If you haven't looked very carefully at the menu for the battery in iOS 10, then there is a very high chance of having missed a very useful new function, this one making recommendations on the actions we can take to improve the battery life of our iDevices.
In the image below you can see what the new function looks like, it has a special section available in the battery menu of the Settings application, Configurations, where the recommendations are displayed, along with a link to the section where we need to make the changes to improve battery autonomy in iOS 10.
In my case, iOS 10 recommends reducing the brightness of the screen to improve the battery autonomy, a sign that the screen is the one that consumes too much energy at the moment, a button directing me to the section from which the brightness of the screen can be adjusted.
Depending on how you use your iDevices, iOS 10 may display various other recommendations to increase the battery life of your devices, and following this section carefully could help you substantially extend the battery life of your iDevices.
