I can confirm. To reproduce, charge the phone atleast to 90% (it will reset battery statistics) and then reboot. After a shutdown it will no longer provide updated stats.
My Phone also has this bug, after I restart the phone, then it stops update SOT. But it update the SOT after I full charge.
We have finally managed to replicate and await our devs to find out why
good, we are waiting for fix on the next software update...
this issue is still on the latest software update v193. they did not fix it.
We're still working on the fix so hopefully in the next FOTA
Look at the screen shot the battery stats for sot is showing zero I restarted the mobile at 98% and used till 81% still the stats shows zero screen on time
This is a known bug. Asus devs are aware of it and it will be fixed in future updates.
Ok thanks for the reply
I have two zenfone 6, one silver 6/128gb and a black 8gb/256gb and this bug is not present on the 256gb version.
I have 256GB version and I have it.
This issue won't happen every time so it's probably just a coincidence that you're not seeing it on your 256GB version. Our R&D are still investigating the root cause but I'm pretty sure it will be fixed in Android Q regardless.
