结论 小米红米 15C 4G
小米红米 15C 4G 在摄像头、扬声器、性能和外壳质量方面都没有超出同类产品的标准。在某些情况下，鉴于互联网上的低价，你不应该抱有太多期望。
不过，说到续航时间，在我们的无线局域网测试中，它的续航时间达到了 21 个小时，足以让你在不充电的情况下使用手机数天。此外，它的充电速度相当快，触摸屏精确，更新承诺长达 2031 年。
如果你只用智能手机执行简单、标准的任务，或者正在寻找一款屏幕大、电池续航时间长的第二部手机，那么小米红米 15C 4G 是一个不错的选择。
Pros
Cons
规格
外壳和功能 - 廉价塑料
小米公司用塑料包裹其经济实惠的红米 15C 4G，并提供不同的颜色款式：黑色和薄荷绿（纯色背面），以及蓝色和橙色（波浪形图案，还略带彩虹色）。
在稳定性方面，你不应该有太高的期望：手机很容易扭动，然后会出现明显的吱吱声。
与前代产品相比 红米 14C设计有所改变，尤其是以前圆形的摄像头模块现在移到了侧面，变得更加方正。红米 15C 重 211 克，不算太重。
从正面看，由于屏幕下方的宽下巴和水滴形凹槽，低价位特征明显，但至少屏幕有大猩猩 3 号玻璃保护。
该机配备了用于移动支付的 NFC 功能，可以同时使用两张 SIM 卡，但没有 eSIM 卡。有一个独立的 microSD 卡插槽，读卡器可以快速写入和读取 microSD 卡。

通信和操作 - 可靠的无线局域网
WiFi 5 是最快的 Wi-Fi 标准。红米 15C 的传输速率通常在 220 到 350 MBit/s 之间，只是偶尔会低于 200 MBit/s。即使在距离路由器 10 米远的地方，隔着两堵墙，接收率仍能达到 50%，而且速度也不错。
移动网络可通过 LTE 标准连接，所有必要的频率均可使用。不过，在国外旅行时，您应该提前确认是否支持所需的频率。
触摸屏的响应速度非常快，采样率高达 240 Hz，帧频高达 120 Hz，操作十分可靠。指纹传感器内置在右侧的待机键中，稍候即可解锁智能手机。还可以进行面部解锁。

软件和可持续性 - 更新时间长
HyperOS 2 是手机用户界面的名称，基于Android 15。安全补丁的日期是从 2025 年 8 月开始的，因此在测试时有些过时。不过，小米承诺更新至 2031 年，即从发布算起的 6 年，以及至少两个新的Android 版本。
在设备的可持续发展方面，制造商保持低调。在欧洲，您可以登录Xiaomi了解备件的大致价格，而且包装基本不使用塑料。
相机 - 入门级质量
虽然前代产品的背面仍有四个相机镜头开孔，但这次小米变得更加诚实，只在那里放置了两个实际使用的镜头。
不过，只有主摄像头可以拍摄照片。它的分辨率为 5000 万像素，拍摄的照片整体上比较平庸。不过，考虑到价格区间，弱光下的清晰度还算可以。
视频最高可录制 1080p 和 30 fps。自动对焦通常比较慢，曝光补偿也是如此。不过，考虑到价格，图像清晰度还算可以。
与红米 14C 相比，前置摄像头的像素甚至略有下降：新手机只有 800 万像素传感器。该摄像头拍摄的自拍照还算可以接受，但会出现明显的蓝色偏差，尤其会使面部变形。
显示屏 - 低分辨率，但无 PWM
6.9 英寸屏幕的分辨率为 1,600 x 702 像素，达到了同类产品的水平。不过，由于只有 254 PPI，显示效果显得有些粗糙。
全白时最大亮度为 526 cd/m²，亮度相当不错。这意味着该手机在阴天也能在户外使用。
色彩明显偏绿。我们无法检测到 PWM 闪烁。

性能、排放和电池寿命--几乎可以永久使用
采用 联发科 Helio G81 Ultra采用了最高主频为 2 GHz 的 SoC。它并不总能实现流畅的系统运行，也不适合人工智能计算。不过，总的来说，它与同价位的设备相当，在执行简单任务时速度足够快。
红米 15C 4G 在内存方面没有优势：eMMC 闪存确保了较长的加载时间和相对较慢的数据传输速度。
外壳上的热量积聚问题并不严重。正如 3DMark 压力测试所显示的那样，即使在长时间加载后，处理器仍能保持同样强劲的性能。
手机底部边缘的单声道扬声器音量很大，但高音偏重，因此听起来比较单薄。外置音频设备可通过 3.5 毫米音频插孔或蓝牙连接。蓝牙音频编解码器的种类不多，但最常见的种类都有。
电池容量大幅增至 6,000 mAh。在我们的 WLAN 测试中，它的续航时间可以达到 21 小时。红米 15C 4G 明显优于其他同价位手机。这款手机的充电功率高达 33 瓦，完全充电周期仅需 2 个多小时。
