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.
About a month ago, I was running RoyalGinger 3.0 with bluetooth, GPS, and background data disabled, and I was only using my home wifi to get online. My phone would pretty much hold a 100% charge for 5-8 hours if I left the screen off. I was pretty amazed at my battery life. Then I decided I wanted to try a different rom, so I backed up in CWM and did that. When I returned to RoyalGinger, my phone wasn't holding the 100% charge for as long anymore and hasn't done it since then (yes, I did re-calibrate the battery, like twice at least).
Recently though, my phone has been having horrible battery life under the same conditions. The only difference is that now I use LauncherPro instead of the stock launcher. I'll charge to 100% + 15 minutes or so, and with the screen off, the phone divebombs to about 95% within an hour and a half. If I actually use the phone, it will lose 30% in 2 hours. I have no idea what the problem could be since I don't have any data-syncing apps in the background and I'm really just texting people.
Any ideas?
The consumption doesn't sound like anything out of normal. A difference in signal quality (radio or WiFi) or using radio for data instead of WiFi can cause that.
In any case, just check the apps that use your battery, and see that you don't have any process getting CPU stuck on 100% (you can see CPU load in System Panel Lite, for example).
Download the apps below.....this will help you out.....
Use the app SetCPU for Root Users
It allows control of certain aspects of the Linux cpu freq driver, allowing for overclocking, underclocking, or tweaking speeds and settings. Download it here.
Use the app Battery Booster
Battery Booster is a powerful battery boosting tool and power management application specially designed for Android devices. Download it here.
Always remember to remove the charger immediately when the battery level reach 100% for longer battery life.
Disclaimer; This does not damage your phone at all or fry/mess your cpu.
This method is used to lower CPU stress and increase Battery life
This method works for all rooted phones.
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%.
LINK
Deep Sleep breaks when charger is plugged in, you can see this by CPU SPY application available on playstore
Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:
Also Turn BLN off when you are sleeping.(It also Consumes battery and sometimes prevent deep sleep of CPU)
Set your Brightness to minimum and disable auto brightness.
LINK to Display Brightness
Instead use lite app called - Display Brightness from play store.
Turn off wifi and mobile data when not in use.
Use toggle for auto rotation, and keep off when not needed.
For more battery Saving, disable all animations and set screen timeout to 1min.
The S plus sucks in battery life. We all know that.But here's a fix, Try Under clocking instead of Over clocking.
When screen is on:
MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)
MIN 192Mhz
Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 365 Mhz
MIN 192 MHz
(This prevents lagging when playing music and other activities when screen off)
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!
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.
SetCPU:LINK
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 and I/O schedulers detailed;

To check if its all working, install CPU spy from the playstore: LINK
For Playing GAMES(HD)/HEAVY GAMES, Plug your Charger in and play if possible.:good:
Most Important thing is to calibrate battery,
Calibration of battery is needed when you change your ROM.
This process wipes batterystats.
Battery Calibration
1. Charge 100%(NON STOP)
2. Download any battery Calibration tool from play store; (Link to App)
3. Open that app, click battery calibrate
6. Unplug your charger
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. No matter how much you try to optimize battery by tweaking and underclock, if you have 3G on, you're gonna have a bad battery drain.
Make sure that Autosync is disabled.
Done A small test usage 14 mins , you can see in attachment your CPU should look like this.
THIS READINGS FROM MY SGA.
And never ever install the Facebook App if you want to use your phone for more than 3 hours!
Sent from my GT-I9001 using xda app-developers app
Don't get apps that take background processes like what xellar said, facebook, and some other apps like tap tap revenge 4. Anyways thanks for the tips and link to free setcpu
Other people can also share VALID ideas about saving battery.
Will help many users.
Nice advises. I'm already using these.
One more good thing is turning mobile data off whenever you are not using it, also bluetooth, lowering brightness.
Good app for doing so is Power Toggles. You can always have widget on home screen and switch on/of these things with one tap.
Riiight.. Turn off autosync, disable 3G and wi-fi, dont use apps or games.. I might as well buy Nokia 3310..my phone lasts easily whole day with wifi on..with 3G it can get me at least 6-9h which is fine.. The key is to turn off 3G when you are on wifi and turn down brightness.. Everything else is not using your smartphone smart..
1) Set your network mode to 2G only if you're not using 3G/WCDMA
2) Manually set your operator in settings.
PS: After flashing one of firmwares I got a bug - battery is not charging to 100% while phone is ON. Only to 99% and not showing a message about fully charged battery... But when the phone is in off mode - it charges to 100%. Anyone knows how to fix this thing?

