In terms of battery life, the iPhone SE is said to perform similarly to the iPhone 8. Apple here employs a much newer and more efficient SoC in the form of the A13, while retaining the same battery capacity and display panel as the older phone. In essence, what we’re testing here is merely Apple’s calibration of the iPhone SE’s A13 chip in terms of its performance vs energy usage. Naturally of course, the new SE will have a more efficient cellular and WiFi chip as well which will contribute to the efficiency of the device.
