智能手机市场激烈竞争的一大优势是在每个价位都有可用的型号。如果您的预算非常有限，这并不重要。您仍然可以以大约 120美元(USD)的价格购买智能手机。我们已经很久没有评测过如此实惠的智能手机了，但现在是时候看看新的 realme C21了。阅读这篇评论，看看 120 美元会给你带来什么，智能手机：
realme C21：对谁有好处？
这款智能手机是以下方面的可靠选择：
- 想要以非常低的价格购买智能手机的人
- 需要智能手机一次充电可持续使用两天的用户
- 想要耐用智能手机的人
优点和缺点
realme C21有很多优点：
- 非常低的价格
- 坚固的制造质量，通过TÜV Rheinland认证(TÜV Rheinland)
- 出色的电池寿命
- 您可以同时使用两张SIM卡和一张 microSD
- 快速解锁（指纹传感器和人脸识别）
还有一些缺点需要考虑：
- 屏幕的亮度在户外表现不佳
- 它配备了Android 10而不是Android 11
- 包装盒中不包含耳机
- 过时的连接选项：仅Wi-Fi 4、无NFC、无USB-Type C等。
判决
很难对如此实惠的智能手机做出判断。在 120 美元时，制造商不得不做出许多妥协以保持一定程度的盈利能力。因此，不要期望 realme C21有什么壮观的东西。对于其微薄的价格，它是一款相当平衡的智能手机，在电池和质量部门中大放异彩。您不必每天都充电，只要您不运行要求苛刻的应用和游戏，它就可以胜任，并且其构建质量已通过TÜV Rheinland的耐用性认证。如果您的预算非常有限，realme C21物超所值。

在较小的盒子下方，您可以看到装在保护袋中的智能手机本身，在智能手机下方，您可以找到USB数据线和标准 10W 充电器，没有任何快速充电支持。这款智能手机非常实惠，realme 已经最大限度地降低了成本，并决定不捆绑耳机。如果您问我们，这是一个不足为奇的决定。
你在盒子里发现了什么
realme C21是一款包装精美的产品。它的盒子只有您使用智能手机所需的基础知识，并且不包括耳机。(The realme C21 is a beautifully packaged product. Its box has only the basics you need to use your smartphone, and it doesn’t include a headset.)
设计和建造质量
realme C21是一款外观标准的 6.5 英寸圆角智能手机。它具有以下尺寸 6.50 x 3.01 x 0.35 英寸或 165.2 x 76.4 x 8.9 毫米。它比我们最近测试的realme 8 5G略大和重：realme C21的重量为 6.70 盎司或 190 克，而 realme 8 5G 的重量为 6.5 盎司（185 克）。这款智能手机有两种颜色可供选择：十字蓝(Cross Blue)和十字黑(Cross Black)。我们测试了蓝色变体。

- 跌落、磨损等十种日常使用测试场景
- 七种极端环境测试场景，包括超极端温度、极端湿度、电压波动、按键寿命、静电、气压
- 六个组件可靠性测试场景。
虽然 realme C21是由塑料制成的，但它确实感觉很好，而且很坚固，所以这个认证可能不仅仅是营销话题。
硬件规格
该显示器使用IPS LCD面板，峰值亮度为 400 尼特和 720x1600 像素。屏占比为80.8%，密度为270 ppi。如果您想了解更多关于 ppi 及其含义的信息，请阅读：什么是 PPI，它是否重要？(What is PPI and does it matter?).
开启realme C21
realme C21由低端联发科技 Helio G35(MediaTek Helio G35)片(Chip)上系统提供支持，其中四个 Cortex-A53 内核以 2.3 GHz运行，另外四个以 1.8 GHz运行。图形芯片是PowerVR GE8320，它非常适合多媒体应用，但在游戏方面表现不佳。在内存(RAM)方面，realme C21有 3GB 和 4GB 两种可选，而存储则可以是 32GB 或 64GB。我们测试了具有 4GB RAM和 64GB 存储空间的变体，我们建议您购买相同的版本以获得这款手机的最大性能。

realme C21(C21)上的主摄像头系统
一个问题是 realme C21仅适用于(C21)Wi-Fi 4等较旧的无线网络标准。不支持在 5 GHz频段上使用(GHz)Wi-Fi，仅支持 2.4 GHz频率。在我们看来，这是一个重大限制，realme 应该提供Wi-Fi 5 连接。显然，对于如此实惠的智能手机，也没有 5G 移动连接。
realme C21 只连接 Wi-Fi 4
但是，realme C21 确实支持蓝牙 5(Bluetooth 5)、GPS和FM 收音机(FM-radio)（如果您自己购买耳机）。此外，它具有 microUSB 2.0 端口而不是 USB-Type C。在传感器方面，它包括以下内容：加速度计、指纹传感器、接近传感器、光传感器和指南针。不幸的是，缺乏NFC 支持。(NFC support)

