[Q] Kernel for CM7 and Battery calibration - Xperia Arc Q&A, Help & Troubleshooting

Hi all
I recently unlocked the bootloader of my arc (that was scaring lol, im was so afraid that my arc would be bricked but luckily it didn't ) and flashed CM7.2 to it. However, I don't know which kernel should I use with CM7. I found from the Internet that there are 2 possible kernels(?) which I can flash:
1. The one comes with the package of CM7.2
2. DooMKernel CM7here
I am now using the one comes with CM7.2, and I tried DooMKernel CM7, only it supports boot sounds. But which kernel is the best that I should use with my arc? Please advice
Also, I found some webpages/forum posts telling that battery calibration is needed after flashing CM7, is it also necessary for arc?(Also, how to do so?) Because I found out that battery "drain" is worse on CM7 but I don't know if it is only a problem of calibration but not actually drain.
Thanks a lot
Ivan

better use kernel inside the package cause doom cm7 no longer maintain(still waiting for new version from doom),i read from internet that when you flash a new rom,it will think that your battery is in full condition,even if it is actually 50% or less,so calibrate it(search google),and try 3 or 4 cycle(charging and discharging) till get the best batt life,gd luck

I took all of the steps with various kernels and had serious drain on mine with 7.2 10% / hr, idle with screen off. I found that 7.1 from cyanogenmod had no problems for me.

Same problems with several Roms (Battery, shutdown, radio)

I try now since 2 moths running Android on the Kaiser with full performance.
I fixed several problems, but there are still some which frustrates my really!
1. The Battery lifetime is very short. The battery indicator in the homescreen reacts very slow, so it could be possible that I leave my home in the morning and the indicator shows a full battery. During the morning the Kaiser shuts down because the battery is empty. If I try tio charge it and connect it to the charging unit the charging process runs. When I disconnect it several hour (approx. 5 hour) later, on the display appears the massage that the battery is still empty. The problem is nearly the same with different Roms or Different Kernel. I never had this problem with Win Mobile.
2. I have a bad Radio performance. I tried several Radio Roms, but I couldn't fix it. Are there any possible values I have to change tio get a bvetter performance? When I have my HD2 next to the Kaiser it has each time a good Radio and the Kaiser has no Radio. Is it normal that the Kaiser has a worse Radio tehn the HD2?
I'm running at the moment the .25. Kernel with the update. But I had nearly the same problems with the .32. Kernel. Just the radio performance is a little bit better with the 25. KErnel then with the 32. Kernel.
I thik the problem could be at the kernel, because the problems are similar with each Radio Rom. Can anybody provide me a source with I kernel I can install which he knows thet the kernel will work very well?
I will have a stable Kaiser with Android and full performance. Thanks in advance for the help!
Can somebody help me please?
Change the kernel to possible an older one. And mind to use Kaiser specific kernel. Plus, What build you are using ? maybe possibly the instability of the build
Thank you very much for the feedback!
I tried the .32 kernel and the .25 kernel With the .25 kernel, I had a better performance the the .32, but not the full performance! Can you please help me with a link with a kaiser-specific kernel? Maybe I had the wrong one, but 'm not sure which one is the right.
I've tested several builds. The most stable ones were:
- not so super RLS 18 and
- My Modified Fresh Froyo Release 20-2-2011
But I had with both ones the problems as described above...
Battery status not working correctly eather
I have the same issue. Using the last kernel .32 and android 2.3 but have the same performence on 1.6 and 2.2 After a day my battery go to 70% decrementing smoothly with -1-2%. And after a day go from 70% to 15%. That is annoying do you have a fix for that?
Thanks
Until now, I didn't find a solution!
Does anybody have an idea?
At the moment I think whether I'll switch back to WinMo 6.5...
I found a solution!
I tried the following kernel:
2.6.32.9 [email protected]
In my opinion more important: I tried it before with an to 450MHz over-clocked kernel. Now I tried it with the mentioned kernel without overclocking and everything works!

Best Desire ROM for optimized battery life?

Hi all,
My partner has been experiencing a few issues with her 'stock' Orange branded Desire, not only being affected by calls dropping and Data being unreliable [sometimes works, sometimes doesn't], but also pretty poor battery life.
On that note, we think it may be a good idea to root her Desire and apply a custom ROM. Are there any ROMs out there which specifically target battery optimization?
I am assuming a new ROM/radio will help resolve her call/data issues, so battery is the next priority to look at.
I'm thinking CM7.0.3 is the safe bet [moreso because that's what I'm running on my Legend ] but is there a ROM out there in the Desire community known for great battery performance?
On a side note, if you can also recommend the best radio to flash [unless it's part of a ROM already] that would be cool.
Thanks in advance,
c_man
At first reducing the brigthness-level, turning off 3g/hsdpa, gps and wifi (sleep policy to "never" [settings > wireless & networks > wifi settings > press menu > advanced and set wifi sleep policy to Never; press menu and save) and only turning them on when needed will improve battery life.
A rom with a good battery life is redux:

