How To Fix LG V20 Won’t Charge Or Have Other Charging Problems

Not charging issues are among the most commonly reported problems with smartphones today and the #LG V20 (#V20) is no exception. In fact, we already received some complaints from our readers requesting assistance as their devices would no longer charge its battery like it used to. The South Korean phone maker has always been so consistent with the quality of its devices and so far, there was no incident that may tag the V20 as a sub-standard device. It’s not perfect and there might be some manufacturing issues with some of the units but when it comes to the battery, the V20 is good.
In this post, however, I will address the not charging problem with the LG V20. It could happen to you, it could happen to anyone who owns a smartphone. Below are some steps you can follow to thoroughly troubleshoot your phone that would no longer recognize the charger being connected let alone charge the battery. Read on to understand more about this problem and learn how to fix it.

Troubleshooting LG V20 that’s not charging

The purpose of this troubleshooting guide is to determine what the problem with your phone is and come up with a solution or workaround that will let you continue use the device even if the charging process fails sometimes. In this case, this is what you’re going to do:

Step 1: Verify it’s not a system crash issue by pulling the battery

This is a very straightforward step, it’s simple, it’s easy but also very effective. The moment you plug your phone and it won’t respond to the charger, turn your device off, if it’s powered on, and then remove the back cover and pull the battery out.

While the battery is out, press and hold the Power key for a minute. After that, replace the battery and put the back cover on. Then, turn the phone on and try to charge the phone again.

The reason behind this step is to make sure the firmware is responding as it also plays a great role in the charging process. It’s actually the one responsible in making sure correct voltage and current is flowing through the circuits. Without it or if it keeps crashing, the phone may not charge properly or not at all. The battery pull procedure is very effective in addressing minor firmware issues.

Step 2: Make sure your charger is plugged into a working power source

If the phone won’t charge after doing the battery pull procedure, then make sure your charger is plugged into an electric outlet that works. You can just unplug an appliance that you know is working properly and plug the charger into the outlet.

In case the problem persists, try to do the next step.

Step 3: Connect your LG V20 to a computer or laptop if possible

The purpose of this step is to make sure verify if the USB cable is working properly or to know if it’s broken. It is important that you rule out this possibility first since the USB cable is the only thing that bridges the phone and your charger.

If the phone shows it’s charging or gets detected by the computer, then the cable is good and it’s most probably an issue with the charger. However, if the computer cannot detect the phone or if the latter still won’t charge, then continue your troubleshooting.

Step 4: Physically check the charger for debris or lint in the port

You don’t have to do much. Just try to look into the port on your charger and check if there’s a debris, lint or corrosion that might have prevented the phone from charging due to improper or no contact at all.

As for the debris or lint, you can just fish them out but when it comes to corrosion, all you need is a blast of compressed air. In case there’s a bent pin or connector, attempt to straighten it out with a pair or tweezers.
However, if the charger doesn’t show any abnormalities and if it’s possible to use a different one, try to do so just to find out if the phone charger with other chargers.

Step 5: Check the cable for breaks and corrosion on both ends

Run your fingers through the USB cable and try to feel any abnormalities such as lumps or breaks. If the cable is perfectly fine, you wouldn’t feel anything unusual. Once you’ve verified that the cable is fine, try to check both ends to find out if something is preventing the connectors from making proper contact.

If the cable is fine, then try to use a different cable that has the same specs with the original if possible. If that works then you should buy a new charger kit for your LG V20.

Step 6: Check your phone’s USB / charging port

After inspecting both the power adapter and USB cable, you should check your phone’s utility port. Try to find if there is a debris, lint, bent pin or corrosion. These things may disrupt the charging process.

If the phone suffered either physical or liquid damage, then there’s always a valid reason to think the circuit that is connected to the charging port got affected. Sadly though, we really can run tests that may confirm this. So, try to rule out another possibility before you seek assistance from a technician.

Step 7: Try a different battery

One of the good things about the phones that have removable batteries is that you can always buy a spare. While we don’t know at this point what the problem with your phone is, there’s always a possibility the battery got damaged especially if the phone suffered liquid damage or if the problem occurred without apparent reason and the phone shut off on its own.

If possible, borrow a battery from someone with the same phone or you can go to a local shop to try a different battery.

Step 8: Seek assistance from a technician

If all else fails, it’s time you sought assistance from someone who can do some tests to confirm if the problem is with the firmware or hardware. Should the problem is found in the hardware, it’s more likely a manufacturing defect especially if the device didn’t suffer from both liquid and physical damages.

  1. My phone was on 57% then out of no where it just shut down by itself. I got it to turned back about 5mins later and the battery was at 4%. Now my screen is black and my phone won’t charge or do anything. Please can you help me I would really appreciate it. Thanks

  3. My LG V20 will not charge properly when connected to USB. Even though it shows a positive mA flow the battery level continues to decline. Charges great on AC Charger (both rapidcharge and standard)

  4. My V20 only charges to 92%. I’ve reset the phone, I’ve tried different charging devices….still 92% max charge.
