Does my battery life look right? How can I improve it? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I picked up a Galaxy Note the other day to mess around with, and have noticed that the battery life isn't fantastic.
I'm running Slim Bean 4.2.2 build 7, and NX OC kernal. The only relevant settings I've changed in the kernel utility are the clockspeed (from 1.4 to 1.6) and the governor (from Hyper to SmartassV2). Battery is stock.
Here's an Imgur album with screenshots of everything I think you'd need to see: http://imgur.com/a/fAUR7
Now, am I missing something, or does this look right? Should 'Android OS' be using that much battery?
Thanks a lot in advance for anyone that can help.

What's your screen-on time? To check that then go to battery and tap the screen. (report when the batter is nearly dead - below 5%).

Whoops, I missed that.
At the time of those screenshots, it was at 1 hour and 15 minutes, give or take a few minutes.

Ran the battery down playing some games. Updated screenshots are here: http://imgur.com/a/16ZRk

OK, so first and foremost then playing games will use a lot of battery. Usually you can't get more than 2h of intensive games. However the android OS usage is very high, install Better Battery Stats (search on XDA) and post the result. Also did you perform a clean install? As in did you perform the following wipes: system, data, cache, dalvik cache, preload?

The battery seems fine. It is normal with high Android OS. Same on my phone. Beanstalk + NX kernel. I managed to get around 2-3 hours of on screen time with gaming.

That's good to know.
I just bought myself a 7000mAh battery from Hong Kong, so I shouldn't have any issues with battery life now.

Do please keep us posted with how the battery performance is. Could u post a link if you bought it online..

Poor Battery Life On Overcome Jupiter

Hi,
I don't have sufficient posts to be able to participate directly in that forum, so have no other choice but to raise my queries here.
I've just flashed over from Overcome "Hermes" to "Jupiter". All's well except that the battery performance is quite drastically affected for me.
I've been reading the improved battery life "Jupiter" gets over earlier versions of the Overcome ROMs, but I seem to be experiencing the opposite.
Already did the batt stat wipe via recovery menu. Do I need to so call "run-in" before it reflects correctly? Even if accuracy is one thing... but dropping 3% just on bootup.... is this typical of an uncalibrated battery?
Appreciate any advise here on what I should do. (Apart from a fresh wipe install )
Thanks
I appreciate the enthusiasm these coding geniuses have in rolling out update after updates in the ROMS yet I am apprehensive about the effect of these frequent flashing on the Galaxy Tab components itself. This includes the battery.
My job involves electronic repair and there is a so called number of hours before an equipment goes for a thorough check(preventive maintenance) say for example 1000 hours on a meter. Unfortunately the galaxy tab (or any tablet) does not have this. So if you frequently do a flashing on your tab you subject the electronic components to unnecessary stress,thereby affecting the life of the components like the battery.
In "normal" everyday use of the tab you will seldom do any restart/reboot of your tab,yet in flashing ROMs as many as 3 reboots is needed. As I don't know how to measure the surge in current during reboot, I can just imagine how high an initial current during startup is generated, thus putting a big strain on the battery.
Unfortunately the battery is not user detachable.
There was an author here in XDA describing himself/herself as an "flashing addict"(or something similar). I would like to appeal to everyone-please don't be a flashing addict.