I have installed it myself with the kernel in my sig. Especially the standby-battery-power is really impressive. IMHO all small aosp-roms like e.g. cm7, devnull, oxygen or redux will have good battery life. Furthermore, i good kernel with appropriate settings becomes important.
But final one can say, the battery life is most related how much you use your phone.
Hope, this could help you.
If your wife is used to the Desire as it is (inc. HTC Sense) then I would highly recommend LeeDroid.
Its well indexed and offers good battery life. The fact that it's based on Gingerbread (2.3.3) is a big help for battery. As far as I know Orange Desire is still on Froyo?
The big benefit with LeeDroid is that if your wife isn't as keen on trying to learn to use stock and likes HTC Sense, she will not notice any difference. It would be worth putting an ext partition on the SD card as well so she wont run out of room for apps.
I have installed 7.0.3 and my battery life drains super quick. All i have enabled is mobile network. So if you ask me.. .I would say CM 7.0.3 is not a very good batt saver.
Im using Redux at the mo
3ma drain on standby with GPS and BT enabled
ManU Havs Axi kernel undervolted with Vipermod
I found GV to be very good on battery drain too...
In all fairness you wont believe the difference in battery life between stock and a custom rom imho
Thanks for the replies so far.
@MatDrOiD - thanks, currently its between CM and Redux.
@JokerNJ - She doesn't mind having to use 'pure' Andoird, she's used my Legend on CM7.0.3 and know's its not massively different. We'll take a look at LeeDroid...
@alexander7567 - this is not what we wanted to hear. CM7.0.3 has done wonders for my Legend...

Positively or negatively!?
@MatDrOiD - you mention that you run Redux with Kernel: 2.6.35.9-Redux-SVS_BFS + ULV-Script.
Is there a recommended kernel for Leedroid and also for CM7.0.3?
This is slightly offtopic but can you supply a link on how to install/flash a kernel? I've not done this before [for my Legend].
Also what radio should I go for her Desire?
EDIT:
Doesn't matter if the radio and kernel you suggest are not the latest/greatest/cutting edge, but as long as they are stable and known for good performance, that is good enough!

Mobile network is one of THE battery killers at all. Turn it off and just turn it on, when you really need it.

I do not know a recommended kernel extra for leedroid. For CM7 (or aosp-roms in general) the manu-kernel is very good:
http://forum.xda-developers.com/showthread.php?t=883598
Furthermore the couttstech-kernels are very good (they can be used for sense-roms as well:
http://mirror.couttstech.com/android/index.php?dir=bravo/kernel/
But i would say, search for the corresponding threads of this roms, i think you will find a good kernel.
Flashing a kernel is very easy:
1.) Download the kernel you want to flash as zip and copy the file without extracting on your sd-card
2.) Go into recovery
3.) Do a nandroid-backup, just in case.
4.) Wipe cash + dalvik-cache
5.) Flash zip rom sd-card like you would flash a rom
6.) Reboot
You are done.
I would recommend to use this radio, which is the mentionend recommended radio in the corresponding thread for the rom. E.g. for leedroid it's 32.56.00.32U_5.17.05.08. If there isn't mentioned any recommend radio, just use the radio which comes with the rom. Nevertheless, you are free to update to the respectively newest one:
http://www.mofirouz.com/wordpress/2011/03/htc-desire-radios/
You flash a radio like you flash a rom or kernel. But when you do this, DO NOT TOUCH YOUR PHONE UNTIL IT'S FINISHED. With flashing the radio you update your desire's hardware. If there somehting goes wrong, your desire will be bricked probably. So before flashing the radio, check the md5-sum of the downloaded zip.
Thanks! I didn't know the method to flash a kernel was the same I've done radio before for my Legend so that's all good.
Now all that is left is for my partner to choose a ROM and away we go...!

You are free to choose. But this is the recommmended and most used one (also by developer).
Danke schön...!
Fingers crossed for the root [will use unrEVOked 3 - this shouldn't be a problem even though her Desire is Orange branded as I understand it - someone please correct me if I'm wrong]
You Desire guys are lucky to have so many ROMs/Kernals to choose from.
For us Legend guys the choice is almost made for us [and I sold my Desire to own a Legend ].
Another vote for LeeDroid here for the Desire. I have been using LeeDroid since I got mine and have never had a problem with my battery life at all. I can go for two days at normal usage without a charge. Even with heavy use I can go a whole day. I charge mine each night in a dock on my bedside.
Thanks FlareHeart, is that running the radio/kernal that arrive with LeeDroid too? No other mods?
Now it's up to her to decide if she wants a ASOP ROM or one based on Sense .
Hopefully we'll root tomorrow...
I used Amethyst a bit before the dev jumped ship to Nexus S. It used Coutt's kernel for it and the longest I got out of a full charge was 2 days. And that was general usage (few texts/phone calls a day, push email, Facebook/web browsing).
Using Oxygen now and I frequently get over a day and a half on general usage with thalamus's kernel.
best Rom for desire
I have used devnull then gingervillain, all vanilla roms. but without sense there is no sense!!. thus I went for insertcoin 1.0.5. which is stable, very nice. u need ext4 partition. 500 mb ok. use minitool partition wizard for Windows. everything is working fine.

