IMO battery life is absolutely excellent, I brought it with me on a 2 week holiday last year, read for 30-90min almost every night and didn't need to charge it during the trip or worry about battery life.
If i haven't specifically agreed to, or asked for, promotional content I consider it unsolicited.
Unsolicited Ads are poison. I don't give two shits who's behind them, if you spew that shit in people faces, fuck you.
I'm using a Boox Leaf 2 myself, it's basically just an android tablet with an eink screen. I can load pretty much any eBook format, and you can put regular android apps from play store (or any other app store) on it as well if you want. And they have a microSD card slot available from the outside to expand storage.
All the hacks and mods people do to their kobo are not needed, because it's supported by default on my Leaf 2.
So it is actually just an advertisement...yuck 🤮
I tried blocking anything Amazon in my adguard home instance...holy shit that broke a lot of sites, I had to unblock it to have functional internet.
Because the EU is a diverse group of different interests, and while some intend to do good some are also fucking psychopaths.
This has some serious "idiocracy" vibes
It's also the most unlikely explanation of all, that phones brought in communicated with the ones in custody to reboot them. Even if it was a security feature to reboot phones under certain conditions, which is very likely TBH graphene OS does this, the best implementation isn't going to be relying on other phones randomly passing near by, it's going to be self-managed by the phone that reboots.