According to the Tweaks section at the team overcome website, it will take several charge cycles before you notice an improvement after the stat wipe. Try giving it a few days before going any further.
PS Not to question your ability to follow instructions (sometimes we miss things) but did you charge to 100% with the tab off?
Yes, I did charge to 100% with the Tab off.
Now upon reading the instructions once more..... I might have conducted it slightly different from the written procedure.
I unplugged the Tab from the mains, then only booted up and wiped the batt stats before re-booting. Hmmm.... maybe I'll go try booting up while still plugged into the mains, do the batt stat wipe, and re-boot. (all while plugged into the mains). Then only unplug the charger.
Wonder is there any diff in doing so.....
Would definitely try re-doing it with the tab plugged in while doing the stat wipe. And if it doesn't seem to fix it, do go through a few cycles before reverting back to a previous ROM.
It's important to completely drain your battery before recharging it to 100% in order to complete a cycle.
Hope you fix it. Battery life results vary between tab's even if they are used very similarly, I'm running the OVERCOME Jupiter ROM with IMPROVED battery life. I keep my Bluetooth, Wifi and GPS on all the time. I also flash quite often and have not seen a decrease in overall battery life. It seams that each tab is a bit different, hardware wise, than one another. Everything from battery to board it seems is slightly different coming out of the manufacturing process.
Thanks. Will try that out.
But it just seems strange coming from Overcome ver 1.4 (Froyo) which had no batt drain problem.... to Hermes which was better in batt performance.... to Jupiter which I'm experiencing heavy drain.
As I did a NoWipe install, all apps and setting are similar (except the new market app).
I was able to run 2 movies back to back (about 3 hours total) and still have at least 40% life left (usually about 45 to 50%). Now on Jupiter, just fiddling around testing the various features for functionality, plus maybe an hour of NFS (total about 3 hours as well).... the batt drops to about 10% life.
Anyway, I'll re-do the calibration and and give it some time to "settle in". Hopefully, that is all that is needed. (I would hate to have to do a full wipe install... and re-installing all apps)

As mentioned in the Tweaks section, perform the Stat wipe and then two full recharge cycle
recharge to 100% (while the Tab is closed) then drain the battery till it is off then repeat the cycle and you will enjoy it man
Please tell me if you need anything

Viewed purely from an engineering perspective, I'm unable to see any significant connection between the flashing of the ROM and a degradation of battery capacity. Further, in the event that the TAB was connected to a charger during the flashing, I can see absolutely no connection at all! Please help me understand your logic.
Ok Back on topic. PCdumb (dude what's with the username lol). Check your app list. It could a new app you or an old app you updated or an app you didnt use before but you use now that is being a battery hog. A small trick I learned is checking apps running services in the background. Go to Settings, applications, running services and check (why is skype working after Isigned out its not a battery drainer but I hope you got the picture).
Thanks for the advise. That was one of the 1st few things I did to check that there's nothing out of the ordinary running in the background and taking up the juice.
Mine's actually draining alot when in usage. Not too sure about when in standby.... will check later.
If after a few charge cycles and the drain is still bad, guess my only next best option is to do a full wipe, re-stock and re-install.....
I did not get any effect from Battery calibration. As expeced. Anybody did actually?
The background services instead might have an effect on power consumption, I agree. But needs numerous testing...
Batt recal did not give me better battery life. There's no difference in the battery performance after 3 recharge cycles.
My tab can at most get slightly more than 5 hours of continuous usage compared to about close to 7 hours on hermes. This is when i dial down the OC from smartass mode to conservative and also put the min freq to 200 instead of 400 which was the setting i was using all the while.
Doesn't seem to be anything else running in the background. On standby overnight, i only lose about 3% which is not too bad. But when in use, that's where the Batt drains fast. Just for comparison, i only lost 1% at most for overnight standby of about 7 hours when running hermes.
Guess I'll have to live with this if i want the speed and smoothness. Still contemplating whether to restock and do a clean flash.

If you want to confirm that JUPITER is the reason that you are experiencing poor battery life, try re-installing a previous version that you feel worked better for you. Maybe reverting back to a previous version may yield better battery results, and I sure hope so, this way you will know if it's the ROM or other elements affecting the abnormal battery drain.
If you do see an increase in battery life, try flashing JUPITER again, see what the results are. I don't know if flashing and re-flashing will have a negative long term effect on your SGT, I know that I flash every time a new release is out (Stock safe, cooked ROM, Kernel) and if i'm not happy with the release i go back to a proven one by flashing another three times (stock safe, cooked ROM, Kernel) and so far I have not had any (knock on wood) abnormal battery activity.
It's worth giving it a shot (if you haven't already).
EDIT: I know, I know the proper sequence is stock safe, kernel, rom.
after week of using the Overcome ROM i can confirm that the battery performance is between 85 and 90% from the Orignial stock ROM performance
No problem since this is normal as we are using a cooked ROM

I do get 4 to 5 hours of continuous use with overcome Jupiter, mostly browsing the web over
WLAN or umts. Hermes release didn't gave me so much more juice, probably 5 hours.
In the background I have emai push, contacts and calendar sync and some instant messaging apps, if I switch off all that I might get an hour or so more.