What Leedroid version?

[Q] Newbie: any advice on wich ROM should I use?

Hi!
I'm going to flash my green lens defy for the first time, but I've some newbie doubts.
I'm having some problems sending SMS, people receiving them get only a few words of it and battery drains quickly, that's why i'm flashing.
I don't use the defy for playing or multimedia, only phone stuff, camera and gps.
Wich ROM do you recommend me? I'm looking specially for battery life and stability.
Any tutorial on how to install it?
Thanks!
Plenty of rooms and tutorials I was on sea15 froyo that was pretty stable everything worked but recently I'm running cm7 rc0 which I find 10 times better than sea15
Search the forum for Nordic and cm7 rc0 heaps of Info that will help you decide
yes you can try cm7 and various other things....but in the end you will be back on stock...till some proper final version of cm7 is released

Best kernel xperia S CM10?Battery life...

Hi guys,
i know that this question been asked already but being not so smart would like to ask first before doing anything..
Running CM10 FX210 on xperia s at the moment everything seems fine pretty much it's just battery seems similar to official ISC ..main reason for using custom rom was to improve battery..now I've been reading that there's few other kernels you can flash in recovery with better battery life..problem is which one i dare to use..some people getting stuck on bootloops after flashing ...also people suggesting that should stay away from custom roms such as CM because they use more of battery since they preform really good..maybe I shold try any stock rom?Any suggestions?
appreciate any response on this silly questions...
p.s. so my point just need rom or kernel for cm10 with good battery life...no need for playing games or to be superfast etc...:silly:
The only custom kernel for CM10 I think is Nova... It should be better than stock but... The best is relative. At the first 4 versions of KA kernel, for example, most people loved it, phone was way better, but mine never liked it... So it wasn't the best FOR ME.
thanks for reply mate..
I'm trying to download latest which is NovaKernel-nozomi-1.6.zip but it doesn't want to start download..any mirror link for this?
Should i go for latest or read somewhere that 007 version is the best battery friendly but seems way to old to 1.6?
one more question..
How to install stock rom over CM10 in my case? Do I have to use flash tool as well just put zip on phone and flash it?
thank you...

Go ahead with nova 1.6, it was giving me great battery life on aokp ROM.
Using the stock CM10 kernel. Battery life is much better than stock ROM / Kernel.
I use WiFi only when needed, 3G is off and brightness is 50%. Don't use much CPU except for a handful of widgets.
Will try Nova too.
I would recommend you the Nova Kernel
Switch your governour to "intellidemand".
I got appx 3 days with 4-5 hours screen time, by using 2G when screen is off and flight moder over night for 6 hours.
I can recommend Nova and KA as any othes of you, too =)
So Nova is the best .

best rom cm9 / cm10 / cm11? battery friendly?

Hi guys
I have this galaxy w which I had the stock rom with gingerbread.
I was searching for a custom rom for the phone and saw that there were cm9 cm10 and cm11.
I installed the new cm11 by arco68 but I'm having problems with the battery with greenify already installed.
During the night when I was asleep in 3 hours used 10% of my battery.
I'm new in roms and android development, so can anyone help me and tell me the differences between each cm version?
Any version is more lighter with the battery?
What can I do improve the battery use?
Thanks in advance
Try CM9

Apparently Google claimed that 4.4 KitKat is designed for low-end phones. So use CM11
Smack that Thanks button if I helped!

P.S. Time for school, not much time for XDA
for me its cm9 or cm11
For me now the best battery saving ROM + kernel is CM 9 and hurtsky's kernel, it is just awesome, if you need battery then this is the right combination for you
CyanogenMod 9 + Hurtsky's Kernel.

I installed CM11 and it worked, but The device was warm and battery drained fast, I installed it again with following tuterials and format sdcard0 this time, it get better but the main problem is to install/flash another kernel or update like khan kernel or philz touch, they are failed with status 7 ,
I tried to removed assert line from updater_script but it didn't work, It seems the os is now heavier than these works and I am confused right now,
please help me :
1- what to do first, should I install CM11 from scratch ?
2- for istalling khan kernel should I install Philz touch? and if so, what I should to do with the status 7 problem
I have installed CMR 6.0.4.5 and it works,
