机箱和规格 - 轻质金属机箱
我们最近参观了 Teclast P26T这款平板电脑以塑料机身和超低价格吸引消费者。本次评测的 Teclast P30T 价格略高。它已配备Android 14 和金属机身，但使用与 P26T 相同的 SoC。
机身相当坚固，但也不宜用力按压。材料之间的接缝干净利落。Teclast P30T 是一款非常轻巧的 10.1 英寸平板电脑，重 444 克（约 1 磅）。显示屏边框较宽，这让人感觉平板电脑的设计有些过时。另一方面，边框让你可以轻松握住平板电脑，不用担心误触触摸屏。唯一的配色是太空灰。
Teclast 声称该设备的内存高达 10GB，但不要被这一信息误导。P30T 只有 4 GB 的物理内存，但允许在内部存储中创建一个最大 6 GB 的文件作为虚拟内存使用。这比专用内存要慢得多，因此只能被视为一种临时解决方案。鉴于该平板电脑的性能相对较低，它可能也不会带来什么好处。
该设备拥有 128 GB 的存储容量，这在同价位产品中算是不错的了。您还可以使用 microSD 读卡器扩展总存储容量，事实上，读卡器的速度也相对较快。遗憾的是，由于 CPDT Benchmark 拒绝在该平板电脑上运行，我们无法向您展示任何相关结果。
平板电脑左上角有一个 3.5 毫米音频插孔。

连接、软件和操作 -Android 14 on the Teclast tablet
你只能使用 Wi-Fi 上网，因为这款平板电脑没有蜂窝网络连接。制造商声称该产品拥有 Wi-Fi 6，SoC 也向我们的硬件分析应用程序报告了这一点。不过，在我们使用参考路由器（华硕 ROG Rapture AXE11000）进行的测试结果中并没有反映出这一点。Teclast P30T 的数据传输速度约为 280 至 370 Mbit/s，与我们通常在配备 Wi-Fi 5 的平板电脑上看到的速度完全一致。
该公司称，P30T 支持最新的蓝牙 5.4。但我们对此也表示怀疑，认为该设备更有可能使用蓝牙 5.2。
该平板电脑无法使用卫星网络识别位置，但可以借助谷歌定位服务（Google Location Services）来大致确定位置，该服务使用 Wi-Fi 网络数据库来实现这一功能。
该软件基于Android 14。值得庆幸的是，Teclast 还决定提供原版Android 系统，不预装任何第三方应用程序。另一个好处是该平板电脑支持 Widevine L1，这意味着你可以高清观看主要流媒体服务的内容。该公司尚未给出任何更新承诺。用户只能希望获得安全和软件补丁。在撰写本文时，上一次安全更新的日期是 2023 年 11 月，因此已经有些过时了。
触摸屏的最大触摸采样率为 120Hz。它使用起来很可靠，但肯定有一些平板电脑对输入的反应更灵敏。平板电脑上没有指纹扫描仪。在生物识别认证方面，只能通过前置摄像头使用二维人脸识别。在光线充足的条件下，人脸识别可以准确可靠地工作，但在有阴影的地方，系统就会开始出现问题。

照相机 - 更多用于紧要关头
Teclast 在机身背面安装了两个摄像头，但实际上只有一个用于拍照。另一个摄像头只是在人像模式下拍摄时提供额外的背景模糊数据。
主摄像头的分辨率仅为 500 万像素，拍出的照片像素很低，细节很少。在光线条件良好的情况下，只要亮度差别不大，照片就能像快照一样清晰。否则，亮部会曝光过度，而暗部则几乎没有细节。
同样，这款相机更适合在光线不足、反差较大的情况下使用。在我们的弱光测试照片中，它几乎没有捕捉到直射光圈以外的任何额外细节。在我们的摄影实验室，在明亮的工作室灯光下，图像看起来颗粒感很强，细节几乎无法辨认。图像还带有明显的红色色调。仅 1 lux 时，相机就无法再现任何图像内容。
前置摄像头的分辨率仅为 200 万像素，自拍质量相当差，而且只能在光线充足的情况下拍摄。

