三星Galaxy Tab A7 Lite平板电脑评测:非常实惠的迷你版三星平板电脑

稀有价值。 三星的Galaxy Tab A7 Lite是一个异类:罕见的8英寸平板电脑之一,起价169欧元(约合人民币199元),还可以加价30欧元(约合人民币35元)购买LTE。Android-11平板电脑配备了来自联发科的八核SoC,32GB的存储空间,带有杜比全景声的扬声器和家庭友好的儿童模式。我们的测试显示了小三星能做什么。

紧凑型Android 平板电脑很实用,也很方便,但少之又少。因此,我们在评测数据库中只找到了8.7英寸的三星Galaxy Tab A7 Lite的少数几款对比设备。

三星的Galaxy Tab A7 Lite的起价为169欧元(约199美元),采用联发科的Helio P22T MT8768T SoC,在性能方面属于入门级别的产品。尽管如此,八核CPU的计算能力应该也足够用于观看Netflix和游戏环节。这款小型平板电脑还拥有支持杜比全景声的立体声扬声器,5100毫安时的电池容量足以持续到系列赛的最后一刻。

对于它的8.7英寸显示屏,Galaxy Tab A7 Lite依赖于一个分辨率为1340 x 800像素的TFT面板,这相当于一个5:3的长宽比。

机箱 -Galaxy Tab A7 Lite,高质量的机箱

三星提供的迷你平板电脑有 "深灰色 "和 "银色 "两种颜色。这些颜色指的是后盖的颜色。我们测试的 "深灰色 "版本的显示屏边框是黑色的,而 "银色 "版本则是白色的。

屏幕的边缘在两个短边上相对较宽,那里还有一个杜比全景声扬声器,这就是为什么81%的显示与表面比率相当低。由于其紧凑的尺寸,Galaxy Tab A7 Lite很适合拿在手里,但它相当重,有366克(约12.9盎司)。

尽管价格很低,但制造质量很好,因为三星的平板电脑以高质量的外观取胜。由于其稳定的框架,它只能被压抑或扭曲得很小。塑料按键只有极小的发挥,并且有一个令人愉快的坚定的压力点。

特点 - 三星平板电脑的3GB内存和32GB存储空间

三星的Galaxy Tab A7 Lite配备了3GB的内存和32GB的内部存储。它可以通过microSD卡进行扩展,其大小可以达到1TB。我们测试的Wi-Fi版本在三星商店的价格为169欧元(约合人民币199元),而199欧元(约合人民币235元)的LTE版本则是到期的。

这款平板电脑的其他功能包括一个支持OTG的USB 2.0端口,以及分布在短边上的两个支持Dolby Atmos的扬声器。还包括一个3.5毫米插孔,但没有天线或用于连接耳机的无线电功能。作为回报,三星支持DRM Widevine L1,可以播放高清质量的流媒体。

微型SD卡读卡器

用东芝的Exceria Pro M501作为参考存储卡,Galaxy Tab A7 Lite的microSD性能很稳定。复制速度很高,即使是昂贵的平板电脑也无法在连续读取方面做得更好。Galaxy Tab A7 Lite只是在顺序写入方面有点慢。

软件 -Android 11和儿童模式

三星为其小型平板电脑配备了Android 11和内部用户界面OneUI 3.1。在8月初测试时,Android 安全补丁是在5月1日更新的,所以它们已经不完全是最新的了。

与标准的Android ,OneUI只做了一些改变,并以清晰的布局包括一个应用抽屉来得分。除了谷歌和三星的应用程序外,只有少数第三方应用程序被预装:Netflix、Spotify和微软的Office、OneDrive和Outlook。除了Netflix和OneDrive,所有第三方应用都可以卸载。

一个特殊的功能是三星儿童模式。它可以通过访问栏方便地激活,为年轻人提供一个安全的媒体和游戏环境。

这款平板电脑的32GB存储空间中只有不到19GB是免费的。micro-SD卡可以作为媒体数据的标准存储空间,如照片。然而,在测试中,我们无法在上面存储应用程序数据。

通信和GNSS - 快速和稳定的WiFi 5

Galaxy Tab A7 Lite的WiFi版本在WLAN中以WiFi 5的速度进行通信,还支持蓝牙5.0,但不支持NFC。

通过我们的参考路由器Netgear Nighthawk AX12,三星平板电脑实现了良好的传输速率,在发送和接收方向都非常稳定。Galaxy Tab A7 Lite的最高传输速率为342 MBit/s,在对比设备中排名相当靠前,甚至可以超过更昂贵的 Apple iPad Mini 5.

