Save battery with Low Power Mode
If you know you're going to be using an iPhone for a long time, then switch to Low Power Mode by tapping Settings > Battery > Low Power Mode.
Low Power Mode reduces consumption by turning off a number of iPhone features. Mail fetches less frequently (push is turned off), Hey Siri is turned off, background app refresh is turned off and some visual effects are reduced. The screen goes dark after a shorter period of inactivity.
You may not notice the difference (although you may not get a vital Mail or Social Media message unless you check for it). On the whole, though, the iPhone works as normal and the battery will last for much longer.
