On an iPhone (or any other current iOS device) you can know that you have nearly all, if not all of the processing power available (OS does notifications, wifi, etc). On an Android you have no idea how fast the processor is, no idea how much there is going on in the background and so on. You will have to aim lower for the game to be usable on an average Android, while an average amount of other applications are running. Possibly not on topic, but true and relevant.
