Just wondering what sort of battery life people are getting with the touchpad on standby?
I am using cm nightly 9-20120608-nightly-tenderloin, the CPU is set to min 384MHz and the governor is set to powersave, but I am still losing about 25% battery in 10 hours on standby.
yh i'm the same too

The battery life for the touchpad, in android, is not good. It you know you're going to turn yours off for a while, either go into webOS, or shut down completely.
yeah I am tending to shutdown the touchpad to save battery
life. Can't remember the last time I booted into webos

With a CPU governor and the proper profiles, you can get pretty decent battery life. I suggest CPU Master.

What is the reason to set the min. frequency to 384 MHz?

It solves a lot of the sleep related issues.

It seems the CPU scaling is not set properly with the kernel that cause the phone runs warm and decrease battery life. Checked with CPU Spy and I noticed it often idles around 1134~1026MHz, instead of all the way down to 384MHz.
What you need:
1. Download any CPU control apps, like AnTuTu CPU Master, No-frills CPU Control, CPU Tuner...etc...
2. ROOT!
3. Set the minimum frequency to 384MHz. Leave all other parameters unchanged.
4. Check Apply on boot.
Now check with CPU Spy again you'll see your CPU idles at 384MHz and your phone is running cooler.
Yeah seems the kernel needs to be tweaked a little. It will most likely be patched by .1

the phone goes in standby, but the cpu stands over 1000Mhz instead of scaling at the bottom?
Mine already goes down to 384mhz without intervention of any CPU apps. At this very moment my CPU is at 1% and clocked at 384mhz.
I don't think doing this will have any effect on battery life or heat.

Mine aswell. Clocks down to 384 Mhz when doing nothing.
Thermal throttling is NOT supposed to throttle to minimum, its not a rollercoaster. It would lag terribly intermittently. Perhaps the threshold needs to be brought up, but the throttling clocks seems about right. Something else that could be done and help a lot is adjust the voltages.
Edit : sorry I misread your post.

Mine does go down to 384MHz. But my point is the CPU does not go down to 384MHz when it should be.
From CPU Spy it seems like when idling the CPU half time stays on 1134MHz and half time goes down to 384MHz.
After the tweaking the CPU goes down to 384MHz all the time, and does NOT affect smoothness or fluency of the system.

Mine oscillates between 1 and 1.5 Ghz while in use, and goes down to 384 when lightly used or when WifFi is on (Wifi prevents my phone from entering Deep Sleep). The rest of the time, it's in Deep Sleep.
384 is the minimum? Damn, I remember when 384 was the maximum.

im just wondering how much does the governerr effect battary life? i changed from ondemand to smartass2 and im not sure i see any diffrent...
and im scheduales which one is best for multitasking and which is for when playing games?
and should i change the governerr setting?
i also read that sleep_ideal_frequency should be 200 and not 100 beacuse 100 wastes more or something like that, is that true?

I use Performance governor all the time for 3 months now, battery life is same as on demand, smartass v2 or any other governor, except my phone lags much rarely than on any other govenor. For those that dont know, CPU of PC, your phone, calculator or anything else always works at 100% of its frequency even it has no work to do (Let's take for example your PC, even cpu usage is 5%, CPU still works at full frequency, the same works for your phone), so to me there is no point of any other governor except for Performance. If you have problem with battery life, it's mostly your screen. When I drain out my battery, my battery mostly get drained by screen (70-90%), I use about 0-30% of brightness always. Screen of 60-100% brightness will probably drain your phone's battery in 2-3 hours.

This is so wrong its a pain to read.:banghead: Why do we have the max and min frequency options in the semaphore app? Why do we have "Max Performance" and "Max Battery" power settings on laptops?

