[Q] [ASK] HElp to find out what causing this battery drain

hi all..
2 weeks ago I finally bought my very first android based HH, GNOTE...currently I'm running on ICS LPF Taiwan unroot, and very love it. one of my concern on this ICS, is the battery drain so much, considering it just sit on my pocket.
i have CPU Spy and BBS Installed, and found that it just Deep Sleep 48% and 200MHz 37 %. Kernel Wakelock is "multipdp" 25% Power Manager Services 21,2% and secril_fd-interface 19.25.
could you please tell me what causing this battery drain so much..?

The best thing that you could do is do a Factory Reset, but with all the bricking problems it's highly discouraged. I don't recognise the processes, but you should make sure that you deleted all the apps you never use, since one of then could be causing the problems you have.

After upgrading to German ICS, also had problems with wakelocks (phone never sleeped)
Done this (posted on XDA somewhere) and it worked:
Turn Flight Mode ON
Turn Off the Phone
Take out the battery for 30 secs
Plug battery back
Turn on the phone
Wait until all is loaded and turn off Flight Mode.
Also, always disconnect from the charger with screen ON and unlocked.
After using this 2 metods, never had a wakelock again (multipdp etc)

thanks a lot for both of you....
will try these steps.....and will comeback with the result....

i've tried those two methods, and still got multipdp issue...
i also have disabled the fast dormancy with *#9900# command, but still no effect, ...could you please or someone give another way to solve this..

Stop syncing from your gmail account.
The big one is unplugging charger with screen on.

thanks for your answer for my question...
regarding that did you mean that i have to stop receiving email on my Galaxy Note..?? for me that's really important since i bought my note to support my daily job...
is it the main cause..? if yes, i think i should buy another battery as a way out.

I also have encountered the same problem with my galaxy note after the stock ics update in India.
I have checked out the earlier posts on the same issue..
Some users had the problems of deep sleep and some others had other problems..bt as far i have been able to understand this problem...it is associated with those apps which we often use..for eg i had been using apex launcher for so long...and it used to suck my phones battery like hell also coz of the widgets and the other things that it use.
So what i did was a simple factory reset and a data wipe and didn't install the apex launcher again.
I let my phones battery drain completely and charged it till 100% and simply rebooted it and removed the battery too. And its working good now.
Those things which suckedy battery included android system and display...i could do any thing about display but i force stopped may process of android system and results are good.
One more reason for battery drain could be that when we go backs from the apps on stock ics on galaxy note..the apps do not get closed comletely like stock web browser which works in the background too..so might be other reason for so.
Don not install those apps which u dont use often coz they might work in background add unnecessorily suck ur bettery.
Try the battery pull off trick it really works for majority of users.
Force close those apps and processes which u feel unnecessory.
Those whose claim ics doesnt work smooth on their note they pls go the develpers option in settings and enable the force GPU rendering option then it will work smooth like anything...
One more thing which u may already know about galaxy note ics is that now it runs all the tablet apps on ur note! Thats pretty amazing coz u need not root it or do anything...for me it worked with the apps like...adobe idea, adobe photoshop touch and all other adobe apps and some other tablet apps..download these apps directly from 4shared..so cheers!!!
Those who are not happy with their battery pls try factory reset and battery pull off trick...it worked for me and it might work for u too my friend...

if you are entering deep sleep at all then you aren't being affected by the bug where you have to make sure your screen is on and unlocked before pulling it off the charger.
i suffered from this bug after updating to ics lpy, but since following the guide above (flight mode, power down etc.) i've had no issues.
let your phone completely discharge, then turn it back ona dn make sure it turns off again. then fully charge it. i found this increased the accuracy of the battery a little, when i did it it dropped from 10% to 1% in around 20 mins, then i was able to use the phone for almost half an hour on 1% so obviously my battery stats weren't quite right.
if you've done a factory reset, and you're sure the phone is entering deep sleep ok, just go through a couple of complete charge/discharge cycles and see if that improves things

Analyzing is tought on android.
Printscreens of kernel wakelock and partial are better.
Partial is mostly what exactly is keeping awake
Try some of the suggestions from the numerious threads, state them here whicj didnt work and describe usage a little more detail, that way we arent shooting in the dark
Sent from my GT-N7000 using Tapatalk 2

i still got this issue regarding multipdp and secril_fd_interface....maybe it caused by unstable network or the fast dormancy stuff...
so i went to nearest samsung center and buy a spare battery... now i have no concern about this...but still keep on eye with l2_hsic...the flight mode on and restart will solve this issue..

I was having battery drain issues myself. Got tired of checking CPU Spy and BBS etc. Worried about bricking and wiping so I...
I rooted the phone.
Installed SpeedMod Kernel 3-3 via mobile odin that didnt really solve it.
I installed Abyss kernel. Wiped everything because its supposed to be a safe wipe kernel.
Then installed Criskelo rom
Then installed SpeedMod Kernel 3-3 again and everything was great with battery life.
You have to reinstall apps and setup your phone basically but its well worth it in my opinion. Now my only battery drain is me always messing with my phone.

I would stay away from telling people this is a safe thing to do in ICS, it's been proven many times it is not.
Maybe you have been lucky - so be thankful you're not using a paperweight...

@gayanaji - I use Criskelo's ROM and all the Samsung apps work fine. No probs here. Many of the custom ROMS are based on other Kernels that the Samsung apps do not work with. I am a bit new to this but I believe that is correct. Just make sure to use a Samsung app compatible Kernel if you decide to do it. Also another piece of advice before doing anything read a bunch to make sure you fully understand everything with regards to rooting, flashing custom ROMS etc.

