Here’s how to expand the RAM of your smartphone for free

Manufacturers are diligently increasing the amount of RAM and storage memory in new smartphones. In 2021, for the normal functioning of the operating system, at least 6 gigabytes of RAM is required, and in order to install many applications and store personal information, the amount of storage memory must be 128 or 256 GB. Xiaomi, Oppo, Vivo, OnePlus, Samsung, Realme and other companies have recently added a useful feature to their firmware such as expanding RAM. What it is and what it is useful for? and How to enable it?


RAM expansion or Memory Extension is a special feature that expands the amount of RAM from the storage memory, that is, internal storage. If the internal storage has a lot of free space, you can move it to the RAM.

It works like this: for example, the internal storage is 256 GB and the built-in RAM is 6 GB. You take from the internal storage 3 GB and transfer them to RAM. As a result, the RAM will expand to 9 gigabytes. This 3 GB will be reserved for the RAM and will be gone from the internal storage.

Memory Extension allows you to increase the RAM, mainly by 3 GB. For some devices, expansion is only possible by 1-2 GB. The rules are as follows:

1. Phones with more than 128 GB of ROM – 3 GB RAM expansion.
2. Phones with 128 GB ROM – 2 GB RAM expansion.
3. Phones with 64 GB ROM – 1 GB RAM expansion.

Note! Some phones can even expand up to 5-7 GB. Such an opportunity is available on flagship devices with 256 GB and above, but not on all – the information must be specified separately for a specific smartphone. One fact remains the same: the larger the storage memory size, the more gigabytes you can add to the RAM. You cannot borrow gigabytes from a memory card, since the external storage is much slower than the internal storage.
