3.Uses big.LITTLE technology
?

Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking e-mail will use the less powerful cores to maximize battery life.
