三星Galaxy Tab A7 LTE 2022平板电脑评测--更新后的电池寿命得到改善

我将会回来。

三年前,三星Galaxy Tab A7是我们最好的经济型平板电脑之一。现在,这家韩国制造商给市场带来了一个带有新的SoC的更新版本。在我们的测试中,看看有什么变化,以及这款10.4英寸的平板电脑是否仍然值得购买。

三星Galaxy Tab A7 2022

那些为家庭或学校寻找实惠的平板电脑的人,很难绕过三星Galaxy Tab A7。有一段时间,这款平板电脑的竞争对手寥寥无几,但最近又有更多来自其他制造商的、同样价格低廉的替代品开始出现。

因此,三星用目前的SoC改善了它的销售业绩,并以现代软件重新推向市场。 LTE版本的价格仍然是近200欧元(约合221美元),而对那些WiFi足够的人来说,只需支付50欧元(约合55美元)。

我们在测试中更详细地了解了新的(但实际上已经是三年前的)平板电脑是否仍能满足日常任务的需要,或者寻找一个更现代的替代品是否更有意义。

案例--明显的边缘

三星保持了与前代产品完全相同的金属外壳。但这是完全可以的:边框有一个合适的尺寸,使平板电脑看起来与时俱进,同时还能让你舒适地握住平板电脑,而不会意外地触发触摸屏。

在这一点上,市场上有一些更轻的10英寸平板电脑,但那些不会带来持续时间那么长的电池,而三星Galaxy Tab A7 2022的重量为477克(约1.05磅),拿在手里感觉很舒服。

显示屏和边框之间的材料过渡原来有点粗糙,你可以明显感觉到边缘,这稍微降低了对平板电脑质量的印象。但除此之外,Galaxy Tab显示出良好的做工,提供了稳定的结构。它只能最小限度地翘起,而且不会吱吱作响。

那些喜欢银色或金色版本的 A7 2020会感到失望,因为这款平板电脑的新版本只有深灰色和黑色显示屏边框。

设备 - 储存量少

三星Galaxy Tab A7 2022有3GB内存和32GB存储空间,无论你是选择LTE版本(SM-T509)还是WiFi版本(SM-T503)。尽管采用了更先进的SoC,但在其他方面的设备并没有什么变化。继续有蓝牙5.0和一个USB-C端口,通过USB-2.0标准进行内部连接。

我们应该在这里提到,大多数竞争对手在这一点上为客户提供更多的存储空间。然而,如果你无论如何只在大部分时间上网,只使用很少的应用程序,那么存储空间是足够的。

微型SD卡读卡器

该读卡器支持存储量高达1TB的microSD卡。移动应用程序到卡上仍然不被支持,只允许你使用卡来存储媒体数据。

在使用我们的Angelbird V60参考卡的测试中,Galaxy Tab A7 2022的microSD读卡器表现出一流的水平,但无法充分利用快速存储卡的潜力。

软件 --Android 12板载

仅仅是软件的更新就使得Tab A7的更新有了很大的进步:首先,你得到一个相对当前的Android 12的交付状态。然后,这被三星的OneUI 4.1所覆盖,它对操作系统提供了一些广泛的调整。

虽然三星预装了几个第三方应用程序,但大部分都可以卸载,没有任何问题。Widevine L1认证允许你以全高清分辨率播放大型流媒体服务的流媒体。

在本次测试时,安全补丁是2022年7月的,这使得它们无望过时。你最多只能指望一些零星的额外补丁。制造商没有说任何关于可能更新到Android 13。

通信和全球导航卫星系统 - 移动接收不强

随着三星Galaxy Tab A7的更新,你可以选择纯WiFi或LTE版本。我们测试的是三星Galaxy Tab A7 SM-T509,它也可以使用4G网来上网。它还支持电话。

移动通信调制解调器的频率覆盖范围没有变化,欧洲所有重要的4G频段都继续得到支持。在前往其他一些大洲时,将Galaxy Tab A7作为移动互联网设备使用应该也是可能的,但在全球使用时缺少几个频段。

在我们的随机定点测试中,移动接收效果相当平庸,无法与高端智能手机相比。

WiFi 5又被包括在内。在与我们的华硕ROG Rapture AXE11000参考路由器的测试中,Galaxy Tab A7 2022在接收数据时显示出一些良好的速度,但在发送数据时却落在竞争对手后面。

在户外,需要相当长的时间才能让定位模块可靠地确定我们的位置,即使如此,它也只能达到8米(约26英尺)的大致精度。Galaxy Tab A7 2022并不与特别多的卫星通信。

