Duplicate of upstream bug as was recommended on IRC Steps to reproduce: 1) Get yourself an Asus laptop 2) Install linux there 3) Set up batter widget with upowerd as backend 4) Have > 3 days (aprox) uptime Expected results: upowerd shows valid battery info real results: upowerd shows 31% and that never changes. In the meantime, acpi -V shows valid battery info (98%, charged).
Try with >=sys-power/upower-0.99.0-r1
