NO. iphone15 E-Ink NFC Case Gray 15

What the case is and who it fits

This E-Ink case replaces the back cover on iPhone 13, 14 and 15 models in Gray. It adds a four-colour electronic ink display that draws power only when the image changes, so no battery or charging is required. The case connects through NFC link technology instead of Bluetooth, keeping setup simple. It suits owners who want a personalised, always-visible image without extra bulk or daily charging.

Behaviour under sustained use

The electronic ink screen holds its picture indefinitely without consuming energy, so the display remains visible even after days of inactivity. Because the case has no internal battery, there is no capacity to degrade and no recharge cycle to manage. NFC transfers are brief and only occur when you update the image, so the phone’s own battery is not drained by a constant wireless link. The liquid silicone shell and microfibre lining protect the handset during extended daily handling.

Installation and common pitfalls

Snap the case onto a compatible iPhone 13, 14 or 15, then download the exclusive Smart Cover app to choose or create an image. Hold the phone near the case to push the picture over NFC; the transfer takes seconds and needs no pairing. Pitfalls include trying to use the case on unsupported models, expecting Bluetooth pairing, or assuming the screen refreshes like an LCD — it only updates when you send a new image.
