The Android system will take care and prioritize which apps need to be stored in the virtual memory and which shouldn't be. Virtual RAM handles all the apps which do not have any dynamic functions in the background and will keep those kinds of apps in the memory for a longer period of time. This is where the Virtual RAM comes in handy. Consider you have 10 apps open on your Android smartphone and there is no more space in the actual RAM of the phone, so what actually happens in Android closes the apps which are not running in the background or performing any dynamic tasks in the background 一 or the system just kills the app that has the lowest priority and whichever is the oldest app among the ten apps. To understand the concept of how Virtual RAM works, let’s take an example here. First things, first, if you extend RAM, you won’t see a bump in the amount of RAM used by the system 一 while the storage is allocated to Virtual RAM, your physical RAM will be of the same capacity. Now, let’s see how this feature actually works in real life. For instance, the 6GB configuration of the Realme Narzo 30 5G supports an extension of 5GB, taking the total up to 11GB. When you toggle the virtual memory feature on your smartphone, the phone actually allocates the amount of memory you’ve selected as virtual, but to allocate the space in the internal storage, you will have to restart the phone. The amount of RAM you can extend depends on the device and for now, we’ve seen from 1GB to up to 7GB of extended RAM. While we had to get root access a few years back to extend and get additional Virtual RAM, it's now much more simple 一 just a toggle and you’re getting more RAM. How does it work?įor those who are familiar with Linux, this feature is pretty commonly used and it's actually borrowed from the PC world to smartphones. As the name suggests, this is a “virtual” RAM which means the amount of extended RAM isn’t physically present as RAM on your smartphone.įor instance, if a phone has 6GB RAM and 128GB storage and you extend RAM by 5GB, technically, you will now have 11GB of RAM and about 123 GB of internal storage. In simple terms, Virtual RAM is a feature where a portion of your phone’s internal storage will be used as additional RAM which effectively increases the total amount of RAM on your smartphone.
