Why my LG G3 doesn't charge when plugged in?

[AC Question]

I tried to charge my phone as I do everyday on my bed charger, my phone was at 1%. So I plug it in. The only thing is that time it seemed to have poor connection in the charge port. I kept hearing the notification sound of charging and not charging repeatedly very fast like 0.1 s interval. The phone went off, no more juice. Since the connection was bad I decided to try another cable, and it did the job. As it was off it charged very well. I waited 15 min. At 10% I decided to turn the phone on and leave it plugged to use it. The thing is, it is not charging anymore when it is on. I tried 8 cables 8 chargers nothing will do. I did a factory reset to no avail. I know the port is good because when the phone is off it charges perfectly. I figured I busted the charging circuit with the poor connection event. What do you think?

Perhaps the battery is on its last legs?

Thanks for your reply pugs, have you ever seen such a behavior in case of an old battery? I will try my friend's G3 battery in my phone soon. In case that doesn't work I think I'll have to resort to change the motherboard. I'm just trying to see if anyone has seen any precedents on this story.

Can you buy a second G3 with a cracked screen and take its motherboard to replace yours?

Yes, a failing battery can react in odd ways. A motherboard transplant can be done but my guess it's the battery. Let us know how you get on.

Like Pugs said, the battery is the first suspect! Ppl are far too eager doing factory resets, they are a last resort and are highly inconvenient. Things go wrong, ppl forget passwords etc... You could also have a faulty socket where you plug in the charger... Take it to a repair shop would be my suggestion...

Yesterday I plugged my cellphone and it magically charges normally now.... I don't know how...I havn't changed any of the conditions: same charger, same cable same wall socket...
The phone socket was fine since it charged perfectly when the phone was off. The battery still lasts a complete day with intensive use so it's not faulty... It's a miracle
