So I'm using jRummy's over/underclock app in conjunction with setcpu. Anyone know what the best settings are to increase battery life? Phone is fast enough so I'm not too worried about going under 1ghz.

I'm sure many people has seen the thread where OverclockWidget was claimed to have increased the battery life for some people. Near the end of the thread I became skeptical and proved that it had in fact no effect on the CPU speeds at all, and so can not save battery life. Well, good news is that a new function in the competing SetCPU app will now get you a real, tested increase in battery life.
According to my tests, my Evo with the screen off should theoretically get a 64 hour battery life!
Know what you're doing? Short version: Get latest SetCPU (version at least 2.0.0) and use Menu -> Perflock Disabler in the Main tab to enable underclocking.
Don't know what I'm talking about? Good, follow this tutorial:
Prereqs:You need to have ROOT. Unrevoked root method is confirmed to work, and so is Toast's root method.
Usually I wouldn't recommend using Unrevoked, but it's just so fast to set up, and perfect for those who have no clue what ROOT means.
Buy SetCPU from the market, or download it from XDA forums for free. Please support the developer of this incredible app! The version must be at least 2.0.0b
Be on the STOCK kernel. If you're on a custom kernel, chances are that perflock has already been disabled, and you won't need this tutorial to underclock. Some custom ROMs come with the stock kernel (like Fresh 0.5.3) and some don't (like Baked Snack .9.6)
Alright, got the prereqs down? Lets start this.
HOWTO:Open SetCPU and give it root permissions as necessary. As a control, go into the Info tab and do the Long Bench a few times. You should get around 1000ms.
Go to the Main tab, hit MENU, hit Perflock Disabler (read the warning!), and hit Disable Perflock Beta: May crash!
It will work for a while, and then say it's successful. You can then click the X on the top right to exit the Perflock Disabler.
Go into the Main tab and drag Max: all the way down to 245000 (245Mhz). Make sure the green xxx max xxx min label above the sliders show 245 for both and also disable any Profiles you've set. Go to Info tab, then hit Long Bench again. This time you'll get something ridiculous like 5000ms, meaning that the Perflock Disabler has worked!
Change your settings Profile tab to something similar to my settings. You can mess around with the Battery < xx% profiles to fit your needs. Your exact Profile priorities do not matter, it's only important that some have HIGHER priority than others. On the Main tab, set Max all the way to the right (998400) and Min all the way to the left (245000), Scaling to ondemand, and check Set on Boot. Do not check Set on Boot yet if you're the super careful kind. You can check it later when you've tested that your phone isn't crashing
The last entry is Battery < 100%, set at lowest priority, with MAX as the highest value, MIN as the lowest value, and scaling as ondemand.
Congratulations you're now able to underclock your Evo!
Comparison:
The only applicable parts is after the charging finishes (after the solid green bar ends)
Before Perflock Disabler:
After Perflock Disabler:
See that little dip at the end? That's when I was turning the screen on and messing with the phone for this tutorial. What a difference.
Disadvantages:Yes, not everything is happy and pretty. As the Perflock Disabler warning says, you HAVE to apply the Perflock Disabler on every boot. If you forget, then your SetCPU settings will have no effect on the Evo. Install a custom kernel that already has Perflock disabled if you do not want to do this on every boot.
Also, since this clocks the Evo down when the screen is off, you may get a slight (super slight!) delay when you turn the screen back on. This is because the profile changes from Screen Off to Battery < xx% and SetCPU needs to clock the CPU from 245mhz to 998mhz.
FAQ:
What is Perflock Disabler?
HTC added a "perflock" in their stock kernels to prevent over/underclocking. SetCPU's Perflock Disabler, like its name implies, disables this restriction.
How come your screenshots show that you can go down as high as 1.19Ghz and as low as 128Mhz?
I'm using this custom kernel.
Will this work with OTA update xxx.xxx.xxx.xxx?
Yes, as long as you have root, and don't lose it when you update (do your research!) then this will work.
What are your settings?
Wifi ON, Bluetooth OFF, GPS ON, Mobile network Data OFF (ATT contract with dumbphone still not over), Screen Timeout 1MIN, Brightness AUTO, Advanced Task Manager set to SAFE kill tasks when screen is off.
What is that cool looking battery monitoring app?
That's SystemPanel, paid on the market. A free alternative is JuicePlotter, also on the market. Screenshots were taken with Drocap2.
Location & Security Settings --> Use wireless networks (location determined by WiFi and or mobile networks). Does this feature use up resources and/or battery?

