does your phone have any physical damage to it?

when you take the battery off, is there water damage to it? (is the indicator fully pink or red, instead of Xs on a white background?)

the first thing you may want to try is to replace the battery...
this phone is already obsolete, so you may have a difficult time finding a battery, but when you do, it should be cheap.

however, the chocolate 8500 is one of the most notorious phones when it comes to problems. it appears that the charging port is actually working, as you are able to get the phone to do something when plugged in...

remember in the future to always download backup assistance (this is free as long as you are signed up for my verizon) as it will save your contacts online and you will be able to re=download them onto a new phone if anything were to happen
