i like the screen off profile, as that makes a real difference for me in battery life, however i see no point in having battery profiles. do you really want your phone to become slower just because you drop under 50% batt?
normally i would want it to keep going full speed and in the case that im on the road and need to save battery as much as possible i would change the setcpu profile myself (and probably switch off sync and 3g)
Your <30% profile will never kick in, since that is also <50% which has a higher priority.
Newb question: Does one have to have a rooted phone to install Set CPU?
^^^ Yes.
SetCPU needs superuser privileges to do its thing.
Priorities fixed now, I used it with less than 50% and the phone was just as fast doing regular tasks and web browsing
Am just using screen off dont need to use any other settings.

You also need a custom kernel, the htc one can only underclock not overclock

I just use <30% battery, 768Mhz. I let HAVS do all the rest.
So because I have a custom Rom Leedroid, I dont need to disable the driver?

What is HAVS?
Also, what's better for batt conservation (w/out sacrificing speed): Undervolting or underclocking?

HAVS is a set of instructions from the kernel governing the CPU, it undervolts and under clocks the CPU when it is not in use. Undervolting and underclocking go hand in hand.
I have just 1 profile:
screen off: max around 384 MHz. and mim 245 MHz.
Does that makes sense? :-O

I've never cared about battery life before because I'm typically near a charger however I'm going to the beach for a few days and will need my phone to last.
What's the best kernel/set up for me if I'm running Fresh 3.1.0.2? I don't care about performance, fps, mflops, etc for these few days as long as the battery lasts and the phone is stable. I have setcpu on my phone but don't really know how to use it.

The latest cfs kernels are supposed to focus more on battery life than performance. Do you underclock cuz that's a big help too.

At 998 max now, where should I be? Which cfs one?

I'm running Fresh and Netarchy's 4.1.8 kernel.Creating a set CPU profile for when the phones screen is off will increase your battery life quite a bit.My screen off profile has the CPU max at 245 ghz and the min at 128.You can also scale back your max from 998 mhz to around 500 mhz and save battery without your phone being so slow that its really noticeable during normal use.

Interesting. What kind of battery life do you get? I thought I read a while back that going below 245 was a bad idea. Guess not?

It's more stable with the newest kernels. I'm set at 245 min and max when the screen is off and I usually see a 1% loss every couple hours but I haven't paid a lot of attention to it lately cuz like you, I'm usually near a charger. Battery life while using the phone still isn't great but I kind of expect that from a phone like this. There are some good battery conditioning tutorials in the forum that help quite a bit too.

Here's my usage for the last week.I go off charger at around 7am and usually have about 70% charge remaining when I get home at 5.

Hello all... I'm new to Setcpu and have been able figure out how to OC and UV while still keeping everything relatively stable. As of now I'm experimenting with making profiles, I was wondering if someone could post a screen shoot of their profiles and pass on any advice. I am running TNZ Blend 2.6.2 with the Hitman kernel. Here's a screen shot of what I have so far.

The only thing I would comment on is your "screen off" there is no reason for it to be scaling/jumping from 800-1200 "ondemand" while the phone is not being used or the screen is off in general, just have 800 low and high or have 800 as your high and set it to "performance" so that there is no polling being done and it will set itself to the high value which would still be 800 anyway.
You might have a reason for that setting, just trying to save you a little bit more of battery juice.
Definitely bring down that screen off! I have mine set to 200-500 ondemand. I'm sure it'll save you a lot of battery. Also the battery 100% is kinda pointless because that's what the main profile is for. And expect your phone to get extremely hot if you use it while charging since you have it overclocked. I did that same mistake now I keep it at 200-800 to avoid the over heating.

Just a recommendation...you should give tegrak a go. I find it to be much more beneficial than setcpu...
Why scale cpu depending on the battery level? I prefer scaling CPU on my phone by the temperature. 1.6Ghz normal usage and then gradually scale it down if it gets too hot. I bought this phone for its performance, not battery life, which actually is pretty amazing for such powerful device.

be careful with Tegrak, as it doesn't work with some of the non stock kernels, and will freeze your phone for sure..
Pretty good. You don't need the battery>100% profile. Adjust that from the main page.

