Yes! I use cm10, it's android 4.1.2 but maybe i can update to 4.2 already! It's pretty stable, i have overclocked to1.3ghz with a 66vsel(i know, it's very low!) And my batterylife is a day and only one reboot per week!
[LG Nitro HD] X0dus:
**DISCLAIMER** What you do to your phone is your responsibility and this guide will instruct properly but the extra input of a 0, or any number for that matter, can cook your CPU so move forward with caution!!

For now, this is dedicated to those of us still using HO!NO! Full Throttle AND HO!NO! V20F Mod ROM (thomas.raines is working on his LZ oc/uv kernel). The extent to whether the stock uv (undervolt) settings are intact are not entirely sure, but what I do know is with proper undervolting I've been able to get 1d 12hrs out of the stock battery with 1 1/2 screen on time. Let me begin by describing what undervolting/overvolting is:

Dynamic voltage scaling to increase voltage is known as overvolting; dynamic voltage scaling to decrease voltage is known as undervolting. Undervolting is done in order to conserve power, particularly in laptops and other mobile devices, where energy comes from a battery and thus is limited. Overvolting is done in order to increase computer performance, or in rare cases, to increase reliability.

To get the most out of our batteries, uv'n is a key component. All of this is done in Full Throttle under /ect/init.d/99ocvoltcontrol. My tutorial will be done using RE (Root Explorer). It's quite simple, to be honest, and will get you some serious battery life!

Step 1.

Navigate to /ect/init.d/99ocvoltcontrol and set RE to R/W. Hold down the 99ocvoltcontrol file and 'Open in Text Editor'.

Step 2.

You're going to see a lot of 'rubbish', if you will, but the only sets of numbers we worry about are the first two sets in each line. The first number, i.e. 192000 is the clock speed and the 800000 is the current voltage.

What you're going to do from here is select the 800000 and change it to something like 750000, which would result in a -50 uv for that clock speed, which in turn uses less power when in sleep mode or resting at that clock speed.

Example: echo "192000 800000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

subtracting 50 from the 800000

Result: echo "192000 750000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

That's it! Simple, right? You just do that to the remaining clock speeds; adjusting each clock speed to your liking and what works best w/ your phone.

Step 3.

Hit the 'Menu' key on your phone and select 'Save and Exit' and reboot your phone and profit!

Example: My uv settings are as such: -75 from 192Mhz to 1080Mhz; -50 from 1134Mhz to 1566Mhz; and -25 upto 1728Mhz

Keep in mind, in my experience, the higher the clock speed, the more voltage it needs, obviously, so be careful going too low at higher levels.

So try different voltage settings and see what works best for your phone. I've found that going -100 at 192Mhz causes reboots, for example.

[LG Nitro HD] X0dus:
Stock battery w/ the settings I posted in the OP.
[LG Nitro HD] Technocian:
Very helpful and clear instructions, but is the current undervolt set by the Full Throttle ROM not enough?
[LG Nitro HD] X0dus:
That's why I made mention if they're stock voltages or not in FT but if your phone will take lower settings, do it..just be careful! Don't add an extra number. I can't stress that enough! If you set them too low, the worse that will happen, in my experience, is a reboot. Just change the value back to a more stable setting. :D Have fun w/ it!
[LG Nitro HD] Technocian:
I'll give your values a try. Is there a cellphone equivalent to Intel Burn Test or Prime 95? Something to ensure stability would be nice. Also, I never looked into it... but how much more of an undervolt is this compared to stock Full Throttle?
[LG Nitro HD] X0dus:
I use stability test from the play store. The stock FT voltage settings are: #! 800000 825000 825000 850000 850000 875000 875000 900000 900000 925000 950000 975000 975000 1000000 1000000 1025000 1025000 1050000 1075000 1100000 1125000 1150000 1150000 1175000 1200000 1225000 1250000 1275000 1300000 1325500 1350000 1375000 ... So, subtracting 50, 75, or even 100 from any of those in their respective spots will result in such an uv.
[LG Nitro HD] X0dus:
Updated Step 2 to clarify any confusion.

I also changed my UV settings from -75 @ 192Mhz to -100 up to 486Mhz. The max CPU value while in sleep mode is set @ 486Mhz by default so I figured if I can get lower voltage scales in those few than I'm gonna. Passed 6 runs of Stability Test (Play Store).
[LG Nitro HD] hoanglongroyal:
at normal temperature, your phone should be worked ok with UV. the default voltage from stock manufacture make sure it's work on more wide range of environment's condition. when you put it down, it's mean you narrow the range condition. sometime it work ok, normally, sometime will have some issue. take care with your UV value.

