My new Note 4 is losing 10 to 15% battery life while its shut off over night. I've changed batteries with no luck. I've even exchanged the phone for a new one and still the same problem. I've rooted and used different rooms. Even ones that claim better battery life, same problem. I eventually unrooted it back to stock and that seemed to do the trick, but what fun is an unrooted phone? Lol. So I rooted it again, added a rom and now it's back to draining while shut off. Does anyone know any answers on what I might be doing wrong? I'd sure appreciate any help I can get.
Download better battery stats and post a screen shot of the alarms/wake locks.

It probably won't show nothing because phone is turned off.
I suspect that factory rom writes battery level status before shuts down and set to that value after restart. Custom roms may actually read value reported by battery. I noticed couple of times on my note that phone turned off while having about 5-7% battery reserve and show 0% after immediate restart. It is possibly battery calibration problem but doesn't bother me since very rarely I let my phone go below 20% battery level.

There is a root required battery calibrator app in the play store as well.
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
But my guess is something you have installed on the phone is keeping it up even when you turn it off.
Have you side loaded any pirated apks? there is a known virus that will do just that.
Also are you sure you got clean root/bootloader unlock? You may want to start over and do that process again.

Best way to check is shut down phone when charged fully and pull battery for over 30 sec. Then install it and don't turn on till a few hours later and see if battery still drains.

i was hoping this option would resolve my Note 4's "battery-draining-while-the-phone-is-powered-off" issue, but sadly it hasn't. I returned to Stock Odin, re-rooted, charged my Note 4 to 100% and overnight with the power-off, the battery lost 22% of capacity. any suggestions? if not, going to ship to Samsung who i suspect will punt back to me because it's been rooted. thanks.
EDIT: i purchased a new battery so it's not battery related. new batteries work fine in my wife's Note 4.

No help here...........I got tired of the battery drain from all the custom ROM's I tried (just about all of them) and am now back to JH7, getting almost 32 hours before being drained. I have done some tweaking to it, got the GPS working great and everything works whereas with some of the ROM's something had to be sacrificed.

Did you flash with 100% battery and then calibrate your battery afterward?
No it wasn't at 100%... And no I didn't calibrate the battery... Was I supposed to??

It's certainly worth a shot. I had the same thing happen to me once a while ago and it seriously extended my battery. There's some threads here that describe the process which essentially involves discharging and charging your phone off and on and deleting the battery stats through CWM.
I always flash a ROM with a battery showing 100% and I typically net pretty good battery life doing it this way.

You can calibrate at any time. No need to reflash.
Maybe before you reflash, please wipe of the factory settings and partition and also the Dalvik cache and battery stats in "Advanced" settings using your Clockwork.
Ok I'm trying one of those recalibrating methods. Maybe I really should've read everything before I flashed... but there was sooooooo many stuff to read and watch...
When you say "advanced" in clockwork, thats the rom manager correct? when i look through it it says advanced mode for premium users only... is that the right app?

I'm sorry but now that I search through the forum I see that its a common problem and it's something I missed. I'm totally new to android (smartphones period) phones and flashing and stuff. Thanks for all the helpful tips!
One question though. When you delete the batterystats.bin file, does it get recreated at a later point or never again?

It gets recreated, yes.
Have to remember as well that each user may see different results with the same Rom. Kernels. Modems, Roms perform differently from one device to another based on a multitude of factors. After you have done the basic steps to try to stabilize battery drain, I would then begin by experimenting with different kernels and modems.
Idle drain is the test I normally use after ensuring proper battery readings, sensor usage and app CPU behavior. Many times simply flashing to another kernel shows immediate results.

I've yet to learn about flashing kernels. I'm now running perception 10.2
Sent from my SGH-I897 using XDA App
Download the sgs kernel flasher app from market. Go to kernel thread off your choice in captivate development an download kernel, placing the file on your internal sd card. Run the app which is poetry self explanatory.
Definitely try a different kernal or modem. Generally, you can find feedback in the rom thread about what kernal or modem gives the best battery life.
I haven't used Assonance but I had to flash the firebird 2 kernal to get good battery life with Perception 10.2. Keep trying.

