三星Galaxy Tab A9 评测--配备 GPS、LTE 和 4 年更新的实用入门级平板电脑

经济实惠,结构紧凑。

Galaxy Tab A9 是一款小巧的平板电脑,为预算有限的用户提供长时间的软件支持。在我们的评测中,这款售价 170 欧元(约合 160 美元)的三星平板电脑以其明亮的显示屏和全面的功能给我们带来了惊喜。但请继续阅读,看看这款平板电脑不适合哪些人。

三星Galaxy Tab A9 平板电脑评测

随着 Tab A9 的推出,三星调整了面向预算有限的消费者的平板电脑阵容。继 Tab A8不仅尺寸略有缩小(屏幕对角线尺寸为 8.7 英寸),而且价格也有所降低。Galaxy Tab A9 的建议零售价为 179 欧元(159 美元)起,这意味着其基本配置比上一代产品便宜约 50 欧元(70 美元)。不想缩小尺寸的 Tab A8 用户仍然可以在Galaxy 中选择新的 Plus 机型作为 10.1 英寸的替代品。

这一次,三星还考虑到了年轻用户。Tab A9 儿童版配有一个保护套和一支触控笔,并采用了经过修改的 One UI,以简化儿童对平板电脑的使用,帮助家长更轻松地监控孩子的数字活动。不过,儿童版尚未在德国上市。

在美学方面,Galaxy Tab A9 与前代产品的相似之处是显而易见的。其设计非常像 Galaxy Tab A7 LiteTab A8背面的摄像头模块有所改动。尽管如此,8.7 英寸 TFT 面板周围的边框已大大缩小。81.7% 的屏占比对于这个价位的设备来说很有吸引力,而且比诺基亚 T10 的屏占比更高效。 诺基亚 T10(72.4%)相比要高效得多。

虽然Galaxy Tab A9 的价格非常实惠,但由于采用了纤薄的金属机身,因此在设备的手感方面没有任何牺牲。三星平板电脑的重量也很轻,只有 332 克(0.71 磅),单手即可轻松握住。机身有三种配色(石墨色、银色和深蓝色)可供选择。由于采用了磨砂表面,指纹问题不大,但仍清晰可见。

Galaxy Tab A9 的做工令人印象深刻。此外,小巧的机身尺寸让人感觉坚固耐用。

规格 - 三星Galaxy Tab A9,带 3.5 毫米音频插孔

就规格而言,Galaxy Tab A9 绝对为移动使用提供了有趣的功能。该设备配备了 3.5 毫米音频插孔、蓝牙 5.3 和包括 eSIM 支持在内的 4G 双卡选项。共有四种型号可供选择:

Galaxy Tab A9 Wifi| 64 GB| 4 GB RAM| €179.00

Galaxy Tab A9 LTE| 64 GB| 4 GB RAM| €219.00

Galaxy Tab A9 Wifi| 128 GB| 8 GB RAM| €229.00

Galaxy Tab A9 LTE| 128 GB| 8 GB RAM| €269.00

我们的仅 Wi-Fi 版内置 64 GB 存储空间。但减去用于操作系统的空间后,可用存储空间只有约 43 GB。如果您需要更多空间存储视频或照片,可以通过 USB OTG 使用附件(如优盘),或在混合插槽中插入 microSD 卡。外置存储设备可用于存储媒体文件(视频或音乐),但不能用于存储应用程序。

如你所料,三星只为Galaxy Tab 9 配备了一个迟缓的 USB 2.0 端口,无法实现高速数据传输或通过线缆输出视频。在我们使用 M.2 固态硬盘(三星 980 Pro)进行的拷贝测试中,传输速度约为 29 MB/s。该设备支持 exFAT 和 NTFS(微软系统首选)。不过,后者只能用于读取操作。

在我们的 JPEG 拷贝测试中,尽管Galaxy 平板电脑没有充分发挥 Angelbird AV Pro 60 的潜力,但它与我们的参考卡一起实现了非常令人满意的传输速率。Tab A9 在跨平台磁盘测试中同样表现出色。

