Hard to say for sure. You should definitely try a different cable and perhaps even charger. You should also try cleaning out the charging port on the phone as sometimes things get stuck inside and can interfere with the cable and charging. Leave the phone plugged in for a little while and see if it's powering on and charging then. If not, it can be the battery (or potentially something like the port).hi. thank you
i plug in will try another cord
nothing but the black screen and flashing batt symbol
i was able to boot up but for 3 min.
i think pressing the cord hard helps but am not sure.
how can i tell if its port or battery
