Did I FRY my CPU??

First of all im not putting down anyone and there custom roms. As I am an avid flasher of them and there great features..
However.. Ive noticed with every rom I flash, my battery life SUCKS. I know kernels are suppose to have battery saver mods, but never seem to work for my phone. The only way I seem to get great battery life is if I odin back to stock. Its seems to last forever on stock.
On stock.. I would average around 10% drain every two hours of moderate use.. mainly texting..
On Custom roms I average 10 to 15 % drain every hour with same moderate use..
My question is, Could Overclocking have caused this problem??

Quite possibly... And unfortunately, you have to test different Kernels with your ROM to see what works best, or just ask the Dev which Kernel they used when developing the ROM... That's a good way to get the best battery life because after all, that's the Kernel the Dev based the ROM off of. Another option is to check out Marcusants post on setting up your Kernel for your ROM, and I apologize if you've already tried that... I'm just trying to list options... I've had problems with different kernels on different ROMS... Well at least until Rodderik started making his Kernels with Viper ROMS... Then it started working perfect lol. How are you running your clocking? Conservative? Performance? Also, are you using SetCPU with an OC/UV kernel and the Voltage Control app? If you use the two together, it could cause a lot of issues, you'd have to choose one or the other.
On the other hand, I could be 100% wrong and it could be just your flux capacitor... You know how touchy those things are. Try chucking your phone over 88 MPH and see how that works. The next step is VERY important though... Whatever you do, don't forget to put your phone in airplane mode before you throw it in the air or it'll just fall right back down after a couple feet... Keep it in the air I always say.

Im hoping once I hit 88MPH it will go back in time to when my phone actually worked. haha
I usually just use the Kernel that comes with the rom..
However I have used Set CPU and Voltage control together once. I messed around with the setting between performance and conservative.

Orion, first off. If u remember how "beepers" worked back in the day, if u ever had one, that's how text messaging works. It triggers a small ping when being sent or receiving message. So text messages really hardly use power. As far as ur battery is concerned, try this method if u like, just to see what kind of results u get. Charge battery completely with phone on first and then off. Then boot into cwm and wipe ur battery stats. Then drain ur battery completely without charging it. Then completely charge it up, and then see how ur battery does.

One more thing. Anytime u change rom or kernel, update ur prl and profile, then reboot ur phone..it does make a difference doint this.

True, just don't wipe your battery stats too much, it could end up doing more harm than good. But good call, I overlooked that cuz I was being a smart ass lol... Please don't throw your phone, that's never a good idea haha.

Were you overclocking when your battery life sucked? What uses more gas, riding at 55MPH or 90MPH? What was your battery life like on custom ROMs with stock frequencies?

Battery was ok when I overclocked.. went down hill after that. Except whenever im on stock EI22 Gingerbread and it runs all day.
On custom roms with stock frequencies I would still see a significant drain.

I don't think you fried it if it's still running fine on stock. I'd be more likely to think you're overclocking with an aggressive governor that is making your cpu stay at higher frequencies.

I havent been doing any OC or UV in months now and still have the problems on custom roms. Perhaps I got the phone that doesnt like to be modded.. Damn Sprint ha

also screen brightness has a HUGE effect on battery life. also do you do games and such? Those can be very draining as well. I am on a viper rom going on 14hrs and still at 78%. but i mostly text with my phone. about 15,000 a month to be exact. and use f.b. and xda pretty heavily. and different kernels can make the difference between 6 hours and 20.

i will say that my phone is particular on what rom i do run no matter what kernel i use

I just mainly text and surf the web occasionally. Funny part though the only game I play rarely is Deer Hunter Challenge which is a pretty high def large file game and when i play that my battery doesnt seem to drain. Right now Ive gone down 10% over the last hour just sending about 15 texts. And I have my display set to auto brightness

It's real simple...overclocking equals faster cpu AND faster battery drain. Do not overclock or do not complain about battery...one or the other.

Horrible Battery Life for me

My phone has TERRIBLE battery life. In about one hour (on stanby with wifi or data on) my phone loses 10% battery without use.. Which is a 10 hour battery on stanby. I can BARELY make it through one day without my phone dying either. By the time i get home from school, my phone is down from 100% to 65-70% with VERY minimal usage. Then by 9:30pm my battery is down to 20% with moderate usage on wifi. I am running Beastmod 4.2 REMASTERED with whatever Kernal comes with it.. I have tried Juggernaut, Beastmod, Beastmod Remastered, Stock, unrooted, domination with no luck. Ive tried underclocking, over clocking, changing settings, brightness, different launchers and so forth. Still, i have no luck. Yes, i have calibrated my battery, and this is my second phone from T-Mobile (and 3rd battery) that has a short battery life. Can someone PLEASE help me with this. Thanks!
EDIT: Just typing this message i have lost 3% of my battery on wifi...

