General :: I9100 / 4.0.3 - How To Disable Useless Services To Save Power
Apr 3, 2012
Recently, my phone is leaking power in a crazy speed. (i9100 4.0.3). Before sleep, I turned off bluetooth, wifi, 3G, gps, all motion sensors. Switched it to flight mode. After about 7-hour sleep, 10% battery was lost. This happened for the last few month.
I installed DX BatteryBooster, from its monitor I learnt that almost all the power went to Android System, if click at it, it says included packages:
Remote Device Management Service.
Software update
Video Maker
What are these services how do I turn them off?

I need to delete Google Play Service completely from my phone or totally disable it! Even when I disable it, using phone "disable feature" Google play service and all it's apps are still eating my battery 45% (Running). The only way to kill it it's root my phone? I can't find way to contact Google or Android there is no email on the internet! Many people want to delete Google Play Services I've seen a lot of threads but found no solution! I don't need Google Play Services at all.

I have a Galaxy Note II. When I have it in the side pocket of my pants I sometimes reboot the damn thing by crouching down. I listen to audio books when renovating my cabin (which is going to take a month or so more), and this has happened 4-5 times today! So I'd like to disable that button all together. It just has an idiotic placement on the phone. I prefered my old HD2, that had a power button on the front that actually took a bit of pusing. This thing is pressed by looking hard at it!

How to disable the baked-in power saver feature in some Samsung Android phones? the one that dims the screen, turns off the keyboard backlight, and doesn't let you use the camera once you hit 15%(or 10%) battery left? can't stand that, for my own needs anyway!
i figure it might be an edit to the kernel source code, or something like that. i just don't know where to do that. I know it can be done tho, because i remember having some ROMs on the Epic 4G that had that junk disabled. guess i'll also see if some of those old devs. are still around.

At first when I used my phone. I would click on Internet, Browse to a web page, and if left my phone alone for a few minutes it would go to power save mode, and I would have to unlock the screen to keep browsing on the same internet page I was on. Now when it powers down, and I go back to it, it always defaults to my home page, and I have to browse back to the page I was just one. I have been looking for a setting to undo this, as its driving me crazy, but I haven't been able to find a way to change this.

I had an encrypted I9100 on Cyanogenmod 9. After a factory reset I installed Cyanogemod 10.1. Everything runs smoothly, but about 12gb of my internal sd space was misplaced during the installation and is now missing. Only 2 gb is currently available. /sdcard cannot be mounted, something about /sdcard/android_secure
I ran some commands in adb, and the space is still there, but it needs to be replaced / repartitioned somehow.
df -h

/dev/block/mmcblk0p7 98.4M 87.0M 11.4M 88% /cache
~ # mount /data

I'm looking for some custom Jelly Bean 4.3 Roms based on official Samsung Rom for my i9100, so it would have Touchwiz also.Currently i keep switching between CM10.2 (4.3.1) and Wanamlite 14.7 (4.1.2).
I like Wanamlite just because it uses the Samsung Touchwiz interface i like so much. Other than that, any other stock Rom, rooted and debloated would do just about the same.What i like about CM10.2 and cyanogenmod in general is the speed and stability the Rom feels like. Also, the latest 4.3 Roms gave me infinitely great battery lives compared to any other JB Rom i tried since. And judging from other posts and reviews on the internet, Google worked their magic on 4.3 for small batteries run through the day (almost double the life of 4.1.2 or even worst 4.2.x). So it seems the perfect combo for me would be a 4.3 custom with TW.

I have a Galaxy SII running Samsung 4.1.2 ROM rooted and deodexed, but the /system folder only has a limited amount of space even though I have 16GB internal memory, is there a way to sacrifice some usable memory to get more /system memory so I can add some stuff to /sysem/app etc?

I want to use GPS service for better accuracy in my program, but want the location only once in every couple of hours. To get GPS location the GPS had to be started already manually through Settings->Location Security->Use GPS Satellites. But the problem is GPS continuously running whether I need the location or not and drains the battery quickly. My question is what is the equivalent API for the checkbox selection of,

I'm able to add the entire power control widget but I'd just like to add the individual buttons like it had preinstalled in the first left extended home screen (WiFi, 4G, GPS and bluetooth). I'm sure I'm missing something terribly simple here but I've looked everything.

