Hi Bro,
2 days ago i try to root my tabs then install battery booster, and now i'm never got this issue again, but i don't know after today, so let's monitoring.
BR

its been 2 days since i also install battery booster, the battery issue is gone. but now i am wondering is this the best solution using an apk for this issue, or maybe i should use my warranty card from samsung to get a new battery instead...

I reset my battery history using the clock work mod recovery, since then I havent had this problem.

this does not happen to my Euro Tab.

okay so i was planning to use my warranty card but the term and condition for warranty state that battery is not on the list

Low battery life

Hello,
Since I bought my cell (about 1 year ago) I've been experiencing low battery life. I've used different roms, tried about almost everything to decrease battery consumption (2g, no wi-fi, etc) but it still lasts about max 8h (moderate usage). While using continously it lasts max 2-3h. So is this normal, what could I possibly do about it or should I just buy a new battery?
Currently running Nova Hd RC 21-39 with Supernova pre RC-3 kernel.

No that's no where near normal. Could you get a screen shot the battery usage ?

Not sure if you ment those stats, just tell me if it are not the right stats.
Translation:

Wi-fi

Screen on
Charging

Other stats are:
Screen - 92% (on automatic though) Wi-fi - 7%
Mobile stand-by - 3%
Yes, it makes 102% kinda weird ^^

don't sorry about screen percentage, its heaps inaccurate.
Could you install system panel from the market and tell me what the cpu's are doing on idle?

Nothing really special, it varies tho sometimes it goes to max instantly and drops back within 2s

I'm pretty sure the battery if screwed. You can pick one up off eBay for a steal.

Your cpu is at 50% all the time, how is that nothing special?
Install os monitor and check whats using the cpu.

Looked at OS monitor and only thing that consumed cpu is android system (5%) and system (2%)
Sent from my LG-P990 using XDA

I'm running CM7.2 RC1
Worked fine for a while and now th phone looses 10% per hour (idle). Checked OS monitor and System panel but there is nothing eating CPU or something that shouldn't run.
Only thing that changed between the two phone states (fine / annoying as hell) is some experimenting with GetRIL. So I re-installed the RIL (v20l) that worked fine before but it didn't help.
Also I have two batteries. The original LG and the Andida, both give crappy results. Think I'm going to try to go back to the stock ROM, see if it helps.

i just did that. having two batteries will probably confuse the calibration unless u calibrated them the same way. either way, from what im guessing, not fully discharging the batt will mess the readings as 1 constant battery ?

According to my earlier measurements the Andida is also about 1500 mAh in real life. So it shouldn't differ much. From what I read clearing the battery stats doesn't do much, said some Google developer. I'm back to v20r now and it looks much better.
40% in 7 hours, before it was 10% per hour idle.
Today it was even better, ~30% in 8 hours. This looks more like I was used to.

Battery drain with the screen off

I've noticed that my phone spends much battery with the screen off, i think its te Modem what do you think?
Im on cm9 nightlies with semaphore kernel.
this was with almost all the time screen off and 2G, if its fault of the modem recommend me a battery saver modem.

You can instal the Devil kernel and activate "Deep idle"

Also try JuiceDefender

Sorry Bit i use both deep idle and also juice defender, i really dont know what to do!

I'm going to say it's the kernel as I'm running the standard one that comes with Cyanogenmod 9 and I don't have this issue. Actually, my battery is above average.

There's a big issue with i9000's running hot and having high drain at the moment. I'm not sure what has caused it on mine. It seemed to happen after I upgraded to CM9 but I have flashed back to 3 different varieties of stock ROM/kernel and same story. Gets really really warm when under load and battery drains at the rate of around 20% an hour when the screen is off, phone is in airplane mode and NOTHING is running (i.e. in deep sleep).
At a real loss as to what to do about it, I've seen a thread about 500 posts long on the official Android forums with i9000 and i9100 users all expressing their frustration over this.

