TEST NOTES: The devices were either purchased new or renewed by Samsung with original OEM parts and new batteries. The S21 Ultra was the only one purchased used; however, it had a recent battery replacement and is still at 100% health. Samsung's Renewed website only offered the S23 Ultra in an 8GB configuration, so it created a spec difference. However, it didn't end up playing a major role in this test. Screens were calibrated to 200 nits with auto brightness turned off. Devices are within an equal distance of a WiFi point. Tested in a temperature-controlled environment. Footage sped up at different parts for a better viewing experience. The S21 Ultra is not eligible for the One UI 8 / Android 16 update, so it was tested on One UI 7 / Android 15 — the latest software it supports. Software versions at the time of testing: Galaxy S21 Ultra: One UI 7, Android 15 Galaxy S22 Ultra: One UI 8, Android 16 Galaxy S23 Ultra: One UI 8, Android 16 Galaxy S24 Ultra: One UI 8, Android 16 Galaxy S25 Ultra: One UI 8, Android 16 Galaxy S26 Ultra: One UI 8.5, Android 16 SUBSCRIBE HERE: http://bit.ly/phonebuffsub FOLLOW US HERE:   / phonebuff     / phonebuff     / phonebuff   About PhoneBuff: It's not official until it's done #phonebuffstyle!
