I am using an hd2, and i have noticed something that may be causing a lot of battery drain, that is consistent among every build that I have used. When I use setcpu, and give it root access, and whether i select auto detect or manually put in nexus one/snap dragon, it does not listen to the cpu cap that i put. i will exit the app, and go back to it, and the cpu clock speed with almost always exceed the cpu cap that i set, and many times, it will be running at the full 998 mhz. why is this, and how can i fix it?
I uninstalled SetCPU the other day as a little experiment. It makes f-all difference to me. In fact it makes things worse.
no longer needed with the latest kernels

This problem seems to relate to a kernel feature called perflock .. disabling this in-kernel allows the cpu cap in setcpu to be adhered to .. Unfortunately this is done at compile time and has no userland interface to use. I dont think its relating to all the battery drain you see but for sure if you limit cpu speeds with profiles like screen off it will have an effect.
try updateing super user libraries.

Whats that then ?
how would i go about updating the su libraries? does anybody have an actual fix to this, because i would think my battery would be a lot better if the set cpu app was actaully working. and no, the latest kernels dont seem to be doing their job, because they all burn through juice like theres no tomorrow.
u have 2.04 installed ? it fc'd for me , now im using 2.02 no problems , try that

You don't update the su libraries .. su is either a static file or a link to busybox .. i cba looking right now .. probably a binary compiled statically ..
To have your issue resolved have a word with your friendly neighborhood kernel builder and ask him to disable perflock .. Its not needed for normal operation.
I'm having the same problem. Does anyone know how to get setcpu to work?! I have an HD2 running darkstone Froyo.
Hi everyone.
Id like to start a thread where we collect, post and discuss all known individual tweaks and changes that can be made to the Galaxy Tab in order to gain performance and stability.
My experience with the Galaxy Tab has been similar to my latest phone, an HTC HD2. When I got the HD2 about one year ago, I positively hated it... slow, unstable, all sorts of problems, lags, crashes... its the way most of the hardware today is released. One year later, my HD2 has become the most amazing machine I've ever owned. From pushing it 1.6GHz stable, to tweaking registry, XML files, services and making everything work well. I remember not being able to watch smooth video on the HD2 to being able to watch flawlessly 720p content and going from the extreme of detesting the phone to loving it.
It was with the HD2 I discovered Android and fell in love with it. Since I have now two HD2s I have one with an SD ROM version of Gingerbread (that I can dual boot still from Windows Mobile) and a Froyo NAND. I run Android on the HD2 much much much faster and smoother than on the Galaxy Tab, that I also hated when I bought it a few weeks and that am starting to like after getting to know it, a new ROM, apps, etc. Even at 1GHz stock the HD2 with Froyo is vastly faster, smoother, more responsive and better to use. The approach d like to do as far as tweaking the Galaxy Tab is the same as I did for the HD2 with Windows Mobile, that is, install the best/fastest ROM I can, delete and remove all stuff I don't need and then tweak what's left.
The tweaks I've done so far on the Galaxy are simple but have made a huge difference. Id like with this thread to be able to collect individual tweaks and post them all here to share with everyone.
Im using Roto JMI Pre-Rooted Firmware v2 which was the main step after getting rid of the stock Samsung Rom that is nothing but a collection of problems.
The first thing I learned with this Tab is that WHATEVER IS ON YOUR HOME SCREENS THAT MOVES, IS BAD! Forget about having ANY type of apps or widgets that do any type of refresh, including stuff running on the upper task bar if they change icons or the move around… that mean a CPU cycle and refresh each time and there goes the tab's performance and battery life. The same goes for any type of Live Wallpaper. Beautiful but deadly. Never touch them!
- So, after a new ROM, the first thing I did was changing the file system to EXT4. This is the SINGLE BEST THING you can do to radically improve the performance of the Tab. Its extremely easy to do and the step-by-step instructions are as follow:
- Make sure you have an miniSD Card in with plenty of available space (it will be used automatically to backup your system during the conversion process)
- Get p1000-mck-r3-ext4-cwm.tar (the EXT4 Conversion Kernel)
- Connect the Tab in Downloading Mode to your PC via USB, start Odin3 1.7 and load the Kernel (click on the PDA button and select the p1000-mck-r3-ext4-cwm.tar and make sure PDA stays ticked after selecting the file).
- UNTICK Re-Partition check box and make sure the only boxes ticked are:
Auto Reboot
F. Reset Time
The PDA tickbox
- Click start and wait for PASS! (it will show highlighted green or Yellow on Odin)
