As smartphones accelerate their evolution toward AI-native terminals, on-device AI, multi-app concurrency, and large-scale applications continue to develop, raising the bar for phone RAM management capabilities. Improper RAM management can easily cause app lag, background cleaning, page reloads, crashes, and increased power consumption, directly impacting user experience.

To address these issues, the Telecom Terminal Industry Association has issued the group standard T/TAF 358—2026 "Technical specifications for mobile terminal software resource" which sets unified requirements for how mobile applications and operating systems monitor, prompt, release, and manage memory, providing a technical basis for memory optimization for terminal manufacturers, operating system manufacturers, and application developers.

To ensure the true implementation of standard requirements, the CTTL Terminal Labs (CTTL-T) of China Academy of Information and Communications Technology (CAICT)  (referred to as "Laboratory") relies on a national-level pilot testing platform for information and communication products to build a mobile smart terminal memory management and verification platform, providing standard compliance assessment, application adaptation verification, performance optimization comparison, and re-testing services for mobile terminals, operating systems, and application software. Through pilot testing, the laboratory transformed memory optimization strategies from "experience-driven" to "standard-driven," not only improving user experience for users but also providing reusable memory optimization mechanisms to the R&D side, making the development of phones, operating systems, apps, and agents more targeted and efficient. This helped all parties in the industry chain establish scientific memory management methodologies from the R&D and design side, improve product and service maturity, and effectively address technical challenges brought by memory limitations.

Operating system compliance evaluation

According to standard requirements, verify whether the mobile operating system has established standardized mechanisms for memory monitoring, exception notifications, application notifications, and process management, and determine whether the operating system truly meets the standards.

The laboratory will produce objective, reproducible evaluation results, helping terminal and operating system manufacturers identify issues such as missing mechanisms and non-standard execution, providing a basis for system version optimization and product launches. As part of the pilot verification stage, memory management mechanisms are repeatedly validated and iteratively optimized through standardized testing environments, driving operating system vendors to develop mature and stable memory management solutions and shortening the cycle from technology development to product launch.

Application RAM adaptation verification

Verify whether the app correctly responds to RAM management notifications issued by the operating system, promptly release unused resources, and maintain normal business functions after optimization.

This service is suitable for AI applications, gaming, cameras, social networking, office work, and various other applications. It helps developers identify issues such as excessive memory usage, untimely resource release, and long-term unstable operation, and provides targeted optimization suggestions. As an important part of pilot testing services, application adaptation validation provides developers with a testing platform to test memory optimization effectiveness in real terminal environments, ensuring that memory optimization strategies are thoroughly validated before market launch, reducing R&D trial-and-error costs, and accelerating application maturity.

Performance optimization comparison of A/B models within the same model

By comparing performance in application operation, multitasking, background dwelling, stability, and power consumption, it quantitatively demonstrates the actual effects of operating system and app collaboration according to standards, helping enterprises judge whether standard adaptation improves memory usage efficiency and user experience. Comparative testing is the core method for pilot testing. By using scientific experimental methods that control variables, it provides objective and quantitative pilot data support for all parties in the industry chain, making memory optimization results measurable, comparable, and scalable, forming a complete pilot loop from R&D to product validation.

Rectification, retesting, and joint optimization

For issues found during testing, the laboratory can propose optimization suggestions for both operating systems and applications, assist enterprises in joint debugging, and conduct retests after rectification to confirm whether the issues are resolved and performance has improved.

Relying on the automated verification platform, the laboratory can quickly connect equipment, collect test data, judge standard compliance, and generate reports, forming a complete service closed loop of "standard verification—problem identification—rectification and optimization—retest and confirmation." The closed-loop mechanism is a concrete manifestation of the pilot platform's full-chain service capability of "technology R&D, product validation, and industrial implementation." Through repeated iterative validation, it promotes memory management technology from the laboratory to large-scale application, helping industry chain enterprises overcome memory optimization bottlenecks, reduce R&D costs, and shorten time-to-market.

Through these services, enterprises can obtain standard compliance evaluation reports, application adaptation analysis, A/B performance comparison results, problem lists, and optimization suggestions, providing objective testing support for product development, version releases, and performance promotion.

In the future, the CTTL-T of CAICT will continue to improve the memory management testing capabilities of mobile smart terminals, promote the transformation of standard requirements into testable, verifiable, and practical product capabilities, and continue to play the role of a national-level pilot testing platform. Through specialized pilot services, it will connect the entire chain of memory management from technology R&D to product validation to industrial implementation, helping terminal manufacturers, operating system manufacturers, chip companies, and application developers enhance product quality and user experience.

Smart terminal manufacturers, mobile operating system manufacturers, and application developers are welcome to engage in exchanges and cooperation to jointly promote the implementation of memory management standards for mobile smart terminals and their industrial application.
