When the memory runs low, your phone will run slowly, the battery drains quickly, and limit the tasks you can do. By deleting unnecessary data on your mobile phone, you will have more free memory space and increase productivity for your device.

Steps

Method 1 of 2: On Android

1. 

   Identify which apps are taking up the most memory. You can check the health of your phone to see how much memory (RAM) is in use and which apps take up the most space. Note: RAM is used memory, so just having a little unused RAM is not an alarm. Android always tries to put the majority of free RAM into use because this is the most efficient way of consumption.
   • Open your device's Settings app.
   • Scroll down and tap "About phone".
   • Click the "Memory" option. Some basic details about phone memory usage appear.
   • Click the button "Memory used by apps". The apps that use the most RAM will appear.

2. 

   
   
   Delete old apps. Deleting unused apps will increase the amount of free space Android has, as well as free up RAM if there are many apps running in the background. Both the free storage and RAM will help to improve the performance of the Android device. Apps that you have purchased or received for free can be re-loaded at any time from the Google Play Store.
   • Open your device's Settings app.
   • Select "Apps" or "Application manager".
   • Scroll down the list to find the apps you don't use.
   • Click the app and select "Uninstall" to remove it. The app will be removed from the device. Without the "Uninstall" button, it means the app is built into the device and can't be removed.

3. 

   
   
   Disable apps that you don't use but can't uninstall. Many Android devices often come with dozens of pre-installed applications running in the background and occupying system resources. These apps cannot be uninstalled if the user does not take root access to the device, you can disable them instead. Although not freeing up memory space, but these applications will no longer launch.
   • Open your device's Settings app.
   • Select "Apps" or "Application manager".
   • Find the application you want to disable. Usually they are vendor applications or bundled applications that you do not install yourself.
   • Click on "Uninstall updates" if available. You may have to press this button first to get the option to disable the application.
   • Click "Disable". The app will be shut down and no longer launched.

4. 

   
   
   Transfer images to computer or cloud. If the image takes up a lot of memory on Android, you can transfer the data to a computer or upload to a cloud storage service to free up space on your device.
   • Switch to PC - Connect your Android device to your computer via a USB cable. Open the Notification panel, click the USB option and select "Photo transfer". Open the Computer / This PC window, right-click on the Android device (which may only display the model number) and select "Import pictures and videos". Follow the instructions to copy all photos on the device into the Pictures folder. Click the "More options" link and check the "Delete files from your device after importing" box.
   • Transfer to Mac - Connect your Android device to your Mac computer via a USB cable. Open the Notification panel, click the USB option and select "Photo transfer". Open the Image Capture app on your Mac and select your Android device in the menu on the left. Open the additional options at the bottom of the menu and select "Delete after Import". Click "Import All" to transfer all photos from your Android device to your Mac, then delete the photos from Android.
   • Cloud upload - Download the Google Photos app if you haven't already. Google Photos lets you back up all your photos for free with just a little bit of quality loss, or upload photos to Drive storage in original quality. Open the Google Photos Settings menu and tap "Back up & sync". Click "Upload Size" to choose whether you want to use free storage or Drive. As long as you make sure the option "Backup & sync" is enabled, the photos will be uploaded automatically. Then, click "Free up space" from the Settings menu to delete all the photos you just backed up.

5. 

   Delete the file in the download folder. If you still need to free up more memory, you can delete the content in the Downloads folder. This folder usually contains PDF files or other formats that you only download to your device and use once.
   • Open the Downloads app in your app drawer app drawer. The app drawer button has a grid of dots.
   • Click the "Delete" button and select all the files you want to delete.
   • Click "Delete" again to delete all the selected files. Note: the process varies slightly by phone manufacturer.

6. 

   Replace RAM-consuming applications. If something on your phone is consuming a lot of resources, try to find some alternatives. For example, instead of using the Facebook app, you can visit the Facebook website. While some features may be missing, you will save a lot of system resources.

7. 

