HTC EVO 4G :: Rooted SetCPU Tweaked With Dmg Rom 3.2 Battery Issues

Jul 13, 2010

I want to state that I LOVE my phone and it perfectly does everything I need it for. I just have a minor problem. With all the tweaks I've done (and redone) I can't for the life of me get my phone to last more then 8 (or less) hours.

Here is my phone settings.

I'm rooted via the new root method (ota simple) from xda. It worked flawlessly and then I installed the dmg rom on the Battery Saver method. Got a little bit of time. THEN I purchased and followed the SetCPU program tweaks and did that to the T. I also have the following: GPS On. Mobile Internet on (no wifi or bluetooth).

I have all "Friends" syncing off but I have my gmail and work email on push (required via my job)

I have my brightness set to almost the lowest and I have to charge my phone about 2pm everyday otherwise my phone is dead.

Typical day: Wake up at 7am unplug phone. Check email/comics then go to work. I'm an IT sys admin and am required to have my phone/answer emails throughout the day. but at least 4 hours the phone is just sitting there or I'm lightly texting on it. But no matter how little or how often I use it it gets about 30% dead about 2pm with ALL the tweaks i've done.

This might make all the difference. I have LOW signal at work and home (1 little bitty bar to none). And my cell standby is almost always above 50%. But with all the tweaks (yes I've done the network app and yes its on CDMA) with PRL and profile updates (rooted and unrooted) it still has the problem.

HTC EVO 4G :: Rooted EVO - SetCPU

Sep 20, 2010

I recently rooted my EVO (Tonight!) I downloaded SetCPU so the processor will run faster when its awake and slower when its not. I can't for the life of me seem to figure out how the heck to get it to overclock. I don't see the word anywhere in the app, and the slide bar only goes up to 998 mhz (my Evo's max?) Is it in the other menu settings I don't quite get?

Samsung Vibrant :: Rooted - SETCPU

Jul 25, 2010

Rooted my Vibrant pretty much as soon as I got it, installed SETCPU and while it did make my phone MUCH more responsive it was also causing problems.

I asked for help on XDA but most gave pretty vague answers, so I eventually ended up uninstalling it....

Well, anyhow, I found this really helpful post and now I am going to give SETCPU another shot. So if anyone else out there is having issues read this:

Android :: Rooted Evo - Installed SetCpu

Jun 14, 2010

I just rooted my new Evo and installed SetCPU, i set up some profiles for when my battery reachs like <25 and i was testing this out at like <75 and noticed that even though the notification shows up as the profile is active, in systempanel app and also even in SetCPU is still shows the cpu reaching core speed of 998 instead of the speed it should be capped at...

So my question is, is setcpu actually working?

HTC Desire :: SetCPU - Save Battery

Sep 11, 2010

Ok just installed this on my Desire and wondering if my settings seem ok.

Initial set up set to ondemand and ticked Set on Boot.

On Profiles I have set as follows;

Sleep/Standby - 576 Max, 245 Min
Power < 80% - 806 Max, 245 Min

Both of these are ondemand also.

Should this be enough to notice some significant battery savings?

Do you reckon I will run into any problems in terms of performance as time goes on? (seems ok just now)

How to save battery but not lose out on performance?

HTC Desire :: SetCPU - Increase Battery Life

Sep 6, 2010

SetCPU claims to be able to increase your battery life by limiting the speed your processor can run at. This seems like sound reasoning at first, but then I remember roughly what a CPU is and how it works...

So let's say you've set a profile so that when the screen is off it will be limited to half the clock speed; around 500mHz. Lets then say your email wants to get updated, so your processor chugs away that that. If it was set to full capacity it may take say, 1 second to complete the task then go back to it's idol state. With SetCPU limiting it, it would take twice as long and would still use exactly the same number of cycles as before.

In fact, when you think about it, it doesn't actually matter what speed your phones processor is running at all the time, what matters is how much work you're asking it to do. Surely the best and only way to increase battery life is to simply have your processor complete less tasks, therefore using less clock cycles? Sending a text message uses the same amount of clock cycles no matter what your max setting is, so as a result uses the same amount of power.

If anything, having SetCPU running all the time just gives your phone more work to do and therefore decreases battery life?

HTC Incredible :: Increase Battery Life - Is SETCPU Working?

Oct 7, 2010

I rooted my phone about 2 days ago and I did a nandroid backup, titanium backup, used titanium backup to freeze some of the bloatware.. Have not yet installed any ROMs or Kernels. I got SetCPU and made several profiles in an attempt to increase my battery life. I wanted to see if it was working so I set up a widget, and despite the fact that my battery was at 20% (I have a <25% battery profile setting) the max was still 998

HTC Eris : Running Several Settings On SetCPU But Still Low Battery Life

Aug 16, 2010

I have tried several different Froyo Roms over the past very weeks. I still can't get any good battery life out of them compaired to running EE3.0. Yet everyone tells me they get better battery life while running Froyo. My phone has currently been unplugged for 9hrs 13 mins. It has a total of 50 mins talk time and I have sent 30+ text messages. My battery level is @ %73 running EE3.0

I can't get a total of 11hrs out of my phone when running any of the Froyo Roms. Ive tried running several different settings on SetCPU but nothing noticable. Only thing I notice is that when running Froyo the largest use of my battery is my Display. Yet when running EE3.0 the largest use is Cell Standby and Display is the lowest. But I have tried turning the brightness almost all the way down on the Froyo ROM but it doesn't make any difference.

HTC EVO 4G :: ROOT - Using SetCPU - Perflock Disabler To Save Battery - Underclock

Jul 8, 2010

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.

Samsung Captivate :: Battery Report After SetCPU Application Downloaded

Aug 19, 2010

I figured I would throw my 2 cents in on my battery performance. I was mildly disappointed after the first week of use with my phone. It was without a doubt worse than my old iPhone 3g. I expected this due to larger screen, running widgets, ect. so I am not complaining. However, a couple days ago I downloaded the Set CPU app from the marketplace and set it to minimum every time the screen turns off. The difference is amazing, I have not charged since 7:30am yesterday and just now at 340 I plugged it in, it was around 5% left.

I really wanted to push it and see how much more I could get but I don't want it to die on me tonight, im going to a baseball game so I don't want to be stuck without it.As far as usage, I spent about 45 talking over bluetooth, I have sent about 15 texts and received about the same. I checked Twitter a few times, for a few mins each time. Spent about an hour browsing web, and downloaded a couple apps from the market. Before this I was charging my phone after an 8 hour day at work and had almost no juice left. YMMV but for me this has been well worth the 2 bucks.

HTC Eris :: Short Battery Life On Newly Rooted Phone

Nov 22, 2010

This is the first time I've rooted a phone, and i picked the Kaos Froyo V38 as the rom, but I've noticed since i did all of this my battery has been far far worse than what it was un-rooted. Today, for example i had my phone off the charger and on vibrate (with gps, mobile network off) and i was down to under 15% in under 5 hours. This is so much worse. Is it because i'm now running 2.2? What can i do to help this besides wiping the battery data (in the recovery menu)? I'm not really good with all of this yet, so some suggestions would be wonderful.