我们的实际测试是为了显示该平板电脑在用于日常导航时的表现。为了测试这一点,我们跳上我们的自行车,还带着Garmin Venu 2智能手表进行比较。

虽然结果很难说服那些重视高精度的用户,但它仍然足以大致追踪我们的路线。平板电脑经常通过房屋区块走一些捷径,而不是按照实际走的路线,或者它确定的位置在实际路线旁边。

照相机 - 为一些图像伪影做准备

用前置摄像头拍摄的照片
用前置摄像头拍摄的照片

三星Galaxy Tab A7 2022的相机设备也依赖于前代产品的技术。背面同样有一个800万像素的摄像头,即使在良好的光线条件下,它在提供可用的照片方面也有一些明显的问题。尽管图像内容是可识别的,但它们看起来被洗掉了,而且有颗粒感。

在弱光条件下,一些图像伪影出现在黑暗区域,图像清晰度也进一步下降。虽然你可以用这台平板电脑拍快照或记录情况,但你不应该期待任何漂亮的照片。

主摄像头至少能够录制可用的视频吗?好吧,如果你不考虑抽风的自动对焦和略微冲淡的颜色,视频是可用的,特别是快速的亮度调整是令人信服的。

在平板电脑前面还有一个500万像素的摄像头。它创造的自拍是可用的,只要你不试图把它们放大太多。

主摄像头即使在全棚照明下也会产生一些图像伪影,形成相当暗淡的照片。在1勒克斯的照明下,至少你仍然可以识别图像内容的轮廓。

配件和保修 - 一个很好的选择

三星Galaxy Tab A7 2022的包装盒包括一个充电器、USB线和一个SIM卡工具。

随着该设备的高度普及,尽管其购买价格可以承受,但三星也提供了一些配件,如键盘盖,目前也相当实惠,约45欧元(约50美元)。你还可以得到一个包括设备支架的背面保护罩。此外,第三方供应商也为该平板电脑提供了许多盖子。

只要是在欧盟购买的设备,三星为其设备提供24个月的制造商保修。

输入设备和操作 - 可进行人脸识别

尽管制造商安装了自己的键盘应用程序,但你也可以用其他应用程序替换它,不会有任何问题。60Hz的触摸屏反应相当灵敏。在这个价格级别,更快的显示屏还不是标准。

没有指纹传感器,但你可以使用面部识别来解锁平板电脑。只要你按下待机键,人脸就会被识别,稍有延迟,平板电脑也可以选择打开上次使用的显示屏幕。人脸识别在黑暗中工作也没有任何问题,只需利用显示屏的光线。

然而,这里使用的人脸识别技术是一种软件解决方案,使得它在防止操纵方面不那么安全。

子像素网格

Galaxy Tab A7 2022配备了一个IPS显示屏,提供2000 x 1200像素的典型分辨率。与前代产品相比,显示屏的亮度略有下降,但现在的亮度分布更加均匀。

不幸的是,黑值同时也增加了,导致对比度下降,屏幕显示的图像相当暗淡。

至少,Galaxy Tab的屏幕继续避免使用PWM。

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 8705 (minimum: 5 - maximum: 343500) Hz was measured.

我们用光谱光度计和CalMAN软件的测量结果显示,显示器中存在明显的蓝色色调。此外,颜色的再现相当不准确,也就是说,太冷了。三星没有为白平衡提供任何调整选项。

响应时间也相当慢,这对游戏玩家来说应该是特别烦人的。

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

In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 89 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (20.9 ms).

由于显示屏亮度不足,这款平板电脑在户外几乎无法使用,而且显示屏上的反光实在太强。

另一方面,可视角度创造了良好的印象,即使从非常陡峭的视角看,图像内容在显示屏上仍然很容易识别。

性能--经济实惠的平板电脑有很大的能量

Galaxy Tab A7的2022年版本的最大变化可能是SoC。三星改用Unisoc,这是一家中国制造商,其SoC在过去几年中被用于许多廉价的智能手机和平板电脑。

Unisoc T618带来了两个性能和六个效率核心,每个核心的时钟速度高达2GHz。在与前代产品的直接比较中,性能差异很明显,但不是很剧烈,最多只有15%。Galaxy Tab A7 2022很容易就能跟上这个价格级别的其他平板电脑。

在日常操作中,Tab A7在滚动浏览菜单时运行平稳。然而,在要求较高的应用程序中,经常会出现停顿,而且可用的性能储备不是特别多。

蹩脚的eMMC闪存无法激发任何真正的热情,因为它延迟了数据传输和加载时间。Galaxy Tab A7 2022在这里显示自己特别慢。但是,由于这个价格级别的其他平板电脑没有提供快得多的存储,你可能只是在这一点上不能期望更多。

