ZenFone 9 randomly restarts

Rising Star I
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

Phone still restarts within minutes of plugging in wall adapter for charging. For some reason my 30w car charger doesn't cause the same issue. I haven't noticed any other restarts yet since update.

I have the same problem. I bought the phone 3 days ago, and i have experienced 3 random reboot during the standby of the phone. When I pick up the phone It asks me the Pin code. Please help or i'll send back the 750 € phone!!!

Please ASUS tell us what to do. Have anyone in this treat find a solution?
I have very few apps installed, and I'm using the phone lightly.
It Is something connected with the standby.

I'm getting the same issues, even after the latest update. At least once a day my phone restarts. So far it's not been that big a deal but I'm afraid of missing important emails/messages/calls because of this.
