Root + OC widget = 2 days of battery??

Ok, I am suspicious of all things people post at first until its verified, but here is the link of someone who says its fact.
http://androidforums.com/all-things...clockwidget-insane-battery-life-40-hours.html
My question, is this legit and if so are there any potential pitfalls from setting the EVO like this?

Looks pretty interesting, hopefully some more people will test this out.

Is there a log to verify it is changing the CPU speed? I know there was something like that on the Pre, but it didn't always set the CPU speed down.

Testing
Just installed it. Will post my results in the next few days.

Did you use toast's method of rooting or unrevoked?

There is a notification option that tells you every time the CPU changes frequencies.

Which root method did you use?

I am also trying it out - I'll update you all in a couple days. I have it installed, it says that the frequency change was successful, so I guess we'll see...

Whats the app that tells him 21 HRS?

I am using toastch root with his froyo rom. Overclock widget doesn't officially support 2.2 yet, so my results might be worse than 2.1 stock. Worth a try anyways.

I might go ahead and install unrevoked on mine to try it. I am getting great battery life as it is now.

I believe that neither SetCPU or overclock widget will work properly unless you use a kernel with my patch.

WIthout the patches, what is the application actually doing if anything?

It's setting the speed... Then the speed reverts itself immediately because of HTC's modifications to the kernel.

Okay, I will not worry about using it then. I guess the phone just has that good of battery life.

Battery Indicator...In the Market

hahah i got a pic of my hero on a 3days and some odd minutes off the charger.

So this app does help? Or does not? Using it I'm at 4 hours at 60%... Not much use, a few texts and a few phone calls, and like 3 webpages.

help a noob out?
Can anyone explain how one goes about installing this patch? And maybe use small words for us rookies?

set cpu yes or no?

okay, I used to use set cpu... then I read that set cpu actually kills your batttery, so I stopped using it.
currently i'm using VirusRom anthraX RC1 with 2.6.32.15-king-havs-OcUV-aosp
should I be using set cpu?

+1. also, the first time i used it, i oc'ed all the way and instantly got a reboot. is this the starting point in the infinite reboot cycle? i had that problem happen to my last evo.... not fun

I am thinking the dconfig file virus has will work on Anthrax..use it on Airborne and REVolution roms of his, along with SetCPU, and getting good results.

Its entirely up to you. If you feel you phone isn't fast enough for you then OC it. SetCPU is required to overclock. If you don't overclock then you don't need setcpu. You will most likely have better battery life if you don't overclock. I run mine both ways I oveclock for a while then run stock for a while. Battery life is better at stock speeds.
My advise when playing with setcpu is to uncheck the set on boot just encase you set it too high. Take baby steps don't just jack it up all the way. Also I think some kernels can use a configuration file, I don't know anything about that.

installing incredikernel on cm7?

Hi guys i just installed cm7 on my incredible and i was wondering if im allowing to install incredikernal?
also im wondering how to wipe battery stats and when to do it
thanks

I've used other kernels with CM before and it works fine--if that's what your getting at...
As for battery stats, you should be able to do that from recovery. With clockwork mod, its under the 'advanced' menu.

If you are talking about this kernel
http://forum.xda-developers.com/showthread.php?t=848453
Yes that is made for GB roms like CM7. As for wiping battery stats, the debate is out as to whether or not that really does much. I have never noticed anything extra from doing it, but thats my experience with it, your experience could be different.

Yeah its good to put min at 128, helps the screen off profile and with battery life. The max you can make whatever you want, but once you go higher than 1.113GHz then you start going into unstable territory IMO.

Just note that a few users have reported issues with the 128 setting. I haven't experienced any problems getting text messages or missed calls and I'm using this kernel with the 128 setting but just keep it in mind if for some reason you find yourself missing texts and/or calls.

[Q] cm7 and setcpu update

[Q] cm7 cpu setting or setcpu?
well atm i am running an evo 4g with cm7 and i just switched my kernel to savaged zen and it's running great. my phone was rebooting on its own w/ the regular cm7 kernel i think its b/c i was using setcpu and people are saying it messes up cm7.
so i was wondering if anyone knew if i can use setcpu with cm7 and savaged as the kernel or if it's possible to make profiles on the cpu settings on cm7 i saw some1 post somewhere that you can but they never explained how.
p.s. please also visit this thread on battery life

AFirst of all, all SavagedZen kernels are Havs kernels (as far as I remember, I'll double check in a few). Anyway, if you are using a Havs kernel, changing cpu settings is pointless/counteractive. I would either leave the settings alone or switch to a no-havs kernel. You can check in settings>about phone.
EDIT: However, if you must mess with the settings, you can find them in Cyanogenmod Settings under Performance Settings. I don't know of a way to set profiles from that screen, though - only max/min & governor.

hi i have an evo running cm7 and i had setcpu and my phone kept restarting however i looked up setcpu again in the market and it said that they just ran an update to stop the problem with cm7, does this mean that setcpu is better to use than the cpu setting in cm7?

You shouldn't need setcpu use the cpu setting in cm7. They put it there for a reason, those guys are sharp!

