In Samsung Galaxy S6 the company Samsung implemented a battery with a slightly lower autonomy than the one available in the old model of the terminal, so now we see a comparison between the official specifications regarding battery, they being compared with iPhone 6 si 6 iPhone Plus. In the image above you see the official battery life specifications for all three terminals, so we are not talking about real-world usage tests for any of the three devices, so we cannot get a clear idea of their performance.
If in the case of the iPhone 6 Plus the official specifications regarding the battery life turn out to be real, in the case of the iPhone 6 they are far from reality, so it remains to be seen how they will be in the case Samsung Galaxy S6. If Samsung Galaxy S6 battery life will be identical to that of the Samsung Galaxy S5, as those from Samsung say, then the new terminal will not have a better autonomy than the iPhone 6 Plus. Even so, it will be better than that of the iPhone 6, so all those who will not buy this device will have a long use experience.
