Hi
So I have a rooted Nook Color with CM7 Nightly Build 41 and Dalingrin's OC Kernel running at 1.1Ghz max / 800Mhz min. I have not disabled Cell Standby and i use Launcher Pro. My Nook's battery life seems to be less than 5 hours while i have seen other people get 10+ hours in the same situation. I have been using it considerably but i would think that my battery life would be greater.
One thing to note is that i did NOT fully charge the nook before using it like it said. Would this be the cause of such a low battery life? If so are the batteries replaceable?
Thanks

its because you have 800mhz min, set it to like 300
Well thats including standby but i have been running emulators for N64 and NES etcetera, But it seems like even without running games the battery drains rather quickly
Heres my Battery Statistics:
Display: 57%
Phone Idle: 9%
Cell Standby: 8% (Yes i know this can be disabled)
Android OS: 7%
Market: 5%
Dolphin Browser HD: 4%
Bluetooth: 3%
Wi-Fi: 3%
Cordy: 3%
Will setting it to 300 affect any performance negatively? Whats the benefits of having a higher min?

it will not make the performance worse. setting it to 300 means that when the nook is doing nothing it will be at 300mhz which uses less power and battery.

^this, instead of idling at 300, with your settings you are running at 800 all the time, thus your battery life is terrible. also set governor to interactive. if you have it at performance it would be running your nook at 1.1 all the time.
I think the default governor on Dalingrin's kernel is set to ondemand. Is interactive batter with battery life?

Conservative is better with battery life. Dal recommends interactive, since when the screen sleeps it drops to the min cpu setting and can go up to max if necessary. If you want a little more power he recommends setting interactive min to 600 although this will hurt battery life some. He never recommends performance as that keeps cpu running at max only.
There is a new testing 4/24 OC with max of 1300 for most and 1200 if 1300 does not work for your nook. He say that this has little effect over 1100 as the majority of battery life is determined by the display. I am using 4/23 OC at 1300 max, 300 min, governor interactive. The 4/24 OC kernel has the additional 1200 setting plus other improvements. I will probably upgrade to it.

You don't. It's pointless and just causes other problems, such as your volume keys won't work..
So how is battery life with the latest stable or nightly build?
I'm going to take the plunge and install CM7 tonight coming from an autonootered Nook running 1.1.
I've read that the devs have found a fix, just wondering if they have filtered into the newest builds.

I've been getting verily bad batter life with my Nook (7.03 stable) and SetCPU at 1200/1300Mhz with interactive. I've played with it for 2.5 hrs and it has dropped 30%. Mind you, I watched one 30 min tv show, played two games for maybe 20-30 minutes, and browsed online and taptalk the rest of the time. Display settings are very low at 20%.
You aren't supposed to run SetCPU with CM7. Use the built in OC function and/or install an OC kernel.

So, how would you set your low value (i.e. at 300) without SetCPU? I don't recall the default CM7 settings having this option (just the high OC).

CM7 allows you to set Min/Max CPU Frequency as well as governor from within its own menus.
Settings -> CyanogenMod settings -> Performance -> CPU settings.

The fix isn't in the stable or any of the nightlies yet. The most recent nightlies have a different fix, which prevents the speaker from running constantly, so the battery life will be better than it used to be, but nowhere near as good as you would get with real deep sleep.
The real deep-sleep fix is in the CM7.1-RC0-beta3.1 build. Its still a beta, and a few people have had some glitches, but it is running fine for me. And my nook now has the kind of battery life it had on rooted stock (before being unable to prevent an auto-update nudged me to CM7).

you can run setcpu actually. the thing you can't do is run profiles on pre-beta kernels with setcpu.
set your minimum to 300mhz no matter what you use.. anything else is overkill that will result in battery kill..
in addition phone, mms, and telephoney apks have been proven repeatedly to have no impact on battery.
occasionally after flashing a new rom, recalibrateing your battery stats will do wonders.. ie. charge to 100% go into CW and reset battery stats, let it drain to below 10% then charge back to 100%. This is true of most Android devices.
The new beta build and kernels have improved battery a ton, they say these fixes will be incorporated to nightlys then stable CM7 eventually.
Hi there,
I've been using revolutionaryHD 2.1.2 for a while now and last week I realized my battery life was not what it used to be. So I decided do do a full clean reinstall (format+wipe everything + battery calibration) hoping it would solve the problem.
However, the clean install did not solve my problem. I have now installed cyanogenmod nightly, believing it was revolutionaryHD that was causing my problems and ran some test with currentwidget.
Screen on, everything else off = -126ma 4.11v
Everything off = -38mA 4.11v
I've read a post stating that battery drain should be between 1 and 10mA if you enable wifi, I didn't even enable it .
I have NO idea what is causing these high numbers, so I would love it if you could shine some light on the subject.
Best Regards
Yannick Wellens
Hi Yannick,
I think 38 mA is a good value. The battery of the Incredible S should have 1450 mAh. At a current of 38 mA, it should last for about 38 hours.
Greetings, Richie
Best settings ever:
CyanogenMod nightlies 146
Tiamat kernel 1.13
Oc 1400000
Uv all values -75
Turn off gps and wifi unless needed as well as any location services
Do not run app killer or any other background processes

Yeah, I checked with a mate's desire S and he also has there values on a stock rom. I'm wondering though if the facebook app is a battery killer, any comments on that?

Definitely. More so if you have a widget.. In fact any widget that gathers info from the web will keep you from entering deep sleep. Grab cpu spy from the market to see how often your device enters deep sleep.

