> Phones don't have removable batteries mostly because of the desire to make the device as thin as possible. The battery is just a delicate, flexible pouch that can easily be damaged and catch fire if removed from the phone and carried around. To make it safe, you'd need to add a hard shell, which would probably make the device 2 mm thicker or so.
Fairphone 6, recent with replaceable battery: 9.6 mm
Galaxy S5, has a replaceable battery, released _12 years ago_ - battery tech has improved a lot since then: 8.1 mm
iPhone 17 Pro Max: 8.8 mm
iPhone 12 Pro Max: 7.4 mm
We want to make phones as thin as possible so the latest flagship iPhone is 1.4 mm thicker than the one from 5 years ago? A whole 0.8 mm thinner than a recent one with a replaceable battery with maybe 0.1% of the iPhone's R&D budget, and 0.8 mm thicker than one with a replaceable battery made 12 years ago?
Galaxy S5 had a tool-free replaceable 2800mAh battery, with hard sides for protection. NFC. Wireless charging (as a user-installed option -- again, no tools, but did add some thickness and weight). USB 3 with OTG. HDMI over MHL. An excellent camera for the time. An OLED screen. A headphone jack. An SD card. A sim card. An IR blaster for changing TV channels at the pub. (I'm probably missing some functions here.)
The bootloader was unlocked in many regions (and became unlockable in all regions). Custom roms were abundant.
And it was waterproof.
(In the subsequent decade+, I have heard it said over and over again that this is an impossible combination of traits. And yet, there was a time when we had all that.)
