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
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.

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.
Hey all,
I've been noticing over the past few times I've been playing GTAIII and MC3 that the internal temp of my phone rises drastically, to a point where I can barely hold one side of my phone without having to let go every few seconds because it is so hot. From where the battery is positioned, I assumed it might be the GPU heating up, but other att gsII users said their batteries were heating up.
So,
1) Is anyone else experiencing these problems
2) If you are, has anything happened to your phone
I'm debating whether to trade it in for a new one, because I'm still under warranty.
Welcome to high performance electronics. If you push the CPU/GPU hard it's gonna heat up. It's like a desktop, if you do something CPU/GPU intensive it'll heat up. It's a simple byproduct of inefficiency.
As to batteries heating up, that could just be because they're close to the CPU/GPU. Batteries will warm up under high current draw as well.
Do you have a case on your phone? Those tend to trap heat in as well.

If your phone is overclocked, the processor will be running at the max clock you have set while playing the game, which is higher than what it's supposed to be running at, i.e., the stock clock. Prolonged usage at this higher-than-normal clock will generate excessive heat.

Yeah I don't play GTA3 anymore because of this kind of stuff. It doesn't get to the point where I have to literally move my hands because of the heat though. I simply don't like my phone getting even remotely warm. I'm just really anal about stuff like that. I fear that doing it will shorten the life of the device and I love this phone way too much to let that happen.
I'm sure it's designed to run at these higher temps since mine is completely stock with regards to cpu speed and voltage. If I can't play a game due to this, then I simply pass on the game. Same with my computer but I digress...
Download an app to check the temperature. Yes, ideally cooler the better, but the phone is designed to handle a certain amount of heat.
From what the op is describing, that is definitely too hot. Over time the components life can be shortened. But what you'll see first is your battery life going down, even quit working all together.
Underclock the processor. That can help keep the heat down. Even as low as 500mhz can pay many games. 800mhz should be plenty for most high end games.

I'm not overclocked, but yeah, same thing happens with me when I play MC3. I got scaredish since it got a bit too hot, seemed more hot than it was supposed to be.
download the diagnosis app and set it to check your batt temperature, if that gets above 45c I would be worried and think about underclocking/undervolting.
As long as your phone is cool enough to handle, don't worry. There's a lot more to it, but the electronics can take a lot more than most people credit them for. The battery is the most sensitive to temp, but so long as it's not for terribly long periods of time, you shouldn't even notice any additional degradation over the long run.

I have the Otterbox, which is probably the absolute worst case for heat efficiency

I agree! I baby this phone to every extent and I hate that feeling I get when it gets warm because I just assume the worst. I keep thinking the gpu is going to blow up or some extreme thing like that
What temp ranges are ideal?

Average day to day operating temps are between 30° and 40° celsius.

If anyone's interested, I have pretty much eradicated the heat problem while also boosting battery life and conserving performance. This was done through setCpu: http://forum.xda-developers.com/showthread.php?t=505419
The problem was that apps were just running the processor like crazy on the 1.2 GHz speed setting, and it used a considerable amount of juice that was unnecessary, heating up the battery to a ridiculous amount.
But anyway, here's the profiles/voltage settings I use:
Main Governor: 200 MHz - 1200 MHz on demand
Profiles:
- Charging, 800 max, 200 min, ondemand, priority = 100
- Temp > 44.1 Celsius, 500 max, 200 min, conservative, priority = 100
(this is a conservative temperature, but most place the *dangerous* amount of heat at 50 degrees before battery life starts decreasing, the CPU/GPU components have solder that melts at 70 degrees)
-Screen Off, 500 max, 200 min, conservative, priority = 75
-Battery <25%, 800 max, 200 min, powersave, priority = 75
-In Call, 800 max, 200 min, conservative, priority = 50
Voltages:
(I was able to undervolt by 50-75 mV for each and still remain stable, these are tested btw)
1600 MHz - 1400 mV
1400 MHz - 1225 mV
1200 MHz - 1200 mV
1000 MHz - 1100 mV
800 MHz - 1025 mV
500 MHz - 950 mV
200 MHz - 875 mV
and that's it! It's working great, I don't have the heat issues I used to, now I can play graphically demanding games and the temp doesn't rise past ~42 degrees, pretty solid improvement. I also get 24-28 hours of battery life with 2-2.5 hours of screen on time per day.
No need to worry about this. That's nowaday phones designed to be. Just normal heat.

I agree that's how they're 'supposed' to be. But things mess up. AMD processors are designed to handle heat, but they are still known for getting too hot and damaging the graphics chip. Better safe than sorry.

Agreed. theory and actuality are two incredibly different concepts
I remember there was this long debate about ASUS/NVIDIA and how they took away the 107MHz frequency and how it affected battery life..
For the record, on my CPU Spy I have it at 120 hours with 35% at 370MHz and 0% (56 minutes) at 102MHz with the rest in deep sleep and 405 and up to 1300MHz with great battery life.
In any case, there's a discussion in EVO 3D about CPU that might have some bearing on the frequencies and how it affects battery life and why sometimes the lowest one isn't the best for battery life.
Now, of course we know the variances between all the devices posted on here so while a lot of folks might have been fine, some might not, but that seems to be the case for the Prime. Hence we saw posts from folks saying they were fine with battery when it was at a min of 370MHz while some had worse.
Also, the Prime does use a different CPU than the EVO 3D so that could be taken into account as well
Anyways, good read for those interested

Thanks for the feedback. I do appreciate it, but by the looks of your post, you didn't see my detailed description of why the frequencies are set to what they are now. I was more interested in what people are actually experiencing as far as performance and battery in real world tests and conditions. From your post, the information that I believe is relevant is that you think your phone runs fine at 192Mhz. I'll accept that for what it is (a data point) but I already know from experience that you are in the minority here. As soon as I released v1.1 with the 192Mhz min frequency, I immediately started getting inundated with people complaining that battery life was much worse, and the phone lagged more on occasion. Then when I brought the frequency back up to 384Mhz, the vast majority reported "thank you, battery life is back to phenomenal and lag is gone". Well, that's what got me on my quest to actually find and measure the needed frequencies.
No, neither HTC nor Qualcomm set these devices up to work as well as they actually can. They simply do not have the resources and the time. These things are rushed to market and updates are no better: they are designed to "make the device work". That's about it! So when I actually started testing these things, I found that 192Mhz was far too slow to make this phone work without lag. 384 fixed the problem but when I looked into it further, 486 worked even better, and without extra battery drain. I didn't pull these numbers out of a hat nor did I increase them for bragging rights. They are measured values of what the phone actually needs in order to keep up! I spent many hours testing different states, what frequencies are needed when the CPU wakes up when the screen is off, etc. Simply put, 192 doesn't cut it (not even close) and 384 doesn't quite cut it either. When you crunch the numbers, you find that the phone actually needed 432Mhz while running one core with the screen off and 540Mhz while running dual core with the screen on. Lowering those numbers caused the CPU to jump relentlessly between the min/max numbers and when you look at the time and crunch the numbers, it was always shooting for those figures: 432 with screen off and 540 with screen on!
In other words, if you crank it down to even 384Mhz while the screen is on and IDLING (not even running any games or other apps: what you called "waiting for input"), it'll hop up to 1188 much more frequently and in fact, crunch the numbers for the amount of time it spent at 384 and 1188 and get an average and you'll find that on average, the CPU was using about 540Mhz of power with the screen on and about 432Mhz with the screen off. I will add a disclaimer here that yours may be slightly different (up or down one notch in the time table) from the 432-off/540-on numbers, but I did test a variety of configurations as I said in my description when I released 2.0 and 432/540 minimum frequencies were the good middle ground that worked well under all setups from clean install to heavily loaded down. Part of the need for higher minimum frequencies is because with the screen off, there's an initial "crunch" when the CPU is awakened and that often requires more CPU power than when a longer task is being performed. And with the screen on, it is always doing more than just waiting for input from you! There's a lot more going on in there than you think. Even bumping the min screen-on frequency from 384 to 486Mhz caused a dozen posts saying "Wow, lag is completely gone" and "apps seem to open before I even touch the screen". This is not placebo. This is noticeable and even measurable in benchmarks! No, the phone CANNOT and will not instantly crank up to 1188 Mhz from 192 (or 384). I've proven this many times. It doesn't work that way.
You have to remember that the decision to ramp up to 1188 is made at 192Mhz! It only measures CPU load 20 times per second. And it will never be able to ramp up to 1188 in 1/20 second! The reason is that by the time the service reports a high CPU load (high enough to trip the up-frequency), you've already experienced 1/20 second lag minimum. At that point, it takes at least one more cycle to actually increase CPU frequency at which point you've experienced at least 1/10 second of lag. That is almost always noticeable. To complicate matters, if you look at the code for the daemon, you'll notice that it is a "nice" process which means other high priority system processes can actually "steal" time from the daemon and that can actually greatly increase the amount of time it takes for the daemon to actually raise CPU frequency once it notices the phone is lagging. By that time, you've already noticed additional wait to open an app, a "hiccup" while scrolling, etc. The reality is, your phone can lag at 192Mhz (or 384) for several 1/20 second cycles before the CPU is actually ramped up to the full 1188 and THAT is what causes the lag.
So long story short (I know, too late now) I have to discount all your questioning about whether or not I got the numbers right because your assumptions about the numbers are quite frankly all dead wrong! Your scale of the numbers in your car analogy doesn't fit either. I actually do performance tuning on (among other setups) Hemis. The analogy is more like: set your idle to 192 RPM and see if you can keep it running. If it does, it'll be loping like hell and then when you hit the gas, what happens? It bogs. It's because the system wasn't ready for the load. Set it to 540RPM and see how much better it responds. That's a better analogy here.
So I'm really interested in actual results more than people pulling their own numbers out of a hat and saying "these make more sense to me". A lot of testing went into the CPU tweaks in this ROM and I'm aware of "theories" about how people think 192 might be better or 384 is better. Been there done that. That was the boardroom stage... kinda where HTC and Qualcomm left it. We're already out on the track racing and making adjustments.
Oh, and the frequencies are no more "locked" now than they've ever been. I intentionally set up the init.post_boot.sh so that they can easily be changed. So if you want to run yours at the laggier, less efficient 192Mhz, the choice is yours. Just follow Lrod's instructions above. I was going to post those but he did a fine job.
Edit: I also notice you said at one point "So I don't understand why the decision was made in v2.0 to raise the minimum frequencies to 432mhz for core0 and 540mhz for core1.". CPU0 is never run at a different minimum frequency than CPU1. The numbers for min/max are:
- Screen off: CPU0 = 432/648, CPU1 = offline
- Screen on: CPU0 = 540/1188, CPU1 = 540/1188
And again, these numbers came from actual measurements and number crunching. Didn't matter what you used for minimum frequency: you could set it to 192 and run the phone for a day, and then set it to 384 and run the phone for a day. What you'd find is that regardless of what you picked, the CPU was always "hunting" for about 432Mhz with the screen off and about 540Mhz with the screen on. And with screen on, I mean the screen forced on but the phone doing nothing but idling on the home screen. The CPU was doing nothing but typical background tasks with an occasional email or SMS message coming in and maybe a stray screen scrolling thrown in infrequently.