---------- Post added at 07:56 PM ---------- Previous post was at 07:48 PM ----------

one more thing, this voltage will feed to one by one each transistors on components of your phone's chip. hope that your change not affect too much to operating of your chip. I guess manufacturer had set limit range value to restrict users who are "tamper limbs" :D
[LG Nitro HD] X0dus:
Bump for HO!NO! V20F Mod ROM. This tutorial is good for his ROM, too, but his is already undervolted atleast -25 already compared to FT v9, fyi.
[LG Nitro HD] NFleck:
Wow, very good guide!

I've always been kind of intimidated by the oltage settings for our phone but your guide has helped me to better understand the settings and files required to edit.

[HTC Rezound] lollixo:
hi I have a sensation xe the sound on the speaker is too low, below average. do have rezound the same issues or is it better?

are there some other problems on rezound that sensation xe doesn't have?

thanks a lot!
[HTC Rezound] jon7701:
From what ive heard the rezound has good external speaker compared to other phones. How loud it can sound can also be determined by how you have your audio set up. EQs can help and also you could get the Sony xLOUD mod which would make your phone louder. I can make mine go pretty loud. ;)
[HTC Rezound] lollixo:
thanks for the answer!

So, can you confirm your satisfaction of sound quality? Have you tried other device with a better sound? (Og droid for example?)

I tried volume+, is EQs better? have you any suggestion for settings?

Is your loudspeaker sound always clear, even when you activate Xloud and similar?
[HTC Rezound] jon7701:
sometimes with the xloud mod it may become distorted if its too high, and i would say the audio quality is pretty good. i would suggest upping the higher frequencies if you want loudness and i dont use any universal eq apps like dsp manager. i use poweramp for my music app.
[HTC Rezound] stkiswr:
I have a Rezound will nils p sense 4 Rom. The speaker is very loud and clear for my usage. Much better than my wife's nexus
[HTC Rezound] lollixo:
thank you! if you are in the shower or in some place with some noise can you hear it good? what about comparition with your ogdroid or other phone?

thank you! if you are in the shower or in some place with some noise can you hear it good?
[HTC Rezound] jon7701:
Well it is about as loud as my OG droid was. I would compare them however my OG droid wont boot anymore. :( and yea with the right settings you should be able too. Sometimes i have to fight over the sound of a TV turned up decently and I can still hear it ok.
[HTC Rezound] stkiswr:
Shower? No problem. Use it all the time
[HTC Rezound] lollixo:
sorry for my insistence I come from Italy and I would buy it in the usa, so I wanna be sure for this choiche. what mean og droid? is it motorola droid 1? i tried to research it on web but i hadn't found nothing with the name "og droid" also in usa...

thanks!
[HTC Rezound] feralicious:
I use the speaker on my Rezound all the time to listen to radio/podcasts and I think it's very good. I can hear it while I'm showering. I'm listening to it now with it on my nightstand a couple feet from me and the volume is less than halfway turned up.
[HTC Rezound] lollixo:
thanks a lot for the answer! have you tried other devices with better or worse speaker? if yes which one?
[HTC Rezound] feralicious:
Can't really compare, this is my first smartphone. Sorry.
[HTC Rezound] lollixo:
anyone else can tell me his opinion? I'd really appreciate. Thank you!
[HTC Rezound] wildstang83:
Honestly, loudness is not an issue. Its the clarity that is an issue at high volume. Understand, HTC tried to do a good thing with the Rezound, but there is pretty much a mix of spending time developing a dual core lte device vs finding better hardware components for what most would consider was the selling point for the Rezound. Sound. Its like they gave up and just said screw it, here is a set of 'beats by dre' instead. Oh well, maybe they will eventually get it right.
[HTC Rezound] lollixo:
thanks a lot for the answer. i believe you, the fact is that I have already the sensation xe so i'm looking for a comparision or just one video where I can check the quality and volume of sound of rezound

thanks!

[Galaxy S III Q&A, Help & Troubleshooting] dikime:
Hey to you, fellow forum members.

