[APP] Rom Toolbox

If you haven't tried this app already, definitely give it a shot. So many features. It basically incorporates Titanium, Root Explorer, Voltage Control, SetCPU, SD Card Boost, ROM Manager, TMobile ThemeChooser (for CM7), Terminal Emulator, Ad Blocker, Rebooter, V6 Supercharger, Autokiller, Font Installer, Custom Boot Animations, Battery Icon Changer, Boot Logo Changer, and probably several other common Root apps all-in-one. You can mess with Build.prop tweaks, vm heapsize, sysctl tweaks, and more. AND it lets you Apply any changes you make on Boot.
And the best part.....ALL FREE!!!! (though there is a donate version, not sure what the extra features are - but all I mentioned above is in free version)
Let me know what you think:

Check out Imoseyon's recommended settings/tweaks as well here.

great app
Thanks for the tip...I just got it and MAN is it amazing! I'll play around with it some more, but if it holds up...I'll buy the donate version. Really good app!

Just found this today as well. Super useful.

what other things can you set at boot in the paid version that you can't in the free version? cuz u can set governor, sd card read speed, and other things at boot for free..

possibly a result of some tweaks i just made using Rom Toolbox, I'm flying right now. Faster than ever. Here's what I changed, just in case anyone can point out if I did anything bad:
Auto memory manager
6,8,24,30,40,50 (same as Aggressive 1 settings in V6 Supercharger)
vm heap size = 32
sd boost = 3072
Min Free KBytes = 4096
Dirty Ratio = 90
Dirty Background Ratio = 70
VFS Cache Pressure = 5
Oom Kill Allocating Task - SET ON
Applied everything at boot, obviously. I did a little research on what to change these values to, and so far these values have definitely sped me up considerably.

Great so far. The improved performance is even more noticeable, however. only thing you might want to change, if you know what it is, is the oom kill allocating task setting. a lot of people seem to leave it off, but from what i understood it did, keeping it on should save more battery and just operate more efficiently (makes the killing off of tasks to regain ram less random). so far there's been no downside to having it on. also, you might want to test out putting the vfa cache pressure setting to 1. many people do that, too.

It requires the pro version to freeze apps

hey just want to ask a simple question ....
i am having samsung galaxy s2 and i had update it with 2.3.6 stock rom KK5 and i want to change the battery icon on the taskbar. but as i change it. my phone didn't boot and stuck on sangung galaxy s2 logo. even didn't find the boot animation or sound..
i didn't make any changes except the battery icon.
even my phone is root.

Well, he did make the change with Rom Toolbox. To the guy with the battery issue, I think you need to be on a deodexed rom to change the battery.

WOW!!! The speed change is amazing!!!! hard to believe that just a few tweaks did that!

Bought the pro version of this. Tried to change battery icon and it froze on boot logo on reboot. Tried to refund and it won't refund. Will be emailing the developer.

Yea... don't get me wrong I'm sure all the functions work great, and it's not like I tried anything else with it. Having one freeze was enough for me to stick with the ways of doing things that I know I never have issues with. But knowing me I'll just keep the paid version and try again at some later date. Maybe something just glitched during the reboot.

Not sure if this will help, but I have the pro version as well and was able to successfully change the battery icon. I liked having the number off to the side so since I have the ICS theme on my phone, I used that battery icon. I think it's 'Bar Ice Cream Sandwich'.

[SHARE] Battery Saving Techniques!

