========================================
ROG phone 2 is having battery drain issue since Android 10. Asus should've released an update to fix this, but instead they left ROG 2 and ROG 3 devices. I downgraded to A9 because of this issue but again upgraded to A11, to check is this issue is still there. Android system is consuming 20-30%+ battery. Asus should atleast release a fix for this.
