IPhone 5 battery messing up?

Ok so my iPhone 5 is only about 5 months old and for the past 2 or three months the battery is being weird. The battery level goes down really fast sometime and now the new thing is to turn off at random times. Yesterday it was on 50% battery and turned off wouldn't turn back on it was giving the connect to charger sign i plugged it in and it immediately turned on and said 43% so obviously it wasn't dead It still continues to do that at random percents. I restarted it holding down the home and lock button and removed the sim to check for water damage. So what's wrong with it. And another thing if i need a new one covered by insurance are they gonna give me another 5 because my friend had to get the 5c when hers got lost

I don't have a vibrator so. I want one that's free, that actually makes my phone vibrate, most claim to work but don't, also it's for my Iphone, so on the apple store, please help! I need this like now. If you don't know of apps, how can I make my phone vibrate then?

Share ethernet connection to iphone with no Wi-Fi?

I'm in my dorm room at school and I don't have a Wi-Fi connection to my laptop, I have it plugged in to an ethernet cable and have tried sharing that connection to my iphone but it usually only works if my laptop also has a Wi-Fi signal. I was wondering if there was anyway to get Wi-Fi on my phone when I don't have Wi-Fi on my laptop, either through ethernet or bluetooth or whatever.

Do i need a case for my gold iPhone 5s?

I have the gold iPhone 5s. I have many cases, including the Apple leather one, but am not really satisfied with any of them. I really want to FEEL the phone, like the thinness and lightness. Do I need a case for it? I do understand it scratches, because someone I know has the gold one and theirs has 3 large scratches on the back, so the silver shines through. So my question is, do I need a case or will a front and back (and maybe sides) screen protector be good enough? I also have Applecare plus.

By the way i asked this question twice because nobody answered the first time LOL

I wish I was born in a different generation?

I think this generation sucks. Technology is taking over. People are becoming anti social and rather stay home and play video games, watch tv or spend the night on the Internet. It's getting bad. I wish I wasn't a teen in this generation. What ever happened to hanging out with your friends all day and just living life, and now a days you can't really get a job until your 16, and its not like a good/ cool job like back then in the 80's/70's its McDonald's. You have to go to driver ed or you can't get your license until 18. Only some music is good but seriously justin bieber and one direction need to not exist there such sissy artists and life is so boring and complicated. I wish It were the simpler times where you could stay out late until you mom called you in for dinner. I wish I can carry on a conversation without some getting distracted with there iPhones. Even 8 year olds have smartphones and they know about sex. The word love is so misused and nothing means anything anymore.
