Has anybody with a Note 2 tried the One Power Guard? I'm rooted running Scott's Clean ROM Verizon Special Edition, with the kernel that comes with the ROM. While I have had no issues with my battery, I figure it's always better to use less battery, right?
Questions for users: does the phone seem to run any slower? Are there any lag issues? Do you switch modes frequently or does the AI mode seem to do the job well? Since this app seems to base most of it's settings off the min and max frequency, are there any settings in my ROM I should change relating the processor frequency before installing? Would it be more effective than just using the "Power Save Mode" that Samsung has included?

Don't worry about your phone lag.
3 way can make it run well.
1. Change other IO until it is the best
2. Make higher CPU frequencies.
3. Change other CPU governors such as: "powersave" more lag than "ondemand"
so try to change some settings until your phone run the best.

I'm now on Criskelo the great ROM, having good battery but I wanna squeeze it even more (ie. save more juice!)
Then I found One Power Guard yesterday, and installed it. Running on default (AI mode), I notice it's draining battery even more so, I wonder why?
Anyone notice this issue?

its a paid app so therefore i will not post any links. but there is some info about using it on the galaxy s devices and how we should avoid some settings and use others to dodge the bugs...
copy/pasted
Description:
SetCPU is a tool for changing the CPU settings (capable of overclock and underclock) on a rooted Motorola Droid, Nexus One, G1, G2, Samsung Galaxy S, or one of many other devices to improve performance or save battery.
SetCPU also allows you to set up profiles to change the CPU speed under certain conditions, such as when the phone is asleep or charging, when the battery level drops below a certain point, or when the phone's temperature is too high. See the screenshots for examples of how you might set up profiles.
SetCPU's wide feature set make it useful to beginners and enthusiasts alike. Accelerate your processor to unleash your phone's multitasking potential, or dial your CPU's speed down to save battery.
Have an HTC Sense device with a stock ROM or kernel? If you are having trouble getting your settings to "stick," press Menu > Disable Perflock. You still have to be rooted.
Galaxy S devices: ondemand scaling is recommended. There are issues with Galaxy S kernels that may result in crashes if conservative scaling governor is used, or if the sleep profile "max" value is set too low. Please do not set the sleep profile too low, and avoid using conservative scaling.
Requirements:
all Android versions
Recent changes:
2.1.0
- Significant UI and user experience revamp, including a new background for the widget, and new notification icons
- Added a quick priority swap button to the profile lists
- Significantly improved the reliability of autodetect on certain kernels
- Numerous bug fixes and crash fixes

I understand it's a paid app in the market. But if you're an XDA member you just go here:
http://forum.xda-developers.com/showthread.php?t=505419
It's not a secret...
Funny, the previous version of SetCPU specifically told Galaxy S users to use conservative scaling and that ondemand would cause crashes.
Now they're saying the reverse.
Edit: Well, I switched it to ondemand as the app dev suggested and the phone turned itself off a few minutes later...
Are we suppose to flash it thru cwr?
Edit: nm I got it.

Do you have a profile for screen turn off? If you do disable it because the phone itself lowers the cpu while at sleep.

I have no profiles set. I tried doing the sleep profile but it caused some annoying lag when the phone was waking from sleep.
On demand profile settings do not work, my phone has crashed 2 times. SetCpu just doesn't work I guess.
Using Nero V 3 and set CPU isn't doing anything...max setting is set to 1000.
How did you guys get it to work and what are your settings?
Sent from my Galaxy S via XDA App
Those of us using SetCPU are using overclocking kernels. Some folks might be using DOW, but I am using JAC XMOD because I'm still on Eclair as all the 2.2 ROMs annoy me currently.
(At least until I get my Bionix Blackout for Nero v3 theme finished!)
Hi guys!
I've noticed recently a new power save get option in the power saving menu in settings called 'system power saving'.
I've never seen much point in using the specific power saving mode that you can set to kick in at x% because it doesn't seem to do anything I can't and don't do manually myself.
Does anyone know anything about this new setting? Turning it on i've noticed screen transitions are a little less smooth, but does this actually do anything useful?
Any ideas?
Many thanks!