- Now the Tab will restart and get stuck on the Samsung loading screen. This is normal. Turn it off by holding the power button for 5 seconds.
- Turn on the Tab again on into RECOVERY mode (Press Volume UP and Power On at the same time) and the EXT4 conversion will start automatically. The process will take up to one hour depending on how much stuff you have on your Tab. It took about 10 minutes on mine because I have a fresh install of Roto JMI v2.
- Once finished, click "Reboot System Now" (by pressing the power button).
- The reboot may take a while first time so be patient!
- Done!
- After that, the first tweak I did was to get rid of all my favorite widgets that moved around… net meter, news, weather and all these beautiful things KILL the Tab. Equally I had a CPU meter on the tray refreshing every 2 seconds and it took me a while to figure out that was the reason why every 2 seconds the system would stutter, whether watching a movie or browsing the web. So, out!
- Next was to install SetCPU under the ON DEMAND setting, minimum around 750MHz and maximum 1000MHz (unfortunately only with a custom Kernel you can go higher, currently up to 1.4GHz but not full stable and with lots of issues pending so I don’t recommend it)
- My following step was to get rid of the stock Samsung Homescreen (that is a resource hog and slow as hell) and replace it with a new one. I've tried them all and am making no recommendation here but the one that works for me and is by far the best IMO is LauncherPro. This single app makes using the Tab a whole better experience.
- Next was to disable the USELESS and (resource pig) Gallery and replace it with an app called QuickPic that is blazing fast (actually instant) and simply amazing to browse and view all media on the Tab.
- Next was to greatly improve the poor native GPS reception by replacing high performance files and drivers from the Orange Rom P1000JHKA1 that seems to work on all versions of the Tab, as originally posted here:
http://forum.xda-developers.com/showthread.php?t=922692
- With SystemApp Remover 4.12 I have disabled all system apps and services I don’t need (BE VERY CAREFUL AND DON'T REMOVE ROM APPS YOU WILL NEED). I have actually deleted some from ROM (Root access required of course), this includes useless stuff like STK Service starting every time, most of the Samsung stuff that I really don’t care for and just about all apps I know for sure I will never open a single time. Now, its important to understand if these apps are removed they will be removed PERMANENTLY from ROM so to get the back a hard reset will not be enough, you'll have to fully flash the ROM again. For most system apps I don’t use but am not sure, I use a different option and that is to simply disable them. In my case this includes all Bluetooth stuff (I never use it and even if it's off the Services are still running robbing performance and memory) and apps like the built-in Browser, Email and Messaging that suck and that I replaced with better apps. Its always a safer bet, at least initially to disable the apps you don’t need that uninstall them because at least you can go back and change your mind This is one area where Id like to learn more. There are many background services that I don’t know what they do and if they can be disabled or not. If someone knows what each one does and the safety of getting rid of them OR NOT, it would be great to post it here!
- Them, with Startup Auditor 2.3.2 I have disabled all unnecessary apps that start automatically every time the Tab boots so I don't have excess applications starting up that are not needed. Some I configured to be killed AGAIN if the system tries to restart them later after the boot-up
- Using Task Manager 1.0.7 and letting always run on background, I have configured all apps that I don’t need running to be auto-killed every time the phone goes to stand-by (screen off). This saves me lots of memory and CPU time on apps that I am actually not using.
- Finally, I monitor what is going on with an app called CPU Usage Timeliness Free 1.7.1.0 and use it to see EXACTLY which applications are using CPU cycles and interfering with performance. With it I have found that on my Tab I have an unsolved problem that is using over 100MB of memory and non-stop CPU usage between 15% and 45% of something called SECURITY STORAGE. I have no idea what it does. It can't be disabled and I don’t know where all the activity comes from. If someone know more about this and how to fix it, that will be great. Most of the performance issues I have on my Tab come from this Service that I don’t know how to tame. Surely, we can find a solution.
The system background services is one area where I'd like to know one by one, what each service does and if we need them or not, if it can be tweaked, disabled or deleted. Below is a complete list of the services I have safely disabled so far that have given me great performance boosts and with no negative issues on the system (IN BOLD), and OTHERS I WOULD LIKE TO KNOW MORE ABOUT (not bold). Please note these are background services that start automatically. The changes made to the disabled apps/services is that they are reverted to ON-DEMAND so they all still work perfectly.

