外壳 - Pixel 7a使用回收的铝材
谷歌Pixel 7a的设计借鉴了其前代产品,即Pixel 6a- 但它现在有海(浅蓝色)、炭(黑色)、雪(白色)和珊瑚色。后者是我们测试设备的颜色。它的显示屏与表面积之比为81%,还算不错--不过,它的边框肯定比两款更昂贵的机型要厚。即便如此,Pixel 7a还是一款相对紧凑的智能手机。
谷歌智能手机的背面现在是由3D热成型塑料制成的,看起来和感觉都与玻璃相似。只有当你仔细比较时,你才会发现这种材料更沉闷一些。正面由康宁大猩猩3号玻璃保护,外壳中使用的铝是100%回收的。
这款手机的构造很好。如果你试图扭动它,它只会发出一点吱吱声,而且设备上没有明显的缝隙。只有外壳的背面在相机模块的顶部和框架之间有一个稍大的缝隙。SIM卡槽与边框几乎无缝连接,盖子的颜色与外壳的其他部分只有细微差别。
Pixel 7a的电池被牢牢地集成在外壳中,无法自行调换。这款智能手机通过了IP67认证--这意味着它可以防尘,并能防止偶尔浸泡在淡水中。
连接性--谷歌的智能手机有一个瘦身的USB接口
规格表显示,谷歌Pixel 7a有一个USB 3.2 Gen.2连接,这意味着它应该支持高达10GBit/s的传输速率。然而,在我们的复制测试中,我们只测得228.27MB/s,与较慢的USB 3.2(Gen.1)端口处于同一水平。相比之下:ROG Phone 7的ROG Phone 7管理的速率几乎达到860 MB/s。虽然支持OTG,但手机既不支持NTFS也不支持exFAT的外部存储媒体。使用这个USB端口,有线图像输出也同样困难。
除此以外,Pixel 7a仍然只具备最基本的功能,包括蓝牙5.3和NFC。
软件--Android 手机的长期更新供应
谷歌Pixel 7a安装了Android 13,并且只使用谷歌自己的应用程序。许多功能将已经从 Pixel 7.安全补丁将按月推出,总共五年。此外,Pixel 7a将收到三个大的系统更新,这意味着它仍将看到Android 16。
通信和GNSS - Pixel 7a已经掌握了6-GHz WLAN
谷歌Pixel 7a支持广泛的移动频段以及所有常用标准,包括5G Sub6。在较大的城市,其接收效果应该不错。
由于支持Wi-Fi 6E,这款手机可以利用2.4、5.0和6.0 GHz的WLAN连接。特别是它支持相对年轻的6GHz网络,这在这个价格范围内的许多手机中是找不到的--通常,只有高端智能手机才能做到这一点。然而,Pixel 7 和Pixel 7 Pro 仍然比7a有优势,因为它们在这个频率区域的运行速度几乎是7a的两倍。

Pixel 7a可能只支持单频GNSS,但它支持所有著名的卫星网络:GPS、Glonass、Galileo、BeiDou和QZSS。卫星定位在建筑物内的速度甚至相当快,尽管有技术限制,但谷歌手机在建筑物外仍能保持良好的信号。
在一次自行车旅行中,我们将Pixel 7a与Garmin Venu 2进行了比较。令人惊讶的是,在追踪我们的行程时,智能手机显示出一些弱点,而且经常有点偏离方向。在一天结束时,这应该仍然被证明足以满足日常导航的需要。
通话功能和通话质量
谷歌Pixel 7a支持VoLTE和WLAN通话等基本功能--此外,它还支持一项名为 "清晰通话 "的功能,据称即使在嘈杂的环境中也能可靠地过滤掉背景噪音。
事实上,Pixel 7a在实践中确实提供了良好的通话质量,它能够过滤掉相当多的背景噪音--即使在繁忙的街道上。这款手机的扬声器模式确实听起来不错,但它的麦克风没有最广泛的覆盖范围。
这款智能手机有一个Nano SIM卡的空间,你还可以另外(或替代)设置一个eSIM卡。
相机--Pixel 7a的主摄像头性能稳定
Pixel 7a的前置摄像头已升级为1300万像素--然而,由于光圈为f/2.2,它在名义上的感光度低于像素6a.你可以使用这个镜头以60 FPS的速度录制全高清视频,或以30 FPS的速度录制超高清视频。由于相机的均匀照明,自拍看起来很好,人像模式提供了漂亮的虚化水平,可以清楚地识别主体和背景。
6400万像素的主摄像头--具有光学图像稳定功能(OIS)--也能拍出好照片。不幸的是,它们的颜色色调与Pixel 7 Pro ,略有不同,但在低光照条件下,差异仍然小得令人惊讶。这款手机只具有数字变焦功能,能够放大8倍,但不幸的是,质量从2倍变焦的标志开始恶化。它的超广角镜头也有一点不足之处:图像的边缘往往有点模糊,扭曲和颗粒变得相当明显。
使用主摄像头,可以用高达60FPS的超高清录制视频,在实践中,它们看起来相当不错。虽然,你只能在30和60FPS之间选择,24FPS甚至不是一个选项。