In your battery stats what is showing high drain? Also instal better battery stats and run it for a while to drill down what is causing problem

Hey, appreciate you are well intentioned but have been through all possible diagnostic steps and all documentation/suggestions I can find online. I am an experienced IT pro and have tried EVERYTHING that has been suggested ANYWHERE by ANYONE and there is no fix.
Screen is showing the most, followed by MediaServer then Apollo player. Problem is the battery drains when all those things are killed (i.e nothing is running phone is in deep sleep). This happens overnight when nothing is runnning at all. The battery stats do not change. The processor does not show anything as being used.
Many people have already been through the diagnostic steps and there is simply no answer.
Refer this thread:
http://forum.xda-developers.com/showthread.php?t=1635614
There is a reported bug on the official android site as well but I'm on my work PC and don't have my history from home to drag it up again.
Basically symptoms are
- Battery drains exceedingly quickly ~15% when idling and 25% per hour when in use.
- All diagnostic tools show nothing running or using your battery or CPU
- Phone is warmer than usual in any state (i.e. idling/charging/under load)
- Most folk I've seen with the issue have flashed to CM9 at some point but that is not a consistent truth.

In your first post, i saw your "señal de red móvil", is very poor. Have one or two little line green ( best signal ).
As is the signal coverage where you are? The signal is good or poor?
and when you get with wi-fi on, the battery drains very fast.
Sorry for my poor english.

its poor man, thats why i want a battery saver modem, and the wifi battery drain its horrible, please help me!

Did you have this problem from the beggining? I am using Dark Knight 3 ics, and for many months everything was okay. One day, i had battery drain. Even after a reboot, the drain was there. I reinstalled and it works fine again

guys, now i have a almost one full day with normal use, i dont know if i can get better results or whatever, but im happy with this result, i've done it downgrading to GB and i'm happy with it, but i would prefer to stay in ICS, but well im not bad with GB.

Is samsung gonna fix the bug on 4.0.4 or what?

Hi fellas,
Im just wondering is there any fix on 4.0.4?
I mean the battery issues and overheated device? Cuz im thinking of rooting my device in the end to just giving it a try. But it will void the warrany for sure. So, just wanna know if any of ya all just happen to know if thers any fix coming out real soon. So that i can wait.
It seems that my device is now consider as useless piece of s...t just wondering why would i want to use this so called smartphone if i cant use live wallpaper, push email, screen brightness for my luvly super amoled screen and so on if it drains the battery like thirsty camel. It just a thought tho.... U guy might be thinking the same. So, i did all the the things like calibrating the batt, installed cpuspy, take out the batt on plane mode trick and so on.. , yes it did help the device to sleep. But it drains when im using it for 3 hrs with a lil bit of surfing, emails and sketching .it just doesnt make any sense at all.
Dont you guy think that samsung is trying to lure us to change to s3? Or note 2? Well it did cross my mind. Lol. i might not consider samsung in the near future. I guess,htc x one is my choice cuz it offers 6hrs batt. Hehehe

dude battery life with screen on in clean condition, without fancy stuff is only 3.5 hours. Some with other kernels/roms have reported 4 or even 5 hours, but that's really max
Sent from my GT-N7000 using Tapatalk 2

It is a power hungry phone,
Large screen - If you've got your brightness all the way up will use more power
Live Wallpaper - Pretty - Battery drainer
Games - Power hungry
etc
As mentioned - you cannot expect to use a phone like this for 8/9/10 hours with constant use, At 3 hours constant use, screen on, probs wi-fi / data, Gaming, listening to music.. you will see the battery drain quicker..
Could alsways pick up a one of those larger Mugen Power Batteries / second stock battery if your usage demands it... I've got two stock batteries but the actual amount of times I've need to call on the backup one is rare, I keep it handy as both me and my girlfriend have GNote's.

Thx for replying guys,
Maybe i left something earlier on. 3 hrs of moderate usage..as in moderate guys. Ddnt hppn to me on gb. I had at least 5 hrs max on gb without turning off thos fancy stuffs.Thats the main issue. So ics is the culprit.

