I had to kick of kingroot because it was causing *a lot* of CPU utilization on the Max2 with god knows what. (in fact, I didn't kick it off, I just went into recovery and flashed the newest firmware again, it was really dug in deeply in there - it is possible to remove it though but I just didn't wanna bother) From googling around regarding 6.0.1 exploits I couldn't find anything that interesting. I wonder what they used. My guess is they were rowhammering. Explains why the unlocking took a while, too. Don't install apps you don't trust, folks!

I read the datasheet of the charging chip in the Max2, charging is toggleable and it does expose that functionality in it's registers, I'd have to look into the linux drivers (which are open source and I think even mainlined) to see in what way you can access it. You're out of luck without root though, which of course isn't surprising. The charging chip takes the battery out of the path when it's above a specific voltage though and supplies the system directly from the USB port, so a full battery stops charging for a long time when the tablet keeps being connected to USB. You can set what the chip considers full so in a roundabout way you could stop charging that way, too. I guess this is standard for most of these chips today, still was nice to seen it written in black and white.

Results with CPU governors were somewhat of a let-down really. You (naturally, I guess) get more responsiveness with a higher base clock, but of course at cost of battery. Other schedulers are more aggressive which is good for background tasks and drawing but really doesn't help when you just start using the screen. A lot worse for the battery are screen updates really, if you keep those down and keep away from A2 mode, you get out as much of the device as you can expect, so ssh'ing writing text in emacs etc. is fine, really. The usual tips of not installing a lot of apps etc. also apply.

Getting past the shock of the somewhat slow SoC it really is decent as terminal. I enjoy it. Another small trick you can apply (if you have the hardware that supports it) is to use bluetooth thetering to your smartphone and use the internet/networking that way. Not as fast but a lot easier on the battery.

EDIT: Re: Termux. Base16 Greyscale is not really a good selection as it sets the main color to a shade of grey instead of black. You can edit color.properties in the ~/.termux subfolder directly and make your own. I left everything at default besides foreground color and background color. I don't know if I did something wrong but every time I edited that file it ended with just setting everything black on a new session. Adding termux-reload-settings for local sessions into ~/.bashrc fixed that. You can also change colors and fonts on the fly with that command. Termux also accepts .otf fonts, you just have to rename them to font.ttf. Setting TERMTYPE to linux is also a bad idea, because it stops mouse emulation from working and using the stylus in mc, emacs and such is just too nice. Maybe all of this is common knowledge already, but for me it was new and maybe it helps somebody. With this, it's possible to create commands in emacs via shell to switch the font on the fly. I wonder if it supports non-monospaced fonts which I like to use for org mode. Colors correctly configured, it is not necessary to use any contrast optimization etc. the software on the tablet offers. Very thin fonts which usually don't look that nice on screens look very nice on the Max2.
