Samsung Galaxy A8 battery life test results


The Galaxy A8 is the newest addition to Samsung's A series of thin, light and good-looking affordable Android phones. The largest one in the series, the Galaxy A8 features a 5.7" display, all in a body measuring just 5.9mm thick, with a sleek metallic profile.

Its slim size dictates a smaller than average battery pack, and the Galaxy A8 features a 3050mAh cell. Hidden behind the non-removable back cover, you can't easily swap the battery, so it's even more important for the phone to do well in terms of battery longevity.

Official Galaxy A8 battery stand-by time stands at the below average 12.7 days (304 hours), but in order to fully understand the capabilities of its battery, we had to test it ourselves. Our custom battery test is performed with the display calibrated at 200 nits (keep in mind that for AMOLED screens brightness changes depending on the content, the 200 nit value applies to measurements of an all-white background). Then, we run a custom script specifically made to simulate typical smartphone use and loads.

So how does the Galaxy A8 battery does in our test? Not too bad at all: with a score of 8 hours and 49 minutes (this is the time the phone lasts with the script running non-stop, with the screen always on), the A8 does better than the majority of its rivals, but still fails to reach the very best battery performers.

In real life, our impressions are that the phone will easily last a full day even under heavier use. It typically takes us around a day and a half until we need to recharge the phone. The Ultra Power Saving Mode that we know from early 2014 is also on board, so you can switch it on and have a crippled smartphone experience with a black-and-white, but also one that will last you for hours on single digit battery percentage and allow you to take and make a call when you need that.

Finally, when it comes to recharging, the Galaxy A8 lacks quick charging and it takes a whopping two hours and 24 minutes for it to fully recharge from 0 to 100%. Take a look at how these numbers compare to its rivals right below.