游戏--《暗黑破坏神》中的图形错误

使用这款平板电脑进行游戏,几乎没有任何乐趣。首先,在《PUBG移动版》和《暗黑破坏神:不朽》中用GameBench测定的帧率是平庸的,在高设置下甚至没有稳定的30帧。其次,在《PUBG移动版》中,即使是低设置,也只能获得38帧,而且间歇性地出现一些明显的下降。

此外,在《暗黑破坏神:不朽》中还会出现一些高额的图像伪影。尽管你可能会猜到你的游戏角色和敌人的位置,但这样的游戏其实并没有任何乐趣。

在我们的测试中,通过触摸屏进行控制,如果有必要,也可以通过位置传感器进行控制,没有任何问题。

温度

这样一个10英寸的平板电脑提供了一个相对较大的内部空间,使SoC很容易被冷却。这在Galaxy Tab A7 2022中也很明显,它在温度发展方面没有任何问题。即使在长时间满负荷工作的情况下,该设备也只升温到难以察觉的33.8℃(92.8°F)。

在用3DMark进行的压力测试中,我们也可以看到,在较长时间的运行中,性能并没有受到影响。

这款经济实惠的平板电脑带来了四个扬声器,在这个价格级别上几乎没有任何制造商能够提供。这也使得它能够实现柔和的立体声效果,即使扬声器之间的距离当然相对较小。

声音是强大的。虽然它在全音量时略微强调了高音,但总体来说还是相当不错的。声音可以听得很清楚,音乐听起来也很干净。

然而,HiFi爱好者仍会喜欢使用耳机或外部扬声器,可以通过3.5毫米音频端口或蓝牙5.0连接。支持的无线蓝牙编解码器的选择是相当少的。有SBC、AAC、aptX、LDAC和三星自己的SSC,支持最必要的编解码器,但不超过这些。

电源管理--Galaxy Tab A7的高效运行

消耗功率

与上一代产品相比,三星Galaxy Tab A7 2022的效率明显提高,也明显超过了这个价格级别的其他平板电脑。特别是在没有任何负载的情况下,其耗电量非常低。

使用7.8瓦的充电器,需要长达4:30小时,直到大电池完全充电。这一点特别令人恼火,因为这款平板电脑还可以用高达15瓦的功率充电,但三星只提供了一个太弱的充电器。

电池寿命

我们的测试装置能够很好地利用其效率,也实现了良好的电池寿命:在我们的WLAN测试中,强大的7,040毫安时电池可持续14:34小时。

负载下的电池寿命也是令人信服的:在不得不再次充电之前,你可以玩长达4:10小时的游戏。

有趣的是,前代产品在空闲状态下的电池寿命甚至更长,所以我们目前的模型仍然有一些优化的需要。 但考虑到罕见的更新,你在这方面不应该有太多的希望。

结论 - 光和影在Galaxy Tab A7 2022

测试三星Galaxy Tab A7 LTE 2022。
测试三星Galaxy Tab A7 LTE 2022。

三星Galaxy Tab A7 2022提供了一些特殊的功能,使其成为经济型平板电脑中的一个好选择。例如,它的四个扬声器能产生令人信服的声音。此外,这款平板电脑在负载情况下几乎不发热,为其价格等级带来了良好的性能值,运行效率高,而且电池可以持续很长时间。

另一方面,也有一些地方不太令人信服。首先是相机,即使对平板电脑来说,它的照片质量也非常有限,包括一些图像伪影。屏幕也非常暗,色彩再现有一种冷色调。此外,存储设备也不是最新的了。

因此,这取决于你想用Galaxy Tab A7 2022,以及什么对你来说是重要的。那些正在寻找一个坚实的伴侣,特别是在室内,以及那些只安装很少的应用程序和不关心相机的人,将以很少的钱得到一个坚实的平板。

三星Galaxy Tab A7 2022是一款经典产品的温和更新,电池寿命良好。然而,你不应该太在意好的相机或明亮的屏幕。

在这一点上,你可以从竞争对手那里得到更多的存储空间,比如说 realme Pad,它也能从四个扬声器产生声音,或 联想Tab M10 2022或者联想Tab M10 2022,它能够以良好的无线网络接收来说服我们。

价格和可用性

带有Unisoc处理器的三星Galaxy Tab A7的2022年更新版似乎在美国、英国或印度无法买到。在美国,只有非常相似的Galaxy Tab A8配备了Unisoc处理器,例如在亚马逊从179美元起售。
