BB Curve :: It Won't Charge/battery Drains Quickly

My bb has been annoying me for sometime because it drains the battery so quickly. I've deleted lots of apps etc I don't use to try and help, and I make sure I properly close everything down so it's not running in the background etc. Even if I put it on standby mode the battery has usually drained by about 1pm even though it's been fully charged.Me and my fiance have the same phone so I've tried his battery/charger etc. If I use his fully charged battery the same thing was happening. On saturday though, it just will not charge at all. A red light comes on and goes and that's it. If I use a fully charged battery it will still last a few hours, but I can't charge it myself.It's a bit of a nightmare as my fiance had emergency surgery last night so we need to both have working phones so he can contact me from the hospital if he needs to, and I need to take his phone home to charge at night, but it's leaving me without a working phone.
