Overclocking and better batt life? - Sprint HTC EVO 4G LTE

Ok, so I'm not a cpu guru, and have heard that overclocking actually gives better battery life. Can someone explain how this works or if its true?
Thanks

Or that a turbo/hemi is fuel efficient *cough cough*

I'm no computer scientist, but I have over clocked my computer and researched a lot on it before I messed up a $700 cpu. When you over clock, you can usually get out a little from the cpu without upping voltage, but to get a decent amount of OC, you have to increase voltage which sucks your battery.
So a generally answer is that it decreases battery, to my knowledge.

I think the "myth" that overclocking saves battery stems from the idea that if your phone is working faster you can get things done faster and won't be staring at a lit screen waiting for something to happen.
My personal thoughts on OC is that it may yield higher benchmark scores, but doesn't affect my day to day usage other than decreased battery life. Maybe on my 528mhz HTC Hero it was helpfull but not on any of my current devices lol

maybe

Maybe they meant underclocking. My kernel on my shift right now allows as low as 61mhz . And as high as 1.9 ghz. (Drob311's).

[Q] How To Revert Back To Default 30FPS Cap?

Hi Guys...
I've Already Uncapped My X10i (2.3.3) To 54FPS, But It Seems A Little Bit Eye-UNFriendly In Scrolling Or Some Other Stuffs...
I Wanted To Know Whether There Is a Way Back To Factory 30FPS or Not?
If There Is a Flashable Package Via Recovery, I would Be Thankful To Provide Me So...
Thank You In Advance...

I just did the fps uncap thing and youre right its fast(awesome) but if its uncomfortable for you, you should get try doing the 34fps uncap, it will be slower i think
Just search for in the forums "fps uncap" there will be a topic about someone wanting to go back to 34fps, download from there and flash thru xrecovery

I think 34FPS is still a Modded cap, since the original is only 30FPS, I need the original because I want to get rid of battery drain, too...
but anyway, thank you dude, every word you type makes me owe you one

Well, you got me in a boring night so i started looking around but couldnt find the original.
You gotta keep looking but if you.dont find anything, back your apps with titanium and flash doomlord's pre rooted image, i know it sucks to do a fresh start but the battery is worth it.
This is just as a last resort though

r u sure there isn't ant battery drain?!!! my battery sucks after flashing this mod, although it performed pretty decent before flashing 54FPS...
but as u know, there is no way to precisely monitor the effect of a single mod like this on the battery life...

Why would anybody wants to un-uncap the FPS? That has nothing to do with battery drainage.. Also I don't get how an unsmooth scroll animation does not hurt but smooth one does?

First of all, as I said before, anything we say about battery drain is just an estimation, there is no way to precisely calculate how much battery is used more than before applying such mod.. Then I said I just FEEL that drain, when people like you, and other friends say that it doesn't, so I put trust in you
and about un-uncap, what you say is basically true, higher fps gives better smoothness of overal performance, but that happens only if GPU is capable of doin so, a weak Adreno 200 is not somthing brilliant at that render, especially running at these goddamn kernels of SE. also Vertical Sync seems to be disabled in order to reach that 54fps, which gives the screen a little bit annoying refresh rate, THIS is the ONLY thing which bothers me, and we are still in the same boat that it gives a UNBELIEVABLE smoothness to the device
now, if you are sure about battery drain, then I will keep the current setting, since as you said, it is really nice and smooth
thank you bro, thanks for everything

I think you are uncomfortable with the tearing that occurs occasionally, i think that we should wait for an fps cap at 54fps so it doesn't tear as much as 54fps uncap.

YESSSSSSSSSS, that's the point, I think you're completely right, because constantly changing fps is the thing which hurts the eyes, if sb (for sure Z!!! ) could find a way to cap it to 54fps, it would be great...
Disabled Vertical Sync is annoying

So Android OS has a bug

http://www.xda-developers.com/android/android-os-what-is-it/
this is crazy no wonder are phones battery dies fast, I wish the devs in xda can find a solution
http://forum.xda-developers.com/showthread.php?t=1290020
^^^^^link to actual thread
From my understanding, this is an Samsung driver/kernel problem (not really clear as to which one) and doesn't affect the Evo 3D. Also, I think this bug prevents the phone from sleeping, which isn't a problem in the Evo 3D.
I could be wrong. I'm tired and haven't read most of it.
That's one hungry bug. Interesting to read though. Thanks for the post, u haven't heard about this.
Sent from my double barrel Shooter. BANG!
Just skimmed this via the xda app and not sure I agree with it all. I don't see this happening on my phone nor did I on the EVO 4G. I use system panel pro to purely monitor battery and app usage. Never use any task killer as they do more harm than good.
Just would of thought if this was a real issue it would of been pointed out before now.
I don't agree with using the stock OS battery usage though to guage it though as its not detailed enough.
I'll wait till xHausx or Net or another respected dev looks into this before really taking a side.
Just the bug they explain with CPU getting pegged seems like it would of been found by now if its real.
Least the fact my EVO 3D sleeps just fine. Prolly a Samsung issue. Yet another reason to not buy Samsung. Lol

Never ever had an issue like whats described in the thread, on my EVO4G. Though I wasn't around for the GB update to it so if it came after that OTA then I would of missed it.
The thing with going by the Android OS % use thats built into the OS by default is that sometimes some apps that get stuck will get tossed into that %, making it missleading. Hence why I use SystemPanel Pro and have monitoring on so I can track detailed use of everything and it breaks down the system use too so you can see what process of the system is running the most. I've seen times where Android OS is high but then check System Panel and its not at all abnormal and its really a App that has gotten stuck.
regardless I have yet to see anything close to this happening on the 3D which leads me to think its not really an "Android OS" problem in itself as much as its to do with the manufactures modifications to he OS and kernel more likely.
I will say though most of the time that I have experienced any battery drain it has been an app that is continuing to chew CPU even after backing completely out of it and not using it for 10-30min even. Seen it with the xda app sometimes and it seems completely random as sometimes when i back out of it, it closes the app fully and it no longer is eating away at CPU. Also seen it in my DBSTalk app too, both clean installs also.
---------- Post added at 07:41 AM ---------- Previous post was at 07:24 AM ----------
EDIT:
I might be taking back what I said about it not being in the EVO3D here. Just checked systempanel and looked at a weeks worth of time frame when looking at the "suspend" process and there is in fact 1 day where that process is higher than the rest and battery life is worse that day too.....
Will keep a closer eye on that process and see if I can catch this real time doing it myself.
still looking forward to Treve, xHausx, or any other respected Dev to chim in on this from an EVO3D perspective and get their thoughts on the thing as a whole too.

Battery on CM7 and CPU speed

I've flashed cm7 yesterday and I've noticed that the battery life isn't that good. Is it gonna get better? I recalibrated the battery last night and I've seen little improvement ...and is there a way to change the CPU speed?

You might be stuck with the battery you have post calibration. As far as CPU speeds I believe you can slow down the speed but you cannot speed them up. We need unlocked bootloaders for that

Didn't mention that you can use ROM toolbox or the CPU manager found in cm7's settings to mess with CPU speeds.

I've tried changing the CPU speeds in those settings but nothing is changing. When I try to go to a lower speed, it just stays the same ... Any idea why?

Give the rom a couple days to "level" out. I just flashed eclipse 2.1 on my room mates phone and the first couple days his better life sucked and then it better and better, I suggest you do a battery calibration, some say it works others say it doesn't. I feel like it does.

Ight I will. I'm really loving this ROM
One thing I've noticed between the Blur-based ROMs and CM7 is that it seems that the display uses a lot more in CM7. On Blur ROMs "Phone Idle" has the highest % and on CM7 it's "Display". I've tried dimming the display and/or shortening the timeout but it doesn't really make much difference.
Also, FWIW, battery calibration is useless: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT

Is it possible to overclock this phone?

Title says all. If possible, to how much can you overclock it?
Honestly, I don't know why you would overclock for anything other than bragging rights. this thing is fast.
All it needs is for the software to be optimized.
Undervolt is always good too.
Sorry for not really answering your question, but i'm sure it's possible. I mean, if you can undervolt, I'm sure you can overvolt and mess with the multiplier and all that jazz.
http://forum.xda-developers.com/showthread.php?t=2012320
That is what I'm talking about. International only though.
From what I've gathered from reading various posts, it is generally frowned upon as a bad idea for a variety of reasons, ultimately coming down to it will end up damaging your phone one way or another. So, yeah, of course, I'm sure you could find a way to do it, but if it were me I wouldn't(and this is coming from someone who overclocked every modern phone he's had except this one).
Once I see the trusted devs talking about it and saying it's a good idea...that's when I'll try it. Just my 2 cents.

Have you ever actually run into a situation where the phone does not have enough cpu power? I know I haven't but there have been many situations where I wished I if more battery Mah, what you really want to overclock is the gpu which is stable running at about 600mhz. The main reason why the cpu might not perform well is due to the cpu getting stuck in single core mode or failing to scale properly, just head over to nik3r's or maxwen's kernel threads and flash the latest version.

Overclocking and people with EOS (Extreme Overclocking syndrome) care little about if they need the extra power for a purpose. There sole mission is to push a CPU as far as they dare without frying it
This is fine with a PC, as PC's have all manner of 3rd party cooling solutions. But I totally agree with everyone that trying to overclock the HOX+ CPU is futile and borderline stupid. It struggles to keep itself cool at the best of times. Putting the CPU through extra thermal stress for no reason and to gain little in the way of performance is not something I would risk....

[Q] Soft undervolting (-25 to -75)

Right now my rom and kernel is stable but would like to have a little more battery life and consider undervolting a little.
Just wondering whether the gains of soft undervolting (-25 / -50 / -75 across all steps) are visible in terms of increased battery lives for our GS2. Anyone did any test/comparison to determine if your battery life is better/ overall temp of device is lower?
Thanks in advance!
Get Gsam battery monitor from playstore and under volt -25 and test for 2 days aleast for freezes and sods. Then drop to -50 and so on. Some phone wont drop by -25 without sods. Also setting cpu to 1000mhz Saves battery not having to jump to 1200.
In my experience, some increase in battery life. I guess it depends on what kind of user you are. If you really chew through battery & find yourself reaching for a charger/spare battery halfway through the day, it might be significant/make a real difference to you. If you're someone who charges their phone overnight/uses the phone relatively 'normally', you probably wouldn't notice any great difference, and it might not be worth your while going through the time/hassle of working out exactly how much undervolting your CPU can handle.
Well, I've read some threads on undervolting and I think having a scaling stability test using the StabilityTest app could save quite a lot of hassle to do testing for cases of freezes and SOD. That was what got me thinking about doing some undervolting but not too aggressive to the point that I'm bordering on unstability, thus this thread! :cyclops:

Anyway @andrewwright you mentioned something about Gsam battery monitor, it seems to do the same as betterbatterystats. I have BBS, so that's enough right?
. Its up to you what battery monitor you use :thumbup:. With -25 shouldn't be a problem. Each phone is different. Mine is group 1 which is a bad group to have but I can and am Uv by -50. And all ok

well, its not that 'Undervolting' is useless, but while doing so u have to take some risk, which IMO do always bring about bad results (rather than saving some Juice on ur batt, it might cause instability most of the time ).
So it would be better, the same is left to devloper's of Kernel's since they know what they r doing
This is why I have said little steps first.
I'm not going to say I'm right when a Rc is here saying don't do it but there are risks in pretty much every thing on xda.

But well to each his/her own, there seems to be a healthy bunch of people on this forum that loves their undervolting but yes I agree that to tech noobs like me, maybe we shouldn't mess around so much unless we know for sure what we're doing haha
Thanks for the help everyone! Appreciate it!
