What uses less power for a mouse, USB dongle or Bluetooth? (lemmy.world)

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~~

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