Wow, maybe your tab is one of the ones with a battery from the bad batch, and it's finally on its way out. I upgraded from the stock AT&T Rom to Overcome Jupiter, and on Airplane Mode with all stock settings (no overclock or undervolt), mine only drops 1% in standby over 14 hours and I can get about 5 hours of video watching straight with the brightness on max before it dies!

I also been experiencing a major increase in battery drain even after doing a couple wipes exactly according to the tweak guide. I went from about 24 hour normal use down to 6-8 hours normal use.
Checked the services as per your suggestion above and found a couple major battery drainers running. Skype and Yahoo but also Google+. What I dont understand is why Skype and Yahoo would be running even though I had not started either since at least several re-boots ago. I had Skype and Yahoo installed for quite a while Google+ is a new one. Anyway I killed all of them and now and will see what happens next.
Not sure thought that this is all there is to the issue. Recahrging is finiky as well. I can turn off the tab and let it charge all night just to find that it charged to about 70% if I re-plug it might charge to 90%-95% and then if re-plug it might get to 100%. The drain from 100% to 60%-70% is extremely fast and still quite fast from there. On one occasion after complete drain I couldnt get it to start charging at all for about 5-10 minutes. I was checking power, cables, connections and starting to panic when all of a sudden it started to charge.
Any advice on possible reasons or solution woud be appreciated. Not sure I want to go beck to stock ROM and un-root just to take it to service center for repairs.

[Q] Having fast batt drain after installed Oversome 3.1.1

Dear all,
I just upgraded my tab into overcome 3.1 from my initial GB 2.3 . The reason why i started to discover some issue on my batt usage is within 2hrs it will take off 20% of my batt when i fully charged in the morning.
After which i check on my application - batt use - it show "display" is at 92% on the top and android system is at 2% at the bottom. Whereby when i use GB 2.3 rom, it will show andoid system is at 80~90% and display is at the bottom of 3%.
(Note: i have even set my display to the lowest and set it to Auto mode, some of the un use application i also shut down)
I have started to think should i change back to GB 2.3 or is there any brother outside can advise what should i do to change this situation. Hope someone can help me on this ..... Thanks in advance.

dear all, after further confirmed, my colleagues also having the same problem as my, I was wonder is there a bug in this version as em not sure why the consumption of the battery was so high after installing overcome 3.1
First of all, old ROM had a bug, battery usage was displayed wrong. That is fixed, but they are now working on R2 version of kernel (Reverted lowmemkiller change which may have been blocking kswapd0 from sleeping, resulting in battery leakage).
This last kernel has a new ROM as it's base, so you have to install new ROM first and then full wipe version of kernel.
Good to hear I am not the only one.
Hermes was an awesome rom concerning battery stamina. I hope the guys from Overcome will make this R2 release just as good.

The latest version of the overcome kernel is pretty good on battery life for me.. the only thing that seems to be wrong is the reported charge level against the battery display level..
Even after calibration its still way off (20%)..

i think you need to perform a "wipe on batt" in cwm maybe can help. Anyway i also discover that my tap below 4 buttons occasionally the light will be blinking on and off during at the standby mode, i belived this also can cus some batt drain off too. Anyway, most of the people are concerning about batt duration especially devise such as non-detachable batt. For me, i use my tap outside most of the time especially during business trip hangging in the train station or airport.... Well, i think we appreciate the overcome team and the rest of you guys to test it out and gain feedback for improment.... cheerss... and Selamat Hari Raya to all muslim people ya.
did you try the tweaks here re: Battery Recalibration and Reconditioning…
http://p1000.teamovercome.net/?page_id=68
and do note that:
battery wipe by itself would not immediately “improve” your battery life. IN FACT, during the first charge cycle after a battery wipe, you might notice a slightly less than optimal battery-life! This is because, the stats have to be rebuilt, which is why after a couple of FULL charge cycles after the battery wipe, when the stats are properly “repopulated”, which is when you’ll see the difference.

yes, i have did that after going through the forum, and today is a second day after the wipe, but i would recognized that if you put the tab in Normal stanby mode, the batt will drop about 1% in about 4hrs since i have started to monitor this morning... well, i will continue to monitor aand post it again. thanks for your advise.
my one on overcome 3.3.1 seems to last at least 1 hr when the battery notification show 0!!!
I have tested my second days after batt wipe, it seem that if we put at standby mode the batt really better then earlier versions, i can notice that last night was 26% at 2.30am and this morning waikup at 7.15am, the batt indicate 24%. (Note : my wifi is on, except BT and GPS is off).
My conclusion for now is that the OC 3.1 batt life is ok and even better when it was in standby mode, however whenever any application for example browsing internet or starting reading news, the batt will start to drain off like 1% every 3min (my estimation point of view).
Hope the OC team can help to improve from here OR the nature of this OC 3.1 is normal on this circumstanses. Cheerssss....

