which ROM (version)

4.0.1.A.0.283

which CPU frequencies u use (min/max)

245/1.4GHz

which governor u use

interactive

which i/o scheduler u use

noop

are u using 2g/3g/wifi/bt/gps

only 2g

wht was ur usage

1-2% per hour in standby

when was the issue encountered

Started after upgrade kernel from v10 to v11. Have not changed anything else on the phone. Did a full charge, a reboot and then left it on standby. CPUSPY show 98% deepsleep and battery history only show Cell Standby and Phone not active.

This is wierd as everything is just like v10, the same is shown for cpuspy and battery history as before. Nothing weird is printed in dmesg or logcat but battery in standby has increased.

I have data disabled and running with auto time zone disabled as well.

But besides the battery drain, there is no noticeable difference, everything works very good as expected from a doomkernel :)
[Xperia Arc Android Development] avicho:
I have also battery drain

I use your kernel and it works great except the battery drain. I have 'se tweaked 0.4' rom and and it happeneds also in 122/1.5 and also in 245/1.0 speed.. Plz your help..
[Xperia Arc Android Development] haimelf:
Can I flash the kernel using "kernel manager pro" app?? Or do I have to fastboot the kernel?
[Xperia Arc Android Development] loryb84:
sure you're right.

- stock rom 4.0.1.A.0.283

- baseband: 8x55A-AAABQOAZM-203028A-49

- Cpu freq: MIN 122 MHZ MAX 1024MHZ (no overclock)

- used set cpu and tried smartass v2 and ondemand with the same results on drain

- i'm using 3g with all switched off( bt,wifi,gps,data)

- in idle with screen and all turned off using stock kernel i got 1% consumption every 2 hours or more, using doomkernel I got 1 % every 30-40 minutes.

- I encoutered the issue once I installed v11 doomkernel.now I flashed back to the stock kernel and the battery drain is reduced again.

I attached two screenshot

- in the first one i had 3% battery loss in 8 hours using stock kernel

- in the second one i had 9% battery loss in 6,5 hours uaing doomkernelv11

Thank you, tell me if you need more information

@DooMLoRD

Your Kernel work with the last Stock SE 4.0.2.A.0.42 ?
[Xperia Arc Android Development] DooMLoRD:
yes it will work
[Xperia Arc Android Development] plopingo:
"it will" hum :p

[Xperia Arc Android Development] piflechien:
It works, I installed it on 4.0.2.A.0.42
[Xperia Arc Android Development] DooMLoRD:

[Xperia Arc Android Development] DemonicHawk:
Anyone else find their battery draining more than with the stock kernel? I usually get through the day with light usage leaving me at 40-50% and now its about 20-30% with this kernel.
[Xperia Arc Android Development] Tigrer:
I noticed more battery draining too...

Btw, GOOD work DooMLoRD, Thanks

:)
[Xperia Arc Android Development] Starwalker:
I have the problem, that the battery drain with DoomKernel v.11 is much higher than with stock or Blend Kernel, too, especially if the device is "sleeping".

I am using SE-tweaked rom v04. My clock speed is set (with SetCPU) to a maximum of 1.4 GHz, my governors are ondemand or smartass v2.

I really like the Kernel and the several improvements. It would be really nice, if there will be a solution for the battery drain:

Thanks for your great work and best regards

[Xperia Arc Android Development] ShyamSasi:
Yes actually! I seeing the same problem. I have set 122 Minimum and 1.4 Maximum with Noop I/O scheduler and Smartass V2. Using CPU Spy I can see it has entered into Deep Sleep still 65% battery from 100% within 6 hours
[Xperia Arc Android Development] Flo95:
Why do you guys flash the new firmware, what's better?

Hi Doomlord

I really need your help:

If to compare the 4.0.1.A.0.283 with 4.0.A.2.368, I see really big problem with Wifi.

I used 4.0.A.2.368 for about two months at CPU 1.9Ghz, all features (Wifi, CPU, USB, ...) worked really stable . However, yesterday, I upgraded the .283 FW I really encounter Wifi is entering into a loop (reconnects) at each 30 seconds. I wonder what could cause such Wifi issue.

Moreover, CPU at high frequencies seem less stable in comparison with .368 FW.

For example, the highest stable freq with the new FW seems 1.6 Ghz.

Think that, as I didn't change any settings with my modem (which I am using it as an Access Point), it's obvious that something is strange with the new FW.

Thank you if you help with the Wifi issue. (higher CPU is of less importance for me).
[Xperia Arc Android Development] DooMLoRD:
hi i dont really know why u are having the wifi issue...

on my ARC i had similar problem the first few hrs later it settled well and then i have a perfectly good connection now :)

abt overclock... well i am using new lower voltage values.... i have posted this a few pages back... if everyone is having issues i will revert back to older voltages in next release

4.0.1.A.266

Hi Guys,

I have not long got my Xpreria and I am looking at App2SD as a solution to my storage issue.

Will it be okay to install this kernel on 4.0.1.A.266 firmware or will I need to flash the LT15i firmware.