I really dont know what the general view on this is....but if you are flashing a lot you wont know the difference. You need to get through atleast a few full cycles to figure out if something has decent battery life. No ones phone is going to put out the same results. I have had a lot of bad results with ROMs people claim to be the best. Just try a rom + kernal combo, give it a week, see if things start improving, else flash something new the next weekend. Do proper wipes, restart your phone when its charged at 100% and go from there.

You leave GPS on? GPS is a drain even if you're not actively using it. Also try charging the phone to 100%, then drain the battery completely, then charge it back up to 100% with the phone off. I've found that usually greatly improves battery life.

Do a full wipe and flash macnut r1. I had similar problem as you until i flashed this rom, i think his kernel has the best batt life of them all and most stable for me. Worth a try

Check Battery info. Is your phone awake even when the screen is off?

I leave it on lionheart governer with max 1,512 and min 192 and it works very well for me

Try this wipe your rom clean and dont install any apps just your emails and try it for a whole day maybe an app is eating your battery in the background.

There should be a "Screen on" section and an "Awake" section. The two should be pretty similar. If you see a lot of Awake time even though the screen isn't on, it means you have a wakelock.

[Q] Why is my battery so bad on ICS? Can I downgrade to GB?

I'll try to make this as simple as possible.
On VeNuM's GB ROM, I was getting at least a day on my battery, it was fantastic. Modem was EL29 (I believe, possibly 26 though). I could use the phone a lot and it still got good battery life. With the verizon PRL, forcing roaming 24/7, I could almost get two days on it since there was less time it was "Searching for service"
Now on ICS (have done stock, calk, venum), I have been getting dreadful battery life. Take it off the charger at 9 and by 3, after using the phone during my hour commute, it's dead. The place that I work has pretty bad service for sprint, barely hovers at 1 bar if I even have service at all. One thing I have also noticed is that even on stock (and stock PRL), my phone does not seem to roam, at all.
Here was day one on FE22 stock: https://www.dropbox.com/s/mwjr5j3nd5vgody/2012-06-06 15.36.08.png
Day one calk FE22: https://www.dropbox.com/s/0lroppsxl1bzbup/2012-06-07 18.14.04.png
Battery 2nd: https://www.dropbox.com/s/pttz5fla4us8evk/2012-06-07 18.14.08.png
You'll notice that there are a few bumps at the end. I did have it charging on the comp for a little bit before I left work, those are the two spikes. HOWEVER, it also rose on its own. It went down to 5% and then went UP to 6%, staying there for a bit and then going down.
There seems to be something funky going on, but I just dont know what. I'm currently testing what the difference is with the verizon PRL, I have that on there now.
Are there some battery logs I can post to perhaps decode this puzzle?
-----------------------------
Second question. How do I go about downgrading from ICS to GB?
Thanks a lot.

You should try calibrating your battery and wiping the battery stats at 100%. That would speed up the settling in.
I suggest using sfhubs Odin one click package to revert back to GB.

Something is keeping your phone awake. Download badass battery monitor and check whats using up your battery.!

I'll do that right now. I just took it off the charger an hour ago and it's down to 85, just sitting in my pocket. I'll let it charge back up to 100 and then clear battery stats. I'll use it today and if it's still bad, revert to GB.
You look at the pics? They're depressing.

i definitely think you have apps causing wakelocks. try disabling dropbox, facebook and other random programs that sync, same goes for other stuff u may have polling for updates. with exchange syncing every 15 minutes i think i get better battery life vs push. Kobridge tweaks helped a ton.
white signal bars- cm9, the other is stock fe22 w/kobridge
id defintely search the forums for better battery stats (the dev made it available for free to xda users) or badass battery monitor in the market (also free)

I'm on Kobridge aggressive! I tried moderate as well.
Can anyone else confirm the first reply as to how to downgrade to GB? A direct link would be nice as well.

Battery life is not as good on ics and I too had the same the same problem. System monitor wouldn't pick up any program eating up CPU. Took me for a few day to realize I had a bad install. I had to Odin back to el26 and re install. That seemed to fix my problems. Which is my understanding is the procedure one is supposed to take when flashing from ics. So regardless your flashing back GB everytime you flash roms. but might want to give ics another shot when you flash correctly.

Must say it took me several weeks to find the right combination of parts to get my battery right.
I found that several of the newer modems were overheating my phone and draining my battery in a couple hours. Right now I'm running wicked ff02 rom, agats ff02 kernel and fe21 modem. Battery never get above 90 degrees; and yesterday I got an 8 hour day of work with heavy use (no mid day charge).
Edit: I tried venums boa rom, with very good results too. He included badass battery monitor, which seems to be one of the best of the bunch.

