I was browsing my system info and it seems my cou is running at 800mhz? Do u guys also have this as the standard

I mean when I view the system info in Quadrant, it says the cpu is underclocked

samsung built in an ondemand power bias, it will scale up to 1ghz if needed but will most of the time sit comfortably at 800
Cpu speed is self throttled. It won't run at 1gz unless required by whatever it is you are asking the device to do. This is to conserve battery usage. Ie: The phone doesn't need to run at 1gz to play solitare smoothly but might to play a video or 3d game.
Edit: I see someone beat me to the answer.

Currently at 102.2F as reported by setcpu widget while plugged in and using it for the past half hour or so. Seems kinda high to me, what's everyone elses experience?

Well when its plugged in it will be warmer than normal. Right now my phone has been on with constant texting and random other usage all day long and I am at 80.6 degrees
My phone stays in the mid 90s and early 100s with regular use. It only gets in the 80s if I leave it completely alone for an hour or so.

I stay mostly in the 80s and can get into the 90s with heavy use. Don't think I've ever passed 100, but there's a chance something like psx4droid could have pushed me up. I average about 86F.

Do you use the SetCPU profiles? You could set one to underclock the processor while charging.

I do, its set to 800mhz when charging. 600mhz if it gets above 104F regardless of charging or not. Leaving it alone on the charger for the last half hour the temp shows 92F. Just firing up Xda app and typing this out the temp has jumped to 98F in about a min of use.

Are you guys using SetCPU for profiles and overclocking, or are you just using it for checking temps and current speed?
These are the droids you are looking for.

I was using it to check temps for this but I use 2 profiles, which may help my temps (def helps my batt). The default profile is 1000 max, 300 min, on demand. The other is when my screen is shut off, 300 max, 300 min. I've found this has saved me a pretty sizeable chunk of battery. I tend to listed to music 7-8 hours a day and while it doesnt need full CPU it will use it if it gets the chance. Restricting the proc to 300 off has never caused any issues and I can get from 8am - 4 or 5pm staying over 70% battery I have the unstable apps overclock and used it for a while, but kinda came to the conclusion that I can't really justify needing to overclock yet as I never see any lag. I guess if I run into any lag at some point I'll prob clock back up to 1.3 or so.

I did overclock, but it ran way too hot, like 107F during normal use and didnt get below 100 dormant. 1gig is high enough to me. I have it set to underclock when charging or when below 50% battery or when above 104F.

Only other idea I have is downloading Droid Overclock and try running at low or ultra low voltage. Make sure to make a backup first. And try low before ultra low. Individual devices can be picky about a lower voltage and can go into a bootloop if it can't run on a lower voltage. Droid Overclock has profiles like SetCPU.

After calibrating, draining and recharging and wiping stats a thousand times, this is what I get:

2 hours of screen time there, that seems about normal to me. I'm lucky if I squeeze out 3 hours of screen time throughout the day.

It depends entirely on what you are doing. 2 hours of screen time (even in ideal conditions) will most likely get through half of your battery.
What screen brightness settings do you use?
What were you doing with the "screen on"? (i.e. gaming, video etc).
What kernel do you use? Try the Faux 1.0 Ghz kernel (if not already) and consider undervolting.
I imagine with the combo of Faux's stock kernel, undervolting and perhaps reducing screen brightness will see 5ish hours of screen time.
It was on around 85% brightness due to being under direct sunlight.
My kernel is faux's 1.45 for CM
Over 80% of the time the clock was around 200, 400MHZ as stated by SetCPU, and both those clocks are undervolted by 50.
I was browsing the whole time.

Wow no wonder. Roaming for 2 hours with brightness nearly on full will definitely drain your battery.v Plus the 1.45 Ghz kernel overclocks the RAM and GPU also. You might want to get an anti glare screen-protector and flash the 1.3 Ghz kernel and use wifi.
I'm on the nightlie 18

Umm... wifi wasn't an option back there, and I don't use screen protectors. BUT I didn't know that bit of fact from faux's kernel, I'll put in the 1.3
BTW, Green power pro does help a ****load on keeping battery alive.
ps: anyway to control RAM and GPU clocks the way we do with SetCPU with the... well... cpu?

