ive been running cm9 for sometime now, but only recently started getting random reboots. Im assuming its because my battery is overheating, as its usually pretty warm every time it happens. I set the clock to 1000, and ive checked 16 bit transparency, and unchecked surface dithering(although im having trouble finding the thread that suggested the performance tweaks.)
today i switched to cm10, but the phone keeps getting warm.
should i set the clock lower? or is there something else im doing wrong?

You arnt doing anything wrong. Its because the kernel used isn't made for ics and jb. Its just something most users will experience until moto drops ics.
cool, thanks. I set the processor to 800 and it seems to be doing a little better. doesnt seem to hurt performance that much at all

There is one thing you might want to do. While this wont help it to actually not overheat in the first place, it will help it to cool down quickly when it does. Assuming youre using setcpu or a similar application that allows for profiles, create a temperature profile that drops the clockspeed down to, say, 456 or 608 when temperature exceeds 50 degrees Celsius. Also, making a profile that makes the processor clock down to 3XX or 456 while the display is off will help it to not flip out and overheat while it's idle.

Hi guys!For the last few days(that I have my Hero rooted that is) I'm using VillainRom 10 as my everyday ROM and have tried some others.Anyway,that's not the point!
Being one of the lucky ones whose Hero can happily overclock to 768 I came to use RaduG's extremekernel and ben39's no-bfs no-whining kernel.With the second,while configuring OverclockWidget I saw that it gives a 848MHz option with auto-detect frequencies.Is it possible?I'm not asking about stable daily use,but even for some minutes for benchmarking?Has anyone achieved it?Without making their phone catch on fire that is!
And secondly,why are we all using linux 2.6.29(for total newbies I mean the kernel) while there is 2.6.32-33-34?Can't a newer kernel be compiled for use with the Hero?Newer kernels would provide native ext4 support and would probably prove to be better overall.
Oh,forgot one more!I am currently running on minimum 176MHz-maximum 749MHz(after I got a couple reboots with 768 I abandoned 19MHz for stability) with screen on and minimum 123MHz-maximum 384MHz with screen off.Should I give it a higher minimum frequency?Sometimes it lags when waking up,the screen turns on but shows nothing but black and turns off again or it turns on and everything is distorted,colors are completely distorted,background is upside down and some other unnormal things,but everything is alright when turning the screen off and back on again.Does it have to do anything with the frequencies I am using?I am running on VillainRom 10.3.
Now I have set the minimums to 160 and 190 MHz to see what happens!
Thanks in advance!
About the high MHz... I have done it with over 800 but don't max it out at 848 or your phone will freeze but anything below works And that screen **** I've also had and it has something to do with the high MHz (don't know why) but it helped me to set the MHz lower when the phone sleeps in SetCPU And at last about the kernel... It runs on the old one on Android 2.1 but in 2.2 it will be upgraded to ....33 or ....32 don't remember which...

Thanks for your reply C0mpu13rFr34k!
I know Eclair is running on the old kernel.I just would like to know if it is possible to compile a newer kernel for it.
As for the frequencies...Are my settings alright?Some too high or too low?The way I see it there is a big gap between maximum and minimum frequencies when screen on which results on the CPU working at low frequencies most of the time,thus sacrificing performance.But it helps with battery life and presumably this and the screen-off underclocking reduce the overall damage caused to the CPU by the overclocking,which is said to reduce the CPU's total lifetime by 50% or more,depending on how much you overclock it.Working at 749 I sometimes get a nice 43 degrees Celsius while charging,but that's only when charging.Average temperatures are 30 for standby and 37 with screen on(average,can be lower or higher).
And one more question.At 800+ how hot does it get?Will it be stable for some minutes to do some basic benchmarking or nah..?
Thanks!

