Underclocking question

Hey!
Just watned to ask, can't underclocking possibly damage my CPU in some way? I'd like my phone to be alive as long as possible, so I thought I could underclock it to around 700MHz and to minimum when screen off.. but won't it damage it in any way?
Thanks

No, it will not damage the CPU.
Actually, because the CPU will not get as hot as with overclocking, underclocking might extent the live of your phone.

yep thats true, also, if you are underclocking for the screen off profile, why not go right down to 245mhz? I did, and the battery life was MUCH better!
hope this helps! good luck !

Indeed. I do the same thing and this does wonders for the battery life!

yeah sleep profile of 245-245 battery life is about 12 hours better at least.

strange that. ive just uninstalled setcpu because i couldnt see any difference in battery life at all

I agree set CPU with screen off profile, so better battery all together.

Thanks guys... I've now underclocked too and I now no longer have to charge twice a day!

Overclock Nexus CPU?

Will it be possible?
From anyone in the know, are we far off from a CPU OC kernel?

why?! The battery life is mediocre as it is!
Undervolt/underclock could be useful tho.

the screen and the radios are what drain the battery the most.
overclocking won't make a big dent on battery life. but better clock speed management may actually improve battery life.
To answer the OP's question, It's inevitable. the chip is a TI-OMAP, and the original Droid came clocked at 550mhz but was a 600mhz chip. It was able to Overclock to 1.1-1.3GHz stable depending on the persons phone.
I'm not saying we'll see a 100% increase on the Nexus, but It's hard to imagine not getting past 1.6 GHz considering the chip is actually 1.5GHz.

[ROM Custom] Overclock

Gello guys,
(I'm on MooDed ICS 1.0.2)
I wanted to know what kernel(s) is (are) the best to overclock the Arc and to what frequency can I go with the phone stable? I'm actually on InFamous Kernel ( http://forum.xda-developers.com/showthread.php?t=1843532 ) But I'm not overclock. I was before on DooM Kernel and overclock to 1.2 gh/z.
Thanks a lot! (And sorry for my bad English, I do my best)

It all depends on your phone. Even though there all made the same, some of the processors can not handle the same amount of OC as other do. The way to test which runs most stable is to slowly up the frequency every hour or so, and test it to see if it's stable.
If your phone starts to random reboot, then it's probably best that you choose the lower frequency to what you are using when it reboots.
I'm using inFamous Kernel too, its overclocked to 1.5.
1.4 should be theoretically safe as that the speed that the Arc S runs at with the same processor
EDIT: I don't recommend passing 1.5 on the Arc as it will very quickly burn out the processor. (Even at 1.5, it's running 50% more than what it was originally designed for).
Overclocking will also reduce your battery life. So it's swings and roundabouts depending on if you want performance or battery life.
Hope I helped

Over cloking is realy affect to battery life and all so the head will get increase,
am always usting 1.2Hz.i think it is enough to have a smoooth run for a xperia smart phone while saving the battery and reducing the risk

Ok thanks guys! I'll try all I can. I'm now overclocked to 1.2 ghz and battery life is good for me, because I recharge it all night. At 1.4 ghz, it's stable normally but the CPU is hot (very hot) and I don't want to burn it. But is it normal? Because Arc S is on this frequency and isn't normally so hot
So Thanks one more time!

Yeah, don't worry about it getting warm. If it gets really hot, then I'd recommend to stop using it for a while. Simply to let it cool down.
Mine can get to the point when it feels it's going to melt the plastic on the back yet it still works perfectly, so yeah i'd say its normal. There's also a ton of older threads about how much peoples arc's heat up when it's being used.
The reason why the processor gets so hot is because there is very little heat sink because of how thin the arc is.
Obviously the more you overclock the hotter the processor will get. The hotter the processor gets, the more quickly the CPU will burn out. If you don't like to replace your phone every few years, don't overclock it to the limit.

You should OC stable at 1.2 - 1.4 GHZ

Ah ok thanks.. I like to change it every year / 2 years. And now I'll try Puissant phone like GS3 and others.
I've overclocked it to 1.6 and it's stable (fast..) and hot. But I'll follow your advices. Thanks a lot!

dont overclock over 1.4Ghz if you have arc and you can always undervolt to save some battery juice

Ok, but I didn't find thé option to undervolt where is it?
Thanks

U need apps for undervolting such as setxperia, voltage control, etc.. Reduce the voltage and test it for few mins then again lower the value until ur phone auto restarts. Tats the threshold value

Is it possible to undervolt it if it's overclocked?
Thanks

yea obv..undervolting means supplying less voltage to the cpu at specific frequency. it doesnt matter at wat frequency the phone is running

It might work fine well above 1.4 depending on the quality of the CPU you have in your device. I am fortunate enough to be able to overclock an xperia arc to 1.8 GHz and have been running at this clock for 6 months. Even gaming at lengthy time with charger plugged in works fine.
I do not game every day and just listening to music, talking on the phone, texting, reading a webpage or watching a video will not run the CPU at full speed all the time. Battery live if also fine for my usage 1-3 days. I prefer a snappy and responsive phone.
Running at very high clock speeds is at your own risc, the cpu chip design should be able to handle the high temperatures. I have allways overclocked my phones and have not yet been able to kill any of them, maybe I have just been lucky. There could be a poor soldering that breaks when it heats up, only push it to the limits if you can afford paying for a new phone

1,6 GHz on XArc by Sirkay = epic speed.

best way to get battery life with R800x?

I know this is like the 800th thread I made about this but, I have 2 3600mAh batteries, both sometimes draining within a day... =/ I bought them from ebay. A few other people bought them on this forum too. The batteries I bought were...
http://www.ebay.com/itm/Extended-Ba...ccessories&hash=item27be19414f#ht_2727wt_1163
This battery has lasted me well, but could it be the way I'm charging them? With the wall charger it came with? Should I just let the phone die completely and let it charge via USB in the phone itself or what?
I uninstalled Juice Defender, Kik Messenger, and other apps to see if I was eating up my battery. My ROM is the UK 2.3.3 and I'm overclock with...
No-frills CPU:
Max clock 1.306GHz
Min Clock 364Mhz
Governor smartass V2
I/O scheduler deadline
If you need anymore questions please ask. I'd like to get these batteries working as well as I hear all these other people using theres.
Thanks in advance.

Way to get best battery life? DON'T OVERCLOCK

Idk what your experiences is it may depend on what brand of battery your using. It may not be true 3600mA battery I have a MUGEN battery 3600mAh and that battery lasted me 2.5 days with moderate use but my settings are low brightness, turn off wifi when you dont need it, no overclock. But if I keep the same settings and I overclock to 1.2 ghz I get about 1.8 days worth of battery life. Do you get the picture dont overclock for long periods of time.

I was replying to the guy that IS overclocking. If you were to overclock, your battery life would be even worse

[Q] Best frequency for overclocking with battery life in mind?

For the people that have been overclocking this phone for a while now, what are your opinions on the best max frequency above 1.5GHz to clock to while still keeping decent battery life?

Overclocking isn't exactly a battery friendly thing to do, you will see battery drain if you clock to higher frequencies. My only advice is don't oc too high if you want to keep battery life in mind. Going to 1.67 or 1.72 should give you a decent speedup without murdering the battery.

I run mine at 162 its no diff in voltage from 151 at least on uber kernel it is.. Also try to under clock the the freq until or happy and no random reboots
