Thank you please do come back and share your results.

Much appreciated, please do come back and share your results.

I am glad to read this dramatic change in your battery.

Perhaps you set Tapatalk 'Auto Config' at Gemini app to OFF, this is a good example of an app you DON'T put on off mode since you have options in the app to turn on notifications and alert the user about things thus, it goes into 'Auto commands' groups that you mustn't turn things off.

I really don't see a connection to LBE since it only responsible to inet connection and other permissions, in other words it CAN'T be responsible for FC.
[Galaxy S II General] rwanek:
Thanks! I restored all settings in Gemini but it didnt help, cleared data and still no Go. So uninstalled, reboot and installed one more time, restored data from titanium and its working! :)

[Galaxy S II General] hyperbolic:
Glad to read that it worked for you.

It seems to be non-related to my guide.
[Galaxy S II General] mlkyc9:
Now this is amazing and I must show it to you. Sorry, I forgot to dump .txt file before I plugged my phone in.

Phone: SGS2 (GT-I9100)
[Galaxy S II General] hyperbolic:
I don't have the dump file to take a closer look BUT, it seems that you followed the guide and most of his steps, these "drains" are completely normal.

Good job and I glad you like the guide.

EDIT:

Btw, You can minimize the 'Audioout' by unticking: 'System settings -> Sound' , under System, untick them all.

Plus, in the same window click on "Vibration intensity' and put 'Vibrate on screen tap' on the lowest (0).

I will add this to the guide too.
[Galaxy S II General] bulldozer1021:
thanks for the good tips!

i used some tips but others new information for me :laugh:
[Galaxy S II General] sk1887:
Nice tips man. I will try them out now for JB!

There is not really much need of Titanium Backup when you are root and knowledgeable about it.

Freeze can be done without purchasing TB, in the Apps section and use Disable.

I think you can simply browse /system/app and delete those you do not need and follow the link, freeze is not really necessary don't you think?

I'm currently trying the -50mV undervolting. I usually use the phone for whatsapp and browsing. I often had great results with Siyah's battery profile, but I know it's not enough :P

However I want to see the performance when I use bs player.. let' see!
[Galaxy S II General] dexvholt:
A LOT OF APPS to have nearly as good results as Dorimanx Kernel, guys just install Dorimanx Kernel and run it in defaut profile NO NEED to tweak and you'll have even better results .. here is the thread read people's comments and see by yourselves : http://xdaforums.com/showthread.php?t=1617219
[Galaxy S II General] hyperbolic:
Great, come back and share your results.

Glad you like the guide.

You are correct, you don't have to install TB you can do as you mentioned, but freezing gives you the ability to restore WITH your personal data.

Did you undervolt via ExTweaks, -50mV to all frequencies ? this method is less aggressive as I wrote, you could get better results with the aggressive one.

Obviously you didn't read the guide thoroughly, only a step or two.

Dorimax kernel is based on Siyah kernel, I didn't try this kernel though it looks almost the same as Siyah.

Dorimax kernel doesn't do the things I mention in the guide, after all it's a kernel.

After a while with your phone there are apps/games that could wake your device regardless which kernel you use, if you have an app that will wake your device it will be awaken thus I included in the guide the explanation and importance of setting off Auto apps you don't need.

Also, I explained how to tell if there is a wakelock and how to deal with it, a common user doesn't understand what it is and how to deal with it.

I can keep on writing and explaining each step of the guide (regarding your statement), why it's not included in the kernel you mentioned (or any kernel) and why every user need to be responsible for his own device by these steps and getting better battery experience.
[Galaxy S II General] Duplexity:
Hey, looks like a very detailed and well written guide.

I was about to do the settings but wondered what you thought about the performance of the phone upon doing the tweaks.

Did it slow down or anything in terms of performance?

Sorry I have to ask this question but I don't really know any of the options, I was just about to blindly apply them lol.

Thanks!

how to enable ARCH_POWER = On?

extweak doesnt have this option on CPU tab.

Im using Siyah 4.1.4
[Galaxy S II General] ii7Stryker:
It is present under Gentle_fair_sleepers.

Nice guide :D .

Btw I am using Rom Toolbox instead of SetCPU and Gemini. The autorun of RTB is better than the gemini one -more detailed- .
[Galaxy S II General] hyperbolic:
Thank you glad you like it.

