Asus Zenfone variants show Performance vs. Battery Life

With over a dozen variants of the Asus Zenfone, we looked over most of them and measured their battery life and compared it to their performance as measured by our standard benchmarks.

Just as we suspected, the chart below shows a correlation between the two.

The general trend is that the higher the performance of the handset, the lower is the expected battery life.

The inverse correlation is evident with the Zenfone 2 Laser which topped the battery life ranking at 12 hours, 31 minutes. It has the same 3,000mAh battery as most other Zenfones but since it is only running a Snapdragon 410, optimal battery consumption is achieved.

The Snapdragon 615 fared well too. On the contrary, the ones running the fastest Intel Z3580 processors are the ones that eat up a lot of juice.