Originally with my Tab I was getting Quadrant below 600 on average. Now, its always over 1900. This is not a "little" improvement, this is amazing upgrading. But id like this to be a starting point to learn and share more ways with everyone we can all share on things we can do to make the Tab as good as it was intended to be for everyone
Cheers!
1.4 oc is stable, and doesn't have any issues for alot of users.
all the things you disabled are all the things i use every day lol
never the less, good post, im going to use a couple apps you mentioned.

The first block of disabled items (in bold) from CALENDAR to WORLD CLOCK are disabled start-ups but the apps works as usual. It just frees resources not required on boot till you actually start the application when you want.
The second block from Bluetooth Services to Voice Search are all disabled as I use none of those. Items disabled can be restarted again at any time upon activating them follwing a reboot, while items deleted (like Samsung Apps and STK) are gone forever.
Ive never flashed a ModaCo Kernel and got lots of feedback regarding probelms with 1.4OC. Do you have any issues at all or none? We are using different ROMs... What Quadrant do you get currently?
Cheers
Thank you for your post.
You have solved many of my questions. Also I am User of HD2 and had the same impressions, but now with Android Nand everything was great, also started to love it.
As for GTAB'll make those adjustments you suggested, some will not disable because I use Bluetooth as an example.
Any news please keep posting.
Success!

So far the oc is good, things load a little faster, especially nfs shift. Last run of quadrant was 2300-2400.
Ill try it again later after these optimizations and see how it goes, a member here has gotten 3000.
Having done nothing but root, my tab gets about 1000 quadrant score. I have tried setcpu using on demand and it actuall has made my tab worse. I am very hesitant to flash anything on the tab. It seems very involved and complicated. I have an HD2 as well and have been flashing since Android was on SD. That process is simple. Everything I have read about flashing things to the tab doesn't look that way. I really havent had any issues with my tab as stock other than a bit laggy at times. I would like to hear more about all of this. The oppinions I have read are either do it or don't do it. There are more problem posts after attempting to flash than there are good ones where it worked. I really could care less about a quadrant score to be honest, but I would like to have a faster smoother running tab. I really dont care about making calls on it either. Thats why I have a phone. JMO. I think part of the issue in this thread is that there are Euro and USA version which are completely different and require different roms and such.
I have been reading and lurking in the tab development thread for a while now and am not impressed with any of it yet. Maybe someone could shed some light on things and change my mind.

I agree. The process of flashing the Galaxy is much more dauting than anything on the HD2. I suggest you do the EXT4 file converstion. All you need is follow the step by step I wrote above. It makes a huge difference. As for everything else, I too hold off to do too much flashing. The ROM I use now is great and lighter than stock but your seems to work well so keep it. For me when a ROM is good I just use it. When I bought the HD2 I flashed it 2 times with a custom ROM till i found one that worked for me and kept it for 8 months. But backing up and restoring WinMo is much easier... on Androind its all more complicated if you dont know what you are doing. Disable some start-ups on your unit, convert the file system to EXT4 and make sure you have nothing on your home screen doing a lot of refreshing and your tab will work great

Is everything working 100% on that ROM? I do not want any ROMS that are having problems.
I too am not impressed with anything that us out yet...seems like any ROM process is tedious and complicated.
Glad the thread starter modified his tab to his liking, but what's the point of having it if you need to drastically change everything. I have a rooted DInc and not use any of things......didn't really see a performance gain with set CPU.
I'm going to continue waiting for something more reliable and use my tab the way it was meant to be, with all its hardware and widgets.

Thank you for your detailed post. While I agree with you that the stock SGT rom and browser suck but where do you think the JMI, JMF, JMx ROMs coming from?
Most ROMs I've seen (except for CM) are based from some sort of Jxx
Please keep the tweak posts going. Good stuff and thanks!