realme C21 review: the ultra-low-budget smartphone! -
One big plus of thе fierce competition in the smartphone market іs the range of models available at everу price pоіnt. It doesn’t mattеr if yоur budget is a very modest onе. You can still get yourself a smartphone at about 120 USD. We haven’t reviewed such an affоrdablе smartphone for a very lоng time, but now it is time to tаke a look at the new realme C21. Read this review and see what 120$ will get you, smartphone-wise:
realme C21: Who is it good for?
This smartphone is a solid choice for:
- People who want a smartphone at a very low price
- Users who need a smartphone that can last for two days on a single charge
- People who want a durable smartphone
Pros and cons
There are many good things about the realme C21:
- Very low price
- Solid build quality, certified by TÜV Rheinland
- Excellent battery life
- You can use two SIM cards and a microSD simultaneously
- Fast unlocking (fingerprint sensor and face recognition)
There are downsides to consider as well:
- The screen’s brightness is underwhelming outdoors
- It comes with Android 10 instead of Android 11
- No headset included in the box
- Dated connectivity options: only Wi-Fi 4, no NFC, no USB-Type C, etc.
Verdict
It is tough to give a verdict for a smartphone this affordable. At 120$, the manufacturer had to make many compromises to keep some degree of profitability. Therefore, don’t expect any spectacular things from the realme C21. For its meager price, it is a reasonably well-balanced smartphone that shines in the battery and build quality departments. You won’t have to charge it every day, it is competent as long as you don’t run demanding apps and games, and the build quality is certified by TÜV Rheinland for its durability. If your budget is very limited, realme C21 offers a good bang for your buck.
Unboxing the realme C21 smartphone
The realme C21 smartphone comes in a small yellow cardboard box with a minimalistic look. On the top and the sides, you see only the name of the smartphone you just bought. There are some stickers with information about the hardware inside this device, its IMEI number, serial number, and other details on the bottom of the box.

When you open the box, you see another smaller box with a welcome message on it. This smaller box contains two leaflets with information about your smartphone and how to set it up, as well as the pin for ejecting the SIM tray.
Unboxing the realme c21
Beneath the smaller box, you see the smartphone itself in a protective bag, and beneath the smartphone you find a USB cable and a standard 10W charger, without any fast-charging support. This smartphone being so affordable, realme has cut costs to the maximum and decided not to bundle a headset. An unsurprising decision if you ask us.
What you find inside the box
The realme C21 is a beautifully packaged product. Its box has only the basics you need to use your smartphone, and it doesn’t include a headset.
Design and build quality
The realme C21 is a standard-looking 6.5-inch smartphone with rounded corners. It has the following dimensions 6.50 x 3.01 x 0.35 inches or 165.2 x 76.4 x 8.9 mm. It is slightly larger and heavier than the realme 8 5G that we recently tested: realme C21 weighs 6.70 oz or 190 grams vs. 6.5 oz (185 grams) of the realme 8 5G. This smartphone is available in two colors: Cross Blue and Cross Black. We tested the blue variant.
The realme C21
The back of the smartphone is made of plastic, and it has an attractive striped texture that also helps with the grip. When you hold it in your hand, you don’t feel the smartphone slip. On the back, you find the camera system, the fingerprint sensor, the realme logo, and the phone’s only speaker.

When it comes to build quality, realme brags about this phone being the first to pass the TÜV Rheinland smartphone certification testing. The certification process involved 23 major tests:
- ten daily use test scenarios, such as drop, wear and tear
- seven extreme environment test scenarios, including super extreme temperature, extreme humidity, voltage fluctuation, button life, static electricity, and air pressure
- six component reliability test scenarios.
While the realme C21 is made from plastic, it does feel well reinforced and quite solid, so this certification may not be just marketing talk.
Hardware specifications
The display uses an IPS LCD panel, with a peak brightness of 400 nits and 720x1600 pixels. The screen to body ratio is 80.8%, and the density is 270 ppi. If you want to know more about ppi and what it means, read: What is PPI and does it matter?.
Turning on the realme C21
The realme C21 is powered by a low-end MediaTek Helio G35 System on a Chip with four Cortex-A53 cores running at 2.3 GHz and another four at 1.8 GHz. The graphics chip is a PowerVR GE8320 that is well suited for multimedia applications but underwhelming for gaming. In terms of RAM, the realme C21 is available with both 3GB and 4GB, while the storage can be 32GB or 64 GB. We tested the variant with 4GB of RAM and 64 GB of storage, and we recommend you buy the same version to get the maximum performance possible from this phone.
The SoC inside the realme C21
Luckily, the storage can be increased with the help of a microSD card. Also, an upside is that you can use the phone with two SIM cards and a microSD card simultaneously. We expect many users to appreciate this feature.
realme C21 takes two SIMs and a microSD card
The non-removable Li-ion battery has a generous capacity of 5000 mAh, charging at 10W. As expected for a phone at this price range, there is no support for wireless charging built-in.
The realme C21 has a wide selfie camera in the middle of the screen with 5 Megapixels and an aperture of f/2.2. The main camera system on the back has three cameras:
- A primary wide camera with 13 Megapixels, f/2.2 aperture, a 5P lens, and 4x digital zoom.
- A 2MP macro camera with an aperture of f/2.4 and a 3P lens.
- A depth of field 2MP camera, with an aperture of f/2.4.
There’s also a flash available for night photography. The main camera system can record videos in 1080p or 720p resolution at 30 frames per second. There’s no video stabilization available.
The main camera system on the realme C21
One issue is that the realme C21 works only with older wireless network standards like Wi-Fi 4. There’s no support for using Wi-Fi on the 5 GHz band, only the 2.4 GHz frequency. In our view, this is a significant limitation, and realme should have provided Wi-Fi 5 connectivity. Obviously, for a smartphone this affordable, there is no 5G mobile connectivity either.
realme C21 connects only to Wi-Fi 4
However, realme C21 does have Bluetooth 5 support, GPS, FM-radio support (if you buy yourself a headset). Also, it features a microUSB 2.0 port instead of a USB-Type C. In terms of sensors, it includes the following: an accelerometer, a fingerprint sensor, a proximity sensor, a light sensor, and a compass. Unfortunately, NFC support is lacking.
