外壳和设备 - 制造不完美
更强的动力总是受欢迎的，不是吗？尤其是以合理的附加费用获得它的时候。Teclast T50 Pro 的价格甚至不到 300 欧元，而且在网上已经有大幅折扣，您还可以获得额外的优惠。
与 Teclast T50的关系不一定一眼就能看出来：虽然 T50 Pro 也有一个稳定的金属外壳，但它的扬声器和按键位置不同，而且背面还有一个带闪光灯和第二个镜头的相机模块。
机身可能会有些扭曲，甚至在一角有些跳开，这降低了质量印象。除此之外，这款平板电脑的制造质量还算不错。尽管屏幕尺寸相同，但它比 Teclast T50 更方便，重量也轻了 30 克。 Teclast T50.
除了用于存储数据的 256 GB UFS 2.2 闪存外，还有 8 GB 工作内存，也不算太紧张。此外，还有一个 microSD 插槽可用于扩展存储空间。这款阅读器的整体速度并不是特别快，但在同价位产品中，它与我们参考的 microSD Angelbird V60 相比还是相当快的。

通信、软件和操作 - 无广告的纯Android
除了充足的存储空间，Teclast 平板电脑还提供一个 SIM 卡插槽，甚至可以通过 4G 网络使用移动互联网。虽然可用的频率不多，但对于欧洲和一些热门旅游目的地来说应该足够了。在几项随机测试中，接收质量还算不错，但与昂贵的智能手机相比，还不在一个档次上。
Teclast T50 Pro 还搭载了 WiFi 5，在我们使用参考路由器华硕 ROG Rapture AXE11000 进行的测试中，Teclast T50 Pro 的传输速率相当稳定，大约在 300 到 380 MBit/s 之间，这在同类产品中很常见。
平板电脑上安装了 PureAndroid 13，安全补丁是从 2023 年 5 月开始的，因此在测试时还不算太旧。我们无法理解的是，制造商没有对 Widevine 进行认证，而 Teclast T50却通过了认证。因此，目前还无法从主要平台流式传输高清或 4K 内容。幸运的是，没有预装广告软件。
屏幕是 60 Hz 面板，因此操作时不时会感觉有点迟钝，尤其是如果你以前使用过 120 Hz 屏幕的手机等。平板电脑没有指纹传感器，但可以通过面部识别解锁。这种方法非常可靠、快速，但由于使用的是二维数据，所以不是很安全。

照相机 - 现在带闪光灯
虽然 T50 Pro 的相机传感器与 Teclast T50有一个重要区别：现在背面有一个 LED 闪光灯，可以照亮黑暗的场景。背面的深度传感器就不那么重要了。它看起来像第二个摄像头，但只能为人像模糊效果提供额外数据。
背面的 2000 万像素摄像头拍摄的照片相当暗，动态效果相对较少。不过，图像清晰度相当不错，仍能看到一些细节。在光线非常暗的情况下，特别明显的是，摄像头在非常亮和非常暗的区域都过度疲劳。
视频最高可录制 1440p 和 30 fps。自动对焦常常显得力不从心，反应相当缓慢。
前置 800 万像素摄像头用于自拍。在光线充足的情况下，拍摄的照片亮度尚可，但看起来颗粒感较强，细节对比度不足。

显示屏 - Teclast T50 Pro 的颜色变得更深了
Teclast T50 Pro 的 IPS 显示屏分辨率为 2000 x 1200 像素，略高于全高清标准。遗憾的是，在我们的测试中，屏幕比 Teclast T50的平均亮度仅为 344 cd/m²，难以满足室外使用的要求。
60 Hz 的滚动也不太流畅，但至少我们没有注意到任何 PWM。
在使用分光光度计和软件 CalMAN 进行的测试中，我们还发现了严重的偏蓝现象，这种现象会伪造色彩，使画面更冷。屏幕的对比度也不高。

性能、排放和电池寿命 - 功率和耐用性
使用 Helio G99Teclast 在这个价位采用了功能强大的 SoC。无论是在 CPU 还是 GPU 基准测试中，其性能都大大超过了 Teclast T50甚至 三星Galaxy Tab A8 2022.红米 红米平板电脑实际上采用的是相同的 SoC，也能提供相当高的性价比。
在日常使用中，你通常可以流畅地浏览 T50 Pro，但 90 Hz 的屏幕肯定会让系统使用起来更加流畅。此外，T50 Pro 还支持更多现代图形 API，因此大多数游戏都能在平板电脑上运行。
在长时间负载情况下，最高温度仅为 35 °C，并不明显。在运行 20 次 3DMark Wild Life 之后，性能也与测试开始时保持在同一水平。
4 个扬声器听起来有点高音偏重，声音也不是特别大，但如果你想听懂视频中的语音或试听流行歌曲，它们已经足够了。不过，要享受真正的音频效果，建议使用可通过 USB-C 或蓝牙连接的外置扬声器或耳机。后者有许多编解码器可供选择：除了标准的 SBC、AAC、LDAC 和 aptX 外，还有更高质量的变体，如 LHDC 或 aptX HD。
Teclast T50 Pro 配备了 8,000 mAh 电池，电池容量甚至比 T50的电池容量。这是一项了不起的成就。在我们的 Wi-Fi 测试中，T50 Pro 的续航时间也比其便宜的兄弟产品要长得多。我们测得的时间为 17:26 小时，即使在高强度使用的情况下也能轻松维持一天。该设备的充电功率为 18 瓦，需要 3 个多小时才能在电池电量耗尽时显示出 100% 的充电状态。遗憾的是，它不支持无线充电。