My boy,
Only getting my Galaxy tomorrow but looking through threads on my favorite forum.
And guess the first one I happen into... I will follow avidly.
Hi dubie76,
Try an app called OCLF 2.0 on the Market. It is a Lag fix app for the Samsung Galaxy S which also works on the Tab.
https://market.android.com/details?id=com.rc.QuickFixLagFixR2
You have to install EXT2 tools and then install one click lag fix, both are done within the app.
I had this on my Tab before flashed to a custom ROM. The tab was much faster and did not have and lag compared to stock, the Quadrant score was around 1900.
Also you can uninstall the modifications in the app and easily reverse back to stock. The only disadvantage is you will loss about 800mb of internal memory (the 2Gb space), so if you don't have much space left, you will need to uninstall some apps and reinstall them once you applied the lag fix.
P.S. thanks to OP for the SystemApp Remover & Startup Auditor suggestion.
Custom ROMs?
Hi everyone!
Consider this:
The locked GTab (in standby) on an original ROM with a connected to it BT headset wakes up after replying a call from BT and can potentially have anything pressed as being in the bag due to its size...
My point is that there is NO fix for this on XDA therefore why should I expect any significant advancements from a custom ROM if such simple things cannot be fixed on Android.
My personal view is that Android is unfortunatelly not as flexible for adjustments as WinMo (i have HD2 as well with a wonderful custom Artemis ROM).
I've tried two Roto ROMs on my GT and they havent provided any noticeable enhancements in performance to my eye (perhaps some rating went up - I dont care about tech stats). I reverted to stock ROM P1000XWJMI that works as fast for a "regular user".
I am sad to resume my experience with hacking the GT as not worth it: you get serious risk of getting the GT bricked (much more complicated than with WinMo), loose the warranty and are open for instability and sudden incompatibilities with crashes.
On the third custom ROM installation attempt I was stuck on a black screen after powering on (stuck on the bootloader!) and couldnt initiate flash for multiple times. I was shocked and very nervous. Thats when the stock ROM saved my ass and I am not willing the risk of playing around any more with non-firmware ROMs for Android GT.
Regarding the alternative screen lockers available - please do not suggest Screen Suite (the best of the worst) and things like No-Lock (to get rid of the original locker) as they all mess up once in a while (tested) with the default ROM settings and the original core locker.
PS
In my view the best thing we can and should do first of all is to COMPLAIN to SAMSUNG Tech Support and Software Developers (I did twice already).
If every one of us from theese GTab forums would do this they would definitely get faster with resolving issues.

Looking for some advice as I am still pretty noob-ish. I apologize in advance if this thread is out-of-bounds in any way; every search for answers that I've conducted always seem to beat-around my questions. Any advice will be thanked ASAP, even if you can shoot me a url to the advice I need that would be awesome. If it appears that I'm on top of things that would be great to know as well. Thanks in advance!
I'm running CM7.1.0 Encore Signed emmc with Tiamat v4.1.0 kernel; using Ram Manager Pro for optimization in lieu of task killers, Nook Tweaks for CPU stepping and voltage management, "Antivirus Free" for virus protection, "Battery Calibration" to monitor/obtain max charge (~4200 mV), and "Set DNS" for faster web-based loading. I've also disabled Android Cell-Standby Services through ADB and removed useless apps such as camera and voice apps using Root Explorer. My biggest questions are as follows:
1. Am I running the best kernel for speed and battery saving?
2. What are good voltage settings for better battery conservation (currently on default voltage settings)?
3. Is there really a need for a virus protection, and if so is there something better than what I have?
4. Is there any settings that I should know about for "Set DNS" (didn't change settings, just installed and activated it)?
5. Are there any other technical ways to adjust battery consumption (have to charge every night under normal use)?
I keep telling myself that I'm probably good to go, but I want to be certain that I've been as thorough as I can be. If anyone does something differently with great results please feel free to advise! As I said before, any advice or even just urls that help with my questions will be thanked.

Sounds like a good setup. You may experience market issues by removing cell service and camera, some apps may not show up. My question is how did you get tiamat's kernel to run on the nook?

I'd like to know that as well......
I used Tiamat's latest Evo NON SBC Kernel ( http://tiamat-dev.com/tiamat_evo/ ). After downloading I installed the zip through Clockwork (after wiping both caches) in boot-recovery and I'm guessing it's working fine... what issues have there been with Tiamat's before?

