How to add more RAM to your Android device with a MicroSD card

Your Android device will likely come with 64GB (or more) storage, but it’s the RAM that really affects what you can do with it. Most high-end Android devices ship with 2GB or more of RAM, but some of the cheaper devices may have only 1GB of RAM or even 512MB in some cases.

But can you add RAM to the phone in the same way that you can do while using a computer?

Why does your phone need more RAM?

The importance of additional RAM cannot be overstated.

While the larger storage space gives you more storage space for media and apps, the additional RAM helps the processor to run faster. This helps create and play media as well as run apps and games more efficiently.

For example, some issues with playing some games on a slow internet connection are mistakenly blamed for some issues. In fact, it can be accelerated with additional RAM, rather than a faster wireless connection.

How does the swap file increase the RAM of the phone?

On your desktop or laptop computer, you can allocate a portion of your hard drive space to increase your RAM. This is known as a swap file and takes advantage of the available space on your hard drive or solid state storage medium when RAM becomes full. Instead of discarding the data, it is stored on your drive.

Windows 10 has advanced swap file management which means you never need to adjust settings. However, if you do, you will be able to increase the portion of your hard drive that is dedicated to the purposes of the swap file.

The same can be done on Android to increase RAM effectively.

While the basic principle is the same, the implementation steps are different on Android. You’ll need a dedicated app to make the trick work. You will also need to root your device.

By default, some files and permissions are blocked in Android. By taking advantage of root powers on the device, you can control the entire operating system and internal components. This enables you to access files and devices that are otherwise restricted, as well as install and run specialized applications.

Although rooting is easier than it used to be, it can be a challenging process. But if you want to increase the RAM on your Android phone or tablet, it is necessary to root the device first.

What you need to increase RAM on your Android phone

Using the swap file method to increase RAM on Android has three main components:

  • High quality microSD card (Class 4 or higher is best).
  • Android phone or tablet.
  • Swap file management application.

While rooting Android is simple, it may not be enough. Some phones (eg Xiaomi Redmi Note 4) limit the swap file size at the kernel level. This means that no amount of root and toggle file manager will increase the RAM on your Android device.

Instead, you will need to buy a new phone.

To save time checking if you can increase RAM for Android manually, use the checking app. A good example is MemoryInfo & Swapfile Check.

to download: MemoryInfo & Swapfile Check (Free)

Just launch the app and tap Start the RAMExpander test Here to start checking out. If the swap file can be incremented, the app will indicate this with a “Congratulations” message, along with the maximum possible increment.

You will notice that this is a useful tool that also lists many RAM and storage details.

Choose a good quality SD card to increase RAM

If your phone or tablet’s swap file can be modified, it’s time to consider your phone’s microSD card. As mentioned above, this card should be fast and flexible.

Don’t just buy any old microSD card. Instead, spend a little extra money on more flexible storage, which leads to better reliability. Select the rating in the box when buying a new microSD card — Class 4 is recommended as a minimum, but Class 10 is best.

And be sure to watch out for fake microSD cards. Poor quality SD cards bring many flaws to your Android phone

Beware: Using an SD card to increase the RAM in your Android device will shorten the lifespan of your media.

It is important to note that some phones will not allow external storage (your microSD card) to be used for the swap file. However, if your phone has enough internal storage, it can be used instead, but its life can be reduced likewise.

Apps to increase RAM on Android phones and tablets

While it is possible to manually select the swap file on your Android device, you may find it easier to use an app:

Note that these are all ad-supported options.

All applications work the same way:

  • Run the application.
  • Create a swap file.
  • Specify the desired swap file size.
  • Choose where to save the swap file (external microSD card or internal storage).
  • Wait for the swap file to be created.

You may need to restart your phone after you are done to configure the swap file.

Remember to leave the app installed for as long as you need to run the swap file.

Don’t have root privileges? Practice better Android memory management

If your phone cannot be rooted, or if your phone manufacturer has placed restrictions on managing manual swap files, all is not lost.

Gaining a better idea of ​​Android memory management can make it seem as if you have increased your RAM without doing so. This includes things like using lightweight versions of apps, uninstalling apps you no longer use, and avoiding things like RAM boosters and stopping tasks. These steps don’t work quite as described—if anything, they’re running in the background, actively using RAM!

Does increasing RAM improve Android performance?

If you succeeded in allocating a portion of your phone’s SD card to RAM, you should get instant results. If you are a keen mobile gamer, you must find that previously incompatible games will now be played.

Beyond that, the device should be more useful and productive than ever before. However, this comes with some trade-offs.

Now you need to monitor your storage. The storage is now essentially smaller than before, thanks to the swap file customization. With less space allotted to files and media, they will fill up faster than expected. Avoid this by keeping your data synced with your preferred cloud storage.