软件 -Galaxy Tab,支持长期更新

在评测期间,三星在Android 13 上覆盖了 One UI 5.1,并提供了 2023 年 8 月的安全更新。这款入门级平板电脑的一大优势是三星提供的相对较长的产品保护期。在这个价位段,没有其他制造商能提供两代 UI 和Android OS 升级,以及四年按季度推出的安全更新。尽管如此,考虑到最后一个安全补丁的日期是 2023 年第三季度,三星似乎并不总是能兑现他们的承诺。

尽管 Tab A9 无法访问三星的 DeX 用户界面,但它支持内部 Knox Vault 平台。这意味着这款入门级平板电脑可以使用三星的安全和隐私仪表板,并在发送内容之前对其进行加密。Galaxy Tab A9 还集成了公司的生态系统,因此可以在以下设备之间进行无线连接 三星Galaxy 设备之间的无线连接。.

连接和全球导航卫星系统 - 配备 GPS 的三星平板电脑

Tab A9 的内置 Wi-Fi 模块支持 IEEE 802.11a/b/g/n/ac 标准,因此只能在 2.4 GHz 和 5 GHz 频段上运行。在我们的家庭网络中,使用 Wi-Fi 5 标准和我们的参考路由器(华硕 ROG Rapture GT-AXE11000)可以达到 350 MBit/s 以上的传输速率,在这个价位的产品中还算不错。提供的速度并不高。不过,发送和接收速度非常稳定。

我们的评测机没有蜂窝网络功能。虽然有 LTE 版本,但 Helio G99 不支持较新的 5G 标准。

幸运的是,所有型号的 Tab A9 都可以用于导航,因为即使是 Wi-Fi 版也配备了 GPS 模块。定位是通过 GPS、伽利略、北斗和格洛纳斯卫星系统(均为单波段)完成的。在室外定位精度可达两米。

在实际测试中,我们带着这款平板电脑骑车,并携带 Garmin Venu 2 进行比较。作为一款入门级平板电脑,A9 的定位精度之高令人惊讶。虽然记录的路径与实际路线之间存在一些差异,但这些差异微乎其微。如果您正在寻找一款大型 GPS 设备用于驾驶,那么配备 A-GPS 的 4G 版本可能会取得更好的效果。

摄像头 - 单摄像头设置

在正面,Tab A9 配备了一个低分辨率的 200 万像素摄像头,固定焦距位于显示屏上方。这意味着除了用于视频通话外,你不应对前置摄像头抱有太多期望。自拍看起来非常柔和,曝光也不稳定。由于分辨率较低,细节还原不是入门级平板电脑的强项。

后置 800 万像素摄像头具有自动对焦功能,这在这个价位的平板电脑上并不常见,有时甚至会出现以下情况 在中高档平板电脑上甚至会缺失。.不过,它的图像清晰度对于拍摄日常使用的文档和笔记来说还是比较合适的。照片缺乏活力,对比度较低;色彩偶尔会显得暗淡。

后置摄像头可以 30 帧/秒的速度拍摄 1080p 视频,而自拍摄像头只有高清选项。

配件和保修 - 不包括充电器

三星Galaxy Tab A9 平板电脑评测

在配件方面,三星只提供了一条 USB 线(Type C 到 C)、一个用于打开卡槽的小工具和文档。如果你想要一个保护套,可以选配一个可调节角度的Book Cover(零售价43欧元,约合46美元)。尽管这款 8.7 英寸设备在开箱时没有预装保护膜,但三星也没有为 Tab A9 提供任何屏幕保护膜。

三星为这款经济型平板电脑在德国提供 24 个月的保修服务。您还可以添加 Care+ 保险套餐,保修期为 12 至 24 个月(零售价:24 欧元起,合 26 美元)。保修条款和条件可能因地区而异。

输入设备和操作 - 配备面部解锁功能的三星Galaxy Tab A9

Tab A9 的电容式触摸屏在检测手指输入时不会出现任何明显的延迟,但不兼容 S Pen。内置的 TFT 面板仅支持 60Hz 的刷新率。因此,动画和滚动的流畅度较差,感觉比 90Hz 的同类平板电脑(如红米 Pad SE)更不流畅。 红米 Pad SE.

