Before I depart...an interesting tech question
So I'm going to get my Nexus 5 tomorrow...and my SGS3 will go up for sale. It was a great phone and the community here has been awesome. Big thanks to the CM developers and Ktoonsez for making my phone awesome!
I've been pondering something for a while about phones and custom roms, specifically AOSP roms on Samsung Touchwiz phones...
From my experience with laptops, if I load Linux on it, there is some hardware that just plain won't work or that doesn't work as well as it does when it has Windows on it. I've done every fix and loaded proprietary drivers and done just about everything I can do to make it work as well as possible, but it still falls short of Windows. This is plainly seen in battery life, with my best efforts I always lose 1-1.5 hours of battery life using Linux instead of Windows (not a knock on linux, I love to use Linux for certain things, I just have to use it with my power adapter).
I've been struggling to get good battery life with CM 10.2 on my SGS3 for some time now...I can barely get 8hrs with 2hrs screen on time with CM10.2 and Ktoonsez, undervolting and tweaking and all. I've done my research on wakelocks and energy usage and everything, but I just can't get it to go longer. So it the theory the same for the SGS3? Because it was designed for Touchwiz, it it practically impossible to get an AOSP rom to work as well/energy efficiently as a Touchwiz-based rom? And, as a curiosity, since the Nexus 5 is supposedly pure Android, will an AOSP based rom work just as well as the stock rom?
