Phone doesn’t charge ¶ 

It takes longer than normal to charge, if at all, or phone doesn’t recognize when charger is connected.

Battery is installed incorrectly ¶ 

The phone may not charge because the battery has been installed incorrectly. This could be the issue if your phone doesn’t charge, and if it doesn’t power on either. Let’s try removing the back cover, and reinstalling the battery. LG G3 Battery Replacement

Battery is bad ¶ 

If the phone has been using the battery for a while, or if the user has used heavy applications on the phone it may cause the battery to heat up. If the user forgets the charging cable plugged in all night it will weaken the battery, especially if it was charged for a full night over multiple times.

This is an easy enough fix. Start by removing the back cover. LG G3 Battery Replacement

Sensor pads can become loose and become misaligned with the button you are trying to press. This requires that you replace the sensor pad.

This morning I found my G3 unresponsive when turning on.

I figured the battery must have depleted, and tried to charge it but it does not turn on even after an hour.

I tried removing the battery and memory card and holding the power button for 15 sec and plug the charger back in, but still no charge.

The red LED that usually turns on on upper right corner of the phone when charging does not light up.

Any suggestions?

I have being using my LG G3 for about two years now but I started to experience battery issues and was forced to replace it. Thereafter my phone can't last after three calls before shutting down after power drainage. I'm helpless...

The QI wireless charge doesn't work anymore. Already tried to replace rear cover (with QI coil). Now what is the spare part to replace? Main Board?
