If you are experiencing any charging issues on your Samsung Galaxy Note 8, these tips may help you fix them. These tips have been compiled from various users who have been through slow charging and other problems, but have managed to fix them.

Solution #1 – Make sure your Charger is working

Sometimes, the main culprit of having slow charging or no charging at all is a broken charger. The best practice is to use the charger that came with the Note 8 out of the box. If you don’t have that or you are experience slow charging on it, you should buy a replacement from Samsung. Also, do note that the device should say Fast Charging on lock screen when connected to the proper charger.

Solution #2 – Replace USB Type-C Cable

After checking the charger itself, you should also check the cable. These new Type-C cables have to adhere to large amount of power flowing through them so its not illogical to think that the cable might have been damaged. You can check whether the cable is the culprit by replacing it with a new replacement.

Solution #3 – Clean USB Type-C Port

As we carry our phones in our pockets most of the time, there are chances that lint has been trapped in the actual port hence not allowing a proper connection. You can inspect the port by using a flashlight and if you find any traces of dust particles or lint, try to remove them with a wooden toothpick or something that isn’t metal as the connection port is quite fragile.

Solution #4 – Make sure the Outlet has Power

Every charger that is shipped with the Note 8 is conforming to a certain region’s standard. If you are travelling to another country and trying to charger your phone from a outlet, make sure your charger is complying to the country’s voltage standards.

Further, it sometimes occurs that the actual outlet you are using is faulty and switching to another one might fix the issue so definitely give that a try.

When your phone is idle in a pocket or kept on a table, it keeps on pinging Google services to collect your location data.

Solution #3 – Disable Synchronization of Services Not In Use

When you add a new account to your phone, all related services start syncing automatically. For example, if you add a secondary email account on the Samsung Galaxy Note 8 and you only use Gmail with it. However, your phone will also enable Google Photos, Maps, Google account, Google Contacts etc. This uses battery when your phone is not in use.

Solution #4 – Disable Samsung Galaxy Apps Store and Updates

Samsung has its very own Galaxy Apps store that allows you to download Android apps and games. Using this app, several of Samsung system apps are also updated. And most promotional games can be downloaded for free from the Galaxy Apps store. This app runs in the background to check for app updates, and then downloads and install these updates automatically on your phone. Samsung Galaxy Apps may also use your battery if you are around a slow WiFi or data connection as it would keep on trying to download the updates.

Further, Samsung is moving most of it apps to the Play Store so that this problem is addressed. In one instance, your phone might start downloading apps from the Play Store along with updates from the Galaxy Apps Store hence straining the CPU and all other hardware twice as much. It is a good idea to disable the Galaxy Apps Store completely and check back manually to see for any updates.

Solution #5 – Factory Reset Phone
