Hello everyone.
I am looking for a relative best rom and kernel combination for daily use which focus on heating and battery life.
I’ve tried AOKP38 with franco185 and did't change the setting of CPU model. The temperature raised to almost 50 degree. I only open the instrgram and twitter for 10min.
I also tried the slim4.0. The heating is much better than B38 with franco. But battery life seems not good.
Wound you mind recommending the best rom and kernel combination you have ever used?
Thanks! Sorry for my bad English.
I too will like to know. I will be watching this thread very closely.
After browsing through many threads where talk regarding heating issues take place, I'd say underclocking are undervolting are your best bet.
If you don't play any 3D games or do anything that requires some real juice from your CPU, I'd say you'd be fine with underclocking to like 1036 MHz and maybe do some slight undervolting.
If you only want do to the underclocking part, and if you got heating issues with Franco, then try Morfic's trinity kernel.

185 seems to have quite a few problems (see Franco's thread). I jumped ship onto the 181 kernel - wireless tethering (encrypted) works, the GPU is fast enough, and it doesn't seem to overheat. I don't use the kernel for benchmarking (although..... ) but rather, to improve the GPU performance.
And I'm on stock ICS, not AOKP.

I only pay the Temple run sometimes. Does this game require a high CPU?
And how about the battery life on your nexus? The screen on time? 2H?

I changed the franco nightly to milestone4 and now heating is gone, even play Modern Combat 3 us no problem. AOKP with milestone 4 is best for me bro! ;-)

I've been underclocked to 1036MHz for a while now and I've never had and problems running any games. NOVA 3 and similar games runs great. The only issues I've had are when I get a call or SMS. Then my phone starts to lag, but eventually picks itself back up.
Every device is different. What works great for someone probably won't work great for you. You have to try them all to see what suites your phone the best.
There are already many threads discussing this, please use an already established thread instead of creating a new one.

I have no experience overclocking a mobile device, so I have no knowledge about what is standard/good/bad/safe/unsafe. Basically I want to overclock my Gnex but I don't want to shorten its lifespan. What's a safe amount to overclock to that won't be bad in the long run for my Gnex? (Running Franco M4)

I've personally never found a reason to overclock this phone at all, and that's usually the best for lifetime preservation.
As far as I know recommended maximum speed of CPU is 1,5ghz, so theoretically it is safe to overclock it to this amount. But I don't know if the build of GN for example do not make the CPU heat more what can cause less life time in such speed.

Q- What's a good gym/pool nearby?
A- In my experience, best to not hit the gym or swim....
Q- Getting a new car, any auggestions?
A- Best not to get one. Take the bus...
I'm running francos latest kernel. I just picked the highest OC on the list (1344mhz). I think the non-stable goes higher.

Non stable goes to 1500mhz.
About the "to overclock or not to overclock" discussion, i'm leaning towards not needed YET. The phone still packs a punch when it comes to gaming and such IMO.
OP says he is noob with these things aswell, so it might be wise to wait a little and get some android experience before jumping on the OC train.
That beeing said. Every cpu is different so one cpu can be clocked to 1500mhz while a different one will fail when beeing clocked to 1300. You just have to try different clock speeds and check if it is stable or not. The cpu have built in throtteling when temperature limits are reached.

Well i have a phone, and in that forum members says that Overclock the cpu shorts the motherboard life, is that true? and for those who are using Overclock, do u really feel something diferent with the performance of the tablet? or do u see something wrong with Overclock? like random reeboots or makes the tablet hot? Im thinking in OC or not my tab, so i wanna see the experience from other members, thx in advance. :good:

I cover this in the guide I wrote in general (which has been pushed down quite a ways) but anyways here goes another version.
Overclocking varies from device to device, even of the same model. Variances in tolerance is on a per chip basis, as long as they pass within a certain range they are sent out for production in devices. Overclocking in general is within means of the chip's abilities, if it isn't, you'll know it. Generally speaking, 1.4 GHz is perfectly fine on our devices. 1.5 GHz is also usually ok, but is the upper end of what the Tegra2 can usually tolerate. Few an go past 1.58 GHz, my old G2x's tegra2 could hit 1.7 GHz,but that's well beyond "normal" range.
Overclocking a device is the same as overclocking a PC, you need to be careful with it. Don't just ramp it to 65% overclock and expect it to run fine. Every chip is different. Do it in steps, and test each step before moving on. Test it in normal usage, test it in heavy usage, gaming, etc.
An overclocked device will certainly run hotter then normal, it's running faster, drawing more power, and that creates a hotter running core, no way around it. Keeping in mind there is no airflow in these things, that makes the biggest enemy to CPUs even more dangerous.Does it run so hot that it can shorten component life? Sure it can. Will you still have the device when it happens? I doubt it. Likely, we'll be on Tegra5 before it even begins to show signs of stress.
One of the nice things, though, is our CPUs range so much in speed according to load that just because your Max is 1.5 GHz, it doesn't always run there. Most times, it won't even be in the overclocked speeds. Does it run faster? Sure does. Benchmarks will raise nicely, and games that maybe got choppy before will smooth out, movies that couldn't play well will be fluid, the heavens will align, mankind will discover world peace and I'll win the lottery.
All that being said, I don't usually overclock, in fact I tend to underclock a little to 800MHz. Its usually sufficient to do normal tablet stuff, and I adjust the speed according to what I require. If my movie is lagging, I'll bump it up until it smooths out. Same for a game if it needs it.
In the end, its all personal choice, really. Just because you CAN overclock, doesn't mean you NEED to. IMO a well tuned governor will give as good a result as overclocking in normal usage, and a good I/O Scheduler will also help alot, without adding anymore heat or stress to your device.
TL;DNR:
Overclocking is fun. It causes more heat. It likely won't explode within the time you own it. Or your children. Your battery will suck.
thanks pio for the answer, thats what i needed to read, cuz usually when u talk about OC its like "yeah dude, OC its "tha greeeeeat doi it dude" or something like "dont do it!!! u will decrease your tablet life" and yes, i know that devices are way to diferent even if they are the same model, and also im agree with u, governors and I/O works better than OC but we dont have many for our device, i miss the smartass v2 governor,or the brazzilianwax too, but well, hope someone can port it for us someday.
What are your guys' opinions on the performance of these two kernels? From what I've gathered it seems like KToon's kernel is meant for overclocking, but then what would one use task's for?
Task's recent update to his kernel makes me want to try it because I've been using KToon's kernel with the ktoonservative governer and row scheduler UV'ed a little bit but unlocked to 2.1GHz and have been having some pretty bad battery life in mu opinion, do you think switching to task's kernel would be better on the battery?
Well what do you guys think?
Fun Fact for the day. Versus threads get shut down in no time here on XDA.
P.S- Why wouldn't you just try it first before making a thread about it? Kernels take about 3 seconds to flash. Also. No one can tell you that you will get better battery life on one or the other considering all of the variables. We are all in different locations, use different apps, have different settings, and we all use our devices differently. You need to try them both out and see which one works better for YOUR device.
Man why are ya giving me a hard time? You kicked me out of your thread, which I understood and respect, but then you come here and tell me the same thing you told me before and that my thread's gonna go to the bin in no time.
I'm just trying to find out what the DIFFERENCES between the kernels are, because it isn't very clear in reading the descriptions/OP's,
They wouldn't co-exist if they were exactly the same.
I'm not too interested in tweaking the hell out of my device nor do I care too much about overclocking...I just want a lot of screen time and the ability to play games and SMS with little lag.
I have tried out both kernels and didn't really notice much difference because I didn't really know what to look for.
Like, okay or example, it seems to me that your kernel is less for tweaking and isn't for overclocking (max 1.6GHz or something?) while KToons can go to 2.1.

I'm not giving you are hard time. I'm just telling you the facts here. If you're not into tweaking and messing with things then this is simple and really shouldn't make a difference to you which one you use other than battery life, less lag, ect... Which no one can tell you one is better than the other for. Flash one and don't touch the settings for it and use it how you normally would for a day or two. Then do the same for the other kernel. See which one gets you the best results. Its the only way to find out. Not quite sure why you're refusing to take my advice here. Its pretty straight forward.
There's kernel source in both threads that explain in DETAIL all the DIFFERENCES between the two. It literally only takes seconds to flash and see for yourself. This shouldn't be a big deal at all.
I think they re two of the same.Task just doesnt want KT to know he borrowed his kernel...lol jk. But seriously,they're pretty similar.KT seems better on the performance end but I never got the exceptional battery stats that ppl keep posting,IdK it may be something on my end. On the other hand, task's seemed better on my battery as I could not noticeably see my battery drain during use as I did on Kt's. Furthermore my phone does get hot really fast on task kernel,I'm guessing its cuz we use performance control and can't really play in the voltages as much.

I have flashed both kernels. And I don't mean that I am not planning on doing ANY tweaking whatsoever, I just don't mean like messing with voltages adding or subtracting 25 at a time until my CPU crashes so I can find the under/overclock limit...that's the kind of tweaking I have no interest in trying. I'm not gonna look through he sources of both kernels, come on dude you know I'm not a dev and that level of detail is un-necessary.
Your kernel being capped at 1.6GHz probably is better on battery but I also have a sixaxis controller and like to game, does it affect 3D performance at all?

This is the kind of posts I'm looking for in this thread. Do you personally find task's kernel's performance to be any worse than KT's? Cause you said bettery life seemed better.
Also, are the same governers and I/O schedules available between both kernels? The only settings I'm used to using is ktoonservative and row, I wouldn't really know what to do in performance control to emulate what I've done in KTweaker.

