I'm looking to get some kind of battery boost by under clocking my HTC One S S4. Is it advisable to lower my minimum clock speed from 384 to 192, like I've seen on other phones? Or should i only under clock the max speed? I'd personally rather leave the max speed as it is and reign back only the idle clock speed.
Anyways, Im running the latest nightly. I was planning on lowering my clock speeds through CM. Is there a better way of doing this and managing speeds?

Why don't you try it and see? Just don't set it to take effect on boot until you know it works fine.

I'm having an issue with my phone not being responsive if I set the CPU to 400Mhz. I first found this problem using Juice Defender then I uninstalled that and did it under SetCPU and it still did the same thing. The phone pretty much doesn't wake up after a while. I have to do a reboot in order for it to work again.
Don't get mad at me but IMHO overclocking and messing with a phones core features (what makes it run, processor, ram, etc.) is unsafe and can cause instability. And no I have no scientific research to back this up but it's just my two cents.

Lol I'm not mad. I don't really like to over clock. I just figured under clocking would work better. But nooooo lol

It does that under 800 mhz I forget why but I've read that in a couple places

underclocking that much is using less than 1/3rd of your true processor power.
your processor simply is not able to draw enough power to perform its background tasks - even when the phone is idle - when you underclock to such an extreme extent. therefore, it freezes trying to complete these processes.
if you're going to underclock, i'd say that 800 MHz is the lowest you can go if you are expecting your phone to do everything it is supposed to do. although it isn't going to save you THAT much battery life anyway, so you might as well just run it at the stock setting of 1200 MHz.

I understand LOL. And he's right underclocking honestly doesn't
Save much battery.

There's a known issue with setting CPU profiles to less than 800 MHz. A fix exists but some kernels don't have it.
Many of our Gingerbread kernels fix it, Infusion-GB is one of the few that hasn't pulled in the fix yet. (Although version 1.1 may have pulled it in, haven't checked github lately.)
None of the Froyo kernels have an explicit fix, but I'm not sure if the flaw even applies to our Froyo kernels as the clocking architecture is VERY different.
Hi, Rogers stock 2.3.3
It's using up 60% battery over night. Most likely I should turn off Wi-Fi.
I have underclocked to 100, 200, and 400 and it's stable --- minus the delay/lag at 100 and 200 . Sorry to seem like a troll.
I find that by default this phone either runs at 100mhz or 1200 on average, and 200 400 800 under 10%

Bumping from 100 to 1200 is classic ondemand governor behavior.
Also, some people never had problems even without netarchy's sleep patch running the CPU capped to 400 - but others have. I don't think anyone has had a problem with a patched kernel.
Hey guys will overclocking drain the battery quicker even with stock voltages?
Sent from my Nexus S using XDA Premium App
Different voltages are specified as stock for different frequencies. As the frequency changes, the voltage does too. Running 1200mhz with the stock 1000mhz voltage will probably cause instability and crashing.

And if increase voltage, the power consumption should also increase.
i haven't played with voltages yet but in my experience the benefits of overclocking are minimal anyway, and they make nexus reboot often and other bad things :/
With the right settings you can get a fully stable and functional overclock, but it is on a per-phone basis due to varying quality of the same CPU during manufacture.

Currently I'm using icup kernel speedy 5 clocked at 1.4 and its been extremely stable. So what your saying is that the voltages automatically increase when I select a higher frequency, because I did not change them manually.

Open NSTools and select Voltage tab. That's the list of "stock" voltages for each frequency.

