Improving your battery length - HTC Rezound

I discovered something that drastically improved my battery performance even with it sync on all day. If your rooted get the CPU master pro app, and under profiles enable the screen off profile and set the max cpu freq to 918, or lower if you want your battery to be better, i found that 918 keeps me charged all day though, it will depend on how much you use your phone cause you'll only be saving battery when its not in use, if you use your phone alot then just go to the main profile and set it to around 1200mhz
Edit: I'm using RezRom1.6

Thanks for trying to help others but this belongs in the general thread or apps one.

and im pretty sure just about anyone who has been here more than a few months already know this

Thanks for the tip. But I have to agree with everyone above me.
Also..
The title of the post made me think you were making your battery longer... I was like "why on earth would you try to do that???"

It's something cool, you could use SetCPU or Overclock Widget, and it's like adding rocket-fuel to a campfire.

the time it took you to be a smart ass you could have just said what it did.
i did a search for it and yet it wasnt informative enough. hence why i came here and asked.
Google want enough? Wow! Over clocking increases the clock speed of your cpu making it calculate faster.

Alright, then I'm sorry Google couldn't answer your question. (Which is odd, since overclocking is kinda popular.)
Anyways, Overclocking means to "Make the CPU go faster than it was designed for". Some devices "like the hero" can jump from 518mhz to a stable 691mhz by overclocking, this increases the speed of the CPU so that programs and the OS can work faster.
But overclocking is about finding the highest speed, while having the stability to use it. Since it's no use to overclock, if it makes your phone unusable to use. (Force closes, phone freezing etc.)
Overclocking CAN harm your device, if you take a too high value. But if you stay inside a stable zone, there shouldn't be any harm to your device.
You can experience that the phone is getting a bit hot, or that the battery is emptied faster than normal.
Since the CPU drains so much power, there are settings that allow to set a different clock (how fast the device should go in mhz) when the phone is at sleep. So that it can run at a much lower frequency, when you don't use it.
ROM developers normally post ( 691/197 ) or something at their thread, the first number is the CPU speed when it's on and you're using it. And the other is when the phone is at sleep.
If there's anything other you want the answer to, ask it here.
But, please use Gooogle search Before posting anything.
Overclocking increases the clock speeds of a CPU. And as a result means it can do *things* faster.
Overclocking on a desktop PC tends to increase the voltages to overclock the device over this isn't really an option on a phone as it has limited battery life. So overclocking on a phone is normally done by software changes. When CPU makers make a CPU they can not be 100% accurate on the performance of that chip - in fact its very much the opposite, so after each chip is made it is tested and then given a clock speed and locked to that, overclocking breaks that and allows you to manually increase the clock, however overclocking capabilities will be different on every device.
If you take an example of an Intel Chip, a 2.66GHz Core-2-Duo, this is exactly the same chip as the 3.06GHz however when tested it wouldn't run as fast so Intel sell it at a stable clock speed.
Overclocking the hero shouldn't really have any implications for the device, however overclocks can reduce the life-time of a CPU (and any other hardware you might overclock). You shouldn't notice much extra heat from the device as the voltages being used are not changing.
Hope that cleared some of it up for you.

Best Overclock App?

What is the best overclock app for a rooted Eris running Froyo 2.2?
What is the best min/max setting too for performance?
I use SetCPU. It really depends on what you want.
I want the best performance possible, without overheating my phone
No matter what you're going to heat up when overclocking. If you use setcpu don't use the widget.
What's the safest maximum performance setting then?
What about overclock widget app (free)? I'm using that now. It seems ok, not sure though compared to setcpu.

that widget app sucks. it's nothing compared to setcpu. I run 768max 19 min, and I have a full day of battery life, using it fairly regularly every day. I rarely have lag, and it's fast too.
using kayosfroyo btw.
Every processor is different. Some people get get to 844mhz, some people can't push past 710mhz. You need to find what's right for you.
I personally get up to 787mhz.
I run 806 all day no problem. But faster is a reboot. All phones seem to be different on their safe max w/o crash. I use setcpu myself. It's free on this fourm for members.
Sent from my Cyno Tazz 3.0 using XDA App
Yes, SetCPU is best. I can clock mine to about 806 and I get about 48 hours of battery... every phone is not the same, remember that!
using setcpu here as well. 825mhz no issues
Im using set cpu as well at 768 max and 245 min. Make sure u dont have set on boot if ur going to test the limit of ur phone, I did and was able to go 806 and past rat my phone locks up and on every reboot the same so I had to uninstall in using command prmpt from pc

This is the place i liked the best only because i needed increse speed with out loosing to much battery power due to not being in a place to set phone on the charger like i work 9 hours a day and i like to listen to music and fiddle on my phone on breaks.. Plus honestly my phone does not seem to be performing any slower than it was with a high performence setup i used to be 480 min with a 787 max, and somtimes higher but 245 min with 748 or 19 min with 748 i still have not noticed anything being slower than when i had it set at 480 min 787 max..
But i cant stress enough that dont have it set on boot when u are trying to find ur phones limits because if u do have it set and find ur phones limits u will have to adb that crap to uninstall it. find the settings u want for your phone before you set on boot
Edit: And i have also been seing people post that after testing they have not found there Eris being any faster than 710 just that higher decreses there battery life. Which is Maybe why kaosfroyo has it alrdy clocked at 710 but i dont know, you cant quote me on that.. I hope i was of some help

Overlocking with smartass

Hei guys, I'm really, really new to this.
I've just flash andy's port of CM7 based on 2.3.4. I'm having a really though time with the battery, it goes down 50% faster than on my previous 2.2.2 official Froyo from LG.
Anyway, this question is about overclocking.
So, inside CM7 settings there's this "Performance" menu, in which you can go to "CPU", I've set there smartass governor, minimum 122 and maximum 768.
What does that mean? Does that mean I'm overclocking my CPU? Does it mean that smartass will allow or push the CPU to 768 when it's needed? Do I need to do something else in order to achieve that? (i.e - use get the CPU at 122 while screen off and increase it according to demand up to 768). - that's what I'm after.
Any response on the topic(s) much appreciated.
Thanks.
Regarding battery - calibrate it with the app from the market
Regarding OC - yes, when you'll use the phone your cpu will run at 768 mhz (note that you might get kernel panics). Your minimum speed is pretty low and it will take a little longer to get to 768... you will see some skips or lags.
Oh, and yes! You're overclocking and smartass will do what you're looking for (idle-122/in-use-768).

I would kick the min up to 480. That usually gives you a good balance.
Sent from my LG-P500 using XDA App
Thanks for the fast response.
As for the battery, I tried calibrating it and still the same.
I'm reporting 10% (exactly) each 2 hours, in idle, screen off, everything turned off except mobile data on EDGE.
At this rate, the phone goes dry in exactly 20 hours with minimal to no use. This isn't normal.
It heats up when charging (more than usual).
In battery stats I have all the four ones (android system, cell, etc.) at 25%.
No apps installed.
Just a few hours ago I tried replacing the stock kernel of andy's with the latest from franco (16) and zram.
Exactly the same.
I don't know what else to do, I already reflashed it twice. Same results. I can't post to the development forum just yet (not enough posts).
I guess I'll just go ahead and try mik's port... although I wouldn't want to, I love this one, everything works perfectly except the battery thing.
Did you use google maps?
"Known bugs
[...]
- Google Maps is eating your battery, kill this app after using in Setting->applications
[...]"
i think smartass does automatically change your cpu's frequency when you need it..but your minimum frequency is too low..change it to 320 Mhz....and are you using 3g all time..??
Yes, used google maps but killed it. Second reflash didn't even install it and still the same problem.
No, I didn't use 3g at all.
I only kept mobile data active on EDGE. and as I said, it was in idle. it's like the phone was used 24/7 even in idle.
and why is my cpu to low? the phone works like a charm with that frequency.
Check the 2 g networks only box in settings-networks- mobile networks....that may be the reason
Sent from my LG-P500 using XDA App
It's checked alright. Like I said, I used it on the EDGE (2G) networks.
Anyway this doesn't matter anymore since I've switched to mik's rom.
you can give void# forever a try too...gives me two days battery life on moderate use...
Okay, I will.

Undervolting and profiles. And xda not pushing notifications

Undervolting and profiles.
I have tried a crap ton of different undervolting setting, but none work
Also the profiles in set cpu don't seem to work for me. I have a few of them set and it always sits on the top one I need some guidence with both please!
Another thing my xda premium app isn't pushing my notafications yes its set
Sent from my MB860 using xda premium
Undervolting is a delicate process. It takes time to find the max undervolt that is stable. With that being said, try undervolting everything by the lowest amount which is -25mv. Check to see if that is stable. If so proceed to go further. Remember lower freq will typically undervolt farther than higher frequencies.
As far as profiles go your probably not using the priority values right. The higher priority is what determines which profile setcpu uses. So for instance if you want a safeguard against overheating, you could set the profile for when the cpu goes above 55C to throttle the processor way down. If you set this profile to 100(max) it will overide all other profiles at 98, 99, 75, 50...etc. Also this may be obvious to some but be sure to tick(enable) the profiles button. If thats not ticked then it doesnt matter how many profiles you have set up. It simply wont use them.

Sent from my MB860 using xda premium
Glad your getting some results. If it restarts even once it means at least one of your undervolted freq isn't stable. With your settings I would wager its in the uper freq considering your undervolt in the lower freq isn't too extreme. You might try decreasing the undervolt for your upper freq to -50 -50 -50 starting at the top. Might help to stabilize bc higher freq just require more voltage. If that proves to be stable continue trying to reduce the lower freq as much as possible. Mainly bc if you set your profiles right(screen off is the most important really) your phone will spend the majority of its time on the 200mhz freq. Thus the more undervolt on that freq should theoretically give the most benefit from undervolting. This is just all from personal experience. I'm no guru. Just spent way too much time adjusting voltages on phones . And of course having the upper freq undervolted as much as possible cant hurt either.

First off, regarding SetCpu and over / undercloking, dev has said it'll only underclock/overclock ONE core at a time. It's a bug and he's working on it from what I understand. If both cores are needed to be in use at the same time, no over / underclocking will be applied. Secondly, profiles work as they should in SetCpu, so that's a problem on your end. Third, the undervolting can't be more than 100mv differnce between jumps. See screen shot.

Yea Im skeptical about not setcpu not having support for dual cores... Did some searching on the net and couldnt find anything to support that. As far as not the tegra 2 not being able to do over 100mv jumps. That's not true. My lowest frequency is 600mv (-150) and my next frequency is at 750mv. That's a 150mv difference right there... And I'm completely stable. Its entirely dependent on your processor. They are all different and respond differently to undervolting. You just have to find what works for you. Generally though the lesser the jumps in voltage will give you more stability.
a good kernal helps too im useing faux123 v2.0 0C1.3 its undervolts quite well

how and why to overclock (toms hardware article

Opinions from people who really know? I can't imagine that overclocking increases battery life.
It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

doesn't the increase in voltage also come into effect?
They did talk a little about undervolting to increase battery life. Personally I don't worry about it. I'm not using my phone to sort out heavy algorithims at the moment, so running how it does is fast enough for what I use it at. Just found the article interesting.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.
Why to overclock and understand it?
Here is a good reason to know what you are doing..
and the battery avg's lasting at least through the day, but most of the time, I have a charger near me...

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
