"At this point I’m not sure there’s a need for normal users to actually turn off Wi-Fi"

To preserve battery. I don't know about iPhones, but on my Android phone, Wi-Fi is certainly the largest battery hog, if I leave Wi-Fi location scanning on.




I would LOVE to see someone run benchmarks about how much battery WiFi and BT use on modern iPhones (when disconnected). I would be amazed if the difference was more than negligable.


It is absolutely not negligible on my Moto X Play.

I get around 1.5 days normally, less than a day if I use wifi and BT.


That's strange. I have used Nexus phones since the first one that came out and I have never experienced any significant battery drain from either wifi or bluetooth. First was always screen, second Android system.

Just checked again to make sure. Wifi 0%, Bluetooth 0%


Mine is usually wifi, then screen.

Right now wifi is at 8%, and I used it for maybe 15 minutes this morning, that's it.

Motorola Moto X Play, Android 6.0.1, for what it's worth.

As far as I know, Marshmallow has a battery drain issue, but Motorola (now Lenovo) does not seem to be interested in updating their software anymore.


I just wanted to mention that I've done a full factory reset of my phone now, and it seems that wifi is using a lot less battery, even with wifi scanning etc. switched on.
