Back in July I decided to swap my phone and tablet’s runtime from Dalvik to the (apparently) newer and faster ART runtime. The difference between the two being that Dalvik performs Just-In-Time-Compiling (JIT) of the applications you are running, whilst ART performs compilation during the installation, saving the need for it later.

I had read that ART will use more space (storing precompiled executables) and the performance boost from using the precompiled executables would be noticable and a battery saver. Instead applications were choppier. I realised this even more strongly when I reverted back to Dalvik.

I appreciate that ART is still meant to be in Beta and a preview for developers, but I’m still disappointed it doesn’t work even remotely like people would hope. Yet.
