Woofun AI reports that Lei Jun explicitly advised consumers at the Xiaomi 17 MAX launch event in late May to upgrade their devices immediately, citing an impending surge in memory chip costs that will inevitably inflate smartphone pricing. This warning stems from a structural shift where major manufacturers including Samsung, SK Hynix, and Micron have diverted advanced production capacity toward high-bandwidth memory (HBM) to satisfy AI demand, drastically reducing the supply of consumer-grade chips for phones and PCs. The severity of this supply constraint is evidenced by Apple's recent admission from CEO Tim Cook to The Wall Street Journal that price increases are "inevitable" and that current cost structures are "unsustainable," despite the company's efforts to control expenses during the 618 shopping festival. IDC forecasts indicate that by 2026, flagship smartphone prices in the Chinese market will rise by more than 30%, with models of identical specifications costing 300 to 1,000 yuan higher than in 2025, while the price gap for larger storage configurations could reach 2,000 yuan. Such aggressive pricing trends historically suppress demand, a dynamic confirmed by IDC data projecting that the average replacement cycle for Chinese consumers will extend to 42 months in 2026, marking an all-time high.

In response to these market pressures, domestic smartphone manufacturers are deploying strategic retention measures rather than remaining passive. Companies like Xiaomi and vivo have initiated testing for 'battery upgrade services,' allowing users to replace aging power cells with newer silicon-carbon anode batteries. The Xiaomi 13 series already permits this specific upgrade, while vivo is actively researching similar high-density battery replacements for older models. This strategy serves a dual purpose: it extends the functional lifespan of existing devices to stabilize market positions during a difficult economic period and enhances customer loyalty among the undecided Android user base. The urgency of retaining these users is heightened by the growing market appeal of iOS and HarmonyOS, which are actively fragmenting the Android ecosystem. For Android manufacturers, hardware sales represent merely the entry point into a broader business model where software services generate the primary long-term value. Historically, domestic brands adopted an internet-based back-end charging model, monetizing user value through advertising and channel fees rather than hardware margins, a strategy that allowed consumers to access superior hardware at lower initial costs in exchange for ubiquitous advertisements.

The viability of this back-end charging model relies heavily on the duration of the user relationship, creating a complex dynamic where longer device lifespans present both risks and opportunities. While extended replacement cycles reduce immediate hardware sales revenue, they simultaneously increase the potential revenue generated from software services over the device's life.

Woofun AI data shows that Xiaomi, the only listed domestic smartphone manufacturer, reported internet service revenue of 37.4 billion yuan for 2025, representing a year-on-year increase of 9.7% with a gross profit margin stabilizing at 76.5%. Within this figure, the 190 million monthly active users in mainland China contributed 24.8 billion yuan in revenue, averaging 130.5 yuan per user annually. This financial structure underscores why retaining old customers is critical; however, the market has shown resistance to alternative models, as seen with the Meizu 18 series. When Meizu attempted to pivot by marketing the device as a "three-zero phone" with no ads, no push notifications, and no pre-installed apps, the market performance was disappointing, proving that consumers were unwilling to pay a premium for ad-free experiences. Consequently, manufacturers continue to spread hardware profits over the entire usage period to lower the perceived cost for consumers, accepting that a longer replacement cycle is a necessary trade-off for sustained software monetization.

The technical rationale for focusing on battery replacement lies in the specific limitations of aging devices versus their remaining processing capabilities. In the past, Android phones rarely lasted beyond three years, but today, hardware iteration speeds far exceed actual user demand, and system optimizations have resolved many historical performance bottlenecks. Modern mid-to-high-end Android devices now standardly feature 12GB or more of memory, paired with powerful flagship chips and manufacturer commitments to four years or more of system maintenance, theoretically enabling a lifespan of over five years. Despite this theoretical longevity, the physical degradation of the battery remains the primary failure point; after three or four years of use, a device may still run smoothly but often suffers from battery life lasting only half a day. Replacing the battery with a silicon-carbon anode offers an immediate solution, as these new cells significantly increase energy density, allowing for greater power storage within the same volume or weight compared to traditional graphite anodes.

Furthermore, silicon-carbon anodes enhance thermal stability and structural integrity, reducing safety risks under extreme conditions such as high temperatures, overcharging, and over-discharging. This upgrade effectively restores daily usability to older devices, providing a cost-effective method to enhance brand reputation without requiring a full hardware replacement.

Beyond customer retention, the introduction of official battery upgrade services by manufacturers like Xiaomi and vivo addresses critical safety concerns arising from the unauthorized modification market. Since the large-scale commercialization of silicon-carbon anode batteries in 2024, the business of retrofitting old phones with these new cells has flourished on e-commerce platforms, with third-party repair shops modifying wiring to accommodate the new technology.

However, these unauthorized modifications carry significant risks, including electrical short circuits, battery overheating, and structural failures. If such incidents occur, users are unlikely to accept responsibility, and the liability would inevitably fall upon the smartphone manufacturers, potentially damaging their brand reputation. By offering official upgrade services, manufacturers can mitigate these safety risks while simultaneously securing the loyalty of their existing user base. This approach transforms a potential liability into a strategic asset, ensuring that the transition to longer device lifespans does not compromise safety or brand integrity. The convergence of rising memory costs, extended replacement cycles, and the strategic deployment of silicon-carbon battery technology marks a definitive shift in how smartphone manufacturers navigate the current economic landscape.
