    Phoronix: What To Do If Still Seeing Poor Linux Battery Life

    Even after using the Linux 2.6.38 kernel power regression workaround for those systems affected by the ASPM (Active-State Power Management) bug that was detected by Phoronix, some Linux users still don't have their netbook/notebook battery lasting as long as they'd wish. For some, Microsoft Windows 7 is still performing better on the battery and/or Ubuntu 10.04 LTS and earlier. As I've said, there's still at least a couple more Linux power regressions and other areas for optimization that I've discovered and still haven't yet publicly documented in full, some in part due to still analyzing what's happening...

    Please upgrade your kernel to 3.2.5 before complaining about battery life. If your battery life is still poor with 3.2.5+ then feel free to report it here.

    This is for a DELL Latitude E5510:

    In Idle state, I have measured
    - 28.1 Watt in Ubuntu 11.04 and
    - 15.0 Watt in Windows 7

    Under Load, I get
    - 50 Watt in Ubuntu 11.04 and
    - 38 Watt in Windows 7

    Measurement was done with a precise device when battery was fully loaded.

    Are the following benchmarks sound reasonable concerning power consumption?

    Do these results sound reasonable? I mean is this consumption acceptable?
