Battery drain 15% per day after hard reset (v24.10)

Hi all,
My F6x pro solar battery drain 15% per day in v24.10 even after hard reset, no CIQ watchface, widget, wifi, pulseOX, bluetooth, activity.
When I charge to 100%, it shows 31d, but it drain 5d in one day. That is crazy.
I don think is battery issue because in v23.10 that was 5% per day.
I try to rollback the version to 23.10 via GUPDATE.GCD in SystemBackdate_2310 in Fenix6XPro_6XProSolar_2410.zip, I drop the file to the /GARMIN and disconnect to the PC, but nothing happened on the watch, the file disappear when I reconnect to the PC, why?
However, the Garmin express does not provide the v25.10 update, so all I can do is rollback to the pervious stable version for my watch.
By the way, the watch is 3 months old because it had memory failure in Febuary, I paid 15% cost (about USD120) and got a new one.
So, I upgrade to 24.10 from 23.10 in early May.

This happens because the clock has not been reset.
Proceed as follows:
1. make sure that the watch is not connected to the cell phone. In the watch, go to System > Software Update and turn off the automatic update.
2. turn off the watch
3. press and hold the top right and bottom right buttons and turn the watch back on.
After the first beep, release the top right button, and after the second beep, release the bottom right button.
The clock should start normally.
Now repeat your procedure, copy the Gupdate.gcd back into the Garmin folder and restart.

All previous data will be deleted, the watch will need to be re-paired and set up.

Thanks, I will try it tonight.

Do you know why my gamin express does not provide v25.10 update? It seems to be released for a long time.

Sorry, no I don't.
But it is possible to install them anyway: Download the latest firmware from the Beta section > Beta 25.91 Sideload. It contains as SystemBackdate the version 25.10.

Install 24.78, on this sw I have a battery consumption average of 0.252%/hour

I tried, but it still nothing happened.
After step 3, the watch start and I select the language and time in order to connect to the PC, then I drop the GUPDATE into the \GARMIN and unplugged it, the watch shows loading maps for 3 seconds and back to the default watchface.
What's wrong with my step?
The watch drains 21% battery in 22 hours today...

Some post had the same problem, but almost them download the wrong series file, but I actually download the F6Xprosolar.

I find that the backdate in 24.10 to 23.10 is 888 KB, but backdate to 23.00 in 23.10 is 14050 KB, is that right?

I download from https://my.hidrive.com/share/8z6g1evyp0#$/

Does someone can give me another file?

0 kvasimodoo over 2 years ago in reply to 1055716

Try uploading the 25.10 beta update and then backdate to 24.xx. That should work for you! At least it works for me. Upload a higher sw but beta, and from there you can backdate whatever you want.

Now I can go from sw 24.78 straight to sw 13.30. But as I have tried several sw from 13.30 to 25.10, the latest ones have the most battery life with the just mentioned 24.78

But the system backdate file only content previous version.

For example 24.10 only has 23.10, how can you go straight so many version?

Is the system backdate file not required to use current version? Use whatever version you want to backdate in any file?

From the page I wrote you then download any backdate and you can install it right away, but the condition is that you install a higher version first! Install for example the 25.10 beta and then download any other sw for example sw 15.20 and from there you will only use the backdate on sw 13.30 !

You don't have to use only the backdate from the folder you installed the update from! Install 25.10 beta and then download the sw that contains the backdate you want to install
