  • The Galaxy S7 fetches inferior battery life than the S6 despite much larger cell

The Galaxy S7 fetches inferior battery life than the S6 despite much larger cell

The Galaxy S7 fetches inferior battery life than the S6 despite much larger cell

With the 2016 generation of its Galaxy A line, Samsung notched something of a record, with both the A5 and A7 managing nearly 10 hours before dying during our strenuous, custom battery life test. Given how the Galaxy S7 features a significantly improved cell capacity of 3,000 mAh (compared to 2,550 for the S6), we were hoping that Samsung has a winner on its hands. Alas, that doesn't seem to be the case.

The Galaxy S7 clocked 6 hours and 37 minutes, a disappointment compared to its predecessor

We've had the Galaxy S7 in our possession for a week now, and as you can imagine we've been hard at work on the review. A major part of it, battery life is something we all care very much about, and that's where our custom battery test comes in. After forcing the S7 through it, we are unfortunately left with the confusing achievement of 6 hours and 37 minutes—a disappointment given the 7 hours and 14 minutes its forerunner clocked. Considering the larger cell of the Galaxy S7, it's a bit weird to see such a notable delta.

A few things are worth pointing out when viewing the results. First off, the Galaxy S7 unit we've got sitting on our desk is the Verizon-branded, Qualcomm Snapdragon 820 variant, and not the Exynos flavor. Second, to ensure uniformity across tested devices, we always set brightness to 200 nits and loop a pre-made script that is designed to replicate the power consumption of typical  real-life usage.

As for when the Galaxy S7 is full out, we clocked a very decent result: 88 minutes to get topped off. Going back to that larger cell, it's only logical that the S7 will need a bit longer than its predecessor to go from zero and back to full again. It's still a leading score.

To be fair, we were actually looking forward to testing the Galaxy S7 for resilience. It seemed pretty much a given that it would best its predecessor, and we even dared hope for a significant improvement. As it is, the Galaxy S7—at least the Snapdragon 820 variant—is starting to lag behind other recently released devices, such as the iPhone 6s and even the Xperia Z5. See how it stacks up for yourself:

GSMArena is definitely the best phone site, and they pass every phone through different lab tests before releasing any review.

It's because they did not turn on the always on display off, that and the sd 820, on a small note Briefing as been removed from the uk Samsung s7 sim free phone, there is no lag at all and you get Samsung new news app on the left screen, you also got 131594 in antutu and the rom install is only 7gb in size

Why come back to the site that never post any trusted battery life test? Go back to your favorite site (GSMarena) that always give the result that you wanted to see.

Did I reply to your post? NOPE. Or is it this " kkmkk" your second account here on PA? Why bother explaining to me what do you mean by your previous comment when I didn't even bother to reply to your first comment in the first place. And stop saying that you are going to leave PA. People who said stuff like that are the kind of people who always come back even if the site terminate their account. And even if you leave this site will do fine without you.

Have a nice day. Good Bye.

Look's like Qualcomm are continuing to make their hardware power hungry.

Could be the deciding factor this year, lets hope it's not true as we don't need another year od phones with crappy battery life.

Going to wait on all different sites and their testing methods to average it. Seems Samsung might have upped the amount of crap running in the background as well as packaged facebook/messenger along with the device for that added kick to the nuts.

Interesting find. I have the (T-Mobile) S7 myself and have owned the S6 for about 8 months before that. The S7 blows my S6 battery out of the water and they have the same applications installed. We are talking hours and hours of difference. My S6 would have around 30% battery around 3 in the afternoon and my S7 will end the day with about 50% battery.

21. tokuzumi (Posts: 963; Member since: 27 Aug 2009)


Still early to be doing these tests, in my opinion. The S6 had a few bugs in the beginning which updates were quickly sent out to address. This same test should be done in 2-3 months, after everything settles down, to see what the real story is.

Probably they got something that is running on S7 they aren't aware that isn't on S6.
My Galaxy S5 even beats S6 anytime when i use recently purchased new battery from Samsung (not a cheep copy from amazon resellers)

PAA should question their tests vs other sites. If Amandtech is getting 9 hours from the S7 Edge and just over 8 from the regular S7, then how is PA only getting just over 7hours.

DO THE MATH PA! It would be very improbable for a larger cell to get nearly identical amount of usage time based on your tests.

Whatever script you are using, its a piece if crap obviously.

a battery that is more than 25% larger, isnt going to just be minutes past the older model. It would last at least nearly an 1:30+.

29. milos (Posts: 59; Member since: 29 Oct 2012)


Even if their tests aren't perfect, Im still disappointed!

S7 series have better more power efficient processor, same size and resolution ( but possibly newer more power efficient screen than s6, and newer firmware. All that with that much bigger battery should improve the ON time significantly. At least 20-30%

So where does the power leak out to now that did not in a previous model?? Something is abusing it more! Maybe a demo model has some bs script running in background.

It uses the same screen. So all efficiency depends on the new CPU and GPU.

Samsung better realise that the Edge Screens might make the phone look better,but its the Edge Applications that is causing the battery to drain to quick,Edge screen phones would sell a lot better if Samsung offered the removable battery option,o.k you can disable the Edge applications,will be sticking with the Galaxy s6 Edge plus that offers much bettery batterylife

Dont trust these iPAaggot battery results. Just check the most trusted knowledgeable sites on the net.

From anandtech battery tests :

S7 Edge gave 1 hour more than iPhone 6s plus. S7 did the same compared to S6

Techradar on S7 battery :
Galaxy S7 comfortably beat the iPhone 6S, Sony Xperia Z5 and HTC One M9.

*** From Techradar S7 battery test :

"I ran the techradar 90-minute full HD video test on the Galaxy S7, with screen brightness on full and the handset connected to Wi-Fi, with accounts syncing in the background. Starting at 100%, the Exynos 8890-powered S7 dropped just 13% during the video. That left it with 87% in the tank, which is a very impressive result. Meanwhile our US variant, running the Snapdragon 820 chip, lost 16% in the same test.

Both comfortably beat the iPhone 6S (which lost 30%), Sony Xperia Z5 (25%) and HTC One M9 (31%)."
