One Power Guard Battery Saver App Released Free on XDA
Getting better battery life is a struggle most mobile device users will have for the foreseeable future. Even if advanced batteries are released that give users two days of heavy use, there will naturally be a script, an application, and a kernel tweak to improve this figure further. As batteries get better, so do battery applications. Now, a new tool has been released that’s looking to be the best.
The application is called One Power Guard. Made by XDA Forum Member fonter, it is designed for rooted and custom ROM users. It brings an all-in-one approach to battery life and phone tweaking. You can adjust pretty much anything, including the I/O scheduler, CPU governor, CPU over- or under-clocking, settings tweaks, and more. There are also six modes you can choose from that tweak your phone for you. They include:
AI Mode: It intelligently adjusts cpu frequency and optimizes kernel to greatly extend battery time according to system loading.
Powersave Mode: It runs devices under low frequency to extend standby time.
Game/Video Mode: It provides flow game and video experience while offering satisfactory power-saving strategy.
Call Mode: It powers up the core function of phone conservation. For business persons trapping by phone.
Standby Mode: It lowers system frequency and prolongs stand-by time to the extreme. For sleepers and dreamers.
Custom Mode: It indulges pros to customize cpu frequence, scheduling and io adjustment, and to choose parameters of their own.
It’s a really nice application for those who don’t want to re-tweak their phone after every ROM flash and those who don’t know how to tweak their phones manually. For additional information on how each mode works and download links, check out the original thread.

But since it is a NVIDIA device, it does things beyond the simple streaming and gaming that is expected in this age. The SHIELD can locally run and stream 4K content to a capable TV. It is compatible with existing...
