Battery tests make iPhone XS Max one of the champions of the new generation

Ah, batteries. The bottleneck in the development of contemporary mobile technologies. The reason for our anxieties away from taking or powerbanks. The most volatile components inside a smartphone or tablet – sometimes too much.

With each generation, manufacturers promise worlds and backgrounds in the area, whether with bigger cells or with optimizations in the processor and system that, supposedly, will make our beloved smartphones survive longer out of the socket. But who is doing better in this story? To answer that question, we can turn to battery test videos on YouTube – and today we bring two of them with good copies of the new generation of mobile devices, including the iPhone XS Max.


The first test, from PhoneBuff, generated a controversy due to a factor that may have been decisive in its result – more about it below. Still, it is worth commenting on for the simple reason that he is the first in the famous channel to bring a new methodology to his battery tests: the operations were not performed by human hands, but by a robot, which guaranteed maximum precision in the time and actions of each task.

The channel test placed only the iPhone XS Max (3,174mAh) against Samsung Galaxy Note9 (4,000mAh) – both set to display the very same luminance on the screen, sound at a similar level on the speakers and with all apps previously closed. The result? The device South Korean won and maintained 37% capacity when the iPhone died – it still held out for almost an additional 3 hours in the test cycle. The tests were repeated 2x, with similar results.

However, it is necessary to mention the controversy that may put the results under suspicion: as the presenter himself stated in the video, the Galaxy Note9 did the tests with its standard resolution, of 2220 × 1080 pixels – the device’s screen, in reality , is 2960 × 1440 pixels and the maximum resolution can be activated in the settings, as a result of the battery lasting a little less.

In this case, the discussion remains: it is valid to test with the device at its standard resolution, which most users will never even change, or it would be more honest to change the setting to its maximum resolution – which Samsung even likes to advertise in your marketing material? Both sides have valid arguments, but to cover all scenarios, let’s move on to the next test …


The channel Mrwhostheboss brought together the two devices previously mentioned Google Pixel 3 XL (3,430mAh) and the Sony Xperia XZ3 (3,300mAh) in another test – this one, without the aid of robots, but with the Galaxy Note9 operating at full resolution. Again, the same methodology: activation and timed use of different apps and games, with screens and speakers on the same level and without apps in the background.

In this test, things were different. Sony was the first to die, after about 4 hours; the Google device lasted 5:20 am and the two archrivals of Apple and Samsung remained in the final battle, with a victory of the iPhone XS Max by a small margin – it held up for 6h16 in the test, about 12 minutes longer than the Galaxy Note9.

One way or another, the important thing is to know that the new generation devices (especially the creations of Apple and Samsung, which inevitably are the most popular) are basically equivalent in terms of battery technology and the like; so, whichever way you go, you certainly won’t find any major sources of dissatisfaction in that area. Right?
