Turn off apps you don't need
Turn off any features you don't definitely need in order to save on charge cycles and keep your iPhone's battery healthy. These may include power-hungry functions like Bluetooth, Location Settings, Background App Refresh, and Push Notifications, all of which can be found in the Settings app.
Turn off location services
GPS and other location-tracking tools significantly deplete the battery life of your phone. Therefore, to preserve the energy life of your phone, it is advised to disable the "location" option from the "Settings" menu. Other components like Wi-Fi and Bluetooth also drain your phone's charge more quickly. You can always disable all of these features to improve the energy life of your phone.
