I had random reboots with 17.1 but them were unrelated to battery level. I rarely let my charge drop below 50%. Recently went back to 16.0. Haven't used it enough yet but battery is 38% as I type this and no problems.

Nice! Well, if/when you get the random reboots, the fix I posted should work for you. It works on all three of mine.
But that's awesome. You might have the last functional SM-T713 on the planet, lol

Here's the builds I'm using, I think the 16.x builds are even still getting security updates.

I flashed the 3/28 build. It has the January patch. That's current enough for me.Here's the builds I'm using, I think the 16.x builds are even still getting security updates.

I see an update dated April 3rd. Anyone know if that has the March security patch? The March 28 update still had the January patch.

The Feb2022 patches were merged on Feb24, just the security string wasn't bumped. The Mar2022 patches were submitted on Mar25/26 but still not merged.
So the February patch is in the latest build but not identified in the build info?
That's what it look like to me, of course I have no proof of this other than what's visible in the link I posted.
That's definitely a thing. I've seen it happen several times with unofficial builds over the years.
Anyone know how we could manually check? Is there a file we could check the creation date of or something?
I have experienced WiFi suddenly turning off several times in the week since my 713 has been back on 16.0. It's always come right back on by itself until today. WiFi wouldn't stay on so I had to restart that tablet. I had forgotten about this little 16.0 quirk. On the plus side it haven't had any random reboots!
Ok, so it's not just me! I was starting to think I was crazy, lol.
My internet is being fixed as we speak, I'll get back to troubleshooting when I know it's not my infrastructure that's the problem.
Anything interesting in the logs when the wifi cuts out?
Nothing in the router log. Don't know where to look in tablet if that's what you meant. I have experienced this with almost every version of LineageOS but I think maybe 17.1 was better than 16.0.
Ok, good to know. If you have root (or don't mind using ADB to enable it) please check logcat on the tablet, this is the app I like. I'll be doing the same and report back.
Ok, I finally managed to capture logs from when the WiFi cut out (on 17.1, still working on getting a logcat from 16), and there's lots of errors, but I'm not sure what the culprit is. I'm going to keep Googling errors from the log, but if anyone wants to take a look and see if they can spot the culprit, it would be greatly appreciated.
I've attached the log file.

You can use adb
Logcat command-line tool | Android Studio | Android Developers
Logcat is a command-line tool that dumps a log of system messages, including stack traces, when the device throws an error and sends messages that you have written from your app with the Log class.

LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
Instructions :
- Download the latest build and gapps
- Reboot to recovery
- Flash the latest build and gapps
- Reboot
- Builds : https://download.lineageos.org/gts28vewifi
- Root addon : https://download.lineageos.org/extras
- Google Apps : https://wiki.lineageos.org/gapps.html
- DO NOT Report bugs if you're running a custom kernel or you installed Xposed
- Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
- If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
- If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Last Updated 2019-03-0213I have updated the kernel in today's build with a new WiFi driver and several hundred cve. It should not be necessary to disable WiFi anymore while sleeping.6Ok, I also faced the challenge to update my bootloader in order to be able to update LineageOS to the latest versions and I am a Windows user and I did not want to do a clean install of first the Samsung ROM and then LineageOS, thereby losing my data. So I read a lot of posts here in the forum and used the following solution to update my Tab S2:
- Download Odin from https://samsungodin.com/download/Odin3 v3.12.3.zip
- Download the latest Samsung firmware from https://www.sammobile.com/samsung/galaxy-tab-s2/firmware/SM-T713/
- Extract the .md5 file contained in the downloaded zip. You can use 7Zip for this. It can handle tar files as well, which is needed for the later steps.
- Rename the file, so that it gets the extension .tar instead of .md5
- Extract the files sbl1.mbn, aboot.mbn, rpm.mbn, tz.mbn, hyp.mbn, sec.dat, keymaster.mbn, cmnlib.mbn, adspso.bin, modem.bin and NON-HLOS.bin from the tar file and place them in any folder on your disk
- Use 7Zip (or another program that can create tar files) to create a T713.tar file containing the files extracted in the last step
- Turn off your Tab S2. Enter download mode by pressing Power+Volume Down+Home at the same time. Confirm that you want to update your system by pressing Volume Up.
- Connect the Tab S2 to your PC with the USB cable. I'd suggest to not connect any other Android device at the same time now.
- Run Odin as Administrator
- Make sure the ID:COM field changes to blue, which indicates your device got detected
- Click on the AP button and select the T713.tar file we created above
- Click Start to flash the file. The Tab S2 should reboot at the end of the process.
Afterwards you should be able to install the newer LineageOS versions (but no longer the older ones).
Of course I take no responsibility if you brick your phone or nuke the world using the steps above
.5
The latest current available update includes new kernel.
To verify, the new kernel is 3.10.108 in Settings->About.
