外壳和设备 - 过时的USB接口
小米的红米12C是一款廉价的智能手机,根据存储配置的不同,购买价格远低于200欧元(约200美元)。
小米提供四种颜色选择:深灰色、紫色、薄荷绿和蓝色。背部由塑料制成,有 一个可触摸的条纹图案,就像前代产品一样 红米10C.相机模块仍然非常笨重,但它现在在颜色方面已经部分适应了背面,看起来更加谨慎。
外壳的稳定性还可以,但在扭动时可以听到安静的吱吱声。屏幕的边缘也有点尖锐。
在小米的网站上可以找到三种不同的存储配置:
- 3GB内存/32GB大容量存储:150欧元
- 3GB内存/64GB大容量存储:170欧元(约570美元)
- 4GB内存/128GB大容量存储:200欧元
然而,由于促销优惠券,你可以得到更便宜的智能手机,红米12C在互联网的其他地方也有很大的折扣出售。
我们不明白小米怎么能在2023年在红米12C上安装microUSB接口。我们以为混乱的各种端口的时代终于结束了,尤其是即使是 红米10C已经有了一个USB-C端口。
除了2个nano-SIM卡,还可以使用microSD读卡器,尽管在我们的参考卡Angelbird V60的测试中,它不是最快的。

通信、软件和操作 - 软件的更新承诺
红米12C的WiFi 5模块比前代产品做得稍好,但在接收速度方面,它不能完全跟上该价格范围内的其他设备。这主要是由于传输速度的短暂下降,即使重复测试,我们也能在不同点上反复观察到这一点。
小米手机可以使用4G作为最快的移动网络,并配备了中欧地区的必要频率。对于进一步的旅行,你应该提前检查你在所在国需要哪些LTE频段,以及红米12C是否支持。移动网络中的接收质量还不错,但无法跟上高端手机。
该软件被称为MiUI 13,但它仍然是基于Android 12。因此,小米为这款手机做出的2个Android 版本的良好更新承诺只延伸到Android 14。至少安全补丁是定期更新的:每3个月一次;在我们的设备上,安全补丁是从2023年3月开始的,在测试的时候是相当最新的。
指纹传感器被集成到背面的相机模块中。在短暂的等待后,它能相当可靠地解锁智能手机。人脸识别也是可能的,但它是基于软件的,因此不那么安全。

照相机--价格范围内的标准传感器
与其他众多廉价手机一样,红米12C使用三星的Isocell JN1作为主摄像头的图像传感器。现在的附加摄像头只有10万像素的镜头,但无论如何不能用来制作照片,只能为人像模式提供额外的数据。
主摄像头拍摄的照片部分是模糊的,亮度也有很大的不足。这不仅在白天注意到,而且在黑暗的照明条件和强烈的对比中也注意到。明亮的区域被过度提亮,而黑暗的区域在照片中几乎看不到任何图案。在实验室的全影棚照明下,该相机也有点模糊,但这里的对比度是可以接受的。
自拍相机位于屏幕顶部的水滴状凹槽中。它的分辨率为500万像素。拍出的照片第一眼看上去相当明亮,但它们没有显示出任何画质,特别是在黑暗区域,放大后的细节相当差。
总的来说,红米12C的摄像头与竞争对手持平。

小米本来有机会在屏幕上脱颖而出:在这个价格范围内,全高清屏幕是绝对有可能的,如 Galaxy A13 4G或 Poco M5,或者非常明亮的屏幕,比如在 摩托G13.
然而,制造商没有这样做,而是安装了一个720p的屏幕,其亮度在我们的测试中甚至低于400cd/m²的平均值。因此,在户外或明亮的房间里,往往很难看到屏幕上的任何东西。
我们没有注意到PWM,但在灰阶中有明显的颜色投射到紫色。总的来说,这块屏幕的色彩准确性还可以。

性能、排放和电池寿命 - 性能良好,耐力好
有了 联发科的Helio G85联发科的Helio G85,以前的中端SoC现在也出现在较低价格地区的手机上了。因此,红米12C实际上被证明比红米10C强得多。 红米10C.与其他廉价手机直接相比,小米手机也提供了大量的动力。
在日常使用中,它在大多数应用程序中运行得相当流畅。只有当你想同时运行几个程序或安装非常复杂的应用程序时,你才会遇到性能问题。然而,你不得不忍受缓慢的eMMC闪存,这使得加载时间和数据传输时间有点长。
在重载的情况下,手机在室温下发热到44.7℃。这意味着在炎热的日子里温度可能会增加得更多,变得令人不快。然而,强烈的热量发展并不影响性能:手机在3DMark压力测试中几乎没有显示任何损失。
下部边缘的小扬声器做得很好:即使在最大音量下也不会失真,能很好地再现声音,只是听起来有点闷。当然,你不应该期望有高保真的声音。需要通过3.5毫米插孔或蓝牙连接外部扬声器或耳机,以获得更好的质量。该手机支持许多蓝牙编解码器,包括最新的编解码器,如aptX TWS+或LHDC v3/v4。
5,000毫安时的电池仍然存在,但小米已将充电功率缩短到10瓦,而在 红米10C,18瓦仍然是可能的。运行时间略有改善,现在在我们的Wi-Fi测试中为15:33小时。这款智能手机无法跟上Moto G13 ,但它的运行时间在其价格范围内仍然非常好。

评语--小米退步了
小米用红米12C更新了它的经济型手机,但削减了一些角落:红米12C的存储速度较慢,充电时间较长,还有一个microUSB端口(!),红米12C落后于它的前辈,但也落后于同价位的其他智能手机。
小米为什么做出这个决定是个好问题。也许是基于这样一个事实,即购买这个价格区间的智能手机的客户对技术细节不是很感兴趣,几乎不把设备与其他手机进行比较。然而,这是一个耻辱,因为红米10C 是朝着正确的方向迈出的一步,而红米12C看起来是一个明显的退步。
除此以外,屏幕可以更亮,高负荷下的强烈发热也是可以预期的。然而,对于这个价格范围内的设备来说,性能率是合适的,在我们的Wi-Fi测试中,超过15小时的电池运行时间也是令人信服的。这款智能手机还按要求提供了大量的存储空间。
红米12C以相对较低的价格提供了体面的性能率,良好的运行时间和NFC,但也有强大的替代品。
前辈红米10C ,现在可以用很少的钱买到128GB的慷慨存储,例如,在notebooksbilliger.de ,只需不到150欧元。我们也喜欢摩托罗拉Moto G13 ,尽管更新供应不清楚。
价格和可用性
在测试时,红米12C的价格在150至200欧元之间,,直接由制造商提供。取决于内存的配置。这里也不时会有折扣。
然而,红米12C在其他在线零售商的价格要低得多:例如,32GB版本在amazon.de只需不到125欧元。64GB版本的价格只比amazon.de多5欧元。.
128GB版本在以下网站已经有售,价格为137欧元 amazon.de,而我们的贷款人cyberport.de收费略低于160欧元。