由于其方便的格式,Galaxy Tab A7 Lite很适合移动使用。这也得到了该平板电脑通过GPS(L1,L5)、GLONASS(L1)、BeiDou(B1,B2a)和Galileo(E1,E5a)精确定位的支持。三星可以在室内对我们进行定位,精确度可达2米(约6.6英尺),在室外甚至在1米(约3.3英尺)之内--这都是非常好的结果。

在道路上的精确度也保持很高。三星的Galaxy Tab A7 Lite记录了我们10公里(约6.2英里)的自行车骑行,几乎和Garmin Edge 500专业导航设备一样精确。

照相机 - 仅适用于快照

用主相机拍摄
用主相机拍摄

三星只提供了关于Galaxy Tab A7 Lite的摄像头的极少细节,当然是因为它们不是该平板电脑的旗舰产品。自拍相机的分辨率为200万像素,主摄像头为800万像素。两者都能以每秒30帧的速度录制最大为1920 x 1080像素的视频。

你不一定期望一个廉价的平板电脑有好的照片和视频质量。不幸的是,Galaxy Tab A7 Lite也不例外。用自拍相机拍摄的照片模糊不清,有噪音,缺乏对比度。

主摄像头提供了更好的图片质量,在良好的照明条件下拍摄的照片相对清晰。然而,照片显示的细节很少,这在变焦拍摄中特别明显,一般在黑暗的图片区域。它们往往曝光过度或曝光不足,并且由于色彩平淡而几乎缺乏任何动态。在弱光条件下,相机最终投降,只能捕捉到模糊的轮廓。

我们再看一下主摄像头在受控光线条件下的表现。在最佳亮度下(上色图),除了深灰色调外,平板电脑相当准确地再现了原始色彩,并相对清晰地呈现了测试图。然而,在最低亮度下(较低的颜色图),所有的准确性都消失了,测试图只能模糊地看到。

配件和保修 - 三星平板电脑与7.8瓦的电源适配器

三星包括一个7.8瓦的电源适配器(5V/1.55A),一条USB线(A型到C型),一个SIM卡工具,一个快速入门指南,以及一个带有保修信息的小册子,与Galaxy Tab A7 Lite一起。三星不为其平板电脑提供任何特殊配件。

三星Galaxy Tab A7 Lite的保修期为24个月。

输入设备和操作 -Galaxy Tab A7 Lite带有面部识别功能

三星的Galaxy Tab A7 Lite的电容式触摸屏对手指的阻力小得令人愉快,并对输入的内容作出精确的反应,直至角落。然而,响应速度可以时不时地快一点。对内存和性能要求较高的应用程序,如PUBG Mobile,给平板电脑带来了明显的压力--在游戏中一切都能顺利运行,但在Android 界面和游戏之间的切换却有点迟缓。

这款平板电脑没有指纹传感器,但它通过面部扫描提供生物识别认证。只要环境足够明亮,二维解锁的效果相当可靠,但速度不是很快。

Galaxy Tab A7 Lite的TFT屏幕为8.7英寸,分辨率为1340 x 800像素。这导致179PPI的像素密度相当低,这在日常使用中部分是明显的。例如,在5:3的屏幕上,小字体不是太清晰。

在白色背景下,TFT显示屏的平均亮度为332.1cd/m²,但不能实现非常均匀的照明(85%)。在均匀分布的明亮和黑暗图像区域,亮度增加到360 cd/m²(APL50)。在有源环境光传感器的作用下,最大可达到355cd/m²。在最低的亮度设置下,屏幕仍然以13.12 cd/m²的亮度闪耀。很好。Galaxy Tab A7 Lite不使用PWM来控制显示亮度。

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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 15315 (minimum: 5 - maximum: 2500000) Hz was measured.

除了亮度之外,你无法在三星平板电脑上调整任何图片参数,所以你必须接受你得到的东西。而这充其量是平均水平。由于0.24cd/m²的低黑值,Galaxy Tab A7显示的内容具有很高的对比度(1500:1),但由于8744K的色温太高,这只发生在一个明显的蓝色偏移。由于delta E值为6.7(颜色)和7.6(灰度),该显示器也不是特别真实的颜色。

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
27.6 ms ... rise ↗ and fall ↘ combined↗ 14.4 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.9 ms).
       Response Time 50% Grey to 80% Grey
52.8 ms ... rise ↗ and fall ↘ combined↗ 26 ms rise
↘ 26.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 86 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (37.8 ms).

