Dim It
The brighter your screen, the more juice you're using. If you're in a dimly lit room, turn down your screen's brightness.If you use your smartphone to play music, lower the volume.
Stop Searching
It is great that you can use Bluetooth technology to connect your smartphone to a headset, or use Wi揊i to speed up the downloading of e搈ail messages. But when you're not using that headset or not near a Wi揊i hot spot, turn off those features on the phone.
Skip a Generation
Your smartphone is also continually looking for a cellphone signal. If you're in a weak signal area, your phone must work even harder to find one, decreasing battery life. If you know that there is no coverage in your area, turn off your portable device's mobile capabilities
Check Mail Manually
Mobile smartphones can check for e搈ail messages and instant messages automatically. Or they can be set to %26quot;push%26quot; notifications as soon as they arrive in your server's mailbox.
Both strategies can be power hogs. To increase your battery life, turn off push and increase the interval between when the phone checks for new messages. Or better, set up your phone to check for messages manually.