Cheers,

Matt
[Xperia Arc Android Development] DooMLoRD:
update to latest FW
[Xperia Arc Android Development] Flo95:
Works fine here :)

Just had one total freeze in the 2 days I'm using it, but I think it was caused by an app. After pulling the battery it works fine untill now :)
[Xperia Arc Android Development] Alfa Kenny One:
DOOM! :rolleyes:

I flashed your .283 kernel with succes. And ''chipped'' my Arc to 1700Mhz. Altough it can reach the 2000Mhz, 1700Mhz is the stabelest.

Above 1700Mhz it will crash and reboot.

Everything works fine too.

Much thanks for your work, I appreciate!:)

[Xperia Arc Android Development] Jygar:
On the Arc S (LT18i) 4.0.1.A.0.266 is the latest one for me, so I am assuming your mean the (LT15i) 4.0.1.A.238? Is it possible to flash that on a LT18i?

Last night after installing the down graded OC version 1011 I had to clock it at 1.4 to get it stable. After ½ a day the system had found it self and I was now able OC at 1.6 and now running very smooth.

For the first 12 hours I had a certain lag and a higher drain but it has now stabilized at same rate as old kernel.
[Xperia Arc Android Development] festa20:
My battery drain isn't too bad but it says it's charging but it doesn't . I out it on charge 5 hours and went up by 12% could this have anything to do with the v11 kernel DooM as I don't have my laptop to put old kernel on just wondered

I have the same problem here, connection to my rooter is good but i can't connect to the market or other apps who need internet

It's not related to the kernel I'm back to stock 4.0.2.A.0.42 Generic Trade Central Europe 1 (2.3.4) yesterday using WotanClient

Sometimes wifi works good , sometimes it don't and sometimes is very very laggy (my box is just 1M back of me) (tested on Numericable and free)

Don't know why :/
[Xperia Arc Android Development] jlmcr87:
A lot of battery drain why? I set the min to 122Mhz, And i haven´t use the phone in all night.

Official firmware night: 3-4%

Doomkernel v11 night: 20% of battery drain

WHY?
[Xperia Arc Android Development] zohaib0001:
OOOh God its drain battery so quickly

i have xperia arc 2.3.4_283

i install your Kernel V11, set cpu speed to 1Gh as original

in deep sleep mod i check my arc after 10 hours

its battery drains 20% oooh its too much

in deep sleep battery drains 20% just in 10 hrs....

please fix the bugs....in your kernel
[Xperia Arc Android Development] yamaki123:
this version (v11) seem to be working at the highest clock more often than the v10, even when using lightly.

perhaps, that is reason why battery drains more in the version v11.

anyway, DoomLord is Doom Lord :)
[Xperia Arc Android Development] Starwalker:
I also have the problem with high battery drain in deep sleep mode. Lost 12% in 5 hours and did not touch the device. With stock kernel I loose 2-3% using the same configuration (and both with 1 GHz clocked for test).

The kernel is really great, but the high energy consumption is a problem for me. Have not recognized this using v10 before. A fix would be great.

Thanks in advance and best regards

[Xperia Arc Android Development] jlmcr87:
Doomlord are you going to do anything related to the battery drain on v11?
[Xperia Arc Android Development] DooMLoRD:
before reporting any issues kindly mention the following:

while charging the cpu throttles to max frequency in the current profile so if u have selected higher frequencies it will drain battery and charging will be slow

well i havent introduced anything into the kernel sources to cause the battery drain which you guys are reporting...

try battery calibration cycles (2-3 times) this surely helps getting better battery life...

here are some tips which can help u guys out:
[Xperia Arc Android Development] jlmcr87:
I´m on 2g mode only, ondemand, min 122 max 1400.

I´ve wipe battery stats after installing the kernel

just wiping battery stats is the worse!!!

u need to properly do battery calibration cycles (2-3 at the minimum)

[Xperia Arc Android Development] Flo95:
What's the highest clockspeed/voltage that you'd call safe?
[Xperia Arc Android Development] DooMLoRD:
personally "safe overclock" is 1.4/1.5Ghz
[Xperia Arc Android Development] Flo95:
Ok, good.

And when you're using the stock voltage or 1150mV for 1.4GHz as I do it should be even "safer" if I'm not mistaken.

Just want to ensure I do not overclock it too much. I know it isn't the best thing you can do to the phone :D
[Xperia Arc Android Development] yamaki123:
the capability to use USB-OTG devices with v11 is awesome; besides, i have one question: may there any damage to my Arc or the function is stock-quality in this version (v11), and it would be safe for long period usage ?

i have tested and confirmed that USB optical mouse, usb keyboard works fine with Sony Arc through USB-OTG cable.

BUT, my flash driver can't be mounted although it had been recognized as "unknown" device. any help here ?
[Xperia Arc Android Development] DooMLoRD:
There shouldn't be issue for long usage but I have noticed that the USB port starts heating up. . So don't use it for long...

For USB mass storage the SEMC framework doesn't natively support this... Refer to my other thread for how to mount using USB-otg... All required commands are there...

for exact usb-storage mounting commands refer to this thread: http://xdaforums.com/showthread.php?t=1224676

my loud speaker missing issue:

1. boot

How to achieve good battery (works for me)

I just wanted to share my battery experience with you guys.