Try to calibrate your battery. =)
I seem to be having quite a problem with battery drain as since I updated to 5.5 my phone battery seems to be getting really hot and does not seem to last as long as when I had RC5.2.
So my question is what is the best way to prolong the battery life of the phone.
P.S I leave wifi and bluetooth of when they are not being used

use 2g , not 3g, more power... make display darker xD, take off sync from google, take off autorotation... u have more power after this.. u can set ur cpu lower, thats make a lot
Set min CPU freq to lowest available value (its 122 in my case) and max CPU not more than 800. Also choose a suitable governor for you...
First calibrate your battery and completing the process use an app. like power saver or easy battery saver etc.Dont use live wallpaper or too much widgets....

Alternatively you could take the overclocked NoteCore kernel and underclock it.
The kernel is undervolted, so disabling higher processor frequencies will give you the benefits of undervolting and the benefits of underclocking.
I.e. low power consumption and low temperature.

Its not a 4.0.4 LRK issue. I was running a rooted stock build and installed NoteCore kernel without any issues. When I flashed Rocket V10 it was only then that the battery life became crippling. Shame, I love Rocket and the tweaks but guess I'll go back to stock!

Sent from my GT-N7000 using xda premium
Take a look at the NoteCore thread in the development section for the undervolt details.
The overclocked kernel is undervolted.
Install the overclocked kernel then use something like Tegrak to limit the processor frequency to 1400 or 1200 then you will get the reduced battery drain of using lower voltages and lower frequencies on your processor.
Don't change the undervolting set in the overclocked kernel add this had been optimised.

I don't think it's the kernel's fault for the battery drain.. I think it's the modem..
I have been using notecore with all the touchwiz roms no battery problems at all
RR 10 with NoteCore 13
Just installed NoteCore 13 8hr ago, and plug the power cable for charging. Still plugged now, but the SpyCPU report shows that during the past 8hr, the phone didn't go into deep sleep (while I was ) , but it stays at 100Hz.
Will unplug now and go to work for a day. See if I can get a usage report after work.
Cheers
Yep, definitely faced the same problem, which was the reason I switched to Classic Rom V4 (because of the newest firmware) but actually, though battery life is better, it is still worse than with AlBA v4...I haven't been able to determine whats behind it...

After a normal day usage... The battery drain is still heavy... When screen on, the percentage dropped around 1% per a min or two.
Dunno why... Deep sleep state is ok.

2nd of RR10 with NoteCore 13. The screen-on drainage improved. I read my whole travel time (around 1.5hr) on newspaper via 3G signal, and the battery went from 100% to 81-82%, which is acceptable for me.
Again, Deep sleep works perfectly.
I left this good rom because of this, deep sleep ok, but when the screen is on, too heavy battery drain. same with 2 kernels, should be another reason.

I tried with notecore and speedmod. I have used RR10 about 3 days to have several battery cycles. but I felt a big battery drain when using the note, even at low brightness, with nothing strange in CPUspy or BetterBatteryStats.
so I switched to JB liquid. Yesterday night. I would not say it is better for the moment to be honest. New rom, new kernel, not even a beta, so hard to compare, but you are right I feel the same today: high drain with screen on.
(but whatever the battery drain, with palm rejection available on CM9/10, I will switch again to a sammy rom)
I really cant seem to find a way to lower the screen on battery drain , its ,horrible ,
been on latest std notecore and speedmod , and with both i cant seem to get more than 2:00 - 2:30 hours of screen on time & basic use (in total of 10 - 12 hours ) , deep sleep is perfectly fine with 1% loss per hour (sometimes even less !!) , but with the screen on , battery just goes bursting -1% per minute........
we do need our devices to be used , not rested on deepsleep the whole time , otherwise this defies the whole concept of a "smartphone"....
on GB it was very good ,it got worse when Samsung introduced ICS (but was manageable) , but now on 4.0.4 , its just horrible and unacceptable!!! dunno what kind of testing Samsung does before rolling out an update...
sorry for the whole rant and rage post in there , had to speak it out cos im struggling here..
would be highly appreciated if someone can help or a suggest a 4.0.4 rom with a "reasonable" screen on drain... im even considering going back to RRv7 (4.0.3) cos as far as i remember i was getting good battery out of it (deep sleeping and screen on was great there)

how much your battery last in standby mode?
Guys I have created this thread Coz I'm really confused as I don't remember how much my battery used to last before I was into flashing daily roms...now I'm on temasek 134.5 with Stephan kernel..and my battery drains almost 8-10% per hour without data,, wifi on and also 2g mode.baseband and ril matching...also I smart flashed calibrated underclock and undervolt and still no success and the best part is I recently bought brand new authentic lg battery from lg showroom I searched almost all forums deleted Google backup transport.apk also as in some forum it was mentioned tried all roms and all kernels the drain pattern is almost similar..kindly help guys..

i think that is Temasek 129 or 130 (not quite sure because the settings show 1xx, but i know that every newer rom 131-135 didn't work for me)

btw this 2 day battery life is with processor 216-1100 Mhz setting (not with that 1504 mhz from antutu screen)
Guys any idea why my phone. Sucking. Battery even. No app instaled. Bare. Rom still. Drain. On standby no wifi. No data. No phone. Call same drain?

It actually did happen and it wasn't a battery reading bug. After a few minutes of usage my battery percentage sunk by 1%. As usual. No clue how that happened but the room was seriously cold (around 2-3 degrees Celsius.) and I haven't touched the phone at all. Also the processor was clocked at 216mhz the entire time.
Unfortunately that was back in June and I have no way to prove it. This did really happen though. I was pretty shocked too when I saw the ridiculously low drain.
