[Verizon Galaxy Note 4 Q&A, Help & Troubleshooting] JOSHSKORN:
I wanted to create a separate and focused topic on the ZeroLemon battery and how it behaves with the Verizon Retail Note 4.

What we know, is that batteries with a capacity different from stock (3220 mAh), do not seem to calibrate on the Retail Note 4 as-is. In particular, the ZeroLemon, which has a capacity of 10,000 mAh and is also a TriCell battery. I do not know the reason behind it, but I've heard through many sources that a TriCell battery will not read correctly with the SM-N910V.

However, there is a supposed "Fix" out there for the ZeroLemon battery, in the form of a kernel file that you have to flash. Here's the problem, though. You can't flash it. Why? By default, your SM-N910V is locked by default. That is, you can't change the ROM, and you can't flash any kernels or root your phone.

BUT...a couple of people have managed to unlock the Retail Note 4. There are many posts on how to do this. It's a fairly long process, kind of complicated and must be done with care. Look at this tutorial on how to unlock and root your phone, just remember to not get too excited and skip steps, or it won't work or you may bootloop or even brick your phone. You have been warned.

Once you manage to unlock your phone and permanently root it, find a ROM that you like, flash it and learn it. Make sure you take a ROM from this forum, and it's compatible with the SM-N910V.

Now, here are the meat and potatoes of this post. Take a look at this thread. ([TW/CM][Emotion Kernel][SM-N910-F-G-P-T-V][1-JAN-2016][5.1.1]Emotroid Team). In the Downloads section, there are different kernels. Some of them labeled ZeroLemon, some not. You obviously want the ZeroLemon ones. Upon further examination, you'll see that there is no listing for the SM-910V.

The ROM that I'm using, is the Kyubi Note5 Port The Last (Light Debloated). Flashing this ROM will change your phone's Device Name (or Model Name) in your About Phone area of your Settings from SM-N910V to SM-N920F.

That said, you want to download the Emotion Kernel version for the SM-N910F. Go to the Downloads section of the Emotion Kernel OP, maneuver around their website, select Note 4, then 5.1.1. You'll see a file containing the label SM-N910F. Download it. DO NOT ATTEMPT TO FLASH IT. It will fail. I made this mistake. If you want to try and flash it, go ahead. It's not going to work.

To get this file to flash correctly, you have to edit it. it's actually pretty easy to do, and you can extract and edit it however you'd like. Just be sure that when you zip it back up, that the directory structure is correct. Basically, this is what you do:

Find these two lines in the file updater-script (in

Emotion-TW-nightly-r23-RC1-SM-N910F_ZEROLEMON\META-INF\com\google\android

):

getprop("ro.product.device") == "[B][U]trlte[/U][/B]" ||
getprop("ro.build.product") == "[B][U]trlte[/U][/B]" ||

Replace with:

getprop("ro.product.device") == "[B][U]trltevzw[/U][/B]" ||
getprop("ro.build.product") == "[B][U]trltevzw[/U][/B]" ||

Now zip it back up. The Kernel file should flash. HOWEVER, you will notice that your SIM card will no longer be detected. What I did, was I flashed the DataFix file that was suggested to flash after installing the ROM that I was using and this fixed my SIM Card issue.

Now, will this work with any other ROM? Will it work with Android 6.0 ROMs like CM13? Honestly, I do not know the answer to this. If you look through the Emotion Kernel thread, there's a r24 stable beta release out. I'm not sure what the difference is, if the kernel I flashed is compatible with Android 6.0 or not, but the title of the thread does state 5.1.1.

As a result, my phone is draining at the same rate. HOWEVER, I did notice that when I got to about 32%, I put my phone away for an hour, and all the sudden it jumped up to 67%. It's hard to say if I bumped it or not, that is, if my loose case caused my battery to disconnect and my phone to reboot. I am currently going on 27 1/2 hours, and am on 50% battery. This is my first discharge after a full charge, but I did only charge it for about 30 minutes after the solid green indicator light turned on. When it dies, which will probably be tomorrow night, I'll charge it for 12 hours.

Here's the short version of this bloated post:

Unlock/Root your phone

Install a 5.1.1 ROM (i.e. Kyubi Note5 Port) (I do not know if this will work with CM13/Android 6.0 but if you're willing to try it, do it and report back your findings)

Download the Kernel for the SM-N910F

Extract, edit and zip (see above)

Download the US Variants Datafix (I used the Multisystem one)

Flash the Kernel, then the DataFix

Follow through with the charging instructions that came with the ZeroLemon manual.

So this is where I'm at right now. I'm seeing something a little different, it seems a little inconsistent and I don't know of the 1% problem as of yet since I'm not there, but I will post back when I do. I also did not rename the file when I zipped it back up but I wouldn't know if it'd make a difference or not. Maybe?

If you attempt to try this, please post back your results.
