How to improve battery life of your Galaxy Note9 (fix battery drain issue)

If you think your Galaxy Note9 has a battery drain issue, you’ve come to the right article. This post will show you the tricks that you can try to better manage power consumption on your device.

Why your Note9 loses battery faster than expected

Fixing battery drain is a complicated issue and one that has no clear answer. This is true for any smartphone nowadays. When it comes to power management on phones, usage habits is the biggest contributor. Regardless of how big the capacity of the battery, the person using the device is usually the main reason why battery still loses power prematurely day in and day out. There are other factors of course and the most ones include these items:

screen brightness
minor OS bug
apps
inefficient coding
customizations or settings
widgets
hardware malfunction

Things to do to fix battery drain on your Galaxy Note9

We listed the common things above that contributes to fast battery drain on your Note9. We assume you’re familiar with them and already have an idea how to deal with them. Let’s discuss the particular steps that you can do to make it happen.

Refresh the system

Regularly rebooting your device is good practice. Like your typical computer that slows down when used continuously, your Galaxy Note9 can suffer hiccups too if it’s been running for a long time. Make it a habit to restart your device before you go to sleep to keep the system refreshed after a full day of usage. This trick is easy to do and won’t need more than a minute of your time. Here’s what you need to do:

Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for the device to restart.

Manage apps

The quantity and quality of your apps are some of the reasons for battery drain issue. Apps are built by different developers so the level of expertise, experience, and resources are often reflected on how their products perform. While many apps are free, they may not receive the proper updates on time because of resource constraints from their developers. Others may be done poorly in the first place and may lack the optimization tricks to work efficiently with a particular device. The more apps like these that you install, the higher the chance of them causing problems whenever they’re used, or even when they’re sleeping (not used actively). If you install apps on impulse and don’t screen them properly, some of them may be the main reason why the phone is regularly demanding CPU resources, which, in turn, puts pressure on the battery all the time. Apps designed to regularly display popups or ads can run continuously all the time. They don’t only annoy you but they can also be taxing the battery. Viruses and malware usually runs in the background all the time so even if you’re not using your phone most the time, it still loses battery constantly.

Even legit apps like Facebook, Twitter, and similar social networking apps are huge battery drainers as they constantly talk to remote servers to update contents or news feeds. As a user, you need to manage your apps well, especially if you want to extend battery life every day.

Keep in mind that there’s no effective method to really address battery drain issue. You must use a combination of tricks in order to lessen power consumption. You can’t rely on automated systems to address this problem for you. Managing your apps well by installing only necessary ones is a good idea.

Decrease screen brightness

The Galaxy Note9 has a really amazing 6.4-inch super AMOLED capacitive touchscreen. That means that it’s great to look at, especially when it’s on full blast. Well, that doesn’t come free though. In order to make that screen look great, the computer inside will have to work harder. And the more that it does that, the hungrier its demand for power is. If you keep screen brightness all the way to top, the faster the battery drains and the sooner you’ll have to charge. And that’s not all. If you leave screen brightness to maximum everyday, you’re significantly shortening the life expectancy of the battery itself.

Lithium-based batteries loses capacity the more it is used. That means that its ability to hold a charge everyday is getting shorter. Blame chemistry for that. As of this time, there’s no battery technology yet that can check battery decline so if you plan on extending the overall health of your Note9’s battery, one way of doing that is by easing screen brightness.

We’re not saying that you’ll have to sacrifice your eyes’ health though. Just try lowering brightness to the lowest comfortable level for you.

Install updates

Keeping apps and Android Operating System up-to-date is good practice. Not only does it lowers the chance of bugs from developing but sometimes, known problems are even fixed through it. Sure, sometimes, updates can also result to more problems but in general, developers releases new versions of apps and Android in order to improve things. Android is constantly evolving so unforeseen bugs may occur from time to time. It should not deter you though from installing updates.

Delete widgets

App shortcuts or widgets in your Home screen may be the reason why your Note9 is experiencing battery drain. Like apps, widgets may regularly contact remote servers to update its contents. Try to remove them if you still can’t figure out the cause of the problem at this stage.

Turn off services you’re not using

Some background services left enabled can slowly but surely drain the battery as well. Try going under Settings menu and disable any service or feature that can potentially add to the problem. You can start by disabling such things as Bluetooth, wifi, GPS among others if you’re not using them. If you are in an area with intermittent or poor cellular services, enable Airplane mode. If cellular signals come and go, it can cause the system to constantly search for them. Try using wifi instead to minimize battery loss over the day.

Clear cache partition

Android uses a set of temporary files to load apps quickly. These files are called cache. Sometimes, the system cache may become corrupted or outdated for some reason. This can lead to performance problems that often manifests in slow app loading or crashing. Overall, it’s not a good idea to have a corrupted cache so in order to ensure that it’s regularly updated, you want to clear the cache partition, where it’s stored, from time to time. Here’s how:

Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times to highlight ‘wipe cache partition’.
Press Power button to select.
Press the Volume down key until ‘yes’ is highlighted and press the Power button.
When the wipe cache partition is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

Use your phone smartly

Like in some other aspects in life, you want to use your phone efficiently, especially if you aim to minimize battery drain. If you are the type who regularly checks your device every after a few minutes throughout the day, you can’t expect the battery to last longer. Try to space out phone usage or better still, discipline yourself when to check the latest social network gossips or messages.

Factory reset

Wiping the device once every few months is another good way of minimizing battery drain. This is also a useful trick if done after a system update. If none of the suggestions above helped so far, consider doing this reset.

Create a backup of your data.
Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
Press the Volume down key several times to highlight ‘wipe data / factory reset’.
Press Power button to select.
Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
Press Power button to select and start the master reset.
When the master reset is complete, ‘Reboot system now’ is highlighted.
Press the Power key to restart the device.