NOTE: Im turning this into a sharing thread where everybody can post and share their techniques on how they save battery consumption. I'll quote all the useful suggestions here in the first post
I would like to start off by saying that all ROMs basically consume badly just like the stock version. There could be little to no differences between them with regards to battery performance. Right now I would like to share my observation, on what I presume to be one of the best ways to save battery while maintaining good performance.
glennlevi's Technique:
1. Get Antutu Battery Saver Pro (Free version can be found in the market). Install and untick the option control cpu speed.
2. Using No Frills CPU, or any other built-in cpu settings app, select your default governor (bcm####) and sio as your I/O scheduler. Maximum Frequency should be your highest available, and Minimum Frequency your lowest available.
3. Manually adjust screen brightness in settings to about 20%.
4. Untick Background Data and Auto Sync in settings, under Accounts and Sync Settings.
5. Get Ram Booster (Free in market) and install. Open. Under settings, set Boost Level to aggresive, set whitelist apps and tick your launcher, sms app, keyboard, and Ram Booster and Antutu Battery Saver. Untick Show Overlay Widget in Overlay Widget Settings. Enable the widget in the notification bar, refresh every 5s, Report Style Dont Show. Under Advanced Settings, set Feedback to None. Clean Ram using this app everytime just before you turn off your screen or want to stop using your phone.
6. Drag down your notification bar and tap the Ram Booster Notification. Now wait a couple of mins while browsing through your phone (without opening any apps)
*You can use other task killers if you want, but Ram Booster is the best IMO. A better replacement however is 360 launcher's cleaner widget (which will save more memory, ram and battery usage since its all in one app)
7. Open settings and go to Applications>Running Processes and look at all running apps, you will see some auto-start apps like Beats Audio, DSP Manager, Google Mail, Google Maps, Google Playstore and others. Uninstall all user apps that have autostarted. Download Titanium Backup and use it to uninstall stock bloatware, like google maps and google mail, or other custom bloatware like Beats Audio (If you dont use them at all). Clean Dalvik Cache using Titanium Backup and Clean Cache using Ram Booster. Freeze seldom used apps like Google Playstore. Just unfreeze when you want to use them.
*You can use other apps like Root Uninstaller to remove system apps, but IMO Titanium Backup is the easiest to use and has one of the most functions.

Imacatlover's tips:
Imacatlover said:
The best way to save battery is really to know your fone.
1. any type of widget should be avoided( except maybe clock) as they are juice hoggers.
2. ANY app that suggest or implies that they save battery defeats their own purpose for they themselves consume battery life...figures.
3. ANY app that has "killer" attached to it isn't really helpful because most of the app be it user or system just restarts after. Same goes for anything with "booster"..
4. Ram cleaner should suffice
5. keep most settings to a minimum.
6. Accept the fact that our little fone has one crappy battery construction..

irfanbagus said:
i do. well, not full kernel, just kernel module. search bacem-tweak in dev section. but i find that the best thing you can do to save battery is keep your phone sleep as long as possible. that's means remove bloatware, limit installed app with service, and only turn data/wifi when needed. combine with undervoltage, usually i got 3-4 days in single charge. in some very rare condition i got 6-7 days.

Well, most custom roms are rooted anyways. Im just saying this cuz you might be running on stock rom

First off I would like to quote myself -
"Right now I would like to share my observation, on what I presume to be one of the best ways to save battery while maintaining good performance."
As such, Im sharing this because
1. I think it might help other people.
2. I've tried it and compared it many times in many different rom, and what I recommend is based from my own experience
3. I know youre a dev. Im not, obviously. That doesnt mean I cant share what I think is useful. This is also backed up by the fact that Im not claiming Im sure that these actually work and that I can back it up with additional information. Again, this is just based on my experience.
again I would like to repeat the quotation from myself:
"Right now I would like to share my observation, on what I presume to be one of the best ways to save battery while maintaining good performance."
There you go. I hope that clears it all up. So please dont pick on me or anything just because Im not a dev. Thank you.

nope...I never intended to pick on you. I'm just feeding up my curiosity. I'm sorry if you feel like that.

thanks for sharing we need tat support...other be frank..be opened for sharing..

Well, thanks anyways for noticing my thread. Now I know some of my suggestions may be far from the theoretical facts that you know, but there are times when actually testing something and comparing it with others yield better results than just looking up the figures. Thats just my take on it though, so Im not saying thats all there is to it.

Sir i want to ask you onething, offtopic, in nexus there is no memorycard slot, so we have to keep all data including gallery files and even a new rom in phone memory. If we want to flash a new rom, then how can we do that? While we wipe the data and cache before flashing all data will be deleted? The rom file too?.

