Undervolting Sensation 4g

I installed Joe RCU kernal and im using cm7, How can i undervolt my sensation for better battery life?
Thanks

System tuner by 3c available in the market.
Matt

yeah i did that but under voltage it says not available.
Mike

Remove any overclocking app you have, if you are using one.
Go to the market, download System Tuner app by a developer named 3c.
Set your clock frequency to whatever you want to by opening the app and going to th tab named Tweaks.
Then, once on the Tweaks tab, click Voltage.
On the bottom left, there will be a button that says "-12.5mV", hit that exactly 7 times. That's the safest voltage that I have seen it can go, altough certain phones can go lower.
To the right, click boot setting and click on re-apply cpu settings at boot, and you're set.
You are now undervolted.

Did you give it Super User permission? Did you also hit the cpu tab before the voltage tab?

I updated superuser and it worked.
Whats a safe undervolting voltage and also how much battery life is going to be improved?

playing with undervolts and it seems the lowest voltage is fixed to 812500
i'm guessing, it's set by kernel, but i wonder, if i can lower it even more?

just flashed the latest bricked kernel on my sensation running arhd 3.6.5

The phone is extremely slow with this kernel. Am i doing something wrong!? What app to use with this kernel to set the speeds and all that?

Ok so I just played with daemon tool and the phone is a lil faster. What settings are h guys running and what governor? Also what's the difference between them?

Help please i dont want to damage my phone running the wrong settings.

Am running min freq. 192000
Max freq on 1536000
Governor smartassV2.

Hi,

Hi,
153 is fine as well.

switch to ondemand governor. and you might want to switch to 1.4r1 bricked kernel for sense 3.0 aka (3.6.x) thats the best version next to 0.91 for sense 3.0

What's the difference between ondemand and smartass?

To my experience smartass is more conservative than ondemand but ondemand is better at performing and conserving energy when not in use. It has a better balance it will know when you max out performance and when not to so battery still lasts long and performance is maximized

Have you tried a reboot? Most of the time, flashing a new ROM/kernel requires a reboot before the phone acts normal.

Most changes are the same... for more specific changes check my Github
flash in recovery
Make a backup before flashing.
FYI: I'm by no means a kernel developer, I'm just compiling because no one else is doing it

Reserved cause yeah

Just curious (and to help out others) - stock based, or CM?
Good work tho! Glad to see some kernel development

Stock based

Oh mate really thanks for this, nice performace. The bury_alem governor still crashing the system, maybe you remove it, the others are ok. The GPU's max frequency is 400 MHz, and when The phone turn on it start as 0 MHz. The rest are OK until now. Thanks again.

As he said for surnia kernel, he has already tested. The overclock in Android isn't like as PC, it's a bit different, if some issues happen, the mobile will heats up a bit, probably freezes, and reboot, then you can flash a more stable kernel. This kernel is working ok, just don't enable the Bury_Allen governor

Hi,
Nice to know that the cpu overclocking is working, and probably gpu problem and the governor problem will be fixed in the next version hopefully. will try it out then. Does it support modified stock MM rom....??

I do not own osprey to test. I made it based on its configs. Therefore, I have released source code for any one want to fix this error.

Man, it's strange, the performance didn't increase, before I flash the kernel I had changed from ext4 to F2fs, Is is can influence in this problem?

can you give direct link to the OC commit of cpu & gpu?