No issues reported, because the only kernels around this forum are Barnes and Noble source. Let us know how the battery life is. Not to question your integrity, but did it stick, showed up in settings, about tablet?
That's a great point. It didn't stick. All seemed well when I installed it but I guess the long pause on the next reboot was from the system restoring the last kernel I had. After looking around some more I came to realize that in order to have control of CPU stepping with Nook Tweaks you must have Dalingrin's 2.6.29 OC Kernel 09/01/11 (http://coachz.inetpro.org/~dalingrin/nook/kernels/090111/) or later. So that's fixed.
Meanwhile my battery is only good enough that I have to charge it at the end of every day under normal use, sometimes earlier.
After that, my list of questions fall to:
1. What are good Nook Tweaks voltage settings for better battery conservation (currently on default voltage settings)?
2. Is there really a need for a virus protection, and if so is there something better than what I have?
3. Is there any settings that I should know about for "Set DNS" (didn't change settings, just installed and activated it)?
4. Are there any other technical ways to adjust battery consumption (have to charge every night under normal use)?

Sounds like your battery drains about normal. I lose around 12 to 15% per hour, always have. I have tweaked the voltage some, but did not see much of a result. There is is no need for virus protection that I am aware of. I have not seen a single thread on that issue (I have been around this forum for a year)
I can't advise on any DNS settings. You may want to play with the voltage some and see if that makes any difference on battery life. By the way, there is an updated kernel in the development forum in MiRaGe's kang build. Look for it in the OP. Also his build, for me, is the fastest and most responsive that I have used. Good luck.

Thanks for the advice... I'll look up the kernel and see how it goes.
1) There's some voltage stuff listed here
2) I don't use any, it seems to me like most malware is centred around phones anyway. I just use Droidwall to block internet access for anything shady-lookin'. LBE lets you block more permissions, or CM7 will too, but with no SIM, no mobile data, no GPS, there is just not as much to be concerned about on the nook . Basically, being aware of what Permissions are, and checking them, should keep you safer than relying on a faceless, profit-motivated company.

4) If you're interested, Tasker can be used to under/overclock any app. So, your flashy game will run at 1200, your simple text reader at 800, and so on.

Thanks! I'm definitely gonna purchase Tasker now, as I've been looking at it for a while... and I'll check out the voltage and the security links for sure.

This is where I got the info;

Hello.
I've got a stock Android 3.2.1 (A501 4.066.29 COM GEN1) rooted with Stock/HV/Taboonay V3.7 for HC 3.2 16-10 - 1.64Ghz/UV control kernel.
The question is:
how to set cpufreq parameters (governor, max_freq,..) WITHOUT using 3rd party apps so that the parameters were restored after reboot.
Thank you for reading this.
Either the kernel needs to support init.d scripts or a service needs to execute on boot.
That kernel doesn't support init.d and Voltage Control has a startup service.

Forgive my ignorance but I can't put to use your answer.
I don't get where is Voltage Control and what I have to do.
Get Voltage Control from the market, make adjustments, save as boot. You'll be given the option to save as init.d script or startup service.
Well.. I tested it. Odd app.
First of all it can see only one core. It's funny. After reboot cpu0 works in conservative mode, max_freq 1.4 GHz and cpu1 in ondemand mode, 1.0 GHz.
I tried to edit init.d script and add the 2nd core but after reboot cpu worked with the default kernel values - script didn't work at all.
Moreover Voltage Control shows voltages turned upside down - the less cpu frequency the bigger voltage values. I fear to use this app
Download setcpu or antutu cpu master it recognizes dualcore , has the boot option
More education would be advised To you PLEASE DONT BREAK YOUR TABLET
Please do not take this the wrong way..
it does sound like you do not know what your doing.. I suggest you read more about over clocking./under voltage of a TEGRA 2 DEVICE.. That will get you more understanding about what you need to do. And maybe even help you decide if you really want to do this or not.. There is alot of resources online about this subject. I have tried custom kernel with set cpu.. I use it on my 650 mhz phone. clock it to 768. but it has a huge battry issue when running at that speed.Not to mention It would be dangerous to leave it on my purse with something running might be a fire bug.. GOOD LUCK .
Basically lower voltage at higher frequencies keeps the CPU stable. Leaving it linear would increase temperature exponentially.
Script Manager can run scripts on startup but I don't know how you could disable them if they keep it from starting up.
I didn't know about VC and dual core though. My bad.

