Voltage control settings

[goldentuna]

I'm having real battery drain with Network Data turned on & looking for any ideas or solutions.

I'm running immuts 100 on the debloat ROM with stock ED01 radio.

I've always thought it was the poor phone reception that was draining my battery, but after a trip to Canada where I turned off Network Data to avoid the roaming charges - I suddenly was getting ~40 hrs on my battery.

I've tried turning of auto sync'ing and background sync - changed almost everything to manually sync.

I've downloaded TraficStats Lite to see what is using the data. With all the auto sync turned off, I'm getting very little traffic, but there are system requests, amazon appstore, and some others.

It seems that even if I'm not downloading anything (or very little) - just keeping the connection on is draining the battery.

I also get ~40 hr range when I'm in airplane mode with WiFi on - with K9 Mail, Trillian, and all auto sync on.

So, I'm pretty sure its the Network Data connection (whether active or not) that is the biggest drain.

I've tried voltage control with the UV Kernel listed in this thread (OTB v1.3), but every voltage I tried - including just leaving the stock defaults - would give me the SOD. immuts Kernel has been working fine. If there is another UV Kernel to try, I'm willing

Thanks for any idea.

I just flashed 1.5 OTB it looks like steps 100 and 900 Mhz were taken off, im going to give CFQ scheduler a try and see if I notice any improvements.

If you CWM to recovery, under Advanced is an option to enable 100 Mhz, I think 900 is just gone.

Running OTB 1.6, using BFQ scheduler, my settings are as follows:

1200 -25mv
1000 -50mv
800 -50mv
600 -50 mv
400 -75mv
200 -75mv

Running stable and strong. Going to try upping the UV and OC incrementally and will come back and change these when I find a stable ceiling.

Nice sharky same setup as mine although i havent dropped 100mhz step yet.

Running OTB 1.6, CFQ Scheduler:

200 -100mv
400 -100mv
600 -50mv
800 -50mv
1000 -50mv
1200 -25mv

This was running fine and I just boosted 600-1000 up to -75 and I will see how that runs.

-50 across the board
1200
1000
800
400
200

I took the 600 step out as it never got used at all according to cpuspy

I have had the same trouble with freezes and force closes. cfq scheduler has been the best for me so far

Trying this one now too. So far so good. Even with the new 1.6 Kernel mine still doesn't like anything above 75.

Was sticking with Comavolt until I saw that you were sporting the OTB 1.6 and I decided to give it a try. Previous OTB's would give me sod's with anything over -25 on any of the states.

I flashed OTB 1.6 and went with your settings exactly and my phone seems so much snappier and there have been no sod's or any other issues so far. I had never done any benchmark tests before until after having the setup I have now, so any data is really meaningless for the purpose of comparison, but Quadrant showed a result of 1705, which seems pretty good based on what I've read. Too early to tell about battery life, as it's only been a day or so, but I'm happy with the results. Thanks!

Have you messed around with more OC and UV yet, or have you just stayed with these numbers?

Searched for it, but couldn't find any post with answers.

I just restored my phone. Went back to stock and then back up to UKB2.0, OTB1.6, with the ED04 radio.

Since restoring everything, none of my VC settings will save. I'll plug 'em in, "Save as boot settings", but after boot everything has reverted back to original settings. What needs to be done?

I am using CPU Spy as suggested by JT in his OTB 1.6 instructions on XDA. My question is, how do you use the information gained by its results to adjust voltage control settings. Thanks guys

CPU Spy will show you which steps are being used the most by the CPU. You ideally want to maximize the UV on the most used steps to get the best battery life. Those steps that are not used much you don't have to UV as much. Thats basically it in a nutshell. You might find that some steps are not being used at all.

Well.... the 1200 voltage step is being used 74%, obviously way more than the others. How should I adjust my voltage control accordingly?

you also need to reset the CPU spy when u unplug the phone...by anychance with getting 74% at 1200 thats not right, were u charging the phone in MIUI lockscreen?

Actually yes I was...

Ok that is a bug in the miui lockscreen while charging that is stays in 1200mhz and never goes to deepsleep. So theres ur prob there. Dont charge in MIUI.....

Yeah, that step should not be that high. The highest should be the ones on the low end like 100mhz if you are using that step.

Gotcha... thanks. So, how do I use the info? Lower the voltage in the steps that are used most?

You need to "apply now" first... then save as boot settings