That is a good question,

Regarding the UI you might feel a little lag (if you were using stock frequencies and voltages) or you might not feel any lag (depends on your launcher), If you install Nova launcher and use it instead of the TW you won't feel any lag since the Nova launcher is code efficient.

Regarding the apps, you won't feel any lag unless it's a graphic app or design/CAD app (even this is questionable).

Regarding the games, you won't feel any lag in most of the games, I played a lot of games for example Dead Trigger/Galaxy on fire 2/Shadowgun/Samuraio II and few more, I didn't feel any lag or what so ever, though I did feel that the loading steps took 1-2 more minutes.

It's not a tab it is sub tab under Gentle_fair_sleepers like 'ii7Stryker' wrote to you.

It should be on as default if you don't see it you must be using a very old version of ExTweaks.

Thank you glad you like it.

This app looks really good and efficient, I read about it few weeks ago I will give it a try soon and maybe I will recommend this app in my guide.

Help

its not present on CPU tab. Only Gentle_fair_sleepers.

---------- Post added at 08:37 PM ---------- Previous post was at 08:31 PM ----------

Im using the 0.20 version of xtweaks.. Yes, in CPU tab there is a sub tab and only Gentle_fair_sleepers is available and nothing follows. So i only tick Gentle_fair_sleepers. I was wondering how to enable POWER ARCH. thats why i ask how to make it ON in extweaks even if it is not available on CPU Tab. thanks
[Galaxy S II General] Duplexity:
Thanks for your quick reply.

Luckily Nova is my favourite launcher and I bought prime when it was so cheap the other day...so, I'll apply everything today and tell you how it goes!

Edit: Found answer.
[Galaxy S II General] randomseasons:
@Hyperbolic: First thing I want to say is that I know you're a maniac, and I know you were telling the truth about your 1000 pages, yes because I personally read 500 pages of tweaks too and I really came close to the idea of creating a similiar thread like this.

- About the tweaks, I found we are using very different methods, yet I also achieve a very high result like you (nearly the same), so here are my methods:

***I'm using GB (this doesn't matter, simply 'cause i find it perfect for my demand so I don't need to upgrade to ICS or JB), siyah 2.6.14 (I'm turning back to 2.6.13 because the users said it was better)

- Voltage Control: I found my own lowest voltage (not the painful method you said but I believe it is extremely good now)

- Extweaks: I TURN OFF 2nd core, yes this is personal, I don't play HD games or benchmarking, and it turns out to be SMOOTHER using one core for casual tasks, yes it is, I suggest you try if you are a normal user like me. With one core, the tweaks are much easier for the CPU. With GPU, I have only 2 steps: 133Mhz and 200 MHz, below 133MHz I notice lags and above 200 I don't notice any improvement.

- Lulzactive control: yes I'm using Lulzactive, and by countless adjustment, I'm having a state which is a "stair-shape", I mean in CPUstats it shows the most used frequency is 200mhz, the 2nd most used is 500Mhz and up up..

- Remove bloatware: I spent 2 hours to investigate the Samsung app lists, and I removed all, not froze them.

- I found an app called "autostats" which allows me to disable all the unneccessary apps after start-up.

- A lot of widgets but NONE on the main home screen, only icons.

- Using manual brightness in-door and auto-brightness out-door.

- Checkrom Revo HD v6 ( don't know if this is relevant)

- Disable Fast Dormancy and Restrict to only 3G (No HSUPDA, this is also personal as the speed here sucks, H+ is a waste of battery)

- Many other small things and battery-friendly habits during daily use.

- If OP is interested, we may cooperate to test new methods, I believe OP's method is extreme but there's one better somewhere :fingers-crossed:

P/s: sorry for my English
[Galaxy S II General] Duplexity:
I finished applying all of the customizations and my battery is so amazing right now.

I had 3% drain overnight and very minimal wakelocks.

To be honest though I did not go through steps 1-2, after going from 3-9 it pretty much....increased my battery life substantially.

So far I am at 87% with 12 hours of uptime.

I'd really recommend people who haven't tried it yet to give it a go!

[Galaxy S II General] hyperbolic:
Dorimax kernel is based on Siyah kernel.

This guide is the same for every kernel that support undervolting.

