Battery Drain since few days

Hello,

Since few days, I find that there is an abnormal battery drain. Without doing any activity and with only the heart rate and activity monitoring activated I lose 10% / day whereas before it was maximum 5% / day.Do you also have this kind of problem?

Thanks

    The specs say that the battery will hold up to two weeks in smartwatch mode. Your previous results were 14 days + 6 gps activities before recharge which is way better than the specs and nothing anyone would expect from that watch.

    I did a rough calculation and every 1 hour of gps activity is about 10 hours of smartwatch time. 6 gps activities for 1 hour each will be 60 hours of smartwatch time. The max time is 336 hours (14 days). (336-60)/24 = 11.5 days. With music it is a lot less. Music and gps will do about 34 hours of smartwatch time per hour. (336-34*6)/24 = 5.5 days.

    Garmin recommends that we charge for a full hour, specially if the watch is quite old.

    I experienced a huge battery drain last night. With 100% of battery I only powered off and on the watch. This morning the watch was dead :-O I have the last stable firmware (*). I use ActiFace as a watch face (for years, first in my 920, now on this with any issue). I disabled it in order to see the problem is there.

    (*) Actually the previous one (the previous to the one that fix the training status). I powered off/on the watch trying to solve that issue.

    My battery drain has gone back to normal after switching off auto calibration for altimeter. I'm not sure if it's related to after GPS bug on New Year.

    10% drain every day for smartwatch mode with Spo2 set to sleep only.

    4-5 days of GPS mode daily. ~2hours daily.

    I have FR945 since the end of November and I have noticed that: the percentage of the exhaust is not linear or rather it is from 100 to 30 and then a little bit faster from 29 to descend, in running activities with foot pod it consumes a little less, I loaded my Monday evening last week (5 hours of GPS activity with music and 2 without), this morning after about 235 hours I am at 21%. All disabled except activity and HR 24/24 OXpulse once a day, wifi once a day for download, GPS only run with music, RDP + HR ant + band and foot pod ble.

    I have a 4 to 5% per day, no ohr/ pulseox, no no gps, no activity tracking, no notifications, and a watchface without seconds. This was not the case 3 months ago, when I bought the watch. Oh, and I also turned auto calibration off for the altimeter.

    FR945 charged fully last Sunday, it was not used in any other capacity than as a desk clock (was not worn, no activities), totally empty this morning. Normally it lasts 14 days if unused. It also charged to 62% in 5 minutes and full in only 15, something that normally takes at least an hour. Is something off with the battery gauge? Watch 'thinks' it is empty while it is not?

    That is the same problem I am having. My watch charges too quickly and also discharges very quickly. Besides, sometimes after finishing a workout using the GPS, it recovers around 2-3% battery without connecting to a power source. It seems that the battery gauge needs calibration. I am going to discharge the watch completely and charge it again to 100% this weekend to see whether it improves.

    Every now and then i keep having a battery drain.... First seemed to be related to the big north America map that I had to deselect to offline. But still having recurring battery drains. Happens now when I don't have the watch connected to the smartphone via Bluetooth. I disconnect it every evening and night. Battery drain comes back every three weeks or so