Recently I sold my laptop and decided to save a little bit of extra cash instead of buying a new one right away. For all I knew, I already had another personal computer in my pocket - the Galaxy S III. So I hooked it up with the cheapest bluetooth keyboard I could find - believe it or not - Apple's :D

However, I noticed that no matter what I do, I can not get it to type in my native language when using CM10. The keyboard has the additional key layout (not an international edition). When using stock Samsung software everything works fine, even 3rd party apps that support my language work flawlessly. That makes me believe that it's not a "feature" of Samsung's sotck keyboard app but rather something to do with system files. However the files responsible for keyboards (/system/usr/keychars & /system/usr/keylayout) are the same for both CM and stock, so that means the thing I'm looking for is something else, or I'm missing a crucial element.

So... what are the files I have to get from Samsung's stock firmware to make Apple's Wireless Keyboard work?

Thanks :)
[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
I'm having awful battery life with my phone and I have no idea what is causing it. Yesterday I clocked it at 8 hours from full charge to about 10%. I barely used the phone. Very light use.

I already re-flashed several times including clean flashes. I had it in CM9 and now I'm on CM10 but it's still the same. I even tried replacing the battery but, as far as I can tell, I'm getting the same discharge rate. I tried charging it to full charge and then deplete it completely, but it doesn't seem to do any good.

Looking at the battery stats I can't see anything unusual. Screen and Cell standby are usually at the top of the list, with anything below it at pretty low percentages (lower then 10%).

Can this be a hardware issue? Appreciate any help!
[T-Mobile Samsung Galaxy S II SGH-T989] jrocks213:

[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
Thanks for the responses. Unfortunately, CPU Sleeper and Juice Defender are both workarounds rather then solutions.

It seems like there's a fundamental issue here which I'm more interested to solve.
[T-Mobile Samsung Galaxy S II SGH-T989] Grntrenchman:
Get better battery stats and CPU spy. BBS can tell you if something is preventing your phone from sleeping, and CPU spy can show CPU usage over time, by clock speed.
[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
Thanks for the suggestions.

I checked CPU Spy this morning to see how the CPU acted during the night and it seems to be ok. 61% @ Deep Sleep, 34% @ 384MHz and 2% @ 1512MHz. As far as I know this seems normal, but the battery drained from about 93% to about 72% during the night. I only leave WiFi on. Is this a normal drain rate?

It seems like BBS still needs more time before it can generate a report.
[T-Mobile Samsung Galaxy S II SGH-T989] timothylocsin:
+1 on this this is only adding proccess
[T-Mobile Samsung Galaxy S II SGH-T989] Darth:
+2. It would wake my phone 200 times a day on aggressive. Not to mention occasional problems getting data to turn on when I woke phone. Battery seemed better without it.

Try Gsam. To see what apps are waking phone and using battery power. Maybe its the same as BBS...not sure..never tried BBS.

Remember...its not about total battery time...its more about screen on time. I get anywhere from 2 to 3 1/2 hours screen time. And gsam has me at 22 hours average battery life.
[T-Mobile Samsung Galaxy S II SGH-T989] badaphooko01:
I know you said you depleted and recharged, but did you calibrate? That worked for me a while back, now I do it every time I flash a new from which is like once or twice a week.
[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
I thought that the depletion and recharge *is* the calibration. How do I calibrate?
[T-Mobile Samsung Galaxy S II SGH-T989] badaphooko01:
download battery calibration app from the market and follow the directions
[T-Mobile Samsung Galaxy S II SGH-T989] Rod3:
61% deep sleep is not good, or normal. I would look at BBS and focus on partial wakelocks to determine what is keeping your device awake.
[T-Mobile Samsung Galaxy S II SGH-T989] Darth:
Hey....good point! He said very light use....61 percent deep sleep is not light use....or overnight percentage. Something is waking the phone. A lot!
[T-Mobile Samsung Galaxy S II SGH-T989] itsamti:
Hmm, I might be wrong as using Juice Defender from day 1. I see many ppl says JD wont help. Will uninstall and try. Thanks!
[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
I'm kinda having a hard time interpreting BBS. I'd appreciate if you could take a look at the screenshots and maybe see if you notice anything suspicious.

Also, I checked the CPU States in BBS and it is listing better results. 84% @ DeepSleep, 13% @ 384MHz and 1.8% @ 1.51Ghz.
[T-Mobile Samsung Galaxy S II SGH-T989] ToastMan12:
So I just had a major drain. About 40% battery gone after about 3.5 hours of hardly any use.

In Parital Wakelocks, BBS showed NetworkLoacationLocator at the top of the list. But the run time for that is listed for only 4.5 minutes. In the Kernel Wakelock I got "wlan_rx_wake" at the top of the list with a running time of 1h 11m. This seems suspicious to me. Any ideas what the hell is this and how to solve it?
[Samsung Galaxy Nexus] Phoenix128zx:
Hello XDA forum!

