Even in airplane mode?

I dare you to do the following:

Charge phone to full 100%. Turn it off.

Put it into a faraday cage, e.g. a steel box, for 7 days.

Take it out again and wonder why the battery is empty.

(The faraday cage has the effect of making the modem have to switch bands constantly, which costs more electricity than sleep mode in LTE)
