General :: How To Determine What Is Keeping Android From Deep Sleep
Jun 5, 2012
I have an HTC Rezound running Android 4.0.1, and I notice that it very rarely enters sleep mode, even after the screen has been off for a very long period of time.
Is there any way I can determine which apps are keeping the phone from entering sleep mode? ..or which app is waking it up constantly, whichever the case may actually be?
I have tried doing a logcat and just let it run for a while after turning the screen off, but I'm not quite sure what to look for in the results..

my phone (xperia x10i, unlocked bl) doesn't enter deep sleep and CPU Spy shows deep sleep among cpu unused states.
I have obviously looked for all the tweaks in several threads, with no result. Though I am using Cobrato Miui 2.3.2 with the kernel modded by Cobrato himself, I will try another kernel and somehow I'll get out of trouble.
- if is there a way, from xterm, to access kernel-config, without using an app with its UI (I don't like UIs, which I find misleading);
- if I can check via terminal emulator how deep sleep is configured and what it actually is, because answers like "it is a conservative cpu status" don't mean much to me, I'd like to know the frequency of deep sleep for my phone and if it can be blocked or activated in any way.

my Infuse 4g uses 25% of the battery when it's in deep sleep during the 6 hours I sleep. Yes, it is in deep sleep. Yes I have BBS. There are only one or two wakelocks for only a couple minutes each for twitter sync and things like that. How can it possibly be using that much battery in deep sleep? It's on CM10, but the problem only appeared after having it installed for several days. Normally I get maybe 2-5% use over my sleep period.
I thought deep sleep = deep sleep and it has a constant near-zero power consumption.

I have a sony xperia u running ice cream sandwich. The google maps app keeps on "restarting" status when I go to check the running apps. It is preventing the phone from going into deep sleep, therefore consuming 20% of battery overnight. This does not happens all the timeI have included a screenshot below.

I tried various methods now to backup content of internal storage of my Nexus 4: Plain drag-n-drop in windows explorer, commandline adb pull, Android Commander with copy or pull. All methods fail at the point where they get tho a bunch of files like this one:
Code:
/storage/sdcard0/Android/data/com.ptvag.android.adacmapformembers/cache/web/b/20/http___ajaxmaps1.adac.de_Default.aspx_ajaxmaps_MapServlet_left_938290_top_7193029_right_1251027_bottom_6880292_width_256_height_256_profileGroup_hd_version_ADAC_TourPlanerEU_2012_2_hiddenLayers_Town
Yes, this are 280 characters and Windows (7) seems to allow only 256.
Are there other methods to backup internal storage?

we already got a battery meter in android 4.2.2, and it can tell if something is keeping the phone awake.For example, it shows that the "Android OS" is keep the system awake for 10 hours, but it can not tell me which app is holding some wake locks or wakes the phone frequently.I also installed Better BatteryStats, under Kernel Wakelock, it shows that the gps_lock is holding for 10 hours, but also not related to any app.

Is there an easy to use and Free Android Upgrade App that upgrades the Android OS like from 4.0.2 to newest 4.2.2 while keeping settings and personal data and installed apps. Seems like a common sense thing since everyone expects this on Desktop OS updates right? why not with Android.

I am looking for Deep effect in Android gallery. i did some work around coverflow at http://www.inter-fuser.com/search/label/Coverflow but it also do scroll left and right. it does give me the idea to calculate offset top and left for each item separately but still there is no access. what i am trying to do is, when user scroll, images would scroll from deep behind the right edge to center and then to left side deep behind.i am wondering if anyone have some thought about arranging the imageView's on deep offset (something like V shape ) rather than on horizontal as it is.

When I get handed a new and previously unknown Android device (typically from a minor player), is there a way to figure out which components it is made of, such as the SoC, the flash chip, the RAM type etc. (Assuming noone else has posted the info of cause)?
In other words are there any tools (other than a screwdriver) for finding this out directly from the device, preferably without rooting (as some of this info may be needed to pick a rooting method...)?

My phone is Jiayu G3S, with a MTK6589 cpu and android version 4.2.1 I use latest xposed installer and latest gravitybox.
My problem is that something is keeping my cpu busy in the background, preventing it from sleeping.
For example, i left it last night, and i opened it after 12 hours, it was awake and using cpu for about 90 minutes.
My normal consumption is 0.3% every hour, but now it is 3%, like 10 times more. Also noticed greater consumption when screen is on. As you can see, there is no strange wakellock that lasts that long and all my apps have settings not to auto-update. I tried reading my logs but i didnt find any info.

