According to the latest preliminary results from the International Data Corporation (IDC), vendors shipped a total of 355.2 million smartphones worldwide in the third quarter of 2015 (3Q15), up 6.8% from the 332.6 million units in 3Q14, marking the second highest quarter of shipments on record. The 3Q15 shipments were slightly below IDC's previous forecast of 363.8 million units, largely due to slightly lower than expected iPhone shipments, as well as Android flagship introductions from several top-tier OEMs with price points outside the consumer sweet spot.

Samsung once again remained the overall leader in the worldwide smartphone market with 84.5 million units shipped, up 6.1% from last year. Samsung remained focused on premium handsets with the launch of two new flagship devices, the Galaxy S6 edge + and Note5. Beating Apple to the punch with an untraditional August launch for the Note series (and new S6 edge +), Samsung saw stronger than normal September shipments as the new iPhone was yet to be released. Outside of the key flagship models, sub-$200 devices (Galaxy Core/Grand Prime, J-Series) drove a majority of shipments in many key emerging markets.

Apple's newest iPhones helped drive third quarter shipments of 48.0 million units, up 22.2% from the 39.3 million units last year. With a record-breaking 13 million iPhone 6S and 6S Plus units shipped during launch week, the two new models continue to capture upgraders and Android converts alike in many key markets such as China and the United States. The arrival of the new "S" models brings a new Rose gold color to the table along with Force Touch, improved camera, and a faster processor. Older iPhone 5S, 6, and 6 Plus models also sold vigorously during the quarter thanks to recent price cuts across all models. Apple's recently launched upgrade plan should also help drive handset upgrades in developed markets where smartphone saturation continues to increase.

Huawei shipped 26.5 million units, up an impressive 60.9% from last year. Huawei once again focused its efforts on the mid-to-high range as nearly a third of the quarterly shipments were in this price range. Devices like the Honor 6 Plus and Ascend P8 helped grow the mid-to-high range 25% from last year according to Huawei. Despite the rapid growth in China and Europe, Huawei will need to focus on the United States where its presence remains relatively low. The recent launch of the new premium Nexus 6P device could signal that Huawei is finally ready to seriously compete in the U.S.

Lenovo continued to fight its way to the top of the smartphone market with help from its acquired assets in Motorola. In the third quarter, combined shipments of Lenovo and Motorola-branded smartphones reached 18.8 million, which was up 11.1% from a year ago. Lenovo-branded smartphones have predominantly been a China play, although recently growth has taken off in Middle East & Africa, as well as Central & Eastern Europe. Motorola's strong markets continue to be North America and Latin America, where its variants of Moto X, G, and E hit on attractive price tiers.

Xiaomi shipped 18.3 million smartphones in 3Q15, bringing its 2015 total to 52.1 million. While the company continues its pursuit of branching off into Southeast Asia, India, and Brazil, China still remains the sweet spot for the company. Within China, Xiaomi launched the Redmi Note 2, Redmi 2A Prime, as well as the Mi 4c in the third quarter. The Redmi Note 2 was the most popular model among Chinese consumers and drove volumes through Xiaomi's retail location known as the Mi Home.