[Q] [i9000] Team ICSSGS RC3.1 - Battery Life

Hello everyone!
I've installed few days ago the onecosmic's ROM RC3.1, beatiful, perfect, smooth bla bla.
The problem is: i'm seeing so many post of people saying that with full charge, phone can stay alive for an average of 1 day- 1 day and an half (24-36h) with a normal use.
My phone can last 13-14h staying most of the time in standby and it's the 5th cycle so should be "stabilized" now. 1st cycle was awful, 8h (didn't expect anything else), then things got better but i've reached this cap of 14h.
I've tried Fugu kernel at first but i didn't get much improvement so i switched to paul kernel and changed modem too (jvk->jvt).
Still can't reach the dreamed 24-36h, i mean, i don't care about having 2 days of battery life, i would like to use the phone without having to charge it in the middle of the day.
btw nstools installed and set Deep Idle on, which seems to works just fine for me with the paul kernel.
(can't post outside link -.-)
nstools stats:
h*tp://i44.tinypic.com/6duvzb.png
does these stats means it's working?
i'll post also CPUspy stats:
h*tp://i43.tinypic.com/35052qf.png
is it everything ok here?
On standby there's no battery drain effect now, but when i'm using it, i get 1% down every 1-2 min.
What do you guys suggest? do i need to try other kernels/modems? shoud i try to flash again?
p.s. on 2.3.5 stock i used to have 24-36h but there's no way i'm going back to GB, i love ICS.
I used to have 24h of battery life, but I don't know what happened, after a week or so now my phone is draining 20% every hour, dead by noon...
Tried NStools with undervolt, and it didn't change anything.
It's now an useless piece of junk... this is retarded, either i will try reinstalling ICS or im going back to GB.

maybe your problem is caused by an app, or more than one, which are using push notification, you sould try uninstalling some...
Tried undervolt too, i got maybe an hour more.
Update: i just flashed again with RC3,1 and paul kernel. Situation seems a little better, gonna update again after few battery cycles.
What thing is in the battery status menu?
If it is media server: settings-->apps-->all--> Mediastorage-->force stop(dont wipe data)

sure! with the new paul kernel the battery life is better! amd now i'm trying the last glitch...my phone seems to work better...!i will hope to have also a good battery life without hard drain (with didle support maybe it's possible!)
actually, there was a lot of "Android OS" usage, maybe something went wrong from the beginning, the phone wasn't going to deep sleep state when put on stan-by and use more cpu than necessary when active, that must have been the main issue.
As i said, installed RC3.1 again this morning now everything is gooood
Lots of facebook, whatsapp, camera and 1 call, still have 67%. When put on standby battery almost doens't drop at all (checked on battery graph).
I think it's solved
I've the same problem. my battery life sucks...
Now my question. Where can I find/download the paul kernel? I#ll re-flash it too .
And my second question, do the "devil - der teufel" kernel do a great job too?

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.

I have flashed RC3.1 yesterday, it lasted for 8 hours. I was using it heavily to check all the features, syncing the contacts etc. I have drained the battery fully now. Will charge it upto 100% and see how long it last now with normal usage.

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.

Battery Drain
hello everyone - I have been searching a lot abou this i9000 battery drain on ICS. I am using ICS and Devil karnel and battery lasts for around 11-12hrs. My usage is pretty normal. I dont use phone for most of the time but still it reaches to 12hrs mark. If I check battery stats then Android OS and Display (brightness is very low) are consuming most of the battery.
Please let me know if there are any ROM Tweeks or any other way to increase battery time. Or I will have to go back to GB because I hate charing battery two times a day.
Thank you.

