How to Fix Samsung Galaxy S23 High System Storage Issue

Pinterest LinkedIn Tumblr

A few months ago, we wrote a guide on how to fix high system storage on Samsung Galaxy S22 devices, and we thought the system storage nightmare would end with the Galaxy S22 series. 

But after hearing many complaints from owners of the Galaxy S23 for high system storage, we knew the problem has somehow been inherited by the new flagship series. So we decided it is time to investigate about this issue.

In this article, we will explain why this happens and how to fix it. So keep reading if you want to learn how to fix the high system storage issue on your Samsung Galaxy S23!

Note: This guide can also apply to Samsung Galaxy S23 Plus and S23 Ultra.

What is The Average System Storage on Samsung Galaxy S23? What Causes High System Storage?

The Samsung Galaxy S23 comes with a minimum of 128GB of storage. That said, the average system storage of Galaxy S23 and S23 Plus would be around 30 GB – 40 GB. On S23 Ultra, this would be a little more than 40GB because it has the most features in the series.

Another thing that is worth mentioning is that devices that have a high storage capacity will also have high system storage than average models. So if you are using a 1TB storage Galaxy S23 device, you will see more storage (maybe even 70GB) occupied by the system.

But if your device’s system storage is much higher than the average usage (as shown in the image above), then it can be considered as “High system storage.” If you wonder why it happens, it is usually a glitch in the Android system.

High system storage usage can cause your phone to run slowly, lag during gameplay, and even lead to errors when trying to open certain programs. It’s important to fix the issue so you don’t experience any issues with your device.

Now let’s see the solutions you can do to fix this problem.

Fix 01: Restart the Device

Restart device

This simple step will help to clear up any software glitches that may have been causing problems with the phone’s storage analysis.

To restart your device quickly, follow these steps:

  1. Press and hold the power and volume keys together until the device turns off.

After restarting, you should notice an improvement in your device’s overall performance as well as a decrease in system storage usage. To check it, go to the storage usage section. If this did not work, don’t worry. Just move on to the next solution.

Fix 02: Clean Storage Using Device Care

Device Care, which can be found on the home screen and settings of your device, allows you to easily manage your Galaxy S23’s storage and clear any unnecessary data quickly.

So here, you are going to remove temporary cached data and any unnecessary system files by cleaning the storage.

To do this:

  1. Open Device care.
  2. Tap on the Optimize now button.

Check the storage after the cleaning is completed.

Fix 03: Allow to Read Total App Size in Storage Manager

Do you see an info mark next to a storage usage section when looking at the storage usage? If so, then this will probably fix the high system storage issue for you.

That mark on the usage section indicates that the system couldn’t analyze its usage. Therefore, the system simply adds the missing usage space to the system storage, causing it to increase and look like a problem.

So all you have to do is allow the system to rescan and adjust the system storage. Here is how you can do that:

  1. Open Device Care and go to the storage section.
Device care storage section
  1. Tap on the icon next to a storage section.

Once you have done this, you will see an immediate change in system storage and has fixed the issue.

Fix 04: Clean Device Care Cache

Device care is responsible for analyzing the system storage of your Galaxy S23. If it is glitched, then no matter what you do, you will keep seeing high system storage on your Galaxy S23.

To fix this, you can start by cleaning its cache. By clearing its cached data, you can get rid of the corrupted cache files, and fix the glitch.

To do this, follow these steps:

  1. Go to Settings.
  2. Tap on Apps.
  3. Scroll down and tap on Device care.
  4. Go to Storage.
  5. Tap on Clear cache.

Fix 05: Run App Optimization from Recovery Menu

Now that the device care cache has been cleared, it’s time to optimize apps. App optimization is a feature available in Recovery Menu mode, which can help fixing the Device care and even if there are any malfunctioning apps. To access this feature:

  1. Turn off your device.
  2. Plug a USB cable into the device.
  3. Press and hold the Power key + Volume up keys for a few seconds. When the recovery menu appears, release the keys.

Then, follow these steps to initiate the app optimization process:

  1. Use the volume down button and highlight “Repair apps.”

  2. Confirm.

Once it is done, highlight the Reboot device now and press the power button to reboot your device.

Fix 06: Software Update

Updating your device’s operating system will restore the system storage with new files, and it can free up additional space and clear out any unnecessary files or data stored under the system storage. Additionally, updates often come with bug fixes which could solve other issues as well.

To begin:

  1. Open Settings.
  2. Tap on Software update.
  3. Then, tap on Download and install.

So Before beginning the reset procedure, make sure you back up all of your important files.

Once backed up, go into Settings and do this to factory data reset your device:

  1. Go to Settings > General management.
  2. Tap on Reset.
  3. Under the reset menu, tap on Factory data reset.
