箱子和设备 - 花很少的钱买很多的内存
realme主要以其中上等的智能手机而闻名，想用很少的钱与其他厂商的旗舰手机竞争。然而，realme也通过其C系列为非常小的预算提供预算手机。今天，我们来看看realme C25Y，它想用快速充电技术和高分辨率的摄像头来说服人们，但价格却大大低于200欧元（约227美元）。
realme C25Y有两种配置。
- realme C25Y配备64GB大容量存储和4GB内存：160欧元（约181美元）
- realme C25Y与128GB大容量存储和4GB内存：170欧元（约合人民币193元）。
我们的测试设备配备了较大的存储配置，以及颜色变体冰川蓝，一种带有颜色渐变的浅蓝色。也有一个名为金属灰的深灰色变体。
外壳由塑料背板制成，质地细腻，巧妙地增强了这种廉价材料的触觉效果。正面甚至允许中等压力到达屏幕，在那里可以看到液晶，但该设备在其他方面制造得很干净。显示屏保护膜是在出厂前就贴好的。
6.5英寸的屏幕和200克（约7盎司）的重量，该智能手机完全符合这个价格范围内的等级标准。
在功能方面，我们不得不批评缺乏NFC。此外，realme手机仍然使用micro-USB接口，这也是即将被淘汰的时候了。
microSD读卡器与两个SIM卡插槽分开安装，因此可以同时使用。在使用我们参考的microSD Angelbird V60进行数据传输时，该智能手机达到了其价格范围的平均速率。

通信、软件和操作--对于价格范围来说是快速的
WiFi 4是realme C25Y支持的最快WLAN标准。至少在我们用参考路由器Netgear Nighthawk AX12进行的测试中，该设备实现了约100MBit/s的体面传输率，而且数据率也保持相对稳定。该 Redmi Note 8 2021显示，有可能会更快，但我们的测试设备在同类比较中表现不俗。
realme UI是基于Android 11，安全补丁是在测试时从2021年9月开始的，因此已经过时了。这款智能手机肯定会被更新到Android 12或realme UI 3.0。
指纹传感器位于智能手机的背面，它也可以直接从待机状态下拾取realme C25Y，但延迟很小。识别精度很好，但就我们的口味而言，指纹识别器相当高，所以手小的人可能很难够到传感器。

照相机--细节上的锐度微弱
主摄像头是背面的5000万像素摄像头，在正常运行时将4个像素合二为一，从而创造出1200万像素的照片，完全可以满足绝大多数应用的需要，并且具有更高的感光性。然而，那些想使用全部像素的人也可以在特殊模式下拍摄5000万像素的照片。
室外的图像质量还不错，但在较大的区域你可以很清楚地看到像素伪影，这使绘图看起来不干净。动态范围还可以，但图像清晰度只能算一般。在低光照和高对比度的情况下，自动对焦功能很难创造出真正清晰的图像。
视频可以用最大的1080p和30帧录制，质量可以接受，但自动对焦有时会不堪重负。
除了主摄像头，还有2个摄像头，每个分辨率为200万像素。一个微距相机和一个支持模糊效果的镜头。
前面是一个800万像素的镜头，可以拍出体面的自拍，但你不应该把它们放大太多。然后图像的清晰度和细节精度会迅速下降。

显示 - realme C25Y的黑屏
realme C25Y采用720p的IPS屏幕。平均亮度不能与这个价格范围内的其他智能手机竞争，只够在阴天的户外使用。
由于黑值相当高，在高屏幕亮度下，黑暗区域看起来相当灰暗，但色彩再现的准确性达到了一流水平。
我们注意到在很低的屏幕亮度下有PWM闪烁，所以敏感的用户在购买智能手机之前应该先试一下，看看他们是否觉得有问题。

性能、排放和电池寿命--功率尚可，热量尚可
该 统一的T610有8个核心，性能高达2GHz。得益于此，该智能手机在其价格范围内实现了非常好的性能率，甚至是 小米Redmi Note 8在这里也无法跟上。你不应该期待高端动力，但realme C25Y不时感觉比其价格范围内的同事更顺畅一些。
另一方面，eMMC存储并不是速度的典范，它的低传输率反而拖慢了系统。
高的处理器功率似乎导致了冷却问题。我们在较长时间的负载后，在机箱上测量到了近50℃（122°F）的温度。这是令人不快的，而且在热天可能会变得更糟。很少在智能手机上玩游戏或运行类似的复杂应用程序的用户应该不会注意到这一点，但其他所有人都应该注意到负载下的热外壳。
扬声器位于智能手机的背面，紧挨着微型USB接口，这是很久以前的手机时代的另一个遗物。一个小隔板至少应能防止扬声器搁置在表面上并被覆盖。然而，当realme C25Y被放在柔软的表面上时，如床单，它并没有什么帮助。在声音方面，高音部分被极度强调，所以听音乐或电影原声带很难有乐趣。外部音频设备可以通过3.5毫米插孔或蓝牙连接。这样做效果很好，大大改善了声音。
在我们的电池测试中，这款手机持续了16个多小时，其中一个剧本通过WLAN上网。这是一个很好的价值，5,000毫安的大电池带来了回报。诺基亚 诺基亚G20持续的时间要长得多。Realme C25Y可以用18瓦特充电，因此通常在不到2小时内就能充满电池，而且很快就有足够的电量使用几个小时，这是非常好的。

Pros
Cons
结论 - realme手机中不及时的细节
在内存方面，realme C25Y在这个价格段几乎没有优势，但你必须没有NFC，不幸的是你也没有得到一个明亮的屏幕。PWM闪烁和高黑值进一步降低了屏幕的亮度，而扬声器的位置不利，声音极度偏重，也让人讨厌。
realme在其手机中安装了一个过时的微型USB接口，这很令人恼火。USB-C早已确立了自己的标准，并最终导致远离了连接和电缆的杂乱。你也不应该期望有太多的安全更新，而且在这个价格范围内，当涉及到相机时，有更清晰的传感器。此外，智能手机在长时间加载后会发热得很厉害。
realme C25Y值得推荐吗？嗯，高计算能力、快速充电和良好的运行时间绝对可以说服人。即使是那些想用小钱买大内存的人也会觉得物有所值。然而，我们上面提到的许多负面因素仍然使我们对整体推荐感到犹豫。
realme C25Y是一款便宜的手机，在同类产品中具有很强的计算能力，但也存在一些问题。
如果你还能应付较少的电池寿命，你可能要考虑 Redmi Note 8 2021它甚至有一个全高清屏幕。与 诺基亚G20你可以得到相当纯粹的Android 和一个广角摄像头，以及更多的耐力，但价格相近。
价格和可用性
realme C25Y有64或128GB的存储空间。在美国，你可以以大约200美元的价格拥有更高端的128GB机型：在亚马逊上购买国际版灰色.
