hey guys, i am experiencing huge battery drain on cm7..it was fine till i was using 6.5.7, but when i updated to 6.5.8 my battery drain got really big..1-2% every 10-15mins on standby and 5-7% while playing games and using data for only 10mins!!..so i switched back to 6.5.7 but now am having the same problem with it too...my setcpu is 748-600..help?
Don't use setcpu
It runs ad service so eat ram a lot
Use no frill
And use Fserve kernel also used this setting
480 to 729 MHz
Smartassv2
Still getting same problem.then try.my rom arc_os which is based on Mike 6.5.8

Try wiping everything, formatting boot and system, then flash ROM again.
Charge battery to 100% and calibrate it.

Just installed No-Frill (just wanna see, what it is and what it's doing. Was using CM7 built in tool) - one question - which I/O scheduler u recommend to use?

Just use built in cm7 cpu settings instead. For IO try noop.

Download Battery Calibration from Market
boot into recovery and wipe battery stats...
this works for me whenever i got high battery drains..
check if your phone is getting hot, if yes, open spareparts and check the high cpu usage , check what app is getting rogue, kill it, or better reboot your device! then install watchdog lite to monitor cpu usage, also check what keeps the device awake on spareparts. hope it helps
Actually the most common reason is the phone CPU being awake all the time. You will fix this by reflashing your ROM (without data wipe).

Hei guys, I'm really, really new to this.
I've just flash andy's port of CM7 based on 2.3.4. I'm having a really though time with the battery, it goes down 50% faster than on my previous 2.2.2 official Froyo from LG.
Anyway, this question is about overclocking.
So, inside CM7 settings there's this "Performance" menu, in which you can go to "CPU", I've set there smartass governor, minimum 122 and maximum 768.
What does that mean? Does that mean I'm overclocking my CPU? Does it mean that smartass will allow or push the CPU to 768 when it's needed? Do I need to do something else in order to achieve that? (i.e - use get the CPU at 122 while screen off and increase it according to demand up to 768). - that's what I'm after.
Any response on the topic(s) much appreciated.
Thanks.
Regarding battery - calibrate it with the app from the market
Regarding OC - yes, when you'll use the phone your cpu will run at 768 mhz (note that you might get kernel panics). Your minimum speed is pretty low and it will take a little longer to get to 768... you will see some skips or lags.
Oh, and yes! You're overclocking and smartass will do what you're looking for (idle-122/in-use-768).

I would kick the min up to 480. That usually gives you a good balance.

Thanks for the fast response.
As for the battery, I tried calibrating it and still the same.
I'm reporting 10% (exactly) each 2 hours, in idle, screen off, everything turned off except mobile data on EDGE.
At this rate, the phone goes dry in exactly 20 hours with minimal to no use. This isn't normal.
It heats up when charging (more than usual).
In battery stats I have all the four ones (android system, cell, etc.) at 25%.
No apps installed.
Just a few hours ago I tried replacing the stock kernel of andy's with the latest from franco (16) and zram.
Exactly the same.
I don't know what else to do, I already reflashed it twice. Same results. I can't post to the development forum just yet (not enough posts).
I guess I'll just go ahead and try mik's port... although I wouldn't want to, I love this one, everything works perfectly except the battery thing.
Did you use google maps?
"Known bugs
[...]
- Google Maps is eating your battery, kill this app after using in Setting->applications
[...]"
i think smartass does automatically change your cpu's frequency when you need it..but your minimum frequency is too low..change it to 320 Mhz....and are you using 3g all time..??
Yes, used google maps but killed it. Second reflash didn't even install it and still the same problem.
No, I didn't use 3g at all.
I only kept mobile data active on EDGE. and as I said, it was in idle. it's like the phone was used 24/7 even in idle.
and why is my cpu to low? the phone works like a charm with that frequency.
Check the 2 g networks only box in settings-networks- mobile networks....that may be the reason
Sent from my LG-P500 using XDA App
It's checked alright. Like I said, I used it on the EDGE (2G) networks.
Anyway this doesn't matter anymore since I've switched to mik's rom.
you can give void# forever a try too...gives me two days battery life on moderate use...
Okay, I will.

have you tried the new GT 2.3.8? claims better battery use, i installed yday and it lasted for the day at least..but that was quite minimal use. underclock with setcpu, i downloaded app called cpu spy it informs you what speed your proc is running at and u can get a decent reading on when and how long the speed is which helps in set cpu if you set up profiles so i.e when yr battery reaches x% the clockspeed will reduce, and choose a governer like powersave or conservative...it does make quite a difference
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

