Battery & Charger

Knowing the performance of the Exynos 7885 and the magic of AMOLED displays, the Galaxy A7 (2018) is looking pretty good in terms of battery life even though it has a 3,300mAh battery only.

In our usual PCMark battery life test, the Galaxy A7 (2018) can actually last quite a long time – just as efficient as the Snapdragon 636 chipset.

Charger

In the world of smartphones these days, we’re presented with 5V 2A chargers as a standard. However, the Galaxy A7 (2018) comes with a 5V 1.55A charger instead. It’s… definitely slower than the commonly-found chargers that we have.

But objectively, how does the 5V 1.55A charger competes? Take a look at the graph below.

Surprisingly, it doesn’t seem to matter if we’re using the included 5V 1.55A or a 5V 2A charger. From the looks of it, the charging speed is limited by the phone itself.

Both chargers will take about 43 minutes to reach 50% of battery charged, and a total of 77 minutes to reach 75% of battery charged. Obviously, it’s not fast.
