How to resolve Note 4 not charging problems: The Samsung Galaxy Note 4 is perhaps one of the best tablets on the market. Like most gadgets these days the device is prone to relatively minor and easily fixable issues. This guide will teach you what to do when your Samsung Galaxy Note 4 won’t charge or turn on.
As a former Galaxy Note 4 owner, I too was faced with the ever annoying slow charge or sometimes my Note just didn’t charge at all. Today you will learn about four possible solutions to fix a Samsung Galaxy Note that won’t charge.
Here is a great article to read if your Note 4 battery overheats or drains too fast. For now, you can continue with this article if your primary purpose is getting the Note 4 to charge properly.
Things you should know about charging the Galaxy Note 4
Don't charge your Note 4 near water or in excessively hot or humid conditions. Also, do not overcharge your Note 4; charging overnight when your battery only needs two or three hours is a bad idea and leads to a battery exploding or damaging your Note 4. Your device has a cut-off switch for your battery, but sometimes this doesn't work. Always make sure that you charge your phone for no more than the amount of time required.
If you're replacing your Galaxy Note 4 charger or cable, be careful: there are many cheap third-party chargers that went bang in the middle of the night or turned smartphones into toast. As with any electrical equipment, make sure that anything you buy complies with all the relevant safety standards. A super cheap eBay offering from an obscure Chinese supplier doesn't necessarily sound like a good deal regardless of the price.
Use the correct charger for your Note 4
Make sure that you are using the Samsung charger and cable that came with the Note 4 device. Other chargers may have different voltage ratings, and they won't always work with the Note 4. Purchase an official Note 4 charger on Amazon.
Also, if your charger doesn't seem to be delivering the right charge frequency, check that it's the right one. A charger from another device might not provide the right amount of power— for example, a charger for a Bluetooth headset won't put out as much power as one designed specifically for smartphones. In the case of recent high-end phones, you might have a phone that supports fast charging but a charger that doesn't deliver it. Buy fast chargers for the Note 4 here.
Ensure that you leave your device charging for a while before attempting to use your Note 4
Sometimes your battery may become completely drained, and it may take a while before the charging takes effect. As a precautionary measure, leave the device plugged in for about 30 minutes before you try to turn it on.
Check your Wall Sockets
Change the wall socket and use the cable and charger on a different device to make sure that there are no faults with the charging apparatus. Try a different charger and cable with the same voltage.
Note: Charging from a wall socket will always charge faster than via PC or laptop because computer's' USB ports don't deliver very much power. A wall outlet can provide twice as much power than a USB port can, and in the case of fast chargers, it can give as much as five times the power — which means much, far more quickly recharging.
Charge the Note 4 via USB/PC
Try plugging the Note 4 into a USB port on your PC or laptop. Although, it will charge much more slowly using the USB port than from the charger plugged into the wall.
Consider charging the S6 wirelessly
Try charging the S6 using a wireless charger. You can find wireless chargers here. Wireless chargers are good replacements in this case because they charge your device without needing to connect to the port.
Check the Charging port on the Note 4
Inspect the Galaxy Note 4 charging port; the charging port ends up choked with many things after being chucked in a handbag or pocket. A can of compressed air can blow out the offending irritants and get your USB connection back to normal. If you don't have access to canned air, then you can try blowing (not spitting) into the charging port.
Galaxy Note 4 DIY USB port fix
One of the quickest, easiest, and often most successful solution, is to do a little DIY repair on the hardware of you Galaxy Note 4. The problem is that the metallic surfaces inside the USB port, and the microUSB charger are not making proper contact, either through a manufacturing defect or because of the continual plugging and unplugging of the charging cable severed the connection. If you want, buy a Galaxy Note 4 Charging Port and take it (along with your Note 4)to a repair shop to install the new USB port.
You need to do is shut down your device,
Remove the battery (if possible) and use something small, like a toothpick, to 'lever up' the little tab inside the USB port on your Galaxy Note 4.
Do so very carefully and gently, then reinsert your battery (if you had to remove) and plug it in again. Nine times out of 10 this is all that is required.
Update or rollback the OS on your Note 4
Software updates and new Android versions can play havoc with your battery life, especially when upgrading an old device to current software. Newer devices are often optimized to take advantage of the latest software, packing bigger batteries and pre-optimized hardware, whereas your two-year-old device can struggle when it makes the jump from behind the pack.
If this happens to you, consider rolling the device back to an earlier Android version, though be warned that this carries security risks. (The latest software versions are always recommended to keep your device protected, and while the risk of operating your smartphone on an older version is often negligible, it’s worth noting.)
Similarly, sometimes device battery life significantly improves thanks to an update, as seen with the Moto 360 smartwatch, so if you're behind on your Android software version, head to the 'about device' page in your settings and check for an update.
Note 4 not Charging? Switch off your Note 4
Using battery intensive apps/features while you are charging your device will affect how fast it gains battery life. If you are charging while Skyping somebody at full-screen brightness, the device will naturally take longer to charge than when locked with Wi-Fi and 4G turned off. Switch the device into airplane mode, or off completely, when you are charging if you want to see the fastest energy boost.
If it still isn't working, then you may have a dead battery or a broken charging port. Contact your retailer, carrier, or Samsung and find out what your options are.
If you're out of warranty, then you can try buying a replacement battery, or even replace the charging port yourself. (If you don’t know what you are doing, then it is probably best to take the device to a professional and have the tech perform the repairs for you).
