Regarding the battery, the reduction of this began to decrease progressively as the temperature increasesince both devices began a loss of autonomy that could be considered similar, but when the iPhone X reached higher temperatures, the degradation of the battery settled, while the autonomy of the iPhone 14 Pro maintained a more constant reduction, more continuous in the time.
I then stopped the series from playing and let both drives cool down. This is where I found interesting data, since, the iPhone X It continued to lose autonomy, while the iPhone 14 Pro once it returned to “normal” levels, its autonomy was not reduced.
Many users may think that it is normal, since the difference between the two units is abysmal, above all, because in five years, technology has advanced a lot and, it is logical, that the iPhone 14 Pro maintained its autonomy better than the iPhone X, but, the ultimate test is when I performed the same test with the iPhone X iOS 16.5, iPhone X with iOS 16.4.1 and the aforementioned iPhone 14 Pro
The great joy of iOS 16.5
The exercise to see how reduced the battery was similar, that is, thirty minutes watching the same Apple TV + series and with autonomy charged to 100%. In this sense, the results are real, since, after 15 minutes, the iPhone X with iOS 16.4.1 was left with a autonomy of 63%, while the latest version of iOS had a 64% battery. . The difference is minimal Yes, but it shows that Apple has gradually improved a version that was born with many battery management problems and that new features such as the always-on screen, dynamic island, Widgets, and vibration considerably reduce the battery.
Regarding the temperature, the two iPhone X presented to the touch the same temperature than the iPhone 14 Pro, which shows that this update improved aspects such as the battery, but not problems with efficiency and temperature of the device.
By way of conclusion, it is important to take into account that this test, even if they use the same operating system, the battery condition plays a transcendental role, even above the iOS version. The two iPhone X have a very degraded battery that affects their performance, although Apple, as promised, gives them a little more of life to all its units that it supports.
