I used GSAM to try to figure out what was causing my high battery drain, but it was never one particular app or service (other than Google Play Services, that is). I would get high values for display, even though the screen was off the entire time. I'd go from charged to 80% in 1 afternoon with no usage or screen-on time.

Look at this post in the 15.1 thread. The author uses an Automate pattern to shut off wi-fi when the screen is off. This seemed to fix the problem for them and it has for me as well.

Error in flashing

This is likely because my tablet is in some particular mode, not because this ROM isn't working.

I got this tablet from Costco and it was in the retail mode (i.e. apps can be installed but the device will be reset to the original state regularly). I failed to install the Android 6 & 7 images from updato via Odin (it stopped near the end of the process).

I flashed TWRP 3. via Odin, copied this ROM zip file to `/sdcard/`, installed it and these are the errors:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details ...
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
...done
Unable to mount storage
Failed to mount '/data' (Invalid argument)
...
assert failed: samsung.verify_trustzone("TZ.BF.3.0.3-00054", ...) == "1"
Does anybody know how to fix these issues?

Coming from stock rom, you have to format data on twrp to remove stock encryption. Not just wipe, but format, by typing yes when prompted.

Note: This will delete all your data and internal storage.

This is what I just did twice: Wipe | Format Data | Type yes and click the Tick key, then the screen showed:
Updating partition details...
Failed to mount '/system' (Invalid argument)
...done
Full SELinux support is present.
...
assert failed: samsung.verify_trustzone("...", ...) == "1"
Updater process ended with ERROR: 7
Error installing zip flle '/sdard/lineage-...zip'
Updating partition details...
Failed to mount '/system' (Invalid argument)
...done
Did I miss anything?

Which twrp version are you using?

Use latest from here:

That's what I'm using (twrp-3.2.3-0-gts210vewifi.img.tar).

Would you mind attaching here a screenshot of the error in twrp?

I can see myself in the pictures below
p1.jpg: type yes, then click Tick to format the partitions
p2.jpg: format completed
p3.jpg: choose the zip file to install
IMG_20190120_140323.jpg: installation error message

I think the partion to mount /system to doesn't exist (that might be resulted from the failed flashing of Samsung image via Odin).

My two other suggestions:

Reflash latest stock firmware and repeat process
Make sure your download file is not corrupted.

I already downloaded different stock firmware.They are all unzippable and pass the check by Odin. So I guess they are ok.

Not sure what you mean... The firmware files should be unzipped though. The file has to be with a .tar.md5 extension for odin use.

And a ps: you did unlock the bootloader right?

Same at my side for the high battery drain.
What I saw is that the Deep Sleep Mode is never activated (checked with CPU Spy).
The below solution is working for me (readed in a different discussion):
Toggling of the Flight / Airplane Mode.
I did it in this way:
1. Activating of Airplane Mode
2. Restarting of tablet
3. Deactivating of Airplane Mode
4. To check the Deep Sleep Mode: Resetting of CPU Spy log
5. Wait few minutes to check if Deep Sleep Mode is working

This ^

Seems to work in los 15.1 too.

Tagging @LuK1337 maybe you would appreciate to know? Perhaps helpful to investigate? Maybe you already knew this, but just in case. Sorry to bother you!

I always went back and forth from stock to los because of bad battery life. And this seems a nice workaround atm.

Well, I updated two of my three T813s with the latest build (16 Jan) and the Camera issues are fixed. I did a clean flash on one, dirty flash on the other (both coming from LOS 15). No issues on either.

Recent Apps

I just did a full wipe and install of this with opengapps and Magisk. When I hit the "recent apps" button it says that are no recent items. Any ideas?

I'll try wiping and reloading again to check it out.

EDIT: I did an "upgrade install" over the top of my first install and the problem is gone…

 

[OhioYJ]

The latest build the kernel is no longer permissive! Kind of looking like this is definitely ready to go official whenever Lineage finally takes 16 official. Everything is still running solid.

As for battery life / deep sleep issue, I've been using NapTime By Francisco Franco. My wife's tablet last night had 4 hours of SOT with the last charge being 6 days ago, still at 42%, my tablet has still been managing 6-7 hours of SOT. I kill everything when the screen is off, Wifi / location, etc, but it's made a big difference from before. Even my son's tablet is going over a week (sometimes he forgets about it) without needing to be charged.

I also get functioning deep sleep with lineage-16.0-20190206
