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.

There is something wrong. Or with your phone, or you have really bad 4G signal and phone is using a lot of power to stay connected. My phone used 30,5% in last 4 days on 4G. 50% for less than 2 days is a lot.

@pipsss81 i agree, there is something broken somewhere. I'm afraid it's phone-related because that behaviour never happened on my Zenfone 6, same location, same 4G coverage, same network provider, same android version 😞

Latest updates.
I confirm that "scheduled power saving" was the cause of night-time cell standby battery drops. After disabling it the average drain during night was basically the same as the day-time. It is even more frustrating considering that feature was supposed to save battery, not the opposite. But meh, at least i've found the bug :

Still remains the issue about 4G network which keeps draining in standby almost double than 2G/3G. Didn't try 5G because my provider doesn't support it but i'm afraid it would be supreme disaster considering what's actually happening with 4G.
@ Asus Folks: any chances to have the 4G issue fixed by the next minor update ?

Maybe it's just a matter of presentation.

After 2,5 days since a full charge, 3,5h SOT, 1,75h of Spotify, 0,5h of Waze (quite a very light use, as i have 2 phones), i think that after all, standby "drain" is very acceptable.

Especially as the phone seems very sensitive to the networks (while at home / work i have very good coverage, i often go to remote aeras).
