentally bumped the watch, so it woke up and alerted me that the battery level was 3%. I put the watch on charge and charged up to 94%. It was still on the charger when I looked at it to check the battery charge and noticed this glitch on the watch face (look at the elevation field):https://www.dropbox.com/s/dxhlfj018zwb5d1/VID_20210114_192604.mp4?dl=0
Since yesterday evening the battery level dropped from 94% to 59% within 13 hours while lying on the shelf and power saving enabled. The watch face glitch is gone though.
I’m guessing that it might be a bug related to the power saving mode being enabled and recording activities while the phone is within bluetooth range. As during activity power saving is disabled, sync may be triggered upon stopping the activity, but power saving is activated as soon after the activity is stopped, and probably the watch, or a peripheral remains in a higher power state than normal.
@Dimitrios-Kanellopoulos what do you think?
Quite ironic that a power saving mode can cause excessive battery drain
@halajos I have a feeling that the new watchfaces are more power hungry than the “originals” of the watch. Using the new watchfaces, when they were introduced, I had a similar experience to yours after some weeks of using them (no saving power mode activated) but then I did a soft reset and returned to an original watchface and came the last firmware update, so I can’t tell if was a one time thing or something related to the new watch faces/firmware where they were introduced. My feeling is that with the new watchfaces I loose between 1.5/3 days per battery cycle with my use of the watch, but this is a feeling.
I would use the new watchfaces and test more but I do not like that they miss some battery information in some situations.
@cosmecosta I’ve been using the same (the one with the baro trend) watch face since it was introduced. The battery drain I experienced yesterday happened to me only twice.
I think this watch face specifically cause some problem because there is on other topic where someone make bug is watch and he use this watchface to.
Personnaly i use basic watch (the one with time in big and me watch last me one week.
I use it for musculation with HR, walking, cycling with HR and GPS (endurance, ok or precise)
I use it to for me sleep time and the daily HR. I don’t use saving battery.
My luminosity is at 15%
and all thing turn on dark theme.
