Using Superkernel 2.0 = battery drain fast. Loss ~ 5% in one hour. Switched back to superkernel 1.1.

My set up is Stock ROM rooted with DoomLord + SuperKernel 1.1 +setcpu + JD = amazing battery life.

Replace same with Superkernel 2.0 , battery drain fast. So for my needs, its battery life, i go back to 1.1

Cheers

Yes see my post #1346 .
I am currently using stock rom with kernel 1.1.

I didn't have to try kernel 2.0 for too long to see battery drain fast in front of my eyes. Drop 5% in one hour doing nothing and 1% drop every few mins when using phone. But that's with stock rom.

So flashed back kernel 1.1 .I think there is many review here that kernel 1.1 is best for battery. I would recommend that too cause I have used it with stock rom ,juffo rom and super rom v 1. Its good kernel.

With using 2 push emails including company one which dumps 150 emails per day and moderate high usage with kernel 1.1. I can push more than a day on battery but it will vary from people to people I am sure.

@premk71 may i know how do u set ur juice defender?i've install juice defender but seems nothing change about the battery life

I've given a complete story in page 41, post #817.
I reproduce here again for u. Its complete with whatever I done for battery life. The link to JD is within. Nothing extra from me, I just used what's already known.

Now this is way out of topic of this thread, but I suppose, eventually one of reason people root to is get the better of their battery by freezing and stuff, so I try shed my little experience. Bad news, you have to read up a few threads , maybe 40 pages in all to really know what's happening.

And If u scare it will brick by flashing around, its tough. Sooner or later you need to cross that bridge to get some goodies.

But for better battery you can try this without flashing ROM.

1. Root your phone with Doomlord method. Its either work or dont work only, wont brick ur phone.
2. Once rooted , you'll have superuser app to grant root permissions.
3. Download & install titanium backup pro . You can google around. Sorry cant give u links to crackware. Better buy it but its your choice.
4. Download BetterBatteryStats ( BBS). There is a free version on xda.
5. Download Setcpu - you can buy it or get the xda version free.
6. Get yourself JuiceDefender / JuiceDefender Ultimate. ( JD)
7. Get yourself Autostarts (AS)

There are many threads on xda , some people say use BBS, dont use JD and setcpu and there is another group that swear JD/SetCPU is good. What I did is to combine all - and feel free to experiment on your own. This is not the only way you'll save battery.

1. Use TitaniumBackup to freeze all unused apps that come preinstalled. Check thru and see which one you really need. I have frozen Accuweather,Allshare,Android Live Wallpaper,APMobile,Books( if u have it),unused fonts,Days,Email 1.0,Email 3.0.0.1,GameHub,Homescreen Tips,IM,Kobo,Livewallpaper picker,Maps, MiniDiary, News, Oceanwether, OMACP, Readers Hub,Samsung Apps/UNA,Entire SNS,Social Hubs,streetview,Windyweather, yahoofinance,Zinio Reader. You choose what u really need , rest just freeze it. All of the above I dont need or have alternatives.

2,I turn off stuff in settings, accounts and sync, I turn off auto-sync, I turn off motion ( i dont need it), in Location/Security, I turn off "Use wireless network", in Privacy, I turn off "back up my data". Turn off auto brightness and anything else that may suck battery. There are tonnes of articles online search, fiddle and experiment.


3.Then I charged my phone and used BBS to see what is still keeping my phone "awake". Most times, its friendcaster app. I adjust the settings for friendcaster and other apps. Again, pls read thru BBS thread in xda.
http://forum.xda-developers.com/showthread.php?t=1179809 - you can read a few pages in front and back.

4.I use setcpu and apply profiles that cap the cpu when screen is off and when battery is getting low.
Read here for start http://forum.xda-developers.com/showthread.php?t=1158102

5.I used JD Ultimate and settings from forums. See here but feel free to research and experiment and understand what you are setting.
http://www.villainrom.co.uk/forum/showthre...ender-(Ultimate

6. Of the remaining apps that are not frozen, I use autostarts, to turn of "event triggered starts". I have a very lean startup and most apps run only when i click on them. they dont autostart as they were programmed to do. You can start with a few and experiment as you go along.


With rooted stock firmware, with light-moderate use, I can stretch my battery to about 32 hours. Gmails, Friendcaster checks maybe 10 times, music for ~20-30mins, some games (Angry Birds) , watch a few song video, many many SMS, a few calls, and check this forum online maybe 20 times. Also sync my office email with Roadsync 3-4 times manually. JD "claims" it has helped increase my battery about 1.8x. But 32 hours is not repeatable many times. Occassionally I get 24 hours,26 hours, 22 hours. Even with Juffo 2.1 is about the same.

