So the quoted 2 year battery life is supposedly achievable using a bluetooth connection. The K380 only has bluetooth, no unifying receiver. The mouse has so far remained at 100% charge for the past 4 weeks and works flawlessly.Ġ bluetooth tpacpi_bluetooth_sw Bluetooth unblocked unblockedĢ wlan phy0 Wireless LAN unblocked unblockedġ0 bluetooth hci0 Bluetooth unblocked unblocked` I have a Logitech bluetooth mouse too, so that’s why there are two devices shown. (Note that the ‘hci0’ is my bluetooth device and may not be the same as yours) Possibly journalctl | grep -iE "hci0|bluetooth" may give you some info, especially in cases where there are frequent connects and disconnects.

It may be a failing of fedora as you suspect, or it may be due to other conditions that interfere with the signal. Weak signals with intermittent drops and reconnects are one of the causes of this condition. Bluetooth devices work similarly in that when the paired partner is in contact they are happy, and if they don’t have contact with the partner then they constantly search. Have you noted that your phone battery drains faster when you are in an area where service is limited or non-existent? If there is no good service connection the phone has to constantly ping for a tower to get service which drains the battery faster. Like wifi, bluetooth has a limited number of rf bands it uses, and the more devices in use the busier the rf in those bands so the more each device has to search for its paired device. I suspect the rapid drain is due to bluetooth, and not necessarily directly because of fedora. I am using the logitech K350 keyboard with the logitech unifying receiver and I usually get 2 to 3 months on the batteries. ![]()
