I have some real world experience
I had an iPhone 5s, which is a beloved and popular model for its compact form factor and ergonomics. Loved that phone. I had it for 6 years.
hates that. There's a secret algorithm they put into your phone to literally slow it down after a few years
and make it use more and more resources, even though the processor and memory are as good as they ever were. So between me playing Pokemon Go and also the secret algorithm, my phone would get pretty hot, and I would have to stop playing pokemon go and let my phone cool off. Fully aware that this is an artificial, BS situation caused by Apple
wanting me to upgrade a perfectly good phone.
But see, it doesn't matter. Heat is the enemy of electronics. Like waves lapping away at the sandcastles of your device. The heat causes the lithium polymers to expand, ever so gently, so they swell. Then they heat up again and that swell swells. Then that swelled swelled swell swells. And so on. Thousands of times. Like a shoehorn jackknifing inside of your tablet, pressing against the walls.
Until your screen pops off. I mean, everything still works, right? The screen works. The buttons work. Just looks a little ugly, right?
So I put purple duct tape across my phone to keep the screen in place and happily kept using it.
In Costa Rica my ex-girlfriend and I were hanging over a balcony basking in the light of the golden sunset over the jungle. Monkeys were leaping from tree to tree in the valley below us. It was an amazing moment. One of those times you just have to take a selfie to remember it.
I reached for my phone, turned to take the selfie, and the phone moved in my hands like it was alive. The duct tape gave way, the screen flung itself back, and the battery inside visibly expanded with a fizzing noise. The control thumb button popped out and tumbled away into the rain forest, lit with flecks of golden sunlight as it fell into the embrace of the jungle.
Later when I went to claim a replacement, the tech support guy simply would not accept that I'd been using a 5s for six years. He kept saying "That model has been discontinued." And I kept saying I never dropped it, not once, never spilled on it, never cracked the screen. Just used it day after day for years and I'd like another one please. He asked me to send him a picture of it. I did. He said, where is the thumb button? I said, in a monkey's nest somewhere in the rain forest of Costa Rica because your BS algorithm that heats up older phones.
I didn't win that one. So I got an Android.
