Please tell us some basic information before asking for help:
Model Name: rog phone 5
Firmware Version:
Rooted or not:
Frequency of Occurrence: everytime after the only first time I saw it works at battery 9%
APP Name & APP Version (If your issue relates to the 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.
========================================
Is it normal for my rog 5 shutdown at battery level about just below 20%?
I saw my phone once works under 10% n it shows a red light notification when it reach 9%, after that I charge my phone everytime before it shutdown.
But recently my rog 5 shutdown at the middle I watch YouTube at battery level somewhere below 20% (everytime in last few days). I thought the battery might drained up coz by watching YouTube; but just now at the middle of replying zentalk my rog 5 shutdown again at battery level somewhere below 20% as well. Is this normal? It seems like I can only occupy the battery between 80-20% only? Thanks
My setting is dynamic n auto for refresh rate.
Ps: pls do not ask me to generate the log as I'm not well versed in tech stuff n I hv no time for it.

Since it seems to go out before 0%, I'll add to wait a few minutes after it goes out and try to turn it back on. if it does not want to turn on, plug in and charge but if it turns on again, wait for it to turn off again, start over if necessary.
In the latter case, if it is turned back on with 10% or more battery power when it was off long before it was 0%, this is not a good sign for the battery.

After I got it charged to full (99%) n now it shutdown again at +/-20%. 
Fyi, I can't get it charge until 100%, it will stay at 99% (I waited 10min), is this normal? From 0-99% it takes around 30min+ but it will stay at 99% only. I scared it would damage the phone so I decided to stop charging it after waited 10min at 99%; or should I waited until 100%?
Now again I'll see if it shutdown again at +/-20%, n will ask for help if this happen again. Thanks

Try turning off battery care completely and let it shut down by itself.
Keep turning it on and leave the phone on so it completely drained of battery juice.
Once it is completely off and doesn't turn on, leave it charging to 100%.

Thanks for your advice. Fyi, once it shutdown at +/-20% it won't turn on again.
Yesterday I charge it to only 99% (and keep changing for 10min still remain 99%), n after that it can last for 4hours before it drop to 98%. Is this normal? Normally my consumption of battery is +/-5% an hour, too good to be true it can last for so many hours at 99%?
I'll try charging it to 100% next round. Thanks.