Why don't u go to a stable version and see if the battery drain continues there also ? You can always create backups to restore right ..

Welcome to cm7. I'm lucky to get 10 hours light usage with faux 1ghz kernel undervolted with a screen off profile of 216-216mhz.

Have you tried installing better battery stats and CPU spy to see if you have a rogue app? You should be getting significantly better battery life. How is your cell signal?

I don't believe setcpu functions correctly for dual core devices, I remember reading, albeit a while ago, setcpu only effects 1 core, leaving the second untamed.
Please correct me if I'm wrong. Stock cm kernel has plenty of ass behind it, no ones playing bf3 on their handsets....yet...

In all actuality, android isn't optimized for dual core devices either. ICS will be.

Watchdog shows the suspend process and android media process taking up about 30% usage constantly. Signal is strong when I'm at work, constant 4-5 bars H+
Even after a full wipe and clean install of CM7 those same processes throw up alerts immediately, I will get al alert for the suspend process every few mins.
Background data off, no email syncing or anything. I'm lucky to get 3 hours screen on time or pandora streaming. I bought a new Motorola battery about a month ago and I don't use GPS or wifi.
Running stock, aura or homebase and the drain is gone... they aren't any good IMO tho.
For now I'm carrying a spare charger everywhere I go till the nexus prime is released.

I know what you meant though. Just saying
My G2 tends to get worryfyingly warm when im using a bit more cpu intensive tasks. The cpu managed to get to 67°C when playing 3 races in NFS Most Wanted and managed to get 76° when doing Antutu benchmarks twice and it started throttling. And battery temp stayed around 40~45°. Idk, if this is supposed to be normal(please bear in mind my previous phone was HTC Evo 3D, which barely got hot ). When idling, the phone is just a bit warm. I'm running OptimusRs Pro V4.1 Stock kernel. Is this supposed to be normal for quad core phones or should I get it to service?

Oh, and when phone is idle, the cpu is 42°C and battery is 32°

This is normal the g2 is a very powerful phone without a fan eventually phones will have to have small fans and phones may be noisier than today's phones

I know that, but it tends to get hot very fast, a couple of minutes heavy tasking and its already throttling

Is it really normal? I mean after 10 mins of browsing even the screen gets really hot..
see if you can check your kernel's cpu profile settings. could be that it's not allowing the cpu to idle when it should be. alot of times there are various profiles you can set it to 'on demand/powersaver/ect...' and this will change the behavior of the cpu's throttling.
Well now we're in the summer and the phone will naturally get hotter since the only thing that cools it down is the environment. If you're browsing under hot sunlight with 100 percent brightness then yes, it is going to get really hot.

its not normal bro. i have the same issue on all aosp roms and cloudyflex roms. my phone becomes really hot. if you give a shot at cloudystock 2.2, your phone wont heat up at all. try it out and be sure to make a nandroid before. just incase if you change ur mind and want to get back to this rom. i wouldnt recommend it though, anthing above 25*C for the battery is bad for its health since its a lithium battery.while the cpu heating up to 70*C is fine i actually use custom throttling to reduce my phone heating that much, i keep the throttling at 60*C
No it gets hot even at 60 percent brigthness while browsing. NFC, BT, 3G are off, i am using only 2 widgets, The top of the phone gets really hot... my sis has S3 and it never ever gets that hot, so do my old Huawei phone..
I attached picture of synapse below with my current cpu settings and my question is is it good enough for performance and battery saving and can I do it even better?
I have android l with unleashed kernel

only you know as we all use our devices differently. there is no such thing as best setting. since we all use our devices differently, best settings would depend on your usage. thats for performance and for battery.
I would recommend bumping up the screen off frequency one notch because with 500mhz, some music playing applications like tune in radio skip occasionally.
