I'm posting this for FYI purposes and to thank Trex888:

I was having this problem on TEKHD's Lollipop Rom also, so it isn't just MM Roms that are affected. I bought an 8000 mAh battery with back cover on ebay and it doesn't happen when using it. I can go all the way to 1% without a problem. Any time I use my OEM battery that came with the phone, my phone shuts down at about 24% charge and keeps power cycling. I can't even shut the phone off with the power button because it just turns itself back on and continuously power cycles. If I remove the battery and then put it back in, the phone will stay off. I thought my battery was bad and bought the 8000 mAh battery, which doesn't behave that way. Now, after seeing this thread, I am relieved to know someone found a "fix."

Needless to say, thank you very much for posting a working fix for this issue. I'm going to hit thanks in a few of your posts since I can only thank you once in the OP :)

Thanks again Trex888!

So did this method work to fix your old OEM battery or are you jumping the gun? Did you follow directions exactly? Is the wakelock app really necessary? Did you use the OEM battery for a few days to test this out?

Yes it did and no I didn't.
No I didn't.
No it isn't.
No I didn't. I switch back and forth depending on my daily needs.

To clarify... In my experience thus far, only the *#0228# was needed to recalibrate battery. The rest seems to me to be a placebo. The only thing I did was *#0228# and then charge the battery, run it down, and charge. I did this three times. That's all I did.

I suggest that people also state which custom rom they are using if they're not using a completely stock rom. I was using TEKXodus v7.4 5.1.1 when I tried this fix and it worked for me. No 2 roms, phones, or batteries are the same. Electronic components have "tolerances." Electronics is not an "exact science" due to tolerances.

I know lot of users facing this issue after marshmallow update so i decide to made this thread.
I have n910t and i have multiple batteries but phone everytime shutdowns at 15% or 20% after. Updated to marshmallow i did everything i downloaded battery calibration app from playstore but didn't work.
So i figured out how to fix and clear current wrong battery calibration status without root and my phone doesn't shut down at 15 or 20% anymore.

1,open dialer and dial *#0228#
2,after dialing *#0228# the battery status menu will popup.
3,hit ( quick start ) at bottom of the screen in red color
4,hit ( yes ) and go to settings/battery and disable fast charging for 1 charge only.
5,power off the phone and charge to 100%.
6,turn on the phone and if it shows 97,98,99 plug in charger again and charge to 100%.
7,once it charge to 100% unplug charger and this will create new battery calibration status automatically.now you can enable fast charge again.
8, Next go to play store and download wakelock power app and install it. Open the app and hit (PARTIAL WAKE LOCK) as in screenshot below.
This app will help the cpu to run much more efficient and smoother and also prevent device from over heating and this app does not require root access.

Download wakelock power app link below.

THIS METOHOD WORKS ONLY WITH STOCK OFFICIAL FIRMWARE IF YOU ARE RUNNING AOSP ROMS/CYANOGENMOD ROMS/NOTE7 ROMS/S7EDGE ROMS/ OR OTHER PORTED ROMS DIALING *#0228# MAY NOT WORK.
HIT THANKS IF THIS WORKS FOR YOU:good:

6,turn on the phone and if it shows 97,98,99 plug in charger again and charge to 100%.
7,once it charge to 100% unplug charger and this will create new battery calibration status automatically.now you can enable fast charge again.


In step 6.....if the phone does show 97,98 or 99..... are we to switch it off and charge again up to 100% or can we just charge it to 100% at that very same moment while the phone is on????

And for comparisions sake what usage time are yous having on your note 4's.
Mine on full charge (100%)
My estimated usasge time remaining says: 11hour 40minutes.
I have an Note 4 910C
Android Version 6.0.1

After dialing this code you must disable fast charging ang turn off phone and charge atleast 3hours
If it It it shows 100% after reboot then no need to plug in charger again.

At step 5, my phone charge up to 65% and stopped. It will not increase no matter how long it is plugged in. Do I power on and charge the phone again?

This pic is for POC (proof of concept) that this does work (screens hot taken at 9% battery):

This pic is to show that a ported Note 7 TW Marshmellow rom is installed:

5c9f1f649a0f5bc110f6721d08324458.jpg

NOTE: The model number is being misreported because I hadn't fixed it yet (simple build.prop edit).

The only thing I did was dial *#0228# in the dialer and charge the battery while turned on. I did not turn off the phone at all through 3 charge cycles. I probably just got lucky.

Be aware if you have xposed installed or running cyanogenmod/s7/note7/ based rom it will not work.

    I am running a debloated rom, do you happen to know what system apps need to be in place to do this?
    Some examples I see are,....bluetoothtest.apk, factorycameraFB.apk.

    Well, the little zip i made is simple, it removes from system/bin and xbin all the binaries which contain the "log" letters, so it removes from the system the capability of taking also logcats i suppose, but you can gain a little more battery. Then, if you need logcats you have to reflash the full system of yours. I am not responsible if you do damage. Here it is. I can share only what i've done to my Nexus 5 already posted on XDA, so i don't have to remake the same posts again. Anyway, basicly, try a baseband/radio modem which is more battery friendly than your latest, if it is possible, underclock your device CPU to <1 Ghz (my friend did so also) and use some good governor (you Samsung owner have a bunch of them soooo damn good at battery, i use for my Nexus 5 the blu_active one, but try others like nightmare and such). Well, have a look and see if you can improve also your battery

    I hope i don't go too OT here, i don't own a Note 4, but my friend asked me to do that for him. These are screens from his Note 4 Snapdragon, he says he uses Nameless ROM with AEL kernel and after tweaking a little, after calibration and some kernel settings, he has obtained this pretty awesome battery life

    MAN! 9+hours of Screen on time?:confused: that is redicolous i barely got 5 hours in my entire life with note 4 what exactly tweaking you did I'll be appreciated if you share with us .
