触摸视图时Android FPS会增加，而未触摸时FPS会降低

Question

I know this is a really odd problem. But has happened both on my Nexus S and Galaxy Tab.

When i drag on the view FPS increases to MAX FPS however if I don't it'll start fluctuating from 45-60. I've already tried tested simulations and it isn't the batching. I am using Open GL and there are no memory leaks. Any ideas?

This happens on all projects.

Are you using Jelly Bean? They added a new feature, as part of Project Butter, that might explain this.

Jelly Bean has more reactive and uniform touch responses, and makes your device even more responsive by boosting your device's CPU instantly when you touch the screen, and turns it down when you don't need it to improve battery life.
