FR955 Solar v15.19 random battery drain and Bluetooth problems?

Hi everyone,

I used fw v15.19 since it was released. It worked perfectly until the last few days. I have detected excessive battery consumption. I did not install anything new nor do I have extra applications installed. To give an example: I charged my FR955 Solar yesterday afternoon to 100% and early today it is already at 64%. I did not do activities in that interval, it only tracked sleep without SPO2. The battery and watch it's almost new (4 months since I bought it).

I also noticed that since the last update of the Connect app for Android I can't edit the sports modes (activities and apps) because the watch syncs correctly, but it gives an error when trying to edit these modes, like bluetooth is disconnected.

Any ideas?
Thanks!

    Sudden battery drain is a common complaint with FR955. I, personally, never experienced it on any firmware version before during my year of ownership. My watch would consume about 7% of battery per day in the smartwatch mode, and consistently last 14-15 days... Until the last weekend. Started a hike fully charged and finished the hike with over 60% of battery. Slept overnight. The watch was in the airplane mode, as well as the phone. Woke up with 30% of battery. Still lasted the hike next day but died right after.

    I have no idea what caused the sudden drain. And it seems to be about the same 30% - 35% drain overnight as in your case. No unusual drain after.

    Have you used any sensors? Turned them off after the activity & sensors scanning. Have you put the watch in the airplane mode? That, not counting SpO2, can cause the drain.

    Yes, I use it but always I put my FR in Airplane mode at night.
    It's strange, because now looks that work normal with the exception of that I can't edit modes from Connect app, but I imagine that this is a problem of the update of the last version of Connect Android app. No overnight drain, I did 8hs of activity with GPS in the last 18hs and the battery only dropped 40% counting also the 24/7 HR tracking, etc. I don't know what can be the cause.
    The only external factor that I can take in consideration is the temperature in the city that dropped more than 15 celsius degrees in one night.

    Same here, no problems until that night.

    Same problem the last two weeks. After talking in the chat I did a full reset and it seemed fine until one night that it fell from 60% to 30% in only 7 hrs without using it , so no wrist heart rate consuming any battery and with the watch in airplane mode which should be a very econo mode. Don't know what to think...

    Last night again, dropped from around 46% to 16%. Airplane mode was ON and all connections are off Disappointed
    Everyone still could edit the Activities modes of the watch from the Connect app?

    Clearly there is another reason for these drains, it must be a bug that will be hopefully fixed for all of us with the next update.

    I have a battery drain of 2% per night, HRV is on and SpO2 is on. Try not to put it in airplane mode.

    Test it like this.

    Thank you, I will try, but I don't really like the idea of sleeping with active connections on my watch In fact, that was the normal battery consumption that I had as soon as I bought the watch and tried it a few nights and also now when it "works fine" at night in airplane mode.
