Whether it's a T-Mobile G1 or latest Motorola Droid X, here's how to get the most out of your Android-powered cell phone's battery.
- Set display brightness to adjust automatically. Activating it means the OS will automatically dim its display in darker environments, including seemingly well-lit indoor rooms.
- Reduce e-mail, Twitter, and Facebook polling. Set your various messaging apps to "manual" and you'll instantly extend your device's battery life by a significant amount.
- Kill extra tasks. Each new version of Android has improved automatic task management. But, having a task killer like Advanced Task Killer around can help neutralize unexpected network access and lengthen your battery life.
- Turn hardware features off. It's great today's phones have GPS, Wi-Fi, and Bluetooth, but do you really need all three activated 24 hours per day? Just trun those off, when not in use. On HTC EVO 4G, just turn off 4G mode—a good thing, since WiMAX consumes extra power but has yet to blanket the country. On AT&T and T-Mobile phones, you can even turn 3G off when you don't need speedy Internet access.
- Dump unnecessary home screen widgets.
- Reduce RSS feed update frequency.
- Power Manager is a powerful Android app that helps you manage many of the settings we discussed in this article. If your Android device lacks a task manager, try the free Advanced Task Manager.
