Hi guys!
What can I do to get better battery life?
I'm now using devoid #froyo-final, franko kernet 19.4 and SetCPU (480-691 smartass, screen-off: 320-320 smartass). What am I doing wrong?
What are the best profiles for SetCPU? What do you guys use for "screen off"?
What is the best ROM + kernel to use.
I used mik's CM port, but it drains battery kinda fast.
I don't want to have a battery that lasts one week, I just want 48 hours with moderate using.
How can I do this?
Thanks!
Use 480/729 MHz and 480/480 use with the screen off with the kernel minmax 19.4 franco

Dont use screen off profile,it causes wakelocks and reduces battery when idle.

Firstly, when you're using smartass, there is no need to set a sleep profile. Smartass, by default, sleeps at a lower frequency than the max frequency. Just set min and max freq and leave it as is. No profiles needed. The profiler app itself may consume resources scanning for CPU usage.
If you want best battery life, go for Mik's 6.5.7 with the latest franco's kernel/fserve's version of franco's kernel. Do a clean install, clear your battery stats, etc (I assume that you know the drill). Manage your apps and the auto-syncing feature properly and you'll have good battery life for sure. And, pls give some time for the ROM and kernel to get accustomed to your phone. You'll get good battery life gradually.
Good luck
yes do what gkarthik16 said you can also use v6supercharger script
don't use setcpu use cm7 inbuilt feature with smartass governor(I am using smartassv2 governor because I am on mik's 6.6.1)
from settings >application>running services>stop the app or uninstall the app you don't need
also charge when battery is below 20%
Just set it at [email protected] smoothassV2,no need for profiles

For mi, te cm7 ia like the worst rom. Battery line is really low.

What is 'moderate usage' to you, and how long does your battery usually last?
Cm has a bug which causes wakelocks at.first. gets better in awhile

Try AGA-ROM with setcpu 480/729 smartass. You will need new baseband. Here is how to flash new baseband > http://forum.xda-developers.com/showthread.php?t=1149530

Tried it. It sucks.
48 hrs with moderate usage wont be easy. if you play games too forget it in any rom. im on cm7 6.6.1 with franco kernel and i'd be lucky to get more then 24 hrs but i do play lots of games and browsing and wifi on for 18 hrs a day . i found that using automation software like tasker or green power to toggle data or wifi gives a great boost to battery though.
I have a doubt: when not in use, the CPU is downclocked or work at 1.2Ghz.
If it isn't downclocked, there an app or something else that could be that? I think that could be usefull to improve battery life.
Download CPU Spy to monitor the CPU. It should go into deep sleep when idle.

Normal settings are for it to only run at 1.2 GHz when loaded. Also, in addition to downclocking, the CPU can go into "deep sleep" where everything shuts off.
The specific clock management settings can be tuned with an app like SetCPU.
Stock frequencies are 200, 500, 800, 1000, 1200 MHz.
I'm wondering if there's a way yo improve battery life... maybe it's better to install a custom rom?

Most people seem to gain battery life on custom roms. There are several to play with and, once you get over the initial hurdle of getting one installed the first time, you won't want to go back!

A couple options which I do myself are run all speeds undervolted by about 50 and set Max speed at 1000Mhz. Not sure if it makes a huge difference on battery life but it definitely doesn't ruin the performance, that I can tell.
Sent from my SAMSUNG-SGH-I777 using xda premium
Even 800 doesn't ruin the performance enough to start caring. Once I jump a new kernel I'll start tweaking undervolting and even crazier profiles.
Install a custom rom that removes bloatware and known battery drainers, and undervolt the cpu/downclock it to save most of your battery. Theres many threads about battery life, I suggest you look though those.
hey guys i install custom karnel on my xpera mini...now i can overclock up to 2 ghz..i just wanted to know pros and cons of overclocking..
pros- increased speed and less lagging,
cons- short battery time, increased temprature.
Is it possible to underclock it to get more battery or shelf life from the phone?
we can overclock and underclock if we install custom karnel..

Yeah. Root your phone, and install SetCpu, and you can Underclock freely and thus save lots of battery

Overclock will give you temporary boosts and lets you to showoff, and to get super high benchmark scores , but its not for regular use
Overclocking reduces battery performance and increases heating of device, which might cause your device to get unstable
and of course high temp = bad for the hardware so be careful
My SE mini works very well at 1610 Mhz.No crash,no instability but I use high frequency for max 2-3 hours or when I want to play without lagging
Pros
Immensely fast speed
Massive score on Quadrant
No lag or crashes
Cons
Battery life goes down fast
Phone temp goes up - Massive problem
Phone might get bricked if the phone gets unstable (Happened to my friend)
I only overclock my phone whenever I play games or need to switch between apps constantly. Though I always keep on 1024 as that is the default setting
Recently I overclocked to 2ghz was chkin stability and gosh I burned my battery, its workin but fone keeps restarting n I had to buy new one!! Dis is d con
Pro: faster n better performance!!
Overclock can cuz serious damage too!! But its fine to showoff a lil but in controlled envionment for a short tym!

Overclocking is not actually advisable because there are chances that it will affect your phone and might screw it up in the long run .
Battery drain is inevitable and you will experience it .
Phone will heat up
It may not be good for the other internal components because of the over heat-unlike computers a mobile is not actually equipped with much of cooling system.
There is a good reason why the manufacturer has set a clock speed ,otherwise isn't it better for them to just overclock a phone and sell it for a higher price ?
People who design the custom kernels are just telling the maximum possible value they could overclock to.
Pros-
Bigger numbers
Little more faster performance
it recommended to not overclock always..just overclock when you really need it..
What are peoples thoughts on a modest overclock to bring me back up to the performance I am used to?
Say taking an ACTIVE up to 1300 or so.
With these new NON-OC kernels, are they undervolted? I have seen claims of absolutely massive battery life and I'm reasonably sure some of those were using cpu throttling and an overclock.
So confused at this point. Also heard some of the newer ACTIVE handsets cannot even be rooted.

As in most things if you not overdo it you can enjoy the benefits of better performance without risking your phone.My xperia mini is running up to 1200 (1024 stock). Also minimum speed 122 instead of 245.So better performance when you need it and lower consumption when phone is sleeping.Overall i got the same battery life, 2-3 days as with stock rom.The best thing to do is get an app that lets you make profiles.Like when screen is off min cpu 122 - max cpu 384 etc...
I don't know about these new kernels you're talking about but cpu throttling is something stock kernels do also (if by cpu throttling you mean cpu speed adjustment)

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.

They say the undervolting on lower clocks should balance out the higher voltage on overclocks.

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.

Many of the kernels these days have their own tweaks and mod apps as well

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 .

If your running performance governor your cpu runs at Max Freq so battery is going to be terrible plus the fact you have high usage,
please give more detail like rom kernel etc if you use task killers or greenify, ram managers
Other things like gaming

Try using OnDemand governor and if you have it use nightmare governor as its performance based
and see how battery is also try wiping battery stats in recovery after full charge

pegasusq, LionHeart, SmartassV2 are good governors try to balance performance and battery.
row and noop are good schedulers, but sio performs better in dual core processors.
