Samsung Galaxy S5 or QHD display with FullHD, what is the most efficient screen?

Since the G3 was launched LG has put into question the advantages of the high resolution of the screen. First the question of whether it is necessary to raise the definition images up to 2,560 x 1,440 pixels proposes QHD display. The second point of contention is the energy consumption, which has proved to be greater than any screen FullHD. However, is it the same in the case of Samsung Galaxy S5 LTE-A?
Different tests have determined that the QHD screen LG autonomy remains G3 model. That is, the 2560 x 1440 pixels of such panels shortens the battery life. Given this technological lock AnandTech team wanted to see if the same thing happens with the Samsung Galaxy S5(cheap cell phone cases) LTE-A, a model that also includes a qHD panel. In this case it is easier to compare the result with respect to other alternatives FullHD screens since the manufacturer's catalog within the international version of the Samsung Galaxy S5, that its technical characteristics contains a FullHD screen is included.
QHD vs FullHD
The various tests performed on both models are conclusive: the energy consumption of the version with QHD screen is displayed even when experienced by the Samsung Galaxy S5 with FullHD display. As the graphs show, autonomy has barely changed in tasks such as web browsing, along with WiFi connection or 4G connection.

 

Not all the weight rests on the screen
However, the reading of these data does not allow us to ensure that the energy cost of the QHD screen is the same as that of the FullHD screen. If you are the energy needs of the overall smartphone, details of which we can draw some conclusions. The most important is that the Qualcomm Snapdragon Adreno 805 GPU and 420 processor(samsung galaxy s4 cases) show that more efficient Snapdragon chip 801 Adreno GPU and its respective 330 The same applies to the LTE modem and controller wireless WiFi. Therefore, the increased energy efficiency of other components seems to compensate for the addition of QHD display.
SuperAMOLED, the key
In any case, the disparate results between S5 Samsung Galaxy LTE LG-A and G3 have an explanation. And the SuperAMOLED display based on OLED panels would be better prepared than the energy-backlit panel LG model.
