Stock voltages and frequencies - on demand

Charging - stock frequencies - on demand

screen off - 200-500 conservative
[AT&T Samsung Galaxy S II SGH-I777] moustro:
I use h8s2 rom. Great battery life with jd on aggressive. Same results as with UnNamed. With cm7 and MIUI i had really bad battery life with the same settings. I tried conservative setting but I experienced a lot of lag. I am still new to android but this works for me without sparing performance.
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Default frequencies, ondemand

Hey guys I have a few questions

Can you set the setting too low to too high?

Have you guys seen a decrease in performance?

What is the middle ground between performance and battery life?

Thanks

You will lockup if you set the governor below 500 when the screen is off, in some situations. 1600 is the max you can set it for, it may or may not work for you. Some have said they need to overvolt to get to that speed, which is dangerous. 1400 is good enough for anyone. Using the ondemand governor is the safest route. It adapts to the your current needs very quickly but should still save battery.
[AT&T Samsung Galaxy S II SGH-I777] penguinlogik:
At 1600, the battery starts discharging while on the charger and your phone gets heated up to a dangerous level, and its not stable unless you raise your voltage by alot. And yes, your screen will lock up under 500 if you are on stock.

Set CPU needed?

New SGS2 users here and trying to read and search out as much as possible before posting, but this raises a question.

I too am running UnNamed (1.2) and I was wondering if one NEEDS the SetCPU app at all. Meaning that if I change settings in SetCPU are they overriding any settings in Entropy's driver?

I have my SetCPU set to 500-1400 conservative and things are running smooth. With Juice Defender Ultimate I can easily get 2 days battery with MY use which is somewhat light I would say.

Just wanting to make sure I am not inadvertently stepping on anything on Entropy's driver.
[AT&T Samsung Galaxy S II SGH-I777] penguinlogik:
Entropy sets the CPU governor to conservative which causes a tiny bit of input lag, and a bit of lag because the cpu doesn't want to clock up to max speeds as quickly. If you do set the governor to ondemand (say for charging) it would override the settings. Setcpu is useful to save batterylife say for instance, under 30% battery life, where you would keep max clock speeds to 500-800mhz instead of 1000mhz-1200. Or when charging, you want to play some games, you put the governor to on demand to give you better performance. I was able to undervolt my cpu stably to 1450,1325,1200,1100,1000,900,825 (1600,1400,1200,1000.,800,500,200 respectively) If you are using your phone somewhat lightly, JD actually uses alot more battery usage because of its excessive wakelocks. I figured that out after a couple days of testing with JD/without, and the only thing its useful for is the night schedule where you can disable data in the night.

TL;DR Use SetCPU if you want to undervolt/adjust Governor for different profiles, if not, have fun with your phone plugged in most of the time.
[AT&T Samsung Galaxy S II SGH-I777] cesande:

[AT&T Samsung Galaxy S II SGH-I777] dreadlord369:
Ah I was bored at work and decided I would try undervolting a little bit. I set it to performance so it would be forced at 1200mhz. The voltage is now at 950mv and the stress test has been running fine for 15 minutes. Gonna let it hit 30 for now, at home I'll try for a full hour. If its stable, then my settings will be for anything at 1200mhz and lower, 950mv. I'll lower the the voltage for the lower clocks later on. I'll try overclocking tomorrow and get back to you guys. Just wondering, how long do you guys normally run the stress test for?

[AT&T Samsung Galaxy S II SGH-I777] penguinlogik:
At those forced speeds, charging will take forever. Performance automatically forces top clock speed so 1400-1600 is useless. Having Battery <15% on the bottom is also useless as the <51% would overwrite it.
[AT&T Samsung Galaxy S II SGH-I777] dirtbikerr450:

[AT&T Samsung Galaxy S II SGH-I777] CollegeProfesor:
How much should I undervolt?

So far ive reduced each one by 75, im not seeing much improvement in battery life

Thanks
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
that's pretty impressive to be able to knock them all down by 75 and still be stable. you must have a good cpu in urs.
[AT&T Samsung Galaxy S II SGH-I777] penguinlogik:
You can't just reduce each voltage and think its ok, you have to test each speed and make sure its stable at that voltage. Also battery life depends on how you use it. If you ran a synthetic benchmark that drains your battery over a day, you will see improvements, however since daily use is always different, just undervolting won't show much of an improvement.
[AT&T Samsung Galaxy S II SGH-I777] CollegeProfesor:

Well I've asked for help but didn't really get any clear answers, should I go back to default and make the voltage something different?
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:

That's what I'm getting with UnNamed 1.3:

Set CPU 800-200 conservative for main profile.

Screen off 500max-200min conservative (100 priority).

Charging 1200max-200min on demand.