I just bought a new new Android smartphone, and electronically and mechanically, it works very well, and gives a nice appearance. It was sold as having Android 4.1.1, and About Phone -> Android version displays 4.1.2. So in this version range, we are talking about Jelly Bean, right?
Software version in the 'About Phone' begins with, '6820_2.3.5_' but whether or not this identifies the OS version, or means something else ...
I'd like to know if there's any way of telling exactly which version of Gingerbread my phone is running? This is useful in deciding which apps should or should not, be installed.
The phone has been rooted, has busybox and a terminal application installed, how to identify the OS that requires this capability.

Are services like Tasker now safe from being killing if running in the background?
I would prefer running such services in background instead of foreground to save space on the notification bar.
So I was wondering how risky is running services in the background with JB?

My dad's phone is running Android 2.3.5.
He uses a Hotmail address.
If he:Downloads the e-mails on his phone, thenDeletes an e-mail via. the website (mail.live.co.uk) ... the deleted e-mails doesn't disappear from his phone in the Email app.
This means he now has 500+ e-mails in the app when there are only around 50 in his inbox.

I don't want to use APK Multi-Tools or APK_Manager or whatever. I want to know exactly what those tools are doing in order to recompile the system apk while keeping the original signature.
What I initially did...
Code:
apktool d "%~dpnx1.apk" "%~dpnx1"
...modify files here...
apktool b "%~dpnx1" "%~dpnx1.apk"
But obviously that's unsigned. I need to sign it, but I want to use the original signature, which I'm guessing is the META-INF stuff, right? So I attempted this...
Code:
apktool d "%~dpnx1.apk" "%~dpnx1"
7za x -o"%~dpnx1-signature" "%~dpnx1.apk" META-INF -r
...modify files here...
apktool b "%~dpnx1" "%~dpnx1.apk"
7za a -tzip "%~dpnx1.apk" "%~dpnx1-signature/*" -mx9
You'll notice I now use 7-Zip to pull out META-INF from the original APK and then insert it back into the recompiled one afterwards.
The only other thing I can think of would be to go with my first method, but then use 7-zip to pull out the compiled files from the unsigned apk and insert them into the signed apk. I haven't tried that yet, but it will be the next one I go with. Every time this fails, though, I have to do a nandroid restore.
For those interested, after running "apktool b" (to build/compile), ignore the output zip. Instead go into the source directory and there is now a build directory. In that is an apk directory. Simply add your changed files to the original untouched APK (if you modified any XML files, then replace resources.arsc; if you added anything to smali, then replace classes.dex; if you added any XML files, then you need to include those as well; for me, i copied resources.arsc, classes.dex, and one new XML file). I used the following command:
Code:
zip -9 ..SystemUI.apk reslayoutstatus_bar.xml classes.dex resources.arsc
I use zip instead of 7za for cosmetic reasons. You can also use "7za a -tzip etc..." if you want.

Any way to lock apps in memory without keeping icon in status bar? I guess I have problem with Lux auto brightness and Keep Screen On. I turned off icon of this apps in bar, and they are stopping working I guess that is because android JB is killing them when there is no icon.

What is keeping my phone awake through the night and hence draining my battery rapidly. I am going to post screenshots and BetterBatteryStats dump file to make it as clear as possible.
Basically, what I see is that the phone was mostly awake at night and was in deep sleep only for about 1 hour. I don't think it is normal.

What's the best way to determine why all of a sudden my battery is losing it's charge more quickly than normal? I checked battery usage in settings and everything seems reasonable. I can't think of a newly installed app that might be causing it. (HTC Rezound, ICS) ADR6425LVW

I'd like to have Tasker read incoming texts to me while in the car but pause and playing media first. I have a profile setup to trigger the task and everything work, except the part about pausing the media. As it is now it just read the text over the top of the media and neither are understandable.
I've searched and I can't seem to find a reliable way to determine if media is playing, pause it, then play it again after the text is read. I'm familiar with %MTRACK, but that only works with some players (none of which I use). I typically use PlayerPro and BeyondPod.
