ZenFone 9 randomly restarts

[HelpingHand]

Hi all,
I bought an Asus ZenFone 9 from the UK online store. I started to migrate the apps from my old phone to the zf9 and once I finished I started to use my new ZenFone 9 as my main phone. However, I noticed around 3 dso that when i wentato unplug a fter charging the phone it looked as if it has been restarted. I thought it was a software update that somehow just did that so I didn't pay attention but then it repeated again and again every day since.

I started paying attention to it and started trying to disable certain features to see if that made a difference: disabled mobile data, left everything on and now I'm on airplane mode with WiFi on.

I upgraded to the latest version that was pushed some days ago hoping that it would magically solve the issue but... it didn't!

I quick Google Search revealed that sadly this issue is not that uncommon, and has already happened in the UK and Germany to other ZenFone 9 owners.

Is this a hardware problem? Is there a fix or a patch other than simply perform a factory reset and keep seeing the same issue? Can please someone from Asus look into this issue?
Plehank youase tell us some basic information before asking for help:
Model Name: ZenFone 9
Firmware Version: WW_32.2040.2040.23
Rooted or not: no
Frequency of Occurrence: every day
APP Name & APP Version (If your issue relates to the app): not related to an app
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
=================================




Scenario: use the phone as usual, leave the phone idle a few times a day, at some point, when you try to use the phone after it sat idle for some time you'll notice that it had restarted because you'll be asked to enter your password again and about/ status will show an up time of just a few minutes

Same here. It seems to have to do with the SIM cards. When idle it tends to reboot but only if it is not busy with another application such as music playing in the background or even hotspot functionality.
Interestingly, my internet used to drop once or more a day and I had to reboot the phone to get that working. After the upgrade to android 13 beta the issue disappeared. Now I'm left with the random reboots though. Worth noting that I'm using the dual SIM. Never tested whether the issue disappears by using a single SIM.

I have a single SIM card and I had a random reboot both whilst making a phone call and using YouTube. I also see it loses wi-fi connection a lot but I blamed it on my bad internet until now
