QCM+: Ultimate Battery Saver For Multi-Core Android Devices (ROOTED)

QCM+, also known as Quad Core Manager Plus, is an advanced battery saving application developed by seaskyways, an aspiring developer from XDA Developers. This app requires root permissions to work. In simple terms, QCM+ gives you a complete control of the cores in your multi-core smartphone. You can turn off/on cores manually or when the display is turned off, thus helping to save a lot of battery. This app is working on almost all multi-core devices excluding some models of LG and Samsung.

How does QCM+ work?

QCM+ allows you to turn off the remaining cores in your device except the first core. So, if you have a dual-core smartphone, then you can turn off the second core when your smartphone is not in use. Same implies to quad-core users, in which they can switch off three cores leaving the first core.

Notable features of QCM+:

Manual Cores Control : This app provides a simple and user friendly interface, mostly buttons and text, allowing you to turn off a core at the press of a button, and another button press to turn it on again. QCM+ checks your cores’ statuses asynchronously to keep you in sync with your cores’ current statuses.

Full Control On Cores: Also known as Persistent Mode. This will restrict the system and anybody else from changing the cores’ statuses except the app itself, which will give you full control over your cores.

Automatic Cores On/Off: Abbreviated as ACOO, this feature will turn off your cores when you turn off the screen (or the phone is idle) and then automatically turn them on when you turn the screen on. More than that, it adds the ability to customize which cores you want to turn off and on, and it adds the option to have two advanced and alternative modes for turning on/off your cores. This features saves a lot of battery.

Note: This app is available in the trial version until July 30 and then an additional 15 days (after this trail period) will be allotted for ACOO feature. Once that trail expires, users should pay a donation to continue usage of the ACOO feature.

    Hello Ahmed

    It should work on your device. But by this app, you can save battery by disabling cores. So this app is not for improving performance but you can enjoy more juice…..
