That should work for media files at least, but I believe they’ll also need Plex pass to be able to download anything.

Absolutely, that is definitely preferred when possible!

Things like turning off wifi and/or turning on airplane mode can make a big difference (when you’re not needing connectivity of course) The cell modem can really eat away battery life if you have a poor signal. And for my pixel tablet, turning off wifi means the battery can last for a couple weeks instead of a couple days. Heck, turning it off if you won’t be using it for more than a few hours can help too.

It’s weird, a little quirky, and can be a unpredictable at times. It all adds to charm though and I love it.
