A few questions from a noob!! - EVO 4G Q&A, Help & Troubleshooting

I have a couple of questions on my rooted Evo.... I rooted my wifes Evo and my Evo using the newest unrevoked. After rooting I flashed Myns warm 2.2 rom along with kingx kernel# 9... I also flashed the collins ph battery tweak.. The first couple of days we had phenomenal battery life, as well as the phones being fast as hell... My question is now the phones seem to be running at a very high cpu usage percentage I.e. anywhere from 60-99% cpu usage.. Is this normal?? The battery life is also terrible now, and I haven't changed anything since flashing the rom and kernel. I was using set cpu and after doing some research I found out that set cpu interferes with the battery tweak so I uninstalled.... What should the normal cpu percentage be at?? Any help would be greatly appreciated!!
Thank you in advance!!

use a task killer such as "advanced task killer" to kill unwanted apps that run in the background. also, i have setcpu set to over 1GHZ max and 576MHz minimun and honestly, i cannot tell if it makes a difference in battery life, alot of these things you will have to find out for your own because each phone is a little bit different for each user...

there are a few things that can cause this. it is likely one of the apps you have installed is staying on or you have a run away process. The sue of task killers is debated as being a good idea or not i will let you make your own choice on that but i will say the task killer wont fix the problem it will just try to cover it up.
The problem is that the true fix will probably take some time and find and correct. If it is and app one tool that may help is the paid version of system panel. it will help monitor which apps use the most cpu/battery time and it shows you all running apps. you can also use system panel to kill your apps manually (by pressing the kill all button or killing each individually). I have used it help trouble shoot and monitor my battery etc and it has been helpful to me however i will say it doesnt always provide enough information to help you figure out what app is causing the problem when that happens i usually assume its a system process causing the issue.
as for normal it i going to very greatly depending on the apps you have running. when just sitting here watching it mine is normally 8-15% and occasionally goes as high as 20.

Thank you guys... that system panel is awesome!!

Need educated!!!

I need educated on a few things, I'm concerned with the performance of my phone so I have it rooted and I have installed system panel to monitor things, autokill memory optimizer for ram of course as well as watchdog to alert me if any apps are outta control. Am I crazy for having these or is it a good idea? Also is there anything better I should use rather then what I already have? I just want my phone to run smooth and my battery to last bc I use my phone all day long

A lot of that is unneeded. I have System Panel, but only use it if I'm having problems with an app. Rarely is there a use for watchdog. On stable ROMs, I've never seen an app get out of control, and rarely on betas. So it justs sits in the background eating battery itself. Also try, using a stock speed, undervolted battery with SetCPU. If I'm trying to make mine last, I have a screen off profile of powersave 384/245, and regular of 700-800ish (I forget)/245 conservative.

ok thanks, i installed setcpu and have two profiles set, one for when screen is off with settings similar to yours and another set to when my battery is >30%. could you please tell me what the governor options of on demand, userspace, or performance mean ?? also should i set priority's to anything other then the default 50 % ? thanks for the help

[Q] Better battery life (Kernel Confusion)

Recently i've ventured into kernel threads wondering how i can get better battery life on my G2. I consider myself pretty well versed in roms but Kernels are a whole new animal for me.
I have read so many threads im becoming dizzy. If i have to flash a kernel for better battery, which one? I dont have demands for a faster phone. Most of the threads about kernels i have read are all about getting a faster clock. Im fine with the speed of my G2. I just want better battery.
Can some one provide me with some literature on the subject, point me in the right direction, or even better, answer some questions for a noob in this particular subject??
What Kernel to use?
Can i flash over CM 6.1 Stable?
Do i need to wipe before flash?
Any assistance will surely allow me to sleep better at night.
Thank you in advance.
I can tell you im running virtuous 7.2 i find pershoots kernel the best for battery.

If you want great battery life, don't use a sense rom. They're battery hogs as it is. Stay on CM 6.1 and flash pershoots latest kernel. Get setcpu and set a profile to 245/245 when the screen is off.
With these settings I get awesome battery life and I'm overclocked to 1497.

Oh ya i learned through trial and error to stay away from sense roms.
Can i ask you why you overclock? I dont find myself in any moments where i think the phone should be going faster.
I can flash pershoots over cm with no problems?
Can i get a link?
thanks for the response.
Well i lpike sense but only when its ocd sense too sluggish on stock g2 speeds. Also even with ocing and runing sense my bat last just about all day. It sometimes needs a shot a juice if im useing gps or playing a lot of games but thats it.

