According to the Apple company, iPhone SE has better autonomy than iPhone 7, but only with regard to certain aspects of the daily use of the terminals. More precisely, the iPhone SE offers a longer period for surfing the Internet through 4G LTE networks, but also more time for listening to music with headphones.
iPhone 7, on the other hand, works better if we surf the Internet only using Wi-Fi networks, but otherwise it has nothing to brag about in front of its "younger brother". Those from Apple said that the iPhone 7 has better autonomy than the iPhone 6S, and this is completely true, but they said absolutely nothing about the iPhone SE, or other older terminals.
In the image below you can see the differences in terms of battery life for the two products and it was normal to expect the iPhone SE to have a longer operating time. Although it has a smaller battery, the iPhone SE also has a smaller screen, but it also lacks many other components found in Apple's iPhone 7.
Of course, the iPhone 7 offers much more new functions, so it is perfectly normal to have a slightly lower autonomy, considering the functionality.