Hello guys,
I bought this phone about two days after release and was pretty happy with it. It felt like the Snapdragon 810 didn't overheat at all and the performance was far better than on my "old" Z3.
Reason enough for me to try PPSSPP and emulate some good old games. For example MHP3rd ran at 100% speed in every area in-game with no frameskip activated.
But after some time (I'd say 20-30 mins) the cpu throttled a lot. The game speed was only at 50% even though the device didn't feel THAT hot (I've seen/felt hotter ones).
I tried the same thing again with the app "CPU Temp", and it seems like the CPU temperature never exceeded about 58°C. I'm not sure about smartphone CPUs but as far as I know, most chips can take up to 80-90°C until they start throttling. My Z5c runs at 52-58°C perfectly fine, but suddenly starts throttling for some reason.
Is it the CPU governor that tries to save battery life? I'd probably need to root the phone to "fix" this, but there are no roots available yet.
Or is it something else? Is the max. cpu temperature set too low? Could it be the S810 has no real temperature sensor and CPU Temp shows me something completely different?
Thanks in advance!
Greets,
Uftherr
I think that Sony it's throttling the CPU more to be below 58°C than to save battery life.
Try with the latest firmware (released today at PC Companion) it seems to be a little more snappier (maybe its a placebo).
I don't know why because the kernel is from the same date.
I consider that they should let the phone gain 65°C to increase the performance (at heat cost).
