Phone not charging and alert tone doesnt stop.

[WPCentral Question]

My Nokia windows phone only appears to be charging 1/4 - 1/2 way after being on charge all night and the alert tone constantly keeps sounding.

Try different charger

Let the battery die to 0% to recalibrate it and see if that makes a difference
