Well i would try another battery since they arent too expensive . Also try a standalone charger , the ports on our phones are horrible . ive replaced too many to count . Take it to sprint or whoever you have to help diagnose it . it almost sounds to me as if the phone itself is short circuting . Has the moisture sensor been tripped ?

again my personal next step would be the standalone charger option . then pop the battery into the phone with a full charge and see what happens . (BTW buy a new battery for the standalone charger , this will help eliminate the battery being a problem) it wouldnt surprise me if the charging port is shorted somewhere .
