About Huawei Mate X7 4G
The Huawei Mate X7 4G is a foldable smartphone that combines a large, high-resolution display with a secondary color AM-OLED screen for added versatility. Its 7.99-inch main display delivers a sharp 2416x2210 resolution, making it well-suited for immersive multimedia and productivity tasks.
Running on HarmonyOS 6, the device is powered by 12GB of RAM, ensuring smooth multitasking. A 5524 mAh battery keeps it running throughout the day, and 50W wired charging ensures quick top-ups when needed. Despite its large screen, the Mate X7 4G maintains a slim profile at just 4.5mm thick, though it weighs in at 235 grams. It supports a single SIM card for connectivity.
This variant stands out with 16GB of RAM, offering enhanced performance compared to the base model's 12GB. It also features a slightly larger 5600 mAh battery, up from 5524 mAh, while maintaining the same 50W wired charging.
Unlike the other Collector Edition variant, this one doubles the storage to 1TB. It retains dual SIM support, unlike the base model, but shares this feature with the other listed variants.
