Chinese smartphone manufacturers are reportedly turning to recycled memory chips recovered from discarded phones, computers and servers to control rising production costs. Some of the salvaged DRAM chips have already been used for five to six years and could be deployed in new devices for several more years.
The trend highlights the growing pressure on smartphone makers as the artificial intelligence boom drives demand for memory chips used in data centres. According to industry reports published in October 2026, recycled memory is becoming an increasingly attractive option for manufacturers of budget smartphones in China.
Why Are Smartphone Makers Reusing Old RAM?
Memory prices have surged as semiconductor manufacturers prioritise more profitable products, particularly high-bandwidth memory (HBM) and server DRAM used in AI infrastructure.
This has created supply constraints for low-power DRAM, or LPDDR, which is widely used in smartphones. Budget smartphone manufacturers are especially vulnerable because their profit margins are thin and passing higher component costs on to consumers can make their devices less competitive.
Recycled memory chips reportedly cost around 40% to 60% of the price of new components. This discount gives manufacturers an opportunity to reduce costs and continue producing affordable devices despite rising component prices.
How Are Old Memory Chips Recycled?
The process begins with discarded smartphones and other electronic devices. Technicians remove memory chips soldered onto circuit boards, clean them, remove residual solder and conduct performance tests before preparing them for reuse.
China’s Huaqiangbei electronics market in Shenzhen has reportedly become an important trading hub for recovered memory chips. Some processing and refurbishment activities also take place in manufacturing centres such as Dongguan and Huizhou.
The recovered components are then sold to manufacturers and other businesses looking for lower-cost memory supplies.
Although this approach can extend the useful life of electronic components and reduce waste, the quality of the resulting chips depends on their previous usage, handling and testing.
Could Your New Smartphone Contain Used RAM?
Reports suggest that recycled memory is primarily being considered for ultra-low-cost and entry-level smartphones, rather than premium flagship devices.
Some manufacturers are reportedly exploring the use of recycled chips for a substantial portion, or potentially all, of the memory in certain budget models. However, the identities of the manufacturers involved have not been established conclusively.
There is also no confirmed evidence that leading international brands such as Xiaomi, Oppo, Vivo, Honor and Huawei are routinely installing recycled DRAM in their flagship smartphones.
The distinction matters because reports about a growing recycling market should not be interpreted as proof that every Chinese smartphone brand is using previously owned memory.
Reliability Concerns: Can Old RAM Last Another Six Years?
The biggest concern is reliability. DRAM chips can deteriorate over time, potentially reducing their ability to retain data correctly. Removing a chip from one circuit board and soldering it onto another can introduce additional risks if the process is not carefully controlled.
Ageing memory may experience more data-retention errors, potentially causing applications to crash, devices to freeze or systems to behave unpredictably. The actual risk depends on the chip’s condition, operating environment and quality-control procedures.
A chip that passes a basic performance test may not necessarily offer the same long-term reliability as a new component with a documented manufacturing and usage history.
There is no evidence that recycled RAM has already caused widespread smartphone failures, but the practice raises legitimate questions about durability and quality assurance.
AI Is Changing the Economics of Smartphone Manufacturing
The growing use of recycled DRAM illustrates how demand for AI infrastructure is affecting the broader electronics industry. As manufacturers direct production capacity towards memory used in data centres, smartphone companies face greater competition for components.
This pressure could have consequences beyond China, including higher handset prices, reduced memory configurations and greater interest in alternative component sourcing.
For consumers, the key issue is transparency. Manufacturers should clearly disclose the use of previously used components where applicable and provide reliable information about testing, warranty coverage and expected product lifespan.
Summary
Chinese manufacturers are reportedly recycling DRAM chips that have already been used for five to six years to help produce cheaper smartphones. The practice is gaining attention as AI data-centre demand contributes to a global memory shortage and rising component prices. Recycled chips can cost significantly less than new ones, but ageing components may carry greater reliability risks. For now, the trend appears concentrated in budget devices, and widespread use by major flagship brands has not been confirmed.
