Samsung Galaxy Z Fold 8 vs Samsung Galaxy Z Fold 8 Ultra battery test!
 
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.
