1. Huawei sticks to a low-key strategy, opting for understated smartphone launches.

Contrary to expectations, the recent Huawei Autumn 2023 Launch Conference took an unexpectedly subdued tone. The much-anticipated Mate 60 Pro, believed to be the star of the show, received only a brief mention, leaving enthusiasts and industry watchers surprised.

This strategic shift can be deciphered by considering Huawei’s established strong brand loyalty among Chinese consumers. Previously hampered by the unavailability of 5G chips due to U.S. trade restrictions, Huawei has managed to overcome these hurdles. The recent successful sales of its new devices in China suggest that a flamboyant presentation of specifications at launch events might not yield substantial benefits. In fact, it could inadvertently be interpreted as a provocation amid the escalating tensions between the U.S. and China.

Therefore, in light of the strained bilateral relations, it is projected that Huawei will continue adopting a discreet approach, with future smartphone releases likely avoiding the spotlight at launch events.

2. Maturation of the smartphone industry poses challenges for brands seeking innovation.

Despite Huawei’s success in developing its own 5G-compatible chips amidst U.S. sanctions, the latest smartphone lack groundbreaking features. Innovations such as satellite communication or advanced camera modules (with periscope lenses and variable apertures) are conspicuously absent. Even in the flagship Mate 60 RS model, the emphasis shifts to the distinctive ceramic material on the back shell.

3. Anticipated rise in China’s domestic production ratio.

Before the U.S. sanctions, Huawei heavily relied on foreign suppliers for smartphone components, including RF, baseband, memory, and sensor chips, complementing its self-developed Kirin chips. However, the restrictive policy have compelled Huawei to shift its dependency to domestic Chinese manufacturers.

In the nearly three-year period from the imposition of U.S. sanctions to the recent release of Huawei’s new 5G smartphone, the industry expected Huawei and its supply chain to suffer severe setbacks. However, the China-made ratio of components in Huawei’s new smartphone currently stands at an impressive 90%, with only the DRAM incorporating SK Hynix products.

With Huawei’s return, it is poised to catalyze growth throughout its supply chain. The ongoing trajectory suggests a continual increase in the domestic production ratio of future devices in China.

Chinese smartphone giants like Xiaomi and Vivo are entering the satellite communication technology arena. A Chinese industry insider claimed that Huawei maintains an exclusive hold on satellite communication solutions for smartphones has stirred controversy, resulting in other smartphone manufacturers having to bide their time before introducing their satellite communication features, Jiwei reported.

An insider at China Telecom affirmed that this technology is not exclusively held by Huawei. However, achieving satellite communication on smartphones indeed poses certain technical challenges, crossing over the substantial R&D efforts to break through the bottlenecks on chip module miniaturization (including RF, Baseband Unit, etc), optimizing the TCP/IP protocol over satellite communication, and end user management.

Huawei Mate 60 Pro has emerged as a pioneer in satellite communication, offering support for satellite calling. Industry insiders have revealed that the satellite communication processor within Huawei Mate 60 Pro was specially crafted for Huawei by a research institute under the China Electronics Technology Group Corporation (CETC). Therefore, Huawei Mate 60 partnered with China Telecom to achieve “satellite calls” services via China’s domestic satellite “Tiantong”, which is currently operated by China Telecom.

Moreover, Qualcomm’s recent announcement about partnering with smartphone brands such as Motorola, OnePlus, Honor, OPPO, Vivo, Xiaomi, and others to develop smartphones with satellite communication feature indicates a broader interest in this technology.

Currently, the consumers tends to extend their device-replacement timelines since the upgrades on smartphone hardware stuck in the bottlenecks such as the performance improvements of processors and camera modules are limited, proven by TrendForce’s estimation that the YoY growth rate of the average DRAM content of smartphones will reach around 6.7% for 2023. This projection is a significant improvement compared with the YoY growth rate of 3.9% for 2022. However, TrendForce also forecasts that the YoY growth rate will stay under 10% in the next several years.

As for smartphone CIS, the shipments is projected to decrease from 4.46 billion units in 2022 to a more subdued 4.318 billion units in 2023. That translates to a YoY contraction of 3.2%.

Consequently, satellite communication is poised to become a key selling point, enticing consumers to upgrade their devices. The industry foresees satellite communication features extending beyond high-end smartphones, and becoming available across a wider range of models, with this shift expected to happen between 2024~2025.
