This is in line with a battery test conducted by Mrwhosetheboss on YouTube, where he compared the entire iPhone 13 series against the previous ones to see how it improved, and the results are astounding because in the test, the iPhone 13 Pro Max managed to squeeze about 10 hours of battery (9 hours). 52 hours for accuracy).
Although the smallest of the iPhone 13 series, the iPhone 13 mini, lasted 6 hours and 26 minutes. Compared to older iPhones such as the iPhone 12, it only lasts 5 hours and 54 minutes, while the iPhone 11 only lasts 4 hours and 20 minutes. SE was frustrating with only 3 hours and 38 minutes.
It should be noted that this may not be referred to as a scientific experiment and does not imply global use, but it is clear that the iPhone 13 Pro Max battery is a monster and if you need a reason to change it, battery life alone may be a good reason.
