Bug Description
It was reported that the Pro 5 is draining battery and I can confirm we're seeing unusually high CPU usage when the device is idle (with screen on).
Steps:
* turn the screen on
* monitor top output
Expected:
* unity8 under/around 1% CPU usage
Current:
* unity8 around 10% CPU usage
I've confirmed it's not rendering, will be looking at a perf report when I get it.

I know you say it is not rendering, but just in case this happens in previews can you try if https:/