Try to completely empty the battery by rebooting after your phone shuts down because of low battery. Keep rebooting it after it shuts down again till it doesn't want to boot anymore. Till the battery is completely empty.
Then Charge it again and leave it on the charger for more then 20 hours.
Don't know if it's gonna work but give it a try
EDIT: Q? are you using a custom ROM ??
Ok I'll give it a try, thank you. I have this problem since i flashed a modaco firmware and wiped my battery cache via cwm. Anyone else having those issues?

Turn OFF phone
Charge till it says it is FULL

Sorry, should have given more detail. That 48 hours is with general browsing and social networking with a fair bit of video recording and camera use. No 3G though. All data was over WiFi.
Certainly not just stand-by though.

No full power use of the processor i understand
i thought i had the problem too with the MDC fear 5.3 but it just jumped from 98% to 100 after 10 minutes so its probably a mistake which solved itselve if you charge it long enough.

Didn't work for me, i did it exactly this way, charged it for about 10 hours, booted in recovery, wiped the battery stats and it stills shows 97% when i boot it. However, it's not a disastrous failure, i can live with it and hopefully it gets fixed sometime.
Finally, i found the solution for me. After i reflashed the stock rom, where this problem doesn't occur, i flashed a modaco rom again WITHOUT WIPING THE BATTERY STATS. Now it's all working fine, i charged my phone to 100% a few minutes ago. Hope it will help some of the people, who are still having problems.
Does kernel version has anything to do with this issue?
Don't think so, i tried the stock, Paul's kernel from FR12 and the EternityProject Kernels 1.3 and 1.4, it was all the same until i tried reflashing without wiping battery stats. For the record, i flashed the new TK-Rom V 0.6 with the EternityProject Kernel 1.4.
Hi,
I recently updated my phone to JVQ but now i'm having a battery drain. The cause (i think) is the high percentage of the android-system. By now its 29% and that's alot. I already deleted the programe software-updater so that can't be the trouble maker anymore. Does someone has a fix for this?

Yeah....let your battery go completely dead, then try turning on to make sure its dead
Leave your phone off and then plug in charger until its full, then unplug and plug in again to make sure its full
Repeat these steps 2-3 times and it should be all fixed for you
Also....using titanium backup, freeze the program called "Samsung account" that's another culprit in the "battery drain crisis"

Guys, my sister has had her I9000 for a good few months now and everything was fine until recently.
She phoned me (knowing I like my phones) saying her battery life had become really poor over a couple days.
So I took the phone off her and updated it with Kies, so now it's running the latest Kies Gingerbread for that phone. I should point out it is not rooted, completely stock.
I noticed some crummy looking app's like Android Anti-Virus and Task Killer so removed them hoping one of them was acting the goat.......everything seemed to be going good until yesterday and she charged the phone all night until 8am and when it came to around 2pm the phone was flashing up with low battery alert. She said she had used twitter a little and browsed on the internet a while.
I have told her to get CPU Spy and look if the phone is going into deep sleep, yesterday it had 0% deep sleep and today it is saying 70% deep sleep even though the battery only lasted 6 hours before low battery warning...
Any ideas what I can do to track down where the problem is? Would she see better battery with ICS or a custom GB ROM?
Mine did this on stock ROM luckily mine lagged when I went into battery use it was Samsung app push update service or something like that but thanks to the lag it showed sleep lock before it shower that service I uninstalled then it could go back into deep sleep

it will root your device and install clockwork mod, should fix the battery issues though. Try flashing the CF root kernel via odin. Theres a tutorial in the thread.

ya i've done it.Only few apps running.When my screen is on while typing a text i lost 2% so quickly.
i'll use this method
Battery not "calibrated" - we don't have real facts on this one yet, so consider this our best guess
Explanation: It is said that the battery looses track of it's capacity (or rather the phone does) so it needs calibration.
Fix #1: Always flash new ROM:s with full battery.
Fix #2: Follow the guide TechnicR have on recal:
· Turn phone off and charge till full
· Start recovery and wipe battery stats
· Reboot and start the phone
· Use it heavily until it turns of by itself
· Connect charger and turn on the phone and wait until fully charged
i'll get back to you once i do these things..Let see if it fix my problem. If its not fixing means which rom should i use it for better battery life ???
