As a phone repair tech, Samsung phones are some of the easiest to repair. Especially for batteries or (if you can get Samsung OEM parts) screens.
I highly recommend you take a look at installing the new battery yourself if you're able to be precise with a screwdriver. All it takes is the aforementioned screwdriver, a hair dryer/heat gun, and an old credit card.
The only parts you'll have to buy are the battery and the water resistant seal for the back glass.
I'd agree to that. I've been a pixel user for a few years now, the only reason I chose them over Samsung is that I don't like Samsung's software preload.
Samsung certainly isn't making any more but you can still find some reputable 3rd party replacements for batteries. iFixit comes in highly recommend here again. Screens are the only thing I'd recommend getting an OEM part for, and luckily Samsung still makes those.
I have usb-c chargers scattered around the house so that I can charge whatever I have (phone, iPad, Switch) wherever I am. Prefer a single standard, whatever it is.
Wireless power sharing makes it worth it to me. It's not helpful often but being able to charge someones phone in a pinch has saved my ass a few times.
I think the idea of reverse wireless charging is cool as hell, but only if you have wireless buds or a smartwatch to take advantage of it.
The heat, energy loss, and extra time to use wireless charging is not worth it to use full time imo. You also cannot use your device nearly as much on a wireless charger vs a long cable.
But when it's integrated into bar tops, tables, etc., to charge your phone while at a restaurant or something, that's extremely convenient.
Yeah it's niche use doesn't really make it a selling point for me, others things I'd rather have before it.
The reverse charging is a cool feature though, but I feel like phone batteries just aren't big enough for it to be useful outside of a quick partial charge of something like a smartwatch like you mentioned.
Maybe once the tech advances a bit more I can be convinced, but right now a cable does the job well.