POWER up to 360 min / 6 hrs
USAGE TIME (CONTINUOUS)2
BATTERY TYPE
1420 mAh lithium polymer
STANDBY TIME2
up to 325 hrs / 13.5 days
I did away with all the motoblur stuff but I've been having problems with my battery life still.... I've been running a bunch of apps, IMing, emails, wifi etc.... and it's been lasting about 6 hours.
Today I cut everything back using "advanced task manager free" and after about 6 or 7 hours I still only had like 40% left...... no where near anything like the specs.
Six hours continuous talk time? 325 hours standby? Certainly not the way it comes out of the box! Who are they trying to kid? Is anyone getting anything near this? Is there even any way to get close to that? WTF? Does anyone find these specifications deceptive?
My battery might not be the best but it seems to be at least average from what I hear. Please tell me what setting I need to get this kid of battery life!
Some people here have said deep cycling the battery helps but that's supposed to be bad for lipo batteries
Some people also say you need to charge the battery fully before first use or you can ruin it but no other sites mention that.
I want to be able to use gps and apps and wifi and email and IM during the day w/o being tied to a charger all day. I was a dedicated sidekick user but now love the cliq.... except for the battery life.
I thought of getting a spare battery but don't want to lug an extra battery around...... I've seen apps (APNdroid) that shut off the data to conserve battery life but I want to use the features of the phone... that's why I have it....... what's the answer?
Btw: "battery graph" and "spare parts" are great apps to monitor battery usage.
Also, in some places it says the bp6x battery is rated at 1300 mAh and in other is says 1420 mAh but it's the same battery! What's up with that?
Question: What kind of battery life do you experience with "normal" usage? Does anyone know what settings to use to approximate the times noted in the Cliq specifications?

Whenever I check it, the widget shows the phone is at 550, unless I manually move the slider to 1200. Does this mean my phone's not really running at 1.2, or am I misunderstanding how the overclock process works? Also, is there a way to do some sort of speed test? (I don't have set cpu and I can't buy apps at the moment) I do know when i move my slider to 1200 the web seems a lot faster, but whether thats real or placebo is beyond me.

[Fix] Stock recovery coming back/Custom recovery wont stick
So i tried the next step on my agenda, which was to find an overclock kernel for Froyo 2.2. Ive tried a handful of ChevyNo1 kernels, and a couple from jdlfg and none of them seem to take. The speed scale in SetCPU remains at a max of 600mHz, while Overclock widget shows me a possible max of 900mHz. Even if i try to set the max at 900mHz in Overclock widget, the widget never actually reads that high and SetCPU never reflects that speed either.
I can confirm that I have root, and both SetCPU and Overclock Widget are being given superuser permissions.
I see ChevyNo1 has some Froyo Kernels for overclocking. Which ones should I download, I am not sure of the differences between low voltage and ultra low voltage.
Also are these the best Kernels for overclocking, or are there better ones?
Warning, this process may cause our phone to become unstable if you clock it at the wrong speed. I advise that you do not continue onto steps 2 and 3 until you find the settings that work for YOUR phone best.

View 23 Replies View RelatedAny D1 using this app? Seems like you can set the speed anywhere from 250Mhz to 1Ghz and you can also tell it have different range when screen is off. Is this accurate and how does this compare to SetCPU? OverclockWidget (Need Root)
View 2 Replies View RelatedI was wondering how they actually reach their max speed? If you have a kernal that has 250, 600, 800, 1000, 1200. Does it start at 250 then go 600, 800, 1000, then finally hit 1200? Or does it jump to the necessary speed that your using (like start at 250 then it could go to 1000 then 1200)? Because if it has to go through each speed to get to its max, then a kernal with 5 different ones would be much better than 10 wouldn't it? I've never seen this question asked before, so does anyone know how they actually get up to their max?
Just so everyone knows I'm rooted and running overclock of 1200.. I have it set up. Just want to know how it works.