生物识别安全是通过前置摄像头进行人脸识别,但使用的是不安全的二维方法。在光线良好的条件下,解锁过程能够可靠地工作。人脸数据的注册仅限于一个用户。平板电脑没有指纹识别器。

Galaxy Tab A9 的屏幕对角线尺寸为 8.7 英寸,分辨率为 1,340 x 800 像素,相当于 179 PPI 的像素密度。因此,TFT 显示屏不会让内容看起来非常清晰,也不会让那些对屏幕非常挑剔的人欣喜若狂。

三星平板电脑在亮度方面做得更好。在我们的测量中,TFT 面板在显示全白图像时的峰值亮度为 486 cd/m²。APL 18 测量更能代表日常使用情况,亮度并没有大幅提高,但这对于采用 LCD 技术的平板电脑来说是正常的。

我们在 Tab A9 上没有发现任何屏幕闪烁(PWM)现象。尽管如此,LCD 的典型弱点(阴影、边缘背光不均匀)在三星设备上还是比较明显。即使在白天,在暗色背景下也能明显感觉到背光渗出的影响(见 Tab A9 上的视频截图)。

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 8746 (minimum: 5 - maximum: 343500) Hz was measured.

我们使用 CalMan 分析软件对 IPS 面板的色彩校准进行了评估。我们测量的 sRGB 色域的 Delta E 值显示,对于这个价位的平板电脑来说,色彩和灰度再现的偏差量都是可以接受的。不过,Tab A9 并没有达到目标水平(Delta E < 3)。因此,你会很容易注意到显示颜色和参考颜色之间的差异,尤其是白色和红色。灰阶还带有淡淡的蓝色调,但我们对此并不感到困扰。

TFT 面板的黑度为 0.35 cd/m²,对比度约为 1,400:1。入门级平板电脑在色彩配置方面受到限制。Tab A9 的 One UI 仅提供一种色彩模式。你甚至无法调节色温。

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.

Tab A9 在户外给人的印象并不自信,因为即使在阴天,玻璃表面的反光也会明显限制显示屏的可读性。不过,Tab A9 的亮度足以满足在室内使用的需求。

TFT 面板的可视角度令人信服。从锐利的角度观看显示屏时,也只有适度的典型亮度衰减。

性能 - 配备联发科 SoC 的三星平板电脑

Galaxy Tab A9 的引擎盖下搭载了 联发科 Helio G99配备两个 Cortex-A76 性能内核。与同类紧凑型平板电脑相比,这款于 2022 年发布的芯片组在我们的 CPU 测试中表现出色,在 Geekbench 中的单核和多核分数都很高。不过,那些对三星平板电脑感兴趣的人不应该被这些结果误导,因为其性能仍然被认为是非常低的。在 10 英寸或更大屏幕的平板电脑中,Helio G99 是这一价格区间非常常见的 SoC。

对于这个价位的平板电脑来说,Tab A9 的内部存储速度确实很快。虽然三星没有提供确切的规格,但根据 AndroBench 的得分,它很可能使用了 UFS 2.2 标准。竞争对手的 eMMC 闪存是目前智能手机和平板电脑中使用的最慢的存储技术。

游戏 - 三星Galaxy Tab A9 可达到 60 帧/秒

为了更好地评估 Mali-G57 MP2在日常使用中的图形性能,我们借助GameBench应用程序。在Galaxy Tab A9 上无法流畅运行要求苛刻的游戏,如《源氏冲击》。在低图形设置下,我们测得的平均帧率为 37 帧/秒,但帧数下降严重。一旦将设置调高,我们得到的平均帧数为 22 fps,但视觉效果很差。

