Im using SiyahKernal and I'm curious about undervolting.
I want a safe/ok combo that will be smoothish and fastish but good for battery.
I'm currently running the cpu at 900mhz using extweaks.
Any suggestions? what're your settings?
Undervolting takes time and patience.
Start with -25 first and test if it is stable for a day or two.
If it is, move on to the next step.
Personally I didn't undervolt yet because it seemed to lower my average benchmark scores. Overclocked to 1704 and get 63k average in quadrant!!! (Not that it really matters in daily use...)
Yes do it in steps. The only danger is too low a voltage will cause a reboot when idle if theres not enough power to keep going.
I got mine to -100 for every step, stable. This means Samsung were generous with their voltages IMHO, but OEM's generally are. HTC are the same.

Thats amazing! how was your battery?
So the only danger is a reboot? no damage? apart from the obvious loss of work unsaved or game etc.
Not really bothered about benchmarking. just battery life with at least an 'ok' performance. i can easily set it up later when i need performance.
Just really love this phone and am mosty working all day.
Not really for undervolting. Its over volting that causes damage. Battery is ok. Not amazingly better. Cell Standby is killing me.

yeah cell standby is a big hog. it drains more than 45% of my battery every charge

I have seen a lot of people talking about horrible battery life and have to simple pointers to get great battery life
#1 underclock to just around 1ghz; I have mine underclocked to 1.08 GHz and am at 7hrs on battery and still around 70% with mild usage a vast improvement from before where I would have 5 hrs and then be at 10%
#2 facebook live stream sync seems to never fully sync I had it set to sync once a day but it would sync for hours and then 30 mins later start syncing again for hours I thought it just was an initial sync thing but it has done it for about 2 weeks now I have been on the same Rom for this time only thing I do is wipe cache and reboot every other day which is sad but whatever cus I really like the friend widget with facebook statuses.
Just wanted to give you guys some advice also in the ics/sense3.6 roms I have noticed V6 supercharger to be a vast improvement on the stock kernel just because of how it regroups app and level the oom at a reasonable level.

ive done all the tweaks and i still get shady battery life when using the device.
Thanks for the tips dude.
I did notice that a lot of the facebook syncing would take forever to complete. I'll try your tip

I suspect the screen to be a little to good. The density and size our against us I think cus my friends wife has a huge Samsung note and she gets like 9hrs from a full charge so something isn't right.
You have tried what I'm talking about though huh? Cus I noticed a huge improvement by underclocking to 1.08 and 128mhz on the low side also the conservative govner will lag a little at such a low CPU rate but helps to but with on-demand and underclocked I have no noticeable lag

Get juice defender from the market and set up a customized profile. This will turn off your radios when not in use and if you want there is still an option to have it turn on and sync every so often. Works great for me. Today I had 16
hours unplugged with screen on for almost 3 hours and I was still at 49%. This is on an extended battery so take it for what its worth.

OK changing the question: what are the differences between 729 and 787 as Max for you? Don't answer if your phone crashes! What are the differences for performance/battery between them?
The highest level you can OC is 864Mhz. It affects CPU life and battery life A LOT!
Decrease the CPU speed can save the battery, but it also can make your phone slower...

Hehe you answered exactly how I expected the answer... I expected, but not wanted, already knew
Does setting to 787 decrease CPU life (heard of any G1/G2 with burned CPU?)

In my opinion I think after some time over clocking your going to come across some problems like battery frying phone over heating I haven't heard of anyone's CPU frying yet but it can happen but I think by the time you have used a few roms and done some experimenting and something dose go wrong a new p500 only going to cost u around £30 just take the risk
> about OC'ing, it affects diode life, chips are made with diodes, and it is computer related aswell, overclocking causes cpu diodes life to be shorten out, overclocking means more current, more current means more heat, more heat will cause diodes to be busted out easily, but I never head anyone here complained about a bricked O1 becoz of over clocking.. this is as far as i know, I also want to know if 600 and 806 are in same voltage? ta kernels had this undervolt features.. it means lower voltage some frequencies isn't it? but undervolt causes more heat, why?
I have a 787 MHz maximum stable frequency. In the matter of performance / battery life to save the answer is simple:
The higher the frequency of the processor, the better the performance, but consumes more battery power, as well as its temperature rises. To play well, the battery is bad
i m using cm7 stable rom on my p500........with overclocking min 480/max729 ,governor-performance,scheduler-cfg.....
is there any effect of overclocking on battery life or performance on mobile?
more performance but lower battery life.
Mmm ok I have some questions, what is a normal overclock to improve battery life but without sacrificing a lot of performance.
And the other way around, an overclock that improves some performance without sacrificing too much battery.
What are the "optimal" values of an overclock (Without making the phone unstable)
I would just overclock until you get phone instability or you go as far as you can for the current kernel (I'm on AOKP 4.0.4 and it's 787 max which is what I'm at).
Battery life doesn't get affected that much because it's mostly drain when playing games where it ramps up to the max clock speed, at which point you're draining a lot of battery anyways.

Thanks, I also have AOKP so I'm going to work around it a bit, how can I test stability?
Go to Rom Control.. Performance.
Remember to UNCHECK " Set at boot" option.. so that if anything happens.. it can return to default value after a reboot.
If random reboots or white screen appears or phone hangs.. its not stable.
I'll rephrase my question, what type of test can I do to ensure I have a stable overclock. I don't want to find my phone turned off out of the blue and maybe missed an alarm or what not. Thanks anyhow for the tips
Just do general usage. If it works fine for 2 weeks at a specific clock, it's likely to be okay.

You will only know by using. The CPU manufacturers label a chip ancertain speed because it fails a test at the next level. That means that some chips can handle faster than others. They are guaranteed to be stable at the rated speed.
There is no formula

Not necessarily. Voltage and heat are usually what kills electrical components. Since our device can't change voltage for the CPU, that point is irrelevant. However, heat is a factor but AFAIK the heat from overclocking doesn't increase that much for this device, unlike something like PC CPUs so that's fine as well.

No, you can damage it. If it heats up, then:

Hello friends,
I was feeling little wariness while I am holding my device in my hand and when I checked my device temperature with Cpu-z I got these readings. So please confirm is this really a concern for me or not.
Thanks

Woah buddy those are some heavy temperature readings there. I have not encountered any heating issue except while installing custom roms or using the phone while gaming in high brightness. I think the fact that you were using your phone while it was being charged increases the device's temperature greatly and caused the problem because even my device heats up like crazy.

These readings I noted after my phone booted up after 'optimizing apps....' but truly speaking I am feeling only little warmness.
While charging my phone temperature fluctuate between 45-50
This is my current temp reading while I am charging and typing this reply and I am feeling only little warmness[emoji14]
Is this reading normal or I have anything to worry about[emoji14]
Thanks

It is normal for the device to get warm when it reaches the optimizing apps screen because the brightness is set to max at default and processor is continually used. You have nothing to worry about mate.

Yup, it's pretty normal. Also it shows cpu temperature not your device's temperature. I can see that you have boeffla kernel installed, so be aware of modding too much with kernel settings. Thermal throttling is enabled in the kernel so no need to worry.

Mine is -100mv on blu.spark and Ashwin's CM13. Never had any problems with this voltage.

I'm always using - 100 undervolt.
Sent from my ONE E1003 using Tapatalk
I'm stable at - 95
-100 was unstable for my OPX
Working on Swell-V8... I'm quite happy with this setup
It depends on individual phone. Subjective
Here is my setup. Using Boeffla's kernel and his app. Also, with this uv profile there are no more overheatings. The phone stays quite cold even on gaming and stuff like that.
-75mV overall. 100 was a bit unstable, maybe 90 could work but this way I'm completely safe.
As I already said, I'm on -100, but I still have high heating... 55°c when playing Minecraft for 20 minutes.

Did you undervolt to an overall value or different for different frequency?In OOS, I had freezing even with - 25 mV.

How do you do that? Once i tried, hit one wrong voltage, and phone never booted to system.

Patience. You find the lowest for each in 25mv increments and from there tune them. It's tedious. Obviously if you enter a random voltage then it don't work. If you don't entirely unfetdtand PLEASE read up on it or you will fry your phone
Currently at -100 to -125mv on Boeffla. No fc's or reboots since I started using these voltages.
-100mV on BluSpark kernel, no freezes, no reboots.
If you use Kernel Auditor, "Boot on system start" gets activated several seconds after the phone has started, so you can revert any errors in normal cases.
I can go -60mV, no more on bluespark v128.
If i go more than -60mV, i get reboots sometimes after 12hours or after 2-3 days
