Set cpu with stock kernel droid incredible

I just rooted my incredible and I'm using the kernel that came with it stock. I disabled perflock and I left the max speed to 998 and the min speed to 245.
When I'm not doing anything on my incredible, I see that the speed constantly changes from the max to the min. Not even one second passes before it just goes back and forth, back and forth. Is this normal?
Coming from the d1 where it would stay at the min when idle, I'm not sure if what's going on with my incredible is normal.

Yes that's normal. For better battery life, I'd try a kernel with smartass governor. It spends more time on the lower frequencies.

Switching to a different kernel will give you the ability to overlook//underfoot the system needed.. this in turn increases battery life.. kingklick, ziggy's, chad's kernel are all well known kernels.. you will want to play with different kernels.. not every kernel will be stable to overlook to certain speeds on certain Rom's.. switching kernels is almost as addictive as switching roms.. always nandroid before flashing anything..

Will those kernels work on my rooted stock incredible?

Yea! By stock i'm assuming all you did was root. I am currently running SkyRaider 3.5 Sense along with
"2.6.32.26-ubcredujuerbek-12082010 [email protected] #11"
I will edit with links to these two items.

Chad's Kernel - Incredikernel
My phone runs amazingly fast with sense but yet, even with heavy usage (Texting constantly, on the internet, gmail, even Fring) I can go an easy 24 hours on one charge. If my phone stays screen-off idle I could last at 95%-100% for several hours.

Yes, all I did was root.
Does the chad kernel provide wireless tether and will i still need to disable perflock in setcpu?

the non stock kernels all disable perflock already, you do not need to do it..
flash the kernel via clockwork, and you are set.. jump into setcpu and adjust some settings and add profiles.. you'll be golden..

Not quite. I believe Lou's has some tweaks within perflock, so disabling it would lose those.
And most kernel devs, particularly Lou and the ones who use HAVS, advise against using SetCPU. I'd check with your chosen kernel thread for details.

Also, I wouldn't 'set on boot', at least till you find frequencies that your phone can handle safely. Otherwise, you'll get a 'crash' loop, where your phone starts up just fine, but once you go past the initial lockscreen it'll crash and reboot. Very annoying...

what rager said... ive put on kernels and ran em high only to get a "boot loop".. its tuff to get out of cause you need to get back into setcpu to scale back otherwise it keep on going.... i learned to put the setcpu app icon on my main screen so i can get there fast to scale back..

http://forum.xda-developers.com/showthread.php?t=866736 can you install these with the stock rom. i wanted to experiment to get better battery life but didnt really want to install a different one.

Yeah, if you let it boot loop too long it'll hard boot, which is where the phone cuts off completely. That has happened to me, and it ruins apps.

[Q] AOKP w/ Ktoonsez kernel CPU stuck at maximum frequency

ive been running ICS since i got my phone, the battery life was horrible until i fixed the power profile, but even after that my phone's battery was not that good. i decided to flash CM10, then i switched to AOKP, both of them are awesome, but i noticed that the battery wasnt that good either, i got the ktonnsez kernel. i tried other governors, they all stay at maximum (1512MHz) after about 5 minutes of a reboot. i tried basically everything, reflash every thing, wiped everything possible. I need help plz, i wanna enjoy my S3 without worrying about the battery dying.
its all normal when i start my phone, but after 5 minutes it just stays at maximum CPU...idk why plz help im on galaxy s3 ATT i747M...i searched everywhere but still didnt find the answer

If you flashed kt747 you need to use the ktweaker app that comes with the kernel. When you find this app you need to check the two boxes into general settings

Have you solved this yet?
Try a different governor. Personally I use on demand and noop for the scheduler.
Make sure you don't have any other overclocking programs which may be conflicting. I used to use SetCPU but with the toonz kernel I get Ktweaker. So I got rid of SetCPU.
Funny yours is locking at maximum. Mine used to lock at 96Mhz and run like crap. The above method worked for me. Don't forget to make sure your running the most updated kernel, wipe cache/dalvik/fix permissions.

