I notice the default voltages for all Clock speeds up to and including 486MHz is 925mV. Does it follow that setting your lowest speed to 486MHz will not affect battery performance anymore than the freqs below that?

Also, I see that some people are citing freqs above 1512MHz. I'm not able to run the slider up past 1512 MHz. I'm sure I'm missing something, so what is it?

I apologize if these are dumb questions..

Thanks.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] CamFlawless:
To answer your second question, you must first enable OC steps by checking the box in the option above the MHz scales. ;)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyHeart:
Power consumption is a function of both potential and frequency.

Yes, you are missing somthing - under general, there is an option labeled "Enable OC Steps".
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jpride:
Okay, thanks for the tip on the OC steps. Should have read the text under the header on that option.

What is the function betwixt those two things? In short?

Thanks.

Ur first question yes btw. I run at 486 for that reason. A tip i got from entropy512 on my sgs2 days is that why run lower frequencies that use as much power as a higher frequency when u can get better performance for that battery life

It works for me like a charm... Never had to worry about wake up lag or anything

hi, i tried to flash KT747-Kernel-AOSP-JB-MR1-ATT-01-10-2013.zip with latest task650 rom and it wont get past Samsung logo, it keeps reboot.

i am not sure if its a right kernel for task650 rom. would aosp kernel 4.1 work on latest task650? di

did try wipe/cache after or before aosp kernel, its same issue. where can i find a stock kernel? i cant find the stock kernel in this forums.

thanks
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyHeart:
You're very welcome for the tip. (Just the tip ;))

I've never seen the formula myself, but I've been told that it's a square function regarding frequency.

So, I imagine it's something like this...

Power ∝ (Potential Difference)(Frequency)²

EDIT: Just came across this which suggests that it's the other way around [Power ∝ (Potential Difference)²(Frequency)]. Which forum should I believe?

Either way, the takeaway is that power consumption depends on frequency AND voltage. So using a higher frequency at the same voltage will, indeed, increase power consumption.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] clipsruck:
Just curious if anyone has had issues with DLNA on the latest tw kernel? My screen did this for about half an hour.

I haven't done a ton of research yet. I searched though and didn't see anything useful. It may be something I've done, but I wanted to ask before I start wiping sh*t.

That is definitely the right one, I am running task's rom with that version and everything is working great. If you need to revert back and don't have a nandroid, task's underwear kernel (the one that comes with that rom) is available in the OP of that thread. Otherwise, I would suggest re downloading this kernel and install, wipe cache, wipe dalvik, fix permissions. Hope that helps.

Hey,

I just installed tasks aokp latest with this latest kernel, I have uv by -75, using ktoonservative and noop governor..

but I am losing battery alot!! With stock android, no apps installed..

Can someone suggest better governors?

Thanks, any other suggested governors for saving battery? Is there anything better than noop?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ktoonsez:
My governor is the best by far, and noop is a good choice for battery.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] CamFlawless:
Ktoonservative is the best for battery and performance IMO, and it's so incredibly responsive. :D

As for I/O schedulers, try ROW. It is what KT recommends. :good:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyHeart:
The recent trend is toward ROW. Not sure it'll help battery at all.

Why are you so quick to blame scheds/govs for battery use? It's more likely due to: screen brightness, signal quality, etc.

Also, you said you "just installed" a new ROM and kernel. Give it a few charge cycles before judging.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ktoonsez:
ROW is NOT good for battery, it is a great performer but does cost some battery.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] awaisuk:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ktoonsez:
yoyo should be OFF (0) to save battery.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ktoonsez:
Are you refering to the "cpu_down_block_cycles"? If so, a cycle is every 45 milliseconds (the value of "sampling_rate") so putting a 44 in "cpu_down_block_cycles" produces a blockage of hotplugging for 2 seconds to help yoyo effect.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ktoonsez:
That is the "SMD Packet Driver" for your modem, you might have a week signal or your phone is downloading files/data.

Im getting weird battery readings

My phone has been unplugged for about 4hrs now and its already down to 40%. Less than an hour screen on. 45mins or so.

Have Ktoon/row w/yoyo and some UV (-30 i believe). I just started using these settings. I typically stay with Ktoon/cfq no UV

Weird thing is that my phone battery reading will actually go up at some points. Like earlier I looked and it was shockingly at 70%. 10 minutes later it's back to 90%. And then another drop.

Idk what's going on, but it's been like this for a while now no matter the kernel. CM10 or this one.

I guess my understanding of "yoyo" is wrong. I thought this was what allowed the kernel I guess to turn one of the CPU cores off every so often thus saving battery. Judging by this post it appears that I'm misunderstanding it.

Sent from uber hacked GS3
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Urinophoria:
Basically, "normal" behavior in 4.2 is to continually switch the second core on and off every 1-2 second which KT described as yoyoing. He modified the kernel to suppress that, making the second core less likely to engage for no reason, but some people had problems with lag. So he put the yoyo "switch" in, so that if you experience lag with "yoyo" suppressed, you could turn it on.

This fixed some people's lag at the (possible) expense of battery, although I've seen a few people claim to be running with yoyo on, to no detriment.

Looking forward on flashing this Kernel (4.2) to the current install of Task & Ktoonsez JB 4.2 ROM, so far it is smooth except for the obvious WiFi Tether not working, I would like to flash this kernel in order to have the option to lower the notifications vibration intensity since the stock kernel of Task & Ktoonsez AOKP ROM does not have the option to lower it.