There was a thread some while ago that concluded in OnDemand and Performance being to two to give longest battery life and best performance.
I don't have specifics or even a link, but the thread was about schedulers and governors and which went together for best performance and battery life. I'm sure it's google'able

i found that thread but im just wondering how much battary life is wasted if i prefer preformence?
lets say i use smarassv2 since its faster will my phone drain lets say insted 20%\hour - 22%\hour? or is it more then that?

maybe you can try and tell us
There should be a significant impact regarding battery life when using Performance for example. But it also depends on what you are used to. If you play games all the time or do heavy tasks, the governor will kick the CPU to 100% all the time anyway. But if you mostly surf on the Internet or read texts there's no need to let the CPU go rampage.
Oh and Btw: Modern CPUs in notebooks or computers in general clock themselves down as well when they're idle.

Hi all guys, I have got stock rom with a custom kernel for a lot of time. But with Cm 10.1 I can't get the same battery life and I don't understand why. All people here say the have more than 3 hours of screen-on time. But I can't say the same and I don't understand why.
I have optimous prime kernel and cm10.1 and I set every time these CPU frequency:
Min 102 MHz
Max 1.2 GHz
Interactive Scheduler
I don't have any strange app that cause drop of battery. I was wondering if Facebook app can drop it, but I have setted Facebook to don't synchronize.

Install better battery Stats or any other app that measures the sleep time of your phone, and see what's keeping your battery drain and / or keeping it from going into deep sleep
he is right. some app must drain your battery otherwise the battery is dying. also i can say that 1.2 is really low. mine is 1.7 and is running like a lion for around 3 hours too.
HI I am having heavy battery drain
running version from 15/03/2014
I had a maybe 3 minute phone call but still the phone app has eaten up 37% followed by 31% android system
total 72% left after 1h36min
This is a new behavior, up to last week it all worked smooth.
the CPU governor in nofrills CPU is now set to performance since on demand or power saving make the phone very sluggish
Also Video app is not working, just crashes same result in Focal
Any ideas or tips?
Thanks Merlin
You do realize the performance CPU governor makes the CPU constantly run at 1 GHz? This will of course drain your battery.

It's maybe the 1GHz bug. The 1 GHz bug cause the heavy battery drain. Try this, turn off wifi and reboot.
its 1ghz bug if you are using ondemand. but i hope you know performance governor keeps cpu freq. at 1000mhz.
im using abbysplug/sio governor. and my battery lasts for 18 hours.(wifi or mobile data on. sms Messaging. whatsapp. facebook games rarely)

abbyssplug change the processor performance. You can find it in Settings > performance > processor > CPU governor
go tp settings>about phone and press repeatly to build number. you will see "you are a Developer now" text. go back. performance menu must be appear. you can set it there cpu governor.

A fellow user thankfully redirected me to this thread and told me about this governor setting you mentioned above and i must ask you some questions if you dont mind of course
1- What's the difference between Abbysplug and Powersave governor? I have my phone underclocked at 200 at all times and the sluggish speed never seemed to bother me much, so is there a difference between these 2 governors when it's at 200 all the time?
2- Have uninstalled/frozen/disabled any system or built in apps?
3- You leave the mobile data on for 18 and the battery lasts????
Please give me your exact settings, man; i'm desperate. :crying:
I know that on all my phones I underclock them to be able to conserve as much battery life as I can. I was wanting to know how many other people underclock this device and what are the setups they are using? I, for example, am using LiquidSmooth v4 Nightly 12/23 and Sensei Kernel R26.1 underclocked at a max frequency of 1.1GHz. I have CPU hotplugging enabled and only use 2 cores.
What's your SOT with that set up? With the stock frequencies I can't get 6.5-7 hours SOT. I'm running LS 12/24 with Lean Kernel OCUC set at 300mhz-26496 I.e. (.3-2.7ghz) and the standard interactiveX Governor that is with it.
Why not just leave it in Battery Saver mode all the time?

And I have a problem with battery saver mode on liquid smooth. It doesn't vibrate upon receiving a notification. And it seems like it only does that, and turns off animations and lowers brightness

I believe it also locks the CPU clock down and turns off auto-sync on accounts. On my phone if I use it it tells me I have like 3-4 days of battery left
I am currently under locked at 1958 and my battery life improved drastically. I'm using Set CPU. Here is a screenshot. I'm currently on Chroma. I havent noticed any lag what so ever.
