Battery life is one of the biggest selling points of the iPhone 13. The battery capacity of all four new iPhones is larger than that of the predecessor, and Apple promises to increase battery life by 2.5 hours. The reviews so far have emphasized the amazing battery life of the new phone, with the focus on the iPhone 13 Pro Max.
This is the largest group of mobile phones, naturally the largest built-in battery. A recent test showed that the battery life of the iPhone 13 Pro Max is the best of all mobile phones, easily surpassing the previous king Samsung Galaxy S21 Ultra.
The Galaxy S21 Ultra is currently a clear competitor to the iPhone 13 Pro Max. However, while we wait for the Galaxy S22 to appear, any flagship Snapdragon 888 processor of similar size with a 120Hz screen Android device can be used for comparison. YouTube channel PhoneBuff compared the two phones in a real-life speed test, and the iPhone 13 Pro Max is the unsurprising winner of these two phones.
S21 Ultra also appeared in a battery life comparison test on another YouTube channel. The test compares the iPhone 13 model with all other iPhones currently in stock by Apple. All the iPhone 13 surpassed their predecessors, and the iPhone 13 mini has a longer life span than the iPhone 12. The new record is the iPhone 13 Pro Max. Its battery life exceeds that of the Galaxy S21 Ultra. However, the S21 Standard Edition does not appear in this segment.

The battery life test of PhoneBuff shows the situation of two mobile phones side by side. A robot executes the same program on the devices participating in the comparison. This involves going through the app and performing the same tasks to see how they affect battery life.
One hour of phone calls, e-mails, Internet browsing, navigation, and video streaming. In different scenarios, some actions on the screen will change the refresh rate. Both phones support up to 120Hz refresh rate. And both screens can be dynamically adjusted and refreshed according to the type of content. Therefore, the dynamic screen helps to save battery life. Otherwise, the 120Hz screen will consume more energy.
The video also includes 16 hours of standby time between the two usage periods. In summary, the iPhone 13 Pro Max lasted 28 hours and 6 minutes, while the Galaxy S21 Ultra lasted 25 hours and 28 minutes. Abstracting the 16-hour standby time, the battery life of the iPhone 13 Pro Max is 12 hours and 6 minutes, while that of the Galaxy S21 Ultra is 9 hours and 28 minutes.
The battery capacity of the iPhone 13 Pro Max is 4352 mAh, which is a larger 5000 mAh battery than the Galaxy S21 Ultra. Another conclusion of the test is that the battery life of the iPhone 13 Pro Max also exceeds that of its predecessors iPhone 12 Pro Max and iPhone 11 Pro Max.