Siyah kernel also support ExTweaks app, if dorimax doesn't support this app just skip step 4, besides that you can do

all the steps

Good luck and after you're done come back and share your results.

battery help

Hello

I've been having some battery problems with my sgs2. I've bought it in june of 2011, it is my first smartphone and I was immediately pleased with it. great phone, everything working properly. since it was my first phone I was a light user and the battery could last me 2 days, sometimes it even got to last 3 days. However, at the beginning of the year I felt a sudden drop in battery performance, coming to last only 12-15 hours with light use. by this time I became more of a medium-heavy user and under "normal" use the phone would be dead at 10 hours, maximum.

I bought a new battery, official samsung 2000 mAh, and the performance became slightly better. It would at least last a day of work, but the performance was never as good as the original 1650 mAh battery when I first bought the phone.

by this time I began experimenting with ROMs, ressurection remix, miui, and now pfittech. but as time passes the performance is always dropping and today something strange happened. I locked my phone at 17% of battery, and after a while I checked it and the battery was at 18%. I checked again and is now at 19%. What the hell?

can anyone help me? any help would be much appreciated.

p.s. i've tried calibrating the battery and I've read in the forums that on JB it's not necessary because the phone now clears battery stats when they reach 100%. I've also changed the stats with extweaks to absolutely no effect. I've been reading many topics on this but nothing quite seems to fit my situation.
[Galaxy S II General] mananbdesai:

Thanks for the guide. Found some useful tips there.
[Galaxy S II General] Donnie Sins:
Found some usefull tips too. However, heavy gaming (Modern Combat II) didn't work quite well for me, some freezes and laggy graphics, which isn't that weird because of the UV and UC, but it didn't work either when clocked at 1200mHz... (when I actually did follow the rest of the guide and the voltages)

Sent from the Matrix
[Galaxy S II General] hyperbolic:
Glad you like the guide please come back and share your improvements.

Regarding Modern Combat II, I believe you when you say it's a little laggy, but it can't freeze.

I am playing games that their need for faster cpu/gpu is higher than Modern Combat II and they have never froze on me, though some lags are noticeable and then I just set 200-1200mhz.

Thank you all.

Please come back and share your results and improvements with us.
[Galaxy S II General] Donnie Sins:
I tried again, with Voltage Control as a second app, and I noticed I had -25mV in Extweaks, on top of the voltages of Voltage Control, so you were right, because now it doesn't freeze anymore because I removed the -25mV (my mistake).

Especially the tip of Gemini worked out very well for me;)

Tnx!

[Galaxy S II General] Obagleyfreer:
Just thought I'd share something I do so I don't have to use the Facebook app which is a HUGE battery drain.

I simply logged onto the Facebook Mobile site and when I was on the homepage I saved it as a bookmark. Then added the bookmark to my home screen as the Facebook icon. It looks exactly the same as Facebook app icon but when pressed it simply loads up the home page on the mobile site instead of the app.

In my opinion this is much better anyway as the app is buggy and slow.

Undervolting is individually to every ROM & kernel combination, so recommending your voltages could be good for someone even though he could undervolt

I decided to delete secphone.apk as it was always running in the background but when I did I had deep sleep issues. I reinstalled it and now everything is fine again...... Any ideas?
[Galaxy S II General] bobdoblo:
I have also deleted this today but cannot find out what it does, i know on s3 it is call recording but not on s2!

I know others that have deleted it and have no trouble with deep sleep and just did a quick test on mine, left it alone for a bit and it went to deep sleep no problem, i have a feeling it might be to do with 2g and 3g switch?

Back in the days when I wanted to know what is Secphone.apk, no one knew what it is except that if you use TouchWiz as your launcher

DON'T

remove it and I even wrote it in the guide as followed:

Of course if you guys are still using TouchWiz I am afraid you are losing 4-5% battery every cycle because TouchWiz isn't code efficient.

I also wrote about this in the FAQ:

So please, follow the guide and all the steps thoroughly because if you freeze Secphone.apk and your using TouchWiz obviously you are skipping steps, or you're an idiot.

Apps not installing/uninstalling

Hey thanks for this awesome guide you posted.

but somehow after performing Gemini App Manager Step, I am unable to install/uninstall any app.

