您很可能听说过Energizer。是卖电池的吧？没错(True)，但它也已成为智能手机品牌。获得该品牌名称使用权的法国公司(brand name)Avenir Telecom早在 2015 年就开始以(Avenir Telecom)Energizer的名义销售手机。今年，他们发布了新的智能手机和功能手机产品组合。将它们结合在一起的共同主题（除了它们的品牌名称(brand name)）是电池及其提供的自主权。在这篇评论中，我们评估了Energizer Power Max P550S ，这是一款拥有 5.000 mAh 电池(mAh battery)的低成本Android 智能手机(Android smartphone)- 按照今天的标准，相当大。让我们深入研究：
Energizer Power Max P550S：它对谁有好处？
Energizer Power Max P550S是一款出色的智能手机，适用于：
- 需要具有库存Android 操作系统(Android operating)的坚固手机的用户
- 希望通过智能手机延长电池寿命的人(battery life)
- 预算有限的买家
优点和缺点
我们喜欢以下关于Energizer Power Max P550S的内容：
- 惊人的电池寿命
- 坚固的设计，全金属机身
- 没有安装不必要的应用程序
- 它有一个原封不动的Android(Android operating)操作系统
但是，也有一些负面因素需要考虑：
- 智能手机很重
- 屏幕色彩还原(color reproduction)不如其他同价位智能手机
- 随附的耳机质量差
判决
Energizer Power Max P550S是一款简单易用的智能手机，适合低预算购买者。虽然手机很重，但其出色的电池寿命(battery life)可能对某些用户来说是决定性的品质。相机平庸，手机坚固但就设计而言并不引人注目，虽然我们通常喜欢干净的Android 操作系统(Android operating)，但使用Energizer Power Max P550S的体验让我们相信，有时候，少就是……少。这款智能手机非常适合那些想要便宜的智能手机、电池寿命(battery life)长、干净的Android 发行版(Android distribution)不受英国媒体报道软件拖累的人。
硬件(Hardware)规格和包装
Energizer P550S的包装不同于任何其他价格水平(price level)的产品。盒子由金属制成，具有(metal and suggests) 坚固性和耐用性(ruggedness and endurance)。
打开金属容器后，您会看到手机，位于黑色纸板盖(cardboard cover)下方。
在手机下方，您会找到一本小手册、一个可在欧洲(Europe)和英国使用的模块化充电器、用于打开(modular charger)SIM 卡托盘(SIM tray)的销钉和一对耳塞。遗憾的是，虽然手机支持快充，但随机附送的充电器只能提供5V的电压，不足以进行快充。根据“坚固”的形象，您还可以在包装盒中找到玻璃屏幕保护膜。(glass screen protector)这是一个很好的补充，即使智能手机带有预先贴上的保护膜。玻璃保护器(glass protector)比塑料薄膜更具抵抗力并且可以承受更多的惩罚。更重要的是，在发生事故时，它将冲击力分散在更大的表面上，从而增加了屏幕在冲击中幸存的机会。
Energizer Power Max P550S是一款相当大的手机，尺寸为 6.07 x 3.08 x 0.37 英寸或 154.3 x 78.3 x 9.4 毫米宽x深(x depth) x 高(x height)。它又厚又重，重量为 7.16 盎司或 203 克。然而，它有一个全金属机身(metal body)和一个 5000 mAh 的大电池(mAh battery)，所以重量对于知情的买家来说不会感到意外。
屏幕是具有高清分辨率(HD resolution)的 5.5 英寸触摸屏显示器。这么大的屏幕上只有 1280 x 720 像素，像素密度(pixel density)很低，大约为每英寸 267 像素。其余规格同样令人印象深刻。该处理是在具有四核 1.3 GHz Cortex-A53 CPU、Mali-T720 GPU和 2GB RAM的(RAM)Mediatek MT6737 芯片组(Mediatek MT6737 chipset)上完成的。虽然低端，但这些组件的功能足够强大，可以在不严重影响用户体验的情况下在Android上运行常用应用程序。内部(Android)存储空间(storage space)足够，16GB，还可以通过添加最高 64GB 的 microSD 卡进一步扩展。这Energizer Power Max P550S是一款双卡手机，与大多数双卡手机一样，microSD卡(microSD card)占据了第二个SIM卡槽(SIM slot)。
如前所述，不可拆卸电池的容量为 5000 mAh。这比普通手机电池(phone battery)的容量多 30-40% ，但要以重量和尺寸(weight and size)为代价。主摄像头使用带自动对焦和LED 闪光灯(LED flash)的 13MP 传感器，能够以 720p 的分辨率以每秒 30 帧的速度录制视频。它缺乏光学图像稳定(image stabilization)功能，但确实具有软件稳定功能(software stabilization feature)。前置摄像头(front camera)分辨率为5MP，定焦，还可以录制视频。
Energizer Power Max P550S使用两个 nano-SIM 卡，可以连接到GSM / HSPA / LTE移动网络。连接选项包括 802.11 b/g/n Wi-Fi、GPS、蓝牙和 USB OTG(Bluetooth and USB OTG)。Type-C USB 端口(USB port)是一个很好的补充，而在传感器部门，所有的盒子都经过检查：加速度计、指南针、光、陀螺仪传感器都存在。指纹读取器(fingerprint reader)位于手机背面。

除电池容量外，(The )Energizer Power Max P550S的规格并不引人注目，并且针对入门级位置。包装很漂亮，激发了坚固性和耐力。( specs are, with the exception of the battery capacity, unspectacular and aimed towards an entry-level position. The package is good looking and inspires solidity and endurance.)