Decent battery life on my G2.
I'm running htc sence on mine with the pershoot kernal and cpu tuner.I have tweaked profiles and my battery life is better than b4.Example, i took it off the charger(ac) yesterday morning @ about 9:20am & today Thur, i checked the [email protected] 11:50am and my battery is only @ 40%.(1 day,3hrs & 31min's later)not bad.That's WITH moderate use.

So whats CPU Tuner? Do you have some suggestions for how to tweak the profile? Can i get a link to the pershoots thread? Is this the right thread? --> http://forum.xda-developers.com/showthread.php?t=847672
Do I have to wipe before flashing and then reinstall cm over it?
When I went into SetCPU, it always kinda confused me. That could be why I was never interested in overclocking.
I realize I have a lot of questions. Im just a careful and thorough person.
Simple.
@dangabob13...Don't worry about all the questions i'd want to b super carefull as well.First, cpu tuner is a free app in the market much like set cpu except u get more options as far as customizing your profiles.Second you can find the pershoot kernel right with in rom manager.Just go to the download rom section & its the 3rd one down.I didn't wipe and i haven't had any problems.The reason i switched to the pershoot kernel was because i was having problems waking up the screen with HTC sense and the kernel it came with.This fixed the issue for me.No need to b confused it's actually pretty simple.My profiles for cpu tuner are as follows:
Under the "Current" tab: i have the governor set to "conservative" i have the cpu o.c to 1094 MHZ.No need to go crazy over clocking i find this to b fast enough for now. The rest of my profiles:under the "profiles"tab,
Performance:Ondemand-Max:1094 Ghz,Min:768Mhz.
Good:Conservative-Max:1094Ghz,Min:768Mhz.
Normal:Conservative-Max:1094Ghz,Min:768Mhz.
Power save:Conservative-Max:1094mhz,Min:768Mhz.
Screen off:Conservative-Max:768Mhz,Min:768Mhz.
Extreme Power save:Conservative-Max:768Mhz,Min:768Mhz.
Keep in mind i also have wifi,blutooth,sync all disabled as well.I'm not saying this is guaranteed to work for you, I'm simply stating what works for me. Good luck i hope this helps.
Quick question....doesn't CM6.1 Stable have the pershoot kernel already? Also does the Pershoot kernel the one that goes to 1.8Mhz?
Not that I'm interested in going that high, but just wondering.
I OC for games mainly, but also to watch tv and movies, the extra umph really helps. My setup on SetCPU are:
Temp>40.2*C 368 / 245 Powersave Priority 100
Screen Off 245 / 245 Powersave Priority 90
Charging/full 1497 / 245 Interactive Priority 85
Battery<10% 268 / 245 Conservative Priority 80
Battery<30% 806 / 245 Conservative Priority 70
Hope this helps.

I dont have a conservative option under the Governor dropdown. is that important. Otherwise i duplicated your settings. Boasting 27 hours of up time and 40% left is bound to make me jealous ill test it out. Thanks again.
That's strange is your cpu tuner app up to date? I also wanted to mention that my screen brightness is set to 20%,heptic feed back is turned off and so is vibration. Along with a few other battery saving options you should see a difference in battery life.Obviously results will vary.

Ha its so funny. I have the same exact settings. i took a look around and turned off all that stuff. I keep my GPS on because it only uses battery when its being used. But i turn off wireless locations so that its not always trying to centralize my location.

Do we need SetCPU apps when we have CM 7.0.3 Stable ?

I am a newbie on rooted phones. Just rooted the phone to CM7.0.3 Stable and found out that we have a setting to change the Govenors, currently set using SMARTASS with 245/729.
One question, is it nessesary to install apps such as Setcpu to overclock? or it is just adequet to use the setting in CM7 ? Will both conflict each other? Many thanks
Its useful I think, because you can setup CPU speeds for certain things, such as when your screen is off or when the battery drops below a certain threshold.

depends on you need dude. playing games/ watching videos/ hearing music/ simple phone usage/ battery conservation etc. stock one dont have profiles. but 3rd party like set cpu have it. so that it auto switches profiles according to ur present phone status.

SetCPU is much more useful than the cyanogenmod CPU functions, I did use the cyanogenmod one but I didn't see any changes

yes, the good things are the profiles! but I'm not sure if underclocking the processor really saves battery since i've heard that its just a saying/placebo

Yeah I think your right, strangely enough I think it's the same with overclocking, I put mine up to 700ish MHz and the battery still lasts just as long, I expected a reduction in battery life!

