手机后盖材质加速进化:塑料 “屈居” 入门机,玻纤成了新宠
3 6 Ke· 2025-08-26 07:12
而要说手机后盖材质中的钉子户,雷科技绝对会把这一票投给塑料。 近些年,手机外观形态上的创新已逐渐进入瓶颈期,很难再玩出什么花活。 因此手机厂商们逐渐将目光投向了手机后盖材质,不同材质的后盖不但能带来不同的握持手感,而且也能带来更多大胆的设计。 (图片来源:雷科技摄制) 那么,不同材质的手机,到底有哪些差别?在日常使用中又会对我们造成什么影响?这是雷科技要在本文分享的话题。 塑料后盖:实用性拉满但颜值低 其实手机后盖的材质,一直在美观性、实用性和成本之间不断寻求平衡,例如早期的金属后盖,虽然兼顾了耐用和美观,但却会严重影响到手机信号的接 收,以至于金属后盖仅是昙花一现后便匆匆退场。 (图片来源:雷科技摄制) 从手机诞生至今,塑料凭借极低的生产成本、耐高温耐弯折、耐用及不会遮挡信号等特性,成为最常见的后盖材质之一。 不过塑料的缺点也很明显,质感太过拉胯,很难做出手机厂商们想要的「高级感」,哪怕强如苹果,也曾在塑料后盖上栽了个大跟头——其推出的iPhone 5C在销量上翻车,成为史上销量最低的iPhone之一。 目前我们基本只能在一些定位入门的机型上见到塑料后盖的存在,只能说绝大多数用户还是「颜控」,明明塑料材质有 ...

Core Viewpoint - The article discusses the complexities and challenges of smartphone charging technologies, highlighting the evolution of battery capacities and the emergence of various fast charging protocols that have made charging more complicated than before [1]. Charging Technology Overview - Early smartphones had smaller battery capacities and adhered to a unified USB charging standard, which allowed for relatively straightforward charging processes [1]. - Modern smartphones now often exceed 5000mAh in battery capacity, necessitating faster charging solutions to avoid lengthy charging times [1]. Fast Charging Protocols - **PD (Power Delivery)**: A universal protocol supporting USB Type-C devices, capable of delivering different voltages (5/9/12/15/20V) with a maximum power of 100W (PD3.0) or 240W (PD3.1) [2]. - **VOOC**: Developed by OPPO, this protocol features low voltage and high current options (e.g., 5V/6A, 10V/6.5A, 20V/7.5A), allowing for efficient charging with minimal heat generation [4]. - **SCP (Super Charge Protocol)**: Exclusive to Honor devices, SCP utilizes high voltage and high current, with options like 5V/4.5A and newer versions supporting 10V/4A and 20V/5A [5]. Compatibility Issues - Fast charging protocols are often incompatible with one another, requiring users to ensure that their devices, charging heads, and cables all support the same protocol for optimal charging speeds [5].

Core Viewpoints - The main competitors in the new energy vehicle market over the next five years will still be fuel vehicles, with the core competitive point being the differentiated product matrix supply capability for models priced above 200,000 yuan, which currently has significant room for improvement in supply [2][3] - The market share of vehicles priced above 200,000 yuan is expected to exceed 60% in the next 5-10 years, up from the current 30%. The leading brand in this price segment is likely to exceed a 25% market share, potentially surpassing 30%, indicating annual sales exceeding 3 million units [2][3] - The new energy vehicle market is awaiting its "iPhone 4 moment," where technology and blockbuster products mature, leading to a significant increase in market concentration [2][4] Market Analysis - In 2024, the domestic passenger car sales are projected to be approximately 22.6 million units, with fuel vehicles accounting for about 11.5 million units, representing a market share of around 51%. The sales of models priced above 200,000 yuan are estimated at about 6.6 million units, making up 30% of total sales, with fuel vehicles contributing approximately 4.2 million units [3][6] - The market share of fuel vehicles in the 200,000 yuan price range remains substantial, currently at 64%. Despite significant price reductions in the past year to maintain market share, the trend is set, and the market is awaiting the arrival of the "iPhone 4 moment" [3][4] iPhone 4 Moment - The "iPhone 4 moment" refers to two key turning points: the maturity of 3G technology, which allowed smartphones to surpass traditional computers in user experience, and the decline of traditional phone brands' flagship models, which led to a loss of cash flow for R&D and ultimately market exit. This parallels the potential decline in sales of fuel vehicles priced above 200,000 yuan [4][5] Price Segment Analysis - The market share of vehicles priced above 200,000 yuan has increased from 9% in 2019 to 30% in 2023. It is anticipated that this segment will exceed 60% in the next five years, corresponding to sales of at least 12 million units domestically [6][7] - The brands and products in this price segment are crucial for generating sufficient profits to support R&D, branding, and market promotion, creating a flywheel effect. Additionally, this price segment attracts a broad customer base, enhancing brand momentum [6][7] Brand Market Share - In the segment of vehicles priced above 200,000 yuan, the top six fuel vehicle brands hold a market share of approximately 55%, while the top four new energy brands account for about 26-27% [16][17] - The future market structure is expected to resemble the smartphone industry, where a few brands dominate the high-end market. The leading brand in the new energy vehicle segment could capture around 25% of the market share, with annual sales exceeding 3 million units if the overall passenger car sales reach 20 million [17][29] Sales Performance - The average monthly sales of models priced above 200,000 yuan that exceed 10,000 units are defined as "blockbuster products." Currently, only six major fuel vehicle brands and four new energy brands have this capability, with these models accounting for 65% of the overall sales in this price segment [18][19] - The performance of Li Auto is particularly notable, as achieving a market share of 25-30% in the SUV segment priced above 200,000 yuan would significantly enhance its market position before expanding into the sedan market [29][30]

预售首日销量超过60万台的iPhone4,小定首日超过20万辆Cybertruck;现在,还有Yu7发布后1个小时大定超28.9万台,如果一切顺利,这辆车将毫无疑问 载入全球消费电子产品的历史,多年之后,我们依然能在很多地方看到它的名字。 小米最值得一说的,是在"内卷式"竞争的新能源汽车市场里,走出了一条不靠性价比的路,凭借一款同价位段性价比"较低"的产品,实现如此规模的社会 关注度和销量水平。 在资本市场的通常意义之下,这就是成功,也是一家公司走向伟大的必经之路。说白了,你什么时候见过苹果、特斯拉和索尼他们跟你聊过性价比? 当然,你可以说这20万的大定数字,有不少是Su7未交付订单转过来的;也可以说网络上各种各样的质疑声音,包括安全、智驾、外观抄袭等等;上一段 写的那两款消费电子产品,黑子也非常多、声音也非常大,但丝毫不影响他们成就了现象级的商业成功。没办法,老百姓喜欢才是真的喜欢,黑的声音越 大,买的人越多。 从舆论场的观察看,小米已经悄悄开始步上特斯拉的后尘:网上黑子多,销量没输过。在Yu7发布之前,小米Su7已经和曾经的全球车王Model Y在中国全 部车辆月销榜首的位置上斗得有来有回,今年2月、4月 ...