Tweaks for saving battery without compromising on performance

Battery is one of the things that's critical for your mobile's day to day use.
I have done my research on the things that has impact on mobile phone's battery life and I am going to jot down the stuff that can clearly save your battery.
1. Changing your scheduler.
By default Android devices comes with CFQ(COMPLETELY FAIR SCHEDULER) which is the worst, So please change it to SIO(SIMPLE I/O) scheduler, This scheduler has been voted as most stable and better for battery. It even solves the heating up issues.
NOTE: DON'T NEED TO OVERCLOCK OR UNDERCLOCK your device if your planning to use your device on a long term basis, Changing the scheduler will do fine
2: Install wake-lock detector
The wake-lock detector requires root, It gives you the idea of what rogue apps makes your device stay awake, Staying awake drains a lot of battery, Best thing to do is to uninstall the rogue apps.
3: Do not install Battery saving apps
Let it be any application, They claim they save your battery by monitoring the unnecessary background apps and closing them. They don't let the device to sleep, Let it be juice defender or you name it. Do not do that.
4: Install push notification fixer
Complaints about push notifications are solved by this APP, It resets your ping time, So that you don't spend unnecessary juice trying to connect to the server.
5: Disable google now
There are better apps which can tell you weather reports, If you feel like you are depending upon google now, Just disable "LOCATION HISTORY" and "LOCATION REPORTING".
6: Wiping cache and Dalvik cache
If you have restored apps using a back-up tool such as Titanium backup please make sure you wipe cache and wipe dalvik cache once you are done restoring, It just optimizes your apps.
7: FACEBOOK MESSENGER AND VIBER wakelocks
As useful as they are they cause so many wakelocks, Use default facebook app for messaging and VIBER app can be greenifed using GREENIFY. Whenever you need it you can use them, Once u open the app u can get the missed call info as well, So if your real hungry for battery do this.
8: USING GREENIFY
Frustrated about apps causing wakelocks, Install GREENIFY and forget it. The app will be available whenever u need them , But it won't run on the background thus saving battery.
9: Do not manually close APPS
Android has got it's own task manager which does a pretty good job, Each time you close and open an app each requires more juice, So let android handle with the task and stay relaxed
10: Turn your sync off
With push notifications on, You will get your twitter updates and hotmail without sync, The only app that requires sync is GMAIL, which you can do it manually
I am posting my screenshot as proof.

Hi all,
I don't know if it is a good thing or idea i'm doing everything but so far it is working for me and I would like to get your opinion about that method for using less battery, the fact is that I always use my phone on 2G and wifi and GPS is on only when using them but for the apps I always force stop them and they remain stopped unless I open the app once again and I found I gain on my battery usage with my battery lasting for 2 to 3 days depending on the usage (many sms, sometime facebook, viber and whatsapp, messenger) but I force stop when I finish.
Do you think it is a good idea to do like that??

Don't change the kernel.

Kernel is like the heart of the ROM bro, DEVS have taken good time finding out which is best suited for stability and battery life.
I am using SENTINEL ROM and i have the sentinel kernel that comes along with it, I don't want to experiment with it, Coz it just works fine.
The kernel that comes along with your ROM should work fine, In case you want to experiment with other kernels you can do so, But you will have to find the one that best suits your ROM :good:

Everytime you manually close your app, It will take more battery to load up the next time. The default android will watch your usage and kills it accordingly. It is best to leave it to android. Cause everytime you launch a app freshly there is some extra drain. So best to leave it to android.
I used manually clear the apps as well, But now I never do that, Guess what i get better battery :good:

Performance Improvement

Let me introduce myself first. I have been developing software for Windows for almost 20 years. I love to tweak and tinker. That is what drew me to the Android platform. With that said, here are my findings:
I own a T989. I love the phone. I have tried numerous tweaks and scripts etc out there. In the end I found some very minor tweaks that I have done manually that make a noticeable difference in performance and a battery life.
The biggest increase in performance and battery life that I had noticed was going from a stock rom to CM 10. I am currently on CM 10.2 (and eagerly awaiting a stable version of CM 11).
With that said I noticed that if I changed just a few minor things CM 10.2 runs considerably faster.
Here is what I have done:
1. Disabled ZRAM completely. I have noticed that my phone boots faster with it disabled. I noticed that multitasking was not as good with it disabled but the phone seemed much snappier.
2. Changed Min Free values. I used the Performance Control app for this. My settings are currently as follows:
Foreground Applications: 16 mb
Visible Applications 18 mb
Secondary Server: 23 mb
Hidden Applications 42 mb
Content Providers 49 mb
Empty Applications 56 mb
This seemed to help a lot with multitasking and now it multitasks fast and the phone is much snappier and less laggy. So far my phone is very stable and fast.
3. Set SD Card Read Ahead to 2048.
4. I also left KSM disabled and left Allow purging of assets disabled.
That's it. My phone is rock solid stable and fast with these settings. I also noticed that my battery lasts about 15% longer. Even better than just switching to CyanogenMod 10.2 alone.
Let me know if it works for you.

I would absolutely love to try this, but I don't understand majority of what you wrote. I'm familiar with cyan though..

Disabling ZRAM is CM is easy. Under the performance menu just go to Memory Management > ZRAM. Select Disable. Reboot.

Oh I'm running slimkat on my i9205 mega and downloaded the performance apk. And I'm running beanstalk on my t989
*MEGA 4.4.2*GS2 4.4.2*2SHAYNEZ*

I updated the OP with new Min Free settings. I noticed that it wasn't as stable as I thought. After using it heavily all day I updated some apps in the Play Store and the launcher hung and everything was slow until I rebooted.
I then changed it to the new values above and used it very heavily. I made sure at least 18 apps were open then reinstalled those same apps from the Play Store (I uninstalled them first). So far no problems.

Moderator: Please delete this post. I accidentally double posted.

Is there a way to disable ZRAM on a rooted stock T989 running 4.1.2?
Thanks in advance,
rabilancia

As far as I know the stock ROM doesn't have ZRAM.

Let me introduce myself first. I have been developing software for Windows for almost 20 years. I love to tweak and tinker. That is what drew me to the Android platform. With that said, here are my findings:
I own a T989. I love the phone. I have tried numerous tweaks and scripts etc out there. In the end I found some very minor tweaks that I have done manually that make a noticeable difference in performance and a battery life.
The biggest increase in performance and battery life that I had noticed was going from a stock rom to CM 10. I am currently on CM 10.2 (and eagerly awaiting a stable version of CM 11).
With that said I noticed that if I changed just a few minor things CM 10.2 runs considerably faster.
Here is what I have done:
1. Disabled ZRAM completely. I have noticed that my phone boots faster with it disabled. I noticed that multitasking was not as good with it disabled but the phone seemed much snappier.
2. Changed Min Free values. I used the Performance Control app for this. My settings are currently as follows:
Foreground Applications: 16 mb
Visible Applications 18 mb
Secondary Server: 23 mb
Hidden Applications 42 mb
Content Providers 49 mb
Empty Applications 56 mb
This seemed to help a lot with multitasking and now it multitasks fast and the phone is much snappier and less laggy. So far my phone is very stable and fast.
3. Set SD Card Read Ahead to 2048.
4. I also left KSM disabled and left Allow purging of assets disabled.
That's it. My phone is rock solid stable and fast with these settings. I also noticed that my battery lasts about 7% longer. Even better than just switching to CyanogenMod 10.2 alone.
Let me know if it works for you.

Running JMT8 right now, and this has been one of the best posts I've seen on this forum. All roms I ever flashed would be snappy for the first couple days then slow to a crawl after a month. This has brought this phone back to life and prevent me from having to flash all the time. I wasn't able to do the ZRAM disable since I don't think I have that settings, but I updated the min-free settings and have seen noticable improvements. Thanks!

What does this do exactly?

Will SD Card Read Ahead 2048 not reduce the life of the SD? (and by a lot since my current ROM was 200% less.)

No. In writing a lot over time can possibly reduce the life of the SD. I don't believe that reading will.

I use ROM Toolbox to benchmark. 2048 usually yields better results overall.

