I would just like to know from people who regularly listen to music about the drain they get while doing so because I would like to see if I could tweak my phone further to reduce power consumption. If you could give me percentage per hour along with the bit rate of your music averaged out it would be really helpful (I know there are many other factors but if I specify too many then it would just not the be helpful) . I'll start of, 5-6% drain per hour & average bit rate 128kbps.

[Galaxy S II Q&A, Help & Troubleshooting] egps2:
Hi I usually drain about 2-5% battery per hour of music but this always includes about 5 minutes screen on time to browse music :)

To anyone with freeze issue: please try ininstalling better battery stats as that has fixed the issue for me personally! Running DXLPB and siyah 3.3.3b for now.

To person above: I wouldn't hold my breath on jelly bean support for the immediate future but I hope we get official 4.1 on our phones with released Samsung sources to help out GM!

CFS tweaks: I don't care about benchmarks but does anyone know a bit more about the pros and cons of the CFS options we have available? I know Thunderbolt! is developed by a talented XDA member but I would appreciate a link to any posts discussing their differences!

Thanks guys :)
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Actually, it's not so much a BetterBatteryStats issue. It's due to how BBS calls su. The recent update for ChainsDD's superuser somehow broke the BBS call with the new 3.3.2 kernel.

Unsure about this, but you can try SuperSU and see if it also fixes it.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
I have never been able to get such good results. Always in the 5-6% range. What config are you running on?

I for one think he would get it done as soon as he would have updated the s3 kernel. Gm wouldn't leave us hang like that. He still continues to support this kernel but just not like before so I would ask you to hold your breath:p
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Music only/screen off most of the time = 2-3% per hr, Poweramp, CM9/Siyah. Not sure how bitrate figures into things, but 90% of music on the phone is either FLAC or 320kbps MP3 (about 60%/30%, other 10% is <320kbps MP3).
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
I asked for bit rate because I was going by the logic that the higher the bit rate, more will be the load on the processor because there will obviously be differences in mp3 at 128kbps & flac or mp3 at 320 because more info is being processed & pushed but then again my reasoning could be wrong. Could I have your settings to compare to what I have?
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Ahhh OK, fair enough. Yep:-

CM9 05/06 nightly, Siyah 3.2.3/battery profile with a few ExTweaks adjustments; Ondemand/Sio, 100-800. What else ? ;-)
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
I'm assuming you would have uv the cpu as well. I would need to have a look at the battery profile in ExTweaks now. Tweaked the governor or stock?
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Yeah sorry, -50mV. No tweaks to the governor. Just a few tweaks to CPU/GPU settings, but these don't make enormous (say a couple of % per hr) difference to drain.

I figure together they probably only make a little difference with 'light' usage (maybe 1% hr tops, and they probably make more of a difference as usage increases), tho someone like Pika or Droidphile would be able to give you a better idea than me of how much difference these little changes make to drain.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Yeah shouldn't cause a major difference in consumption besides drain is highly subjective based on individual configurations & apps. Anyway thanks for you replies. I'm outta thanks for today but I'll hit to up tomorrow.

Could someone clarify what is the "soundgasm" feature? If it's something like Voodoo Louder (headphone amplification - in decibels) I think I'm going to have an soundgasm!:p I'm waiting for this to come to Siyah for a long time - cannot buy Voodoo Louder from my country.
[Galaxy S II Q&A, Help & Troubleshooting] maciekbe:
Hi,

I'm an audio professional.

Decoding compressed audio you end up with standard CD-like data stream, but higher compression requires more processing. Usually less compression means less processing. This way 320bps is lighter on CPU than 128bps. You can observe it easily on a PC. Compressing to lower bitrate takes longer. On the other hand, with lower stream, there is less memory reading. I don't know what final power drain will be.

I didn't know that. Like I said I just guessed that it would be the opposite but this does makes sense. Thanks for the info.

[Galaxy S II Q&A, Help & Troubleshooting] maciekbe:
The same is with video stream. It's always choice between storage (volume and speed) vs. processing power. The less compression, the less processing.

Just flashed 3.3.3c. Working good for now.

Loving the soundgasm feature. Has this been recently developed? Why wasn't it there earlier?

Now if anybody can just guide me to a link to understand the 'CFS TWEAKS' and 'MAX CPU LOCK' features in ExTweaks (a noob proof guide), it would be awesome!! :victory:
[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
the mc1n2 (yamaha) chip in sgs2 had this potential since the beginning and there were some people using that either in their kernels or in their apps.

I did not change the kernel code for that, extweaks uses the kmemhelper binary that I have coded to make some changes on kernel variables. so, anyone can use that feature. they just need kmemhelper and the script in /res/customconfig/action/soundgasm_hp.

I will be a little busy this week but I will publish an app for that and even stock or other kernel users will enjoy it.

CFS tweaks are just 3 different settings for the system scheduler (something like the governors, but internally used for the system processes. The settings each have a different balance, so it's just a matter of trying them out

(they differ only in UI responsiveness levels) (take into account, more responsive,more battery and vice versa)

MAX CPU LOCK is a way to block pegasusq from using both/more cores, (just as hotplug_lock). Setting it to single-core will tell pegasus to use only one-core (which is kind of senseless, 'cause opting for pegasus, you'd want it to use both on the SGS2).

It's more of use on the S3, which has 4 cores, and you would like to tell pegasus to use only 3 or 2 instead of all 4.

EDIT: just had a look at the load profiling with the different CFS tweaks

compared to samsung default : linux -> leans towards a bit more battery friendly ThunderBolt!-> more responsiveness

but I'll have to give it a duration test to be sure....

Hi guys,

A friend of mine installed this fantastic kernel version 3.3.3c flashing it from CWM but he's got a problem: after quitting some apps (like the game fruit ninja and some other apps) a message begin popping out and the message is "shell has been granted superuser permission"..if you go look in the log you can see 200 notification of shell that has been granted su permission..we tried to use supersu instead of superuser, the notification dissappeared but the phone is slooooow and he had to reboot so this mean that even if I don't get notification the shell is still active in the background and slows down the phone..now, I don't know how to deal with it and I thought that this is the best place to ask!he has an italian stock unbranded LPF ics firmware on the phone..maybe he has to move to LPG? Thank you all :)
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
did you see any name (of the script) which is getting this permission granted?

Is your friend using Superuser 3.2rc1??? Might be a Superuser issue. See ChainsDD's tweets (part 1, part 2 & part 3) about this matter, and get your friend to contact ChainsDD so that he can narrow down the issue.

Uninstall better battery stats. The shell script is the dumpsys alarm routine gone wild with the updated su binary.
[Galaxy S II Q&A, Help & Troubleshooting] 7HUND3R:
the script is named "shell" and the message is "shell has been granted superuser permission"

What do you mean with uninstall better battery stats? XD I need to uninstall superuser and leave just supersu because the the superuser binary is making the shell going wild? Or I need to recalibrate the battery by wiping battery stats when is 100 % loaded?

My friend is using superuser 3.1.3..we only do stable update and trying to avoid beta, nightly and RCs ones!
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
You have the app called better battery stats right? Uninstall that app.
[Galaxy S II Q&A, Help & Troubleshooting] 7HUND3R:
I don't think he's got this app, I can ask him! if it is not the problem what about uninstall superuser and leave just supersu? it's strange because the shell start working when he closes some apps or play some game but not when he uses apps that need root permissions!

...that would probably solve it "uninstall superuser and leave just supersu"

Su is working fine for me with 3.3.3c. I updated the binary just to be doubly sure as I always do whenever I flash a kernel (even if Su doesn't need updating), and it hasn't missed a beat yet.
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Su isn't the issue. It was how BBS was calling dumpsys alarm in the new su binary that's causing the freezes/SODs etc in the 3.3.3 Siyah versions.

You can call it a culmination of problems.

If you are using siyah kernel, then you should used superuser not superSU. You just need to removed root with auto-install root enabled in extweats as shown and reboot the phone. This will give you a proper root and made the phone stabled.

[Galaxy S II Q&A, Help & Troubleshooting] 7HUND3R:
When I installed the kernel I had superuser installed by the kernel because the firmware was perfectly stock without root..maybe is the fact that I update via market to 3.1.3 that cause the issue? the strange think is that the programs that need supermissions work fine! now I have supersu installed, just supersu.. I removed superuser and do the wipe dalvik and cache partition..the phone seems to be stable now but when, for example, I quit fruit ninja it takes 15 seconds to stabilize before you can normally use the phone! if it need to be rebooted because I freezes or get stuck I try to install it via extweak as you suggest! thank you!

@pikachu01: I get a lot of network_stats wakelocks which just started to happen quite recently. After charging my phone the wakelock beings & its not a constant wakelock, it keeps appearing intermittently through the time the phone is in deep sleep at fixed intervals. Posted it on the bbs thread but no one including chamonix was able to help me. Do you know what cause that wakelock? I can pm you my dump file. Sorry for the OT guys but this is just getting on my nerves & its starting to really piss me off:mad:

Update to the latest version. That should get rid of all your problems. Always update to the latest version before reporting bugs to see if the bug exists on that version also.

Its a Samsung RIL crash that happens ever now & then cause the RIL itself is just horribly coded. Try replacing your modem to see if it helps reduce the frequency of the crashes but don't expect the problem to go away.
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Can you dump your BBS log, a logcat and demsg dump as well as a 2minute wireshark dump while your phone is connected to the network that produces the wakelocks?
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Is a demsg dump in /proc cause I don't know where I would get that? Not connected to any network when this happens. I use only my standard data connection for Internet, and no wifi at all. When the phone's screen is off all data connections are off. From what I've been reading a network_stats wakelock is only held while collecting and

recording statistics from the kernel, and it should only be held for a

short period of time(source). Maybe the info on that page could help you to help me cause I'm not completely clear on what has to be done. TIA
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
demsg dump can be obtained using OS Monitor or just type "demsg" without the quotes in Terminal Emulator.

