At the launch of the iPhone XS Max and XS, Apple claimed that the new smartphones can last up to 1.5 hours longer than it's predecessor. A recent test carried out by a YouTuber revealed that the iPhone XS Max can outlast most rival flagship phones when it comes to battery life.

The test was conducted by YouTuber MrWhoseTheBoss, where four phones were tested for battery life. The test included Apple's iPhone XS Max, Samsung's Galaxy Note 9, Google Pixel 3 XL and the Sony Xperia XZ3. 

To put things into perspective, the iPhone XS Max has a 3,174 mAh battery which was revealed from a regulatory filing. It is smaller than the smartphones it was put against, as the Galaxy Note 9 has a 4,000 mAh battery, the Pixel 3 XL has a 3,430 mAh battery and the Xperia XZ3 has a 3,300 mAh battery.

Even though the iPhone XS Max has a smaller battery life, it still managed to last longer than all of the other smartphones in question. 

In the test, all four phones ran a series of applications and games that would simulate everyday use on the smartphones. It was revealed that the Sony XZ3 was the first to die in a matter of three hours. 

Google Pixel 3 XL managed to survive for five hours and 20 minutes at which point the iPhone XS Max still had 11 per cent left. The Note 9 managed to last the longest at six hours and three minutes while the iPhone XS Max managed to last a few minutes longer.

It is worthy to point out that the Note 9 is capable of lasting longer than the iPhone XS Max only when the resolution is kept at default settings. The iPhone XS Max runs at a resolution of 2688×1242 which is higher than the Galaxy Note 9 (1080p). 

In order to run a fair test, the YouTuber cranked up the Galaxy Note 9's resolution to the maximum i.e. 2960×1440 to replicate similar testing conditions.