由于其最大亮度为360cd/m²,Galaxy Tab A7 Lite在户外使用时很快达到了极限。在阳光直射下很难阅读内容。长此以往,眼睛在阴凉处也会感到紧张。

视角照片没有太好地反映出来,但三星平板电脑的TFT面板在视角上并不太稳定。当你从一个小角度看显示器时,它已经变暗很多了。然而,屏幕不会进一步变暗,即使从极端的侧面看也仍然清晰可辨。

性能 - 入门级的联发科MT8768T系统芯片

三星的Galaxy Tab A7 Lite采用了联发科的Helio P22T(MT8768T)。这款八核SoC属于入门级性能类别,由8个ARM Cortex-A53内核组成。它们分布在两个各有4个核心的集群中,时钟频率分别高达2.3和1.8GHz。MT8768T的图形芯片是 PowerVR GE8320.

采用联发科SoC,Galaxy Tab A7 Lite的系统性能其实并不突出。总的来说,处理起来很迟钝,因为总是有小的延迟,例如在许多打开的应用程序之间切换时,平板电脑在任何时候都不能快速反应。

在性能方面,联发科MT8768T仅仅领先于其对应的华为MatePad T8。 华为MatePad T8的性能。 MT8768.两者都紧随其后的是 亚马逊Fire HD 8 Plus 2020,它配备的是 MT8168一个稍弱的联发科SoC。高通 高通骁龙429三星Galaxy Tab A 8.0 (2019)不能完全跟上联发科的三人组。

Galaxy Tab A7 Lite并没有提供特别突出的读写速度,这是因为它的eMMC闪存相当迟钝。然而,竞争对手也没有提供更高的速度。

游戏--性能良好,图形细节减少

作为一款紧凑的游戏平板电脑,Galaxy Tab A7 Lite的表现相当出色。它支持杜比全景声的扬声器提供了坚实的立体声,而且它对输入的反应相当快。然而,你不能指望目前的游戏能在全细节下顺利运行。

其中一个例子是PUBG Mobile,它不允许比 "平衡"/"中等 "更好的图形设置,然后仍然由平板电脑显示,平均每秒不超过25帧。然而,你仍然可以用它来玩好这个射击游戏。在图形要求不高的游戏中,更高的帧率也是可能的。Asphalt 8(Google Play不提供Asphalt 9在三星上的下载)和Armajet 都以每秒30帧运行。

我们用工具Gamebench来确定帧率.

排放 - 凉爽的三星平板电脑

温度

三星平板电脑在操作过程中几乎没有发热。我们在主摄像头周围的 "热点 "处测量了37°C(98.6°F),这几乎不超过人体温度。因此,Galaxy Tab A7 Lite拿在手里时总是感觉很舒服。

联发科的SoC也确保了平板电脑内部温度适中。Wild Life基准测试不受支持,所以我们不能对Wild Life压力测试的稳定性做出说明。然而,GFXBench的T-Rex和曼哈顿压力测试方案运行平稳。它们表明,即使在运行这两个基准测试30次后,该平板电脑也不必对其性能进行节流,因此它的内部永远不会太热。

演讲者

Galaxy Tab A7 Lite的立体声扬声器支持杜比全景声(Dolby Atmos),并产生一个良好的声音,具有线性的中音和非常线性的高音。然而,尽管有著名的名字,但几乎听不到低音,这就是为什么扬声器听起来有点薄。

耳机和外部扬声器可以通过3.5毫米插孔或蓝牙5.0连接到平板电脑。一个小缺点。音频插孔的信噪比为58.09dBFS,不是特别好。

电源管理--三星平板电脑具有良好的电池运行时间

消耗功率

Galaxy Tab A7 Lite在功耗方面并不突出,因为它既不消耗大量电力,也不消耗很少的电力。因此,它加入了其他Android 平板电脑的行列,与三星一样,在空闲状态下只需要不到3瓦,在负载状态下平均需要约4瓦。

5100毫安时的电池通过附带的7.8瓦特电源进行充电。在测试中,完全将电池从0充电到100%需要整整4个小时。
