does overclocking damage my s2?

hi just wonderding if i oc my s2 to 1.7ghz win min 19200 will it damage my phone in any way?

I'm sure this is up for debate but obviously overclocking you're going to be working the hardware more than the manufacturer intended, potentially causing more heat, early component breakdown, poorer battery life, etc.
I'm with the darkside devs on this one. I've actually got mine a bit unlocked to 1.29 GHz and it works great and the battery lasts nicely. As they've said, overclocking isn't really necessary when the hardware keeps up nicely to any game you play on it or when you're navigating menus or websites on it.

What are you using to underclock because many are saying not to use setcpu?

System Tuner is good, however I would recommend staying away from overclocking period. As the other poster sited, you can fry your chip by placing unnecessary stress on it.

How hot does your S3 get?

When I'm on mobile data with GPS running, I noticed the bottom of half of my S3 getting pretty damn warm. Is this normal?

Just started using mine I'm feeling the same heat

No heat here.. downloaded a 840mb file over 3g for A span of like 3 or 4 hours and didn't get any heat at all

Mine also gets quite warm. I can't believe yours wasn't cooking after downloading that file

Are you guys all running stock kernel and ROM or custom? I'm on stock.

Ha! Try hours with GPS, Bluetooth music and Tethering on... the heat seems to really hit while I'm charging and doing all that. Fact! I can't touch the ass end of the phone. It probably gets about 8 hours a week like that. Still working perfectly. Samsung tells me it's normal. It also has a lot of factors for me too. I use a 1 amp charger. After 96% it's not so bad. At night when brightness is down. Not as hot. I tried to get it to mess up but couldn't. GPS, Bluetooth, tethering, charging from 30% and 100% display, and I pushed out to a low coverage area. Didn't miss a beat or melt. Lol.

Navigation makes phones really hot, but with normal usage it should stay within 30-36°C.
I like this phone's heat management more than my old phone. My Evo 3d would get hot from 10 min usage.
On this, my screen has been on for 2 hours straight and I'm running at a cool 35.1 °C.

When I was running CM10 for a day or two I thought my phone would melt but it was also 90+ degrees outside so it was hard to tell. My phone gets a little warm, but nothing too worrying.

When you downloaded that, were you on stock ROM and kernel?

This is to be expected. It is pretty high clock rate too but seriously a huge improvement from the gs2

It actually shouldn't be expected. The Snapdragon S3's also ran at 1.5ghz and was pleasantly cool and the Exynos on the Galaxy Note was at 1.4ghz. Both are less power efficient and should run hotter than the S4. I've used the Evo LTE for a while with the same S4 and it barely got warm on a hot day. The issue is with the second core being weird. For those that hasn't already, make sure you flash Freeza's fix, http://forum.xda-developers.com/showthread.php?t=1790061 . This fix made my phone cool and got rid of my quickly draining battery life.

Most of the time my phone will stay within "normal" (to me) range, but when I game heavily... it turns into an oven range! I've gotten so paranoid a few times, I took the battery out and let it cooled for 5-10min

Im having the same problem....it isnt the software thats causing this its the hardware
Sent from my SPH-L710 using xda premium

I hope you guys will repsond to this... What do you consider to be "normal" temperature for your phone to reach? Is 35 degrees realy normal? Ive heard people with s3 talk of theirs only reaching temperatures of 29 degrees max.
Thanks.

Does force hw acceleration do you more good or bad?

How's battery consumption compared to not forcing it?

Usually forcing the use of GPU does cause a difference in battery life, but the difference is unnoticeable. Maybe half a millisecond less of battery life.
Edit: My info may be wrong. I just read this in ICS days in a similar thread.

It should increase battery life since hardware acceleration usually means less stuff for the CPU to process which equals power savings.

I enable it on every ROM i use after ramping up GPU to 384 without really thinking about it. Always has been solid for me. And yeah, im gonna say that it doesnt do a 'whole' lot for battery. But hey, another 5% on a charge? I'll take it.

I do - I undervolt it to 800mhz using the profiles function in SetCPU and have already undervolted the 800mhz range and below by between -25 and -50.
I know it uses hsdpa, gps etc so it is battery hungry - if you struggle on power look at getting one of those power packs (10000ma)
That would keep ya going all day haha

The phone seems to run comfortably at 800mhz however can take a tad longer when taking hdr pics or doing anything processor heavy. I tend to use the profiles option in setcpu a lot

4-5 hours of battery life.

I don't understand why but my phone is dyeing way too quickly and it's not so responsive (feels sluggish) as I want it to be. I see my friend has his HTC one and it's substantially faster then mine, both of us running all stock (mine is stock Rom but I'm using leankernel 6.8). I downloaded Better Battery Stats and I don't really see anything jumping out yet my phone usually lasts 4-5 hours with about one hour of screen time, sometimes I'm able to squeeze more. I have 90 apps on my phone, everything legit. I feel like it used to be much better before ..
Please advise.
Sent from my Galaxy Nexus using Tapatalk 4 Beta

the HTC one is faster. more memory, better processor. so thats a terrible comparison.
4-5hrs of screen on time or just 4-5hrs total?

Is it _THAT_ faster then GNEX? I'm running leankernel, mine is slightly OC to 1.2GHz. It seems like sometimes I could be running one or two apps and my phone would be really slow.
4-5 hours to drain 100% battery completely with about an hour of screen time.
Sent from my Galaxy Nexus using Tapatalk 4 Beta

its a quad core vs dual core, 2GB of ram vs 1GB of ram, so yes, its that much faster.
are you in a bad signal area? low LTE area (i assume you have verizon). give me a screen shot of your battery usage.

I'm not using LTE, I switched to 3G to save battery, right now I'm getting 3 bars out of 4 (-83dbm 4 asu)
Sent from my Galaxy Nexus using Tapatalk 4 Beta

looks like you're playing music the whole time over 3g, correct?

That is horrible btw.
My Verizon is running on 47min screen on time with 7h 15m 14s on battery and I have 62% left.
I'm not doing anything special with my phone either regarding "saving battery". Just standard official AOKP. No special kernels, undervolting, no special apps, etc.

its possible. you could have undervolting too low, kernel could just not like your phone, etc
try with stock kernel, if you have the same results, we can go from there.

I don't really "undervolting" or any other tweaks other then install leanKernel and change "Power Mode" to "BestBalance" (it sets following: MaxCPU: 1305MHz, MixCpu: 384MHz, Governor: interactive, IO Scheduler: deadline, MaxCPU (screen off): 537MHz.

I don't really see any difference, but if you think it'll help me, I can try setting it to 1.2, although I'm pretty sure this isn't why I'm getting so little time on my battery..

3g does use less power than 4g,but it still drains pretty fast. Use wifi whenever possible. Turn on auto brightness for display. If u have the Facebook app, delete it and use the mobile site.

If I was beta testing an app, I would try to have a very small number of installed apps.
AFAIK, the longer the device has to keep a wake lock, the harder it is on the battery.
And 1.2 GHz is stock max speed, not an OC implementation.
