How to Efficiently Keep an iPhone Battery Chargedby Avery Martin
The new iPhone 5 Lightning USB connectors are designed to use a trickle-charge technology to prevent overcharging your iPhone. While this prevents your iPhone from overcharging, and you could leave the charger in all night without degrading the battery, over time you would have better results if you charged your iPhone completely and then turned it off. You can also adjust power settings and configure other iPhone settings so that you don't have to charge your iPhone as often and prolong the amount of time you can go between charging sessions.
Select "Settings," "General" and "Software Update." Install any available updates. Updates can help your iPhone run more efficiently through improved power management and operating system enhancements.
Tap "Settings," "Brightness & Wallpaper" and lower the screen brightness to conserve battery life and prevent the need for continual charging. Additionally, you can turn the Auto-Brightness slider to "On" to conserve battery life.
Turn off notifications you don't need. Tap "Settings" and "Notifications." Select each app in the In Notification Center section that you don't need to receive notifications from and turn the Notification Center slider to "Off."
Tap "Settings" and "Mail, Contacts, Calendars." Select "Fetch New Data" and turn the Push Notifications slider to "Off." In the Fetch section, set notifications to a higher interval such as Every 30 Minutes or Hourly.
Select "Settings," "Privacy" and tap the "Location Settings" option. Slide the Location Services slider to "Off" or turn off only applications you don't need to use with Location Services.
Turn on Airplane Mode when you are sleeping, in an area that can't receive calls or don't want to be disturbed. Tap "Settings" and slide the Airplane Mode slider to "On."
Press the "Sleep/Wake" button on the top of your phone to lock the iPhone when not in use. This creates a more efficient use of your iPhone battery since the iPhone doesn't use as much power when not in use. Set Auto-Lock by tapping "Settings," "General" and selecting "Auto-Lock." Set an option to automatically lock your iPhone after a set interval of time.
Tap "Settings" and select the "Wi-Fi" option. Slide the Wi-Fi slider to the "Off" position when you are not using a Wi-Fi connection.
Select the "Settings" app and tap "Bluetooth." Turn the Bluetooth slider to "Off" if you do not use any Bluetooth-enabled headsets or other Bluetooth devices.
Connect the USB Lightning adapter to an Apple power adapter. Plug the adapter in to the wall and unplug the iPhone when it reaches a full charge. Press the Home button while plugged in to the charger to check the battery status.
Connect your iPhone to a computer via the USB port to charge when you are using your computer. This can save power by using the USB port to charge the iPhone. Disconnect any peripheral USB devices to increase the charging rate.
Avoid syncing or using the device while charging your iPhone. This can result in less efficient, longer charge times.
Completely charge your iPhone until it reaches a 100 percent charge at least once per month.
Unplug the iPhone from the charger and use your iPhone until it powers down by itself.
Recharge the iPhone to complete a charging cycle. This allows you to keep the electrons in the battery active and maintain the effectiveness and efficiency of the battery.
