I've found three bugs on the December update.

1. Notification bar icon stuck when resolution set to 2400x1080(image attached)

2. Power consumption by apps was not displaying(video attached)

3. Battery drain issue. Getting SOT of 5.30 hours only even when resolution is 2400x1080 and battery saver was On all day( image attached). Also I've not used any heavy application.

Kindly fix the issues ASAP in the next update. I'm posting the issue for the third time as the post is keep on getting deleted.
