could this hurt my phone? (physically)

Have you used it and it works?

I don't see how it would hurt anything, as long as none of the wires are touching.

 

As long as you turn the ringtone, notifications, and media volume down it shouldn't make a peep. But to answer your question, I don't see how it could hurt your phone at all.

 

Assuming that you took care to make sure that the wires are not touching, you have an open headphone circuit. I really don't know if this could cause any problem with the small headphone amp, but why don't you just turn the phone off during class. It doesn't take that long to turn it on again after class.

 

To be sure, try this:

From an electrical standpoint, use a multimeter to test for continuity (i.e. a short) between any two of the contacts on the extended part of the plug. If there is no short, the circuitry of your phone should be safe.

From a physical standpoint, I doubt that leaving the plug inserted could cause the jack to become lose, but can't say for sure.

 

By how you described it, it sounds like you are running a risk of starting a fire or something lol. I was worried about my phone going off at work and then I found out about Locale. Locale is a very handy app. You can set the app to silence your phone when you enter a specific gps area/location. So, if you forget to silence your phone when you get to work/school, the Locale app has your back. And of course you can use it for many other things as well.

 

I think that's actually a clever little fail safe! If there are no speakers drawing power, I don't see how it can hurt.

 

Press and Hold the power button, then when the menu comes up, select Silent Mode.

It will turn all the volumns off.

 

Whew!

And I was afraid you had Duct Tapes your little buddy to keep it's mouth shut ...:icon_ devil:

Seriously, it won't hurt it, but just set to silent, same thing.

 

Put a little electrical tape over the ends of the wires, but yeah it should be fine.
