How To Fix Samsung Galaxy Note 3 Not Charging – Troubleshooting Guide

The Samsung Galaxy Note 3 is still one of the powerful phablets available in the market today but if it won’t charge, then it will become useless if the battery is drained. When troubleshooting a phone that won’t turn on, it is very important to verify if the device still charges because the reason it’s not turning on is may be because the battery is just drained.
In this post, I will guide you through troubleshooting a Samsung Galaxy Note 3 that won’t charge. This is also an answer to the questions sent by our readers in the past who were asking for our assistance. The steps I used in this guide is the same as the steps we technicians use when troubleshooting the same actual problem only that we can’t physically inspect the phone.

How To Fix Samsung Galaxy Note 3 Not Charging – Troubleshooting Guide

The main purpose of troubleshooting is to know what the problem is and what causes it. It doesn’t guarantee a fix but information. Once you have the details of the problem, you can find ways to work around it.

Step 1: Plug the charger in and allow the phone to charge

If the phone is still on, plugging the charger in will tell you immediately if it charges or not or if the device responds when the cable from an active charger is plugged into its charging port; the usual charging icon will show. On the other hand, if the phone is off, the LED indicator will tell you if it charges or not.

Step 2: Check the ports and connectors

Corrosion will interfere with normal charging process that is why it is necessary to check if the charging port is corroded with dirt or other debris. Just by looking directly into the port will tell you if there’s some debris stuck in it. One way to make sure it’s clear is to get a small brush, insert the bristles in and start the brushing motion.

Once you’re done checking the port on your phone, check both ends of the USB cable you use in charging. Cleaning both ends will also help. Lastly, check the port on the charger and clean it like you did on your phone. After doing all these, attempt to charge the phone.

Step 3: Verify the charger still works

The easiest way to do this is to use a different charger and see if the phone responds to it. If so, then your charger needs replacement, otherwise, there’s more to the problem than a busted charger.

If using a different charger is impossible but you have other devices, then try charging them using your charger and see if they respond to it. If they don’t, it doesn’t actually mean the charger is busted. It could be the cable you use.

Step 4: Verify the USB cable isn’t broken

Using a different USB cable is the most effective way to determine if the original is broken or not. The cord bridges the charger and the phone so if there’s a break somewhere, current can’t be conducted.

The Note 3 uses the USB 3.0 cable but you can actually just use other cables that support USB 3.0. Or if you know someone with the Note 3, borrow the cable and try it on your phone.

Step 5: Verify the battery is properly mounted and working

Remove the back cover, pull the battery out and try cleaning the connectors. Begin by inspecting the connectors at the back of your phone. See if there’s a bent pin that may not make good contact with the battery’s connectors. Moreover, get a dry cloth and wipe the connectors on the battery just to make sure there’s no corrosion.

After the cleaning, place the battery back in and make sure it’s properly mounted. Secure it with the back cover and attempt to charge the phone. If still nothing, then it’s time you sought help from a technician.

Step 6: Send the phone in for repair

If all else fails, it’s safe to assume that the problem is with the hardware. Seek help from a technician who can physically and thoroughly inspect the phone for hardware faults an all. If it weren’t the hardware that’s causing the problem, the firmware may have something to do with it but then again, it’s beyond your grasp.

Charging issues aren’t just hardware problems. The firmware also has something to do with it since it detects the current and controls its flow into the battery while turning on some components (like the LED indicator) and showing the charging signs.

  1. My Note 3 is draining the battery when a charger is connected; instead of charging the device , it drains the battery and it will be heating up.

  2. I am the same as Francis, my phone seems to be rejecting the battery as the initial charge icon will come up but then disappears and reappears over and over seemingly doing nothing.

  3. My Samsung Note 3 with android 6.0.1 and with marshmallow has been rejecting battery, when the phone is off, and i insert the charger, the battery charging icon will only be coming and going off, a kindly flashing the battery charging icon and it continues this way. If i insert another battery it charges. Does it mean it is selecting battery?

  4. You left out one of the simplest options, restart the phone. My note 3 has stopped charging by Qi a few times and rebooting has always fixed it.
