[Dell Streak 7] TheManii:
It's widely known that the s7 has pretty weak battery life.

In general all qisda dell devices do (the s5/s7/venue).

Many of the bugs exist in the phone/ril and some exist in the logging systems.

In a bug free rom these workarounds should be completely meaningless, but stock roms are not at all bug free.

Recommendation one: Enable airplane mode on wifi s7's

The wifi and 3/4g roms are nearly identical, including the fact that wifi roms still have a full RIL. It apparently is also still enabled even in wifi s7's. Turning airplane mode on while leaving wifi/bluetooth on (as desired) does in fact affect the system.

Ways of checking: with airplane mode off on mine, the s7 has major issues going into sleep mode. Even with the screen off if you check the battery graph it's still active most of the time. Airplane mode more or less fixes this.

Potential gains: 20-30% or so more life, I've only been testing this for half a day or so but it seems to be draining signifigantly slower in sleep.

Recommendation two: (this one is more valid for the s5 then the s7) Connect the s7 to a pc with the android SDK installed and run 'adb logcat'

The qisda devices are known to have far too much logging enabled and included in stock roms. Virtually all the custom roms for the s5/7 have it removed, but there is a known bug with logging.

If you run logcat so the output is directed to it, afterwards it takes care of another one of the bugs. I have not actually tested this specifically on the s7, but it likely is equally valid as the differences from AOSP (ie the customizations qisda does to the roms) are pretty similar in the s5 and s7.

Potential gains: nearly triple battery life after logcat and avoiding a yet different ril bug on the s5. The s5 can go from potentially 10%/hour to 0.3%/hour due to all/no bugs being active. The s7 MAY be a valid target too, but I havnt actually tested this one on the s7.

Roms used to compare:

S7: Stock 506-wifi

S5: Custom 406 based rom
[Dell Streak 7] khaytsus:
The first one I do, like you said for sleep more than "cell is using battery" nonsense.

The second one I'm confused.... Just run logcat? Or somehow attach logcat to that process, or?

What about disabling those processes? We know there's a ton of Dell processes on the DS 5 and 7 that are generally useless.
[Dell Streak 7] TheManii:
The first one I can definitely confirm works (which is stupid as dell shouldnt let this happen)

I'm getting 27h @ 12% drain with airplane mode

while normally it's approx 1%/hour drain otherwise. If it wasnt such a stupid bug airplane mode should do absolutely nothing.

It's visible on the battery graph as the fact the device rarely ever goes into sleep, it's awake 50% of the time that the screen is off. After turning on airplane mode it's able to to go to sleep fully. It's the way the RIL interacts with the kernel or something really stupid.

I've been studying it over the course of a month, my rom hasnt been modified since the 50x launch and I know for a fact that it's not due to apps since none of them are capable of running in the background (my s7 has very few apps at all installed).

I removed all the unneeded engineering mode/logging apps when I installed my rom so they're not even on the device.

If you compare the S7 and S10 side by side in their battery graphs the S10 can sleep properly and the S7 cant, the s10 also gets 4-5x the S7's battery life even though it's less then double it's battery size.

I dont know for a fact the logcat one is valid on the s7, but just run adb logcat for like 10-20 minutes or so (if it were an s5 you could top off your batt while doing it) and suddenly the batt drain goes down by approx 1-3%/hour on it.

Crosspost on S5 forum discusses this one more, it's equally as stupid but I've been able to study it for about 2 months and can consistantly replicate my results.

The fact the s10 trumps both the s5/7 in batt life cant be a coincidence that dell switched ODMs when they made the s10. The s5/7/venue are all made by Qisda and the s10 is made by PEGATRON and the s5/7/venue suffer from the same battery bugs (as they all share the same codebase)
[Dell Streak 7] TheManii:
The logcat bug doesnt seem to apply to the s7, I've been watching it's batt stats and it might have been fixed in 5xx.

It might have been valid in 3xx but as I have no interest in testing that I cant confirm or deny
[Dell Streak 7] giveen:
A huge fix is a custom kernel that lets you underclock. I run HoneyStreak R8 and I use SetCPU to do this.

Using custom profiles, I do the following:

On Demand profile

Min: 215mhz

Max: 1000mhz (I use to overclock but not anymore)

Profiles:

Charging: 215mhz (Conservative Profile)

Screen off: 215mhz (Conservative Profile)

Under 50% battery: 700mhz (Conservative Profile)

I have my DS7 last me all day long, and thats with like 2-3 hours of wifi, 1-2 hours of video watching, and an hour or so of gaming and then its at like 40-50% battery life left.
[Dell Streak 7] TheManii:
Not really surprised at all, esp after reading the stuff on irc. It's more about undervolting though as even the stock kernel ramps up and down the freq as needed. Though who can say if it does so effectively.

I dont currently use any custom kernels atm though, just a personal preference.

Please, is it There's a way to install Linux or simulate it on Windows phone (like cygwin for Windows)?

Thank you in advance for any answer or idea.

Hello, I have an Ace with a custom rom from Movistar (a mobile operator in Spain). I'd like to have the phone without all of those crapware that the operators install in.

