With PLSX rom and Semaphore kernel..

little bit better than the best i have got

Im using 3g, gaming a bit, chatting with Line..

Very good i can say.. :)
[Nexus 4 General] eugenioxx:
Here you can get velocity (just sing up with you Google account in the top-side of the page and download the rom)

https://drive.google.com/folderview...&usp=sharing&tid=0BzX_bRKRGmexa3pwSmVkMU04czA

After that you have to download the gapps here ( choose the package you prefer :stock full minimal and so on... )

http://xdaforums.com/showthread.php?t=2397942

After that if you are on stock or other custom rom go to recovery (twrp) and do:

- factory reset( wipe data, system, cache, dalvik cache)

- uncheck in mount section the partition "system" ( if you don't do this you may not be able to install the rom I think )

-select "install zip from SD"

-choose velocity rom.zip and install it

-do the same previous passage for gapps downloaded before

- finally do reboot system

If at the boot of the rom you find out that you have lost root download this package and flash it in recovery

Semaphore has the newest ondemand governor (the kernel dev actually contributed it back to the Linux kernel) and really does have the best CPU power saving. The only other Nexus 4 kernel I know that has it is MiRaGe.
[Nexus 4 General] sergiodg14:
One more question...im at the moment in purity rom+hellscore...in your opinion...would you describe the change like a improve?...and what kind of things miss this velocity rom? thanks...sry to be so annoying..:S
[Nexus 4 General] senthilrameshjv:
I follow semaphore and mirage thread but I don't see the Mention of this new ondemand. I might have missed it.

Could you please link to that? And do you know if mirage supports f2fs?
[Nexus 4 General] xenyz:
Here is where I posted it in the Mirage thread.

Mirage proper doesn't do f2fs, but the modded Mirage I'm using known as naruKa does.
[Nexus 4 General] senthilrameshjv:
Oh, not a fan of naruka color profile but being on f2fs I don't think I have option. I'm currently with ak kernel
[Nexus 4 General] eugenioxx:
Velocity rom boot up with art runtime ( the best thing of this rom with a lot of fix and merged commit so it's more stable than other rom in art runtime). It has few customisation less than purity ( it's very similar to pure stock rom plus some status bar things: battery icon, quick pulldown ...and not more)

This rom is very smooth and with stock kernel I made 5 sot and some minutes with a day of usage, but with other kernel like matr1x and franko I have similar good results. Many features in purity rom here are not present by the way.

I decided last weekend to make a new setup, it's still Paranoid android but the 4.3 Beta 2 and I'm using the last Franco Kernel.

I rode a lot of people getting more than 3 hours with this Kernel, but I'm hardly getting more than 2 hours.

Can somebody please help me to figure out why?

I was thinking about changing my battery, will it help ?

Thanks for your answer.
[Nexus 4 General] Kaka88:
I think it mostly beause of your brightness..

Did you using full brightness? Did the location and auto sync off?

With stock, its not surprise getting that SOT..

But you should get more with custom ROM and Kernel..

With PLSX / Velocity and Mirage kernel, im easily got 3h 30min SOT (4h average)

Do you play games? Try Hellsdoctor #2 R4, it should give you minimum 3hrs SOT

If you have 1-2h with Hellsdoctor too then:

I had world record battery on that kernel as well, like 5 h SOT on 3G only. I think it was the last one compiled with Sabermod.

Anyway, these days it's a tossup for me between MiRaGe ( or naruKa, modded MiRaGe) and ak's recent kernels. Both have good performance and battery, I'm trying to sort out just how much extra battery I get on mirage.

Hello everyone,

I have a finding,

I found that any rom can be fast and buttery smooth if it uses the processor too much.

But this drains the battery faster. And generate excess heat that is felt in the back of the phone.

However, some roms are very fast, without depending on the processors.

I can know if a rom is good when i find it fast , without the phone getting hot after some time of use (ex. 1 hour).

Just a thought ...
[Nexus 4 General] ggunzio:
What a great find sir. You deserve the nobel prize xD
[Nexus 4 General] aymnahmd:
LOL

I don't know you're making laugh at me or not.

But this is a simple finding,

Whenever i try a new rom, without waiting for full battery cycle i can tell it battery conservative or not.

[Nexus 4 General] omer7:
This underclocking could be due to throttling. You can check it in apps like trickstermod. If slimkat stock kernel is using stock google thermald, then it would start throttling when battery temperature reaches 37C.

But nevertheless very good battery time.

[Nexus 4 General] AJ205:
i dont understand users who give sot results when using the phone only on wifi. this is a cellular phone. its made to make calls also on a cellular network. whats the point of testing only on wifi? why not use the same principle as a car fuel economy test: city driving = 3g , highway = wifi, combined = both. it will be more helpful imo :)
[Nexus 4 General] xenyz:
It's more like a miniature portable computer that has a radio. You're using one frequency and power level or another to communicate during the day. This is how different people use their devices.

That being said, I've found that, on average you get roughly 50% more SOT using wireless than on 3g with similar usage. So you can do the math and go from one to the other.

I think it is reffering to the stock rom as the kernel of that custom rom = the velocity kernel because if he will write stock kernel people will think it is the kitkat kernel.

You're wrong. PSK is a different kernel, that is used only on psx/plsx. From what i know recently PSK KERNEL HAS BEEN BASED ON VELOCITY KERNEL in the latest builds because it's faster.

my first battery impression of the Nexus 4 was really good, running Stock JB 4.3 I managed to get up to 24 hours and more with 3G activated all the time.

Some day it seemed that my battery was getting weaker and weaker, so I tried flashing CM11 and several custom kernels in order to improve battery life.

Currently im running CM11-M6 with the Matr1x Kernel and I am able to reach over 24h hours battery life again. I greenified many applications like Facebook, Google+ and even the Google Play Services (according to this great tutorial: http://xdaforums.com/showthread.php?t=2357417 ) in order to safe battery life when the phone is idle. Additionally, I've installed an application called "CPU Tuner" which can be found in the Play Store. With the help of CPU tuner, you can set different CPU Profiles for different states. For example, I reduced the max frequency of my CPU to 540Mhz when the screen is turned off, so that the CPU won't be able to run on high frequencies when the phone is idle.

With this setup, I am able to reach really impressive standby times and screen-on-times of around 2-3 hours.
