The Rise of Slim and Light Smartphones in 2024: A Balancing Act of Technological Breakthrough and Market Demand

Since 2024, the mobile phone industry has witnessed a surge in the popularity of slim and light smartphones, with numerous manufacturers vying to release increasingly thinner and lighter models. For example, the OPPO Reno12 boasts a thickness of just 7.25mm and weighs only 179g, while the vivo S19 measures a mere 7.19mm thick and weighs 193g. This trend isn't limited to the mid-range market; high-end brands like Samsung, Apple, and OPPO are also joining the fray, planning to launch flagship products prioritizing slimness and lightness. But given the smartphone industry's long-standing focus on performance, why the shift towards a lighter form factor? It's less a strategic detour and more a result of underlying technological advancements that have created unprecedented opportunities for slim phone development.

In fact, slim design isn't new to the smartphone industry. In the early stages of smartphone development, lightweight designs were the prevailing trend. In 2013, the Huawei Ascend P6 broke the record for the thinnest flagship smartphone at 6.18mm. Gionee and vivo were particularly prominent players in this early competition, with Gionee's ELIFE S5.1 (5.1mm) and vivo's X5Max (4.75mm) setting benchmarks in 2014 that are still remembered today.

However, these early slim smartphones suffered from significant shortcomings: severely limited specifications. The vivo X5Max, for instance, due to its constrained internal space, only featured a 2000mAh battery, resulting in extremely poor battery life. Media tests revealed a 10% battery drain after just 15 minutes of playing the popular game "Asphalt 8," making it unsuitable for heavy daily use.

After 2018, as smartphone functionality expanded, user demands for performance increased. Demanding applications like large-scale games and high-definition video playback required powerful processors and substantial battery life. Slim smartphones, constrained by their internal space, struggled to accommodate large batteries, making battery life their Achilles' heel. Imaging capabilities were also hampered by hardware limitations, resulting in lower-quality photos and videos. Consequently, slim phones gradually lost their market competitiveness, replaced by devices emphasizing overall performance.

The tide, however, has turned. Since 2024, slim smartphones have returned to the forefront. TF Securities analyst Ming-Chi Kuo predicted the iPhone 17 Air will be approximately 5.5mm at its thinnest point, nearing the 5.3mm thickness of the 11-inch iPad Pro. Meanwhile, foreign media reported that Samsung's upcoming Galaxy S25 Slim is expected to be around 6mm thick with a 6.66-inch screen, larger than the standard S25.

This renewed focus on slimness is driven by several factors. Firstly, consumers increasingly desire portability and novelty; slim phones cater to the need for easy, on-the-go usability. Secondly, and more significantly, breakthroughs in underlying technologies, particularly battery technology, have laid the foundation for the resurgence of slim phones.

With the maturation of silicon-carbon battery technology, smartphone battery capacities have increased dramatically. The OnePlus Ace 3 Pro, for example, boasts a 6100mAh "Ice Crystal Battery," which is nearly 20% smaller and 13.4% lighter than a comparable 6000mAh conventional battery. This means larger batteries can be accommodated within the same or even smaller chassis, making slim phone designs feasible. PChome statistics indicate that in 2024, 32% of straight smartphones featured batteries exceeding 6000mAh, with 56% boasting capacities between 5000mAh and 6000mAh. Nearly half also support 100W+ fast charging. These high-capacity batteries dramatically improve the battery life of slim smartphones, enabling them to meet the needs of daily use even with reduced thickness.

Beyond silicon-carbon batteries, other battery technologies are also advancing. For instance, Samsung's single-cell foldable battery patent promises longer battery life in foldable phones while maintaining a slim profile. These advancements allow smartphones to prioritize slimness without compromising battery life, strongly supporting the comeback of slim designs. We are also seeing foldable phones embracing thinness; OPPO Find series product manager Zhou Yibo revealed that the unfolded thickness of the OPPO Find N5 is approximately 4mm, roughly equivalent to two 1 Yuan coins.

The renewed prominence of slim smartphones in 2024 is not coincidental; it's largely due to rapid advancements in underlying smartphone technologies, allowing manufacturers to prioritize slimness without sacrificing user experience.

However, extreme thinness isn't a panacea; finding the right balance is crucial. Manufacturers cannot prioritize extreme thinness at the expense of performance, camera capabilities, or other aspects of user experience. Excessively slim phones may struggle to accommodate high-performance processors and large heat dissipation modules, impacting speed, stability, and heat management. In terms of photography, the pursuit of thinness might necessitate smaller camera modules and sensors, or reduced optical zoom, resulting in lower image and video quality. For example, the upcoming iPhone 17 Air, rumored to prioritize extreme thinness, may compromise on camera capabilities, featuring only a 48MP main lens and a 24MP front-facing camera, lacking the ultra-wide and telephoto lenses of the Pro models. This might deter photography enthusiasts. Market research suggests that storage, performance, price, and battery life are consumers' top priorities, with thinness rarely ranking highly. This highlights the importance of comprehensive performance, requiring manufacturers to balance slimness with improvements in performance, photography, and battery life.

Fortunately, ongoing advancements in upstream smartphone technologies offer significant potential for improvement in slim phone design. For example, solid-state batteries, currently under development, offer higher energy density, faster charging times, and improved safety, and are poised to become the dominant battery technology for slim phones in the future, creating more space for other components. Furthermore, advancements in artificial intelligence and imaging technologies will enhance photographic capabilities and user experience. Manufacturers can optimize camera algorithms, add AI scene recognition and night modes, etc., to ensure high-quality photos and videos even on slim phones. Honor's "King of Imaging" is a testament to this, with its AI light engine significantly enhancing image quality across various scenarios.

In conclusion, slim smartphones have had a rollercoaster journey in the smartphone industry. From market dominance to temporary obsolescence due to specification limitations, and finally back to center stage with the help of technological breakthroughs, their evolution reflects both industry innovation and evolving consumer demand. A decade ago, thinness was a significant aspiration, but limitations restricted its impact. Recent breakthroughs in battery technology have revitalized the trend. Mature technologies like silicon-carbon batteries significantly increase battery capacity without increasing size. Other related technologies, such as more efficient heat dissipation materials and techniques, and thinner, higher-performance screens, address prior shortcomings. Slim phones are no longer synonymous with weak specifications; they can offer comparable or even superior performance to traditional phones while maintaining portability, thus driving the current trend.

However, the pursuit of thinness must remain balanced. Extreme thinness is not the ultimate goal. While consumers clearly prefer slim phones, they also value performance, camera quality, and battery life. Manufacturers must strike a balance, satisfying the desire for portability without neglecting the overall user experience. This demands significant innovation in R&D and product design, optimizing internal structures and utilizing advanced materials and technologies to achieve a harmonious union of thinness and performance.

Looking forward, the future of slim smartphones is promising. Continued advancements in battery technology, materials science, and other related fields will provide stronger technological support. Consumer demand for slim, high-performance phones will drive further innovation. By meeting the need for portability while continually optimizing specifications and enhancing overall performance, slim smartphones will play an increasingly important role in the smartphone market. They will not only serve as efficient daily tools for consumers but also guide the industry towards a future of slimmer, more efficient, and intelligent devices, creating a more convenient and enjoyable mobile experience.
