My Open is about 3 years old now and the battery's getting noticeably worse. The phone itself is still perfect so I don't want to replace it yet, it wasn't perfect even with fresh battery.

I'm thinking of sticking a MagSafe-style ring on the back and attaching a small magnetic power bank, then running a short USB-C cable to the port. Since the Open has no wireless charging it'd have to be wired.

Problem is the space. I measured about 85mm from the bottom of the camera bump to the bottom of the phone, and pretty much every slim 5000mAh bank is 100mm+ tall. The only one I've found that would actually fit is the InfinaCore M3 Mini (83mm), and it's out of stock on Amazon UK.