轻度游戏的情况则有些不同。在高清设置下,Tab A9 在《PUBG Mobile》中的帧数达到了 30 帧,但这款入门级设备无法选择最高图形设置(UHD)。可选的 90 帧模式也是如此。不过,A9 在最低设置下也能达到 40 帧/秒。

温度

Galaxy Tab A9 的机身在日常使用中几乎不会发热。即使在重负载情况下,例如在进行 Burnout Benchmark 测试时,我们测量的平均温度也只有 33°C (91.4°F)。我们使用 3Dmark 的电池测试来评估平板电脑内部的散热性能。Wild Life 压力测试毫不费力地运行,稳定性超过 98%。因此,即使在持续负载的情况下,我们也无法使 Tab A9 出现明显的节流现象。

发言人

Galaxy Tab A9 配备了两个扬声器,每个额定功率为 1 瓦。杜比全景声(Dolby Atmos)认证系统可提供合格的立体声音频,音量高达 86 分贝。三星平板电脑的高音相当线性,但播放粉红噪声时会发现中音有急剧上升的趋势。低音不明显。

使用 3.5 毫米音频接口或蓝牙连接无线扬声器或耳机,可以获得更好的播放质量。根据我们的测量,音频输出的噪音水平并不完美,但信噪比为 78.5 dBFS,非常令人满意,尤其是考虑到其价格。在蓝牙编解码方面,Galaxy 平板电脑仅支持 SBC、AAC、aptX、aptX HD 和 LDAC。这意味着,除了必须支持的 SBC 外,你还能为大多数耳机找到合适的编解码器。即便如此,该设备提供的编解码器种类并不多。

耗电量

Galaxy Tab 9 配备 5100 毫安时电池,可通过 USB-C 接口以最高 15 瓦的功率充电。我们使用电源箱(PD 3.0,最大功率 100 瓦)在大约 2.5 小时内就能为平板电脑充满电。

平板电脑空闲时的耗电量各不相同,从非常低的 0.7 瓦到相当可观的 3 瓦不等。在负载情况下,Tab A9 的耗电量比 联想 Tab M8.尽管如此,由于我们最近改用了另一种基准测试工具(Burnout Benchmark)进行负载测试,因此无法与稍早之前的评测进行直接比较。

三星Galaxy Tab A9 的评价

评论:三星Galaxy Tab A9。
评论:三星Galaxy Tab A9。

Galaxy Tab A9 凭借其轻便小巧的设计从众多入门级产品中脱颖而出,这意味着能与之竞争的替代产品非常有限。联想 联想 Tab M8就是一个值得竞争的例子。不过,这家中国制造商的这款入门级平板电脑仍然使用了 较弱的 SoCHelio G99Galaxy Tab A9 的性能要弱一些。

通过Galaxy Tab 9,三星创造出了一款外形小巧、整体性能稳定的产品。

Galaxy Tab A9 的一大优势是相当长的更新支持。三星承诺每季度提供四年的安全更新和补丁(理论上)。尽管价格实惠,但我们还是希望在 One UI 中看到更多关于显示屏色彩校准的自定义功能,就像在中档三星平板电脑中一样。 中档三星的中端产品一样。此外,60Hz 的最大刷新率和指纹传感器的缺失也对日常使用造成了负面影响。

遗憾的是,Tab A9 也不支持三星自己的 S Pen。因此,它不太适合希望获得一款用于书写备忘录和记笔记的小巧平板电脑的用户。那些怀念三星平板电脑手写笔功能的用户可以关注 联想平板电脑 M10 Plus作为入门级平板电脑的替代品,但这是以紧凑设计为代价的。

价格和供应情况

三星Galaxy Tab A9 的起始零售价为 179 欧元(159 美元)。您甚至可以在亚马逊等在线零售商处以更低的价格买到。
