[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

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....

My note seems fine, have you tried the fix below.

Also try to find ways to analyse your battery usage, enough posts on that here
Cpuspy for deepsleep
Betterbatterystats for whats keeping phone awake
Android sucks in providing the info you really need up front.

so far i find the battery usage pretty good tho for wifi i had to change the router in order to connect

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.

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.

Battery discharging very quickly due to NO Deep Sleep

Hi,
I have been struggling with my battery lasting not more than 15 hours once it has been fully charged, so I decided to investigate and found out about the deep sleep issue that a lot of people are facing. I would be attaching screenshots of CPU spy and better battery stats.
Most details are in screenshots, i would be glad to provide whatever else might be required !
I hope someone would diagnose and help me resolve the issue.
Thanks in advance

Try the fix in the link, below, also turn of account auto syncing.
also you could try the free version of watchdog, to see which apps/processes are using your cpu.

I had applied this fix .. and i had managed to get healthy deep sleep upto 70% of time in last charge discharge cycle, but in this cycle the situation is back to old one .. i.e. No Deep Sleep .. and i dont know what caused it, this time around. This fix works but it might sudeenly stop working for no reason.
Thats why i am posting the screenshots so that people can look at them and suggest me what caused it ...

This will only work if the root the phone ... well i didnt want to do that for as long as possible.

Ok not sure about network locator, audio1 is I think about a bug of android which you can test by going to sounds and turning of the options in bottom. Especialky the sound when touchscreen is touched. Its sucks but should fix that.
Network thing, again not sure but could be fixed by turning off network dormancy in *#9900#.
Next to this test strange route: turn on airplane mode, turn off phone, pull battery for 30sec then tunr on phone and turn off airplane mode. Dont know why but some reported it works. Could work in your instance.
After this check this thread for addition tips http://forum.xda-developers.com/showthread.php?t=1649041

Hi everyone, pretty much my first post on here (second in all honesty) after reading hundreds of post into flashing/installing a custom ROM. I have always ran stock Samsung but with root, but I wanted more and I was fed up with Samsung and other rogue apps causing wakelocks (kind of became an OCD thing trying to get rid of them). Was determined not to ask for help with so many threads saying the same thing, so I just too the plunge and thought fk it yolo and flashed CM10 onto my device.
Didn't really have a clue what I was doing but got there eventually. Used CWM and downloaded what I thought was the only stable version of CM. I scared myself at first as it was just stuck on the CM boot, did a bit of reading and forgot to do the factory reset and wipe, did that and it all ran smoothly.
After spending hours of fiddling last night, I'm now wondering if it's worth getting CM 11 or should I stick to 10? I barely use anything complicated on my phone, solitaire is about the only game that I play, main thing is just battery life and phone functionality and internet browsing. Also are there any settings that I should be looking into?
I always ran one power guard with stock rom, but after installing it onto CM I found it was causing the phone to never enter deep sleep, uninstalled it and it's pretty good now, has anyone else experienced this? Does CM have pretty good built in battery management or should I look at getting some kind of task killer/battery management software? Couldn't risk leaving it unplugged last night to check battery as my gf needed the alarm for this morning and didn't want to risk it going flat in the night and getting an earfull from her
Thanks in advance for any tips/help.

First of all, you need to know what causes the battery drain in our smart phone no matter what ROM to are in.
They are mainly 3things. 1. Data usage, 2. Screen brightness and 3. GPS. So if you turn off data, turn the brightness down and turn off GPS. You will get pretty good battery performance in all Roms.

for the moment stay with stable CM10...in CM11 are a lot of bugs...today it's working nice...tomorrow it's unusable...
no need for 3rd party software for battery saving...all ROM's have ok battery life...but on stock is a noticeable difference.

Thanks for the replies. After leaving the phone idling for most of the morning I've noticed it's not sleeping. BBS is showing KWL is mdm_hsic_pm0
I've been trawling the net trying to figure out what it is, but everything I've read turns into a dead end. In the android battery stats it shows as Android OS. If i reboot the phone it seems to put it back in check, but obviously I don't want to be rebooting my phone all day!
Got very minimal apps running so it's really confuddling me.
Cheers in advance

Too Much overnight Drain

Guys i am experiencing A high amount of overnight battery drain.Almost 15% battery gets depleted every night.
I am on OOS beta 10 with Ex Kernel... Android OS always consumes 13-15% battery..
Can anyone provide a solution ?

It might be one of your apps that keeps waking the device overnight. Get a Wakelock detector, look for the app that might be the cause, uninstall it and see if it helps.
It might also be the kernel I'm not sure why but EX was draining a lot of battery for me as well, but it seems to be working just fine for others. So you might also want to switch to stock kernel for a bit and see how it goes
Also, a bit unrelated, but putting your phone on Airplane Mode while you're asleep can help also. (IF you don't get any important messages or calls overnight that is) I lose no more than 1-2% over 8 hours on Airplane Mode. Plus, it's good for your health as well.

I'm not quite sure about that. I only used EX once. Once you're certain that EX is whats causing the drain, you can go ahead and ask in the EX Thread. Hopefully someone will be able to point it out. And if you're not certain, I'd say flash stock back and get only the apps you really need and see if it still drains.
And if you're in to custom business, I'd suggest you try out Paranoid Android once as well, the new build is pretty solid and i'm getting a considerably better battery life than i did on OOS, both active and idle

I'm losing 1% per hour, it seems normal for this device.
I've tried factory reset and various kernels.
