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.
I used to do that because I love new shiny things and at that time most Android phones did not get software upgrades anyway. So I just bought entry-level phones every year. Until in 2016 I found a mid-range phone with the right price at least in my country, and with a good history of software upgrades, the Zenfone 3. I used it until the camera sensor and vibration motor died after about 3 years of use. Today I’m only looking for a phone with atleast 3 years of upgrades and replace it until it fails. I plan to use my current Samsung A54 until it doesn’t receive software upgrades and patches for the next 5 years.