New ICS UK official release battery drain

Manually upgraded over stock non rootable CarPhone Warehouse GB rom using PC Odin.
Im getting very bad batrery drain. On the stock GB rom my phone would easily last two days with moderate use. Now with the ICS rom its draining pretty fast. I took it off the charger approximately 1.5 hours ago and with little to no use Im already at 90%. Same stock settings and same apps. Only difference is I am now using Apex Launcher.
I noticed wifi constantly on even during deep sleep but i have now configured it to only be on while plugged in.
Ive pulled he battery out for a few minutes and that hasnt helped. One last thing im going to try is revert back to GB and then wipe, clear cache and upgrade again...
Any advice/help would be appreciated..

I´ve had the same wifi problem, german stock ICS though, weird enought it seems to happen just with my home´s router. I´ve checked in other places and all was fine. A couple of users here changed their routers seemed to solve the issue. See if this is of any help....

Yeah, i updated to the lpy ROM when it was released and found the lack of deep sleep issue causing a problem. The above fix sorted it and I've had no problems since, performance has been noticeably better and battery life has been just as good, if not slightly better, than under ginger bread

Takes longer to analyse bro.
In those 24 min abnormal battery drain?
Best to check battery percentages.
Next to these two apps you can check badassmonitor or equavalent, they have also good measuring for actual battery usage per app.
Analysing sucks thought, totally not user friendly.
Sent from my GT-N7000 using Tapatalk 2

I could be wrong but it seems as if my wifi is still constantly active...battery drain is pretty bad...i think im going to revert back to GB, perform a full wipe and cache cleane and re install...

I did an "factory data reset" before and straight after i upgraded to the official UK ICS.
I did read if you use the alarm clock, it keeps your phone awake, even after you disable it, other apps most likely do the same.
Below is a picture over night, I always manually enable/disable wifi/bluetooth/gps as have yet to find an app that works correctly.
John.

Yeah tipically you would be looking for the following:
If your device goes into deepsleep at all. (on battery that is)
You can check this with cpu spy.
If it doesnt check the kernel wakeloks (high level) and the partial wakeloks (zoomed into detail level, best level for troubleshooting).
Anything there that runs often and long is probably causing the deepsleep insomnia. I wish Android would be better in able to determine what really influences your phones battery.
Next to this, some apps you can change synch settings (within apps itself, e.g. facebook etc) Thats just a typical change. every sync uses energy, and wakes up device.
Another possible check is the power on of with airplane mode.
Another tip is unchecking the sounds when touching touchscreen (a bug from the old days of android, and they never fixed) this is a major wakelock causer and by default turned on.
I usually get 4~5 hours nonstop onscreen time after tweaking it (without setting to much stuff of, otherwise I could have gotten a normal phone lmao)

after factory reset and data wipe on your galaxy note please calibrate the battery both ways...horizontal and gyroscope.
This will definitely help your phone better monitor the battery and bring it to normal status..

I tried out the steps mentioned in above link and I think its working for me.
After upgrading my note to UK ICS release the battery is drainig like anything.
Its like 1% every minute .
After applying steps mentioned in the url its not draining that much. MAy after some more recharge cycles it will be more stable.

Is this hardware problem or rom or battery?

from past weeks my phone turned toooo slow and battery back up is also low
im on sgs2 v9 rom...
lemme explain from first...
after turing on my device..its runs with no lag for 40-60minutes...after that my phone turns too slow...no cpu setter app or nothing but it turns too slow...and only 4 to 5 apps installed
and battery is too low for me..i charge my phone for 3hours and i get only 5hours of backup(i will listen songs for 45minutes)
is this the problem of rom or hardware or my battery problem

It seems that there's lots of firmware load on your device, due to which battery is also wasting.
If phone was normal previously (before SGS2 v9), then surely it's software that's making your phone slow. Also, try wiping battery status in CWM recovery...
Hope this helps...

1. Wait till pop up command charged in Homescreen when u charge althought it's show 100%
2. What data connection u used HSDPA / 3G / EDGE ??
3. Check our Battery Physical there are inflate or not (put on flat place) if yes possibly our battery is leaks. if not just calibration your battery using 3rd app on playstore "battery calibration"

[Q] Battery Drain Problem

Hello guys I'm using a Galaxy Note GT N7000 on CM10.1 with NX Kernel
Recently I've been having a problem of battery drain. Even when I have put it in charging, the phone seems to have been draining out of it. I have tried to change the USB cable and the charger both, but still the problem persists. Does this mean that it'll get solved by a new battery? or there is some other issue causing this problem? Would wiping data cache or battery stats help? If so, I'd be glad for your help! If you require any more information, let me know. Thank you..

Witch nxkernel version are u on and have tried to full wipe everything and start from scratch the other thing is if its your battery you would probably be seeing stuff like your screen flickering and then the phone shuts down after reboot you find you have 1% battery that's the normal battery signs but other then that if it is dieing when charging you would have a huge drain and a fresh start could fix also you could check some battery stats see if something is staying active and could be an app doing this as well.

Hey I tried the following:
1. I tried a brand new battery but it didn't affect anything. I still tried a few more adapters and cables, nothing.
2. I did a full factory reset and the kernel was stock Cm kernel.
Still, the problem is persisting.
The NX Kernel that I WAS using, was version 1.3.9
What else can be the problem? Thanks in advance.

What governer have u set? And have u overclocked it?

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