I didn't do any undervolting, I also used betterbatterystats to check for any weird wakelocks as well.
[AT&T Samsung Galaxy S II SGH-I777] keesimps:
I am really happy that I found this thread, as I was very disappointed with my battery life even though I had gotten it in the range of 13-15 hours with Juice Defender advanced settings... I made the changes in setcpu (didn't have any profiles set until then) as per the OP and slightly tweaked them to a minimum of 200. This combined with JD I got 25 hours over the weekend with 13% left and yesterday with a work day got almost 15 hrs with 33% left, so in theory should have been able to get 22 hours or so!

This is exactly what I wanted; I wanted to have a full day of work and be able to go out or run errands without my phone dying or me having to charge in the car and at work, which was not the case before. Now it seems like I can do this with battery to spare and the padding will cover any heavy usage that I may incur. Thanks again to the OPer.

By the way - I am running UnNamed 1.3.0 and I'd say am a moderate user. The only thing that I do notice about the low of 200 in setcpu is that when I turn the screen off and then on sometimes, I see whatever I was in or working on first and then a second after the lockscreen pops up. This doesn't bother me much as it is not that bad of a lag and the extended battery time is more worth it to me.

So, has anyone done 200-500 with the screen is off and not experienced any of the lag issues that I noted? I may need to try this and see how much it affects my battery life if so...
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Seems that a lot of people, including myself, have screen off set to this. The only lag I experience is coming out of sleep with the device set to 200 min and max (and it's only for a second or so on initial wake). It's mainly a protective measure to prevent your CPU from ramping up too highly in the event of a wakelock. So in those situations, it would improve battery life.
[AT&T Samsung Galaxy S II SGH-I777] SpectraDawn:
Ever since I installed this app my battery has been plummeting!

Main is set to 1000 - 200 conserv

Screen off 500 - 200 conserv

Was at work today for about 7 hours and the battery went from 100-80% with the screen off about 99% of the time, since I can't even use my phone... And if I turn on my phone, the screen is at its lowest brightness, no auto brightness.

Haven't messed with the volts at all.

Could BLN have a huge affect on the battery?
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
If you have the duration set too long, yes. Remember, anytime it's active (showing a notification), there is a wakelock. Mine is set to timeout at 5 minutes. I'm curious as to what others have theirs set to.

[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
Setcpu will not cause battery drain like that. Entropy512 talked at length about Bln causing battery drain. The lights themselves use next to no power. It's the process that keeps them lit when you have an unread message that stops it from going into deep sleep. He was hesitant to even release this enabled on his kernel for fear people wouldn't read and then complain their battery is getting eaten up.

Development is still being done on it. It was released as is partly due to people wanting it despite the issues.

[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Your battery profiles are ordered incorrectly. You have to give higher priority to lower battery levels. Consider: when two profiles are met (e.g., battery level is below 30 and below 10), it will set the profile to the one with the higher priority. Order your battery profiles oppositely and you'll be good to go.

I'm on Unnamed 2.2.1 with SetCPU doing 200-1000 conservative and all voltages are at -100.

Yesterday I reached 16hour's at ~50% so i feel this is a pretty stable %/hour and not just a one day thing.

What should I know before I go messing with Voltage? Don't want to freak my phone out or anything. I see above someone said they have it at -100 across the board. Is a -100 across the board a good idea? I find it rare that mass changes across the board for something like that would not flake something out.
[AT&T Samsung Galaxy S II SGH-I777] jazzboyrules:
If using SetCPU,

Set the voltages to any level (safe enough to not burn the CPU. But as you would be undervolting for battery optimization, it will be safe) you like. Make sure that you have the 'Set on boot' option unticked. In the case you undervolt too much, your phone simply will lock up and you will need to reset it by holding the sleep button for a couple of seconds. As you did not set the 'Set on boot' option, your phone will boot up with the last stable voltage configuration. So yeah, just keep on undervolting till you reach the point where your phone is stable enough to not lock up randomly.

If using Voltage Control,

Voltage Control doesn't seem to have the 'Set at Boot' option but it has something similar. I would choose not to use the init.d tweak to set the voltages. Use the app-recommended setting. That would set the voltage after your OS boots up and gives you about 15 seconds to apply the voltage settings (you will see that in the notification bar). So in the case you undervolted too much, your phone will lock up, you will have to reboot, and then simply cancel the application of your last VC setting before that 15 second counter times out, change the voltage settings, repeat.
[AT&T Samsung Galaxy S II SGH-I777] nasapunk88:
I would also recommend that you hit Menu->Safe mode instructions and then Extract zip. This will place a zip file in your storage that you can flash to revert to normal settings in case you check the "set on boot" and it keeps locking you up.
