Realme GT7 Features Innovative Back Material with 600% Thermal Conductivity

Key Takeaways

1. Realme’s GT7 Pro will feature the Dimensity 9400+ processor and a large battery of 7000 mAh or more, set to release in April.
2. A new back material called “graphene fiberglass fusion” boasts 600% thermal conductivity compared to standard glass, enhancing heat management.
3. The GT7 is expected to be thinner, lighter, and more resilient than the GT6, which had a plastic back.
4. The camera setup is likely to remain similar to the GT6, featuring a 50MP main lens, a 50MP telephoto lens, and an 8MP ultrawide lens, with 4K video recording capabilities.
5. The front camera will be a 32MP lens capable of 4K video recording at 30fps, although it does not support slow-motion recording.


Realme introduced the GT7 Pro in November of the previous year, and the base version is set to be released in April. According to a prior teaser, this smartphone will feature the Dimensity 9400+, which is believed to be accompanied by a battery of 7000 mAh or more.

New Back Material

Recently, the company disclosed an intriguing feature: a novel back material that allegedly has 600% the thermal conductivity compared to standard glass. They’re calling it a “graphene fiberglass fusion,” which seems to be a first in the industry.

Importance of Thermal Management

This development is significant because many high-performance devices, particularly those from China, typically use larger VC cooling plates connected to the SoC. However, the heat that the VC plate absorbs must be released into the surrounding environment, meaning that neither the front nor the back is effective at conducting heat. Manufacturers have tried using metal back plates, but they come with their own set of problems. If Realme’s claim about the 600% thermal conductivity holds true, it could enhance the sustained performance of the GT7. Additionally, this new back material is said to be thinner, lighter, and more resistant to drops.

Design and Camera Features

The GT7 is anticipated to be both thinner and lighter than its predecessor, the GT6, which measures 8.4mm thick and weighs 207g. The previous model features a plastic back, so the enhancements in heat dissipation and overall feel will be noticeably better.

In terms of the camera setup, the previous model included three lenses on the rear: a 50MP main lens, a 50MP 47mm telephoto lens, and an 8MP ultrawide lens. This configuration supports video recording at 4K 60fps and 1080p 240fps, which is expected to be the same for the new model—if not improved. There’s also a 32MP front camera for selfies, capable of recording 4K at 30fps, but it lacks slow-motion capability.
