Jailbroken battery won't charge?

This has happened once before, but this time I can't figure out how to fix it. My iPhone 4S is jailbroken and had a weird battery glitch. I had it plugged up and confirmed it was charging all night, but when I woke up it was at 50%. I was gone for 10-15 minutes, and when I came back it was at 34%. I plugged it up and the icon said it was charging but the battery percentage kept dropping lower and lower every minute. My phone was dead within an hour. I've had it charging all afternoon now but it still says there's no charge and won't turn on. I tried removing the jailbreak before it died but it didn't finish in time. Has anyone else had this problem? Any solutions or suggestions?

Why does my Iphone shut down at 20%?

When I first got my Iphone 5, it would usually keep running until it got to about 8% battery. However, these past couple of weeks I'm starting to notice that it shuts down at around 20%.Is there a way to fix this problem?

Which iphone would you choose?

Considering that these 2 iPhones cost the same
would you choose a factory unlocked iphone 4 Or an iphone 4s with Gevey sim?

My JailBroken Iphone can't connect to my Wi-Fi?

If you want to just get straight to my problem skip to the all caps part.

I Jailbroke my iphone 4 back about 2 years ago (so long ago i'm still running on ios 5.0.1) I'll start with a little bit of back story. About 2 months ago, i noticed while trying to install an app that my storage was full. I thought this was weird considering i didn't have very many apps to begin with, and only had 2 gigs of media on it (i have an 8 GB memory) so i checked and came across a common problem with jailbroken phone, the "other" storage. So i hooked up my phone to itunes and noticed a whopping 5.4 GB of other storage on my phone. And so my quest began. I spent hours trying to get rid of it. The solution for getting rid of other storage is to factory reset my iphone. Simple. But with my luck, it wasn't. I backed up my phone and began to restore my phone, a process which is normally very easy for people, but of course, more problems. Every time i try to reset my phone on itunes, i get the problem where it endlessly tells me to connect my phone to itunes by putting it into recovery mode, and then my computer can't pick up or find my iphone. I used tinyumbrella to get it out. Whenever i try to restore my phone manually (on the phone itself) i get the spinning wheel of death. At this point, i'm like *** it. Today i tried again and after hours of trial and error i somehow deleted all media and apps possible (as well as deleting random files in the cydia app ifile) and tried again. Finally it worked. Sort of. All my music and apps are gone but now i have a full 4 GB free which would be fine. HERES THE PROBLEM. I some how got rid of the "other" storage and decided to update my phone, it then prompted me to connect to a Wi-Fi network first, when i noticed that i wasn't connect to my home Wi-Fi. When i went to my Wi-Fi settings my home network showed up and i correctly entered my wep key. Now next to my network it shows the spinning symbol that it would show if it were connecting to the network, but it won't. IT just keeps on trying to connect, but it won't. I checked every other device in my house. They all work fine. So being myself i started messing with my phone settings, trying to see if there was anything turned off or something. Then something strange happened. I decided to try and put my airplane mode on for shits and giggles, but i noticed that the airplane won't show up in the upper left hand corner. I exited my settings and went back in and noticed that airplane mode was off and just doesn't work as a whole.So. Story of my life with my neat little apple product. Currently my phone is sitting next still trying to connect to my network. Right now its pretty much just a brick charging me money for going over my 3g limit for the month. So if anyone has ANY idea on how i could fix this, please tell me and ill love you. Forever.

Some extra details: I haven't tried any other networks yet, but i don't think that would help anything.
I STILL can't restore my phone, if anyone knows how to completly fix that recovery mode bug or the spinning wheel of death, thatd be great too.
While i was reseting my phone i accidently Reset my Network Settings. So yeah. That might be why this happened. But still. I need a way to fix this.
