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

Yeah well asking for a pin or swipe each day after long sleep is kinda annoying or they should give us a option to change it

If you have smart lock configured, that's normal behavior. And it probably is too if you have another security method.

Writing it down, I noticed some things that do coincide and that is definitely one of them.

I had similar issue. The faceunlock is responsible for it.
Try to turn it off. Should help.

that could be a sign of the issue, have you checked the "up time" (under settings/about phone/status ) immediately after it asks for the pattern/pin? what does it show?
Also, have you checked the "battery usage" graph, what does it look like?
