I'll use USB if
I'm going to be tethered for a
while, so that I don't run down the phone battery.
USB charges the phone at the expense of the laptop battery 😛
Wifi on the 5Ghz band seems to drain very slowly for me, with the
phone
just a foot away. Still at 100% after 25 minutes. I did not check
yesterday the figures.
The thing is, BT power is negligible, that's why I was tempted.
If I'm tethered long enough to worry about the battery, my computer
is plugged into AC power. Years ago, I used the WiFi tether and
then forgot to turn it off. I was left with a dead battery. These
days, however, the WiFi hotspot will turn off after 10 minutes
without a connection.
BTW, my own computer, an eleven year old ThinkPad E520, only
supports 2.4 GHz WiFi. ðŸ˜
It also doesn't have Bluetooth.
