Stock vs Overclocked

Is it worth rooting my phone and overclocking it?
Is overclocking it really noticable in performance to say approx 1.5GHz? And is it going to kill battery? Thanks

Yes and Yes to both of your questions. There is a noticeable diffrence in performance when overclocking. But it will obviously use more battery

cant say ive noticed 1.5ghz killing my battery.. might be used a bit faster.. but u can easily offset this by lowering your clockspeed and voltage for your sleep state in addition to minimising the required voltage that 1.5ghz requires, id say my battery life is probably better overall, and i run 1.5ghz 24/7.
of course your mileage may vary depending on usage and various settings.

How hard is it to overclock it? My phone is rooted but I have no experience with overclocking.
I'm guessing it wouldn't be a wise idea?

Yeah this seems a little over my head.. thinking of buying another Xperia Play just to mod the crap out of.
Dont really wanna mess with the overlocking now I think about it incase I fry the chips and kill the phone.

At 1.4 and 1.5ghz its quite safe.
To chill out the battery put some screen off underclocking like at Real low with but not the least
1. 4 ghz scaling interactiveX I get 252/282 MS, thats pretty fast with nitro lag Nullifier too

i currently overclocking my play to 1.6ghz and it runs fine.. games and apps run a lot more quicker

i'm quite interested in overclocking.. been thinking about it for the last months..
but i don't know, 1GHz is quite enough for me.. im not experiencing any slow down..

Well with 1.5Ghz then, you'll be amazed!

Setcpu or voltage control?

Which one do you think provides the best battery life and performance?

The one that shuts your phone completely off...LOL.
All kidding aside, the only thing I have seen actually provide better battery life with these is to lower the max speed. Even the author of SetCPU says you can have performance or better battery life, not both. I believe SetCPU provides more options for profiles whereas Voltage control lets you play with voltages which of course is very dangerous for stability. There are so many options in both that it will be hard to get a definitive answer and since every phone is different, Your Mileage May Vary.

With voltage control (and now setcpu), you can undervolt and overclock which could theoretically give you performance and speed. I'm a setcpu supporter, btw.

I'm undervolting with tegrak right now because I can't with setcpu. Definitely worth the money

It also depends what you are running. Voltage Control won't work with Gingerbread leaks and Tegrak with SetCPU is working nicely to prevent the random reboots in the leaks.

Regular CPU Settings or Reduced CPU for Battery

Does anybody know if having the normal settings are better or under clocking (say 1Ghz) for battery for this particular phone?
I also know that a higher speed can perform the calculations faster and thus save power. But, I'm just curious if there is a sweet spot.
Sent from my SGH-T999 using xda premium

Have you tried under volting, by using a custom kernel. Word of warning not all CPU built equal.
Sent from my SGH-T999

I'm using Faux's kernel which had reduced voltage setting already.
I'm just curious.
Sent from my SGH-T999 using xda premium

The best way to really tell woukd be to step the max freq. down by one or two and run it for a day or two. If it runs stable and you don't notice any issues you'll prob be good to go. My guess would be running between 1.2-1.3ghz would be a good spot.
I'm honestly not sure you'd see much difference in battery though since its probably running much slower than that most of the time its not sleeping anyway.
Plus I think I remember seeing somewhere that the power used to run at 1.5 is the same it uses to run at 1.3.
If your going to see improvement in battery its more likely you'll get that from voltage adjustments and your governor choice. You'd probably be best served by reading through the kernel thread to see what others have tried and reported.

It's more based on how the rom works, and the kernel yes helps with CPU and GPU scores but I noticed his GPU scores are lower than mine, one of the nation reasons I'm still stock. Because it's probably persues kernel and has issues with FPS in real world and quadrant performance.
He probably ran it 1600/1600 on performance or something on those lines
Edit: this is mine stock rooted GPU much better than his, until persues can match this without overclocking the GPU just to get the same performance I do on stock I'm not switching.

Maybe you should consider that you're not the brightest, most experienced person in this thread before talking smack.
Exposing a component to more heat means you are shortening its life, there is no doubt about that. Those with overclocked desktop CPUs often have elaborate setups with overclocking in mind. You can't add a better heatsink, or a fan to your phone. Mobile CPUs, especially, are designed to be efficient at a certain range of clock frequencies. Moving it too far from the norm means you eventually see diminishing returns.
I've fried everything from my first Commodore 64 to my current box, and everything in between. If you think the phone can function at that level for an extended period of time without failure, best of luck to you.

Dude it was part of the whole meaning of rooting and tweaking. Checking different settings for a little bit, testing them and then reverting back to defaults. I will never leave overclocked/ undervolted or vice-versa settings for a whole day... its just part of the fun of tweaking and experimenting with our devices...
Sent from my GT-N7100 using xda app-developers app

I am all for overclocking, modding, tweaking, hacking, etc. Breaking **** is the best way to learn. But that doesn't mean you should push your hardware past the point of exponentially diminishing returns, and increased risk of burning your chips out. That is, unless, you have no problem with the very real possibility that you'll need to buy a new phone.
That being said, kudos on "going plaid" with your Quadrant score

Its the Redpill v1.42... I prefer it compared to all the others i used ( stock, perseus, n.e.a.k., note2core). Those results were with stock rom but redpill kernel.

Hot and rooted

Title says it all. If I root my S3, it heats up to uncomfortable temperatures. If it's on stock, it runs nice and cool. Battery doesn't seem to be affected by this new heat. And I've tried a lot of kernels and ROMs. Why does my S3 get hot when it's rooted? And I'm not talking like gaming, I'm talking about basic use.

Clock speed is same as stock. Shouldn't be the problem.

My friends S3 used to get really hot and he wasn't rooted. I turned off his location service and no more heat. I presume the heat is coming from something that's running in the background. What rooting method are you using? Also you said you've tried ROMs and kernels. Is the heat coming from rooted stock or only when you switch to another ROM and/or kernel?

Give these a try. Better Battery Stats will determine if there's a wakelock not letting your phone truly sleep. And CPU Spy will let you know if your phone is getting stuck at any mhz or if it's sleeping.

If it's during use then CPU states. It might be running at higher mhz during use causing the heat problem.

that's what it's supposed to do. part of the "project butter" tweaks for jelly bean included this type of CPU jump when performing a task. that instant jolt to the maximum device GHz helps make doing everything on the phone more fluid/fast.
to get better battery on your device and troubleshoot whether this feature is hurting you specifically more than helping, feel free to adjust your max speed. start low, at say 1GHz, then bump it up a hundred at a time to find out where your phone is the most comfortable.

Can we maybe explain it as having a device that just run's hot ? It was my first inclination.
OP, maybe I glanced over it at first but you stated you have used many rom's and kernels and got the exact same response on all the ones you used ?
Did you you try going back to stock rooted and seeing how it was from there ? A completely clean slate might be your best idea. The only way a device will get hot is is more power is being used to keep the processor at higher temperatures. There really isn't any other way or than faulty hardware issue.

its not a price tag. its a script set to take advantage and make the most of the hardware on your phone. as soon as the task has begun, the CPU speed drops immediately.

I almost always use ondemand governor. In my humble opinion nearly all the other ones are inefficient or just placebo's. My phone runs streaming radio 4-5 hours a days on LTE and it never gets hot. Stays at around 918mhz at the highest. There a few bugs in 4.1.1 like the media server scanning where it will constantly scan your media because of a bad file.
Odin stock rooted 4.1.1 and then see how it goes. Factory reset it and erase /data or move to to pc or ex sd card. Won't take long and if it still does it I can't see what it would be.
