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

After last November update (32.2050.2050.34) I had even more restarts. I think I'm gonna sell the device. Looks like company doesn't care enough to just grab a phone and assign a dev to solve it. Really crappy attitude to an issue this magnitude with so much customers complaints. I hope everyone here opened a complain to Asus customer service.

I confirm that with the latest update 2050.34 there have been other restarts however Android 13 is coming in December 2022, the totally rewritten software I am sure will solve the problem, and in the meantime it is sufficient to remove the security PIN from the SIM to have no real disservice as the smartphone restarts completely and is fully operational again in a minute.

Having the same issues. Increased with the last security update.

I'm trying to get logs to share in case.

OK so as someone had posted in another post I started that I might have this issue too.
Bought this phone only 5 days ago. In Australia and each morning I'm forced to use a swipe pattern to unlock instead of my usual Fingerprint

Asus if this is a hardware issue how can I replicate it so I can get a refund because I can't leave it in the store for an hour in the hope it would restart by itself.