I tried all cpu related apps from the Market that I was able to try. Now I want to try to get along without them.

I don't understand? You want something that does the same thing but you don't want to know it's there?
I found one app called System Tuner that lets you adjust CPU frequencies individually. I don't know why though.

Actually I don't like how these apps work. And I thought that setting up a few parameters would't be difficult. It seems I was wrong.
Yep. Code has to execute to do stuff, otherwise that stuff doesn't get done.
System Tuner Pro allows voltage adjustments on overclock settings. If you're interested. Also, has a lot of packages integrated into one (task manager, app freezer, etc). They have a free version in the Market if you're interested. It's nice to have several apps, in one nice package.

Thank you but I actually don't need it anymore
I have rolled back to the stock kernel because of constant "sleep of death" issue.

It's because the 3.7 kernel you used, is really not compatible with the a501. The ultra-low voltage causes "screen freeze" and the "sleep of death" when under 3g only. It's a known issue with the 501 and 3.6 and 3.7 kernels also. I would reccommend RTrips 3.4+. Probably his best for for a501.
I ship it with my own Alexandra II and III rom. No issues with it, and none ever reported.
Had I noticed when I woke this morning, you had an a501, I could have given this advice. Sorry, didn't have enough coffee

The problem, is that a lot of dev's, don't have a501's, only a500's. So they really can't test a lot on it. And sometimes, the issue doesn't happen for 2 or 3 days. Sometimes less. I'm going to experiment a little this weekend, with some of the newer kernels, and mess with the voltage's and see if I can get it stabilized where it doesn't freeze on 3g only.
Moscow Desire ,
Thanks for clearing it up and the advise. I'll try either 3.4 kernel or your ROM.

If you go to RichardTrips kernel thread, you will see a link to his older kernels.
You will find the 3.4 listed on his server. I think you just need to flash it, although I usually dump Dalvak cache.
Alex II is an easy install. Alex III (3.2.1) is a little more ... interesting to install, but not difficult. If you run into an issue, post it in my thread. Everybody else has got it installed, so I think you'll have no issues either.
It's the only "certified" 3.2.1 for the Acer a501 that I know if. Not that the other roms are bad, because they really are good, but, the 3.2.1 they advertise, are from system dumps after running an update, or adding missing files to a 500 rom. The TMPL is an Acer release.
Hi guys,
I own an Nexus 4 with parts of the screen not responding. I got a new phone now (Ecoo E04 Plus), now I want to build a iPod-alternative. Now to my question, whats the best ROM for that purpose? It needs a long battery life in airplane mode. Second question anyone nows an that changes ur homescreen to a nice media player? (I thought of Themer) And my third question is what kernel would you prefer? Thanks for your help.
Lukas
PS: Sry for my bad english, I'm only english basic course.

i would suggest stock rom with a few mods or a custom rom. the important thing is custom kernel.
the way i would do it is:
1. stock with xposed framework+gravity box. that way you can enable volume keys to change track
2. chroma rom. ia currently use chroma rom an it is rock stable and it has tweaks built in one of them is volume keys to change track.
in both cases i would install a custom kernel f.e. franco kernel for better battery life. if you want to maximize the battery life you can undervolt/underclock/disable cores. my phone is always undervolted 150mV.
my advice is undervolt (undervolting to much will reboot your phone. my cpu undervolt limit is 150mV so keep that in mind)and disable two cores. two cores are already capable to handle everything. the cpu frequency should be 384mhz - 1.3ghz or 1.5 ghz. see what is good for you. know that the higher the mhz the more power you need
also remember to disable sync and, if you don't need, don't install google services for battery again.
for maximizing battery i don't know which android version is best. i would go to android 4.4.4 or 5.1.1
for home screen i would suggest a widget. also you can also make your player start automatically when android start. there a lot of app in playstore for that.
P.S. if you encourter any stuttering during music playback one reason could be the low frequency of the cpu. i had a problem like this some time ago that is no more on android5.1.1. the solution for me was to change the lower cpu frequency to 512mhz or 700mhz. this solved my problem.
P.S.2 for changing the kernel setting i use franco kernel app. it is a paid app and simple to use. the free franco kernel will flash the appropriate kernel for you. you can find a lot of apps in the store that are free one populare is synapse if i remember correctly.
if you need anything else feel free to ask. hope i helped