What should I have to do to have a clean firmware? Are there stock roms from Samsung or Google but not from mobile operators? When I search for roms I can only see roms from Orange, Movistar, etc.

Or would it be better to install a custom rom like Cyanogen or so?
[Galaxy Ace S5830 General] alexnm:
Here http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-S5830&r=1#regiona you can find them. Most of them are garbage-free (I believe that Spain is the only country that does that :P). Use the one you like most, there are no big differences.

I really like CM7. But it really battery-hungry.
[Galaxy Ace S5830 General] eyp:
Yes, I knew the site, I'm registered there, but for 2.3.5 version I can't see a Rom for europe or spain without mobile operator dependencies... or could I install any of them although it said France, Russia or another country?

[Galaxy Ace S5830 General] Prawesome:
You dont need to change your firmware just to remove some apps.Why are you trying to catch your nose from round your head while you could easily catch it straight forward (what did i just say :p )

Root your mobile and then use a file manager that has root access like RootExplorer,Super Manager or File manager.

After you open file manager,you might be in sdcard(depends,its based on the file manger you are using).Go up a level and you will see a folder a called apps,delete whatever you want from there.Be careful though,if you accidentally delete system apps,your phone is...GONE :p

BTW,theres no problem with downloading another region's firmware.The only difficulty you MIGHT face is,the default lang. aka the lang. you see when you reboot your phone for the first time after flash,might be different
[Galaxy Ace S5830 General] sdotmouse:
If you like stock firmware I would suggest GingerReal 1.4 or a deodexed/rooted rom from Lovetz' thread. Both in development section.

[Galaxy Ace S5830 General] vinay0708:
yes, u should have root access if u want to del or uninstall system apps.

rooting ur phone is a better option than flashing another rom because ur phone may be locked to a perticular carrier.

(Please feel free to ignore the first two paragraph until the problem).

Problem Starts Here:

I recently bought a Transformer on Black Friday and I must say: I'm certainly pleased. Still, its power are much still concealed and I make plans to destroy that barrier. I wanted to install Ubuntu, but as my research continues, I learned that such was not possible for newer models. This is only possible for devices with serial code "B60-" and under and some "B70-"; however I my code completely split off that trend. Instead, my serial begin with something like "037c7..."

Even with this, I continue on and try some tools such as Frank's tool.

Please, can anyone help me? I would be especially grateful for a guide for such "noobs" like me. I know this is much to ask for and I certainly shall express a gratitude as equally high. Thank you very much for hearing my problem and more than ever if you can assist me.
[Eee Pad Transformer Q&A, Help & Troubleshooting] lilstevie:
you aren't looking at the serial then, but rather looking at something else, ALL asus serial numbers start with a date code which is Bx (will be Cx in a couple of weeks time) have a look at the bottom of the tablet there will be a sticker that has S/N: BxOKASxxxxxx
[Eee Pad Transformer Q&A, Help & Troubleshooting] checkmateyou:

P.S. Is there any other way to run Ubuntu... like not natively or such sorts?
[Tilt, TyTN II, MDA Vario III General] hom.hom:
So this is a pretty familiar problem:

init untracked pid xxxx exited

I places xxxx, because the error doesn't stay at the same number: it goes from 100 all the up to 500, that's when I pull the battery from the phone in order to stop the loop

I am getting this error when I am trying to port IceCreamBread v1.1 from the HTC Wildfire thread, http://xdaforums.com/showthread.php?t=1336611. But I always stumble upon this problem. The rom is posted in the downloadlink:

http://dl.dropbox.com/u/8992815/xda/androidinstall.tar

I am also unable to get information from logcat, since the error occurs before the bootlogo appears (out of my personal experience I noticed that ddms isn't able to detect my phone, before I am able to see the bootscreen:confused:).

I have also used the init.rc from the IceCreamBread v1.1, which I extracted from the boot.img of this build with dsixda's kitchen, but still I have no luck.

In a whim I even extracted the zImage from the IceCreamBread v1.1 build to try to boot this rom, but then, as expected, the phone just reboots right after initialize haret.

So what can I do know? I am able to boot the Official cyanogenmod build for the HTC Wildfire when I perform this method, but with this rom booting results in the aforementioned error
[Tilt, TyTN II, MDA Vario III General] Carlos_Manuel:
I don't have HTC VOGUE/Kaiser! I edit ROMs for JetDroid! So I can not help really much and also I read this post quickly....

"untracked pid xxxx exited" coming because some files is not working maybe you need to change boot.img to other boot.img! I cant unpack/repack boot.img so I can not help with that... JetDroid is using zImage and sometimes some ROMs will not work with zImage which is for ex: CM6... so then it needs other zImage, so try to use HTC Wildfire boot.img if it have it but try to edit it for your device... then check the init.rc and edit it for your device... add the files what it needs to work, etc.

If you replacing one file and it gets the untracked pid xxxx exited, then you need to add the original file back and then maybe works.......

EDIT: it works for me but init.rc needs editing!

init: cannot find setupmodem.sh, leds, etc...

