Doing a wipe or accessing the BB from a PC wont work unless the phone is running. Unless you dropped it or got it wet the likely problem is the battery is defective. There is some controversy on the charging of an LI battery used in cell phones but from my experience if the battery drops too low, below 25% the battery will eventually fail to fully charge. If you let it run down often it may be the battery. Try to borrow one from another friend or simply buy one. Do not get a cheap knock off . Get a OEM blackberry battery. Good luck.