A CPU governor such as on demand, lulzactive and lazy tells the CPU what clock to be at and automatically change. While reading, it will be at 100 or 200mhz, while playing a game it will be at the maximum clock you tell it to. Saves power this way.

yes, usually 1 GHz is enough , UV or OC also may reduce hardware's physical life
you only under clock for battery right? i assume you over clock at home right? or is it bad to change it often? i wish there app that change cpu depending on location. is this possible?
Sent from my SAMSUNG-SGH-I727 using xda premium
Your CPU speed actually changes on its own rather often based on the load that it's taking on. For example, if your phone is just idling, the load on the CPU is close to nothing, so it's going to clock itself down to lower frequencies to save not only battery life, but itself from wearing out. Now say you're playing a game or watching a movie or something, it's going to do what it can to clock itself up to speeds to process whatever it's doing the best it can. Unless you have a STRICT clocking profile set up (say, min 1728, max 1728, performance), your clock is going to go up and down quite often. Download CPU Spy from the market and you'll see pretty well what I'm talking about.
Hope I was able to help!

I could not really see a situation where that would be ultimately useful, but yes download CPU Spy as the poser above me said and have a look at after a day's data gathering.
you should only have one cpu over clocking right.

I know that if you OC/UV incorrectly, it can cause stability issues. But I was wondering does it cause any damage to the phones hardware like battery, etc? And like how can you tell when SETCPU is causing problems?
Sent from my LG-P999 using xda premium
Well if you OC to high numbers your just stressing the cpu more.Knowing when you have issues is simple getting random reboots,phone getting too hot etcc.
It differs for every phone but undervolting -25 for each voltages works well.
Personally I really don't see the point overclocking to high levels like 1.4 ghz etc,Is up to individual I guess.

Yeah I have been wondering what's the point of OC to 1.4? Does it make that big of a difference in the 4g speed? And cpu speed?
Sent from my LG-P999 using xda premium
Honestly, there really is no point other than for benchmarks. I, like mt3g, actually underclock the phone to something like 750-760mhz; it runs beautifully smooth.
Other than that, if you game a lot and want to maximize FPS, then overclocking would do that for you.
Doesn't have anything to do with 4g speed afaik. That's entirely reception.
Yeah 4g is about reception and tmobile simply.
I mean I had single core devices like MT4g ,SGS 4g for the most part on a day to day basis transitions to transitions theres not much diffirence in terms of speed. Now for FPS and a few other games you need that dual core.Point is there"s no need to OC a dual core phone!

I have had mine OC'd to 1.1 ghz with some undervolts. It is very stable , 10-12 hr battery with medium to heavy use , and ofcourse fast. Took a while to find the best settings.
When I have SetCPU set to 1015 megahertz, that's the same as stock voltage, isn't it?

setcpu phone overclocking
Changes you might see are battery life but not that much unless you so how mess with voltage. Like other have said you know it effecting stability when its overheating, shutting down randomly, exiting program randomly.
Hi yes im new but not quite a noob :cyclops:
There with that out of the way my overclock settings are 1200mhz min 1600mhz max
so far running great with the HellyBean rom
But how would this effect my phone long term if any and I would like to be able to moniter my cpu temp like I do on my pc
but the thread http://forum.xda-developers.com/showthread.php?t=1140371&highlight=cpu+temp
has some good apps but they don't say cpu temp just the battery temp unless there interlinked some how
Thanks for looking
No temp sensor on the infuse except for battery.
1200 is really high for a minimum... This should be 100. For performance set governor to ondemand.. This will Max the cpufreq on any load. When idle, freq will drop and save battery and cool phone.
Running for extended periods at 1600 your phone will get very warm to the touch.. Combo of cpu and screen... If plugged into charger that will add more heat.
Battery Monitor Widget is a good app for tracking battery temp and related stats over time.

Thanks ya I figured it was a bit high
Do 100 min and 1400 max
And governor to on demand
Also i set up profiles with set cpu so when screen is off the maximum goes down to 400mhz.then screen on profile the max is 1400.it saves battery

How do you set up profiles?
Sent from my SGH-I997 using xda app-developers app
Use a CPU manager like SetCPU ($). Voltage Control or Antutu CPU Mgr may also have profiles.. Not sure -it's been a while since I used either.
Sent from my SAMSUNG-SGH-I997 using xda premium
The only ones I found so far that have profiles are pay for but once I get one I think its going to be either ROM manager or antutu