EDIT2: when I use your edited ROM and then sysinit.rc what I renamed to init.rc and added other files to EXT3 on JetDroid then I see odd text and then it's booting and android boot logo stocks many times... so one or more files is not working! ? and it is 2.3.7 ROM! it's just edited to look a like ICS? maybe it is better to edit HTC Vogue/kaiser GB 2.3 ROM and make it look a like ICS ROM?...

:)
[Tilt, TyTN II, MDA Vario III General] hom.hom:
Is there some guide you have found or followed to be a succesfull porter or was it just trail and error for you?

**In your post you adviced to use the boot.img of the device which I was porting, but for example when I use the zImage of the HTC wildfire for my device it simply doesn't boot Haret, but just reboots. So how am I able to edit the zImage: What set-up/programs are you using (I am using windows 7:o)...

The rom I actually want to port is the HTC Hero's Team-ICS rom, but I stumble upon so many problems. And I really am new to porting roms....:p. It's in this thread:

http://xdaforums.com/showthread.php?t=1362062

And this is the boot.img from this rom (I managed to extract it with dsixda's kitchen).

http://dl.dropbox.com/u/8992815/xda/BOOT-EXTRACTED.zip

Fact is that I copy all the, in my eyes appropriate, files from Scoot's gingerbread build, but when I copy these files I am always stuck at the aforementioned init errors. I copy the following files:

http://dl.dropbox.com/u/8992815/xda/porting/Copy/paste.zip

When I copy these files into the original Hero ICS build, in order to get it working on the kaiser, I get that BLOODY init: untracked pid xxxx exited error. The link to the file:

[Tilt, TyTN II, MDA Vario III General] Carlos_Manuel:
OK! :)

I can not edit Android files so I don't really know how can edit zImage...

zImage: on Linux Ubuntu can be edited somehow with terminal and on Windows you need to use Microsoft Visual C+/C++ or something like that and then you need source files!
[Tilt, TyTN II, MDA Vario III General] MaRekRM:
I tried to run your rom from first post but without success. One by one I eliminated init errors by changing files from my working 2.3.7 port, however, at the end i get bootloop with many another errors in logcat... Be honest, at this point I gave up and did not want to waste more time on it.

Using this "copy-paste" port method I had more luck with htc tattoo roms than wildfire

About porting ICS. If I can trust people trying to port AOSP ICS to my second phone(LG) - without recomplilaton kernel and drivers we don't have chance to get this working on kaiser. Too many differences...
[Tilt, TyTN II, MDA Vario III General] PoXFreak:
I concur, there are way too many differences to cope with.

I say this from experience from trying to port the Wildfire's Honeyfire build about 8 months ago (buried in a thread somewhere around here).

Best I achieved is exactly the same point you're at now, with untracked PID errors, even after editing initrd and adding the proper drivers for the Vogue to the build.
[Tilt, TyTN II, MDA Vario III General] PoXFreak:
Has anyone had any luck with this?

What I'm now getting for errors has to do with files being signed (I suppose, have no way to read output).

I get names of modules scrolling across the screen, almost as if the modules in the install don't match the signatures in the kernel modules.
[Tilt, TyTN II, MDA Vario III General] hom.hom:
I have personally come to a point where I am stopped, because of my lack of knowledge. So I think that I can't be a great help to you: I am sorry!:o.

But I think the best thing you can do know, is post the build you got now in an experimental thread (now it is a bit buried under the other posts in this thread). It may attract the attention of a developer with more knowledge, a developer of the same level as DZO:p.

Root and underclock to the 1ghz the processor is supposed to run at. I swear the factory overclock to 1.2ghz does more harm than good.

Use Titanium backup to freeze bloat. Especially Social Locations.

Also, use a black or dark background wherever possible, saves battery life on AMOLED displays.

turn off 4g unless you need it (3g is fast enough for simple things like mail sync and weather); turn off gps; set the display to power saving mode (I'm amazed how bright this display is even at lower levels).

I just posted this in another off-topic thread:

I refuse to charge it with anything other than the supplied motorola charger now. Usually I don't care about chargers. I charge everything I own that's usb powered with my old 1000mA HTC charger. Usually works, but it seems that the motorola charger is 5.1V / 5.2V instead of the 5.0V that most usb ports output. I've noticed a good 5/6 hours' difference from "full" to empty by using chargers other than the motorola one! Takes 2/3 cycles using only the motorola one before I get full life again.

That's from my experience
[Motorola Droid RAZR] milkshed27:
I believe onslaught86 is referring to all the Social Networking bloat in general. There are 6 of them total.

1. Social Location 6.01

2. Social Messaging 2.3.5

3. Social Messaging Service 2.3.5

4. Social Networking 2.3.5

5. Social Sharing 2.3.5

6. Social Status 2.3.5

Social Location 6.01 is the one that may give you problems. Freezing it results in Smart Actions not being able to find new locations. However, if you already have locations saved previous to freezing it, Smart Actions will activate normally.
[Motorola Droid RAZR] Aashrey99:
Would it be OK if I turned social location off from within the social location app(there is an option to turn it off from the app itself using the menu button)? Or do I have to freeze it? I use smart actions extensively but don't use any GPS based profile. So the Social location thing is quite useless to me.
