For the record, after a long time without this problem, it seems that today I have joined the "stuck battery indicator"club (on latest official).

I did a couple of things recently (i.e. in the past week): I replaced NFound's recovery with Oki's one, and tried to use Unofficial's kernel over Official. Everything should be back to "normal" today, though, and this is happening.

Update: a reboot or a cold boot didn't help, but plugging in the charger resulted in the indication going from 70% to 75% in less than 10 seconds; then I disconnected the charger, and subsequently the indication went back below 70%, and it's at 65% now.

Your battery problem is different from the "always being stuck at 50%" that others mentioned. Have you trying clearing the baterry stats? It's just deleting a system file, there are some apps that can do this for you.

Yes, I tried with this app after fully charging my phone, but my problem had seemed to go away when I charged my phone briefly and then let it discharge below 70%, so I don't know if the stats reset alone would have fixed the issue. I'll update my post if it happens again and I can try more things.

But also, I lose track of things a bit sometimes, and I didn't realize I am still running kernel 3.18.71-perf-gf94f7af25ec4, which I believe is the Schwifty kernel... as I said, I had played around a bit with recoveries and kernels, so I guess that's the big remaining difference between my phone and a standard official LineageOS.

I had installed it in the hope I'd get low persistence mode while remaining on official, though unfortunately it seems I still only get that if I echo 1 into the kernel parameter manually, and Daydream apps don't do it. Oh well. I can go back to the standard official kernel, although aside from this (one-off?) getting-stuck issue, I do seem to have nearly twice as much battery life as I had before (two days of standby instead of one, basically).

@Unjustified Dev: which thermal-engine binary are we using atm? Could the blurring issue be caused by that?
I see that the thermal-engine.conf and thermal-engine-vr.conf file is also changed correctly when entering daydream mode.

Edit: Litte update: I've seen in Stock ROM A2017GV1.3.0B03 there is a different thermal-engine binary and only one thermal-engine.conf file. However I don't understand how the switch between NORMAL and PERF profile is done.

Download the magisk module called props config or something of that nature. Then you need to change the fingerprint of the device to zte axon 7 within the list. It changes the fingerprint back to 7.1 nougat.

I appreciate your comment but this is honestly kicking my behind... At first I thought all I needed was busybox (by osmosis) and magisk would just work....that's a nope.... Then I downloaded the prop config and I'm reading the instructions over and over and nothing.... So i know there's a fingerprint for my phone and that's about it...

After you install the module and reboot, you have to run the commands in terminal (need to install it). Just follow the prompts.

Not sure if this is related to Lineage or just my crappy battery finally dying, but lately since I updated to a december version (a bit afterwards) but I began encountering INSANE backround battery drain, like 2 % per minute, in the backround, screen off or on, no apps using it, and clearing cache, restarting, charging to 100% etc doesn't fix it, charge overnight and it still drains insanely fast, any one have any ideas? Perhaps I can try leaving it in recovery to see if it drains that fast there too or something, apps like acubattery are confused and dont know what's up.

Did you install the unofficial?
The newest has a good battery consumption.

That's not the latest unofficial. That's the latest official.

Unofficial has updates that apparently help with battery life and is here:

http://files.nwwn.com/~unjust/

Latest build from dec 13th.

It requires a few steps to install and those steps are indicated in the thread, pages back. There is a script to run to move from official to unofficial.

On the latest unofficial and official work Verizon wireless I have volte without having to adjust anything. No magisk modules or anything else. Gps also locking very quickly less than 15 seconds out doors

See attached pictures. Note... I had to do a clean install to get things working... Ie delete data partition too I'm using the Oreo modem and v2 bootloader from original post.

Thanks.. And I see you don't have wifi calling provisioned. Can anyone confirm if Wifi Calling is working? Is the option even available?

I am very confident but not 100 percent sure that Verizion blocks wifi calling from phones that are not "certified" on their network based on imei. When I log into my Verizion account it says I'm using an unknown device.

And does not give me the option to enable wifi calling like I can on my wife's phone.

    To avoid more device bricks I have created very detailed, easy to follow instructions on how to update with minimal risk. The Bootstack in the OP is fine, but it doesn't support Emergency Download
    (EDL) mode. To avoid that I have gathered my custom B12 Bootstack, the TWRP Labs 1.3 and the Official LOS15.1 into an EDL package.


    BACKUP:

    if you want to keep your information, then you should do a backup of your data before continuing with this guide. You can use the file manager to move your Documents, Downloads, Music, Pictures, Videos, etc... from your internal storage to an external SD card. You can upload them to a cloud service such as Google Drive, One Drive, MEGA, DropBox, etc. Or use the USB connection to move your information to your PC.


    DEVICE UNLOCK:

    Unlocking your bootloader will trigger a factory reset, and will delete the internal storage along with all the information in your phone. If your Axon 7 bootloader is still locked, you have to follow this guide before proceeding to the rest of this guide. It works for Marshmallow and Nougat stock phones. Please use that thread to ask any question related to unlocking your device.


