When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?

If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.
on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.
plzz someone reply.

Yes.
You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.
and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time
Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?
hi
it only been happening since start of the weekend, ill turn my phone off before bed wake up and my battery stats are wiped...i dont no whether its because my phone has basically been on standby and i havent used it much?

the phone isnt modified in any way (i,e rooted,cwm)
any help would be appreciated :good:
bump...
please move to help section
Hey guys.
My first post ever, so please bare with me.
I made a big mistake updating to 4.4.2 coz I've had only problems since that. I have a rooted SM-N9005 with a Danish carrier. I have read and read and read for at fix, but can't seem. to find on. . My problem is this.. I can have a fully charged battery, unplug the phone and can, by using the power button, turn the phone off and on again. BUT if I pull the battery out and insert it again after 10 sec, then the phone doesn't turn on. It only turns if it gets the power cord in again. That's the first problem.
The second on is the battery drain. I have done a dalvik clean, cache partition clean, factory reset, soft reset, hard reset, uinstalled pretty much every app that I have... nothing helps. I even bought a new battery.
Can you guys help me or guide me in the right direction on what to do??
Thank you in advance
Can't help with your first problem, sorry.
How quickly is your battery draining? Can you post a screenshot? And more details - custom/stock ROM, kernel etc.
You can try and pin down what is the biggest battery hog with Better Battery Stats.

Hey B3311
Thanks for the reply
A couple of screen shots. Even when using BBS I haven't been able to pin point the exact cut print
Dreadful drain indeed....
Can you see what's under "partial wakelocks" and "kernel wakelocks" in BBS?
You had wifi on but still huge drain when the screen was off and the phone was asleep, hence I'm thinking wakelock - something is stopping your phone from sleeping. But you need BBS or Wake Lock Detector to pin it down.
They can be a ***** to find, but can be zapped.

Hey Jdomadia
Pretty much everything is off.. data . GPS.. Bluetooth and so on.. I'm still wondering if my problem is due to the power button issue that I'm having
Hi Bro i had the same problem the source of it is the developper option just desable them from settings and every thing will be normal again i hope that works for you too
Hey Abdel310
That never cross my mind. Better Google how to disable them once I have enabled them. Bro, I tried everything so I'm gonna try this straight away!!
Just did it, and man if that helps I'll be the happiest camper you'll ever see
i had the same problem i left my phone fully charged and i go to sleep and at the morning i found it off and 0 % battery and no apps runnig just try it and full charg it and it will not drain battery at lest in the sleep mode
Sadly disabling the developer option didn't fix the problem..
it still drain battery in sleep mode ?
the latest screen shots from better battery stats. I can't find any partial wake lock that seems to cause the drain
It's starting to sound more like a malfunctioning battery itself. Especially considering your first issue.
Have you tried a different battery?
Also try it without the SIMcard. A malfunctioning SIM can also cause these issues. (Happened to me back on 4.3. Drained 12%/h, not a single wakelock and 98% deep sleep. No SIM, no drain. New SIM fixed it.)

So here is the latest update.. I found out that even when the phone is off, like shut down the phone drains the battery. had to phone to a complete charge, shut off the phone and left it alone.. during the night the battery was drained... and it's a brand new battery

If you can get your hands on another battery, just to test, try that (could be you bought a bummer battery) Do you have any friends with Note 3 you can swap batteries with just to see what it does?
Hey Burtcom
tanks for the reply. I can't believe that it's the battery, without knowing for sure. I'm still wondering if my problem is due to the power button issue.. as I mentioned, if I remove a fully charged battery from the phone and reinsert it, then the phone won't turn on. it will only turn on with a power cord.
Now my phone drains the battery even when the phone is off.. like completely turn off.
Hi Guys, i just got this phone 2 days back. i should really mention that its an wonderful device, great display, fluid usage, everything is quite fine except battery. The very first night i had left my phone for rest by switching off WiFi and Data connection with more than 35%, next morning i was in surprise, phone was not turning on at all, then after charging it for few min it booted back with 5% charging. the same thing happened last night as well, i had purposefully charger it to more than 40% and wholla in the morning it was just 5% remaining.
i'm on stock COS rom with no changes.
So you good people, i really ask u to help me,
Is it happening with other phones as well?
should i get a replacement as i still have return period?
Thanks in advance
Nope. Mine is perfect. What have you tried to find the cause for battery drain? ??

Thanks for your time.
May i know whats battery drop in idle mode, probably over night in your phone?
i have only installed only Whatsapp as of now and no other apps apart from the stock ones. when i check battery info everything seems to be okay with the apps apart from the constant battery decline in the graph.
I have reset my phone and trying to identify the cause of the battery drain.
please do share if you have any apps or tips to identify the cause.
Thanks again
Hi,
Not sure if this is in the right section so admin please feel free to move.
Ive googled my problem and had a bit of a read but dont really get any solutions.
Ive noticed a serious battery drain since upgrading to 6.0.1 - maybe it happened on the previous version however ive just seemed to have noticed it more since i did the update.
My battery doesnt last very long. It will show 100% in the morning. If i dont use it, it can go down to about 80% within an hour or so. If i do use it then im using apps like gmail, whatsapp / sms, short phone calls, some other apps but im not on them for very long. I normally close all apps that are running in the background.
This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

Factory reset might help a lot.
Dont really wanna have to do a factory reset if i can help it.
I forgot to mention i also cleared the cache in boot mode

I had same battery drain issues when i updated from lollipop to Marshmallow but after doing factory reset everything is better then lollipop and doze feature in 6.0.1 works very well. I leave my phone at night about 9 hours and not drain even 2% battery and i got 5 hours scrern on time .
try factory reset+wipe cache from recovery and use atleast 3 days to doze feature work properly.if you have same drain issue then it's a bad battery.this is the only solution so far.
Battery pull?