我们的测试图被描绘得很好--只有角落有点模糊。唯一令人失望的是,谷歌甚至没有为用户提供64MPix模式--相反,每张照片都使用了像素分选技术,以实现16.1MPix的总量。可选的RAW数据也是如此。
附件和保修 - 缩小的交货范围
在美国,购买Pixel 7a的人可以享受一年的标准保修,不能延长。它的交货范围仍然是相当小的。这只包括一条USB-C电缆、一个OTG适配器以及一个SIM卡工具。
7a的可选配件包括一系列不同颜色的塑料外壳,一个皮套,一个透明外壳,一个配套的30瓦电源和Pixel Stand 2。
输入设备和操作 - Pixel 7a具有良好的振动电机
谷歌Pixel 7a拥有漂亮光滑的俘虏式触摸屏,由康宁大猩猩3号玻璃保护。
生物识别安全由位于屏幕内的光学指纹传感器负责,该传感器工作可靠,可立即解锁手机。现在,你也可以通过手机的摄像头切换到使用面部识别,然而,这个选项的安全性要差一些。
该设备还掌握了众所周知的功能,如现在播放、单手模式和有限的永远在线显示屏,它可以为你提供时间和日期以及天气信息。指纹传感器的定位也可以用AoD来突出,但这要消耗更多的能量。
它的线性振动马达(Z轴)可以提供坚实而精确的反馈。
显示屏 - 谷歌手机有一个明亮的90Hz OLED屏幕
Pixel 7a的显示屏尺寸为6.1英寸,分辨率为2,400 x 1,080像素。最后,谷歌为他们的中端设备提供了更高的刷新率:90赫兹。虽然,这首先必须在设备的设置中激活(平滑显示)。该手机还支持HLG、HDR10和HDR10+的HDR标准。
在屏幕亮度方面,7a甚至成功地超过了像素7(947 cd/m²)--通过激活环境光传感器,这款手机在描绘纯白色屏幕时,平均达到了1,010 cd/m²。在光线和黑暗区域均匀分布的情况下(APL18),这款手机实现了高达1383 cd/m²的数值。如果你愿意手动设置亮度,那么你可以获得486 cd/m²。
Pixel 7a的OLED闪烁相当明显--在最低亮度水平下,手机在不安分的177和364赫兹之间波动,这意味着对光敏感的用户在使用这款手机时很可能有一些问题。

Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 218 Hz | ||
The display backlight flickers at 218 Hz (worst case, e.g., utilizing PWM) . The frequency of 218 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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. |

手机的色彩描述和白平衡使用 "自然 "设置进行了最佳调整,并且没有显示出批评的理由--颜色没有显示出明显的异常值。使用 "自适应 "模式,白平衡仍然相似,但颜色更饱和一些。

在户外,Pixel 7a提供了良好的可读性--即使在阳光下。只是其光亮的表面偶尔会让人觉得有点烦。
环境光传感器的工作非常可靠,可以快速调整亮度。
OLED面板的视角稳定性非常好--正如预期。在非常平坦的视角下,反射变得最令人讨厌。然后,内容被描绘得稍微冷一些,亮度也略有下降。
性能 - Pixel 7a有一个Tensor G2
Pixel 7a使用谷歌2022年的顶级SoC,即Tensor G2。Tensor G2,并拥有8GB LPDDR5内存。
这款手机的性能与其他使用这种SoC的Pixel智能手机相似。然而,在高负载情况下,Pixel 7a与它的大哥哥们相比有一点差距--大概是由于SoC的冷却效率较低。
由于该设备的90-Hz显示屏,系统速度很好,很流畅。