Performance boost mod for ANY ROM [Scary performances]

I owned an gs2 b4 and used this mod its great performance booster.
It will work almost any phone and any rom(tested on nexus4 cm11 with similar hardware as zl and gs2 cm11)
ART Compatible (tested on nexus 4 )
It is not tested on xperia zl thats why i m sharing this but most probably it should work.
Plz do the backup before flashing because
I am only sharing this work i dont own this project
So sorry to say but i will not be able to answer any queries
Flash it at your own risk but it should work
Here you go with download link!
Improved gold edition
http://forum.xda-developers.com/showthread.php?t=2360670
Reverse Mod:
http://forum.xda-developers.com/showpost.php?p=43543566&postcount=62
Instructions:
Download the mod for your repective rom (download cm version for custom roms) from link!
1.flash it via cwm
2.wipe cache and dalvik
3.while rebooting system it will ask "disable recovery flash?" select "yes"
4.and there you go!
Note
If you select No in "disable recovery flash?" you will face problems in booting in recovery
If something messes up
Nothing to worry just do a clean wipe (data cache and system) and install your previous rom.(thats why a backup is recommended )
but most probably it will work.(recommended)
OR you can use reverse mod in the link provided

Well after using the latest cm on art, I can't imagine what would be faster ... Nevertheless will give this a try..... Its compatible on art mode right?

i have not tested it on art mode but you can giv it a try

Tested on PAC Rom nightlies.
Adaway stops working after that and ads show up in several apps.
Speeds up system ui animations and everything seems to be smoother.
But no impact on benchmark scores.
Also, battery seems to drain faster.
Maybe it has a better effect on stock version..

In my case I've got 70 more points in Antutu Benchmark and no faster battery drain.
Besides that, I totally agree with you.
Edit:
Found a "fix" for AdAway not working.
or use
su -c /system/etc/CrossBreeder/DISABLE_ADBLOCK

ACTUALLY THE MOD IS MENT TO DECREASE BATTERY USAGE for me it doesnt drain

Ok tested on cm11 and well... Doesn't make much difference... Few tweaks it enables is decrease the animation speed to .5x in developer options.... And allow plurging of assets in performance
Apart from that it does apply some minfree tweaks but in neither the benchmarks nor in normal usage do I see a change...
So yea I can't say it helps much in cm based roms where we could tweak the performance settings anyway... Maybe good for stock roms
Thanks for the share anyway

From my experiences on many different phone models and OS's and different methods tried, it might be good in short terms usage, but on the long run, benchmarks boosting leads to sluggish and buggy phone...

no i have been using this in my s2 since a long time until i bought zl it worked fine and benchmark is not boosted to a very high level maximus 200 it depends on the rom and it reduces lagginess

Yup it will but not much..
And to be honest.. Don't go for benchmarks ..
its all done quite easily as these boosters basically set ur cpu to performance mode whenever a fullscreen app runs.... That's it... If you look into it ull see most oems do that as well.. So u always get better benchmarks on stock roms as compared to aosp based roms.

i agree with you actually benchmarks arent that reliable for s2 it showed 200 but for many users its significantly negligibe.actually in the shared link its mentioned to increase benchmark thats why i had written "improve benchmarks"in title.rRemoved it now nomore quarrels about benchmarks!

Flashed the golden edition now and it gives me +480 Antutu points.
The fix for AdAway also works, thanks for that !
System ui responds fast and smooth. Will test it the following days and report back.

:good:

Guys the performance boost(If you feel benchmarks only show you the performance) comes from an increase in I/O score. Can anyone check that. I used to use such scripts on my galaxy 3 which atleast to some degree made me think the lag was gone . I don't think our phone needs such scripts.Our phone is already the fastest it can be and it's the fastest any phone can get right now . It can only be improved on by having better android( like an improved kernel?). Our phone has 2 gigs of RAM and do you think we need a minfree scipt for that? lol . That's the reason no one makes "scripts" for top tier phones. And those who feel the performance has been boosted check the CPU score differences in antutu, not the overall score which includes I/O too.

We do need the scripts buddy for our phones with unstable and laggy custom roms though our phones are good they arent the BEST !THIS IS JUST A WAY TO MAKE IT BETTER.if you feel so try it on ur phone.i personally dont go and rely on benchmarks
