Apple’s newest iPhone model is still lacking in the battery life department. Enlisting a few system techniques can vastly improve the battery life on your iPhone and thanks to the iOS 7, there are even more ways to preserve your phone’s battery life.

1. Keep AirDrop turned off when not in use

AirDrop allows you to share photos and files with other users when they are in close proximity, but AirDrop takes a heavy toll on the iPhone battery, especially when AirDrop is in “discoverable” mode.

To turn AirDrop off, swipe upward from your home screen to open the Control Center. Tap AirDrop and select Off when you’re not using it.


2. Block unwanted calls

Calls drain your battery, even when you don’t answer. If you’re receiving persistent or automated calls from the same number, you can now easily block those callers from reaching you.

To block a caller, go to Settings > Phone > Blocked and then choose the contacts you want to refuse access. Keep in mind that while this feature blocks incoming calls, it doesn’t stop the caller from leaving you a voicemail.


3. Shut off the parallax motion interface

If you slowly move your phone from side to side in your hand you’ll notice the “parallax” effect of the three-dimensional icons resting on top of your wallpaper. This effect relies on internal hardware to sense the direction, speed and general motion of a user’s movements. This process drains your battery and while it’s flashy and interesting, it’s not a necessary function.

To disable the parallax feature, go to Settings > General > Accessibility > Reduce Motion, and flick the switch to On.


4. Disable the ‘raise to speak’ feature

Siri can be activated by holding the iPhone close to your face. The proximity sensor on the hardware of your phone is always checking to see if you’re nearby. This impacts the iPhone battery over the course of the day.

Disable the sensor by going to Settings > General > Siri, and tap the Raise to Speak button to turn off the feature. You can still activate Siri after enabling the Raise to Speak feature by holding down the home button.


5. Limit your notifications and the backlit display

Notifications on their own won’t cause your battery to drain, but activating the backlit display most definitely will. Applications update you with notifications to alert you to new emails, texts, reminders, etc. Some notifications are useful, but others aren’t necessary. You can easily pick and choose which notifications you want to receive by going into settings and setting some notifications to “silent” mode.

Go to Settings > Notification Center, and scroll down through the notification categories. For each low-priority feature you would like to mute like Photos or the Game Center, tap through each setting. Under Alert Style, tap None (the left graphic). Repeat this step for each setting.


6. Opt out of dynamic wallpaper displays

iOS 7 offers dynamic wallpaper options that adjust with hand movements, i.e. bubbles that float around the screen depending on how you hold your iPhone. These wallpapers consume much more battery power than its static counterpart. 

To choose a static wallpaper, go to Settings > Wallpapers & Brightness and scroll down. Tap your existing wallpaper under Choose Wallpaper. Either choose a background from the Stills category or select a photo of your choice.

7. Disable location system services

Location services rely on GPS for location-savvy apps and services. It’s helpful knowing where you on Google Maps, but this allows ads to target you based on your location and it auto-updates your traffic data. This means your phone is constantly pinging out to recognize your location. These aren’t really necessary functions and can amp up your iPhone’s battery usage.

Disable by going to Settings > Privacy > Location Services. When On, scroll down to System Services, then uncheck all of these items. When you’re not using Location Services, like GPS, switch it Off.

8. Turn on Wi-Fi at home or at the office

Wi-Fi should be disabled when you’re not using it, as it uses a considerable amount of battery life. But if you’re at work or at home, leaving the Wi-Fi turned and connected to a network can help in situations where your cellular signal is weak. 

Most phone batteries will maintain a stable discharge rate, but older phones like the 3G will have a battery life that decreases much quicker because it’s constantly pinging out for higher quality signal.

Swipe up to bring up your Control Center, tap the Wi-Fi button (second from the left). Or, go to Settings > Wi-Fi and set to On.

9. Turn off Bluetooth when you’re on the go or not sharing items

If you’re not sending out items to other users via Bluetooth, it should be turned off. Swipe up to bring up your Control Center, tap the Bluetooth button (center) off.

10. Reduce the auto-lock period to switch off the backlight

By reducing the time it takes for your iPhone to switch its off its display can help conserve your battery life. When you finishing using your iPhone and you set it down, it can take a minute or two (sometimes longer) for the display to turn off. This means the display can drain your battery while it’s not actively in use. 

To prevent this go to Settings > General > Auto-Lock, then set to 1 Minute or 2 Minute, depending on your time preference. The shorter the time, the higher the benefits to your iPhone’s battery.