I need to know that I have received a text when the phone is on power save mode.
At the moment I have to unlock it and check, just a light flashing at the side telling me or some sort of noise or anything would help.
Is there anything I can do for this?

I'd want root access is to install Titanium Backup or a firewall to freeze/block access to a certain Chinese Android Market app. The app in question sends out a notification to feature new Chinese apps everytime the phone is given internet access and there are no options to disable it within the app itself. And since it came with the phone, it cannot be uninstalled, and of course, it restarts immediately if stopped.
One-clicks do not work-- they all result in directory/permission errors. For example, superoneclick will hang on step 7 and doomlord's method would reboot the phone without making any changes.
It would seem my only resort would be to use a different ROM, but there are no ROMs for this phone. Of course there are methods using similar MTK 6573 phones which are usually just clones in different casings, but I've read that using non-specific ROMs will result in a brick as there are slight differences.So how should I go about rooting this phone? What are the risks of using a non-specific ROM?

I'm on gs2 I9100 cyanogenmod 9 and can't find a solution to encrypt internal databases like sms, call logs, contacts... ( so in /data).
No problems with documents in container created by luksmanager. But i wonder is it possible to make a sort of preboot script who mount after correct passphrase a luks container who is symlinked in /data ? Because android ics built in encryption installation stop at beginning.
Is there now new method or app to encrypt full or partial phone? Maybe new encryption function or improvement in JB? Pattern/face unlock fixed?

I'm a Galaxy S2 GT-i9100 user and I wanted to know how to run touchwiz in tablet mode. Do i have to decompile SecLauncher2.apk and edit the code so that it becomes accurate when using with landscape mode or is there an xposed module. Or do i edit build.prop file? I don't want to install other launchers or get ParanoidAndroid.

When I got my phone at the end of last year I rooted it using a Chain-Fire kernel - v 4.2, I think. After flashing, it worked perfectly, since when I have flashed the old bootloader to get my USB Jig working to remove the yellow triangle and flashed a patch again to allow the USB Jig to reset the binary counter.
I have very much wanted to install and get the new Sky Go application working.
What I had to do was flash the Stock kernel for my Stock Rom - I have never messed with my Rom - it is Gingerbread 2.3.4 in a CPW phone here in the UK.
Doing the flash and installing Voodoo OTA (to temporarily hide my root) has been enormously successful
Now then to my query....
The original Chain-Fire mod v 4.2 installed CWM.
After of course cancelling the "hide root" function to show my phone as rooted once more, I went to do a backup, using CWM but it refuses to work. It says my kernel needs v 5.0. Obviously the Stock Rom I flashed to get Sky Go working has thrown CWM some what.
I have downloaded Rom Manager from the Market but this seems not to work either - it starts to work (reboots) but then halts with the following messages: -
E : failed to verify whole-file signature
E : signature verification failed
Installation aborted
What I would like is some way of installing a backup previously made before flashing the Stock kernal and also to make a fresh backup now.

For the last 5 days I am experiencing extreme battery drainage(Android OS nearly 100% Battery Usage ). Back when it began I did not install anything suspicious or battery consuming software. I never go full screen brightness, and all unnecessary apps are either deleted or disabled. I have tried Factory Resetting, Wiping all possible caches, systems, internal/external SD cards. I even tried manually deleting all folders from my PC. I have tried installing custom kernels, roots and even stock ROM. Right now I'm with stock ROM with CF root.
Phone state: Model number- GT-i9100; Android 4.0.3; Baseband v. i9100XXLPS, Kernel v. 3.0.15-i9100XXLPQ-CL223505 se,infra@SEP-94 #3; Built number IML74K.XWLP7. And here is what I get from the battery report :
i41.tinypic(dot)com/1j9nae.png
I have tried full discharge and charge to 100% and calibration. Even cleared the battery stats It just doesn't work. I am using Nova Launcher. Even after going back to TwLauncher I am still getting 98% Android OS usage. I don't use Data Mode and Wi-Fi isn't always on. When charged and calibrated at 100% at 21:00pm, in the morning at 9:00am phone battery is completely empty and shut down.
I'd like to use the stock ROM, with a nice battery stable kernel & still with Nova Launcher. NOTE: This is still happening with a NEW battery.

I have seen allot of posts stating that you should disable the GPS to save battery. I may be mistaken but if no apps are actively requesting positional data is it not off? I have mine set to on and it does not even register on the battery usage screen.
