In the general population, enabling bluetooth is not a battery drain. Quite the contrary; having it turned off tends to result in worse battery life.

If you are reliably experiencing something you can clearly pin on Bluetooth, you either have very unusual usage patterns, or are experiencing a severe bug.

Having bluetooth turned off results in _worse_ battery life? How so?


Disabled Bluetooth in certain decision trees leads to spinning up more expensive radios, when passive Bluetooth would have worked effectively, for less power.


Can you give a concrete example? This seems counter to my personal experience.


I'm genuinely curious how WiFi + Bluetooth enabled could consume less power than WiFi alone?

The only time I use Bluetooth is for AirDrop. And that requires turning personal hotspot off.
