VERY GOOD

It's so cool and the pictures are great! Best cover ever!

Best case ever

Todo genial

Great case, i love that i can change photos to upload to the case from time to time. Really makes it customizable which is what i love about this case, although the downside that i seem to have is that it affects the airdrop sharing by bumping the top of the case. It doesn't seems to respond well or at all, and when bumping into another iphone with the extrem inno case it seems to always bring up the apple wallet instead.

great case!

Works exactly as expected. Got one for each of my family members and they love it. We can share images and change the image anytime. Very cool.

La funda es genial, la construcción es buena y lo que hace es alucinante, después de llevarla un tiempo he podido comprobar que esa funda no es para mi, Tengo un cargador inalámbrico en la mesita de noche que no carga el móvil con la funda puesta, tengo que quitarla cada noche, decir que el cargador ya tiene unos años e imagino que la potencia no le da para cargar con la funda de por medio, con una powerbank y el inalámbrico del coche ningún problema, carga bien
Después de probar varios diseños para la pantalla hay que tener en cuenta que no reproduce todos los colores, cuando no puede lo cambia por otro y pierdes la que quieres mostrar de la imagen, pero las imágenes en blanco y negro, o con colores claros se ven muy bien. Suelo dejar el móvil bocarriba con lo que también oculto la pantalla que es lo que realmente destaca en la funda, y en mi caso por la forma de coger el móvil se me hacía incómodo tener la protuberancia de la pantalla, que aunque no es muy grande, ahí está
En definitiva, la funda muy bien, pero al final no me he hecho a ella, probablemente la usaré en momentos más puntuales para aprovechar su pantalla, como en hallowen o navidad por ejemplo

Cool fun and functionnal. Good ans verry easy to use.

Aww, thank you so much! We’re happy you love it ! Hope you have lots of fun changing up your XTREM case and making it your own! ✨💛

Great

lol ，l like this.

The best and the coolest case ever !

Great service in recovery! love the customer service attentiveness and service when there is an issue.

Wish it were brighter but still a cool case

Thank you so much! 🥹 We’re glad you think it’s cool! E-Ink technology has a more paper-like appearance and doesn’t emit light on its own, so the display may look less bright than a traditional phone screen. We really appreciate your feedback and support! 🫶

كفر جدا ممتاز وفكرته حلوة

vrey good

Cute idea, magnet is a little weak for me but definitely supports magsafe charging

Thank you so much! ❤️ The magnet should provide a secure connection. If you experience any issues with the magnetic connection, please feel free to reach out to us anytime. We’re always happy to help! 🫶

See All FAQs

How does the XTREM E-Ink display work?

The XTREM case features a circular, four-color E-Ink display on the back. Use the companion app to send an image to the display. E-Ink technology maintains the displayed image without requiring continuous power.

Does the case have a battery or need charging?

No. The E-Ink display does not have a built-in battery and does not require a charging cable. Once an image is displayed, it remains visible without continuous power.

Will the case drain my iPhone battery?

The case does not continuously draw power from your iPhone to maintain the displayed image. Sending an image uses a small amount of your phone's power.

How do I change the image on my case?

Open the companion app, choose the image you want, and follow the in-app instructions to send it to your case's display.

The app is currently called G Shell and is expected to be renamed XTREM INNO in late November 2026. During the transition, you may still see the name G Shell.

How does image transfer work?

For iPhone 14–17 models, image transfer uses NFC. iPhone 18 models support NFC and Bluetooth as an additional image-transfer option. The available method depends on your iPhone model and app version.

When using NFC, keep your phone close to the appropriate area of the case and follow the app's instructions.

Will my image stay on the display when my phone is turned off or the case is removed?

Yes. The E-Ink display maintains the image without continuous power, so the image can remain visible when your phone is turned off or the case is removed.

How many colors does the display support?

The current display supports four colors. Because E-Ink technology differs from conventional phone screens, the appearance of colors and image details may vary depending on the image and lighting conditions.

What images can I display?

You can use personal photos, pictures of pets, memories, logos, and simple graphics. Image appearance depends on the original image and the characteristics of the E-Ink display.

Is the XTREM case compatible with MagSafe?

The case is designed to be compatible with MagSafe accessories, including compatible magnetic wallets, mounts, and wireless chargers. Compatibility and performance may vary depending on the accessory and iPhone model.

Does the case support wireless charging?

The case is designed to be compatible with compatible wireless chargers and MagSafe accessories. Charging performance may vary depending on the iPhone model, charger, and accessory.

What materials is the case made from?

The case combines a PC shell and TPU frame, together with a circular E-Ink display.

How much protection does the case provide?

The case is designed for everyday use and features raised edges around the camera and display to help reduce direct contact with surfaces. We do not claim a specific drop-test rating.

Can I share images with another XTREM case?

Where supported by the companion app and compatible devices, you can link XTREM cases and send images to each other's displays. Follow the in-app instructions to connect the cases.

What should I do if the display does not update?

First, make sure you are using the latest available version of the companion app and firmware. Follow the in-app instructions and keep your phone close to the case when using NFC. You can also restart the app and try again.

If the issue continues, contact us at hi@helloxtrem.com with your order number and a description of the problem.

How do I clean the case?

Use a soft, slightly damp cloth to clean the case. Avoid harsh chemicals, abrasive cleaners, and excessive moisture around the display and openings.

How do I install or remove the case?

Choose the correct case model for your iPhone. Gently fit the phone into the case, making sure the corners are securely in place.

To remove it, gently release one corner and ease the phone out. Avoid excessive bending or applying direct pressure to the E-Ink display.

What should I do if my case arrives damaged or I receive the wrong item?

Please email hi@helloxtrem.com with your order number and clear photos or a short video showing the issue. Our team will review the details and help you with the next steps under our Refund Policy.

Is G Shell being discontinued?

G Shell is expected to be renamed XTREM INNO in late November 2026. This is a companion app name change. During the transition, some users may still see G Shell. Please follow the app instructions provided for your device and current app version.
