The capacity level mappings are taken from: https://support.steelseries.com/hc/en-us/articles/360049205612-How-do-I-know-the-Arctis-battery-level-how-do-I-charge-the-Arctis Even if we have a percentage, exporting a capacity_level that matches with the hardware warning levels means that upower can show warnings at the same time as the hardware. So the headset starts beeping at the same time as the critical warning notification appears :eyeroll: Signed-off-by: Bastien Nocera <hadess@hadess.net> --- drivers/hid/hid-steelseries.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
