Other than your carrier give it for free or cheap, I don’t really see the reason why should you buy new phone. I’ve been using Redmi Note 9 for past 3 years and recently got my had on Poco F5. I don’t see the point of my ‘upgrade’. I sold it and come back to my Note 9. Gaming? Most of them are p2w or microtransaction garbage or just gimped version of its PC/Console counterpart. I mean, $400 still get you PS4, TV and Switch if you don’t mind buying used. At least here where I live. Storage? Dude, newer phone wont even let you have SD Card. Features? Well, all I see is newer phones take more features than it adds. Headphone jack, more ads, and repairability are to name a few. Battery? Just replace them. However, my Note 9 still get through day with one 80% charge in the dawn. Which takes 1 hour.
I am genuinely curious why newer phone always selling like hot cakes. Since there’s virtually no difference between 4gb of RAM and 12gb of RAM, or 12mp camera and 100mp camera on phone.
They’ve been a “not user serviceable” component since before phones got water proofing.
Additionally plenty of things can be disassembled with screws and such, that are waterproof… Watches come to mind.
The fact that they’re making it impossible for we the people and owners of the products, to change the battery isn’t a technological limitation, nor a practical one. They did it so people will be forced to seek help to get a new battery, at which time, the vendor/carrier/whomever, can simply upsell the end user.
They did it to sell more phones. If you believe anything other than that, I have some land in Alaska to sell you.