Yes, the BBS dump and logcat should suffice.

If data is turned off while the phone is off, you can't get any wireshark dumps.

Just for reference sake, you can dump a wireshark dump while your data is on (screen is on too and idling) to see what data is accessing your network as partial wakelocks can happen when your screen is on actually.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Alright I'll do that & give it to you tomorrow. I know about wireshark & I'll keep what you said in mind but I never keep data on when screen is off so there should be no chance of what you said happening. The screen is never on when the partial wakelock happens as you can see from my screenshot of last night.
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:

I also started seeing this network stats wakelock from around the 2nd week of June. That's why I moved back to an early June build of CM9 & Siyah 3.2.3 (I'm now running Siyah 3.3.3c & that 05/06 CM9 build & seems to still be OK).

I tried everything to try & fix it/nail it down, even did a completely clean install of latest CM9 (tried it with just CM9 stock kernel for a bit; it still happened), tried it with different versions of Siyah, still happened no matter what I did.

Only thing that fixed it for me was going back to that build of CM9/earlier build of Siyah.

And as I'm not getting the problem with the latest build of Siyah, I'm not sure it was a Siyah problem, more a ROM issue. My sneaking suspicion is the radio is causing the phone to poll or sends stats/info to/from the nearest cell tower more than it should be, causing the wakelock (sends info/request to tower - waits for response causing wakelock ? And does this constantly but intermittently)

I'm going to try latest CM9 nightly in a few days/over the weekend to see if it's still an issue, but I doubt it's on the Siyah side given I haven't seen the problem at all over the past day since I flashed 3.3.3c.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Hmm..That sounds likely. I can confirm that it isn't a siyah issue because I flashed fluxi as well & the issue was present. I attributed it to the fact that it maybe some app that causing it like a monitoring app due to the very nature of the wakelock but after freezing apps in that category the wakelock still persisted. Now I'm inclined to believe that it is the rom itself because I've tried pretty much everything but I haven't been able to hit the nail on the head but what's surprising me is that nobody in the cm9 thread seems to be reporting such an issue so it's leading me to believe that it maybe a kernel & rom combo causing the issue but again maybe people use this combination & again no one seems to be reporting this issue. The time frame which you have specified seem to be consistent with the time the wakelock cropped up on my phone as well. The suspicion you have might be related to that but wouldn't that be a network location wakelock? The funny thing is that there is no consistency to the wakelock. Sometimes it's normal but most of the time it's there. Based in observations I feel that it doesn't appear if you do a reboot right before you unplug your phone from the charger but I haven't actually tested this. After searching the web [URL="https://groups.google.com/forum/?fromgroups]this[/URL] is closest I could get to an informative web page which could help me & now us.

Hi guys

After I flashed 3.3.3c l recognized strange kernel wakelock "main" which l have never had before on any kernel neither Siyah. It seems this wakelock is active all the time when phone is awaken. However it's nothing noticable in partial kernels section. I'm not sure how does it influence battery draining - I am still testing. Has anyone noticed this? Can't find on xda any description what causes it.

If this has been discussed before, I will accept a light slap on the wrist, but here goes

I have 2 cellular contracts - one is a voice and data contract and the other is only a data contract. The cost of data is a huge amount cheaper than the one on my normal voice contract and I want to use the data from the data contract to save costs. I have a USB Modem with the data contract and was wondering if I can connect it via OTG to use the USB modem for a data connection. My carrier can not link the 2 accounts and I can not swop sim cards all the time (not practical).

(1) Does this kernel have the modules to enable me to use an external USB modem?

(2) What script would I need to enable communication between the USB modem and the phone? (this might be a question for another thread)

Have those wakelocks too, as of yesterday...(more than usual battery drain overnight) and the only variable that has changed is 3.3.3c (or one of it's settings CFS tweak ; other than that same roms, same other settings).

[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
I'm getting the impression those wakelocks also exists on 3.2.7.1

I can remember there was a recent update of Google maps and stuff in the period MistahBungle mentioned, and having updated it on my side, I think this is what causing it (at least on my device) (location update through mobile network services). Disabling google's location services in android settings gave me a wakelock-free profile. Maybe Google goofed up or intensified their tracking of our movements :cyclops:

Going back to 3.3.3.c now to confirm and test battery life some more.....
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Interesting. I've always had location services disabled & I have Maps frozen (tho now that you mention it, I do remember that update). So I'm still not sure what's causing it. As I said, the closest I could get to nailing it was something in CM9 after around 5 June. On any build before that, seems to be fine for me. With any build of Siyah.

Strange.
