normal drain or battery problem?

hi all, does anyone know an app/widget to figure out what drains the forerunner battery?


my 965 has power saving on, no AOD, no spO2, no notifications, no wifi, no bt, about 50' run per day, only active ohr consumes about 0.813%/h.

I've emailed support twice but they didn't reply. the estimates displayed on the 965 are in line with what Garmin stated, but the consumption then actually is much faster (about 5 days on a full charge), i don't know what to do anymore, the consumption is regular

Thank you

    My 965 (no aod, no spo2, bt, notifications) usage in gps mode is quite high, but in normal watch mode alright.  (Was on holiday last 3 weeks and didn’t use gps much. Batterylife is really good) 

    With my previous 935, battery usage in gps mode suddenly increased when galileo support was introduced. Testing with different modes (gps only, gps/glonass or gps/galileoj didn’t ake any difference for battery usage or accuracy, while it should, at least for battery usage. So I suspect there was a bug with selecting gps settings. 

    Now my watch is on sat iq setting. But there is no way to see which  gps setting is actually used. It might be unnecessarily in multiband mode all the time.

    I think there is a issue with the software of the watch it's so unstable, try turning off the Bluetooth on the watch for 1min and turn back on maybe this is a temporary fix

    Thanks, my bt is already disabled. As soon as I have a few minutes I will try to do a system reset

    I observed the 965 battery has drain faster after new firmware 16.17 update, usually it would last 10 days with 300 min running/week , power saving off, no AOD, no spO2, no notification, wifi and bt on.   Now my battery last about 7-8 days.  Is that normal?

    the 16.17 software is a total mess it's like a beta, they mess up many things even when connecting to the pc, the battery is draining...

    I've noticed no change since 16.17 in battery usage.  I'm about .800% with power saving off, AOD (low brightness), no spO2, notifications/wifi/bt on with about 400-500 minutes of GPS use per week.
