Chinese smartphone makers have been using silicon-carbon battery technology to squeeze enormous capacities into slim devices without sacrificing design. HONOR, one of the brands pushing hardest in this area, is now preparing a model that takes things to another level entirely.

The company's performance-oriented new flagship series, the Honor Win 2, has appeared on the brand's official online store ahead of a launch event in China on October 21. Those listings have clarified the series' key specifications.

The store showed design renders and configuration options for the Win 2, Win RT 2 and Win Turbo 2 models. It also confirmed that the series will ship with a built-in cooling fan — a hardware solution aimed at keeping temperatures in check for gaming and high-performance users.

According to reliable leak source Digital Chat Station, the Win RT 2 will carry the largest battery ever seen in a mainstream smartphone brand: 12,070 mAh. Fast charging support is expected to come in at 90W.

Display and hardware

Up front, the Win RT 2 is set to feature an ultra-slim-bezel 6.89-inch 2K AMOLED panel supporting a 185Hz refresh rate. Powering the device will be the Snapdragon 8 Elite Gen 5 chipset.

Memory and storage options include 12/16 GB of RAM alongside 256/512 GB of storage. With the official launch set for October 21, pricing and availability details are expected to be finalized on that date.