Probably broke some records ;D

Hi I got higher score than that on Optimus R11 kernel,.
Regards
Arindam

If its only pulling 530/1600 on GB3..... its worthless.
I've written extensively and performed hundreds of tests on GB using a half dozen kernels. I've pulled 570+ on single core and 1700 on multi core. Most well built and tuned kernels will average in the 550/1650 range. This Kernel falls flat on its face. As stock Kernels appear to pull about 525-535 single core, and about 1580-1600 multi-core.
The real question is: Does the GPU OC work.
I need some hard numbers to crunch using some graphic benchmarks. Then we'll see.
This is important to know, because I'm about to announce a community project that will crowdsource, and cherry pick the absolute best of the kernels currently in existence. I've long believed that this chip DOES oc, but not as high as 1.8ghz. As squid has shown, you can make it report higher speeds, but not operate at them. 1.4 is provable. Bluspark did 1.6, but theres debate as to whether it actually operated at it. There is NO debate however that the bluspark kernel scored higher than than the 1.4's have, ESPECIALLY on single core benchmarks. I think I've seen as high as 578 with it. This leads me to believe that it *may* be possible to OC the chip to the 1.5 range, before it just stops. Or it *could* be that above 1.4ghz, into the 1.6ghz range there is a disproportional gain in performance due to a)heat, b)inefficiency, or c)both.
The GPU is seriously lacking and without anyone really trying to push the limits until now, its been a mystery as to what it can do. I've seen 650 on the beserk kernel on redmi, but it was plagued by heat with extreme gaming. But users have reported that the 550ish mhz OC was both efficient and effective. So, lets see some real numbers here from some graphics benchmarks.
And to all those that cry and whine, and cry and whine, and yes... cry and whine about battery and heat and poor potty training as a child: go away. You're too far gone to understand that just because its available, you DONT have to use it. What do you guys do when you get into a car thats got 400 horsepower? or use an air conditioner in your home that goes down to 50 degrees? According to your logic, you floor it, until you crash it. Or you die from hypothermia with the latter.
Now..... on to the good stuff. Post your GPU OC vs 400-465mhz scores.

Bugs:
With hal3 active there will be problems with the camera in third-party applications (the default is off)
The "menu" button is not configurable, is the "menu" always called? QRAttached fileFIX_FRAMEWORK.zip (9.27 MB)
There may be problems with the stock camera (if problems with other cameras do not go away) - QRAttached filemarkw-oss-cam.zip (724.45 KB)
It is possible to "stick" the notification of charging / connecting when disconnecting usb / charging (it is treated by resetting)

Setting it right now, it's surely more updated than Hrafninn's last RR rom, mostly for the new kernel with Wi-Fi updated drivers and hotplug, also with optional lowered Cpu freq at 400MHz. Customizations seems to be almost on par with RR, great!
Let's see with Greenify and some blocked alarms/wakelock, what autonomy can provide :fingers-crossed:

Also it have 2.21GHz max freq. that gives antutu over 65k and geekbench 4.500+. But that 400MHz is unusable. Kernel always switching between 652-2.21 GHz and when i tried to set minimum freq to 400MHz my device freeze and rebooted.

It depends on your specific Cpu and other variables, mine, for now seems to be stable...:fingers-crossed:
Anyway I saw there's a huge NETLINK wakelock denying the deepsleep of my device...Now I've deleted all my alarms and wakelock blocked things and from My Android Tools (maybe I was wrong on something that caused the wakelock) and it's fully charged stopped manually at 99%, let's see what happens. The wifi (maybe a little weaker than Miui) and bluetooth scanning are off. Charging was at high speed with original charger and Aukey "big" cable , Led was switched on immediately, but then I've charged with the device off, to speed up the process, and noticed that there's no percentage, only an empty animated icon. Fingerprint is ok, just few issues when trying to unlock on Nova Launcher's home page! I've found that give root to Nova instead of "administrator's privilege" is resolving this issue (Root is needed to use the "lock now button" with Nova).
I've also set the Low Cpu freq at 400MHz and limited the high at 2GHz instead of modified 2.2GHz. Today I'll test also the "equalizer" system app, that yesterday crashed when I opened up from inside Shuttle music app.
I hope to solve the wakelock problem.

Yes it's safe.It's a small overclock and beside that there are mechanisms like cpu throttling and core offline that prevent overheating.Also the rom is not fast because of that, you can barelly notice any improvement from a 10% speed increase.
