Best in class? Samsung Galaxy A7 (2017) scores amazing on our battery life test
A weekend away from the charger? Get the new Galaxy A-series."The marriage of a largish battery and a 1080p or HD display seem to be the winning combinations for battery endurance these days, as the Quad HD flagships are all clustered in the 6-9 hours range of screen-on time in our proprietary script. Samsung, however, being both the producer and the assembler of the screens, chipsets and memory of the new A-series, has managed to optimize them better in terms of power consumption than other brands that don't make everything in-house. Take the Honor 8, for instance - while it still scores nine admirable hours of screen-on time in our test, and has a homebrew Kirin 950 chipset built on a modern 16nm mode, plus a 5.2" 1080p display, just like the A5 (2017), it lasts 20% less than Samsung's midranger with the same size battery pack.