Now I am rubbing my hands with glee since its mentioned that superatmos has tweaked power management. I really wanna see how long the battery lasts. So the above is my small experience . I been using android only ~ 2 months now. My biggest shock migrating from my Nokia N8 to SGS2 is battery life. Otherwise no complaints.

I think u are using SuperRom? Superatmos has given on his first page for his ROM, one ICS theme rebuild based on vertumus. You can use that without harm. Many of us have tried that. if u download direct from vertumus for theme not optimized for I9100g u get bootloops and what not.

-------------------------------------------------
of course on stock rom u'd see bootloops too . So if u wanna get that vertumus look, go for SuperRom. From my experience, kernel 1.1 + SuperRom v 1 is fantastic! and u flash over a ICS theme given by superatmos

maybe u can try clear cache and dalvik cache before/after install universal version and see. Otherwise, tough luck.
In past I have taken some elements of such universal theme and used but I dont think the whole theme can be used on stock rom, - reference odex/deodex. But I could be wrong.

And then there are some themes that dont say Universal but simply "ALL TW ROMS", i've had better luck with those. Try clear cache and see.
All the best.

the one from superatmos for superROM is more complete theming with every part including keyboard is ICS themed. I tried the above link, didnt like it, some notification boxes didnt display properly ( maybe my font is too big), went back to original.

When the real ICS comes, that'll be good. Did play around with friend's Samsung Nexus, not bad. Waiting for ICS on SII.

Besides that nothing much happening here on this front.. same old questions about rooting , unbrick, battery.

Same old threads man. In all the same old forums. So bored ready. Time to get a new hobby or a new device.

Guess u are using custom rom? I suppose u can't even update thru kies ? I believe the csc is set to be gbe or kor (Great Britain or Korea) by default in custom rom. U need the +#272*imei# to reselect xme but it will reformat ur phone back.

Every time reinstall firmware thru Odin(even stock dzkj2) or custom rom I check whether its xme before restore apps and stuff.

Also I forgot which one but there is custom rom can't update OTA. I think those components been removed or rearranged

to get back stock kernel, just flash stock DZKJ2. Kernel is within. I dont know why anyone would want to use custom ROM but with the kernel only reflash back to stock. Hence I think u need to do as i said.

However, if u insist on flashing stock kernel from DZKJ2 firmware onto your phone ( whether its running stock or custom rom), dont try to extract the Zimage from the *.tar and use ODIN. You'd have to know how to re-tar it and etc. Otherwise, flashing ODIN will hang halfway and u end up soft brick.

the easier way is to

1. root your phone
2. Install K-tool from market
3. Extract the Zimage from stock firmware *.tar file. if u cannot, get some one who is already stock+ rooted and have K tool on their phone. They can use "K tool" to dump their kernel onto their SD card and pass to you.
4. Move the Zimage to SD card of ur phone. Open K-tool and flash from SD card.

Done . U have stock kernel back. The above is useful for folks who wanna try a few different kernels. But make sure the kernel come for which phone model.

i using stock ROM with superkernel 1.1. I used framework-res.apk from SuperRom V 2.0 so I have the battery indicator like that ROM.
Quite bored to try custom ROMs, each one got pro and con. some are missing some component or some of the deoxed stuff dont function properly.. too long story.. so back to stock ROM.

My main focus is battery life. Rest comes second.

The .md5 u can extract using 7z archiver. The Zimage u get is not rooted.Not sure if this can be used. What I have always done is root my stock DZKJ2 and get the Zimage dumped from K tool to re-flash when needed. U can try above. I'd see if u can upload somewhere stock dzkj2 with root kernel.

------------------------------------
H3llboy, see ur PM

----------------------------------------
separate note: guys try anything at your own risk. galaxy s11 is hard to completely brick, but, hey you never know. I have had so many soft bricks trying stuff. dont panic. have standby the pit and stock dzkj2 firmware always.worse case i have been able to use odin to flash back to stock when soft brick

Try all ready... super ROM 1, 1.1, 2.0, Juffo 1,2,2.1 everything.
Superkernel is superatmos. I see the v 1.1 is best for battery as governor by default is power save.
Now i upgrading to new firmware, lets see whats so good about it.

Version 1.2 supports

This new firmware KL3 is a piece of @#@(!((@....( use ur imagination).