显示屏 - 低分辨率，但亮度适当
显示屏的分辨率为 1,280 x 800。因此，考虑到其相对较大的 10.1 英寸尺寸，你可以看到该面板与更高分辨率屏幕在图像质量上的明显差异：图像显得不那么清晰，对角线边缘在仔细观察时会有明显的锯齿。
此外，显示屏还显得有些暗淡，因此第一眼看上去对比度就不高。我们在使用分光光度计和 CalMAN 软件进行的测试中证实了这一点。测试结果显示，灰色色调带有明显的绿色色调，而强烈的色调则显得过于暗淡。
尽管如此，至少对于这个价位的平板电脑来说，屏幕的亮度还算不错：我们测得的平均峰值亮度为 310 cd/m²。这与其他设备大致相当，比 Teclast P26T.尽管如此，在明亮的户外使用时，屏幕可能还是太暗了。
在最低亮度设置下，我们没有检测到任何 PWM。

性能、排放和电池寿命 - 作为瓶颈的 SoC
至于性能，你不应该对这款经济型平板电脑抱有太高期望。它采用与 全志 A523SoC Teclast P26T.该芯片需要使用八个 Cortex-A55 内核，而这些内核通常用于处理器的高能效部分。此外，SoC 采用的是过时的 22 纳米工艺，这意味着它的能效很低。
因此，即使是在执行日常任务或使用菜单时，偶尔出现卡顿也是常有的事。此外，该设备的基准测试结果明显不如其他公司生产的同价位平板电脑。图形性能也很差。存储部件（使用本已缓慢的 eMMC 闪存）显然受到 SoC 存储控制器的更大影响。因此，用户使用的系统响应速度相当慢，加载时间很长。
鉴于 SoC 的低性能，在我们的测试过程中，机箱温度高达 40.5°C（104.9°F），着实令人吃惊。虽然这不是一个临界水平，但你还是能感觉到。至少，SoC 可以在长时间负载下保持性能：3DMark 压力测试显示，在基准测试运行 20 次后，性能仅有轻微下降。
平板电脑配备了两个扬声器，这意味着它能提供轻微的立体声效果。扬声器的音量相当大，但听起来非常刺耳--非常适合语音和人声，但由于缺乏低音，不利于声音的饱满度。因此，该音响系统更多是为了让您快速聆听音乐曲目。要充分享受音乐，您应该通过蓝牙或 3.5 毫米音频插孔将扬声器或耳机连接到设备上。无线音频有多种编解码器可供选择，包括 SBC 和 AAC 等标准编解码器，以及 LDAC 和开源 Opus 等高保真编解码器。
电池容量为 6,000 mAh，大小适中。但由于其制造工艺落后，SoC 在电池续航时间方面存在问题：在 Wi-Fi 测试中，我们只能从平板电脑上获得 7 小时 33 分钟的续航时间。这几乎只是 联想 Tab M10 Gen 3或 三星Galaxy Tab A7 LTE 2022的一半。
主要在家中使用 P30T 的用户可能随时都会在身边准备一个电源插座，但与其他设备相比，这款平板电脑需要更频繁地充电。此外，给电池充电需要很长时间：你应该预留四个多小时才能充满电。

Pros

评价 - 价格便宜，但使用起来并不总是那么愉快
Teclast P30T 是一款入门级平板电脑，有时不到 100 欧元（108 美元）就能买到。它拥有轻巧的金属机身、亮度尚可的无 PWM 显示屏以及通过 Widevine 认证的Android 14。
尽管如此，显示屏分辨率低，CPU、GPU 和内存性能弱，以及软件更新的不确定性，都影响了我们对这款经济型平板电脑的喜爱。
摄像头更像是权宜之计，如果你想拍出像样的照片，在很多情况下几乎无法使用。含糊其辞的内存大小和也许正确的支持 Wi-Fi 和蓝牙版本信息也无法让人产生信心。SoC 的能效不高，巨大的电池只能提供短暂的续航时间。
这是一个遗憾，因为 Teclast 通过价格略高的 M 和 T 系列设备证明，花很少的钱就能买到很好的配置。Teclast P30T 通过提供大容量存储空间和 microSD 插槽，也在这方面脱颖而出。
虽然 Teclast P30T 也存在一些问题，但如果你打算主要在家里使用平板电脑，并希望获得大容量存储空间，那么它仍不失为一款物美价廉的产品。
联想 联想平板电脑 M10 第 3 代也采用了金属机身，但你需要为此支付少量的溢价。廉价平板电脑的另一个例子是 Blackview Tab 80，它甚至拥有 LTE 功能。
