Smartphone Showdown: How Galaxy S25 Ultra and iPhone 16 Pro Max Handle Extreme Heat

New York, NY – In a recent heat test conducted in the heart of Manhattan, tech reviewer Lance Ulanoff put the highly anticipated Samsung Galaxy S25 Ultra and iPhone 16 Pro Max through their paces under extreme summer temperatures. With the mercury hitting a scorching 98 degrees Fahrenheit, the experiment aimed to assess how these flagship smartphones cope with direct sunlight and intense heat. The iPhone 16 Pro Max was the first to show signs of distress, ceasing functionality after just four minutes. The device displayed a clear warning message: 'Temperature: iPhone needs to cool down before you can use it.' The Samsung Galaxy S25 Ultra demonstrated slightly more resilience, continuing to display its screen and respond to basic touches for approximately six minutes. However, it also began to exhibit overheating warnings, preventing the user from opening applications. 'It's closing apps,' Ulanoff observed, noting that while the screen remained active, the phone was 'non-functional' for practical use. Ulanoff emphasized the importance of protecting electronic devices during hot weather. 'It's really a reminder to not leave your phone just sitting out in the sunlight, especially during the summer,' he advised. 'Keep it in the shade. Keep them face down if you can.' The test highlights varying thermal management strategies between the two smartphone giants, offering valuable insights for consumers concerned about device performance in hot climates.