    INSTALLATION INSTRUCTIONS:


    WARNING, THIS GUIDE WILL WIPE ALL THE DATA IN YOUR DEVICE, INCLUDING THE INTERNAL STORAGE.
    IT REQUIRES YOUR DEVICE TO BE UNLOCKED, OTHERWISE YOUR DEVICE COULD BE BRICKED.
    !!! Whatever you do, it is at your own risk !!!
    ​

    In case you get stuck at any point in this guide, do not panic! There is a straightforward way to go back to stock. Just follow this Unbrick/Restore guide. I've tried to make things as easier as possible for everyone, specially newbies not used to deal with the Axon 7. So, I have created stable custom EDL packages. In order to reduce the risk and complexity, this one Stop ROM Shop performs all the following actions in a single flash:
    - installs my customized B12 Bootstack with EDL support
    - removes unlocked bootloader annoying warning message.
    - creates vendor partition.
    - installs TWRP Labs Mod 1.3 custom recovery
    - installs Official LOS15.1 ROM.
    - And the guide also helps you to format data and cache as f2fs in case you haven't done it already. It provides better battery, performance and extends the lifespan of the internal flash.

    STEPS

    1. Download and Unzip Axon7_LOS15.1_180925_B12Oki_TWRP_LABS1.3_FULL_EDL.zip to a folder in your computer, ensuring there are no errors. I have an A2017U, so the American modem is the package default. If you have an A2017 or A2017G just copy your modem firmware, from the corresponding provided modem subfolder, to the main folder. Just overwrite the default American modem file.
    2. Install MiFlash in your PC. It includes the Qualcomm Snapdragon SoC drivers, nonetheless you can always install the latest Qualcomm drivers.
    3. Enter EDL mode using one of the following options:
      • by pressing VolUp+VolDn+Power until the power led flashes briefly
      • Installing a terminal app and typing reboot edl at the app prompt.
      • connecting your phone to your PC and typing adb reboot edl at your computer's command prompt.
      • While your phone is completely off, press VolUp+VolDn while connecting your phone to your PC.
    4. If you haven't done yet, it's time to connect your phone to your computer.
    5. Open MiFlash in your computer.
    6. Click Browse button and select the folder you created with the firmware files in step 1.
    7. Click Refresh button and your device will appear listed as virtual COM port.
    8. Click Flash button and wait for a few minutes until it finishes. Note the bottom options are not applicable.
    9. Press VolUp+Power until the phone vibrates, then release both buttons and wait for TWRP to boot. Go to Reboot menu and keep pressed VolUp while tapping on DM-Verity ON until the phone vibrates. TWRP will restart.
    10. Go to Reboot menu and keep pressed VolUp while tapping on eMMC Write until the phone vibrates. TWRP will restart.
    11. Go to Advanced > Oki Labs menu and tap on Expand OS.
    12. To ensure everything is clean you should format the DATA partition, including internal storage. Go to main menu > settings and ensure "Use rm -rf instead of formatting" option is not selected. Then go to Wipe > Advanced Wipe, select Data partition and tap on Repair_or_Change_File_System button and then on Change_File_System button. Select F2FS and confirm action. Do the same to apply F2FS to the Cache Partition.
      NOTE: If you receive an error while formatting data, then go to Wipe > Advanced Wipe, select Data partition and tap on Repair_or_Change_File_System button and then on Change_File_System button. Format DATA as EXT4 first and, without leaving TWRP do it again as F2FS. That will fix the issue.
    13. Go to main menu and reboot system.

    Happy transition to Official LineageOS 15.1 Oreo. I have not included Google Apps and Magisk root since I just wanted to create a basic package with easy to follow instructions. If you are interested in expanding these instructions with GApps and Magisk just let me know.

    Jealous? No sir lol I'm just subscribing myself trying to catch up on things I just came back from a 21st birthday vacation. I do want to wait around and see what all issues people find that we couldn't. To be fair about battery life etc we didn't get the latest and greatest Oreo kernel source I received a bad beta with horrible overheating and battery life. I decompiled the dtb (device tree blob) from the prebuilt B12 kernel and that helped a lot as you can see no one hand is burning which is what I experienced before. Hopefully we can get everything solved and worked out eventually. I'm basically handing everything over to OP I'll continue to contribute though so I'll probably be getting back in touch with everyone on Hangouts soon to see if I can get some of the small necessary things out of the way like SELinux, offline charging mode, and the flip cover. At this point there's no reason to report anything previously reported, I've read every single comment and page just be patient

    I'm returning on the 16th got a promotion at my second job now I'm quitting my first. My plan is to start fresh on Pie using B32 kernel source and only modify it to work with Oreo camera. We gotta catch up in time for Q.

    Been seeing a bunch of fix battery percentage fixes. I said before ZTE oreo release appeared to scrap every change from stable N B32 to start fresh so I've been reverting pieces back to caf and b32 so I too have the battery profile working correctly in my latest kernel for 15.1. I was waiting around to see if ZTE released something new before I go and rewrite everything to be clean and less of a mess for something special.