Tyvm, i did what u told me and its working for now, i was using ktweaker the whole time, but i like to check my current speed in ROM control, idk why maybe cuz the numbers are bigger? ;P im still not sure if its going to work for a long time, i did a reflash yesterday, i charged my phone at 100 percent last night, and it was sitting on low frequency, when i woke up, i was suprised to see a 6% drop of the battery, leaving me 94% left. but the speed was at 1512. and cell standby was using most of the battery.

TY, ive tried switching governors before and it didnt work. But when i tried this morning, it worked... really strange.
Idk if it will last long, my phone likes to jump around from normal to maximum without me even touching the phone

Use ktweaker instead of the rom settings. Go to the performance section in settings and disable set on boot. Then, go to ktweaker and set as "apply settings immediately after boot". Once you're done, set to whatever you want it to be.

[Q] battery drain problem JB back to stock.

i updated to jellybean LI8 from stock t999 LH2 version, but because of super heavy battery drain i flashed it back to LH2 thru odin.
However i still get same heavy battery drain. i use up 10% every 1 hr just with screen on. before i used up about 3~5% for 1 hr.
i was able to get about 14~16hrs with normal use before, but now i dont think i can even get 10hrs.
it seems that the sim card area gets hot whenever the screen is on, and cools down when off. before flashing my phone was never heated
unless i was playing heavy graphic games..is there a way to completely flash the system files? or to fix this problem...pls help. thanks

Your numbers don't make sense. Need a screenshot.

I also observe the battery drain.

Give it a few full charge/discharge cycles to work itself out.
How did you update to jb? How did you revert to ics? Custom roms, otas or full firmwares?

yes the screen % is fine so i dont know where its draining the battery...
i think something wrong with system file because my phone really didnt get warm just from having the screen on.
is the method i reverted to ics correct? or is there another way to completly reset/overwrite my phone back to stock?

If your phone is working, your method wasn't incorrect. If you flashed the stock firmware through Odin, that's as virgin as it gets.
Battery Info and KakaoTalk are obvious culprits. Tell me about your wifi situation. Are you connected to a wifi network?

yeah usually i leave wifi and kakao talk on most of the day but it doesnt drain battery this fast...it just messed it up after the jellybean update., it was 100% this morning, 4 hours and now i got 60%. usually i would probably still have around 85%+

I'm in xquizit v26 and observed that I'm not getting a deep sleep and the battery drain in less than 5 hours. I reflash the rom with full wipe and still have the same issue. I step back and investigate what cause this problem. It seems that when I flashed the kitchen v6 with open vpn cause not to have a deep sleep. With out the open vpn I was able to get a deep sleep. On the first cycle I was able to get the 15hrs battery life. I will continue to observe this because the battery behavior can only be observed after 3 days.
I tried to post this in the ROM section but XDA wont allow it because I only have less than 10 post.

You should pm this to wildchld. As far as i can remember this is the first ive heard of it and maybe the same for others.
Search the thread first to see if anyone else has reported. If not or if you think you have information to add shoot him a quick pm.
If you dont want to let me know and ill get the info to him so we can test it out.

If you can go without, try uninstalling those two apps and see if it settles at all. Also get cpuspy to see how often the phone goes into deep sleep.
Sent from my SGH-T999 using xda app-developers app

okay so i jus instaled the cpuspy and saw that theres a lot of deepsleep so i guess theres no problem..?
and i think its not the app but the thing with screen. whenever the screen turns on, it gets hot and the batt uses alot..
i tried re-flashing using odin while ago but still the same.

I would suggest flashing wildchlds XquiziT or DJintrigues Frosty JB. They both have done very good jobs at getting more out of your battery while still remaining stable. Being on the full stock leak i doubt you will easily find a way to acceptable battery life. At full stock i kind of remember LI8 being one of the worst for battery.
There are actually multiple causes, some depend on how you use the phone.
Another thing you can do to help hunt it down is get Better Battery Stats.
Also in Settings > Dev Options check show cpu usage and itll tell you what processes are using the processor in real time. You will likely see 2 or more that seem to stay at the top of the list.

i checked the XquiziT's ROM and i think lots of people are saying the battery problem was solved so mayb ill try it with this one, however when i went over the posts it seemd that theres prob with the kitchen? thingy and they took it down. is it possible to jus flash the XquiziT Rom without the kitchen features?