If your phone is stable your settings are just fine even though your phone might have problems waking up if the low freq is under 246MHz (something like that) Also if you want better performance you might want to test some other freqs and then benchmark... Sometimes it makes a BIG difference if your phone is running at 691MHz or 710MHz For me my phone works like **** if it runs at 749MHz but it works like a dream at 729MHz (I think the difference was 0.5-0.8MFLOPS) Im also pretty sure your temp is fine (OC shouldn't make your phone that much hotter since the voltages in all ROMs are adjustet). If you should compile a newer kernel you would first of all need a .32 (.33?) from HTC because of hardware capabilities and im sure there's is A LOT more things devs need to compile such a kernel but i don't know to much about kernels I don't really know that much about 800+ because I only did it once and benchmarked it (MFLOPS was **** and i couldn't get them high at all) actually it slowed down my phone but you should test it. Maybe your very lucky and your phone can take it
Well,I have set it to 653min-749max with screen on and 160min-352max with screen off.Testing only!But it runs like a dream if we don't take into account a small lagging when I turn the screen on and it has to change frequencies!But it's great so far.Will see how battery life goes!By the way,tried 800,806 and 848MHz,but none worked.It didn't crash or something,it just wouldn't change to it and stayed at lower frequencies(low as 246).
Thanks for your time anyway!
And a small question...How bad does overclocking affect the CPU's life?I asked around and was told that the maximum overclock for desktop PCs is 20-25%,depending on the CPU,while needing special cooling systems,and that it can reduce the CPU's life up to 50%.Given that we overclock over 40%,how bad do we damage our CPUs?

I haven't heard to much about that actually but from what I've heard it shouldn't damage the CPU at all because of the voltage adjustments but i find that very hard to believe... Talking from personal experience my phone runs as smooth now as it did when i bought it so my CPU has probably taken minamal- or no damage at all and I got it when it had just come out here in Denmark (Europe) which is about 8+ months i think? So I wouldn't care to much about the lifetime since It's probably like 1-2 years and by that time I don't think people are using the Hero anymore Keep up the good work with optimizing and your welcome
I'm running gingertazz on my eris and have heard a lot about people using setCPU to overclock and their recommendations on how to do so. However, I want to use it to underclock when my screen is off but I have no idea what to set it to. I've heard that it's possible to underclock too much and screw things up so is anyone else underclocking when the screen is off? what settings do you use and have you seen any issues or battery improvements? Thanks!

No, you can't actually screw up your phone by underclocking. The worst is your phone might lag coming out of sleep when you receive a new notification or phone call. I've underclocked all the way down to 19MHz before, although I usually do experience some lag at some times. I would say that the best performance while still underclocking is at 245MHz, although you can experiment yourself and find out if 160 or 128, or even 19 might work fine enough for you.
awesome, I'll have to mess with it and see what works for, thanks for the help!

I totally agree with you. ALTHOUGH, if I may make a suggestion. The smartass setting is very effective at automatically scaling down the CPU for screen off and also allows for pretty descent recovery upon wake up. Honestly, I would just rock smartass until you actually needed to scale up for a certain app or whatever. Most off the times even on my DINC I'll just let smartass have full control. But then again this DINC is pretty powerful and never has problems waking up.

Every once and a while, even very recently, I try Smartass again and I almost always end up having lag more often. I'm sure that's because of our underpowered phones, but....just my opinion.
Send me your Dinc and then I'll try it longer!
root rookie here.. First device I ever rooted, really I'm new to cell phones in general.
I flashed this rom adryn bamf 4.1 (non remix) and its working good and all
But I noticed on the smartass setting, which underclocks, that after about an hour or so of playing a game/tv whatever my batter will be around 42C, it seems very hot compared to around 32C before I put this rom and kernal on
Two questions
Am I doing something wrong or is this normal
And, How hot can a battery get before it becomes something to worry about?
Thanks =P
Yea in the 40's is way high. Remember, heat is inefficiency (wasted energy). After playing a game for an hour you will probably be in the mid 30's C. I would recommend trying a different kernel and wiping devlik cache. Also, see what apps and services are running in the background and increase the length of time between syncs. Also, smartass scaling did great on my incredible but I have found that it is not perfected yet for the tb. I would suggest ondemand unless the dev or OP specifically says that smartass is the way to go. As far as heat and battery I find that adrenylyn's kernels do the best. As far as performance, drod and ziggy's seem to fly. Isoman or whatever seems to also be a favorite but I personally didn't have great results. It is important to not supremely OC or UC. I would simply stray away from UC in general. For a daily driver, I would stay under 1.5 Ghz, and honestly 1.2 seems to work best for me. Hope this helps.
thanks for taking the time to respond
So why no under clocking? I assumed it would help battery life but not so much?
Just set to 1200 for both min/max? Or on demand scaling up to 1200?
I prob had a bunch of apps running in the backround, i'm new to droid.. came from an old feature phone
42C is definately too hot! As the previous poster suggested, try a different kernel. There also could be a remote chance your battery is defective.
I really feel like it is more likely that something I am doing is impacting it
I had the phone stock for a week and no problems (same usage)
Rooted but stock rom for a week and no problems
Put this kernal on (which everyone says is really good) and this rom and it was getting hot.. So far it is good around 38-39 (still too high?) with 1200mhz on demand min 256mhz
I flashed 2 different kernals and both times after less than 45 mins of browsing forums and playing home run baseball my battery gets to 42C. Could this be caused by the rom? I wonder if I damaged my battery or phone at this point
Mine got up to 113 degrees over the weekend. It felt like I was cooking my phone off and getting ready to throw it like I do in black ops.
I realized my phone was trying to search for a 4g signal when there was none. I entered #*#*#4636#*#*# on my dial pad to turn it off. It reduced my battery heat by 5 degrees. I should point out I was out in the field. Aka in the middle of nowhere where.

