Again, this is configurable and depends on circumstances. There is a
graphic that depict how much power was used by each major application,
and WiFi is typically large. It can show a solid bar or broken, showing
when it was on.

On my tablet, WiFi shows 8% of battery power used, and operating system
24%. Display is 2%. It predicts that it will last 4 days more, and last
charge was two days ago.


On my tablet, power settings, I can tell the WiFi to never power up
automatically when the device is on standby. Another setting is to leave
on automatic, to power up as needed. I have more settings than you.

No SIM.
