“Whether it's the smaller battery, the demands of the Tensor chip or some other factor, the Pixel 6a fell flat on our battery test, in which phones surf the web continuously until they run of power. The Pixel 6a lasted an average of 6 hours and 29 minutes, which is more than 3 hours behind the Pixel 5a's result on that same test. Even worse, the Pixel 6a trailed the iPhone SE (2022), and we consider the 9 hour, 5 minute time that Apple's phone produced to be below average for a smartphone.” https://www.tomsguide.com/reviews/google-pixel-6a
That’s the trend, a new model Android phone has near iPhone prices for a device that’s comparable but will have a shorter lifespan/ worse resale price. Buy an older model and you save money today, but need to replace the phone even more frequently.
Further, in each case I did so after three to four years of use. The one exception is an iPhone 8 I a) bought used from Sprint/T-Mobile, and b) traded in after 18 months to the same carrier for an incredible deal toward a new iPhone 13; otherwise I would still be happily using it.[1]
There is no way that any used Android phone, even the most expensive flagship model, would ever be worth anywhere as much. And that's not including their lack of software updates. Meanwhile, the iPhone 5S I sold in 2017 after four years of use believing that it would soon lose software updates a) did not lose active support until 2019, and b) still is getting security fixes (the most recent four months ago)!
[1] More happily than the iPhone 13, really. I hate Hate HATE Face ID.