I'm @ 53.4C right now and it doesn't seem to be charging, lol.

Sorry but to fly off topic what do you do? I'm generally out in the boondocks when I'm on wellsite...

42c isn't anything out of the ordinary, or outside operational parameters for a battery of that type. Not by a long shot, actually. That battery can safely operate at 59c, but the phone won't charge it north of about 47c due to the fact charging will increase the temperature even more.
As for the governors:
The smartass governor operates similarly to the interactive governor, but isn't as aggressive and allows for wake up lag reduction. The governor SHOULD be your main line of controlling clock speed, not your min and max settings. Some might like to argue that point, but that's mainly because they haven't messed around with governor parameters. With and ondemand or interactive governors, and even some smartass governors (Not Ziggy's modified), it's entirely possible to set min as low as 61MHz, and max at 1.65GHz and have the CPU rarely, if ever, reach those speeds. It depends entirely on what you've set the governor parameters to be. I don't know of any app that allows you to modify those because the locations of the parameters aren't always the same name or in the same places so it's best done through a script. The script I uses does routinely reach up to my freq_max, but it does it fairly aggressively, then ramps down just as aggressively. Part of that is the nature of the lagfree governor, part of it is where I've set the thresholds. In any event, governor control via a script is a much better solution than castrating your device.
I was wondering what some SetCPU profile suggestions are for the Atrix? Right now all I have is a screen off profile. It has like 608 max and 216 min.
Ideally I would want to set the min a little lower, but it doesn't seem that I can?? It's also kind of annoying that each value can only be set to certain increments, like it jumps from 608 to 450 something or 760 something the other way.
Any thoughts on some other profiles I would maybe want to set?

That screen off max seems sorta low. You haven't experienced any wake up lag or anything while using that?
out of all honesty i used setCPU for a while and didnt notice any difference other than wake lag on my LWP. The phone is already excellent at managing the processor loads on its own. To me it was Just another app using up my battery. I will def use it once OCing is possible. It didnt really seem to have any benefits IMO. I have great battery life without it and thats with chainfire, sdspeed increase, Titanium, and a few others running unrestricted by my task manager. Once again just my opinion.

nope no lag here
I see, I could probably get away with setting it even lower.
Dirtburgler, yeah that's mostly why I've only set one profile so far because I haven't really noticed a super high need for anything else lol. I did notice that, in spare parts, my runtime greatly exceeded screen on time on average, so I wanted to make sure to limit the CPU while it was off and it actually has worked very well. I'm only about 1-3% higher with runtime now, even with heavy usage!
I'm running subpsyke's CM7 port on my u8160, and have overclocked the CPU to 691mhz using the the smartass governor. The processor runs at 600 by default. Any higher than 691 and it immediately locks and restarts. At this speed it doesn't reset any more often than at default, something this phone did every couple of days even before I flashed the ROM, and it never locks up.
So my question is: at what battery temperature should I start getting worried? During browsing it gets up to around 25 to 28C, but when plugged in and being used I've seen it at 36C occasionally. I have a feeling that's pretty high.
Watchtower isn't showing me any processes eating up runtime erroneously either.
I'd really like to keep the higher speed, it's just enough to view higher quality video on this toy.
EDIT: The battery temp sensor is the only thermometer on board, I think. AndroSensor picks up another one but its forever 'waiting for event' so I don't think it's really there.
