cm 7 on x10 battery life is horrible

I just recently flashed my phone to gingerbread 2.3.3 (cyanogenmod 7.0.3) and my battery life took a turn for the worst.
It used to last 24 hours or more, but now it only lasts 6-10. It even does it when the screen is off at night, ill wake up and turn it on and its dead.
Also if it helps my kernal is 2.6.29.6-b11.
(yes i am a noob)

there has been long discussions regarding problems with deep sleep (state when phone uses very little cpu when screen is off), this cud be a reason for ur bad battery life, also if ur using any custom kernels. to see if ur getting deep sleep, download an app called cpu spy from market and that tellse u how many hours deep sleep ur getting. or it cud be something else entirely, ive always stuck to a custom stock 2.1, so i cant really advise too much. search for deep sleep and follow ny instructions provided in those threads.
edit:
have a read thru this, it might possibly help u http://forum.xda-developers.com/showthread.php?t=1100786
edit again: try disabling automatic time and date set up to manual, as ive heard some people had some acces doing this, but as i sed have read thru that thread.

tried to use cpu spy but it FCs on my phone. unchecked auto date and time. im looking into other kernels that may yield better battery, havent found 1 yet that addresses deep sleep issue.
thanks for suggestion dude

Is it the new version? Cause my battery is good.

Hey, I've also heard of a bug in Google Maps. It is continuously running without letting the phone sleep. That's my problem with my battery right now.

seem to have fixed it, i turned auto date and time off and bluetooth and the battery lasts MUCH longer, 24hr plus!

Battery drain since latest update - solved!!!!!

Since the July 8.44.11 update my tablet in standby drains a good 3% or more per hour despite wifi off on screen off. This setting previously did not drain more than 1-2% overnight.
Nothing changed other than updating firmware.
Did some investigating to find the source of the drain.
See below as I think I found the source. Tablet was not getting into deep sleep.
OK I have solved this!!
I rooted the latest update and performed an experiment.
I used CPU spy to measure sleep.
With stock rooted the device was not going into deep sleep on 8.4.4.11
Then with titanium backup I froze the following to programs preventing them from running:
Mobile data and mobile network configuration.
Low and behold I now get deep sleep when testing this with CPU spy.
I suspect this wasnthe same source of battery drain in standby that occurred with the iconia tablet before a software update. Seems these programs are preventing deep sleep. Based on their description they seem designed for mms and sms.
Perhaps they were put there for the upcoming 3g enabled.models.

What do you have MobileDock Battery saving mode set to? Having this unchecked means your transformer is constantly spending power waiting for you to make a key stroke. If you have a newer keyboard or no keyboard you can check this and save that 2-3% per hour.
I do not see any additional power drain with the newer update.

I have observed increased battery usage in standby mode after the update.... an the average of 3% per hour. There has been no change in installed apps between the firmware update.
I rebooted the TF multiple times over the last few days without any improvement. Out of desperation, I plugged the TF to the recharge, and switch the tablet off. I let it charge up, and now the battery drain seemed to have reduced to pre-update rates. See screen capture of before, and after with the power-off-and-charge in the middle.
Observe also the CPU seems to be constantly awake even though the screen is off and in standby mode

2 observations I have made.
CPU spy shows I am not going into deep sleep
When I look at applications under the settings, under running services there is mobile data and mobile network configuration which to me seem more appropriate on a phone.
The iconia tab had issue with similar type process draining battery before an update. I wonder if the pre 8.4.4.11 update if those processes were running.

Experiencing the same, am on prime 1.6 (default kernel) and last night i removed charger when it was on 100%.
This morning battery was on 87%, this was after 6 hours. More then 2% per hour.
I have wifi setting on off when screens turns off.
When checking the applications in the battery info screen i saw "Maps" on top of the list. So when leaving to work i killed "Maps" hoping that it was the cause of the drain.
When returning home about 9 hours later battery was on 67%, so still about 2% per minute. That's even more then my SGS 2 with 3g on. So something is really wrong.

I saw an android bug listed, that after a reboot, the wifi sleep setting gets reset. Make sure that you select the wifi off when screen is off setting after rebooting.

I really want to help with this because there are a lot of people who are having these battery drain complaints and I just can't figure out the differences between my stock tablet and theirs. My tablet shows a very slow beautiful drain overnight last night.
My applications "All" shows the network and wireless applications also, however my running applications list is extremely small (Settings, The Weather Channel, ASUS Sync, com.asus.keyboard, Google Services, Music, Maps, MyNet, ASUS MyWater(asus live background)) so I can't say that network services are affecting my battery.

My TF has the same discharge profile as your device before the last 3.1x update. also, the CPU was never active in sleep mode. After the upgrade, the AWAKE bar is always active, and as you can see from my screenshot above, kills the battery during standby

Am trying this now, will report back. You did not charge it completely when turning it of as i understand from your capture.

Under google services, you might want to turn off picasa sync. I was told to do the same an I believed it has helped. Also try turning on airplane mode and see if it helps.
I have mostly unchecked all of the sync options which has helped in that my drain is like 2% overnight ~8hrs although I would like it to be even less .....

Click
Settings --> Accounts & sync --> [email protected]
Inside that folder you will have checkboxes for everything Google that can be synced. IMO Calendar, Contacts, and GMail are all that is needed to keep you up to date. You can manually sync everything in the settings menu of the program you use less frequently.

Tried to stop them via settings but they won't close.
Afraid u need to root.

Good find. Would help if you editted your original post with this solution. Hopefully this is fixed in 3.2.

So I guess this gives me another reason to root my tf101. Battery life is very important to me. This is the reason I got the tf101 with a dock so that I can get the full battery life of 16 hrs.

Thank you so much!
This is a great find. I just got my TF four days ago, so I haven't payed attention to battery usage, etc., but I performed these steps, so I hope to get maximum battery performance.
I also changed wireless settings to "turn off when screen is off".
This is why I love XDA.

Hmm, was looking around in Titanium - how do you freeze (prevent a prog from starting) an app?
Okay, found "deactivate" - this is the "freezer" ?

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.

Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.

Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.

Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??

You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.

Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?

Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.

I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note

I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

Battery drain while sleeping

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.

deep sleep!
Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )
http://forum.xda-developers.com/showthread.php?t=2357417
I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))

I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.

Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/

Android OS Wakelock killing the battery!

Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.

If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT
