Battery is empty after 3 days

Salein
over 5 years ago

Hi,

I have a FR945 since last week (wednesday) I have done so far a lot of configurations and my first run on thursday. However, I thought the fast battery drop is caused by my configurations and the test of the smart watch feature during the first day, so that I have been charged my watch after about 3 days on friday evening.

However, I was sick over the weekend so that I haven't done any trainig over the weekend. On monday morning I have had about 78% battery and in the afternoon I have received a message battery 0%. I have wondered how that can be. Atfer a few minutes the watch has been switched off because of no battery. I switched on the watch and noticed then 1% atfer a few minutes it was off again.

The watch has installed firmware 2.4 based on automatic updates.

Is there anyone experiencing the same?

Thanks in advance.


Cheers,
Marcel

    I have a similar problem. I had to turn off the HR monitor so that the battery lasts a little longer. In 935, I spent 1 week doing sports every day. with 945 only 2 or 3 days.

    First thing is to check that you have Pulse Ox turned off. That is a battery hog. Have you added any third party features? If you have take then off. Get a full charge then see how it goes.

    • Disable the backlight "GESTURE" function.
    • Set backlight timeout to the minimum duration.
    • Ditch ALL third-party apps and widgets.
    • Use a watchface without seconds.
    • As others mentioned, disable all-day pulse-ox. 

    Doing the above dramatically upped my battery life.

    Most CIQ apps will have a very minimal impact on battery, with the exception being things like Spotify, where syncing playlists uses wifi and that can be a drain.  Things like DFs aren't even in memory unless you are using them in an activity.

    WF's that display lots of data will have more of an impact than those that show minimal data, but it still won't be much.

    Also, you'll see that Garmin itself uses CIQ for things like the runpower data field, and even some of the specialized apps on the MARQ, like the "Driver" app for the Driver.

    I'm not sure turning off seconds on a native WF does anything, as the screen itself still updates at something like 1hz so the other data fields and icons get updated.

    I had similarly bad (4 day) battery life when I first got the 945, but after disabling all-day PulseOx (left sleep PO enabled) and going through a couple of charge cycles I'm now getting 12 days, with about 3 hours of GPS use per week, plus a 3rd party watch face and some widgets.

    I installed a battery monitor widget to track battery life.

    Just wanted to say that I have the exact issue with the 245music, batter drains like crazy (2% per hour) even after heavy battery life maximization, as suggested by the official garmin webpage for battery life maximization.

    that's amazing battery life... Based on my battery drain in watch mode I'm able to get 8 days without any sports activity (GPS). Original 945 watch face, BT on, OHR on, pulse ox off, activity tracking on.

    What's your setup

    Nothing special, everything normal is enabled except all-day SpO2, I use the "Data Lover" watch face.

    When doing my cycle/run workouts I use an ANT+ HRM and footpod or power meter.

    I wonder then what makes your watch last 12 days including ~5 hours of GPS, while mine lasts ~8 days without any GPS use.

    Why garmin introduce option pulse ox and we can't use, because consume battery. 

    Garmin now change quality of his products, because provide option and can't be used because required charging every day jlike others smartwatch
