Garmin-Laurie carrying over from forums.garmin.com/.../battery-drain-v18-15
Issue persists.
Yesterday I installed v18.16, charged my watch to 100%, did a soft reset (15 seconds light). Unplugging at 8:50 (yes, local time). I started a running activity with GPS, waited for a fix and then discarded it. 18:00 (again local time, so dT 9:10), my battery is down by 4%, giving a hourly consumption of approx. 0.436% or a projected runtime of 9.54 days *IDLE*. I know battery decrease is not linear, but this is the pattern I started seeing with v18.14.
Furthermore:
- Garmin share deactivated
- WHR on
- PulseOx off
- Backlight off
- Gestures for backlight off
- Touchscreen off
- Tones off
- Incident detection indeed on
Will update accordingly after uptime of 12, 24 and 48 hours
- After 12 h -> down to 95%, 0.416% / h, 10.0 d runtime IDLE
- After 24 h -> down to 90%, 0.416% / h, 10.0 d runtime IDLE
- After 36 h -> down to 86%, 0.388% / h, 10.7 d runtime IDLE
- After 48 h -> down to 84%, interestingly just 0.15% / h in 12 h
- --- Run Activity 1:15 h, GPS, music, external HR, Stryd, down to 65%
- --- Following runtimes exclude the running activity, so bare idle runtime
- After 50 h -> down to 62%, 0.300% / h
- After 80 h -> down to 56%, 0.300% / h
- After 93 h -> down to 54%, 0.154% / h
- After 105 h -> down to 50%, 0.333% / h
*** So somehow it seems that around 36 hours post activity something happens, that lets the consumption rate go back to 0.15% / h ***
Breakdown: Charged to 100% on 04.10. 08:50. Down to 20% on 10.10. 20:00. During this period I tracked 2:15 hours of activity with GPS consuming a total of 30% charge. The remaining 155:10 hours consumed 50% charge, resulting in an average discharge rate of 0.325% / hour or 12.75 days runtime IDLE!
