Huawei just detailed the launch of its first 5G phone - the Mate 20 X (5G) in China. It will come with 8GB RAM and 256GB storage and cost CNY6,199 ($900/€810). It's currently up for pre-orders on VMall, with sales commencing from August 16.
The Mate 20 X (5G) isn't much different from the Mate 20 X announced last year.

I own a Huawei 20 X/Global. The battery is in fact 5000mAh. However the upcoming Huawei 20 X/5G model's battery is said to be 4200mAh.
Battery capacity is 4200 mAh, not 5000 mAh.