Yes you can flash rom without kitchen. Hes actually working on a new release hoping for today I believe.
Kitchen was taken down due to possible bricks when using wallet and mobile odin.
Also, battery problems are not 100% solved in either rom but are close!

hey thanks for the replys...
ive tried to flash the v26 through recovery boot menu but it says E:verification error. i think its because i flashed back stock by odin, how can i solv this problem?

Have you reinstalled twrp or cwm? Stock recovery wont flash that.
Sent from my SGH-T999 using xda app-developers app

Remove the battery for 5 min...and then check for the drain. Mine fixed itself up this way.

okay so i installed twrp and did the install but still same prob with the heating battery lose. i will try few more wipeout+install and the battery takeout thing too and post up

[Q] processor keeps going above max cpu setting?

Hello, i am new to the android world, and am loving it. Ive tried a couple of roms, and decided to stick with Liquid Smooth Jelly Bean Rom. My only problem is this:
i have set the max frequency for the processor to be 1512 mhz(or lower sometimes), but sometimes it keeps automatically setting itself to 1900mhz, which i do not want. Is there a way to set it so that it will never go above 1512?
btw i am on 3.0.45 leanKernel if that helps.
Thanks

Check mark the set on boot box and restart phone right away after you change it back to 1500mhz.

Depends what kernel you're running, some kernel apps let you lock the frequencies so they cannot be changed by apps. If an app needs to run faster it will bump up the speed, so might want to check into that. Works on KT747 Kernel (Ktweaker).

Here's the link for the KT747 Kernel http://forum.xda-developers.com/showthread.php?t=1756776 . It works with all AOSP (CM10, AOKP etc.) aswell as most touchwiz roms. I've never used Liquidsmooth so Idk what it's about but this thread should contain information about which roms it is compatible with. If you have any questions I suggest starting a new thread about what its compatible with or asking directly in the thread. Good luck Always flash Rom before kernel.

overclock t989

hello, that´s my concern :S, i want to do it but i need to know what´s the best way to get it done, i hope someone can tell me, i already installed CM10 with jelly bean 4.1.2

First install kernel zip from recovery. (If using team win recovery there is no need to darkside wipe.) I use flapjaxx kernel and its great. Can be found in development section.
Get "system tuner" from play store.(free).
I clock mine at 1.67ghz. Good performance and battery life.
If you got CM10 installed this will be easy for you.

Well, I didn't do it with Team Win Recovery so i guess that i had to use darkside wipe after installing the kernel. The thing is that it kind of bricked my phone :S, any ideas?

If its bootlooping at boot animation, you need to dark side cache wipe after installing. If you don't have the cache wipe already you may have to restore from your nAndroid backup(assuming you did that before kernel install), then get darksidecachewipe.boot to recovery and install kernel, then cache wipe. Should boot after that. May take longer to boot the first time.
I went through the same thing the first time. But I could not even install cm10 without DS cache wiping, which makes me wonder how u got cm10 running without Dscachewipe. Did you follow install instructions on page 1 of flapjaxx kernel thread?

Alright, now it's working , I just did what you said. I set it on 1.67 GHZ with System tuner App. could you recommend any other Tweaks?

Play around with your clock speed. Go a little higher if you want. Personally I like 1.67ghz because its a good compromise between battery and performance.
Antutu benchmark @ 1.67ghz=7806
And @ 1.83ghz= 8050
So there is a performance increase, but for daily driving I think it unnecessary.
I flashed GPU script also from flapjaxx, but I don't see much gain because I don't need all that much graphics performance.
I'm also running the v6 supercharger script @ 25% super charge. Search for it on xda. Huge gain in performance with this script.
You can also try "pimp my ROM" for various tweaks but I didn't much care for it.
How's your GPS running?
Only problem I'm still having.
Good luck. Pm me if ya want.

hehehe thanks!, now i have a small issue... now the capacitive buttons delays on turning on when i overclock it :S, why´s that?

Try playing with the options in "settings-advanced- sensors". I keep BLN off. I think it does not let the phone deep sleep as often. Which consumes more battery.
Sounds like us got it all figured out. Don't forget to backup in recovery. Saved me many times.
