Sometimes your Samsung Galaxy Note 9 battery drains rather fast and it may overheat when you put it to charge. In this tutorial, you learn how to troubleshoot and fix Galaxy Note 9 battery drain and overheating issues.
Tips To Fix Galaxy Note 9 Fast Battery Drain
- Disable Bixby. Why? “Bixby” has to constantly auto-connect to get the latest news, app information, location, etc. This, in turn, drains your Galaxy Note 9’s battery.
- Uninstall RAM cleaner apps. Why? The constant moving of data back and forth from and into your RAM storage puts a strain on the Note 9 battery and system.
- Disable LTE. 3G networks are still fast. 4G/LTE requires more resources to function.
- Adjust Backlight Brightness. Try not to use more than 60% backlight on your Galaxy Note 9. The higher the brightness settings, the more battery power your phone has to use.
- Disable S-Health and S-Voice. Trackers are great. However, they collect data 24/7. Once enabled, they use your battery and increase battery drain.
- Disable Pop-ups and Notifications. I refer to Twitter, Facebook, etc notifications. Each time you receive a game or app notification, you use up the remaining battery life on your phone. Try disabling the ones you absolutely do not need.
How To Fix Bad Samsung Galaxy Note 9 Battery Life
This article continues by addressing the battery draining issues, the possible causes, and fixes. After, the article addresses the issue of overheating, the causes, and solutions. Time to learn what to do if your Samsung Galaxy Note 9 battery drains fast.
Use An App To Reduce Galaxy Note 9 Battery Drain
Firstly, I would ask the question! I know you want to ask. Didn’t you say that apps affect battery life? Yes. Yes, I did. However, this app helps you save battery life on your Samsung Galaxy Note 9.
Greenify is not your typical battery saver app. Unlike most of these types of apps, Greenify does not add unwanted apps and popup ads on your Galaxy Note 9. Greenify is entirely unobtrusive. It does what it set out to do. Help you regain your depleting battery life.
Greenify allows you to place most of your apps in a state of hibernation. Apps placed in hibernation only reactivate when you choose to take them out of hibernation. All you have to do is launch the app you want to use.
After you finish using the app, Greenify places the app back into hibernation after a period of inactivity. Greenify reduces the number of apps that run in the background. Hence, your battery life improves significantly.
Are you interested in using Greenify? Then, read how to use Greenify app to extend battery life on your Samsung Galaxy Note 9. Once you understand how to use Greenify, then check out the other optimization tips for maximum battery life. Alternatively, check them out right now if you do not like the idea of using apps.
Change Samsung Galaxy Note 9 Settings
Firstly, turn off the automatic brightness feature. This feature is the first to modify if you want to extend you Note 9’s battery life. Instead of automatically adjusting the brightness, set it manually.
However, do not set it so low that you no longer have visibility. Reducing the brightness level of your Galaxy Note 9significantly reduces the strain on your battery.
Location Services & GPS
Secondly, turn off the GPS. Yes! Do you know how many apps use the Note 9’s GPS in the background? Location Services is one of the most power consuming features of the Galaxy Note 9.
You may think that Google Maps is the culprit. I did for quite some time. However, social media apps like Facebook, Twitter, and WhatsApp use your Galaxy Note 9’s GPS functionality. This usage, in turn, drains your battery life.
Moreover, while location services are useful for finding places/directions, I doubt you want Facebook or the likes tracking you. By limiting the GPS & location services, you boost you Galaxy Note 9’s battery life.
Do you know how to modify location services? To adjust the location services on you Samsung Galaxy Note 9, do the following:
Tweak GPS Settings To Improve Samsung Galaxy Note 9 Battery Life
Go into Settings > Location > Mode, and you find three options: High Accuracy, which uses GPS, Wi-Fi, and the mobile network to determine your position. The high-accuracy mode drains the most battery life.
Battery/Power Saving reduces battery usage. However, your GPS functionalities may not be accurate. Finally, there is Device Only. Device Only uses the onboard GPS of your Galaxy Note 9.
Furthermore, you can disable location services altogether. However, as you would expect, this limits your Note 9’s capabilities. Adjust the settings to your liking. For me, I use the power save mode. However, if I go for a jog or walk, I momentarily enable the High Accuracy setting.
Modify Sync Settings On Galaxy Note 9 To Stop The Battery From Draining Quickly
The third setting that you can tweak is the Galaxy Note 9 Sync setting. As you know, sync allows your Note 9 to receive push notifications and updates. Hence, when you disable individual sync features, you prevent unnecessary notifications and updates.
However, for important notifications, you can choose to allow sync to work. The choice is yours. Also, note that you can manually refresh or sync each of your apps by opening them.
Turn Off Background Sync
Depending on your apps, this may or may not impact much. If you have at least five apps that sync in the background, chances are they are the primary reason why your battery power can never stretch longer in a day. If you really don’t need the syncing, go under Settings>Accounts and turn them off. Switch to manual sync whenever you need an update for, say, emails.
Lastly, explore the battery settings on your Samsung Galaxy Note 9. Get a feel for what is using up your battery life and take steps to reduce the load on the battery. Android devices have lots of settings that can reduce battery drain. Check them out!
Check To See Which Apps Are Draining Your Samsung Galaxy Note 9 Battery
Go into Settings > Device Maintenance > Battery. There, view what’s making your Samsung Galaxy Note 9 battery drain very fast – Moreover, if you tap on each of the apps, then tap save power to prevent those apps from using battery power when not in use.
In the settings, you can also select a power saving mode such as MID or MAX. Each setting disables or adjusts certain features to extend your Note 9’s battery life.
Customize these features to your liking for optimal battery performance on your Samsung Galaxy Note 9. However, none of them are mandatory, and you will know what works best for you.
