Huawei saw year-on-year smartphone shipments spike 63 per cent in its third quarter. Third-quarter deliveries climbed 81 percent and 98 percent in China and Europe respectively from a year ago. About a third of the quarterly shipments were mid- to high-end models, Huawei said, up from 25 percent a year earlier.

By comparison, Huawei rival Xiaomi shipped only 18.5 million smartphones over the same quarter -- 8.9 million fewer than Huawei. Xiaomi had targeted shipping 80 million smartphones worldwide for 2015, but has shipped only 53.2 million handsets for the year as of September.

Huawei's global market share had reached 9.5 percent as of the end of the quarter, placing it in the top three smartphone makers worldwide during January to August.

Since their respective launches, total shipments for the Huawei Mate 7 have reached 6.5 million units; the Huawei Honor 7 has shipped 7.5 million units; and 4 million Huawei P8 and Huawei P8 Max smartphones have shipped. The high-end flagship Huawei Mate S, launched in September, is now available in 48 countries worldwide, including China, Germany, France, the United Kingdom, and Spain.

The Huawei-built 5.7-inch Google Huawei Nexus 6P will also likely achieve a higher penetration rate for the company, with the smartphone available for pre-order now and set to hit store shelves in early November.

Nevertheless, Huawei remains a distant third behind Apple and Samsung, largely because its market penetration remains low in the U.S., where its devices were once labeled a security risk in a U.S. Congressional report. Huawei smartphone market share was worth $7 billion in the second quarter, according to Canalys.
