It's really funny to me that we're having these conversations all over again. I had the Moto Z back in 2016 and it was almost half a mm thinner than the 2025 iPhone Air. (As always, here's Apple still playing catchup, a decade later this time.)

I honestly didn't mind it - the Moto Z had a Moto Mods battery that snapped on the back (in a MUCH more elegant manner than Apple's magsafe battery implementation in my opinion) and so I always knew that was an option if the battery life became a concern over time. And I loved that the extended battery made the back of the phone perfectly flush with the camera bump too, so if you elected to add battery life, it was literally what we've all asked for the whole time: Just make it thicker and add battery. But if you didn't need extended battery life, then you had a razer thin phone (and a camera bump), probably the thinnest I had until the Fold7 at 4.2mm.

I wish that Motorola's solution had stuck, because they solved this problem already, meanwhile everybody is here reinventing the wheel over and over again in 2025. 🤦
