The Cost Secrets of Smartphone Manufacturers: Why Your Mid-Range Phone Lacks a Metal Frame and Ultrasonic Fingerprint Scanner

The smartphone market is increasingly competitive, forcing manufacturers to meticulously strategize their product lines. A successful new phone launch requires careful consideration of technological advancements, supply chain management, and user demands. However, significant differences in features and user experience exist between different price segments, particularly concerning materials like the phone's frame. Many users question why mid-range phones rarely feature metal frames or ultrasonic fingerprint unlocking. This article will unravel the truth behind these questions by analyzing the hardware costs involved.

First, let's examine the cost difference between metal and plastic frames. Market reports suggest a metal frame costs around $15, while a plastic frame costs only $6. While some users perceive minimal differences in the user experience between metal and plastic frames, this $9 difference is magnified astronomically when considering millions of units shipped. For phones targeting the budget-conscious or offline markets, which often boast massive sales volumes, using a plastic frame effectively controls costs.

Metal frames require complex CNC machining, resulting in higher costs, but offer superior feel, heat dissipation, and durability compared to plastic. Therefore, metal frames are typically found in high-end flagship models. Plastic frames, using injection molding, are inexpensive, lightweight, and common in budget phones. Some manufacturers use "metal-texture coatings" or composite materials (like glass fiber + plastic) to mimic the look of metal, reducing costs while maintaining a mid-range positioning. However, cost remains the ultimate deciding factor in frame material selection.

Ultrasonic fingerprint unlocking faces a similar dilemma. While increasingly prevalent, it's considerably more expensive than traditional optical fingerprint sensors. Data indicates 3D ultrasonic fingerprint sensors cost around $4, while optical sensors cost just $1a fourfold difference. Although manufacturers can reduce costs through bulk purchasing or deep supply chain partnerships, widespread adoption of ultrasonic fingerprint technology in mid-range phones remains unrealistic in the short term.

Beyond the frame and fingerprint scanner, the vibration motor significantly impacts user experience. Linear X-axis motors provide more precise and refined haptic feedback, costing around $1.5. Rotary motors like the 0809 motor, while cheaper (approximately $0.4), offer slower response times and a coarser feel, typically found in entry-level phones. Software algorithms can partially compensate for the 0809 motor's limitations, but these cannot fully overcome its inherent hardware deficiencies.

The refined haptic feedback of linear X-axis motors is particularly valuable in gaming and typing, becoming a key competitive advantage in flagship phones' "hidden features." However, mid-to-low-end users are generally less sensitive to haptic feedback nuances, allowing manufacturers flexibility in their choices based on their target audience.

It's important to note that manufacturing millions of units can significantly reduce per-unit hardware costs. For example, the price of a metal frame could drop from $15 to $12. This requires long-term agreements with suppliers and carries inventory risk. Furthermore, these prices are base prices; different manufacturing processes will affect the final cost. The Bill of Materials (BOM) only includes hardware costs; the final return on investment (ROI) considers many more factors. Pricing also varies between manufacturers, so these figures are for reference only, and such data is rarely publicly disclosed.

In conclusion, smartphone manufacturers consider cost and product positioning when selecting components. High-end models prioritize ultrasonic fingerprint sensors, metal frames, and X-axis motors for enhanced security, premium feel, and user experience. Mid-range phones often use a mix of componentslike thin optical fingerprint sensors, composite frames, and 0809 motorscompensating for hardware limitations with fast charging or superior camera features. Budget-focused phones prioritize extreme cost reduction, using plastic frames and basic fingerprint sensors, relying on distribution channels and economies of scale for profitability.

As domestic (presumably Chinese) supply chain technology advances, mid-range hardware is expected to improve, shifting the industry from pure specification wars towards a greater focus on user experience value.

In short, analyzing smartphone BOM cost data, along with current industry trends and supply chain information, reveals manufacturers' strategic considerations. Hopefully, manufacturers will pay closer attention to detail and enhance the user experience in future phone releases.
