I have problem with 100% CPU usage at idle since i buy it on Xiaomi Redmi Note 8 Pro. Battery draining so fast especially in games. CPU Usage never goes below 25% at idle. Bad unit or?

Should i downgrade OS to MIUI 10?
 
Sounds like that could be the case. What are you using to measure the CPU acitivity?
 
I'd guess either corrupt firmware or a faulty CPU. The first thing to try would be a factory reset.
 
Next step would be to reinstall the firmware, if possible. Try this: https://c.mi.com/thread-2637280-1-0.html. (Sorry, but I wouldn't be able to help in more detail, since I have no experience with this process.)

Otherwise, look into getting a replacement if the phone is still under warranty, or bring it to a repair shop.
 
I had the same problem with Xiaomi Redmi 8A and it had even higher CPU usage at idle with no apps opened then Redmi Note 8 Pro. I bought it in the same store.
 
I think it's not OS because i lose 1% battery just in Fastboot Mode after 1 minute. What about bad battery?

Check in CPU-Z app what the battery volts and temp at, can give some indication , and yes lower voltage or failing battery can cause issues on CPU . But these things only a real good repair shop can test .
 
Here is CPU-Z screenshot.

So, it's CPU or bad battery? Battery Drain start when i first time turn on phone. The same with Redmi 8A.
