fully charged battery- no boot up

[chowceal1]

hey all, when i got this phone, i was told just a dead battery. put it on the charger and it never charged up. the screen just showed that i needed to charge the battery. i did the power & volume button trick, and the at&t logo showed up, then went back to dead. so i pulled the battery and tested it for charge. it came back 3.5. then i checked the charging port, and the contact part was broken. put in a new cable & port. still showing battery needs charging. got a different battery, still shows battery needs charging. only booting to at&t logo. what can i check or do next? thanx!

Honestly I wouldn't put any more money into repairing that device. It's almost 8 years old. You'd be better off buying something else newer at this point.
