IPhone 5s Rapidly losing battery?

I bought my unlocked iPhone 5s 32GB sometime between October and November (sorry i can't remember the exact time) and recently (within the last month) my iPhone has been noticeably losing battery at a ridiculously fast rate. Today when i went to school i had full battery charge and when i came home i had only 7% left, and i only used my iPhone for about an hour listing to music with the screen off and not web surfing. I also made sure to turn off anything that sends or receives signals (except for data although i didn't use it) and turn down the brightness of the screen about to half way. I'm just wondering if there's anything else i can do to ether fix this problem or minimize it. The phone also seems not to charge as fast anymore and i'm wondering if there could be battery damage. Although i haven't dropped the phone or damaged it in any way. I have already looked up this question on the internet and i have tried everything they have recommended but it hasn't helped so far. Any ideas would be much appreciated!

How to retrieve deleted information on a game on a iphone?

Ok here's the story so I was trying to delete InfinityBlade3 because the game crashes a lot on my iphone and I need the space to install the update for GTA San Andreas on my iPhone, but I accidentally deleted KOTOR or Star wars Knights of the Old Republic for short on my iPhone 4S. Then that leads to my question is their any way to retrieve that deleted information on KOTOR?!

Lifeproof case for iphone Real Or Fake?

So on eBay I've bought a lifeproof case for my iphone and I'm wondering if I bought a fake. I've watched a bunch of videos on spotting a fake but does it apply to Canada? Where I'm previously at right now, and in a lot of the videos they say there shouldn't be foreign language on the packages, but being that I'm in Canada where there's also French Canadians who speak obviously French. Could the case i bought be legit?

Button on the top of my iPhone 5s is loose?

I got an iPhone 5s in early December, but the button on the top is wobbly. It still works, but it is not level (slightly slanted) and also it wobbles abit (like if I tap the back of my iPhone at the top it makes a shaking noise).

Like I say, the button still works, and my iPhone still works 100% fine, but it is just annoying me. I suppose it is like buying a car with a scratch on it. The scratch doesn't effect the performance, but it is still annoying.

Are these buttons knowing for breaking easily? And if it was annoying you would you want it fixed? And even if I took it to a repair shop would they even bother fixing it, as the button isn't actually broken.

I know most of you will think 'just be thankful you have an iPhone 5s at all', and believe, I'm. But I just can't help it annoying me.