设计和建造质量
拿起智能手机的那一刻，您就会感受到它的坚固性。按照今天的标准，它很重，而且也很厚。机身采用的铝合金没有拉丝，所以谈不上优雅和好看。从好的方面来说，指纹和污垢不是问题，因为手机不容易弄脏。
Energizer Power Max P550S的正面在上部装有光和接近传感器(light and proximity sensors)、5MP 摄像头、LED 闪光灯(LED flash)和耳机。
在屏幕下方，您可以找到（有点令人失望的）物理电容式按钮。物理按钮会占用屏幕空间，虽然将按钮放在固定位置对人体工程学来说稍微好一些，但趋势是将它们包含在屏幕上。这些按钮没有背光，因此您将在光线不足的情况下按盲，没有明确指示按钮的位置。
智能手机底部装有单声道扬声器(mono speaker)、Type-C micro-USB 端口和麦克风。手机顶部只有 3.5 毫米音频插孔。
在手机的右侧，您可以找到音量按钮和电源按钮(power button)，而左侧只有SIM 卡托盘(SIM tray)。
Energizer Power Max P550S的背面是扁平的，边缘是圆形的，相机周围有一个小边缘。除了Energizer 标志(Energizer logo)和带有手机IMEI码的贴纸外，唯一存在的其他功能(feature present)是小型指纹读取器(fingerprint reader)。这款手机看起来有一个可拆卸的后盖，但那个时代早已不复存在。
Energizer Power Max P550S 的设计非常通用。厚度不是一个真正的问题，唯一真正的抱怨是重量，但手机很坚固，金属机身在处理时感觉很好。(The design of the Energizer Power Max P550S is as generic as it gets. Thickness is not a real issue, the only real complaint would be the weight, but the phone is solid and the metallic body feels nice when handled.)

Review Energizer Power Max P550S: The simple smartphone with a large battery
You've moѕt likely heard of Energizer. It sells batteries, right? True, but it has also become a smartphone brand. Avenir Telecom, a French company that has received the rights to use this brand name, started selling mobile phones under the Energizer name back in 2015. This year, they released a new portfolio of smartphones and feature phones. The common theme that unites them all (except their brand name), is the battery and the autonomy it provides. In this review we evaluate the Energizer Power Max P550S, a low-budget Android smartphone which boasts a 5.000 mAh battery - quite large by today's standards. Let's dig in:
Energizer Power Max P550S: who is it good for?
The Energizer Power Max P550S is an excellent smartphone for:
- Users who need a solid phone with a stock Android operating system
- People who want long battery life from their smartphone
- Buyers on a budget
Pros and cons
We liked the following about the Energizer Power Max P550S:
- Amazing battery life
- Solid design with a full metal body
- No unnecessary applications are installed
- It has an untouched Android operating system
However, there were also some negatives to consider:
- The smartphone is very heavy
- The screen's color reproduction is not as good as on other smartphones with a similar price
- The included headset is of poor quality
Verdict
The Energizer Power Max P550S is a simple, easy to use smartphone for low-budget buyers. While the phone is heavy, its outstanding battery life may be a decisive quality for some users. The camera is mediocre, the phone is sturdy but unremarkable as far as design goes, and while we usually enjoy the clean Android operating system, the experience with the Energizer Power Max P550S convinced us that, sometimes, less is just… less. This smartphone is a good fit for people who want a cheap smartphone, with a long battery life and a clean Android distribution that is not weighed down by bloatware.
