Optimal settings for an iPhone to save battery (my experience)

There are lot of articles telling you to turn off many features in an iPhone to save battery and this is not one of those. I have been changing settings and get a best battery life for my iPhone 5c and with the following settings I am easily getting a 30 hour usage on a single charge. You can also try this.

UPDATE: I have written another post on how to setup cheap portable wifi. Check here.
  1. Switch off the battery percentage indicator (Settings -> General -> Usage -> Battery Percentage) and do not check the phone constantly to see if you got a notification.
  2. Use a louder ring tone (Settings -> Sounds) so that you are notified and use vibration.
  3. Use Auto-Brightness (Settings -> Display & Brightness) and set the level to the minimum that is comfortable to you.
  4. Use smaller text Text Size (Settings -> Display & Brightness) suitable for you. This will help you to read faster.
  5. Group the less-commonly used icons in folders so that you can access the productive apps faster.
  6. Facebook is one of the battery hungry app. Uninstall it if you have, there are other important things you should care about.
  7. Check that you have given Location Services only for required apps (Settings -> Privacy -> Location Services). Enable the Location Services only for apps that is useful to you. To the bottom of list there is a System Services item. Click on that and enable the Location Service only for Find My iPhone only.
  8. Use Cellular Data in utmost necessity. At places of bad coverage, it drains the battery a lot.
  9. Make sure to switch off WiFi and Bluetooth when not in use and lock the display orientation (swipe up from bottom in the home screen and enable the last icon on the top row)
  10. Enable Push notification for mails (Settings -> Mail, Contact, Calendars -> Fetch New Data) only when you require. Otherwise set the interval to Hourly to get the maximum battery.
  11. Switch off sound and notification center display for unnecessary apps. Go to Settings -> Notifications and disable notification. You will still see the badge with the number of notification above icon. You can also opt to completely disallow notifications for apps here.
  12. Do NOT close the commonly used apps. This will drain battery.
  13. Use Do Not Disturb (Settings -> Do Not Disturb) suitably.
  14. An advice from Apple: Change the phone to Airplane Mode (Settings -> Airplane Mode) in area of low/nil coverage to save battery.
You may try changing these settings as you like and see how it works for you.
