Rumor tentang Android 4.2 sudah mulai menyebar. Android and Me, salah satu fansite Android termasuk yang pertama yang mengabarkannya:

New Project Roadrunner

Rumor: There is major effort to improve the battery life called Project Roadrunner.

Speculation: Details are pretty light on this one, but it sounds like Project Roadrunner will enhance battery life the same way that Project Butter enhanced the overall responsiveness in Android 4.1.

First Project Butter and then Project Roadrunner, playing catch up?