I think that this is my first post and I hope that this is the right place to post it. :angel:

I bought a Galaxy Nexus three weeks ago: 16GB Maguro, Takjuxw 4.0 updated to 4.1.1 right after having opened the box.

I am having the same issue as the Nexus 7 owners: when the free storage space gets under 3GB, the write speed goes down to 10kb/s (yes, you are reading it right). Of course the phone becomes unusable if you're using any app that uses a disk cache: Maps, Chrome, Twitter, Facebook, basically almost every app has a cache.

The only way to fix this issue is to factory reset your phone.

Yes, removing your media files to restore the free space is not gonna work (I already tried this and so every Nexus 7 owner did).

My phone is not rooted and it's running a stock firmware. I recently converted my phone from Takjuxw 4.1.1 to Takju 4.2 stock, but the bug was not solved at all by this release (I loaded it up with songs and I had to factory reset it again - just 2,5GB were free).

There is actually a post on Google Forums regarding this issue (sorry, new user, I cannot post links yet) but they only talk about the Nexus 7 while I want to let Google know about the Galaxy Nexus too.

So, dear XDA GNex owners...Are you having a similar issue?

If you DON'T have this issue AND your free space is about 1-2GB:

- What hardware revision do you have? (Maguro? Other?)

- Which version of Android are you running? (4.0.1 - 4.1.1 - 4.1.2 - 4.2 - Other)

- Are you running any particular custom ROM?

- Was your phone NOT filled using the USB cable (eg. your storage is made of film/songs you downloaded using wifi/bluetooth).

- Which operating system are you using? (Maybe MS Win and the OSX app are treated differently by the phone)

- Are you using a firmware mod on a Maguro revision?

If you do have this issue:

- Did you try to clear the Dalvik cache? If so, how? (CWM or stock recovery?)

- Are you using ADW Launcher EX?

- Again, list your hardware revision and OS version - Mine is Maguro, takju 4.2 but I had a takjuxw 4.1.1 when I bought the phone.

- Did you have this issue by rewriting big files a lot of times (example: you have 8GB free and you loaded and then deleted movies with a size of 1,2GB more than 6 times)

The phone has been around for more than a year and it's very strange that nobody had this bug until now, so I want to know about Verizon users too.

I think that this has to be related to the phone internal memory not being TRIM-ed correctly 'cause other Android handsets do not seem to have this bug. Strangely, when you reset the phone, it just works, so it seems file-system related more than TRIM related or factory reset actually uses TRIM to format the partition.

Please, report anything that could be of help to spot what is causing the issue.

I love this phone, if you love it too, post here your experience.

Cheers,

Stefano

- I've got a maguro phone

- running on Kalo v5.0 android version 4.2 (going to update soon to version 5.1^^)

- No specific firmware mod is running at the moment

- No my phone is completly filled using the USB cable

- I'm in use of Windows 7, I don't think this affects your writing on the phone. Maybe try on another computer if you think this can be the problem, and report back?

- No firmware mod on a magura revision in use.

I do hope your problem will be solved soon.

Maguro, stock 4.2 rooted.

The phone does get a little slow when storage gets low, but it's definitely much faster than 10kb/s. My storage gets filled from the camera app by taking videos. I have a Windows PC from which I sometimes transfer some data.

I never had this problem with any version of Android. (Beginning from 4.0.1 ICS)

Hello,

I have posted this on the general q&a already but i think i can get a bit more help here.

I bought a Samsung Galaxy S2 a few days ago.

It is the international version (i9100).

The problem is, i had it rooted and installed cm9 on it.

Then when i tried to make a backup the file was only 16 mb because the sdcard wouldn't mount in cwm recovery.

When i try to mount it manually in cwm it also gives the same error: Error mounting /sdcard!

I already tried like everything, flashing other cwm, other rom, also the original samsung firmware flashed back on gives the same error, another kernel, factory reset and cleaned the cache.

I don't know what i can do now to remount the internal sd card again.

Even when i try to format /sdcard it gives the error.

The only thing i haven't tried is re-partition but i've heard that it will brick your device since it has the bootloader in it which you will also delete.

I am now running cm10 because i thought when you change to cm10 it repartitions automatically. Didn't help either.

I hope someone can get me out of this problem.

The total lack of support teached me...

- difference between baseband, ril and rom

- how to root

- how to install cwm

- how to install roms

- how to switch baseband

- difference between smartflash, nvflash and cwm

- how to use terminal emulator