[Tips] Improve Battery Life on cm10.1 Rom

My phone (galaxy mini) has battery life issue on cm10.1 rom, which is that battery drains very very fast. for example, i just do texting, browsing, tweeting and lil bit gaming, my phone battery lasts only for 4 hours, even less. i ve used tweaks, scripts, apps to improve the battery life.
I found these all work:
No. 1: calibrate your battery
drain your battery till your phone shut down, charge it till is full (wait till no charging sign on the battery icon - ignore charged notification on lockscreen).
do it couple of times.
No. 2:
a. change this line in build.prop
from
ro.ril.disable.power.collapse=0
Click to expand...
Click to collapse
to
ro.ril.disable.power.collapse=1
Click to expand...
Click to collapse
b. change egl.cfg
from
0 0 android
0 1 adreno200
Click to expand...
Click to collapse
to
0 0 adreno200
Click to expand...
Click to collapse
No. 3:
odex the rom (partially, so you are able to change phone's theme).
Follow these steps:
1. move these apps : contacts,
mms, phone, settings and systemui, from /system to another folder (use non-default launcher).
2. run the app (attached on this thread forum.xda-developers.com/showthread.php?t=2156287 ).
3. ur phone will automatically reboot.
4. move back contacts,
mms, phone, settings and systemui to the /system after odex has finished.
No. 4: recalibrate battery using rom
(use lastest erikcas' cm10.1 rom or goldchang's cm10)
it happens times ago.
so today i backed up the rom. then i installed goldchang's cm10 (my phone lasts up to 12 hours in standar usage when i was using this rom), i used this rom for couple of hours, and i backed it up. then i did factory reset-wipe cache partition-wipe dalvik cache and battery stats. and i restored rohan's rom. i dont know how, but now my battery life gets much much longer. it's been almost 6 hours (when im typing this thread), my battery has 29% remaining. for me it's superr.

hopefully those work on ur phone.
credits belong to
rohan , erikcas and devs for awesome rom.
no.2 point a to dheeraj (dhlalit11) for build.prop tweaks thread.
no.2 point b to clayteau.
no.3 to nixoman for odex thread.
and goldchang.
g'day and salaam.

the trick is with battery stats wipe and not with goldchangs rom...that's quick calibration..
some times old battery data might cause excessive drain..so wipe battery stats also while installing a new rom...it wont effect much but u never know..i recently saw an article about this in google tech page somewhere
but mostly the drain might due to an app, so see if the app activity is still running in background even after u killed it..if such an app exists then uninstall it u will get more battery life..
actually, i wiped battery stats after fully charged maany times and freeze some apps too, those things didn't work.
well, like i mentioned before, i have no idea how it happens, but my battery life gets much longer, for real, yay.
yeah, but what if the 'background' app is must not be stopped i.e launcher, we shouldn't stop it right?
we talking about 1200mah baterry, righT? manufacture said it last for 6 hours of Edge, that means heavy usage, right? so, if you are using your phone a lot, that means 6 hours of internet, mms and calling, it wont get any over 6hours...for me, facebook offiiciall app and whatsapp drain battery like hell...so i delete fb, but whatsapp is must for me...same result...so no matter you do, even with deep sleep, its 6 hours of heavy usage...i also have Nokia e7, same capacity of battery, and same durability, 6 hours of heavy usage, except on nokia e7 battery goes quickly for its screen , not background app...android consume a lot of battery, its a fact, so there is no a chance that someone else calibration or tweaks can result better battery capacity...but, if you set your CPU mhz at normal level (600-248 at ondemand), you can get a good battery backup...is that cpu level its ok for you, than its ok..but running cm10.1 with that cpu level for anything else but music and opera mini, its useless...so, what ever you do, its still 1200mah capacity, remember that...your usage, is something else
take a look at my first post, my phone had has three 'phases':
1. rohan's rom before (poor battery)
2. goldchang's (awesome battery)
3. rohan's after (awesome battery, yay!)
my phone usage on those three is nearly same, even the number three i suppose is the heaviest because i haven't charge my phone till now (i charge whenever battery came to 4-1%, it's long enough from my last charging). take a look at ss.
here's a thread about battery calibration
http://forum.xda-developers.com/showthread.php?t=1821870
*there's a link tells that battery calibration is a myth, IDK
About Battery Callibration, I dont think it increases battery life. It just resets the .bin file stats to show the battery indicator (in status bar) correctly. Do it once after you flash a new ROM (after charging 100% + 15-30 minutes) & then calibrate either from CWM by resetting battery stats/ using the app in playstore called battery callibration . It will then show the correct battery indications.
Many people dont do this and then they complain about battery dropping suddenly but it is actually not dropping. Its just the indicator which is wrong.

so is that means when indicator says phone is fully charged, the fact is not full charged?