As far as the updated drivers, is it very difficult to restore to the stock ones if later on I decide to sell my phone?

Also are there any Flaws regarding to this Kernel (4.2) and the Task & Ktoonsez AOKP ROM?

Okay, I have run into a little brick wall here and I'm not particularly sure what I did wrong while installing this custom kernel.

I am running a stock touchwiz 4.1.1 rooted ROGERS ROM.

I rebooted into cwmr and chose install zip from SD card. I installed this kernel.

After installation, I wiped cache/dalvik/fix permissions.

I rebooted and managed to get to the lockscreen.

Now my phone sits at the lockscreen for about a second, then reboots immediately to the spinning samsung logo (the one with the sound). It has been doing this for the past 10 minutes or so. I am still able to boot into cwmr without any issues whatsoever. Is there anything I can do to get myself out of this without flashing back to stock again?

Would a factory reset do any harm? I really don't feel like flashing my device over again today since I'm really busy, but if it's my only option I will.

Edit: okay, so I re-wiped my cache/dalvik/permissions again after being in that boot loop for about 10 minutes. After "android is upgrading" It's still in a boot loop.

Oh I almost forgot to mention: I have done a cwm backup before I installed this custom kernel just in case. Would I be able to restore from that?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyHeart:
Restore the backup that you made immediately before flashing the kernel.

OR

Flash a kernel which you know works with your ROM - if it's not already on your device, you'll need to put it on a micro SD.

OR

Backup, flash to stock, download a kernel which works with your ROM, restore backup, install working kernel.

I'm sure there are many other options, but these were the first few that came to mind.

P.S. Which kernel did you install?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] baconatorXVI:
A factory reset delete all your apps like things from the market and your settings, but it will return you to stock kernel.

Try a few things, go back to cwm and try following the kernel flashing steps again, if that doesn't work..

When you say stock rooted does that mean you flashed a stock rooted Rom.zip file through cwm? If you flashed your Rom through cwm you can always re flash the rom.zip to get the stock kernel back and it won't delete anything.

If you decide to factory reset you can use cwm to make a nandroid backup, then use titanium backup pro to extract your backed up apps from the nandroid. This won't remove your cwm.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Alexander2013:
I installed the JB TW ATT kernel. This one here: http://www.mediafire.com/?etk37v5590266cv

I am going to restore from my backup and see where this takes me first. Since I can't really boot into Android, I can't really connect my device to my PC and use Odin3, but I can still use my sd card and put files on that if needed.

Edit: Alright the restore worked, just as I thought. Now I am still wanting to install this kernel, but I fear I will run into the same problem as I have before. Not that it's a really big deal, everything is just the way that I left it with the restore, but I would really enjoy using the features of this custom kernel. Any sort of insight would be nice.

For those of you wondering which ROM I have flashed, I'm using this one provided here: http://xdaforums.com/showthread.php?t=1739426

Odin uses download mode. Like recovery, download can be accessed by booting with a button combination.

Not sure how it slipped my mind, but baconator's idea is best - just flash the ROM again. This will install the original, working kernel.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Alexander2013:
Sorry, I edited the post above. I have already successfully recovered. Wifi, bluetooth data, everything is still working now. I just don't have the KT747 kernel installed, which is something that I would love to have installed.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] haveagr8day:
Make sure you wipe cache, dalvik, and fix permissions after flashing the kernel. All I can suggest would be to try to flash the kernel again and see if anything changes, otherwise you can go back to the underwear kernel included with task's rom (download in the OP of his thread), backup your stuff, then full wipe and update the rom to the latest version and try again. It definitely works fine, I have been using the kernel with task's rom since December without any major issues. Good luck.

Is there some kind of thermal control on the CPU that changes the minimum CPU speed in this kernel? Trickster mod keeps showing that my minimum CPU speed is 1.026 GHz even though CPU spy and ktweaker say it is 384 MHz.

I'm asking this because the dev of Trickster mod said that the reason my minimum CPU speed is misrepresented in his app is because of this thermal control.

The dev is very popular in the galaxy nexus section on xda so his credibility should not be an issue.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyHeart:
Sounds counter-intuitive.

Thermal control kicks in when the CPU gets too hot.

Heat is proportional to power, which increases with frequency and voltage.

Higher frequency means more heat.

Why would thermal control force your CPU to create more heat?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] crazililazn:
That's what I thought too. Plus, KTweaker and CPU Spy seems to show the correct minimum CPU frequency... But he insists that it is Qualcomm's thermal control.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] 1weener:
Maybe he means that his app doesn't read the MHz properly because of Qualcomm's TC?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] crazililazn:
Nah, he's saying that the reason why my minimum CPU frequency is being changed to 1.026 Ghz is because of the thermal control and there is nothing wrong with his app and how it displays the minimum CPU frequency.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] drinfernoo:
I keep forgetting to try permissions...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Medlock87:
Either way, this is what ktweaker is for. Choose "Lock Frequencies" so that other apps can't change your cpu speed. I'll also say that the thermal throttling argument doesn't make sense either unless it was turning DOWN the MAXIMUM speed, not cranking up the minimum.. :eek: Find a better app imo.
