The Doogee S90 comes with everything You Need, in a phone. Mix, match, and swap. S90 far exceeds typical phones with its innovative modular design. It’s a powerful night vision camera, a professional rugged walkie-talkie, and even a portable game console. In addition, a 5000mAh power bank module is good for 26 hours of usage. Slide any S90 module into the slot and it just works instantly.
Design
The Doogee S90 is a tough Smartphone Inside And Out. The DOOGEE S90 is highly waterproof, dustproof and shockproof. It’s rugged enough to work under 1.5m (5 feet) deep water for 2 weeks. It can survive strong temperatures, drops & transport shocks, humidity, mold, salt spray corrosion, explosive gas, vibration and more. No matter where you go and what your mission is, it can handle it. It’s the toughest smartphone ever made.
Hardware
The Doogee S90 In addition to its new Modular design innovation, S90 is also the best DOOGEE Rugged phone we’ve ever made. Driven by an Helio P60 Octa-core chipset and Mali-G72 MP3 GPU, the S90 is up to 25% more energy efficient with a 30% CPU operating boost compared to the last generation. Powered by multi-core AI Processing Unitand NeuroPilot AI technology, S90 is able to deep learn user behaviors and perform facial recognition, scene identification, and more advanced features.
Both clusters can operate at up to 2GHz and are supported by a Mali-G72 GPU. The chip can do LTE and supports up to 8GB of LPDDR4 memory (the S90 has 6GB on-board). Note that the MT6771 also sports a Neural Processing Unit from Tensilica which may come in handy for AI workloads in the future. As one would expect, you can use a microSD card to add to the 128GB on-board storage, although that means sacrificing one SIM card. The S90 has NFC (great for payments), 802.11ac Wi-Fi, plus the ability to charge the sealed 5050mAh battery wirelessly, leaving the Type-C port untouched (a great idea as this is a rugged phone).
Features
The S90 performed spectacularly in our tests, racking some of the best numbers we’ve seen in our benchmarks, surpassing previous Mediatek silicon by a wide margin. One can safely assume that this phone will be able to sail through most applications without much trouble. The phone supports 29 bands in all and provides dual 4G SIM standby. It doesn’t run the latest version of Android, though, instead sticking to a customized version of 8.1 Oreo. The latest firmware is dated December 2018 which is a good sign.
Doogee has equipped the S90 with a ‘survival software pack’ which is essentially an array of useful apps that includes a sound meter and a barometer, among other things. Similar app packs – probably from the same developer – are often available on other rugged smartphones. The device’s description alludes to the presence of a hardware coulometer and we confirmed with Doogee that this is the case. However, we didn’t find any apps on the device that would make use of this particular feature.
As for the modules, they worked as described, although they will add to the weight and detract from the general portability of the S90. Note that the modules aren’t IP68 certified and may break if dropped. The night vision camera allows you to capture shots in low light (but not in complete darkness), though it adds noise to the final photo. It uses a 2-megapixel Sony IMX291 camera sensor and amplifies light it receives by a factor of 12. The 5000mAh power module turns the S90 into a 10Ah phone, but adds another 138g to the device, also turning it into a brick.
