Understanding battery consumption in the Galaxy S8

Since the launch of the Galaxy S6,Samsung has provided a power and memory consumption control tool to the system. Over time, this service has evolved and, with the launch of the Galaxy S8, the South Korean manufacturer has consolidated such a tool as a great option in an attempt to save the energy of its smartphones.

Called “Device Maintenance”, this system function offers different performance modes both the Galaxy S8 and the Plus variant, as well as two modes of power consumption.

Performance Mode

The “Performance Mode” feature is part of the operating system and is integrated via  Device Maintenance in the Galaxy S8 settings. This feature was implemented to the system with the launch of the Galaxy S7 line and, with the launch of Galaxy Note 7,brought new features such as screen resolution control that subsequently reached the Galaxy S7 and S7 Edge with the update of the operating system to Android Nougat.

With the problems with the battery explosion in Note 7 in 2016, I view Performance Mode as an important feature on Samsung devices, as it offers four different types of power consumption based on hardware configuration, Engineers’ chance to optimize the design of the device to the point of bringing a super-designed smartphone to market without having to limit battery capacity too much.

In fact, the Galaxy S8 has 3.000mAh of battery, while the Galaxy S8 + has 3,500mAh. With screens of 5.8 and 6.2 inches respectively, the two handsets needed a smart solution to deliver good power autonomy.

There are four performance modes for the Galaxy S8 and S8 +, see below:

  • Optimized(recommended)-This is the way the Galaxy S8 leaves the factory. It takes stock of the battery life and screen resolution for everyday use. It can be used with up to three screen resolutions: HD +(1480×720), FullHD +(2220×1080), WQHD +(2960×1440). The energy savings will be directly related to screen resolution;
  • Game-Improves the gaming experience by making games run more efficiently. It can also be used in all three resolutions in optimized mode, but by default it is FHD +.
  • Entertainment-Sets up music and videos for high quality sound(UHQ), enhances images for maximum quality through video enhancement. It can be used in all three resolution settings, but by default it uses WQHD +;
  • High performance-Utilizes the full potential of the Galaxy S8 display, maximum brightness and resolution.

As you may have guessed, each of these modes offers a different experience with the device. So, during the time that using the Galaxy S8, I can say that the battery life of the device varies according to the use I make of the system resources. So either I have to charge the device at least once, every day, or every other day and no. And this is also proven through benchmark testing.

Galaxy S8 battery performance benchmark

For this type of test, our team uses the PCMark 2.0 battery benchmark.This application measures the performance and battery life together. And these tests are based on day-to-day use of the device instead of a random algorithm.

At the end, the result of the test is offered in a table, in which we can see the energy consumption at each moment of the test, as well as the temperature variation during the process.
