Huawei, the consumer electronics company from China, saw its annual sales rise as much as 83% in the first four weeks of October, according to the data from research firm Counterpoint.

Overall, China experienced an 11% rise in total smartphone shipments, fueled by strong sales growth at Huawei. Xiaomi (OTC:XIACF) also saw a notable increase in smartphone sales, with a 33% rise.

Huawei’s turnaround is attributed to the success of its Mate 60 smartphone series, launched in August and powered by a self-developed high-end chip. Mate 60 Pro is seen as a direct rival of Apple’s (AAPL) iPhone 15 Max Pro.

While Counterpoint acknowledged Huawei’s stellar performance, it notes the possibility of lingering bottlenecks and production issues for the company.