I have since reflashed the lastest .42 firmware on my arc. Followed by V11 (non test version) of DoomKernal.

I then wiped data, cache, and dalvik cache, as well as formatted by SD card to start fresh from factory.

I have removed a lot of running service (these are from my head so will not be exact names, i used titanium backup to remove them)

DRM Protected media scanner

Crash Monitor

Device Monitor

DRM client V2(new in .42 firmware)

Timescape (+ all extentions)

Irrelavant apps (Neo Reader, Lets Golf, Hot Shots etc)

I only use ONE home screen, and make use of folders on the one to acces my most needed apps, google search, with a life contacts and extended controls widget.

My CPU settings are as follows

I/O = Noop

Govenor = smartassV2

Overclocked to 1.2GHZ

I used Dooms stock voltages, then applied a -50MV setting using setxperia

I ran 3 stability tests (different types) for 15 minutes each, no reboots, no crashes, and no force closes.

I actually clocked back by 200mhz as when my device was running at 1.4 Ghz, battery life was really poor. 1.2GHZ seems to be the best compromise of performance and battery life.

But now, im looking to get at least two days out of it with average use.

I fully charged the battery after setting my phone up.

And after 11 hours, my battery has only drained 30%. Less than 3% per hour.

Bare in mind, this has been in deep sleep for the majority of usuage. But, i have used whatsapp, email, bug village game, and browsing during this period.

Bare in mind this is my experience, but, if you guys are looking to have better battery life, try the above, i don't think home screens eat battery, its more the running services.

Give it a shot, let me know how it goes.
[Xperia Arc Android Development] ShyamSasi:

Hi

I got a xperia ARC S, running the 4.0.2.A.0.42 firmware, bootloader locked for the moment

I would like to flash this kernel to improve my battery life, and also have app2sd , available on this link :http://xdaforums.com/showthread.php?t=1201902

So my questions are:

- Will i have root access when the kernel will be on my ARC (and by this way control with set cpu, remove system apps etc..?)

- What are the dangers of unlocking bootloader of the ARC? => Can i flash back to recover the phone in Factory state, for example, with the same firmware with flashtool or Wotan Server without risks of brick?

- Can i update or restore with PC Companion?

- It seems i will loose the OTA update (brick), is it right?

- I need to apply a file by recovery for app2sd, what recovery must i take and how to install it (fastboot commands?)

Thx for answers guys!

are these better than ur .283 v11 kernel in frist post ?? ??

can u say a brief change log abt these test kernel vs. first v11 kernel ????

u talked abt battery calibrtion in arc .... is it really usefull !??

and can u give me link of battery calibrtion thread !???

thX so much
[Xperia Arc Android Development] fabulous69:
is your battery life improved?

to calibrate: wipe battery stats, after flash,

with phone 100% battery

use the phone to have 0% battery left.

Put it off, charge it completely .

Put it on, use it again, recharge to 100% phone off.

2-3 cycles are ok ;)

Then you quite obvious have to start from say 1.4 GHz try out if everything work at that speed. If it does then go up 0.1 to 1.5 GHz. In this way you can find out at which speeds your Arc is working corret with all programs.

Hello, new Xperia owner here, got an Arc S a couple of days ago, replacing a HTC Desire.

First off, thanks for the kernel!

I'm seeing quite high drain in sleep mode (about 2% per hour) with v11, hopefully one of the test versions will fix that, I used to have less than 1% per hour on the Desire (AOSP 2.6.35 kernel). What average consumption should we get on the Arc / Arc S, in sleep mode, without drain issues?

Got a couple more questions, though :)

What's the default voltage table for the Arc S? If it's identical to the Arc one, what about the frequencies above 1GHz?

And what's the default maximum voltage? I'm wondering how far up can I push the CPU without increasing voltage over stock max value.

And one other thing: on the Desire, we had both SVS and HAVS available. Any chance we'll see HAVS kernels for the Arc, as well?
[Xperia Arc Android Development] DooMLoRD:
yes high battery drain is the only issue currently there in my v11 kernel... i think its cause FW sources i used... i am a little busy but will soon be posting the test kernels...

default (STOCK) voltage table on ARC/ARC S is fairly identical: https://github.com/DooMLoRD/Xperia-...ter/kernel/arch/arm/mach-msm/acpuclock-7x30.c

the table i currently use is this: https://github.com/DooMLoRD/Xperia-...ter/kernel/arch/arm/mach-msm/acpuclock-7x30.c

regarding svs/vdd control i have already posted details here: http://xdaforums.com/showpost.php?p=16610299&postcount=362

HAVS is planned for future kernels but isnt a priority...
[Xperia Arc Android Development] cezarL:

As for HAVS... no worries, I was only curious. As long as SVS is doing the job, I won't complain :)

with phone 100% battery

use the phone to have 0% battery left.

Put it off, charge it completely . " after using to 0% battery and turning off

then charge it completely and again turn on and use it to 0% battery and again ...

and i must do it for 2 or 3 times ...

right !??

And another Q

are u sure, it is exactly way to calibrate ARC battery !???
