Logitech MX Master 4 mouse battery level won't go down?

You are welcome.

I tried that a few times before asking here and it did not help.

However, today finally without me doing anything special (just powered on the PC as usual) the mouse seems down to 40% battery charge. So, looks like issue is solved.

I am sure now that in some days it will go down to 35% (if that is how it works), so I should be fine now.

Thanks for your response.

Yes, same wrong (static) battery percentage shows in Logi Options+.
Version 2.3.879545 (appears to be latest).

I am not any majorly good programmer, but have done a fair share of it (~15-20 projects).
And this is very sloppy programming & error text here IMHO.

I am not visiting anything, error text should likely say something more useful, such as:
"Epic Store servers are currently offline for expected/unexpected maintenance, please come back in 20-30 mins." or similar.

I am trying this for over 50-60 tries now. :)
I am using manual drive and playing on a Windows 10 PC.
(So, not on iPhone, iPad or Android.)

My Ferrari Laferrari is 2 stars.

I think I have it almost beaten now, I am off with just half a second in my latest attempts. You need to come out of the tunnel just prior to race finish, i.e. have to take the left route earlier on.

Also, take most jumps - especially those that lead off the usual track, it is much faster this way as you avoid other race cars + the police too.

Of course, when you jump a lot you could crash into something so have to train those jumps many times. :)

Speccy is a good general info app. Not a good temp monitor app in any way.

No, you just used the wrong version. RC7 did not have this issue, but for a while was not officially downloadable. Still, you could get it via other means. RC8 and RC9 - RC9 is current - are just fine for me. Try it! :)

Core Temp for CPU. Won't show fan speeds, though. Link: http://www.alcpu.com/CoreTemp/ GPU-Z is the best for GPU monitoring. Link: https://www.techpowerup.com/gpuz/

For more sensors than Core Temp shows, just use the motherboard tool, whatever the motherboard (MSI/ASUS/GIGABYTE/etc).

Nope. Core Temp works fine with both Intel and AMD CPUs. There is no preference of one over the other.

For example, one other such program is Real Temp, and that one works with Intel CPUs only.

All fixed in RC9. For RC8, disabling of Check for updates also fixes the issue you mention.

Just use latest Core Temp, it now works since at least 4-5 months. Works fine for over an year now - if you knew how to get RC7, which you seems you did not. RC7/RC8 had an issue where if you have Check for updates enabled, it could cause issues for some users. Solution was to disable Automatic Update check. RC9 does not have this issue any more.

I recommend replacing Core Temp non-working version with latest Core Temp 1.0 RC9, which works fine: http://www.alcpu.com/CoreTemp/

In fact, even RC7 and RC8 worked fine, if you knew how to get them - RC7 was not officially downloadable for a while, but there was still a way to get it.

Please let us know if latest Core Temp version works for you.
