How significant? Turn the screen black, and show the remaining battery time estimate. Turn it white, do the same. I'm curious.
- firethief 7y agoSurely it isn't extrapolating from current instantaneous power consumption?
- camgunz 7y agoI'm pretty sure that's how it works. The drivers report total battery capacity, current battery capacity, and current power draw, so the meters just do the math.
- iforgotpassword 7y agoBattery at 74%. Sitting at black screen for about a minute, the highest estimate I got was 4:50, lowest 4:05. It was mostly showing numbers close to either of these, almost never something in between. Switching to white I got 5:40 and 4:50 showing pretty much the same behavior. It's an HP pavilion 15-p005ng with a Pentium N3530. Terrible machine btw. Linux freezes in irregular intervals, almost immediately with OpenGL stuff...
