Hidden deep in Android, following the KitKat 4.4 release, is a feature that can be enabled to instantly speed up your Samsung Galaxy S5, HTC One M8, LG G3, and pretty much any Android device that supports KitKat.
It’s called ART, and that stands for Android Runtime, which is the successor to the Dalvik system currently used since Android’s inception. ART uses what Google calls an ‘ahead of time’ compiler as opposed to Dalvik’s ‘just in time’. Dalvik worked by converting each app on the fly when it was called upon to be launched. ART on the other hand converts it during installation, ultimately resulting in a larger app file size, but meaning the app launches pretty much instantly. The result? The device is quicker and battery life is improved.
So how do you do it?
The new ART runtime system isn’t enabled by default in Android 4.4 KitKat so you’ll need to head into the hidden ‘Developer Options’ menu in the Settings to access it. To enable the hidden ‘Developer Options’ go into Settings > About Phone > Build number and Tap the build number 7 times. Once there, go to ‘Select Runtime’ and change the selection from ‘Dalvik’ to ‘ART’.
You’ll have to reboot after changing the setting and you may have to wait a few minutes whilst ART does its thing in the background converting all your installed apps, but once the progress meter is done you’re good to go.
Whilst ART provides increased speed and improved battery life, you may find that not all Apps are 100% compatible; however since Android L has been released with the developer preview, the chances of finding an incompatible App has greatly reduced.
