I have been spending a lot of time working remotely with my laptop in random locations. And usually just plug my mouse in via the USB dongle. But just curious if there is a noticeable battery difference doing this? Seems like Bluetooth would be better because itβs already powering other things anyway.
Edit: seems like itβs Bluetooth. Going to have to change my habits. Thanks all.
Less power on the side of the host computer or the mouse?
Not sure but im pretry sure both a so negligible its completely irrelevant
Years ago it was relevant (like 15 years ago). I had a BT mouse then, and it was a power hog. So much so it was rechargeable with its own charging dock. And yes, when you walked away for the day you better dock it!
But Iβm sure itβs far, far better now. Logitech advertises some of theirβs as having 1 year battery like, on a single AA battery
Bluetooth uses less power, because usually the polling rate is lower. This is from my mouseβs manual:
Bluetooth mode has lower report rate compared to LIGHTSPEED. In Bluetooth mode, G604 has longer battery life as well.
The batteries in my Logitech wireless trackball and keyboard last several months to more than a year. The keyboard in particular lasts really long. I have these on my work computer, so they are getting heavy use.
Bluetooth (BLE) is impressive, I have seen a BLE device being stuck to a window in an office, and with just the vibration of the glass, it created enough energy to send small data packets to a PC 10ft away.