I did downgrade back to GB, running Blazer's EL29 rom with verizon PRL right now and from what I saw it was decent, even through the first battery cycle with the ROM. I'll see how it runs this weekend.
If I want to go back to ICS, can I flash straight from EL29 or should I flash the EL26 kernel first and then upgrade?

ICS Battery life
I have been running "Wicked Sensations" now for 4 days, with the FF09 Modem. I also added the FF11 Kobridge Tweaks to the mix using the aggressive zip. I have been getting roughly 15 to 18 hours out of my battery. I keep my screen about 15% on the slider for brightness. I am heavy user and this seems to be the best combination for my SII. I came from Calkulin's 3.0 GB... If you decide to go back to ICS, this combination. Good luck.

Battery life poor except for stock

I give up.every ROM I run just doesn't have the battery life expected. Am I expecting to much? Not even Cauks or blazer el29 doesn't give the battery life as stock.don't get me wrong they are all great roms but at least for my device not battery friendly. I'll post some battery stats from BBS if anybody has some free time to see what's going on. I'm on Cauks el29 now.I format everything before flashing and I use cauks format all many times. I'm on the verge of staying on stock roll my eyes.

Well when is the last time you used stock? And if it's been quite a while...consider having your battery checked out. Anyway, I'll continue as if your battery is fine from here on out. Basically, anything but stock tends to have a modified kernel. Even with all the battery tweaks, etc out there, there's a chance that the kernel itself might not play well with your phone. I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?

I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

Agree, everyone have different experiences, I haven't try that ROM yet, I will test it out later. Have a nice day/night sir.

Sadly I have to agree with OP.
And the previous screenshots at 59% with 1hr, 36 screen on is exactly the issue.
Hard to compare your battery stats with mine since screen on time for my phone will be 4+ hours.
Since there are no standardized testing anyone can do with any rom, any speculation on which rom has better battery life or doesn't is just pure bogus seat of the pants gut feelings.
If there were a standard test that ran like. 5 minutes of mail with 20 mails received, 10 minutes download, 30 mins of playing the exact same video, 13 music tracks of the exact same song all with screen, vibration, brightness, etc all at the exact same level, you could get a real test, but, alas, nobody has a standardized test.
For MY usage, stock clocks in at the same as or better than just about any other rom I've tried, including all the various super scripts out there.
I guess I just overuse my phone!

How did you get this type of battery life? please share the steps on how you rooted your phone up to the operation.
thanks man.

Things drain battery. This is my test off wifi for the most part using the phone as a phone with average use. Didn't even log in to Google on this one. Just proof that intensive applications, google services, and anything else added after a "factory flash" can manipulate battery life significantly.
Oh, and check out drain when I'm in less than ideal coverage. Noticeable difference. One huge factor to consider when diagnosing battery life.

It really depends on what you're doing with the phone. Obviously having brightness up playing heavy games with Wimax on will kill battery faster than someone on low brightness reading an ebook with wifi on. That said, i agree that I've had better battery life stock than almost all ics roms.

Truth to the last word.. I hate battery life threads too many variables.. I love the part about " using the phone as a phone " you crack me up B..:laugh:

[Q] help with battery saving kernel settings

Hello. Not sure if this is the correct section or not. But here goes.
I was running rootbox 4.2.2 and kt747 kernel. Along with baconatorx something script to apply settings to second core. I was getting roughly 3 to 4 hours screen on time. Great!
Recently I installed slimbean 4.3.1 after hearing so many people say it has the best battery life. With the according 4.3 kt747 kernel. I applied the same tweaks etc but at best I can get 2 hours of screen on time. Maybe there is a new script I'm unaware of.
I use my phone frequently but not heavily. Just phone calls SMS and abit of chrome. Can anyone give me some advice. Or someone with some working settings with the combo I have? Or should I just go back to what I had?
Any help would be great.

Thanks. Just tried out your settings on my setup with the badass gov and slightly more under clock. And that's all you done?
I'm on 34% and only 1 hour 25 min screen on time.
And its 3rd on the list in battery stats.
I might be wrong but should cell stand by and phone idle be on top for battery usage? This is driving me nuts I have to carry my damn charger during the day.
I will report back after a few cycles.

