My current recommendations for battery life are as follows: 3.8.0 exp 1 (Lean Kernel)(imoseyon)

this started as an IRC question & i decided i'd like to have something as a reference for those who'd like to maximize battery life with their respective setups. Feel free to post some screen shots of your battery life to show others your sucess! :)

battery 101 - cut the services (not in use) off ! :)

How to configure Lean Kernel for optimal battery and secondly performance

Please download / flash your mods ROM / kernel / also flash lean tweaks (jakebites)

inside Lean Tweaks:
`enable 'File system speedup' (aka mount disc noatime)
`enable zram
`enable SD card speedup (set to base 2048)
this will all take effect once you reboot (it uses init.d scripts which require a reboot)
`Go to kernel menu > set customer vibration value > set vibration (/haptic) to 1000

install franco.kernel.apk
https://play.google....m.franco.kernel

Not only do I use franco.Kernel apk for access to Franco's latest releases, I also use it for functionalities:
Sqlite defrag on boot,
Disable logger
Set max freq for s/o
Etc!

go straight to system settings > more > *tick* NFC on [off]
next, disable logcats: liquid control > prop modder > *tick* disable logcats (also within franco.kernel.apk *tick* turn off logger)
liquid control > general > *tick* boot animation on [off] ; android bugmailer *tick* on [off] ; Check in service on [off] *tick*

best to manually toggle 3G / SYNC / LTE / GPS / bluetooth (obviously) as they are not in use - these are some of the biggest battery thieves unless you wantto use powersaver;

Power saver optimal settings:
~powermode: power saver / default
~by request (thanks terryrook) here are some preferred powersaver settings (top to bottom)
*tick* enable powersaver [on] off
Screen off action: *tick* [data off]
data action delay: [10 mins] (should be tailored to your preference (this is a great baseline)
Sync action:[ Autosync Off (delayed)]
Time Interval: [12 hrs] (i prefer this / + syncing each time i want my mail etc)
Screen-off Wifi action: [untouched]
Sync data usage: [Prefer Wifi]
Sync mobile data preferences: Prefer 3G

set your brightness with the slider to your liking - i stay in the area of 50%. Display = #1 battery hog

~Governor InteractiveX (interactive for additional stability)
~Max freq: 1650 (highest stable freq for your device) ( my thinking is the quicker the info is processed, the less processing time)(works for me) (you may want to experiment with this!)
~Min freq: 350 (as franco once said, less disatance between min / max = less time spent switching frequencies)
default IO sechduler

lastly for now, remmeber that your GPU settings will greatly affect batery life! i keep my gpu at 307 unless i dgaf about battery at time (for LK inside terminal simply type $su [enter]; $oc gpu 0 [enter]

if you're using set on boot, make certain that you have (lets say feature A) feature A set on boot for instance within either franco.Kernel.apk OR leantweaks. if you have feature A set on boot in both franco.Kernel & leantweaks, you will end up negating any battery benefits.. bc the system expending energy uselessly

I'm running these settings to the letter but I also know what works good for your phone may work like crap for mine, still very useful tips. There are a couple of things I wasn't able to find, one of them was in Liquid settings, it was... hang on let me check. Check in service. Is that in maps or something or are you on a 1.5 RC ?

Sweet man! By the way, thanks for turning me back to LK. I used franco again for one day and notice some decent battery drain, but the biggest killer for me is the fact that interactiveX isn't available. On LK with IX my phone runs super smooth at 230mhz, and while I am using my phone it just seems to drain much slower. Idle times are similar, but active use has a huge difference.

This thread wasn't created with the purpose of getting anyone switched to LK. That said, most folks here enjoy flashing different mods to their phones, ultimately i am just pleased that you are enjoying your device. Cheers!

Edit:
Going to be adding some snazzy dots / lines & other punctuation fun to clean up the OP :-D

also, in just for clarification, i wil also (tonight) be covering the rest of the possible tweaks / relevant settings that i mayve missed for the first post