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.
Hey guys, i was just wondering what apps you guys use that actually work to improve performance of the phone in battery and speed?
Sent from my SGH-T959 using XDA App
Check out this guide made by Woodrube. The third post has a list of apps designed to prolong battery life. My favorite is Juice Defender. It's worked wonders for my phones battery. The guide also discusses other methods of increasing battery like undervolting [must be rooted to undervolt] (post 2) and other misc. things (post 1). I suggest you take a look at it.
As for increasing speed performance that's what overclocking is for. You must be rooted to do this and have flashed a custom kernel. Then you have to have installed an app like SetCPU. Just keep in mind that overclocking drains battery. Overclocking to 1.2Ghz shouldn't hurt the battery too bad and have increased performance, but it will drain faster then not overclocking at all. Underclocking is good to prolong battery life, but will reduce performance.
Hope you are able to get the most out of you battery
Thanks for the plug N00B.
Also if you are on Stock Kernel, you can use Tegrak's Overclock and overclock your stock kernel. It will work on 2.2 stock based ROMs. That in conjunction with SetCPU you can overclock your stock ROM easy-peezy. It also has a 5min compatability time to see of your settings will work or freeze/restart. There is a paid version too with more functionality and "set on boot".
You should definitely consider downloading "Watchdog Task Manager" from the Market, as it monitors what is using your CPU and how much, so you can keep power hungry apps under control. Its a "real" task manager, as it doesn't close apps based on the RAM that they use, which is what the Android OS already does.
As for OC, I use Antutu CPU Master, and keep it at 100-1000/1200mHz while in use, and 100-800mHz if I'm not. Hope this helps.
Im on stock 2.2 with bail uv and its great i get scores between 1700-1800 abd battery is awesome and im using auto minfree im just looking for an edge. What do you guys think of minfree apps?

my usage will be: mainly Trillian, some daily-use Apps, OSM Navigation sometimes.
so i dont need eyecandy-blingbling fullysocial integrated Walkman stuff; so i dont want a Stock ROM
i very love CM 7.2 (Android 2.3.7) on my Ideos X3, but i heard CM9 should be more better
so... can you tell me please
what combinations are you using?
how are you using your phones?
and how long does your battery last finally?

Well,I m on MESA 1.6 Kernel and Stock ICS ROM at the moment and battery life is pretty good.
It ranges between 16-18h with heavy use up to 36-40h with light use of the phone.
They key thing is getting rid of all the bloatware that stock ICS has,plus using profiles as far as CPU
clock and Governors are concerned.I m sure that you know all the other tricks like a lower than 50%
screen brightness and Synch OFF and stuff like that.
Hope I helped.Good luck! Experiment and you ll find a good combination of settings.
N.
before installing any custom rom you have to first unlock bootloader then after flash underclock to increase battery lifetime
I did read somewhere that rage kernel is the best for getting the most battery life! Gnna try it soon !
Also use smartassv2 as ur governor with noop ... Underclock ur processor a bit
( I use mine at 834 MHz, runs smooth) ..u can always bring it back up if u feel like your phone is getting a little laggy.

I have tried both CM7.2 and CM9.0 RC2 on my XMP. CM9.0 RC2 still has some bugs. I have installed it twice. It boots ok but I have got two severe problems. There is a weird screen at the very first boot which tells you to input SIM lock key. I couldn't get past this screen. Another time, the launcher didn't load no matter how many times I rebooted.
I tried CM7.2, the ROM is very good and usable. But I don't know why my battery drains too much fast. I flashed the ROM while my phone was fully charged and also wiped the battery stats. But no good, the battery drains way too fast.
You can try kamarush's MiniCMSandwich Lite AOSP with Rage kernel or Krsh kernel. Very good ROM with very low battery drain.
I was using CM9 Stable on my XP Mini for the past week.
Battery life sucked really hard in comparison to MESA Kernel/Stock ROM.
We re talking about 10-14h for a full charge using Data (3G).
I m back on MESA/Stock again.
N.
Try Extended stock kernel with miniCMsandwich lite.
Sent from my SK17i using xda premium
CPU max: 768mhz min: 249mhz
I lowered voltage by 50mV for all frequencies with "system tuner"
Governors: scary, smartassV2, interactive, brazilianwax. SmartassV2 is the most popular all around governor.
I'm also using "perapp" application. It allows me to set different CPU frequencies individually per application. e.g. when I enter a demanding app, it upscales the max CPU freq to 1ghz...
Try to use a light ROM, or simply remove bloatware manually.
Consider GB since it's less resource demanding, less lag and faster then ICS.
Xtended stock kernel{ICS} by expeacer has a good batt consumption. Rage for GB&ICS also.
For CM7, you can use ported Rage kernel by user greenalgae.
