I think you may have sevral thinger 2 be checked:
1.How many batteries do U have?You must got 2.So just use the left one to check wh
ether ur charger worked normally?The batteries cant be charged if it's raddled.So it's natural ur phone turned off.All u need 2 do is changing a new one.
2.make sure the battery you;ve charged is intact!IMO,it's most probably raddled.
Soory for my poor English,Hope you can get my idea.:D
