There are a few steps that can be taken to help minimise memory usage:

1. Close any unnecessary applications or programs that you’re not currently using.
2. Regularly remove any unused files or applications from your device.
3. Clear the cache memory of all applications, especially those you visit frequently.
4. Increase your device’s virtual memory and review the size of the active page file.
5. Check that your device has sufficient physical memory and is running the latest available operating system.