I would be interested in finding out what this does as well.
I noticed that frame rates seemed lower in games, and the responsiveness is a little slower (not considerably, though).
Is there a list of what it actually does?
I've notice that my phone uses less battery in this mode that without it.

Well, I would hope so...
I do know that it does NOT disable background data (I still receive push emails with both Exchange and Gmail)
Camera and Auto-flash are still enabled.
Everything that typically gets turned off in order to save battery is still on as far as I can tell...
We know it saves battery... but how?
If we find out how, then our developers could probably leverage that information when making new ROMs.
I would just like to know if anything is being disabled that I don't want disabled... but I don't know what I don't know
It lowers the CPU clock frequency, in my SGSII, scrolling desktops is not smooth at all with this option ON I've never been patient enough to test this option for a long time
when i activate powersaving it doesnt seem to make a difference

Seriously?
I have mine overclocked to 1.6 GHz and the conservative governor and I have not noticed the time-in-state data to be changing from what it was without this option set.
You were right about the clock speed.
system power save does the following:
Restricts core speed (mine was capped at 800)
Lowers brightness
Changes UI frame rate

So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.
Update your firmware

I am rooted, thank you for the info! I'll be looking into it~
Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.

There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.
Hi to all, currently on N910C Stock Sammy Marshmallow 6.0.1, as much as I hate it (the theme, colours, bloatwares), one thing I appreciate it comes with is that, it is for sure stable, and it comes with permission setting (like finally.)
I can deal with all these themes bloatwares easily, am rooted anyway, but one thing annoy me a lot is that the power saving options. We are no longer able to control what we can in previous version (i.e. select only screen output and limit CPU usage), now it restrict background activity as soon as I activate power saving mode. I need that to be disable as I know that my emails won't sync automatically if I had it switched on, and email is quite important for me as for now.
So, I need alternatives. I hope to get some suggestions for application that can do power saving for me, or control my cpu frequency, like underclock. I've tried a few set cpu app, they all doesnt stay at the setting I put. Meaning I put my MHz to 1200, it later went back to 1900MHz again after awhile. So i need a really good recommendation, as long as I can push my battery life to maximum.
*P.S., make sure it is user friendly, I am not familiar with coding/technical stuff myself.
Thanks in advance,
Anyone can help me with this one?

BACKGROUND:
That's right, a wall clock, in the kitchen.
You see, my old i9100 has been laying in my drawer doing nothing for years.
Inspired by a post on the internet called "18 things to do with your old phone" or something like that, I figured I want to use mine as a kitchen device.
Mostly as a timer when cooking, and maybe as a wall clock (I have a conviniently shaped picture frame on the wall in the kitchen that can hold it). No other uses, so my use is exremly lightweigt.
Since I only cook thrice a week, the phone will be used very seldom.
I am therefore looking for how I can set up my phone for lowest possible battery consumption.
Note that I have taken out the SIM-card so I will not be connected to any carriers.
I figure I need a:
-low power kernel, like dorimanx or siyah
-a ROM that is as bloat free as possible, and barely does anything in the background
QUESTIONS:
-Will keeping the phone in flight mode reduce battery consumption?
-Do you know any ROMs that are as bloat free as possible, and barely does anything in the background?
-Does the Android version (JB, KK, MM, LP) matter in regard to power consumption?
-Should I avoid flashing gapps, do they consume power? (since I won't be using them)
-Any other tips to reduce battery consumption?
Maybe flash CyanogenMod without a Gapps package. Gapps are eating a lot of power, for example Google Play services, which keep running in the background.
Chose an old build, for example CyanogenMod 10.1. Deactivate all unneeded apps via settings. Disable searching for WiFi networks in advanced WiFi settings. Disable GPS, Bluetooth and WiFi. Aeroplane mode is also worth a try.
Just a few ideas. I hope this helps somehow.

Find a kernel that allows for undervolting then set the CPU to its lowest setting, you won't need a lot of processor power because what you use it for is not intensive.
