I have a normal Google Android phone that i noticed runs out of batteries so quickly even if turned off. So I did a quick experiment.
I removed the battery for a few days. Wouldn't you know it, the charge was exactly as I left it, unlike before. Makes you wonder what exactly that phone is doing using power while supposedly turned off.
Burners don't work if they really wanted to get you. It's just an inconvenience for them so they pick on someone else.