Hardware specifications and packaging
The Energizer P550S comes in a package that's different from any other offering at its price level. The box is made from metal and suggests ruggedness and endurance.
Upon opening the metallic container, you will see the phone, underneath a black cardboard cover.
Underneath the phone, you find a small manual, a modular charger which allows it to be used both in Europe and in the UK, the pin for opening the SIM tray and a pair of earbuds. Unfortunately, although the phone supports fast charging, the supplied charger only delivers a voltage of 5V, insufficient for fast charging. In line with the "ruggedness" image, you also find a glass screen protector in the box. This is a nice addition, even though the smartphone comes with a pre-applied protective film. The glass protector is more resistant and can take much more punishment than a plastic film. More importantly, in case of an accident, it dissipates the force of impact over a larger surface, thus increasing the chances of the screen surviving the impact.
The Energizer Power Max P550S is quite a large phone, at 6.07 x 3.08 x 0.37 inches or 154.3 x 78.3 x 9.4 mm in width x depth x height. It is thick and heavy, with a weight of 7.16 oz or 203 grams. However, it has a full metal body and a large 5000 mAh battery, so the weight won't come as a surprise for informed buyers.
The screen is a 5.5-inch touchscreen display with an HD resolution. With only 1280 by 720 pixels on a screen this large, the pixel density is low, roughly 267 pixels per inch. The rest of the specs are equally unimpressive. The processing is done on a Mediatek MT6737 chipset with a Quad-core 1.3 GHz Cortex-A53 CPU, a Mali-T720 GPU and 2GB of RAM. Although low-end, these components are sufficiently powerful to run the usual applications on Android without severely affecting the user experience.The internal storage space is sufficient, 16GB, and it can be further expanded by adding a microSD card of up to 64GB. The Energizer Power Max P550S is a dual-SIM phone, and as with most dual-SIM phones, the microSD card occupies the second SIM slot.
As mentioned before, the non-removable battery has a capacity of 5000 mAh. That's 30-40% more capacity than your average phone battery, at the cost of weight and size. The main camera uses a 13MP sensor with autofocus and a LED flash, capable of recording video at a resolution of 720p with 30 frames per second. It lacks optical image stabilization, but it does have a software stabilization feature. The front camera has a resolution of 5MP, fixed focus and is also capable of recording video.
The Energizer Power Max P550S uses two nano-SIMs and can connect to GSM / HSPA / LTE mobile networks. Connectivity options include 802.11 b/g/n Wi-Fi, GPS, Bluetooth and USB OTG. The type-C USB port is a nice addition, while in the sensors department all boxes are checked: accelerometer, compass, light, gyro sensors are all present. The fingerprint reader is located on the back of the phone.

The Energizer Power Max P550S specs are, with the exception of the battery capacity, unspectacular and aimed towards an entry-level position. The package is good looking and inspires solidity and endurance.
Design and build quality
The moment you pick up the smartphone you feel its sturdiness. It is heavy by today's standards and pretty thick as well. The aluminium alloy used for the body of the phone is not brushed, so we can't really talk about elegance or good looks. On the upside, fingerprints and dirt aren't a problem, as the phone does not get smudged easily.
The front of the Energizer Power Max P550S houses, in the upper part, the light and proximity sensors, the 5MP camera, the LED flash, and the ear speaker.
Underneath the screen, you can find the (slightly disappointing) physical, capacitive buttons. Physical buttons take space away from the screen, and while while having the buttons in a fixed position is slightly better for ergonomics, the trend is towards including them on the screen. The buttons have no backlighting, so you'll be pressing blind in low light conditions, with no clear indication of where the buttons are.
The bottom of the smartphone houses the mono speaker, the Type-C micro-USB port and the microphone. The top of the phone houses only the 3.5 mm audio jack.
On the right side of the phone, you find the volume buttons as well as the power button, while on the left side there is only the SIM tray.
The back of the Energizer Power Max P550S is flat, with rounded edges, and a small rim around the camera. Apart from the Energizer logo and the sticker with the phone IMEI codes, the only other feature present is the small fingerprint reader. The phone looks like it has a removable back lid, but that age is long gone.
The design of the Energizer Power Max P550S is as generic as it gets. Thickness is not a real issue, the only real complaint would be the weight, but the phone is solid and the metallic body feels nice when handled.
On the next page, we test the Energizer Power Max P550S, its camera, we review the bundled apps, and benchmark the performance of the device.
