Default [Hint/Tip]Best way to save battery [UPDATED 10.12.2012]

Disclaimer; This does not damage your phone at all or fry/mess up your cpu. On the contrary, it helps it by not running at full capacity all the time resulting in less stress and increased battery.

This method works universally for any Android phone you're using. But you'll need ROOT for Set CPU.

IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.

http://forum.xda-developers.com/showthread.php?t=505419

The Ace sucks in battery life. We all know that. And on 3G? Don't even mention it. But here's a fix, ever tried Under clocking instead of Over clocking?

Someone brought it up on a thread a couple of days ago and I have to spread the word, that works wonders. Got my Ace running on 245 min and 806 max and a different Screen Off profile. And now from the morning till 6PM in the afternoon, its just 61% AND recorded a 7 minute video/took pictures.

Battery was the only issue I had with my Ace. But now that its fixed, I love it

When screen is on:

MAX 806
MIN 245
Ondemand governor
(This governor bumps up to max when needed but spends most time on the min freq. Best battery saver.)

When screen is off:

MAX 320
MIN 122



This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!

This is what CPU spy should look like when you're done:



NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do. 3G is the worst battery killer so this will help a lot.

SetCPU: http://forum.xda-developers.com/showthread.php?t=505419

Specific instructions for those that can't get it to work!:
On SetCPU:
Click Add profile
Where it says Profile, select it and tap "Screen Off"
Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)
Set priority (in case you have other profiles, otherwise don't bother)
Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)
Tap save
Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.

For a list of most governors detailed; check out this thread! http://forum.xda-developers.com/show....php?t=1242323

To check if its all working, install CPU spy from the market:

Battery Calibration

1. Turn your phone off
2. Leave charging over night
3. Turn it on
4. Leave it charging for half an hour
5. Download this app https://play.google.com/store/apps/d...=search_result
6. Open it and press calibrate battery
7. Discharge your phone down to 0% during the day
8. Charge back up to 100% NON-STOP.

This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.

The worst battery killer is 3G itself. No matter how much you try to optimize battery and underclock, if you have 3G on, you're gonna have a bad time. MAKE SURE Autosync is disabled.

Thanks to QNBT for the AutoSync off and new profile settings hint!

Hey dude I may try that tip, but I wanted to know about the governor that you are using, is that one a battery saver?, and what about chainfire 3d? you said that you dont use heavy apps and as far as I know that one is for heavy gaming isnt it?

ps. I recommend you install Vturbo 8.5 by gadgetcheck since I didnt see it on your signature, it really works

Yeah, I'm not using heavy apps now but I do like some gaming now and then. When I do game, I crank up the processor back to normal but I rarely do. And I use Smartass governor, not really sure if its a battery saver but its working great.

And yeah, I think I had turbo 8.5. But for now, my ace runs perfectly fine so I don't really need other scripts or optimizers :P

CPU governors control exactly how the CPU scales between your “max” and “min” set frequencies. Most kernels have “ondemand” and “performance.” The availability

ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.

interactive – Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.

conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.

performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.

powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.

userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.

smartass – Included in some custom kernels. The smartass governor effectively gives the phone an automatic Screen Off profile, keeping speeds at a minimum when the phone is idle.

Thanks for the tip, works for me

I have no idea. My phone's working fine. I keep switching between interactive and smartass. Can't really tell which one works better xD

Haha good to know it doesn't only work for me. I clocked it down lower to 320 since I'm barely using it now. Love my ace
