Hello Lowyat people!

I have an iPhone 2G with me, and my iPhone cant seem to charge more than 30% using a USB Charger. I dont have the wall charger because I lost it. The iPhone was working normally a day before, when I cant find a spot to charge my phone so I left it until the phone battery dries flat. The next morning I tried hooking up to a computer, and it wont charge. I was stuck on the red battery screen for a full day and its still cant charge enough to boot the phone. All of a sudden it charge and boot up the phone somehow, now when plugged into the charger it will sometime go from 23% back to 18% then went up again to 22% and so forth but definitely wont reach more than 30%. The battery drain in some cases can drain 1% in 5 seconds!
I've already updated my phone from previous 3.1.2 to newer 3.1.3, did a restore and everything. It doesnt work.
I need to know if anybody faces the same problem, it is the battery's problem ( I need to replace ) or most of the time is the charger itself? I'd really appreciate if someone can help me out

Never mind, it fixed itself just now.