Take a other kernel with better voltage and governor configuration.
Set Display time to 30sec.
Kind regards.

On Amoled-Displays it should help. Inverted Apps, too.
setCPU
i testet the new version of setCPU 3.0.9, deep sleep works perfectly.
If profiles are not used it exits and there is no use of RAM in both versions (But then you do not have the unique feature of auto switching profiles ).
Is there another app with auto-switching?

Actually no idea.
But other simple and best app for controlling CPU is NoFrills.

But it has no profile-autoswitching, in fact no profiles at all. Voltage control Extreme has at least profiles, but without autoswitching. What is good about Voltage Control Lite/Extreme is that it sets cpu setting with init.d and so the app does not have to start on boot
Yes that is nice...

Many thanks for the battery saving hints. I'll finally kick out the Task Killer App, doesn't really seem to do anything except creating problems ..
For the statement that Underclocking would help in saving battery I wouldn't fully agree. A slow cpu needs more time to complete a task before returning to a sleep state. Of course the battery drain is higher with a higher frequency (which also require higher voltages), but I believe, that there isn't much to gain on this front. As long as I don't see any profound evidence I'd even suspect, that an underlocked CPU overall could even cause more power consumption. You can also read more opinions about this in general in this thread.
Much more beneficial would be to identify those apps that cause frequent wakelocks. Does anybody have hints here, how to track down those 'bastards' ? (From my Linux I know 'powertop', does something similar exist for Android? (Or are the battery statistics in CM10 sufficient to decide which app to wipe?)

Better battery stats is application useful for identifying partial wakelocks.
Its an paid app, but Google helps... Lol
Your above sentence about UC comes true for heavy usage.
Normal apps can run smoothly and at same speed as of OC.
I'm searching for the perfect gaming rom
For me a gaming rom need to have good performance and great battery life.
I tried a lot of rom but didn't find the perfect one.
Please share your experience (rom, kernel, settings) which make you stay with.
Well, I'm using the GPE rom by Danvdh. I'm running the default kernel that comes with the rom (Googy-Max kernel)
It seems to perform pretty well.
I underclocked the CPU to 1242 (1.2 GHz) and it seems to be running GTA San Andreas (on default settings) and The Walking Dead just fine and without any issues like stuttering and slowdowns.
I could get about 2 hours playing those games on battery before the battery dies (But the phone is only a couple of moths old, so the battery isn't worn out). This of course is just an assumption as I generally don't let the phone go below 50% or 20%.
I've disabled the button backlight and vibrations. Set the screen brightness to the lowest setting (adaptive brightness off). Turned off GPS.
Turn off wifi and mobile networks if you want maximum battery while gaming (duh). Heck, you might as well turn off the radio if you want to maximize battery while gaming, (put it in airplane mode) cuz that eats the most juice (aside from the screen).
CPU Governor: Intelliactive
I/O Scheduler: FIOPS
GPU Governor: OnDemand
Every other option in the STweaks app is set to default.
Also, make sure there are only a few background apps running.
So I got my official stock ROM rooted using the guide pinned in the forums (How to Root etc etc Keep your DRM Keys etc) I'm on 5.1.1 546.
And I get great battery life when enabling Stamina Mode.
What happens to Stamina Mode if I decide to use customized ROMs and/or Kernels that are tweaked for "better battery life" etc?
Also, what about undervolting manually using Kernel Adiutor?
Will any of this impact or degrade Stamina Mode? Or does Stamina Mode get useless when manually tweaking kernels and undervolting? Or, will it cause Stamina Mode to malfunction or crash?
I am considering unlocking the BL to get even better battery life somehow. Is this advisable? Or even possible?
:silly:
Stamina basically avoid network usage by apps that are not whitelisted when the phone is locked. You can still improve battery life using other methods.
No, there is more to it than that. There's two separate toggles to enable under Stamina Mode. The one you mentioned is Extended Standby, it only adjusts data flow during idle time. I do not use it at all because I do use background data a lot.
There's another toggle for Stamina Mode called Extended Usage. It's description reads "Restricts device performance to increase battery time". So it probably underclocks / undervolts the cpu and /or gpu. Probably. And if that is the case, underclocking and undervolting via an unlocked kernel would probably either mess it up or make no difference.
Does anyone know anything about this?

Thank you for your reply. Yes I followed that exact same guide to root keeping DRM keys. And I had installed Kernel Adiutor but I had not underclocked yet. Now I disabled MPDecision, set CPU max to 1574 and governor to Ondemand. Hopefully it will help save a bit more battery.
