1) In my  Iqoo neo 9 pro it has a lot of battery draining issue when I don't play games it works fine but when i start playing BGMI then battery draining start.

2) Not much but 2-3 time while playing videos it shows display like glitches and characters into black.
 
3) 4D vibration is not working properly and FPS fluctuations also seen in BGMI.

IQOO team kindly resolve these problems or provide a better solutions.
