I have a Touch, and all my classmates borrowed it. It ran out of power after two classes. For some reason, I have to carry it with me every day, and my classmates are too embarrassed to refuse. What should I do?

Haha, this is too normal.

Next time, leave 70% of your charge for me to play with. I haven't played it yet.

Then borrow them, haha, they won’t dare to play for too long.

I will use this trick. I borrowed it from someone and told him to leave some battery for me and let me play for a while. Haha
