Display power consumption is currently the most important determinant of how long your phone or other device with an OLED screen last on a charge. With mobile chipsets going down to the current 5nm production process, their average power draw isn’t what determines battery life unless you are playing heavy 3D games for a prolonged period of time.
For everyday usage, your phone’s battery life mainly depends on one thing – the display – and the technology it is built with. Samsung’s top LTPO OLED displays that are now in the iPhone 13 Pro or Galaxy S21 models are made with the latest 6th-gen screen production process and have significantly lower power consumption than, say, the iPhone 13 LTPS panel, despite their high refresh rate abilities.
