The Samsung Galaxy S224 Ultra has an absolutely monster battery. Here’s how it compares with the iPhone 15 Pro Max. In my battery test, Avengers is played back on a loop until the phone runs out of battery. The screen is set to full brightness, and phones are on airplane mode, with Wi-Fi and Bluetooth off. All tests are filmed with new phones that have full battery health. #Samsung #GalaxyS24Ultra #SamsungGalaxyS24Ultra #GalaxyS24 #Apple #iPhone #iPhone15 #iPhone15ProMax #SamsungvsApple #Android