   Stay away from apps that claim to free up RAM. There are many apps on Google Play Store that advertise that can increase system performance. Depending on how Android is designed, these apps are rarely effective, sometimes even impacting performance rather than improvement.

8. 

   Update system software. Newer version of system software can improve device working performance. These versions sometimes come from the carrier, and sometimes the new version may not be compatible with the old device.
   • Open your device's Settings app.
   • Scroll to the bottom of the menu and select "System updates".
   • Click on "Check for update" and install the update (if available). The update usually takes about 20 minutes if there is a new update available.

Method 2 of 2: On an iPhone

1. 

   Restart iPhone periodically and often. A complete restart of the iPhone will reset the system memory. In addition to fixing apps that are not performing properly or consuming too many resources, this process also improves the overall performance of the device.
   • Hold down the power button until the Power slider appears on the screen.
   • Use your finger to swipe the slider to power off iPhone.
   • After about 10 seconds, press and hold the power button again to turn the iPhone back on.

2. 

   Reset iPhone RAM. You can apply this quick tip to clear RAM on iPhone, making it easy for apps to have more free RAM to use:
   • Hold down the power button until the Power slider appears. But first you need to make sure your iPhone is unlocked.
   • Hold down the Home button for 5 seconds after the slider appears. If successful, you will be back to the Home screen. The RAM that is being used will be cleared.

3. 

   Delete unused applications. IPhone performance will be better if the phone has some free space available. One of the easiest ways to free up memory is to delete apps that you no longer use. As a result, the memory and RAM for applications that normally run in the background will be freed. You can re-download any app for free or purchased from the App Store.
   • Find the app you want to remove on the Home screen.
   • Hold down on the app until the icon starts to wiggle.
   • Click the "X" on the corner of the application to delete. Repeat with any other application you want to delete. Note: system apps won't be able to delete them.

4. 

   Transfer pictures that you have taken to your computer. If you've taken a lot of photos, the space on your iPhone may fill up. When the memory runs out, the system becomes sluggish. This image transfer process will be different depending on the computer you use:
   • For Windows - Connect your iPhone to your computer via a USB cable. Open the Computer / This PC window and right-click the iPhone icon. Select "Import pictures and videos" to start importing pictures. Click "More options" and check the box "Delete files from your device after importing." Follow the onscreen instructions to import photos to your computer and then delete them from your iPhone.
   • For Mac - Connect iPhone to Mac via a USB cable. Open "Image Capture" and select iPhone from the list of devices in the menu on the left. Expand additional options at the bottom of the menu and select "Delete after Import". Click the "Import all" button to import the photos to your computer and then delete them from your iPhone.

5. 

   Turn off some effects. Some menu transitions on iOS can slow down older iPhone models. Turn off these effects to improve performance:
   • Open the Settings app and select "General".
   • Click on "Accessibility".
   • Click "Reduce Motion" and turn on "Reduce Motion".
   • Go back to the "Accessibility" menu and select "Increase Contrast". Then, turn on the "Reduce Transparency" option.

6. 

   Delete music that you no longer listen to. Like pictures, music files may take up a lot of memory on your device. If your phone runs low on memory, deleting songs that you no longer listen to may improve device performance. With music purchased on iTunes, you will be able to re-download it at any time. With music synced from your computer, you can restore it by resyncing.
   • Open the Settings app and select "General".
   • Tap "Storage & iCloud Usage", then select "Manage Storage" in the Storage section.
   • Tap Music from the list of apps.
   • Swipe any specific artist or song from right to left then press "Delete". You can also click "All Songs" to delete all music at once.

7. 

   Use a RAM usage check app. iPhone doesn't have any built-in apps to check how much RAM is in use. This is because the system implicitly handles the RAM distribution and is not visible to the user. If you want to monitor your RAM usage, you need to install additional support apps.
   • One of the most popular apps is System Status, but you won't be able to see each application's RAM usage.

Advice

• For Android and iPhone, you don't have to close all apps in the recent usage list. The system will pause these applications when you are not in use, thereby limiting the consumption of system resources.
