SetCPU Gingerbread

Is anyone using SetCPU with gingerbread?
I'm using GingerVillain 1.5 but I can't seem to find the right profiles with SetCPU.
Oc'd @ 1,2 Ghz without profiles.
Because when I use the screen off profile, my screen sometimes won't turn on.
Screen off - min 245 max 1200
Can someone help me finding the right profiles?
Share your user experience.

In my experience and many others too, the profiles are not needed. The only profile you should ever need is a temperature profile and that's only if you really have it cranked up.
Having a screen off profile is always bad since switching to another profile doesn't happen instantly - there are polling intervals involved and until the next cycle runs your phone will still be using the screen off profile. That makes the phone slow which causes SetCPU to take longer in switching profiles, bogs down the cpu and it becomes a vicious cycle for a few seconds (sometimes a couple minutes). All the while it's draing your battery because the cpu has to work harder. Even regular profiles eat the battery due to the constant querying of the systems status and processing power used for that - which is the main reason you'll hear people whining about their battery life (some aren't effected as much).
Profiles are just not a good idea except for a temp profile for those that oc to the higher GHz (probably 1.4+).

You could try using cpu tuner instead. Gives you way more options.
CM 7

You have a lot of options with cpu tuner.
What triggers and/or profiles do you use?

My screen on/off has been working fine with CM7 nightlies before and after the RC1. I've been using SetCPU with a normal profile of 1017max/245min and a screen off profile of 365max/245min.
I think your issue is with overclocking. Idk about Gingervillain but as far as CM7 goes lots of people are having issues with the on/off animations and wakelock issues when overclocked over 1ghz. Try using your profiles and clocking at or under 1ghz and see how things change.
Not sure why anyone would really need a higher clock than 1ghz but what do I know. I dont see any slowdowns at 1017mhz and I feel that anything faster than that would lead to heat or battery issues?

Yes, screen off profiles work. But they drain your battery faster than if you have no profiles.

thanks bro, i OC'd to 1017 and there are no issues

I'm not so sure about this. Have you tested this at all? Starting using screen off profiles of 365max/245min have really increased my battery life, especially when my phone sits idle for a decent amount of time. I don't think you could see more battery life by leaving the clock at 1ghz while the screen is off.

Every kernel that I know of out there drops down the clock cycle when the screen times out. The reason not having the screen off profile saves the battery is because SetCPU isn't constantly sending requests about the phones state and then checking that against your profiles to see if it meets the parameters set in them.
Now it could be a bit different for you. You might have a different set up or different apps that make having a screen off profile useful (ones that constantly update or run in some way). You just have to watch your phone for a few days and get an app that keeps track of that stuff so you know which route to take.

This is very true. It is definitely hard to make a blanket statement because no two people have the exact same setup. All I was saying is what I've been doin with the screen off animation and I've been having pretty solid battery numbers.

High power consumption on auto-brightness

Hi!
I recently installed PowerTutor on CM7 nightly from yesterday. An app to display the power consumption in mA. Now I recognized some strange behaviour.
First I measured the power consumption with display on highest power. ->700mA
Second I measred with lowest power. -> 350mA
then I switched on auto-brightness. -> 350mA
When I switch on auto-brightness after having the display on highest power it uses 700mA.
Can anybody confirm this?
Thanks for your answers!

I'we noticed it too
After a clean install i always set the brightness level to lowest value and then activate auto brightness and it is ok.
I did this even on a samsung Galaxy s - Custom ROM 2.3.3 and it keeps batery from quickly draining.

I'll try it out on an original Defy and post results here. If it's a CM7 bug, I'm gonna post it on github.
Anybody else having noticed this?

Hi, i noticed this also after installing the cm7.1.
I found this issue from the battery usage info. On previous versions the highest consumption was from the cell stdby and idle phone, and in this version about 80% os the display

Exactly the same values, any solutions... Display eat so much more power compare to stock 2.2, but why... I want to try some tips about to decrease display consumption

I have reproduced the problem...but I think it is due to the way power tutor misestimates LCD power draw, not an actual of LCD power usage. See post http://forum.xda-developers.com/showpost.php?p=17674701&postcount=11806
and the few posts above...