Also, I have not touched any system app or tried to stop it via Gemini.

It seems there's a problem in Package Installer but I am unable to figure it out how to fix this issue.

Cleared cache, Davlik Cache, Fixed Permissions also.

PS: clear cache in app manager is not highlighted in any app :(
[Galaxy S II General] hyperbolic:
Thank you for your feedback.

1. Please state your ROM and Kernel.

2. Did you follow each step and followed Gemini step exactly as it says ?

3. You can always contact Gemini app developer for support since it is as you wrote, a problem in the package installer, or you can try to uninstall and install it again.

Hi thanks for your work. I ve a problem. When i finish to use the gemini app to disable auto run my phone freezes and when i reset its freez too. Second time i have to wipe... This time i was careful not to touch any system app only some rom aps that i dont use. Can i only disable auto run for apps that i have instaled??
[Galaxy S II General] hyperbolic:
You shouldn't touch most of the system apps or something you don't familiar with.

As I wrote in the guide:

How to tell if you can turn off or not in an app/game:

Basically the idea is this,

If we are talking about an app that the whole very existence is to do things by it self (Playing songs/Setting alarms/Auto-commands apps) then of course we won't turn anything off.

If we are talking about a type of apps that their whole process is to do something particularly which will take place only when we open the app (Bar-code scanner/Weather app/Shazam/Office apps/GPS apps/Games so of course we will turn everything off.

If we are talking about ROOT apps so I suggest not to touch anything

.
[Galaxy S II General] Triplehm:
Thanks i think that was becouse i was trying to disable some preinstaled apps. Now everything i fine, and im testing new settings:) At first i didnt understand you. I thought root apps are system apps, but now i know that alsaw every app that is in rom shouldent by touched.

Today I was sick and I decided the spend the day testing the phone. This configuration is great for battery life and stable

For cpu

1200000 1175

1100000 1125

1000000 1075

900000 1025

800000 975

700000 950

600000 950

500000 950

400000 900

300000 850

200000 825

100000 800

According to the tests I've done 86% of the time, cpu is below 600MHz state. Also I've decided to insert the 100mhz. It works great without any problems and we can save up a bunch of juice, near - 150mv.

Would recommend you guys leave the 500mhz till 800MHz as is. Or it'll freeze the phone.

Any thoughts? Wanna know your opinion.

The Gpu cannot be undervolted the limit is 1000mv for 200mhz and 267mhz.

160mhz I would love to test with 925mv

100MHz is 900mv

64mhz us 850mv

The only thing we can do to make sure it'll conserve battery is to raise the percentage before he raises frequency. I've decided to make near 85% to raise and 75% to decrease with 5 steps. Seems to be A OK. :)

Thank you for your feedback, please come back and share your results and your opinions.

Looks great.

Please consider that undervolting is individual for every user thus your undervolt isn't the same as mine or anyone.

If you want to save more juice try to focus on wakelocks and other parts of the guide because it seems you have reached the limit of undervolting.

When I will have free time I will test 100mhz as minimum freq, I have never tried it since I heard ppl experiencing many freezes.

Guys, i'm using gsam battery monitor to analise my battery consumption and I saw some huge apps drain during my battery circle. The Gsam shows that the kernel and android system are responsible for almost 60% of my battery usage. Even more that the screen, who only takes 18% of my battery. I've done all the tweaks suggested by this thread, all the battery save recommendations, and the kernel and android system are still draining the most part of my battery. This doesn't make sense for me. Is that something that's supposed to happen? I have sgs2 with cm10 and siyah kernel

Thanks for all help
[Galaxy S II General] Kitschki:
I dont understand why kernel has a high drain but i think that android system always had a high battery drain
[Galaxy S II General] hyperbolic:
If you could provide a log via BBS I could analyze your situation.

The way I see it is that you almost never use your phone thus the screen time percentage is low, so of course 'Android' and 'kernel' will gain the highest percentage.

Bottom line it seems you followed the guide and only essential operations are running such as 'Android' and 'kernel'.
[Galaxy S II General] zubsz:
Another kernel?

would it be possible to use the guide for dorimanx kernel since it is a variation of the kernel?

i used this guide when i had the siyah kernel and the results were unbelievably so would this guide work for dorimanx kernel as well?

thanks :D
