Overclock

If anyone out there has overclocked there phone, does it still run well after a few months etc.
I plan on rooting and overclocking to 1.5ghz (on demand) and just want to know if it will wreck the phone after months of use. I am aware overclocking is not recommended for long periods but just want to see if people have had hardware issues after prolonged overclocking..
Thanks in advance

Its not the clockspeed you need to worry about. It's voltages that can damage the H/W.

So using SetCPU to 1.5GHz changes the voltage?

Well the higher the clockspeed the higher the voltage. Kernels like doomlords allow you to undervolt though. Keep in mind if you reduce voltage too much though, device will become unstable and reboot alot

Im currently running at 1.5GHz and have IncrediControl running undervolt at 1200 (tested for few hours seems OK so far)
Does this mean I am correctly undervolted and are these settings ok for battery life/temp etc

If it has been running well so far, I don't think you need to worry.

Just wanted to make sure undervolting doesnt cause damage to the cpu and battery

Undervolting wont damage the CPU. As long as it's stable, the less voltage the better

[Q] Battery swapping

I bought an 1800 mAh battery and was wondering about swapping between the 1500 and 1800 as needed -- will this mess with the battery stats?

No. Percentage is based on voltage.

Just so that you don't second guess kennyglass123, I second this. I swap between the stock 1500, two 1800s, and one 3500 all the time and have no problems.

Thanks for the info. What does wiping battery stats do then? Is that specific to the rom rather than battery?

Not a heckofa lot. It actually has little to do with battery calibration. Your battery goes from 4.2v which is 100% to 3.7v which is basically 0%.

Source for the 1800?

Are you asking where I bought it? Just got the official Epic 4g Touch Samsung battery off amazon.

Charger output

As I was putting my S3 on charge last night for the first time I noticed that the output of the new charger is 1A as opposed to .7A on the charger for the S2.
As the S2 had theoretically two charging modes, 450 &650mA (depending if it was enabled in the kernel..eg Siyah), I was wondering if any of the tech guru's out there would know what charging rates does the S3 accept (if kernel enabled of course) ?
I'm guessing this would have to be done with an ammeter but if anyone has any theories feel free to post here.

Hopefully GM of SiyahKernel fame will have an answer and tweak for us in no time in his upcoming kernel. I'm sure it'll be in his to do list somewhere.
Edit: First charge 4-100% in 3 hours.

Anyway. Good to see you over this way.

whats the max battery voltage??? with 100 % charge i can see voltage upto 4.3xx

1st charge got 4328mV.
Expect it to be a little more after a few full uninterrupted charge cycles.
Suppose I could do the maths and calculate an approx charge rate, but will need a true min. for that. Brain's a little tied right now though

ah , 4328mv ! im getting something closer to it, will get better with some more battery cycles.

4338mv measured here peak. I
Also. 999A being drawn.

No, but I believe its locked at 1mA.
Using siyahkernel with extweaks app and there is an option to increase this.

Show Off Your Overclock Settings

OK.First of all,I'm sorry if there is a same thread like this.So show a screenshot of Set CPU or whatever application you use to overclock and post a screenshot of it.

oh god, not another thread

I usually use smartass though..
Btw what app are you using? Is that setcpu?

You stuck Max and min to 729 MHz? Wow that must drain battery like crazy......

Lol yeah. Why not set governor to performance instead?
My phone becomes unstable above 748. Is it because i'm using stock kernel?

I am sure you can take this to the numerous threads already open on this topic.

Nexus 4 running over 100oC safe??

I was messing arround with overclocking and undervolting. after f*****g up my app data with a "bad" undervolt I had a look at overclocking and I get over 100oC and still rising running at 1.7GHz is this normal? I have a fast binned chip
Sent from my Nexus 4 using xda app-developers app

Also getting over 80oC on stock!
Sent from my Nexus 4 using xda app-developers app

Well the bar only goes up to 100
What does that tell you.
Bring down your oc dude.
The CPU safety threshold is 110.
Meaning if it gets to 110 your phone will shut itself down to prevent damage
Sent from my Nexus 4 using xda app-developers app

Thats all I wanted to know ... But 80+oC is insane for stock!
After undervolting its 75-78oC but that 3x more than my gaming PC!!! (And 2x the GPU temp)
Sent from my Nexus 4 using xda app-developers app

Well what are you doing to cause this heat. On both screenshots you are showing Max load. Max CPU freq at quad core. Of course your CPU is going to be overheating.

if you wanna go mental with O/C, you should go for watercooling or liquid N2

haha, although I did apply thermal compound to my galaxy 5 and it was a lot cooler (it has a metal thing that is conveniently over the CPU
Sent from my Nexus 4 using xda app-developers app

While gaming (or what ever you are doing to get it that high) have someone stand behind the phone with an upside down can of compressed air blowing on the back of the phone. This should help.