This
The Defy doesnt have any reporting measurement in the Battery driver, this means we cant see how many mA are actually being consumed.
Doesnt matter if it is Froyo, Cm7 or MIUI, the Driver just doesnt provide the info to the OS. All we can use are Voltage readings and estimations.

[Q] Unbelievably slow answer screen appearing

Hello folks,
first post, pleasure to be part of the group
Arc LT15i, 2.3.4, doomkernel#11, 4.0.2.A.0.42
more than 10 seconds to wait to be able to answer a call
takes 3-4 sec to light the screen (it's an eternity when you have to answer), and often first appears the unlock screen, then after seconds the sliding green botton.
really sorry for the noobhood, but any ideas?
thanks a lot
Cavin

I updated my phone to latest official firmware and i alos have this lag, but not that much. It takes 2 seconds for the screen to show who is calling and to be able to answer it, and it takes around 0,5 seconds when pressing the unlock button to light up the screen.

same problem when i was using stock rom
but when i moved onto MIUI,the phone is pretty fast and answer screen appears pretty quickly

Which CPU scheduler are you using? I have seen that using smartass or other schedulers which reduce the clockspeed on standby can reduce the responsetime of the answer screen.

setxperia raise the clockspeed on incomming call to make the response a bit better.... ;-)

Thanks guys for answering
You're right! It's due to the clock's settings. May be, i'll come back to the former firmware any hints?
upgrading clock's frequencies works well, but drains battery faster (and this setup requires already a lot of energy ).
using "no lock" app, gains few secs
last night came up with the same good idea of using the incall profile
i noticed that using a too low min clock freq, the device is less reactive, although using "interactive", "smartassv2" or "ondemand". "scary" profile seems to work slightly better on incall reactivity. any experience?
Thanks
Cavin

If you use smartass (v1/v2), there's no need to set any profiles for screen off. The governor will stick to the lowest available frequency.
Smartass v1 used to have wake issues (on HTC Desire, at least), but v2 seems to be fine, I'm using it on the Arc S, I haven't experienced any lags with either stock or CM7 ROMs.
I'm not familiar with Setxperia and its settings, though, could something be set wrong, causing poor performance? Just a guess...

thanks
i noticed some lags with a very low min clock (e.g. 122), disappearing setting min at 8-900mhz (max 1.2ghz)
actually dunno why, but if i succeede in changing the rom discovering what to wipe, gonna tell you more

[Q] Underclock below 300MHz for Defy / Defy+?

I recently have bought a Defy plus.
Stock 2.3.4 ROM used so far with LauncherPro.
Doing OK with battery life so far, but now starting to look at the CPU over/underclock capabilities. Started with Antutu CPU Master and CPUTuner also.
One thing I haven't seen as yet is the ability to underclock clock below the min 300MHz.. or even whether this makes sense. I guess undervolting is the other option, but perhaps someone can guide me here.

use setvsel to oc/uv, thats the easiest and best app imo. although underclocking your phone below 300mhz may cause instability and makes the phone wake up much slower in my experience.
sent from my cm7 defy...

I agree with zakoo2: Going below 300 will not be a good idea and it will most likely not improve your battery life in any significant way:
My Defy is running between 300-600Mhz and right now the LCD screen is the biggest consumer: Changing the (auto-)brightness settings in CM7 will do *much* more to your battery life than going below 300mhz.

What really helps saving battery life: use setvsel and leave the minimum clockspeed at 300MHz, but set a vsel value of about 20 for it, then scroll down and enable "limit to vsel1 while screen is off".

Also, going below 300MHz will probably make the phone sluggish when waking up from sleep like if a call comes.
Sent from my MB525 using XDA App

im just change from 300mhz to 330mhz lowest. 300mhz will make my defy+ lag when got incoming call. im using smartass govenor.

