Hi, we'd request you follow the below steps:
1. Clear system cache.
2. Try the same under safe mode:
Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode
3. If still you face the issue
factory reset your phone after taking a full backup : https://www.asus.com/support/FAQ/1006346/
4. Last option would be to visit the service center to have
a check. Locate here: https://www.asus.com/in/support/Service-Center/India

Similar issue I am facing. Battery suddenly drains and phone switches off. When we restart the phone, again battery comes up to normal percent. When I see the battery graph, it would show sharp spikes whenever this occurs.
Whenever I approach Asus for help through Twitter or anything, they simply say these standard procedures to try safe mode, clear cache etc. and finally ask us to replace the battery.
But I definitely feel that there is some build issue in Android 9 regarding this which Asus developers has to fix. Because this issue started happening only after the Android 9 update.
This is really killing an otherwise good experience with Asus and making us to consider other manufacturers when buying next phones
