Samsung Galaxy S6 Edge: focus on power and autonomy

Now that the screen of the Samsung Galaxy S6 Edge has no more secrets for you, the time has come to move on to the rest of the program and take a look at its computing power and its autonomy.

If you arrive freshly, then know that this article is the third in a series dedicated to the latest flagship of Samsung. It follows my grip and focus devoted to the terminal screen. The next focus will focus on its photo sensor and its overlay.

Then, a complete test using the elements of the previous articles will be published. In the meantime, if you have any questions and would like me to expand on some points, just leave a comment following this article.

A little technique to start

I'm not going to list you all the features of the Galaxy S6 Edge once again, but we still need to take a quick look at the processor and the battery in order to tune our violins.

The Galaxy S6 Edge's CPU is engraved in 14 nm and this is a real technical feat. This detail is far from trivial because it also means that the electrons circulate faster. In addition, the chip also consumes less power.

It is made up of eight cores, based on a big.LITTLE type architecture. There are therefore four A53s clocked at 1.5 GHz for common tasks and four A57s clocked at 2.1 GHz for the most demanding tasks. The transition from the first cluster to the second is completely transparent for the user.

In addition, there is also a Mali-T760 MP8 GPU, an improved version of the GPU integrated in the Note 4. It is clocked at 700 MHz and it supports OpenGL ES 3.1 / 3.0 / 2.0, OpenCL 1.1 and Direct 3D 11.1. Difficult to do more complete, right? Certainly, and we must also count on 3 GB of RAM.

The battery, for its part, offers a capacity of 2,600 mAh. It is compatible with wireless charging (Qi) and you just have to put the terminal on its base – or on any compatible base – to recharge it.

Not bad, but there is better because it also has the right to fast charging. It will therefore suffice to plug in the phone for 10 minutes to have 4 hours of battery life.

We will see a little later that this detail is far from trivial.

A true monster of power

Determining the computing power of a phone is not easy. The easiest, ultimately, is to rely on specific tools.

I chose a few, like AnTuTu, Quadrant or GeekBench. I took to clean the phone's RAM each time before launching them, and to close all running applications.

These results are obviously given as an indication and they will especially allow you to compare the performance of the S6 Edge to your own terminal:

  • AnTuTu: 58,239 points.
  • Quadrant: 6,210 points.
  • GeekBench: 1,499 points in single-core, 5,128 points in multi-core.

Note that I performed several tests each time, to then calculate an average. If you don't get exactly the same score, that's perfectly normal.

The Galaxy S6 Edge is clearly the most powerful device that has passed through my hands lately. Its chip is extremely fast and it would even perform better than the Snapdragon 810 if I believe the research I have done.

And in practice then? There is nothing to say. The terminal is extremely responsive. I had noticed some latency on multitasking at the beginning but the two patches deployed by Samsung last week ( here and there ) seem to have fixed the problem.

I play very little for lack of time. However, I still made the effort to install a few games on the S6 Edge just to see what is in the gut. No latency on Gun Bros 2 , Godus , Hearthstone (huhu) or even Galaxy on Fire 2 HD . The opposite would have been surprising anyway.

Improved autonomy

As indicated above, Samsung has chosen finesse, and the Galaxy S6 Edge must be content with a battery with a capacity of 2,600 mAh. In addition, the manufacturer has made numerous modifications to its overlay to reduce the energy consumed by it as much as possible.

My first tests were not very conclusive since the terminal hardly managed to exceed a day with a single charge, for conventional use.

I managed to save a few hours by finely adjusting the screen brightness and disabling services that I didn't need, but it was not until the deployment of the new version of Samsung's push service to improve the situation.

At the moment, being careful and for normal use, my Galaxy S6 Edge manages to last a day and a half. It falls to one day for a little more sustained use (games, music, videos). It's not perfect yet, but there is something better and Samsung has been pretty quick to respond.

Whatever happens, it will also be necessary to rely on a simple energy saver capable of reducing the frequency of the processor or the brightness of the screen to save a few hours, and on an ultra mode which will load a simplified version of the platform.

In this case, we will be entitled to a magnificent interface all dressed in gray, and an extended autonomy of several days.

I will stop there for now. I leave you with my video.
