3.Disable Location Services

Some apps keep tabs on your location that is also taking a good amount of battery power for your iPhone 7, even when you're not using them. Hence you can disable location service attempting to save battery.

Just head to Settings > Privacy > Location Services to toggle off the feature entirely, or limit which individual apps can have access to your location info.

4.Turn off Background Auto-Refresh

Background app refresh allows your apps to keep working in the background and constantly refreshing and updating their contents. It can be useful, but it drains your battery in the meantime.

To stop them from doing this, go to Settings > General > Background App Refresh and toggle Background App Refresh to off, or simply disable the app you seldom used.
