I haven't had this problem with my NOKIA 3 - does it charge once it's off? Did you contact customer support?
Do you have the right charger and correct one or is this via a USB charger as I have notice this with some chargers via USB in cars,does your phone actually go off or just have black screen?? You can press the keys volume up/down and see if you can hear sound. If its switched off you can simply press the volume up and power key in until you get a vibration and see the android logo come back on screen and let go.
Yes I had this common enough problem with my Nokia 3. However, since upgrading to Android Oreo beta the problem has not occurred again. Prior to upgrading from 7.1.1, I was getting the Nokia 3 powering itself off at least twice a day and always when I plugged in the USB charger cable regardless of the actual battery charge.
I used the OTA upgrade from 7.1.1 to Oreo 8.0 beta 15 days ago and have been unable to reproduce the problem since then.
I also buy the Nokia 3 phone almost 1 month ago. And when I update the phone software it's running very slow and performance got low. I think we should go to the nearest service center of the Nokia.
Have same issue :((
Had issue with 7.1 , after OTA update to Oreo 8.0 ....same issue
Every time when I switch phone for charging(if is in screensaver mode or "screen off" mode ) phone switch off at once.
If, I switch it for charging with "screen on" mode, no problem
New Phone (new from repair) no problem . and with May Patch it switch off when plug in
