The Galaxy S7 edge stalls, delivers middling battery longevity

The Galaxy S7 edge stalls, delivers middling battery longevity

Battery life being the tough nut to crack it is, we—and pretty much everyone interested in Samsung products—were pretty excited to hear that the South Koreans weren't joking around, and implemented a giant, 3,600 mAh battery with the Galaxy S7 edge. Truth be told, apart from the camera, resilience was the other metric we were most excited to get some actionable information on. Seeing as how the S7 edge has been in our trusty hands this past week, we obviously did just that.

The Galaxy S7 edge was done in just 7 hours and 18 minutes—much sooner than we were hoping

Unfortunately, we bring no good news. The Galaxy S7 edge passed through our demanding battery life test and came out just 7 hours and 18 minutes later—sooner than we expected, and much sooner than we dared hope. In comparison, the Galaxy S6 edge+, which is the de-factor predecessor of the S7 edge, lodged the impressive 9 hours and 29 minutes, all with "just" a 3,000 mAh cell.

Given this underwhelming result, it's worth pointing out that the Galaxy S7 edge we've got over here is the Qualcomm Snapdragon 820 flavor, and not the Exynos make. It's possible that Samsung's own silicon will deliver better performance, though we're not exactly holding our breath—if it does, however, it'd be interesting to figure out Samsung's motives for going with the 820 in the first place.

For what it's worth, the Galaxy S7 edge was tested under the same conditions as any other device going through our custom test, which hasn't changed for a while now. So brightness set to 200 nits and a looping script that is designed to replicate the power consumption of typical real-life usage.

Switching gears to recharge times, the S7 edge redeems itself with a very good showing: just 99 minutes to go from zero to full. Given the large cell at play here, that's a pretty decent result, and still among the best in the industry.

The most disappointing thing in this great phone so far... I hope the Exynos version does better

I hope too. I just receive my S7 Edge wirh Exynos 8890 inside. Looking for the results of SD820, battery speaking, I'm very disappointed about it. Did I rush for preordering? I still hope "not".

Did it confuse you? It's a picture from a famous monastery in Romania with preast skuls which rules that place. Did I change it?

i don't believe PA's conclusion here. even if true, there will be some software fixes for both devices coming soon i'm sure.

I'm getting about 8.25 hours of SOT with my S7E, on average. Brightness about 50%.

If Sammy wants to improve battery life...they just nees to get rid of one of the worst design changes in a mobile OS. And that would be the white backgrounds of Lolipop & Marshmallow. The need to go back to more of a black theme, like was the case with their KitKat ROMs. I know it was a Google design change...but white on an AMOLED screen is by far the worst choice ever, for the base color of your OS and setting, app drawer etc.

I slapped on Nova 3.3 so I could have a black app drawer again.

Can't stand the white and pastel thing.

I don't believe a word. It makes nosense. Galaxy s6 edge has 50mah more of battery than s6, and in your 'tests' battery life is ONE HOUR longer. Given that, I do not trust your tests anymore. Let's wait for gsmarena, which is an imparcial and reliable source.

Don't jump to conclusions. There are still other techsites and if others say that s7's batteries last longer than what pa's writing, then these whole s7 battery issue articles will be forgotten.
