Faux, tangent question:

The sensation, amaze, T989, skyrocket, rezound all have the same S3 Snapdragon CPU. Did your experience gained on the Sensation Kernel transfer over when you work on these other similar devices or each device is its own new challenge?
[T-Mobile Samsung Galaxy S II SGH-T989] darkamikaze:
Mm is there anyway I can drop the lowest clock to 192mhz? For some reason when I do after I exit system tuner it bumps it back to 384..

And this isn't the system tuner glitch where both min and Max would read your Max voltage.

And what is sec-battery-adc?

yeah SGS2 (Hercules, Skyrocket) were pretty straight forward, mostly copy and paste :D Not much different from Sensation. Sensation was tons harder because HTC tend to "customize" their crap away from CAF baseline where as Samsung is pretty much CAF baseline with minimal changes (which is really the correct way IMHO).

Amaze was a total screwball by HTC, they barely unlocked the boot loader (still with security bit set, so has to use a special app or use a PC to load kernel), then WiFi driver is customized and under Apache license (not the usual GPL v2) so no access to WiFi source. I had to do a hack around without being able to compile my own WiFi module which severely limited the kernel haxing in general.

Is 11-14 hrs battery normal with underclock of 1.4ghz and uv -80?
[T-Mobile Samsung Galaxy S II SGH-T989] armyofbear136:
Depends how you use your phone, most people only see 10 hours or so and if you're getting 11-14 hours with use that's pretty darn good. If that's not enough you could really get some extra hours out of your device by shutting off data for periods when you're not using the phone, it zapps the majority of the battery, and you will still receive text and calls.
[T-Mobile Samsung Galaxy S II SGH-T989] TheSeanTeam:
I don't know if it was a bad flash or what... but 9u was pretty bad for me. No problems for the first 10 or so hours, but after that I got tons of sleeps of death and random reboots. It's been a loooooong time since I got a SoD. Can't even remember what ROM/kernel which gave me those issues.

Anyway, went back to 7u and all was fine.

I was using the UV script and I even used the normal script to see if that was the issue, but no dice.

Think it was a bad flash?

---------- Post added at 09:28 AM ---------- Previous post was at 09:23 AM ----------

I don't think there is a normal. It all depends on what you use your phone for, for how long, and how's your signal strength. I think those factors are much more important than underclocks/undervolts.

11-14 might be good or normal for someone, but for me, I like to get 17+ hours if possible.

Guys I've been test running the synergy kernel... It does not have better battery life than faux's running dewizzed. Can't say about other roms.

I roughly ran the phones about the same uv and underclock speeds (altered gideon's script.) Faux is much better when phone is actually in use. However, synergy seems to have the same or a bit better idle drain.

The reason is on reboot, the kernel is going to hit whatever the kernel is clocked at momentarily until the script/CPU app is granted permissions to alter your speed. Just reset timers in CPU spy after say a min and you will see correct CPU speed

Battery Stuck v009

Hey folks, fantastic battery life in this kernel, but I've noticed every other day the battery stays stuck at 100% until I reboot, after a night of charging.

Had 009u on 1.35Ghz and -87.5mv undervolt using GideonX's script and at one point, (you really gotta let the kernel settle) I would get 24-30 hours of mid usage.
[T-Mobile Samsung Galaxy S II SGH-T989] kiingJ:
WOW! thanks for the quick response. Thats pretty impressive to have that many hours. I am not using the G script but instead using fauxclock. I have it set to 1.674 ghz/384ghz with -37.2 UV. Would you recommend lowering the voltage a little bit more? Im just worried for reboot and instability.

BTW, how big is the difference if I underclock from 1.674 to maybe 1.512ghz...is it noticeable? if not really, I rather tweak it down to safe even more battery!

Thank you so much, your help is greatly appreciated!!!
[T-Mobile Samsung Galaxy S II SGH-T989] GreggoryD502:
You can try to lower the voltage more. Make sure you dont check the set on boot option until your sure your phone can handle it. I have my phone clocked at 1.08 and its smooth as all get out. I would bet that unless your playing really demmanding games you wont notice a difference.
[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
Going that low was really pushing it for me. when i was -75mv i got several reboots and hot boots but I figured what the heck and pushed to -87.5mv and it survived. Survived quite well.

Finding that sweet spot of speed and undervoltage can be really frustrating and time consuming though. I'd maybe underclock these kernels to stock or lower (1.35 - 1.512GHz) and run with that.

If you use Gideon's Script (he clocks it to 918MHz/-75mv/ondemand) and you're confident to open his file and tweak it some, you can go without using FauxClock. Just makes things cleaner.

This 009u kernel has 2d and 3d GPU clocked to full always so tuning your CPU from 1.7 to even 1.2GHz is pretty negligible. Scrolling should remain smooth and fluid because the GPUs are fully clocked. Still, undervolting too crazily will reboot you and the more I undervolt, the more stutter seem to surface.
[T-Mobile Samsung Galaxy S II SGH-T989] TheSeanTeam:
Weird. Redownloaded and flashed 9m and got another SoD. Gonna go down to 7u for now. So strange.
[T-Mobile Samsung Galaxy S II SGH-T989] kiingJ:
mettleh3d,

thank you for all your help. your information has been superb! now knowing that the gpu is always clocked at max...i will go ahead and lower the CPU. and yes i did notice stutters when i UV to -50...seems stable at -37.5.

Thank you mettleh3d, you are super awesome!

One last question: is there an app or a way to see how much I undervolted?

I see under fauxclock that its already undervolted but i want to make sure with another app to monitor it. TIA!
[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
I believe so. Goto market and download "Terminal Emulator"

Copy paste this in there.

cat /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

and it spit out what your current voltages are. For sake of comparison here's mine UV'd by 50mv.
[T-Mobile Samsung Galaxy S II SGH-T989] jay661972:
Or open terminal emulator, type su enter and type cpuinfo.sh enter.
[T-Mobile Samsung Galaxy S II SGH-T989] kiingJ:
Im such a noob. How do we read all thos VDD numbers? lol
[T-Mobile Samsung Galaxy S II SGH-T989] abrown0809:
Thanks a lot faux! This is a great kernel.
[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
Basically you match your current clock to the voltage.

without outside influence, 1.728GHz is 1300mv or something. Undervolting across the board by -50mv brings it down to 1250mv and so on for each clock speed as shown in my screenshot.

so if youve undervolted by -37.5, your speeds should be 1.728 12650000 or something.

They don't stick? You should try to go back to recovery and wipe cache, dalvik and re-flash again.

If that doesn't work, i've done this before, flash a stock kernel (romanbb made one before, I don't recall where it is right now), reboot, recovery, flash faux123 again and your CPU tuning app "should" stick.

Or use a script.

I tried both aDownloader & tTorrent, they all crashed in the middle of the download. I've attached the "last_kmsg", could someone take a look and tell me if this is it tells anything meaningful? If not, what could possibly have caused this?

[T-Mobile Samsung Galaxy S II SGH-T989] shinew:
ah no wonder it looked so short and I didn't see any error or panic in it... :p

So I'm not entirely sure if it's 009's fault, but I've reverted back to 007r2, and downloaded a 1.6GB torrent and try to make the phone crash by using other apps, putting the screen off, etc... but no crashes...

I would also like to report that after few days of use in identical environment, and periodically checking the log for power drain during idle, 009(both u & m) also gave me worse battery life, it swings from 50mAh-80mAh for idling, while 007 draws 17mAh-40mAh.

Anyway, so this is my observation. I use everything at stock settings except the ROM is debloated and your kernel of course :D. thanks!
[T-Mobile Samsung Galaxy S II SGH-T989] faux123:

[T-Mobile Samsung Galaxy S II SGH-T989] shinew:
That was the "complete" file from the phone, could it have been truncated by itself during the dump?

I just checked the last_kmsg again on my phone, and it has been updated! I thought the last_kmsg was generated only when the phone crashes? and It hasn't crashed since last time I uploaded the last_kmsg...:confused: Anyhow, I've attached the new one to this post, not sure if it means anything though.

thanks! :)
[T-Mobile Samsung Galaxy S II SGH-T989] shinew:
Just out curiosity, I tried 009m again to see if I could duplicate the crash and get a complete last_kmsg dump, the result was the same, it crashed and dumped a turncated last_kmsg. I know it's probably not much use but I've attached the new last_kmsg anyway.

So I'm 90% sure that it's 009 related issue, as I tried re-downloading the same file after flashing back to 007m and I could not crash the phone, the phone just slows down when using other apps and sometimes feel abit jerky but no crash. With 009m, the crash seem to be more likely to happen when accessing the internal SD card using something like Gallery while downloading to it, but not always as it crashed before while it was not doing anything else

Again, they have been tested under the same condition, using WIFI, tTorrent Pro(or aDownloader), downloading speed was about 1.5MB-2.5MB/sec.
