When I start my day with my phone my ultimate goal is to get the most out of my battery. I have a Nexus 5 which is great phone but one downside is that the battery which is 2300mah can barely get you through the day. One way to help this issue is to under volt your CPU, the nexus 5 has a snapdragon 800 CPU clocked at 2.26GHz which is power CPU but at times it can run a bit hot and use more juice than it needs. By Under Volting your CPU your device will run much cooler without losing performance. (Warning if you go too low with the voltages your device will freeze and randomly reboot. ). The voltages than the nexus 5 ships with are a bit high I've been able to under volt up to -75mah without losing any performance however your experience may be different. To under-volt your device you need to have a rooted phone with a custom kernel installed. Franco, ElementalX, and Codeblue are few a few of the many kernels you can use with the nexus 5. I've been using ElementalX as my kernel for a while now, although Franco is also a good one. I use the ElementalX kernel app to manage my voltages, its a paid app but its definitely worth it. you could also use the Kernel tweaker app to manager voltages as well. I've set the governer to elementalx and i set the max cpu freq to 1574MHz, and the max screen off frequency is set to 729MHz. Don't go to extremes take small steps. Please let us know your results here.
This is what i have so far.
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 720mV
883MHz = 740mV
960MHz = 750mV
1036MHz = 760mV
1190MHz = 780mV
1267MHz = 790mV
1497MHz = 830mV
1574MHz = 845mV
1728MHz = 875mV
1958MHz = 945mV
2265MHz = 1000mV

Edit:
my pvs is 2
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 710mV
883MHz = 730mV
960MHz = 740mV
1036MHz = 750mV
1190MHz = 770mV
1267MHz = 780mV
1497MHz = 835mV
1574MHz = 840mV
1728MHz = 875mV
1958MHz = 965mV
2265MHz = 975mV

Most of the time adaptive brightness keeps the brightness at the right level however I I do wish you could adjust the sensitivity of it

Sorry for my sarcasm :)
BTW back to topic I use Code_Blue kernel and I lower voltage -35 wirh Synapse and my voltage is from 740mV for 300MHz to 990mV for 2265MHz

Just remember in a couple weeks if you notice stability issues or your phone rebooting, it's probably because of these changes.

Personally I value 100% stability, and I'm already able to achieve the same battery lifeout of default clocks and voltages as well as stock ROM and kernel. Such as these 5-6 hour SoT examples using 40% Adaptive Brightness.

Also I think you'll find lowering the voltages by 5-10% doesn't make a noticeable difference in battery usage, thought it should run cooler and throttle less.

With latest code blue and adiutor app cannot set 650mv for 300mhz and 422mhz, lowest i can go is 700mhz not sure why though. Thank you anyway, I'm trying this out.
