Which phones had the best battery life in 2017? And does battery life on phones ever improve or does it stay roughly the same throughout the years?
At PhoneArena, we do a standardized proprietary battery test on all phones that we review. We test every device diligently: we make sure that its screen is set at the same brightness level and to ensure this we measure brightness level down to the nit with a special colorimeter, we also turn off external notifications and other sources of power drain that might skew the results of our test. For some phones, we double-test if we have doubts about the results. This gives us a comprehensive picture of battery life numbers for all major flagships not just in 2017, but also through the wider lens of time.
As 2017 winds down to a close, we take a look at all the major flagship phones of the year and their battery life performance, and we compare the results to the average battery life of flagships in 2016 and 2015 to see if there is any improvement.
But first, let’s look at the list of 2017 flagship phones to see which one scored best in terms of battery life.
