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 it’s already powering other things anyway.

Edit: seems like it’s Bluetooth. Going to have to change my habits. Thanks all.

    I’ve always assumed the dongle uses bluetooth as well. Why invent a new protocol when there’s one that does exactly what you want?

      Dongles are usually 2.4ghz radios, supposed to be lower latency and more stable than Bluetooth.

      Edit- in reality though, bluetooth has come a long way and generally more convenient, users likely wouldn’t notice a difference in day to day work. Personally I still wouldn’t recommend gaming on a bluetooth connection when latency and micro stutters matter.

        That’s the same frequency as one of the main Wi-Fi bands, I would imagine they’re probably just reusing that technology for this communication

          KB/mouse dongles use their own, often proprietary, protocols but on the same 2.4 GHz band. It’s like how WiFi and Bluetooth both operate on 2.4 GHz but use different framing and protocols.

            Interesting, I did not know how widely used the 2.4GHz band is, thanks for correcting me!

          It’s also the frequency of Bluetooth and your microwave because it’s unregulated. Dongles aren’t Wi-Fi or anything like it.