1. Cant root. The exploit with doomlord been covered.Even use doomlord v4, cannot

2. Battery life isnt that great, maybe slightly better than DZKJ2 stock and sure loose to superkernel 1.1. Since cannot root, cannot install setcpu too.

3.I flashed custom kernel superkernel 1.1 - have yellow triangle and binary counter go up

4.If use USB jig , no impact, yellow triangle and binary count still there , in my case , binary counter=1.

5. If u used USB jig and then restarted phone, all the homescreen icons go missing and cannot access applications. Need to get into recovery and clear all caches and reboot phone.

6.Since cannot remove yellow triangle and custom binary count, but already got root from superkernel 1.1, I install K-Tool and dump Zimage from superkernel 1.1 to sd card. Then I used ODIN to flash stock kernel from DZKI1 ( page 1).

7.Yellow triangle disappear but custom binary count remain =1.

8. Then used K tool to reflash superkernel 1.1 Zimage from SD card to enjoy the powersaving benefit of superkernel 1.1

9.Binary count still =1, if use USB jig again, number # 5 above happens.

10.So downgrade to DZKJ2, put in the pit file and stock DZKJ2 firmware from page 1 and flash using ODIN.

11.Success but still custom binary count =1.

12. Use USB jig, custom binary count =zero, erased and back to fully stock DZKJ2 but had to do a data wipe/factory reset first since all icons missing from home screen as per # 5( i donno why still happen after downgrade)

So now going to root with DoomLord and get back to normalcy. I am not going to bother with KL3 unless someone finds a way to root without yellow triangle and custom binary go up. Not much other change except the dialer icon looked a bit different.

3 months with I9100g is way too long with all these stuff. If i get the offer tomorrow, it might be the last day of my S2, maybe , maybe not. We'll see. We'll see.Even ICS, if its rootable , then its worth it in my opinion. Really without rooting a lot of battery saving stuff is lost. I cant understand the rationale of buying a slim phone but piss poor battery and need to carry charger or spare battery or extended bulky battery.

wierd part....doomlord couldnt root after downgrade even with memory crash method. tried 4 times. got fed up and just used the custom kernel flash with ODIN and use USB jig to settle the custom binary .Custom binary disappear but had to reformat the phone to factory settings because of # 5.

Wierd, i thought that downgrade back can use doomlord, or maybe its one of those days...... with doomlord

Yeap as i said....failure to root with doomlord could be due to "one of those days".... sometimes need a few try... i am sure it works on DZKJ2, need probably to pump up RAM usage to 600mb plus to give allowance to auto close apps

Added on January 13, 2012, 4:44 amBro, quesstion
insecure kernel is already rooted, right? so why use superclick on it?
what's ur custom binary count now and the stock Zimage is it from KL3?

Turn off your phone. Get into download mode by 3 button technique. Volume Down+Home+Power.( do in this sequence) Dont let go any button, once u get the instruction to continue, slide ur finger from volume down button to volume up. WIll get u into download mode. Try a few times if you are butter fingers or phone just restarts without getting into download mode.

Then download pit file and stock DZKJ2 from page 1. Read first post in page one. Select the pit file and select the firmware by clicking "PDA" button on ODIN. Connect ur phone and flash.

It all depends on getting ur phone into download mode. That's all. If really cannot get ur phone into download, then sorry, out of luck, but u should be able to. Dont forget the pit file.

It happens .S&@* happens. Nothing to feel cheated about. Both version have its ups and downs.
Good Luck.

Ha Ha Ha...... so true... sometimes its so painful to come in and read .... haiyo.Feel like shooting some of the questions man.....if they read your guide pun cukup daaa.... anyway good to see u back.
For the rest of the folks, search before question.

Added on January 21, 2012, 1:31 amYes, thats the way to fix it. If u fail flash, or u sometimes flash the wrong file, or if try to just extract Zimage from stock rom and dont repack it properly with the correct tool and reflash , etc etc etc, u'd end up in semi brick state. Phone and PC logo with a disconnected sign on ur phone screen.

Flash back stock ROM. I usually put in the pit file in too. Dont worry done it 30-40 times. Keep the stock ROM files/pit handy.

Yes, to go back to unroot state just flash stock firmware with ODIN.No it will not increase ur counts, its stock. See page 1 for complete instructions or read the guide from creezalird.

U can use the unroot script only if u have used doomlord method. I have unroot my tab before.

Btw, why do u need to unroot ur phone for ICS in future?
