A slightly off-the-wall request, but does anyone know how to tame the mouse/peripheral battery nags under Plasma with Leap 15.2? I've a Logitech M705 mouse which has 2xAA 2450mAh rechargeable batteries. Somewhere in the Leap 15.1 update cycle (I think) I started getting nags about low-battery in the mouse. At first I thought "how helpful" as the same type of geniunely flat batteries in my wireless keyboard sent me on an epic wild-goose chase a few years ago (hint, no probs in the graphic driver). Twice. Here's the notification message: Mouse Battery Low (10% Remaining) The battery in ("Marathon Mouse/Performance Plus M705") is running low, and the device may turn off at any time. Please recharge or replace the battery. I'm guessing the slightly lower voltage in low self-discharge rechargeable batteries is confusing upower, but I can't find where/if it can be tuned. The level is reported regularly by the mouse itself, as it returns from low power/auto sleep mode. Yes, I've tried a fresh set of rechargeables, after their 20hr topup. Regular AA's are rated for three years in the mouse, so would expect at least 12 with high capacity rechargeables. upower --dump reports (for this device): Device: /org/freedesktop/UPower/devices/mouse_hidpp_battery_1 native-path: hidpp_battery_1 model: Marathon Mouse/Performance Plus M705 serial: 406d-13-d9-8d-16 power supply: no updated: Fri 26 Mar 2021 18:07:57 GMT (12 seconds ago) has history: yes has statistics: yes mouse present: yes rechargeable: yes state: discharging warning-level: low battery-level: low percentage: 10% (should be ignored) icon-name: 'battery-caution-symbolic' 10% is clearly wrong and something needs re-calibrating.