I still use setcpu because I like my screen off profiles etc. You should update your setcpu if it prompted you to. I think the latest changes were for cm7/GB.

I believe the SavageZen governor is a specially tweaked/optimized version of the SmartAss governor.
And if you use Smartass/SavageZen governor, I think it also automatically undervolts when sleeping, and essentially mimics what a screen-off profile in SetCPU would do.

In CM Settings, go to Performance Settings & then CPU settings. Under available governors choose SavagedZen or Smartass. I'd try them out & see which you like the most. I prefer SavagedZen, I seem to get better battery life & performance.

Personally I have never needed a task killer while on CM7, so I am going to recommend against it.

Well I had talked to someone else that is using it like that and they said they get amazing battery life
Sent from my PC36100 using XDA Premium App

I say no toward any kind of task killer. First of all, they're pointless. You're killing stuff that isn't using any power to begin with, which then restarts anyway. The task killer itself is actually doing something, running on a set schedule, where as the tasks you're killing are just sitting in memory for faster opening.
It bugs me that even the techs at Sprint recommend it, so every person that doesn't know anything about how their phone works thinks it's necessary. Then in the market for every clock widget you see everyone going "like zomg the clock doesn't keep time your app sucks 1*" because the damn task killer is killing it. That's if they can even figure out how to use it & not complain that it "won't open", despite clear instructions on how to put a widget on your screen.
Sorry, totally went off on a rant there.
But yeah, stay away from task killers & let Android do its job. You don't have to have a ton of memory free for your phone to run perfectly fine under normal usage. I don't notice a difference between 300mb & 50mb free. If you don't worry about it, you won't either.
Free memory does not equal more battery.

No. Memory has nothing to do with battery.

(Question)(need helpp)

I'm using the setcpu app and whenever I apply a "when screen off" profile and put my phone to sleep it won't turn back on. I set it to 200-400mhz and it doesn't turn back on and I think the govenor is conservative.
I am running randomrom pheonix with genocide 2.0 kernel.
Can anyone tell me what they have their profile set as or what is a good low value I can set my phone to so that it still runs but doesn't waste too much battery life while its off. Any kind of help is appreciated.
Sent from my SPH-D700 using XDA App

Don't use profiles
I wish I could be of more assistance, but basically, I remember many of the more experienced forum members here suggesting that you do *not* use profiles with SetCPU on the Epic 4G.
I am running the Genocide 2.0 kernel on my Epic with SetCPU set to a max of 1120 and min of 100 MHz, with no profiles set and the governor set to conservative. Haven't had any issues.
Also, I use a widget called Temp+CPU PRO that dynamically shows you the clock speed of the CPU, so you can tell when it's at 100 MHz and so forth.
From what I've seen, the speed of the CPU ramps down to 100 MHz on its own when the phone is idle.

Oh.. well I have never seen that.. I heard ppl talking about setcpu is better than voltage control so I thought it was cuz of the profiles.
So about how many hours do u get out of ur phone? What rom r u using with that kernel?

There are a lot of good posts on here about maximizing your battery life. Most of it requires some functionality to be sacrificed, so it's all about your personal preferences.
Our AMOLED screens are purty, so even though I keep mine dim to save battery, once in a while, say when watching a movie on the phone, I'll crank up the brightness all the way to make the visuals pop. Do a few searches, read up, and then tweak, tweak, and tweak some more until you find that "sweet spot" that works for you.
Of course, hooking yourself up with one of those monster 3500 mAh batteries wouldn't hurt, either. Just sayin'

And idk how to use tweaks really well I found this battery tweak thing and I believe all it really does it change the mhz the phone runs on but I could b wrong
And I used supercharge v6but idk if it works I don't notice any changes.
So now I just changed to eh17 modem and removed all apps I don't use and only have a few. I froze the thingsi know waste battery and I don't have nothing thatuses the battery I think.. so is there any tweaks u know r good?

Don't they cost like $70???

I wouldn't use the screen off profiles. You only would need them if your trying to have your phone never go into deep sleep for some reason. Not to say the settings would cause this, but your phone should hit deep sleep after 10 or so seconds of screen off making this setting quite useless. Also if your running genocide you need to be using on demand! You can set the throttle up % in the advanced tab of setcpu. If you wanna utilize profiles what I do is set it to throttle down the cpu as my battery dies. Saing juice for those crucial lower percentages.

I'm saying don't bother with the screen off profile, first of all. Secondly don't run conservative with genocide! Its geared for ondemand (unless your trying to save your battery by not overclocking at all) and ondemand is configured by going into the advanced tab and configuring the usage percantage of your cpu to switch to the next highest frequency at a certain percentage. I use 98% and I get pretty darn good battery life. I don't know if it helps or not, but I also set powersave bias on 25. Just post if I'm still confusing you.
Cd's or tapes?

No I get it now ur talking about the up threshold right?
I flashed this battery tweak and I went to check it right not the up threshold is set to 95 I guess the tweak changed it cuz I remember checking it before and everything said -1. But thanks I get it. So if I had my phone set to 200-1200mhz and ondemand and when I have a high battery level I higher the thrshold and as I lost battery I lower it...?
