The Grand Duos was a hugely popular device and is now more than three years old. Obviously enough, it’s more than naive and foolish to expect an official Marshmallow update for Grand Duos. But, because it runs Android, and more importantly, enjoys developer support, there are some great unofficial Marshmallow update available for the Grand Duos thanks to custom ROMs like CM13.

Though, with 1GB RAM chip inside, the Grand Duos isn’t best spec’ed to run Android 6.0 Marshmallow update. But it should do well. Firstly, the minimum requirement for Marshmallow is 1GB, unchanged since Google announced the same for Lollipop.

With the Marshmallow update for Grand Duos, you will get its famous features like Doze mode, app control and app permissions management, Now On Tap, etc.

You can also expect battery life of Grand Duos to increase by around 20 percent on Marshmallow update. On Android 6.0 Marshmallow update, your installed but little/rarely used apps are hibernated completely by the system to save battery use from such apps, and that also frees up memory as these apps don’t run any background activity at all.

So next time you install a wallpaper app on your Grand Duos running Marshmallow update that you long forgot to use, it won’t be draining your device’s battery. Feel free to install more apps than usual on Marshmallow.

Moreover, when the device is not in use, the system blocks access to mobile data and background functions to all apps except for the most basic ones. Remaining apps are provided access to data and normal functions in little gaps so that you don’t miss out on important notificaitons. Once the device comes into use — system gets to know it by detecting device movement — all apps get access to data and background operations instantly.