游戏--尽管是顶级的SoC,但不是最流畅的
在这个阶段,我们很遗憾无法展示我们通常所做的FPS记录,因为每次我们试图这样做时,Pixel 7a都会大幅升温并崩溃。
即便如此,我们还是想尝试描述一下我们的印象。休闲游戏对谷歌智能手机来说没有问题,而更复杂的游戏,如《PUBG》或《源氏冲击》则不那么容易运行。虽然射击游戏《PUBG》在最高的图形设置(超高清)下只是有点生硬,但手机在《源氏冲击》上的挣扎要大得多。我们建议将帧率限制在30FPS,因为如果不这样做,游戏在战斗中会开始滞后。
除此之外,Pixel 7a在横向模式下运行游戏方面做得很好--但有时,你的手会遮住环境光传感器,屏幕突然变得很暗。
排放--冷却效果弱,仍然很热
温度
在闲置模式下,谷歌Pixel 7a的表面温度仍然不明显,但在负载下,它们开始上升了不少。虽然,必须指出的是,我们已经开始改用密集型的Burnout基准测试来模拟高负荷,这意味着这些数值只能部分地进行比较。但是,仍然可以在日常使用中达到这些温度。这是很温暖的,但没有什么太出格的地方。
在3DMark压力测试中,有一件事变得很明显,我们在基准测试中已经开始看到:Pixel 7a的SoC存在散热不良的问题,这意味着其长期性能比更昂贵的机型差很多。

发言人
谷歌Pixel 7a上的两个扬声器听起来相当体面。当然,低音和精确的高音有所欠缺,但我们观察到的性能对于智能手机来说是不错的。
有线耳机可以通过USB-C端口连接。蓝牙5.3是无线的,在音频编解码器支持方面有一些积极的惊喜。除了常见的编解码器SBC、AAC、aptX、aptX HD和LDAC,还支持LC3和Opus。

电池寿命 - 非常好,但不太符合预期
消耗功率
谷歌Pixel 7a的功耗在激活90赫兹时已经很低了。只是在负载下变得更高--可能是由于更耗电的Burnout基准测试。
Pixel 7a支持高达18瓦的快速充电,尽管 "快速 "是相对的,因为在我们的测试中,谷歌智能手机需要两个多小时才能充满电。20分钟后达到25%的标准,49分钟后达到50%的标准,84分钟后达到80%的标准,94分钟后达到90%的标准。
一个新特点是,Pixel 7a现在还支持无线充电。

运行时间
这款手机的电池容量为4385毫安时,比Pixel 6a的电池容量略小,但在我们调整了显示亮度(150cd/m²)的实际WLAN测试中,其运行时间更好。不幸的是,在其他测试中,情况就不一样了。谷歌肯定会在某个时候对此进行改进,因为我们的功耗测量表明,还有很多未使用的潜力。
然而,Pixel 7a在目前的状态下已经取得了非常好的成绩。

Pros
Cons
判决 - 内部竞争
Pixel 7a的竞争对手有很多地方需要改进,因为这款谷歌智能手机已经做得很好。它采用了明亮的OLED屏幕,色彩还原准确--而且终于有了90Hz的刷新率。这款手机的主摄像头能拍出很好的照片,它的电池运行时间也很好--尽管它们确实有一点进一步改进的余地。其功能由IP67认证、无线充电和长时间的更新供应完成。
谷歌Pixel 7a是一款强大的中端智能手机,在更高的价格范围内,它的朋友和敌人都在竞争。
但即使是Pixel 7a也不能完全逃避批评:在其规格表上,谷歌将手机的USB端口命名为3.2 Gen.2,然而,它缺少一个有线图像输出选项,其传输速率更多是在较慢的USB 3.2(Gen.1)连接范围内。此外,它的OLED闪烁相当明显,而且该手机没有利用任何调光技术来缓解这种情况。如果你期待Pixel 7a的快速SoC,你确实必须考虑到由于手机的冷却性能较弱而带来的轻微限制。它的定位性能也留有改进的余地。
在发布会上,像素7被证明是一个很好的选择--小米13 Lite小米13 Lite和Galaxy A54都有一些Pixel 7a所缺乏的优势。
