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.

I noticed significant improvement with last .60 update. Last few days it used less than 0,5%/h screen off and less than 10% mobile in standby per day. I also disabled google auto backup few day ago, idk if that had any impact, or it was just update.

The .60 update does address certain scenarios causing more standy drain than expected - but whether or not it improves everyone's situation is hard to say as that is still highly dependent on how the device is actually being used (which apps, which features, which network, which signal condition, which brightness and so on).

I did some more testing.
I can confirm @shazadz's point, disabling 4G network made the battery last for almost 2 days (so basically double the time compared to the standard settings). So 4G management needs to be fixed for sure :


But there's still something broken in the overall behaviour. At the and of the charging cycle, cell standby drained almost 50% of the whole charge, with big drops happening at night :



Indeed, i had "scheduled power saving" feature enabled to work from 2:00AM to 6:59AM, so i suspect it to be the possible reason of the night drops (meh, it is supposed to save battery, not savage drain) :



Other than that, i can't find any other processes or applications doing something different at night in particular, so the behaviour is still unclear.
I'll do one more test disabling night power saving and see what happens.
More infos/suggestions are always welcome.

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.
