PowerNap is a script specifically designed for the ZTE Warp which can significantly increase battery life. It made its debut in the Warp OEM ROM and accomplishes its magic by automatically disabling the data connection and restricting the CPU speed to an upper limit of 244MHz when the phone's screen shuts off. When you resume using your Warp, the script then restores your previous CPU speeds and re-enables the data connection. As only the 3G band of your radio is powered down, you can still receive calls and texts while PowerNap is active. You need to be running a custom kernel which supports asynchronous scripting (e.g. init.d2) to use PowerNap. Installation is easy, just download the script, place it inside your init.d2 folder using your favorite root-enabled file browser, and reboot. Downloads: PowerNap The original battery saver script. You may notice some lag upon wake with this version. PowerNap v2 Version 2 eliminated the lag which some users noticed with the original and also removed a condition which could cause problems with restoring the previous CPU speed. PowerNap v3 The latest in the PowerNap family, this version also governs the 3G connection to push more life out of the battery. Bug reports are welcome (especially with v3 since it has not yet been tested outside of my phone ) and as always... enjoy!
