Enable Low Power Mode
Apple has said iOS 9 is optimized to increase the battery life up to an hour compared to those previous versions. Especially with Low Power Mode, users are able to extend another three hours for using time.

To switch on, users can go to Settings> General> Battery> Low Power Mode. Additionally, the device will suggest you to open this feature when the battery is down to 20% or lower.
Manage GPS service

It is not until a user opens this app that all the software such as Facebook, Twitter, weather forecast or even Safari … also requires the location information. Users can turn off or limit this by going to Settings > Privacy > Location Services, then disable this application.
Disable notifications and connections if not necessary
After upgrading or reinstalling iOS, the device will automatically activate Bluetooth. Despite its low energy consumption, it would be a good idea to switch this feature off if you are not using. You can apply it all to other similar connections, especially when users leave a Wi-Fi coverage area.
Limit those applications running underground

Tips are given that you should enable Background App Refresh if it is truly necessary by going to Settings > General > Background App Refresh.

Or adjust contrast and opacity via Increase Contrast and Reduce Transparency.
Or if you want ringing as a notification and consider vibration feature superfluous, you may turn it off in Settings > General > Accessibility > Vibration.
Turn off automatic software updates
Since iOS 7, apps iPhone and iPad can automatically update the latest version of them from the App Store. To turn it off, users go to Settings > App and iTunes Stores > Automatic Updates Downloads and cancel items. Additionally, you can also turn off Music, Apps, and Books to save battery power.
Reduce the screen brightness

Even at 50% of the brightness bar, iPhone and iPad screen is still very bright. You should put it down to the point that it is not offensive for your eyes when viewing inside and then can increase it when going outside.
Turn off 3D Touch
Only iPhone 6S and 6S Plus have this feature. Although 3D Touch is one of the important upgrades on new Apple products, it also causes the device to drain its battery faster. To turn it off, users go to Settings > General > Accessibility > 3D Touch.
