Comment 457 for bug 1776563

Windows 10 when installed and at first day(s) make a lot of tests for system health and configuration, especially when idle, even .NET compilations. Another factor is the edition you use with/without store and universal apps that run in the background. Most of all you need to use the power profile that Acer provides. Do you have the model with SSD, do you have the extra GPU model, do you use high/low brightness... For me Windows 10 give almost 5 hours max but average use 4 1/2 maybe. I compared with Ubuntu default settings and low brightness with same hardware and got almost 3 hours battery time.

Richard I haven't tried yet the powersave settings, I will wait for the final release of 19.04 to re-install it on my hard disk.
