Well for half of that, the spec you actual care about is battery life. The n30 has massive battery life. And for good modern non-curved lcd screens there’s never any backlight bleed anywhere. Yes, the blacks aren’t fully completely as black, but on a good modern lcd they’re very close to it, and in exchange you get all the screen advantages i listed above. Oled always has worse viewing angles, worse color accuracy, worse way of making the screen “dimmer” by using pwm rather than actually making the screen dim, etc.
Huh, definitionally it’s always a bad thing, i wonder why people around you use it that way
That’s similar but different in a lot of meaningful ways. Hydro pumping like that requires a relatively large body of water next to a large geographical height right nearby. This new system doesn’t require any water, and it uses a man made hole in the ground that’s already been created and which otherwise would be simply unused

This makes the most sense by far. Owners of a company always pay themselves a salary, and for a tech company with investors I’m sure these people were able to give themselves an extremely high salary. That salary money is legally their money forever no matter how crappy or failed the company’s output winds up being. Unless you can prove that an actual crime was committed to acquire that money, then it will remain legally theirs.
One thing to check when using a phone meant for a different region is to see if the phone has antennas for the spectrum that’s used in your country. Like if the cell service in your area uses frequency band A, B, and C, but the phone only has antennas for bands X, Y, and Z, then that phone won’t work in your country. The phone doesn’t have to have all the bands that your cell service provider uses, but the more bands match then the better your connection and coverage area will be.
But again it sounds like the spec you actually care about is battery length. If you get an oled phone with a medium capacity battery, then its usable battery length would be far surpassed by an lcd phone with a large capacity battery.
Obviously you should go with whatever you like, I’m just trying to help you figure out what are the actual features you care about.