I heard some guy out there got 80 MHz and running, but I'm not sure of it.
As people said, clocks lower then 300 MHz would make your phone run horribly while waking up (i.e., it would take a long time for the screen to turn on when receiving a call, and you would probably miss it most of the times). Setting 300 as VSel1 and limitting to it while screen is off (2nd-init enabled bootmenu has this option, and downloading SetVSel - free at Android Market - will also do the trick if you have a rooted, but stock ROM) will help you save a lot of juice. Using a lightweight launcher (I personally recommend MetroUI or Zeam) also boosts up batt saving. Last, but not least, setting brightness to auto or minimum (using frosted/mat screen protectors will help a lot while using the phone under direct sunlight) also saves loads of charge.
Obviously, using a light ROM (I think Barebones may be a good option, though I think it's not suitable for me, but it's a personal matter) and calibrating your battery in a monthly basis (via manual calibration - you can find how to do so by googling -, wiping batt stats in custom recovery and/or using the batt calibration app included in most ROMs - but also free at AM) also help.

Is my Note 4 defective?

I need somebody's help. The coolest my Note 4 CPU/GPU seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius

Okay, so I got rid of my Note 4 so this is off of memory (full-disclosure). My Note 4 always ran pretty hot when it had to do anything. When flashing ROMs I'd be lucky if the CPU was below 70 C and any time I'd be playing a GPU intensive game it would get too hot to touch. I never had a lot of issues with the battery temp being too high though despite this.
As far as solutions go:
1) Screen res might help.....but I would try my other suggestions first
2) I wouldn't recommend disabling cores, it just makes the other two have to work harder to accomplish the same tasks and may be worse overall.
3) Kernel adiutor will allow you to do two things: adjust thermal throttling and adjust max GPU/CPU frequencies. I always reduced the max GPU frequency on this phone to lower the temps and adjusted thermal throttling to 55 C. The only CPU adjustments I did were to make sure the CPU wasn't overclocked.
4) I know you said it wasn't a rouge app, but get a task viewer (this is a good one) just to make sure (I had Nova taking 25% CPU usage in the background because I restored it from TiBu).
I saw your post in the NSeven thread and decided to respond, but please in the future try not to post errors in other threads unless you have the issue in that ROM. It sounds like you might have the same issue in that ROM as well, but you didn't say so in your post.

Well first of all I would like to say thank you! I have been hoping for a while that someone would have some knowledge on the subject and I very much appreciate yours. Secondly, I apologize and I will try to refrain from posting the wrong thing in the wrong area in the future. Thirdly I have kernel auditor when I changed their frequencies on my CPU cores they just change right back. If I set a minimum it will stay but then if I try to set a maximum it resets them both to the default setting. I will turn my other course back on though thank you for that information do you have any idea why I may be having this frequency issue?

You're welcome, and no worries for the post . As for your third point it would be really helpful if you tell me what you're running.
Could you list: kernel, ROM, root method, Android version, and any kernel mods (govtuner, skynet, etc)?
Also, does the same thing happen when you set a GPU max frequency? Have you tried having the settings run on boot and then reboot the phone?

Yes I have tried that a couple of times I am currently running the nseven ROM with the CPU frequencies set at a minimum of 300 megahertz and a maximum of 1190 megahertz, or at least that's what I'm attempting to do LOL I have not tried changing the GPU Max frequency. The N7 ROM I believe is Android version 6.0.1. here is what I have tried
Wiping cache in recovery
Starting in safe mode
Factory resetting
Turning off certain settings such as WiFi calling, data Etc.
Using apps such as greenify to limit background processes.
Changing screen resolution to 720P
I actually installed this ROM hoping that it would make a difference because I have the same exact issue on the stock ROM before I ever unlock my bootloader or rooted my phone at all. And according to the sticker on the back of the phone it is not nor has it ever been water damaged. The picture I have attached shows my phone's activity just while writing this reply to you. In the bottom left-hand corner you can see the statistics. Sorry for the Inception lol
