Smart E-Ink Case for iPhone 13/14/15

This white protective cover integrates a four-colour electronic ink display that refreshes without batteries or Bluetooth pairing. It draws power directly from the phone’s NFC field to update the screen image. The case fits the iPhone 13, 14 and 15 models and adds a customisable visual layer to the rear of the device. Liquid silicone construction with a microfibre liner protects the handset from scratches.

Sustained Use Without Recharging

Because the display is updated only when a new image is sent via NFC, the case consumes no power between changes and never requires a separate charger. The e-ink panel retains the last picture indefinitely, even if the phone battery dies or the case is removed. Users can swap designs as often as they wish through the companion app without worrying about runtime or standby drain. The absence of a battery also means the cover stays slim over the full ownership period.

Passive Thermals and Silent Operation

With no active electronics, the case generates no heat and produces no audible noise during normal use. Power draw is limited to the tiny NFC harvest needed for a screen refresh, which lasts a fraction of a second. The liquid silicone shell dissipates any residual warmth from the phone itself without trapping it. The result is a completely silent, maintenance-free accessory that does not affect the handset’s thermal behaviour.
