you can do that if you modify the kernel and recompile it. alternatively, you may flash OC kernel made by other developers.

i am lucky, i got a "Faster" CPU. there is quite a big difference between "slow", norminal, fast and faster CPU. for example, at 1.5ghz the vdd for each CPU type (these are in the default kernel):

Slow: 1250000
Norminal: 1200000
Fast: 1150000

If you got a "Fast" cpu, in that freq, you save 8% power compare to the "Slow". It will not translate to pure 8% since this is just the cpu, other components remains the same.

For my phone, at 1.5ghz, i m just using 1000000 vdd. that is like 20% more power saving! i m using that as my default max speed, which can overclock to 1.8ghz if necessary during benchmarking.

i can probably push it higher if i change the thermal throttle from the default 60c to 75c. but i like to keep the system as "stock" as possible. i just change the freq table that is all for now... 

it's actually not very accurate if you test like that since battery discharge rate is not actually linear.

however, your observation seem consistent with the source:

faux kernel: https://github.com/faux123/mako/blob/jb_mr1...lock-8064.c:300


matrix kernel: https://github.com/mathkid95/linux_lg_jb/bl...lock-8064.c:237


matrix kernel uses less vdd = save more power. of cause, other factor such as CPU governor tweak, early suspent, hotplug, etc will play some role too.

hmm.. seem like matrix kernel lowest freq is 288000, which is even lower than default 384000.

the last time i tried that on SGW (single core phone), 288mhz is a little too slow; so, if you play music while switch off the phone, music breaking up...

may be the S4 quad core will be fine...

I'm getting it soon,so I think the only way to solve battery issue is flash ROM,I hope that can improve

can i just register the phone online with LG?
or the warranty card must be sent?

My highest Antutu score: 23647

- 1.7ghz
- vdd=1150000 (same as stock kernel vdd at 1.5ghz for "Fast" and "Faster" CPU)
- noop IO scheduler
- everything else, default, including fsync. for me, not worth to disable fsync just to get some extra speed. it is risky.

Even at default 1.5ghz, managed to get: 20741

At this freq, it's only using 100000vdd, phone runs extra cool and save more battery. 

Galaxy Note 2 benchmark? LOL... eat my dusk! (yeah, i like to pick on Note II, coz most clueless people call it the best Android phone)

Hi, new Nexus 4 user here. The phone is great but the battery drain a lot even I off most of the sync. Any one face this problem? (I am noob cause first time use andriod)

Thinking to do that also, still research on the root cause never touch andriod b4.

Download Nexus 4 Toolkit from XDA forum.

One click unlock,root and etc.

very satisfied with my current rom setting

ty bro, furthermore, if installment can use the rebate? ty

yes. can.
