Created attachment 153595 [details] Notification_low_batery_levelo-for-blutethooth_device SUMMARY Couple days ago after I connected my bluetooth device (headset ATH-ANC900BT) I got notification about low level of battery (10%). I checked in Bluetooth plasmoid and found value 60%. After that every time I saw this notification I ignored it and relied only on information presented in Bluetooth plasmoid. Seems notification gets information about low level of battery from different place or in different way than Bluetooth plasmoid. Please notice in my configuration there is turned on option "Enables experimental features and interfaces" - file /etc/bluetooth/main.conf to get battery level. STEPS TO REPRODUCE 1. Connect bluetooth headset which exhibits battery level 2. Pay attention on notification shown after connection will finishes with success 3. Check also Bluetooth plasmoid clicking in proper icon in TaskBar OBSERVED RESULT Discrepancy in notification and Bluetooth plasmoid for battery level EXPECTED RESULT Don't show notification in battery level until battery level will be 10% or less SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.15 (I guessed values due to KInfoCenter and System settings crash) ADDITIONAL INFORMATION $ cat /etc/lsb-release DISTRIB_ID=neon DISTRIB_RELEASE=22.04 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="KDE neon Unstable Edition"

Please post the output of "upower -d"
Created attachment 153608 [details] upower -d I run command "upower -d" in moment my headset is connected. In this moment battery level is 100% (shown by bluetooth plasmoid).
The value in the bluetooth applet comes directly from bluez. The value in the battery applet and the low battery notification come from upower (which in turn gets it from bluez). It could well be that those two report different values sometimes

Battery level decreased to 80%. Again I receive notification about low battery (because level 10%) what for sure is not truth.

Still an issue in Plasma 6 built from git master. Powerdevil even shows two entries for my Bluetooth mouse with different values 50% and 55% with slightly different names. Whereas the Bluetooth applet and KCM show 100%.