He cannot answer this question honestly. He doesn't have your device. You're not understanding. He can have the best battery life possible on my kernel but if you use it, you could have the worst battery life possible. IT'S DEVICE DEPENDENT. Will you please just do yourself a favor and take 3 seconds, flash the kernel, and see. You say you've tried them both, but you are also asking about playing games and what not with them? You would know if you had tried them dude. Same goes for the governors & schedulers. You would also know that if you had actually tried them both. I need to ask you this. Why won't you just try them and see for yourself. Are you really the type of person to flash what people tell you to your expensive device?
Look dude. I'm only trying to help you here. I'm not quite sure why you wouldn't just take my advice here. I have quite a bit of experience with this stuff and I'm trying to help you get the best experience possible. But it seems as though you think that personal opinions of others are whats best for your device when in all reality they are not. Real life testing is what will prove to be best for your device. Trust me.

What You won't have on underwear kernel vs kt747: ktoonservative gov, vibration strength control, screen off max freq control, screen off gov control, fast charge, MHz range from 96 to 2106, undervolting capabilities and adjustments to governors and schedulers.
If you don't want to undervolt or tweak anything, I recommend you use underwear kernel. It is stable fast and oc to 1674mhz is alright for any gaming and it doesn't affect 3d performance.
If you wanna use ktoonservative governor then you will have no choice but to use kt747.
But anyway, what you really need is to try both and familiarize yourself with their features.

Thanks everybody for their input, if anyone else has anything to say then please go for it!
Wiping cache + dalvik and flashing underwear kernel then fixing permissions and rebooting and gonna take a look around performance control to see whats up.

Here is some info on Governor and I/O schedulers. Obviously it isn't going to include Ktoonservative or ROW but you get the idea.
Hi everybody,

Also, If somebody is going to work on this challenge.

A57 cluster, probably yes. I'm also working on a kernel, but I intensely dislike Overclocking because it isn't all that useful. The key to performance is with optimisation, not with raw power. So I'm most likely not going to include it, sorry.
What about underclocking and/or undervolting?
I think performance is good enough as it is, but would like to get better battery life.
I would like to be able to undervolt in order to relieve the bugging high temp warning. This phone rarely uses max performance. So, overclocking is not really a priority. Maybe a custom hotplug.
Crappy cpu. No point messing with it.

Hotplugging has been dropped not long ago. You'd basically need to reinvent it. Plus it costs more power than it would save
And what about undervolting to prevent excessive heat, @mythos234?
yea i guess undervolting is the only benefit here coz 2 ghz wont be hard to achieve but getting that overheating msg sooner aint worth it...
next thing u know is accessory back plates with mini fans to keep the phone cool...
seriously tho what good is the extra power for ? the phone is already fast with the correct setup (not that i saw any lag when it was stock)
anyone knows how to see the cpu binning in this phone?

A number of people have gotten over-temperature messages, sometimes with the phones even shutting down.
This has been reported with using navigation, I believe, and I know people have reported it when shooting video. High screen brightness is likely a contributor. But there are examples of the phones running too warm.
Personally, I'd be more interested in cooler running, and longer battery life, rather than increased peak performance. So underclocking, if anything.
Well, the overclocking is not necessary, but is an opportunity to know the limits of the chipset. Moreover, with it we could know if we can make undervolting to our phones and make it more battery efficient with an underclocking kernel, when we need it.

Happens to me too when gaming. The problem I observe is that Indeed, it is not excessive heat. But LG thinks otherwise.
You can actually underclock using Kernel Auditor and disable cores. Unless you meant Undervolting.

Currently using Kernel Adiutor to disable both A57 cores and the phone screen does not heat up like before... Battery life has improved from what i saw yersterday. Continuing testing today. Only problem i have is the damn phone will enable one of the A57 cores after a while which i dont like. I need my settings to stick.
Any Kernel Dev know which files are causing this? Tab 3 had something like this but a couple of files changed solved the non sticking settings on cpu.
Overclocking/underclocking sure but just disabling cores would work for most.

I haven't had any popups or heat related reboots, so I was wondering what the matter is here.
On every phone I see complaints over heat so I wondered if something is to it here or if it's the usual. And if there are overheating warnings and shutdowns, then there might be indeed something in the bush.
Try charging your phone in the car whilst using google maps to get to an important meeting, and then take a call just for good measure............and boom, there you have your own little meltdown.

That happens on every phone I ever had though. It's advised to not use a device while charging at all, so if you stress it to 120% while charging, of course it heats up..
@mythos234 is a pleasure to have you here (speaking as xiaomi mi2s owner too xD)
What Temps do you reach using cpu intensive apps?
