Why is my iPhone dying so quickly and won't turn on?

My iPhone 4s was purchased last Christmas so it is fairly new. But for the last two months or so I have been experiencing rapid battery loss. I have to travel with a portable charger because even with out use it will drop from 100% to 30% in about 40 minutes. I have literally watched it go from 75% to 13%, skipping all the numbers in between and giving me a notification that I have less than 20%.It baffles me how quickly it loses percentage and how it skips numbers. It also will die at any amount (I have seen it die at 94%) and refuse to turn on without a charger. All of my settings that drain the battery have been turned off and I have double clicked and deleted running apps. After talking with a knowledgeable technician we decided to do a factory reset but before I got the chance my phone died and has been plugged in for over 6 hours now and refuses to turn on. All it shows is the red battery symbol and a lightning bolt which phones usually do before they turn on. But most phones do not six hours. Please help if you are an expert or have any ideas. I have tried all the obvious stuff and even though very unlikely could it be a virus? Is it a battery shortage? The problem just seems to be worsening.

Is it okay that I have an iPhone 5?

Using iPhone as flash drive?

I don't have enough memory on my Xbox to download a game, and I was planning on getting a flash drive today. However it started storming and I don't feel like dealing with driving in the rain and I know there are several apps that you can basically use your iPhone as a flash drive. Would that work for my Xbox?

I forgot my passcode on my iphone

I have tried everything i've come across online… I've gotten as far as half way of a restore (using the dfu mode and what not) gets half way restoring, then a message pops up saying "Can't restore, iphone is passcode protected, please enter code and continue.) the whole reason i'm doing this is to bypass my forgotten passcode. Any help is greatly appreciated. P. S. I have done the holding home button, and then power button, or holding home button then plug in the i tunes connector, and restoring, everything… But I eventually get this message saying I need to enter the passcode?

Every time I try to send a picture it won't go through. I have a feeling it's because I have the cellular option off so I can only have Internet when there's Wi-Fi.
