FR 955 Series Battery Drain after 12.23 sw (possibly due to BT connection)

Tommy
over 2 years ago

After installing 12.23, rebooting several times then charging my watch I now see a battery drain of ~5% per hour without any activities. Which is to say my watch will last less than a day if charged 100% and I don’t record any gps activities. I’m on iPhone 12 Pro (iOS 16)

The watch also seems to run significantly slower, hanging between screens. 

If you already installed it and found this post, I’m sorry. Upvote or comment and hopefully Garmin will fix this soon. If you haven’t installed it yet, don’t. 

UPDATE: 

There are currently two options to prevent this issue: 1) disable Bluetooth and manually sync via WiFi. 2) disable Strava live segments in Garmin Connect by going to settings>training>segments> click the 3 dots and switch to garmin segments. This is likely why not all users are seeing the battery drain issue.

    And the update was successful and you have really 12.23? I was thinking if it would still trying to transfer the update via BT, that's slow and could eat battery.

    Yes. 12.23. Updated yesterday after I connected it with my laptop with Garmin express.

    I wasn't asking from you, but the OP, who solved the problem by disabling BT. You didn't even have problems so why would we speculate that the update failed on you? 

    I have 12.23 also, without any battery issues (currently).

    Ah sorry. Thought that you suggested that maybe the persons who didn't have an issue maybe didn't update. 

    My bad.

    No more problems after restart. Not worse than 11.20.

    Ho trovato molto probabilmente il motivo per il quale si scarica più velocemente la batteria. L'orologio continua a cercare la connessione blueetooth con lo smartphone. Noto ogni minuto circa ,sul quadrante dell'orologio il simbolo della riconnessione bluetooth. Chiaro che questo ripetersi di connessione / riconnessione allo smartphone, drena la batteria precocemente.

    Prima dell'aggiornamento a 12.23 non succedeva. 

    Non riesco  a mettere il video per far vedere cosa intendo.

    yes, I have got the same problem.

    In the first night after updated into 12.23, the battery just drop 2-3%. However, it drop about 40% in the second night of sleep.

    I also find that the reason maybe the connection with Bluetooth.

    Yeah, the phone has been restarted, no change.

    Yes, I verified on the watch that it’s updated correctly to 12.23. I agree the Bluetooth sync seems to be the issue for both the battery drain and the slowness. If I disable Bluetooth everything functions as expected.

    Yeah, then not trying to transfer the firmware to the watch. No idea then what it's doing. Have you tried to sync via wifi or computer and garmin express, would it sync something big that would help situation? But probably doesn't help much, but last idea that might help.

    But there's some BT comments, so might be some issue with some phones BT and Garmin's BT.
