I'm so happy that @phonebuff mentioned this extremely important fact about battery tests And it's not just Apples internal testing. It's 9/10 battery tests on YouTube. They never touch the screen once which DOES in fact has a huge impact on battery life Every single time you touch your phones screen, it has to ramp up the processor to not just calculate the touch input, it hast to calculate predictably since you may not just be touching, but swiping. And it should continue scrolling once you lift your finger because that makes it feel more natural. And this needs power. Drains power. So a more important touchscreen and software can make a huge difference in battery life. And most battery tests just ignore that entirely. That's why some tests show vastly different results
