Long time Franco kernel user, but with 4.4.4 I gonna try ElementalX since Franco kernel seems to be problematic, phone runs hot when browsing even after done some heavy undervolting and underclocking.

Download the flashable ZIP (100% stock if you want, but the lean one is good too) here. Follow instruction there, you can dirty flash (no wiping anything). It should work

This screen resolution race on phones is ridiculous. It needs to stop right now. Even 720p is more enough for the screen size. This huge resolution just eats batteries, and used up GPU and RAM to render things on it.

It's not the resolution is the problem, it's the battery life. If it didn't affect battery life then put any resolution they wanted

Faster charging equals hotter batteries during charging. Just don't use your phone during charging or it might stress your batteries shorting its lifespan

Hows your guys Nexus 5 signal strength? I would like to know because I found a fix for it, hardware mod though. Will post it later tonight

This is true, this isnt a PC where programs needs all the processing power. If you have program that monitor CPU state time you will see it rarely use high clock, at most it will hover at 1.4-1.5GHz because of input_boost_freq. Underclock and undervolt is the best way to get the most out of battery life.

Most of us just browsing, watching videos, listening to music and using messenger/email app that dont use much power in the first place. Unless its gaming or other intensive app then you need the processing power. Otherwise underclock and undervolt all the way.

If you buy a phone for its resale value you gonna have a bad time.