Well then there are ways to analyse, as posted above for abnomal battery drain in deepsleep, when not using phone. That is one option.
Best guess is to do a full clean install of 404 by going to gb through pc odin, root it, get on cwm recovery, wipe cache, dalvik cache, backup efs, save pictures on computer, backup messages with app from play, sync contacts to gmail and then backbin recovery format everything in mounts, except efs,ofcourse.
Then phone wont boot, but is truly squicky clean. Then go into download mode and flash throught oc odin a stock 404 rom.
Do not recover apps/data, just manually redownload them.
Dont ever on unsafe kernel from stock ics do these steps. EVER!
Then download cwm. zip which is temp and flash speedmod k3-11 from recovery. I bet your battery life will improve and you will get 4 hours screen on time. Not as good as on gb,but still better then now
there are threads for every single step here, start in dr ketans thread in sticky section of development. Then tool thread of dr ketan in general section.
disclaimer: you can and will lose data and possibly warrantee

But yeah, thnx for the info again, but thats the problem bazz, i just need to know bout the fix. Tried to call samsung support but they are not too sure bout it. Cuz im willing to wait for the fix but not too long. Currently i hv dis dilemma of maybe selling the phone with stock rom, and buy another phone
or rooting this phone which im not too sure how to go about.

Use the BetterBatteryStats to see what`s going on behind and CPU spy to see what is the Mhz you Note is at.
On 4.0.3 ICS I find my battery lasts longer than on GB.. Strange!

i dont have problems on 4.0.4 with draining or heating...
maybe there is some app .... e-mail push 5 min......

Same here. GNote with ICS 4.0.3 has a worse battery life compared to GB, not to mentioned occasional freeze and unresponsive screen, also broken wifi-direct. Pretty disappointed with Samsung in the software department. Jelly Bean was already out and OTA for ICS 4.0.4 for both my GNote and GTab 7.7 not yet available in my country. Come on Samsung, these products is a premium products, pls provide a premium software update. Pfffttt...

If you think your battery life used to be so much better with gb why don't you go back to gb? No obligation to use ics. I use 4.0.4 with goku kernel and battery life is at least as good as it was under gb. 4 - 5 hours of usage, lasts a full working day.

1.Charge battery with phone turned on until galaxy is fully charged
2.UnplugTurn off phone and charge for one hour
3.UnplugTurn galaxy on, wait 3 minutesTurn off phone and charge for one hour
4.Reboot
And now my batt is coming back to its normal performance... I get around 11hrs 45 min on standby and at least 6hrs of moderate usage.... Thank god. Hopefully it will last..

I feel like having the same autonomy like GB since I went on 404.

lol email push 5 min, dont think you know push technology...
Anyways, those six hours is not with screen on all the time.
Doing the steps I mentioned however will force a full clean install. Then test without restoring apps battery, you will be amazed. Then install in batches or one by bone to eliminate possible culprit that impacts battery life.
Perhaps even better to go to samsung/shop where you bought and ask them to fix it If it is battery they will catch it and replace Less risk for you

Obtained this info from another thread:
about the alarm_rtc wakelock;
install terminal emulator from market and type these commands:
- su ( followed by ENTER )
- dumpsys alarm ( followed by ENTER )
it will dump some info on your screen
scroll upwards a bit and search for 'Alarm Stats'
here you can find the processes that keep your phone from deep sleep

Depends on what you did during that period.. If the processor was running at MAX frequency the entire time, yes thus might be normal.. Also as I notice from the screenshot, the screen is always in in that time frame.. So you deduce from this

No. It's broken. You should send it to me.

Hi,
Thats an abnormal drain. Try restarting your phone and seeing if the problem persists. Also note that the ROM you are using is still under testing and not a finished product so might experience some difficulties. Consider shifting to a more stable ROM if problem persists.
Having said that, battery drain will depend quite a lot on what apps you have running in the background and your settings.
Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.
