iPhone and Android battery life tips

Here we conclude five tips for saving your iPhone and Android battery life and tell you why they work. You may have already heard some of them, but some are new. Tip 1: Turn off the feature you aren’t using This might be obvious to some, but this is one of the biggest causes of fast battery drain. Turn off the radio features in your phone you aren't using; even when they are idle, they suck power. That means switching off the WiFi, GPS and Bluetooth when you don't need them. Tip 2: Turn down the screen brightness. The screen is the biggest power sucker on your phone. Keep the brightness low whenever you can and set the auto-lock so it turns the screen off when you aren't using it. The iPhone and Android phones also have auto-brightness settings, but you are still best keeping the screen in the 30 percent to 50 percent range if you can. Tip 3: Kill the apps you aren't using. Close apps you aren't using, or at least some of them. iOS and Android phones do a decent job of not allowing all open apps to suck your battery, but keeping more than 10 open is never a good idea. On an Android phone also kill the widgets you don't use; even if they look pretty, they are constantly updating and draining your battery. And for those who don't know, on the iPhone, you can close apps by double-tapping the Home button to bring up the open apps. Then swipe up to remove the ones you don't need. Hit the Home button when you are done. On Android phones, you can go to the "Manage applications" area in settings or you can select the open apps menu and swipe to close the app. Tip 4: Turn off or limit notifications. Notifications are very useful, but they can also tax your battery. Be smart about which app notifications are enabled. Do you need notifications from your recipe app or Yelp? Also make sure those apps that are always busy -- like Twitter or Facebook -- aren't always refreshing with new updates and notifying you of them. With email, make sure you don't have notifications enabled for every new message. Tip 5: Buy a mobile charger or battery-equipped case. The aforementioned software adjustments will help, but they will only go so far, at least after a day of heavy use. If that extra juice doesn't go far enough, take the plunge: buy a mobile battery charger case to have on hand. There are a number of mobile chargers with Micro USB or Apple charging connectors, which makes the phone pretty chunky but also doubles your battery life.
