Help LG G3 Painfully slow charge after full battery drain

Hi there, I have a problem with my LG G3 and I would like to ask if you can help me. About two weeks ago the phone died when the battery ran flat and when I tried to charge it with the original charger it wouldn't charge, so I connected it to the pc and after several hours it started charging again. The only problem is that it only charges at a very slow rate now, both via pc and via wall charger(Original 1.8A and even a 2.4A one), by slow rate I mean it takes around 30 hours to charge from 0 to 100%. Having said that, the phone only seems to charge when it is first switched off. When I plug the phone to charger it does not detect it unless i first switch it off and only then it detects it and start charging. If i switch it back on when the charger is attached it still shows me that is charging but if I receive a message or two the battery starts draining all the same. I tried to change chargers/chords and i also did a factory reset and it didn't help. I now bought a new battery and it still didn't solve the problem. What I am suspecting is that the phone is stuck in slow charging mode that prevents fast charging when the battery is completely flat. Also if I try connecting the phone to the pc via usb, although it charges(after switching it off), the pc does not detect it.

Things I already tried and failed:
PC Charging
Wall Charging with Original charger and more powerful charger + changing multiple usb cables
Factory Reset
Changing Battery

Can someone please help!!

Regards

Christian
 
Sometimes, I get the "warning, slow charging" icon when I plug in use the stock charger that came with the phone. Usually, I just unplug the phone from the charger and then plug it back in and that usually fixes it.

Otherwise, it sounds like a hardware issue within the phone. How long have you had the phone? Is it still under warranty? That might be your only option.

I would blow out your micro usb socket with compressed air. Possibly the cable is not making good contact in the socket.

If that does not solve the issue (sounds like you tried everything), next I would try holding the cable into the socket for a few minutes to see if the charging rate improves. An app like Amphere (free at the play store) may help you during these tests. Good luck.