Only the first time you flash a new ROM. Just let that notification come and then charge an extra 15-30 minutes & then callibrate once. Thats more than enough.
Re: [Tips] Prolong Battery Life on Rohan007's cm10.1 rom
I tested battery with Extremely Heavy and Harsh usage. And it lasted for 1:40 mins.
What was the test?
Running whatever the phone could.
So what was running?
1. Wifi(scanning mode, not connected to any wifi)
2. Bluetooth (scanning mode all the time not just 120sec; not paired, connected with any device)
3. GPS with Gps essentials app: struggling to lock GPS for 15 min, then locked for 10min, then again lost the lock... in short it was alternating in lock and unlocked states with time gap of 10-15 min as I was indoor)
4. Video Playback: Alternating Background/foreground playback of 320x240 to 640x480 res Videos with mx player
5. Screen brightness 100%, wake lock on, speaker volume 50%, cpu usage 600mhz ondemand
6. camera on all the time(+ small 10min video recording), with gps essentials app
7. Egprs: 20min surfing, sync on all the time(no social apps)
8. May be I forgot something.
Specs:
Device: galaxy mini
ROM: CM7 autoradio v8 or CM10.1 (forgot)
Battery: A newly purchased genuine 15 day used battery.
Note:
Test date: 6-feb-2013
Everything I mentioned was CONSTANT, SIMULTANEOUS On for all the test period.
Battery was calibrated which was showing true stats.
I do not have any battery usage (right now searching for any screeshot if i captured, mistakenly )
phew, so harsh test. how did it managed. In normal scenario the battery only last for 4-5hrs with no gps, wifi, Bluetooth, camera or 3g on. Maybe I will switch to Stock rom for long lasting battery usage as battery charging even when the phone is off is totaly, wierd.
Like post? Just Thanks me in ur hearts, no need to "presss" thanks.

extremely dangerous, do not try this at home .
i thought GB stock rom has a poor battery life, even for standard usage.

Thought not, I'm switching to GB only for pure/normal usage with no root, no data hogging apps Just for few calls, one hour egprs browsing, enjoy local videos and music(no streaming).

Fast battery consumption

Hello people.. I am having problems with my nook color again ... I have paranoid android 2.99 (using android 4.1.2) and in the first time after I have installed the rom, my battery was draining an acceptable percent of 3-4% per day (24 hours-idle mode). After I have played with it a bit and install some applications and games, the battery loses 12% per day I would like to know what background application drains the most of the battery, though I have uninstalled most of the applications.. Is there a way to check how much of the battery each application consumes? I want to uninstall it immediately. I have tried Cpu Spy as I read on other discussions, but it is irrelevant to my needs.
Thank you

That's pretty normal for the first few recharges after flashing. Let your Nook completely discharge and charge it all the way back up. By the third time it should be back to normal. You can find out what applications are using the battery under Settings, Applications, Battery Use.
Hi, thank you for the reply. There have been more than 3 recharges since installing this ROM. The battery life was longer right after installing the ROM but I don't know what have I done wrong that the battery life is shorter now(with the same ROM). I tried going to settings but there I have an option apps that lists all my applications and I cant see the battery consumption of the applications...thank you
Another thing that might work is toning down your prossecor. I have my max at 800mhz, and I get a few more hours of life, and you don't notice it to much.

Try using BetterBatteryStats and see what is keeping your device from going into deep sleep.

Thank you for the answers .. I wiped out the cache and the Dalvik cache and everything seems back to normal now
frostysnowman3567, Thank you .. I will try and use Setcpu to get a proper use of the processor... even set it at the minimum of 300 mhz when deep sleep is active.
Fire Ball, I will install that application, sounds useful thanks
was runnig it with cm7 with excellent battery live several days, now trying cm10, battery drains way faster, it feels like you can watch it drain. anyone else experiencing the same and having a solution?
