Using an Android phone is no east feat, I tell you. Apart from the fact that if you’re a fond of playing around with the intricate workings of your operating system, and consequently flash a new ROM every week (can be even day, in extreme cases), one major annoyance that you’ll feel is the battery, which essentially drains faster than any other smartphone OS that I’ve played around with. It’s not really necessarily the device’s fault – a simple code inspection actually establishes that it’s how the AOSP is built which causes the battery to drain faster, and perhaps it’s Google’s acknowledgement of this fact that they’ve decided to take up Project Roadrunner after the successful implementation of Project Butter with Jelly Bean.
