IPhone isn't letting me go on Usage?

I really want my battery percentage to show at the top of my iPhone, and you change that by going into Settings > General > Usage > Battery Percentage but every time I press Usage it just pauses for a moment then kicks me back to the home screen. I haven't messed around with any settings so I honestly don't know what's going on.

Why can't I listen to my music on my Iphone 5?

Whenever I open my music app, it will sit at the main page, and when I touch a song to play it (whether on the all songs list, or in a playlist), it doesn't play the song, and the app freezes. When I plug it in to my computer to try to reset my iphone, and I click on the iphone icon, my itunes freezes. When I go into my iphone settings, and touch the music settings, my settings app freezes.

Is the voice memo's app on the iphone a reliable utility to record yourself singing?

Singing is one of my passions and I record myself singing a lot. And i sound Ok i guess, but i just want to know is this exactly how i sound? Cause i have heard before that iphone recordings aren't 100% accurate in terms of determining how your singing voice sounds. And in my opinion, the sound is very distorted and not the best quality i guess (I have the iphone 4 btw if that makes any difference). So i just wanna know, is it reliable? And if not, what app can i download, (preferably free) or some recording thing i can buy lol i don't know something that will make me see what my voice exactly sounds like or something really close to exact.

Droid Mini for a college student?

Hi, I'm a college student who is typically on campus for 5 hours, then I go to work until around 4. I currently have a Samsung Fascinate (it's old, I know…) and it can't hold a charge from 6:00 AM to 4 PM. So I've been looking into upgrading and I've narrowed it down to iPhone 5, Droid Ultra and Droid Mini. I'm a fan of smaller phones, and I really need one that's going to last me at LEAST 16 hours. Keep in mind it will be on school Wi-Fi, I'll use it lightly (check email occasionally) and it will be charged every night. Will the Droid Mini last me around 16 hours? I'm really curious. The internet is very opinionated, and "battery drain tests" are in my opinion, a flawed way to test a battery. Please give me advice! Thanks! (Sorry it's so long, really need a quality phone.)

No iPhones, I can't afford Applecare at this time.

How to get revenge on someone that stole your idea for something?

Last week, I bought the full version of GarageBand, and created a melody for a song that our music teacher and our class are making. After I played it to him, he said it is OK, and he used a melody similar to mine. Then when we were going back to class, I told a kid in our class that I used GarageBand, and I told him how awesome it is. Then when the kid got home, he seceretly bought GarageBand, and made a melody that's better than mine. Next music class, he brought his iphone with the melody on it and played it to the teacher. The teacher appreciated his melody more than mine, and way more many kids liked his melody more than mine, and our music teacher used his exact melody for the song. How do I get revenge on him for stealing my idea of making a melody for our song?
