Cell Standby battery drain

[Salvatore]

Hi,
i'm experiencing seriuos issue about battery, it's being constantly drained by cell standby with abnormal values. It's actually draining more than the display, that's unacceptable.
Can you please provide a fix/solution ?
Zenfone 8 - hardware and software details attached.

How exactly to disable this function with permanent connection to the mobile network?

Thanks!

Generally, we try to isolate real apples to apples conditions to try and figure out if there is an issue in so far related to the "code" or if there is an issue related to network, or an issue related something else.

For example, is it mainly a gap on representation ? I,e, what gets shown as "mobile network standby" , and what does not. What attributes to it, and if there is a difference between ASUS and Google Pixel.

What was the overall usage like. Was it on standby a lot - does the Pixel 3 drop mobile connection when it is on Wifi (ZF8 has default that it keeps the mobile connection for faster switching, it can be turned off in Developer Options).

To debug further, a good starting point would be if you charged both devices fully, and then end of the day, post the 'Battery stats' page on both phones - if you can, and we can try to deduce more information from there.

Thank you!

So this one:

I can answer immediately - both phones had "Mobile data always active" turned on in the developer options. I will now turn it off for both devices and try to get the full charge to end of the day comparison for you ASAP (hopefully tomorrow) .

@CH_ASUS when I think of it, I can just share today's usage as that is what happened (only thing is that zenfone was charged to 80% as I Have limited it to 80% max charge and Pixel was charged before I went to sleep).

Screenshot in English is the Zenfone 8 and the other one (Bosnian) is Pixel 3. Does this help you, or you would still need more?

I just also noticed there is "Android System" and Android OS on the Zenfone accounting to 10% while pixel only has "Android System" with 3%

13% in 5h is a lot. Something is wrong. Mine uses under 10% in one day, 4G, data on.

So mine just used 2.7% in 56 mins for mobile network standby. I have set it to 2g/3g only before taking it off the charger. Not sure what is happening to be honest.
