Apart from full forms i.e. RAM is Random Access Memory and ROM is Read-Only Memory, is that RAM cannot hold data without power but ROM can. And, throughout this guide, our principal topic will be RAM and not physical storage which in a computer language is well known as ROM.

Most users look for a better processor in Android devices and they don’t give much attention to RAM. The thing is that RAM is one of the most essential features of a device and even if the processor is top-notch and you don’t have enough RAM, then having that processor is almost useless. RAM is the memory that lets you run apps on your device.

The greater the RAM,  the more apps you can run simultaneously and the less lag you get while using these apps. Budget Android devices don’t have enough RAM to run high-performance apps but you can easily increase RAM in Android phone devices by following one of the methods below.

However, there are applications that allow smartphone/tablet users to expand their device’s RAM by a substantial amount. Take the Roehsoft RAM Expander for instance. We had used this app in one of my devices, which has only 256 MB RAM and could not run even some basic games. But after using the app, there was a noticeable change in the device’s performance.



The most beautiful part of this app is a small, configurable widget that places on top of any app and one-click to RAM boost.

RAM Booster comes with auto-boost in 4 levels: aggressive, strong, medium, gentle.


☆ Aggressive: kill most of the low priority apps
☆ Strong: Kill apps that is low priority as well as consume lightly below an “average”
☆ Medium: kill apps that consumes memory above an “average”
☆ Gentle: kill only apps that use considerable memory

Most of the Android devices bundle with limited memory. Android task manager will selectively kill low priority tasks in order to reserve memory to a higher priority task. That’s not always run at an appropriate time, causing low responsive apps, lagging,
especially when you launch a new app after heavily browsing web pages. It causes a worse experience.

There are 5 ways to boost
☆ Auto-boost: boost automatically under RAM available & timing conditions
☆ Overlay widget – Enable RAM Booster overlay widget (on by default), adjust widget’s position, and tap on widget to boost anytime you want
☆ Home screen widget – one tap to boost (long-press your home screen>Widget to add RAM Booster widget)
☆ Notification bar – one tap to boost (toggle notification bar visibility in app’s setting)
☆ Boost Now – tap this button from app’s main screen


X BOOSTER: (no root)

Boost your speed, battery life and stability with preset modes for root users.


There are many apps that save battery or increase performance, however Root Booster uses the most proven settings to achieve the best results. You can easily apply these settings with preset modes which ensure speed boost, battery boost or stability boost. These modes are achieved by applying appropriate settings to the main phone components. Here are some explanations for what particularly Root Booster does to your CPU, RAM and Android OS system.

RAM (memory manager)
The main reason to change the VM heap size is stability improvement. Many big applications need a big amount of memory (VM heap) for their work. If the VM heap size is smaller than the requested memory, it causes an application crash (Out of memory error). Setting heap size is hard task and there is no manual to set up for better performance. Better performance can be only achieved by testing.
