Battery Charged too fast? or Degraded?

Please tell us some basic information before asking for help:
Model Name: ROG Phone 2 12GB RAM 512GB Global
Firmware Version: latest .17.0240.2009.490
Rooted or not: No
Frequency of Occurrence: -
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.
========================================
My 10 months old ROG Phone 2
(Updated: Charged from 0% to 100% only takes 50minutes, so that means my battery reduce half just in 10 months??)
charge from 9% to 71% in 21min, is that even normal? (30W charger)
And I feel the battery life is like 4000mah
normally if im playing a heavy game without X mode, it's around 20% per hour

I always use Battery Care since the first day i got it, usually keep battery not lower than 20-30% before charge it,
sometime below 20% but no less than 8% (very rare i go that low)
and usually charged at 80%, or go to 100% on battery care timer before I leave to work.
Also I usually keep it away from warm place, battery temperature during charging is 39-41 no more than 41c
and 37c during gaming, I know heat is the main reason battery dies fast, so I always keep it as good as possible
but then it can fully charged within an hour, I heard that a normal rog phone 2 with 30w fully charged time is 1hour 40mins+
thats HUGE difference compare to mine...

Standby drain:
4G Data enabled
Wifi Enabled
Bluetooth off
Location off
3%/h if no mistake,
I will GSam Battery monitor from now on and watch closely

Also one thing I would like to say:
Normally it's bad to always charge battery at 100%, but when battery hits 100%, If i let it plugged, for maybe a 10 more minutes. unplug it and use it maybe facebook or some tasks, battery indicator remain 100% lasts for quite a long time (10-20minutes at 100%) before it starts to go down.
is this also normal?

Do you lose 10% per hour when not playing Among Us? Or is it that 3% you mentioned which is the standby drain?

What refresh rate do you use?

I would give safe mode a try to see if you lose the same amount of percentage.

Nope
Standby loses 2.7%/h my latest monitor result
10%/h is playing Among US (120hz i forgot to change it)
Perfect World Mobile game is 21%/h (60hz )
Normally on home screen i use 120hz,
If game support higher than 60fps i will use 120hz
Among US was 30fps, i forgot to turn it back down 60hz , which is 10%/h
I will try safemode and report back

I tried to use phone until it shuts then do a one full cycle charge from 0 to 100 to count charging time
but the very last 1% lasts ridiculously long, it's been 24mins and it's still going,
120hz, full brightness, playing a youtube video, wifi/ 4G data is enabled
is that normal ?
or should I stop now? (since fully deplete battery is bad for battery)
or is it fine i just do it once for a full cycle charge ?
Edit: 36mins now still going

What's your screen on time?
For these kind of things, it is hard to measure as it varies from users to users.

it's always ON since 11%, never screen off until 1% and it's still ongoing,
since it hits 1% and going for another 45mins, still on going
after that I will capture detail statistic form GSAM monitor for battery life