Battery ??

I'm down to 25% after only nine hours and I don't understand why.. Lol I'm confused for real I thought rooting would improve it. And I've only actually used the phone for probably 50 minutes. Any help or suggestions
Sent from my Dinc running cm7 with incredikernel
search around for suggestions. to start off control data usage,sync control,use auto brightness,turn toggles off you don't need uninstall or freeze apps especially those that run in background for no reason that fail to cache. use a different kernel. do some undervolting. overclock and underclock when necessary.use tasker to setup screen off/on profiles for different min/max frequency ranges and governor selection,use apps to monitor usage such as drain guard and cpu spy. check apps that hog too much unwanted usage. the list goes on. if you do your research you could save yourself 70% of battery usage. using tasker alone saved me around 30%. for example my phone is fully charged before bed,I sleep about 6-8 hours while listening to music and I have about 80% once I'm awake.nothing on besides the phone's cellular radio,no gps,no data on,no 3g,no wifi,etc. not even airplane mode so sms isn't queued all night. tasker can also auto turn off gps once gps based apps are killed so it's not always on,plenty of threads on battery saving tips,majority aren't all device specific so they're universal tips

agreed rooting won't do anything for your phone unless you put it to good use (uninstalling bloat apps, loading a custom more battery and performance efficient kernel, same with a better ROM, as well as countless performance/battery mods)
There are so many ways to improve performance and battery life on your phone with root, but you have to actually apply them to your phone.

well I probably worded that wrong. There's mods you can do that will improve battery performance.
Check here and scroll down to the bottom where it shows performance mods:

As a personal suggestion.
ROM: CM7 latest nightly
after you flash the ROM, flash the latest Gingerbread [AOSP] kernel:

2.6.38.8 incredikernel 10/08/2011 (3277)
Then apply:

Then proceed to uninstall the crap apps you don't want.
Then customize the mutha lovin hell out of your phone with these apps:

before i flash adrenaline am i supposed to wipe anything?
Rooting doesn't improve battery life. usually a custom kernel or rom will improve battery life. It all depends what you are running in the background. With Nil's Gingersense 3.5 (2.2) and tiny's latest kernel I am getting unbelievable battery life. This is in part to how well both of these things work together along with the removal of all the bloatware. I have found that if you run Yahoo IM, it tends to kill your battery faster as well. Make sure to set most of your sync options to manual or every few hours as well. It won't impact your gmail or gtalk settings.
I understood that just rooting wouldn't change a thing. I just miss worded it lol. I was already running cm7 and incredikernel. I just hadn't realized I had 2 apps running in the background killing my battery
just flashed tinys last night and waiting to see how it works. I have two batteries and one lasts much better than the other and they have both been treated the same as far as charging and discharging....

Improve battery life?

How can I improve the battery life of my play with rooting? I don't want apps that kill every background app though as I may want to go back but it would be killed

Assuming you're on a stock rom theres a couple things you can do. The easiest would be to root and use Titanium Backup to either freeze or remove the bloatware from your phone as it runs in the background and causes drain. Another would be to look into using some of the tweaks found here:
http://forum.xda-developers.com/showthread.php?t=1227269
Another option is to try running different firmwares, personally I found the older ones to give me better battery life while others found the oppisite to be true, so try a few till you find one that suits you. A more extreme approach which will yeild far better results is to unlock your bootloader allowing custom ROMs and kernels. With custom kernels you can over and underclock your phone while choosing more effecient governers (like the smartass governer). You can also undervolt your phone which will probably lead to the biggest saving. Custom ROMs can also increase or reduce your battery life, again, try a few. Personally I run at 1.5ghz on smartass, undervolted as much as possible with version 7.1.0.1 of CM7 and have great battery life. Also keep in mind the obvious tweaks such as turning off wifi, gps, 3g, brightness, etc to prolong battery life.
-EDIT- Also on older firmwares there was a problem with using "Automatic" under time and date where it would cause a lot of battery drain so you may want to turn this off if you think it might be a problem
Thanks, but I'd rather not root my phone yet. Thanks anyways

I would say update to .62 firmware it should be up for all around the world yesterday i updated my arc s to it.I was setting up the phone after (flash before the update) and i had to set up everything again and my battery is still on 70% from yesterday (im talking downloading apps,connectin accs and stuff,like 3-4h of usage and around 8h on idle while i was sleeping).My phone isnt rooted and its with stock rom and stuff
I use juice defender ultimate. It allows me to easily get a days usage out of my phone when before i barely got a day
