you made this kernal based on doomloard and fxp>>>why you did not try to make one based one jason stien‘s kernals because he is a briliant in saving battery
and his kernals is the best of battery life

keep on your great work adrianom you are amazing

Strange, I'm having completely different results ...

In my tests with WiFi 100% of the time ON and screen OFF, I am having about 2% per hour.

Already with data 100% OFF (no WiFi, 3G or BT) my result is 0.5% per hour.

I am using BB .64 from LT18a (US), and my ROM is Stock .62 LT15i.

Is not to have such influence, but what is your Base Band? Which version of your ROM?

Thank you.

My usual setup is: Data always ON (2G only), Background Data and Autosync ON. No polling at all and the only apps that use Push are Gmail and WhatsApp.
WiFi OFF most of the time, unless I want to download something big.
My baseband is -64, stock .62 ROM LT18i.

iridaki,

Another thing I noticed in your picture, you had two major peaks of battery use, I could not understand their language, so I did not understand what they consumed so much in this period.

The rest had a normal consumption, only these two peaks is that the consumption was very large.

You could tell what was done in this period?

Thanks.

Those peaks were because I was actually using the phone, browsing Tapatalk and tweeting. Then I went to bed and woke up to see I've lost 30%.

Usually, on stock kernel, when I sleep, the battery graph line is almost straight, whereas on this kernel it seems to be steadily going down for no reason.
I don't know why this happens to my phone with all your kernels, but please let me know if there's anything I can do to help you find out. BetterBatteryStats show no weird entries either.

I'll charge my phone now and repeat the testing! I'll let you know!
Thanks for all your hard work!

Hi sami55,

Thanks for the feedback, I start using FXP and DoomKernel as basis, but now, I am making my on changes, and locking some other to.

I do not know the work of Jason Stien's, but I am take a look.

You phone is Arc or Arc S? You ROM is LT18i, so I'm assuming that is Arc S, maybe that's the different, my phone is Arc.

I will check whether any change in frequency table can influence based on the processor of Arc S.

Thanks for the feedback.

Can you overclock the GPU ?

doomed151 · Jan 31, 2012

Just flashed v1.6, performance so far seems good. I'm about to sleep, so expect a battery report tomorrow. Let's see if it can get that almost flat battery graph that DooMKernel v18-FIX1 manages to get.

There's still significant drain when the phone is idle. I lost almost 30% overnight when I usually lost 5-7% with my setup.

I got almost the same result with v1.6 and I'm on Arc S.
down about 30% during night.

Maybe an incompatibility with Arc S devices then?

Is my suspicion, but I picked up a frequency table of a kernel made specifically for the processor MSM8255T, which is the used on Arc S, and applied it on my kernel.

I'll test for a few more hours to see if work ok, if so, I submit a new version tomorrow.

doomed151 · Feb 1, 2012

Min: 245 MHz
Max: 1402 MHz
Governor: interactiveX
I/O scheduler: noop

As you can see, that's nowhere close to a flat line and there's quite a bit of battery drain. Performance is good though. The same setup but with DooMKernel v18-FIX1 would get me an almost flat graph.

Guys,

The frequency table that I whos test, make the Kernel very unstable, so is not worth.

I am going to try some tweak specifically for the S Arc, but I not have a Arc S, so, someone who have a Arc S could get the result of command "cat /proc/cpuinfo" on adb shell and send to me?

Thanks.

Well, that was the real reason why Odysseus turned back home

soumya_digi · Feb 2, 2012

245-1024 MHz
Data Off, Wifi Off
13% down in 7.5 hrs
ROM - acronium 6.1
Baseband 36

It would be great if we can get a battery life like this!!

Looks like a cool app! Mind sharing the name or the app itself?

The name of the app is ' Battery Consume'. Available in market for free.

Hello everybody,

Based on the kernel from DooMLoRD and FXP and wanting to make a more clean kernel in relations to Stock Kernel and add some personal changes, I make my own kernel that I am posting below.

He is based on 4.0.2.A.0.61_62 source kernel, and adding the follow changes:

v1.0:

New Governor Option:

SmartAssV2

Smartass

Smoothass

BrazilianWax

Interactive

Savaged-Zen

Scary

I/O Schedulers:

Noop (default)

Anticipatory

Deadline

CFQ

Overclock option to 1.9 Ghz

Enabled SWAP support

Enable some file systems:

EXT2

EXT3

EXT4

NTFS (Read & Write)

CIFS

DoomKernel Ramdisk:

With autorooting (prerooted)

init.d scripts/binaries execution support

support /sd-ext backup/restore

modCWM-v04 TouchEdition Recovery

and other (see http://xdaforums.com/showthread.php?t=1172885 for full changelog of DoomKernel Ramdisk)

Default Sony Xperia boot logo.

v1.1:

Have the same features that v1.0, only bug fix on compiler configuration.

v1.2:

Improve battery life
Change Sony source code base, now base on 4.0.2.A.0.61_62 source

v1.3:

Great improve of battery life by disable NETWORK_FILESYSTEMS (CIFS and NFS)

v1.4:

Enable CPU undervolting options (the kernel frequencies is not undervolted, but you can undervolt (recommend using IncrediControl)
WiFi undervolting

v1.5:

Disable duplicate voltage scaling frequency, for better manager of cpu frequency and better battery life.

From FreeXperia: salvage some more ram by removing unused pmem_adsp_cache

From FreeXperia: salvage some more ram by removing unused pmem_audio

Disable verbose procfs contents

Adding scripts for better battery life and overall performance:

Internet speed tweaks

Misc kernel tweaks

Battery tweaks

Journali smoff

Defrag DB

Loopy smoothness

Sick

Zipalign

Zipalign Defrag DB

Change sched_latency_ns to 600000

Change sched_wakeup_granularity_ns 400000

v1.6:

WiFi Power Management Tweak

Increase CPU voltage of some frequency for better stability

CPF Frequency Tweaks and Enable CPU AVS (Adaptive Voltage Scaling)

Revert: change sched_latency_ns to 600000

Revert: change sched_wakeup_granularity_ns 400000

Enable EXT3 and EXT4 Posix ACL and XATTR

Disable YAFFS ECC Check

Enable YAFFS empty lost and found folder at mount

Disable YAFFS block refreshing

Change pll2_fixup onverclock control

New compiled WiFi modules

WiFi modules included in Ramdisk

In general this version is for improve the battery life and resolve the problems of WiFi don't work because of user using not default WiFi modules (DoomKernel Modules)

Ps. For user with WiFi don't work just restart twice.

The instalation is the same from other kernel:

Code:

fastboot flash boot boot.img

PS.: for CPU undervolting I recomend using IncrediControl (https://market.android.com/details?id=com.incredicontrol)

I want to warn that THIS IS A TEST KERNEL, so he may have some bug.

Thanks. I probably cant work in the Kernel for a few days, but once I have some results I communicate.
