Battery life is one of the most important features of a smart phone. You could have a phone that does everything but what good is it going to be when the battery is dead in an hour? Here are a few tips to help you extend the life of your battery.
1. Turn off WiFi & Bluetooth
Turning these options off when not in use is probably the biggest way to save your battery. With iOS 6 & lower, this is a pain. Once iOS 7 is released this fall, it will be much easier to do. For iOS 6 & lower open Settings, tap on WiFi or Bluetooth and tap the toggle to turn the service on or off. On iOS 7, swipe up to activate Control Center and tap on the desired service to enable or disable.
2. Lower Screen Brightness
The screen on your smartphone uses the most battery. I know above I said the WiFi & Bluetooth were the biggest way but lowering the screen brightness may not be an option for some people. For iOS 6 & lower, open Settings app, scroll to Brightness & Wallpaper and change your brightness. For iOS 7, activate Control Center and adjust the slider under the quick settings.
3. Turn off LTE
If you are in an area where your service provider has spotty or no LTE, then you should absolutely do this. Your iPhone will default back to 3G only so you will still have data connectivity but on the slower network. This only applies to iPhone 5, iPad mini and 4th Generation iPad. Open Settings, chose Cellular, flip LTE on/off. If you will be in a total cellular dead zone, you can also turn off the cellular radio.
4. Turn off Location Services
Location Services provides apps on your device with your GPS location. Turning this off will make apps that rely heavily on your location useless, like Maps, Foursquare etc. Open Settings, then select Privacy, select Location Services and toggle on/off.
5. Change Email to fetch from push
Most email accounts on iOS are defaulted to Push email. Your phone is basically refreshing all the time when set to push. When you change to Fetch, your email is only updated when you open the mail app. This is good because it saves your battery but bad if you are a heavy email user. Open Settings, scroll to Mail, Fetch New Data, turn push off and select Manually for Fetch. You can click on advanced to change the settings for a specific account.
Following these simple steps will help you extend your enjoyment of your iDevice. You may also want to consider investing in an external battery pack. You can search on Amazon and narrow your choices down based on size, price and how many usb ports the pack has. It also helps to keep a power brick and sync cable with you at all times.
