Battery life on many Android devices has been a problem for quite some time. Although the hardware and software in Android has improved much in recent years, battery technology remains largely the same. While there are some rumors out of better batteries being developed and more energy efficient hardware, that isn’t stopped many Android users from living charge to charge.
For HTC Droid Incredible users, it doesn’t have to be that way. XDA Senior Member PureMotive has developed a mod that aims to give Incredible users significantly longer battery life, and so far, the user response has been very positive.
The mod, which is laid out line by line for developers to use in their ROMs, tweaks a very large number of variables in the ROMs already existing sysctl.conf file. If one is not there, it creates on. Once done, PureMotive then explains what the sysctl.conf does, how it works, and why it works the way it does. Now, the cool thing is that many HTC devices all share a similar framework. While users may not be able to simply copy/paste this mod to other HTC devices, a developer could definitely change the tweaks to be compatible with other device, potentially helping many more.
For the entire mod and full explanation, head on over to the original thread.