What I am putting down below are purely from my view and my observations over the past few years.
There could be multiple issues:
1. Your battery might be getting old. On 2.8 I set the record at a whopping 7 hours display time (battery less than 6 months old). On the same ROM I was getting barely 2-3 hours (battery near to or over 18 months old) a few days before I flashed 4.1. So when I got 3h45m today, I consider that a pretty good battery.
2. You signal levels at home, the areas you roam, and at your work/school. These too kill more. Example, battery discharges slowly (when idle) at home compared to when I am at work cos of low signal levels at my work place.
3. Maybe there are too many background apps.
Example: Kik, Facebook, Google Plus. These are known battery hogs. You either uninstall these or freeze them when not needed. Your battery will thank you.
4. Kernels don't suit every phone. What works for me might not work for you. Example: Kernel of 2.8 people loved. But for me it drained battery crazy. I used Kernel C of prior version of ROM. Try out multiple, but give atleast 3 days to validate each.
5. Most importantly, do no UC too much. A phone spending 10 seconds at 1000 MHz could need 30 seconds at 800 MHz to get the same task done, and this could actually drain your battery more. For me, after using multiple phones on multiple ROMs, I found speeds between 800-1200 quite satisfactory. This is the reason my clock is normally set to 1000 as max.
6. I barely UV. UVing a little aggressively might seem to extend battery a little, but in the process it kills the phone processors and other parts. This is because they are getting strained working with lower currents than recommended. Also it is a normal practice to actually send a little more than needed currents to phone processor to avoid phone being shut off.
Our devs here who make kernels already reduce the voltage to sustainable levels to improvise on the kernel. This is also one reason why I don't bother about UVing any more.
Sorry about being lengthy and boring :victory:

Lengthy but not boring at all. ill try to add some more info on my phone and its setup.
1. my phone is less then 6 months old. 2.8 what? kernel version? 7 hours id poop a brick. lol
2. my signal strengths haven't changed at home or at work. I work outside lol however at home i do have a mountain behind me. literally a cliff side and i always got half signal since i got the phone.
3. i got the background stuff kicked. got greenify running and i have it hibernating just about everything it will let me.
4. ok this brings me back to what i was thinking originally. maybe i should just go back to what i had with rootbox 4.2.2 + kt747 kernel and scripts.... was trying to avoid this lol. 4.3 must just not jive with my phone.
5. i do have my voltages under volted 50 across the board. i have had the odd random reboot. my clocks were always either 1.2 or 1.0 ghz. never did oc or uc too much.
i will set my voltages back to stock after a few cycles.
also i run fs trim. supposed to stop lag or something. i been running it on all my devices so i figured i may as well follow suit with my s3. i also renamed mpdesion.
my standby time is still good. ill get 2 days on weekends when im not using phone much. but screen time is still less then 2 hours.
i just finished the first full charge with what u recommended. so lets see. heading out for 10 hours here soon. lets see how it does!

My bad! All my references to ROM or kernel versions pertains to Intergalatic ROM and its kernels. Sorry, I should've mentioned that.

Thanks for your time. I've tried your settings for a few cycles. 3+ hours battery. And 2 days total. Not bad!
I have a question. I'm reading on that intergalactic ROM, and it says about certain bootloaders. One is non reverse able or something. I've read on it and I can't figure out what one to use. My phone is on telus if that means anything.

Thanks man. I downloaded the mj2 boot loader and mjb modem package. Do I flash this prior to the ROM? And say I choose to go back to slimbean, do I have to do anything to reverse this?
Sorry I just never had to do this on my nexus 7 or ace Android devices . I just wanna make sure I cover all bases. I kinda miss a two based ROM and after hearing your success with battery on it. Its obvisouly the ROM and kernel combo for me. Games I could care less about, I use my phone for texting Facebook and browser. And I go long periods without access to charger.
Thank you so much for all your assistance.

Yes. Following the same sequence of steps mentioned there. I too did the same.
And rest assured, once you are on this, I don't see a reason you'd even want to go back
Until this release neither we had to do all this boot loader thingy. But with the latest release Samsung did something that created all this mess.

1. Try updating your TWRP.
2. Try downloading the zip again, and verify the zip.

Thanks. This wasn't my issue. I needed the i747m boot loader mk5. Intergalactic thread op directed me to it in the s3rx thread.
About to install here soon, backing up and doing a nandroid just incase.. Im going to go With kt kernel and your simple adjustments.
I see u were using 1 15 kernel. I got 1 18. Shouldn't make a difference?
What are u getting now for screen time?

That was very dangerous. Sorry, I too should've asked. Had it gone through, you could've ended up bricking your phone. Whew! Missed by a whisker!
And I flashed 1.15. I am not sure of 1.18 'cos I haven't installed it. But newer version should be better.

Hey!
So I ended up leaving that tw ROM for now. I made a nandroid so I will try it again.
But I'm here to report my new setup and battery stats.
I'm running slimkat rc2 with the latest ktoonsez kernel.
I'm using your settings in ktweaker but I ended up back on koonservative gov and enabled hotplugging.

We are all so used to getting good battery, it hardly matters anymore, unless someone posted a hard-to-believe 10 hours on stock battery.
