Doesn't have to cover the entire back of the camera. Just needs to use magsafe to attach.

I don't think magsafe is strong enough to support the entire phone on a keyboard

I use the MagSafe Apple wallet and often turn is sideways to give myself something to hold while I watch videos in landscape. A keyboard would work in much the same way, in terms of what it needs to support and where it’s being held.

MagSafe supports my 'entire phone' bouncing around in my truck, and hanging on my headboard at night - it's more than strong enough to hold a phone to a keyboard.

I enjoy that your unwritten implication is that your headboard is banging around at night with equal amplitude to your truck.

humblebragging at its finest me thinks

Maybe his truck has a really nice, comfy suspension that doesn’t move much. Maybe he’s humblebragging about his truck :P

Fair and good point!

Is this something that has changed with the newer phones? I have an iPhone 12 pro, and MagSafe barely holds the wireless charging circle to the back of the phone.

Supporting the entire phone is the entire point of Magsafe, what else would you even use it for?

It works great to support the entire weight of the phone on your desk or a dashboard, even when driving a fast car or riding a bike (unless you crash of course). But it's 1-2 orders of magnitude less force than required to resist pulling it out of your pocket.

lightly holding the charger in place well enough to maintain contact yet easily removed if the cable is pulled without damaging cable or device. anything after that is bonus and outside the scope of magsafe's use. the magnets on my desktop multi-device charger do not meet that requirement as they are significantly stronger than Magsafe connections.

That wouldn't be very comfortable at all
