Dead Cell Phone Battery?
 

Just bought a new cell phone battery because my last one died out. After a couple of days my phone isn't starting up again. It wont charge when i use my phone charger and a usb cable. anyway of checking if the battery is dead

maybe your phone isn't charging the battery. it would take years for a battery to die out and its normally a gradual process. so unless you have a really old phone your original battery is probably fine too

try getting a friend with the same phone to charge your battery for you
