机箱和功能 - 坚固的塑料机箱

小米红米A2采用了简单的塑料外壳,背面仿皮革质感。由于采用了磨砂表面,您不必担心指纹或油渍。这款手机有浅蓝、浅绿和黑色可供选择。得益于圆润的边缘设计,红米A2手感舒适,平均重量为192克。

手机结构坚固,不易扭曲。对机身施加压力时也听不到吱吱声。

红米A2目前仅提供32GB存储空间和不到2GB的内存。小米的官方售价为110欧元,但在其网站上的售价甚至低于100欧元。我们发现红米A2配备的是microUSB接口,而不是广泛使用的USB-C接口,这让人很不爽。遗憾的是,红米A2没有NFC功能,但microSD读卡器是独立的,因此它可以与两张插入的SIM卡同时使用。

在我们使用参考microSD卡Angelbird V60进行的测试中,读卡器的速度不算太快,但也不比同价位的其他手机慢。

通信、软件和操作 - 机载WiFi 4

对于不到100欧元(约合100美元)的价格来说,你必须接受红米A2仅提供Wi-Fi 4的事实,这明显反映在其传输速率仅为50 Mbps左右。因此,Wi-Fi模块的速度足以满足上网浏览的需要,但要进行较大的下载则需要等待较长时间。

小米红米A2是一款4G手机,只拥有最必要的频率,因此您必须在进一步出国旅行时检查是否可以连接到LTE网络。在测试过程中,我们反复对接收质量进行随机抽样:在城市环境中通常可以连接到4G网络,但比高端手机要不稳定得多,测试中还出现了两次短暂掉线。

至少小米手机预装了最新的Android 13 Go。制造商还内置了一些广告应用程序,这在内存紧张的情况下尤其令人担忧。作为回报,小米承诺在两年内定期提供安全更新,这对一款如此廉价的手机来说是一个很好的承诺。在测试时,补丁是从2023年5月开始的,因此仍然是相当最新的。

令人讨厌:由于手机未通过Widevine-L1认证,因此只能以标清格式观看主要流媒体平台的视频。

恼人之处 Helio G36作为红米A2的SoC,Helio G36实际上也可以使用90 Hz的屏幕,但小米只安装了最大帧率为60 Hz的显示屏。再加上SoC的性能相当低,内存相当逊色,即使在正常的系统导航中,你也必须做好卡顿和等待时间的准备。没有用于解锁手机的指纹传感器,也没有人脸识别功能。

相机 - 缺乏细节,对比度低

前置摄像头拍摄的照片
前置摄像头拍摄的照片

后置主摄像头的分辨率仅为800万像素,第二个镜头仅用于模糊效果。不过,在光线良好的情况下,仍然可以拍摄出不错的照片。放大后的照片细节丢失明显,对比度也有所欠缺。视频最多可录制30帧/秒的1080p格式,看起来也有点缺乏细节。自动对焦尤其难以提供清晰的图像。

在亮度很低的情况下,光源过度辐射,而在黑暗区域几乎没有任何画质。在摄影棚照明下,相机再现的色彩有些过暗,但总体效果尚可。

前置500万像素自拍摄像头,在光线充足的情况下可拍摄出相当不错的照片。不过,您不应该将其放大太多,也不应该指望它能详细再现黑暗区域。

显示屏 - 色彩再现相当出色

子像素结构
子像素结构

6.52英寸的IPS屏幕分辨率为720p,这在同价位产品中是比较合适的。在亮度方面,红米A2表现中规中矩,平均亮度达到379 cd/m²。较低的黑色值也确保了可接受的对比度。

幸运的是,在出厂设置下只有轻微的偏蓝。因此,除了一些蓝色调之外,色彩还原得相当自然。

即使在低亮度下,屏幕也不会出现 PWM 闪烁,因此也推荐敏感用户使用。

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
23.2 ms ... rise ↗ and fall ↘ combined↗ 12 ms rise
↘ 11.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
36.8 ms ... rise ↗ and fall ↘ combined↗ 20.1 ms rise
↘ 16.7 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 48 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

性能、排放和电池续航时间 - 性能低下的廉价手机

GFXBench 曼哈顿压力测试
GFXBench 曼哈顿压力测试

使用 Helio G36小米选择了一个相当新的,但不是很强大的SoC。其实际性能仍可与更昂贵的手机媲美,但问题是许多基准测试都无法启动,甚至无法在Google Play商店中下载。因此,一些要求较高的应用程序很可能无法在手机上运行。

在日常使用中,您还不得不面对卡顿和加载时间过长的问题,这也是蹩脚的eMMC闪存造成的,但在这个价位的手机上可能是不可避免的。

至少,您不必面对高温问题:即使在长时间高负荷运行后,我们测得的最高温度也只有39.5 °C。由于3DMark Wild Life压力测试没有启动,我们使用GFXBench来查看SoC的性能在长时间负载后是否保持不变。事实上,情况并非如此;性能波动很大,在基准测试运行30次之后,性能比初始值低了20%。

上边缘的小扬声器有点不寻常,但绝不是摆放不当。它听起来高音很重,听音乐时并不能给人带来太多的愉悦。我们更喜欢通过3.5毫米端口或蓝牙传输到外部扬声器或耳机的声音。最必要的编解码器可用于无线声音传输,您甚至可以使用LDAC和aptX HD传输高保真声音。

小米红米A2的最大充电功率为10瓦。这意味着你必须耐心等待3个小时,直到显示屏上再次出现100%的电量,因为它拥有5000毫安时的大电池。我们的WLAN测试在不到15小时的时间内就耗尽了电池。这是一个不错的速度,因此如果您不是经常玩游戏,您应该可以轻松地度过一天。

小米红米A2是一款钱包轻松的手机,但你也需要良好的神经:系统运行速度相当慢,更复杂的应用程序往往根本无法运行。不能播放高清视频,Wi-Fi连接速度不是最快的,老式的microUSB接口已经非常令人讨厌。

尽管如此,它也有积极的一面,特别是考虑到其非常低的价格:机身做工精良,性能稳定,制造商承诺两年内定期更新,即使长时间使用手机也不会发热。

如果您的预算不多,或者只是想买一部便宜的第二部手机,您可以考虑一下红米A2:它可以满足您日常的一切需求。然而,您不应该期望系统流畅甚至快速。

如果您能多投资几欧元,您可能会考虑 摩托罗拉Moto E32s因为它拥有90赫兹的屏幕和速度更快的无线局域网模块。如果您正在寻找一款物美价廉的5G手机,您应该考虑一下 三星Galaxy A14 5G.

价格和供货情况

厂家直销在测试期间,红米A2所有三种颜色版本的售价均低于80欧元(约合80美元),我们的租赁商notebooksbilliger.de也收取相同的价格。

在美国,用户可以通过亚马逊订购该设备,价格约为80美元