Yikes! I wasn't aware of that. Guess I'll do a bit more research on that before I fire out recommendations. Note to self...not all devices have the same setup as yours
Can anyone please give me undervolting tips for battery life cause I can't get to 3 hrs on screen time with standard battery
I am with latest Franco kernel
I don't think the problem from the ROM cause its the same on every ROM I tried
Thnx for any help

These are the voltage settings I'm using for the CPU, ondemand governor with standard battery. Hope this helps.

Undervolting tip: Undervolting varies per phone and requires trial and error. If your phone hotboots, you went too low.

Agreed!
I started by letting SmartReflex calibrate the voltages and using those voltages as my starting point. Undervolt by 20-25 at first and see how stable it is...trial and error! Here is a screenshot of my SmartReflex calibrated voltages, but they are different for every phone and sometimes get calibrated differently for me when using various ROM/kernel combinations. I am currently running the Kang CM10 ROM with the Glados kernel, but have used Franco in the past with similar results.

Could I know the apps name of your screen cap?
Recently I've decided to overclock CPU and evaluate efficiency in term of speed by using one of the famous and best FRANCO KERNEL.
So I've captured 1 minute 1080p raw video with stock settings (no mods or hacks to mediaprofile.xml file) and rendered file in Google Movie Studio in 1920x1080 aka 1080p format and High quality.
Consequently, the results were as follows:

As you can see the most efficient OC frequency is 1305Mhz. All above are way slower, cause CPU gets hotter and efficiency decreases.
Yes, do admit overall smoothness is by far better in comparison to stock kernel, but as you can see overall efficiency is not a deal breaker.
Maybe try the version with the overclocked gpu. I think this can have a big impact, I mean on the PC most of the work is done by the gpu so I could be that it's similar on our phones

it's said that the difference is so minuscule, the 512mhzoverclock isn't worth battery loss. I'm not talking about relative to Franco, the device's stock gpu frequency is 304. But if you see it that way, to each his own.

Unless the GPU has built-in hardware encoding or decoding for the particular codecs involved, and it's actually being used by the software, it won't play any part in video rendering.
Interesting.You could try the same with Trinity .

Definitely, gonna try and post results later within this week. Very busy at this moment.
hello:
my evo 4g battery lasts less than one day.
I googled but didn't find any good suggestions.
if I flash a custom rom to remove all bloatware, does it help?
thanks a lot.
I would also like to know this.
Sent from my PC36100 using xda premium
This should be in the Q&A, I Belive but to answer this question, a lot of things affect battery, first a old battery of course won't last you so long. Second are you running a custom Rom? And overclocking it with like CPU tuner or simmliar.
Are you running your brightness high,is your 4g on all the time, are you using music or social media a lot, playing games and so on.
That being said, moat customs roms can improve battery life to a degree, aswell as the kernel you use and what setting you are running it at, for instance I m running my custom Rom with underworld v8 no halvs sbc kernel
And my governer Set with ondemand at 769 max or something like that, I don't run 4g when I have WiFi, and my screen brightness is set low unless I need it brighter I will change it, I also have a lot of tweeks in my build prop, which a lot of other devs do aswell to help with battery life.
There is a nice section in these forums that explain governers you should read it, you will learn a lot.
http://forum.xda-developers.com/showthread.php?t=1663809
I get about 2 days with normal use on my setup.
Hope this helps.
Also its always good to wipe battery stats when flashing new roms, also discharge battery fully and then charge it fully.

Custom roms usually have better battery life. On average I get the best life out of the sense 3.5 roms with the aggressive lionfish kernel but the kernel does not support ext4. Sense 3.5 also needs sd-ext partition to run and when changing kernels you must manually mount the data partition before you flash the kernel.

The stock battery doesn't last very long, I'd suggest getting an extended life battery if you plan on keeping your EVO for a while.
I use my evo for music now,I thought I lost it for 2 weeks, this is airplane mode ,running cm9
Underclock, dim brightness, install a lean ROM and take off services you don't need I.g. 4G or 3g.
Other than that. Extended batteries are the way to go.
