The Doogee S90 is a rugged device that's perfect for anyone in need of a device that can withstand extreme conditions.


First impressions and design

Huge device encased in a plastic and metal "armour" The heaviest phone we've ever tested Clip-on modules make it useful for specialised tasks

The Doogee S90 is a big phone. The 6-inch screen, built with Gorilla Shockproof glass, is covered in ablack plastic and metal casing. The armour-like design allows the Doogee S90 to withstand accidental drops to any hard surface.

Doogee S90 screen The Doogee S90 is a bulky, heavy device.

On the sides, you'll find a large power button next to the volume rocker on the right but also a hardware camera shutter button. Strangely, this doesn't work as a camera launcher when the phone is on standby and the screen is off.
This dedicated button also operates the camera in underwater mode.

On the left side, you'll find an additional multipurpose button that can be customised to switch on the torch, launch the camera or any app of your choice. As with the camera button, the multipurpose button is disabled when the phone is locked limiting its usefulness.

Buttons aside, it is the ruggedness of the Doogee S90 that is the real selling point and more specifically, its IP69K rating. Unlike your average premium device which is usually rated with the IP68 standard the S90 has a far superior IP69K rating. This means it's not only capable of withstanding water submersion and heavy dust, but it's also resistant to high-pressure water jets at a temperature of up to 80-degree celsius. The IP rating is accompanied by MIL-STD-810G certification - a series of tests including shock, vibration and exposure to extreme temperatures.

Ever fancied deep-cleaning your phone with high-pressure steam? With the Doogee S90, you can.

The 6.18-inch screen uses IPS technology, it is pin-sharp with a pixel density of over 403ppi, but colour rendering is average, and brightness is nothing to shout about.

No headphone socket, but it comes with an audio jack to USB adaptor if you want to use wired headphones.

First pioneered by the Motorola Z series, the optional clip-on modules offer an additional battery, a night-camera, a digital walk-talkie and a game-pad. The walkie-talkie and battery modules can be handy for a team that needs to operate in remote locations for long periods.


Camera

Great little snapper for documenting building work but best to rely on a better camera if detailed images are required.

Unlike mainstream smartphones, the quality of the camera should be a secondary concern for the Doogee S90. Nonetheless, the 16-megapixel/8-megapixel rear camera combination offers good-enough results for the type of use expected from this device. In good light, images look sharp as long as you don't zoom-in, and in low-light the camera compromises on colour fidelity and details on order to produce brighter images. The digital anti-shake works well with images mostly free of motion blur. One of the optional modules is a night-mode camera, which retails for around £50. This clips on to the back of the device and while it won't turn your Doogee in to true night-vision goggles, it gets good resultsat night or in dark environments.

Performance and battery life

The Doogee S90 doesn't run the latest version of Android, instead, its interface runs on a customised version of Android 8 Oreo. In terms of performance, the device is comparable to budget devices and has a generous 6GB RAM. Doogee S90 tools You'll find all the usual apps pre-installed as well as a set of tools such as Protractor and Height Measure. The Barometer (and altimeter) is another tool that makes the S90 standout. It is rare to see a air-pressure sensor on any phone nowadays.

Battery life is one of the main strengths of this device. The 5,000mAh is by far the biggest we have ever seen on any device and guarantees a few days of use and at least 3 weeks of standby.

Value and verdict

Very competitively price, even with the extra modules. Vey bulky device Largest battery you can buy Excellent choice of clip-on modules We'd like to see a more refined software interface

If you need to equip a team to work in a remote area and you're on a tight budget, the Doogee S90 is one to consider.

We expect it to retail at around £310 with optional modules costing between £30 for the extra battery and £50 for the Night Vision camera. This is a real bargain compared to equivalent offerings from more established brands like CAT. You do, however, get a somewhat clunky software implementation and some not so great design decisions.

Its bulk is the main factor to consider here. The decision to equip the S90 with such a large screen and still ensuring this level of toughness meant making this a very large device that's unsuitable for general use, even if you like the tough looks and massive battery.

If you're in the market for a robust device to take on your next Everest climb, give the Doogee a look. The optional modules are the real winner here and given how affordable they are, they give the S90 an edge over its competitors. While adding bulk to the device, the optional battery module, saves you from carrying an external power pack and the walkie talkie is a unique feature that would mean one less device in your toolbox.
