    OS battery life hours estimate question

    When off commercial power and on battery, is the 'time remaining' based upon the OS' experience with the installed battery/condition or simply based upon the time a certain spec battery 'should' last without regarding the actual health of the battery?

    While not absolutely positive, I'm sure its the former. I can watch mine "speed up" (less time remaining) when on battery when playing a video or even a flash game as opposed to just surfing/reading. I have a small battery, compared to my machines requirements/power, so kinda pay attention to the battery when using it and yes it will change depending on the load. Which suggests to me that its "reading" the consumption/state of the battery instead of basing it on something else.

    If you Generate Battery Usage Report in Windows 10 the battery life estimates there are based on actual observed drain. I see no reason why the taskbar icon wouldn't be based on observed drain too.

    Thanks so much (and of course Brink). I just ran the report. What a fantastic utility!
