iPhone 17 Pro Max vs Galaxy S25 Ultra: which battery is better?

Apple itself indicates that with a fully charged iPhone 17 Pro Max you can play up to 37 hours of video. That is unprecedented long. But is the battery life of the 17 Pro Max in practice also better than that of the Samsung Galaxy S25 Ultra? YouTuber MrWhosetheboss picked it out.

In the simulated usage test of mrwhosetheboss, which includes scrolling on social media apps such as Tiktok and X, the Samsung Galaxy S25 Ultra a battery life of 11 hours and 58 minutes. The iPhone 17 Pro Max kept it no less than 13 hours Full. So that is more than an hour longer. In addition, we must state that the British version of the 17 Pro Max was used in this test, with a physical SIM card slot. The model with only Esim that is sold in the US, among others, has an even larger battery and will probably last half an hour longer. View the MRWHOSETHEBRoss test below:

The entire iPhone 17 series scores well

Although the 17 Pro Max is the undisputed winner, all new iPhone 17 and iPhone Air models did quite well. The Air was the first to give it up, after 7 hours and 18 minutes. Three hours later, the ‘regular’ iPhone 17 stopped. Moments later, the iPhone 17 Pro also became empty. After that, only the phones with a large screen remained.

Even Last year’s flagship from last year, the iPhone 16 Pro Max, beat the Samsung Galaxy S25 Ultra from 2025 in this test. The 16 Pro Max achieved a time of 12 hours and 15 minutes. This means that the battery life of the 17 Pro Max in practice is more than an hour longer than that of its predecessor.

Another test

The Chinese Tech Journalist Geekerwan performed a similar test with iPhones with a physical SIM card slot. His findings showed that the 17 Pro Max lasts almost two hours longer than its predecessor. Even the basic model iPhone 17 almost equaled the 16 Pro Max with regard to the battery life. These are the full results of Geekerwan:
