Underclocking - Wing, P4350 General

How far down is it worth going? Right now it is at 110mhz -> 237mhz
If I understand this right it then will run at 110mhz when it is in "standby" mode with the screen blacket out. Do you think i will save much battery doing this?
What is your experience on this topic? (dynamic clocking)

thats what I do, i think I have mine running at 117 on standby

I'm using cpu scaler and I believe that when you turn off the screen it goes to the default clock. It only underclocks when the screen is turned on.
As far as I can tell, at least...

Hum,thats sad! If that is a fact atleast...But after i flashed it to WM6 and scaled it down, the battery-level almost increases over the night If that comes from WM6 or the underclock is hard to say... Guess I could check it out for tomorrow

Hello,
I have a Himalaya (XDA II) with WM2003 1.60.00 WWE.
I use XCPU Scalar and currently have my device running at 200mhz.
So does XCPU Scalar really revert back to normal speeds when the device is turned off VIA Power Button?
I see that XCPU Scalar has an option to turn the screen off, so what is the difference between turning the screen off with XCPU Scalar, and turning the screen off using Power off button?
My goal is to save battery power during standby. So should I turn screen off using XCPU Scalar or turn device off using Power Button?
If I use Screen off function on XCPU Scalar is the proccessor still working but the screen is just off? What about If I use power off button on my device? What is the difference and how will it affect clock speeds and battery life?
Thanks,
kidcash.

Does CPUScaler underclocker save battery life?

I have Battery Status 1.04 beta on my 8125..I set the CPU Scaler to underclock to 112mhz when idle (original is 195mhz). It seems to be doing that, but idle battery life so far doesn't look any better, in fact maybe worse. Is CPUScaler not meant to be used like that?

it does / will / or is supposed to help by slowing down your processor when it isn't actively being used. But 112 seems really low to me. I've heard that some people find their phones won't wake back up when it drops too low (I think 123Mhz is what I've read people use but lower than that caused problems). Personally I set mine to 143 for the min.
If you are running WM6, there just seems to be more power drain. Also depends on what radio you are running (some are better than others) and if you leave WiFI and/or bluetooth turned on all the time.
Also I've read that some apps will cause more power draw due to them running. With BatteryStatus when your phone is idle, does the CPU % go down to 1 - 3%? If so, you should be ok. But if it stays higher, then something is running and that adds to more power draw.
There is also a thread in the Wizard WM6 forum on people finding that playing with the extended rom seems to impact on power draw if you've done a hard reset or similar (they are finding that by going back to an official rom like TMo 2.26 and then reinstalling the custom rom that doesn't have an extended rom the power draw seems to go away).
Hope some of that helps...
Haven't had any missed calls AFAIK, been running it like this for a couple days now. My ROM is Faria's AKU 3.3, which is pretty good might I add.
Idle CPU utilization stays at 1%
The extended ROM theory is interesting, maybe thats whats doing it. My last ROM didn't have anything like that and seemd to have better idle battery life.
If the phone is at idle, what does it matter where it's clocked? When the phone is active, the battery will be drained regardless of clock speed. I have my 8125 set at 192MHz, nd have no problem re-charging the battery.

Average battery life?

So I've had my Touch "enhanced" for a bit over a week and I'm having some annoying issues regarding battery life. I'm charging this thing once at least once a day, twice a day when I'm using it a bunch. I've messed with the power settings, and the phone goes into standby after 2min. The only 3rd party software I have is touchpal, everything else is factory. I was just trying to gauge some input from other users. I did call HTC, and was greeted by an ass of a warranty tech, who, after getting my problem explained to him proceeds to ask me what I want him to do. Wow. Then he tells me that a new battery won't be instock for two weeks! How frustrating!
Thanks in advance.
You should get at least a day even with medium-heavy use. Up to two days on average.
If you install the excellent Chi-Dai Battery status plug-in then that will monitor the power drain on your battery. It will tell you if the problem is software or the battery itself.

Thanks, I was about to download something to moniter the consumption. I'll give it a shot when I get home from school
I have the same issue with my battery. I use it for med-heavy. By the end of the day Im at like 15%. That sux.
I've installed S2U2...does this application drain the battery also?
monitoring your battery life won't do anything when you want to increase it
if you want to save battery life
it's likely that you have your wireless radio's turned on while they don't have to be,
go to your comm manager
WI-Fi drains A LOT of power and should be on only when you plan on using the internet
your GSM phone radio can also be turned off, useful when you're not in an area covered by your carrier when this happens your device panics and sends out signals to connect to the antenna tower this extra cell phone activity is bad for your battery life... and your sperm count
bluetooth takes an insignificant amount of energy to power
lastly pressing the lock button on the device is useful because it turns off the screen but keeps the device on using these features allows me to have my device unplugged for 2 days

2 DAYS UNPLUGGED? Are you kidding me. On standby or using it. Im thinking this battery is horrible. If I dont plug in every night, im in trouble.
If you want to increase the lifetime, use Battery Status software and activate CPU Scaler, it's great!
Before: I used only 201Mhz freq, my battery had a lifetime of 1 day using it normally.
Now: I've overclocked it to 260Mhz with CPU Scaler activated (low: 99Mhz, average: 201, max: 260) and my touch can stay 3 days without charge need.
I still use these settings but I have a unlimited data contract with my operator, so my touch is connected all the time to Edge (push mail and weather updates), and with these settings I have to charge it every day. Don't care about this since I work with a PC all the time.
I think if I used all the time the original freq, I'd have to charge it more often...
CPU scaler
I have Battery Status ver. 0.5 but don't see CPU scaler, is it only available in the Beta version?
1 to 2 days of life with normal-full use. Up to 4-6 days in standby with almost no use

Can you please give me more info on the battery status software and cpu scaler?
Do you have an Elf or Elfin?
I've an Elfin.
Battery Status is a today plugin you can configure and use to overclock and set CPU Scaler.
Here is in attachment the version I use
Overclock and CPU Scaler are only available for OMAP processors, so for Elf/Elfin it will work.

Can you give me some more info about how you have it configured. Most people with Elfin are having problems with this software. It seems to not work for CPU scaler. Any feedback from your experience.
PS- I have the HTC Touch enhanced unlocked.

I turn off the wi-fi when I'm not at home. I'm always within service area, so the GSM radio stays. I don't use bluetooth. It's set to go into standby mode after 2mins. On Thursday, I took it off of the charger at 8:30am had a couple classes till 3pm, so light-to-medium use. It was dead by 3:30pm. I did install BatteryStatus later that night, and figured out the scaler, and it helped the next day. But honestly I shouldn't have to underclock it in order for it to last even a day, a bit ridiculous to me.

I have a Touch enhanced, and am using the CPU scaler just dandy. Just play with the settings a bit, and you'll get the hang of it. Try LOW:100 and HIGH:234, to start out, then go from there.

Visit the Kaiser forum. We're having the same issue. GPS seems to be the problem with me. As soon as I turned on GPS, it sucked my battery 5% in 5-7 minutes. Then down to 73% from 97% in 3 hours.

I didn't configure anything particular, just installed it and set the overclock and CPU Scaler.
I talk an average of 2 hours daily. Since 6 am until 8 pm. I always get home with 15% or less. Using batt status with omap overclocking to 247. Average use of pda also.

Right on brotha. It worked great! I was wondering whats the lowest low you can use to conserve battery? Im at 98-low 247-high, using CPU scaler.

Im on 87/201/247 and boost to 260MHz, everything works fine, only some flickering when it runs on 87MHz..
But the battery life is quite good as it lasts for 2 to 3 days (light to medium usage, some texts, some phone calls, seldom Wifi)..
I have to say that the stock battery lasts much less then the one I got from Brando.. although the amperage is the same
I finally use xcpuscalar only for conserving battery, not for overclock. In another threads some people suffering from spotted, patched even broken LCDs and I do not take the risk to overclock Elfin because of possible overheat of the CPU and the CPU is most likely very close to the LCD due to the thinness of the Elfin. If the CPU is hotter overclocked than it is on normal speed it could cause spot, patch or even damage on LCD. This is my opinion.
Xcpuscalar is able to downgrade dynamically the CPU speed against Batterystatus which is only able to set one speed for the CPU, that's why I chosen xcpuscalar.
It seems to work fine even after soft reset... but 87MHz is very slow for me... it speeds up very sluggish. I use 169, 182 and 195MHz settings.
Will see the energy spare on the battery.

Reducing processor frequency - to save power

Hi guys,
If I remember correctly, in the previous WM versions there were options to change the speed of the CPU and that way to save the power and reduce battery consumption?
I am preparing for long, few days GPS assisted hikings and would like to minize the power comsuption of my HTC HD2.
Maybe there good apps for that too?
Thanks.
It already does that automatically.
Consumption of a GPS app like GPS Tuner with screen off is already very low, giving about 8hrs battery life (if you don't do anything else, of course).

Some tecnical question on N1

Hi guys,
i've my Nexus from about a week. My battery life is about 24hr but I use phone with Push mail (activesync with TouchDown). I don't know if I can boost battery life with a custom kernel UV.
I want to know if in sleep mode, the Snapdragon is fixed at 1Ghz? Or only with a custom kernel it goes down to 245mhz? Can this give me more battery life?
Thanks!
the phone idles at 245 mhz in all roms, not just modified ones. otherwise the phone would only live for 2 hours, tops, before the battery runs out.
in sleep as in "pc like standby" the cpu turns itself nearly off. from time to time it will wake up (timer based, interrupt) to do something, without turning the screen on. depending on load it will set the cpu clock accordingly. (generally it should be on less then 1% of the time)
you can actualy see this quite nice when you open an ssh session to the phone and switch it "off". every input in the session now takes ages to complete, because the phone aggressivly tries to sleep.
Your biggest power drain is going to be the screen. Try turning your brightness down, or if you haven't already, enable the auto brightness. I found this saved me a lot of power.

Does power saving mode really save juice?

The way that I understand power saving mode is that it saves juice by changing backlight based on what is on the screen. However in order to do this it.means cpu would be constantly used. So does power saving mode really save juice? Is the amount of battery saved by changing backlight more than the battery used by constant cpu usage?
That's a good question but I highly doubt that they would add the feature if they didn't test that it actually saved power. But, stranger things have happened.

I assume you aren't basing that statement on recent events of failed quality control on high-end phones
No, it does not.

And this is based on???
From what I have read, having power saving mode on is another process the cpu has to worry about therefore possibly causing more battery drain. Personally I have disabled power saving mode and auto brightness and have experienced a slight improvement in battery life. I use the slide on taskbar feature to adjust brightness manually.
I have both Power Saving Mode and Automatic Brightness on, 3G off, and I get over 40 hours in normal use! I hope that tells you these settings don't drain the battery and you shouldn't worry about having them turned on.
It is NOT putting an undue burden on the cpu, and small amounts of CPU usage have MUCH less effect than powering the screen.

I have to ask what is normal use for you? Cant imagine getting 40 hrs on any device besides a BBerry.
Sent from my SGH-T959 using XDA App
I find that the 'auto settings' takes away from a session - screen dimming and back again. Swipe to adjust brightness seems to work fine. As far as I'm concerned, the Vibrant is running normal when usage puts Screen at 83% or so.. After all, we bought it for the display to begin with

They released the phone without doing adaquate testing on the GPS.
HTC released the G2 without turning it upside down & seeing the hinge go a flyin.
Just because they threw a feature in doesn't mean that it's been tested.
We're the testers

He keeps is 3G off, thats what's saving the battery. That and he probably was sleeping for 16+ of those 40 hours.
Just an FYI, I have been running my phone on automatic brightness + power saving mode for the past few days as opposed to my usual lowest brightness + no power saving mode; and usually I would get inbetween 3.5-4 hours of screen time (depending on what I did) but now I am getting 4-4.5 hours (same usage). Obviously the automatic brightness does not improve battery life over lowest brightness all the time, so power saving mode must be doing something right -- something aside from just lowering screen brightness as needed.
That is a feature of 2.1 that is intended to help people with LED backlit screens by turning off LEDs in areas that are black. We have SAMOLEDS, which are lit by pixel, and we get battery battery life by using black themes. That is why Fusion 1.1 is nearly all black, and gets insane battery life.

Actually, that doesn't tell us anything. What is your battery life like with Power Saving and Auto Brightness off?
