For iPhone and iPod Touch users, poor battery life has always been an issue. The power hungry device drains most juice out of it’s battery to keep the wonderful display lit. While shorter auto-lock intervals and auto brightness for screen does help, it can be annoying due to permanent locking and unlocking of device, especially if the user is waiting for something to complete.
Enter ScreenDimmer. From the developers of 3G Unrestrictor and Firewall IP, this nifty little tweak for the jailbreak community saves loads from your battery by allowing you to dim the screen-brightness after a pre-defined time, or if you wish, turn the backlight off altogether (if you’re out in the sun this can work).
The application adds its configuration interface under the native Settings app, and has the ability to turn off backlight, dim it after a certain time, and exclude certain applications from this setting. It also does not dim the light when the battery is charging, or when some application is using the device (navigation software, video players, games etc). You can simply set the settings once, and notice how your battery lasts longer as screen brightness is no longer hogging it down.
ScreenDimmer is for jailbroken devices only, since it is available exclusively on Cydia Store for $0.99 via the BigBoss repository. It requires iPhone OS 3.0 or higher.
