[Nexus 5 Original Android Development] magnamentis:
in another place today :)

hi there, so today we meet here :)

ok to the topic, the battery life in general, due to better software based power management has dramatically improved with

kitkat, except perhaps a few exceptions from time to time. so what i'm saying is that it's great out of the box already and thus the

real differences are not that easy to distinguish accross roms and kernels like it was pre-kitkat. on the other hand, as far as SOT

is concerned there are still great differences in SOT and performance depending on the kernel, while in idle it's much harder to see.

now, since the differences have gotten so small, it takes a bit more work to find out and other factors like apps used, number of syncs

on battery, screen brightness, number of apps running in the background, thus number of apps installed in total, etc. etc. have

a much bigger impact on the different results which differ greatly from user to user. what you can do is to choose a standard

test (time) window, same place same apps etc. as much as possible identical and then let the phone do it's job and compare.

i do that during the night for 5 months now with several devices and i can say that the best configuration i currently have is:

Nexus 5

0.2 - 0.4 % per hour in idle, measured under identical conditions each night for 5 months. the worst configuration i had

deliverd a drain of about 1% per hour, as mentioned with identical conditions. only dt2w made it 2% per hour back in november

while it's meanwhile known that this is normal and cannot be altered with this device due to the chipset ( architecture )

the best result i get with CM11 M6 ( M5 was the same ) + elementalX 0.38. chaos kernel was good on battery as well

but there were minor difference which made me choose elementalX as my daily driver.

Note II N7100

0.1 - 0.3 % per hour in idle, measured under identical conditions, 10cm aside the nexus 5 with identical configuration

like the nexus 5, same apps, same syncing, same launcher etc. this goes as far as two different devices allow for.

this results i get with CM11 M6, ( nightlies gave intermittent results ) + AGNI pure CM 2.7.7. with settings published

by me in the n7100 CM11 thread recently. the worst result i got with that device was about 2% per hour drain

on CM11 nightlies but that stopped again after a few days, which simply can happen with nightlies.

i hope that this info helps you to find your top-configuration, should you need help with setting up a top configuration to

get top-battery life and flawless performance at the same time, just let me know.

before you ask about that i would recommend to read about tasker and greenify. if done well and with care this can

double your battery life, at least if you don't use the battery from 100 to 0 in one instance ( games or whatsoever )

but then anyway i recommend a solar charger ( just kidding )
