Real-world Power Tips
Understand that a battery-saving app that works great on one device might not accomplish much on another. Be sure to read user reviews for apps that work best on your handset. Also know that apps aren't the only way to save your battery. Just learn to be smart about when you're engaging some of your phone's gadgetry.
For example, turn off networking capabilities when you're not using them. Bluetooth and WiFi will constantly search for signals and drain your battery. Manage the update frequency of your apps. Some constantly search for the latest updates, which requires both CPU time and a network connection.
Dim your phone's screen. The highest brightness setting is probably unnecessary and it devours power. Limit the timeout delay for your screen, too. If your screen doesn't go to standby for two minutes, it's using a lot of juice for no reason. Limit the timeout to 30 seconds or less.
Many phones have their own integrated power-saving modes, too. Twirl through the settings or do a quick keyword search online and you'll have instructions for using any built-in modes on your device.
No matter if you save power manually or with an app, keep tabs on the way your phone uses power. An app called Carat, developed by the University of California, Berkley, performs an in-depth analysis of your phone's systems and offers recommendations for improvement.
Or, you can look for an extended-life battery. With many smartphone models, you can buy such batteries which last much longer than standard batteries.
Sure, smartphones inevitably need a whole lot of power. After all, they offer a nearly limitless number of capabilities in a pocket-sized machine. It could be years before battery technology catches up to your smartphone's power need, but in the meantime, you have a whole range strategies for conserving life at your fingertips, including battery-saving apps.
