Why does my iPhone shut off when it is unplugged?

Well for a while now my iPhone has been shutting off when I unplug it. Sometimes the battery would just stay at a same percent for a while and I will take it off the charger and plug it back in, then my phone would shut off and come back on. That would keep the battery going up. Also lately, my phone has been receiving text messages really late and unless I turn my phone off I would get the messages late. Anyone has any suggestions?

Other section on iPhone 4s filled?

I have a month old iphone 4s 16gb. I have 392 songs. I have 441 pictures. I got a message saying my storage is almost full and when I plugged in my phone it says all my storage is taken up by "other"… About 9.52 gb. I googled what to do and it told me to restore my phone and when I restored it the other section just grew bigger, even after it deleted all of my apps, What do i do?

Is it dangerous in the Bronx for tourists?

I'm going to New York and going to the bronx. Is it dangerous for tourists? I'm planning to go to the Bronx zoo. I heard people say don't flash out your iphone or you get jumped, but what happens if i want to take a picture or call someone? Can i get robbed easily? Also how can i act city-smart? How much money should i bring when i'm there? How do i walk safely at night time or ride on the subway at night?

How to get my iPhone out of Recovery Mode Loop?

Basically, my iPhone 3GS is stuck in a recovery mode loop.
I've installed applications programmed to get it out of such a situation, however, whenever i click the "exit recovery mode loop" button or something like that, the iPhone shuts down, disabling the application to get it out of the loop.
I've tried
TinyUmbrella
- iPhone shut down when I tried to exit the loop
2. IREB
-Had no effect
3. IHackintosh
-Couldn't even download the software
4. FixRecovery(which is supposedly TinyUmbrella but i think it's different)
-All was going well until something in the HTML code or something went wrong (something about waiting 60, 000 ms for something to happen and giving up)
I've also attempted changing the hosts, but that had no effect. As of now, I've created a custom IPSW and restored the iPhone to it but the unknown error (3914) keeps occuring. The error 29 has also happened but I believe that's what I'm trying to fix.

CAN ANYBODY AT LEAST TELL ME WHAT IS GOING WRONG OR THAT THERE's NO POSSIBLE Way TO FIX THIS ABOMINATION OF AN IPHONE AND CAN STOP TRYING NOW! MY BACK HURTS So BAD!

BTW, I don't really have anything on the iPhone and wouldn't mind losing the contents.

OH and the iPhone was a handydown from my Pa, who jailbroke it( or tried to, I don't know) and that might be the reason I'm here in the first place.

Help WOULD BE MUCH APPRECIATED
RLLY
Please
Help ME

I also don't remember the iOS but the one in my custom IPSW that I'm trying to restore to is 5.0
