Here is a collection of ten handy tips to help you ultimately save the power of your iPhone, iPad or iPod Touch with iOS 7.
Tip 1: Turn off running applications unneeded.
The fewer apps are running, the more power is saved.
Tip 2: Adjust the brightness.
Lower the brightness or switch on Auto-Brightness in Settings/Display & Brightness.
Tip 3: Turn off AirDrop.
AirDrop will keep looking for other compatible devices if it is turned on, so you'd better turn it off when finishing transferring pictures or other files. BTW, to close it, you can swipe up on the screen to open the Control Center, tap AirDrop and choose Off in the menu.
Tip 4: Turn off Bluetooth.
When the Bluetooth is on, it always searches for signals, which consumes electricity to some extent. FYI, you can quickly turn it off in the Control Center.
Tip 5: Turn off Background App Refresh.
This setting allows apps to refresh their content when on Wi-Fi or cellular in the background, so you can turn it off in Settings/General/Background App Refresh to preserve battery life when it is not needed.
Tip 6: Close E-mail pushing service.
If you don't need to immediately get push notifications when receiving emails, you can go to switch off Push in Settings/Mail, Contacts, Calendars/Fetch New Data. Moreover, choose a fetch schedule from Hourly, Manually, Every 15 Minutes and Every 30 Minutes, and it is recommended to fetch less frequently for better battery life.
Tip 7: Turn off notifications for unnecessary apps.
In Settings/Notifications, you can choose the apps whose notifications are of little importance for you, and then turn off Allow Notifications.
Tip 8: Turn off Location Services.
Location Services uses GPS, Bluetooth, Wi-Fi hotspot and cell tower locations to determine your location, which consumes a lot of power. FYR, you can turn it off in Settings/Privacy.
Tip 9: Close dispensable System Services.
In Settings/Privacy/Location Services/System Services, you can turn off unnecessary services including Compass Calibration, Location-Based iAds, Popular Near Me, etc.
Tip 10: Turn on Airplane Mode.
Although you can't use your device to make phone calls, receive short messages and do many other things when the Airplane Mode is on, the power of the equipment is preserved to a great extent. Incidentally speaking, the Airplane Mode can be turned on in Settings or Control Center.
