For me it’s the notification light you used to find on older phones, was particularly good to know if your phone was charged without picking it up
How does one safely repair a lithium-ion battery without just swapping it for a working one?
It’s the difference between sitting down for 20 minutes unscrewing various components to get to the damaged battery you need to replace, vs. popping off the back cover and simply swapping out one dead battery for a charged one anytime you run out of power. The former is replaceable. The latter is swappable.
This. Like ten years ago, when Samsungs had swappable batteries, they were super proud of it. They would advertise it as a feature that Apple doesn’t have.
When I was at a festival, Samsung had an activation where you could tweet at them with your phone model and location and they would send someone with a full battery to trade you for yours. It was an amazing free service that I used so many times, and every time, the jealousy on the faces of all the iPhone people was palpable. Then one year, they quietly removed the swappability from their new phones.
Swappable batteries are such a huge feature that most people don’t even know that they want.
