- robocat 8y agoI wonder whether that is causation or correlation? AFAIK the WiFi hardware doesn't use much power itself, although I might guess that background protocol chitchat could cause CPU usage. I think that when I am usually using WiFi I am also usually using a browser that chews power.
- chadlavi 8y agoTurning off wifi is probably just turning off your ability to do a lot of heavy processing as you interact with the internet, right?
- jandrese 8y agoThis is my thought. Turn off wifi and you're no longer running the cpu and memory monster that is a web browser. But this is something Apple does right. My wife noticed that she can get around 50% more battery life out of her Macbook using Safari instead of Firefox. (7-8 hours instead of 4-5).
