We have seen many smartphones with an IP68 rating. Generally, this rating means a device can resist submersion up to a maximum depth of 1.5m underwater for up to 30 minutes. Seems this is a must-be feature for any rugged smartphone. But we have never heard about the IP69 standard. A few months back Nomu announced it is going to launch a smartphone with an IP69 rating. It would be the upgraded version of its S10. Honestly, we have reviewed the Nomu S20 and S30. So the Nomu S10 Pro caused a huge interest in us. Moreover, the mysterious standard means the phone can be submerged in depths of under 2m for 1 hour and not sustain any permanent damage. This takes the ruggedness to the next level. So we just have to get a closer look at this phone and this new feature.
Nomu S10 Pro Appearance
Like many other rugged phones, the Nomu S10 Pro comes with an intimidating presence. The body is mainly made of shockproof rubber material supplied by Bayer AG, a German company. The corners are not rounded at all. The back is bulging. All holes and interfaces are covered with the same-material stubs. But all these are done to protect the phone as much as possible.
The overall body is black. But there are orange lines around the perimeter on the back as well as the front. We guess it’s been done to increase the visibility of the phone in darkness.
On the front, the Nomu S10 Pro carries a 5-inch screen. Of course, it’s not a full-screen but comes with a regular 16:9 aspect ratio. Plus, it provides a 720p resolution only. But as we are dealing with a budget-friendly rugged phone, it’s quite acceptable. It is covered with a Corning Gorilla Glass 3 to protect the display from minor scratches. There is no home button on the chin. So the only way to interact with the phone is done via touch keys.
The back panel carries a single camera sensor accompanied by a flashlight and a microphone hold. All these features are located vertically in the upper center area.
A SIM card slot is placed on the left side. This is a bit surprising because the most of rugged smartphones come with a removable rear panel. So the SIM card slot is usually placed under it. But the Nomu S10 Pro uses a common way for this feature. The slot supports two SIM cards, but you can scarify one of them in benefit of the storage expansion. As you guess, it supports DSDS (dual SIM dual standby) standard.
The unlock key and the volume rocker is on the right hand-side. At first sight, you should press hard to make them work. But in reality, a little pressure is sufficient to unlock the phone or increase/decrease the volume.
A 3.5mm headphone jack is placed on the top.
A micro USB port in on the bottom. Both interfaces are protected by caps.
Nomu S10 Pro Hardware and Performance
The Nomu S10 Pro is packed with an entry-level MediaTek MTK6737T chip. This chip can be found on the aforementioned Nomu models from the S line. So no need to dive into details we are already familiar with. But those who are not aware of this SoC, the MTK6737T is a quad-core chipset using 4 Cortex-A53 cores clocked at 1.5GHz and paired with a Mali-T720MP2 GPU at 600MHz, 3GB of RAM, and a 32GB of ROM.
The benchmark tests show the Nomu S10 Pro is a regular entry-level smartphone with a stable but not astonishing performance. It is capable of handling the most of daily tasks. But you don’t have to wait for more from this handset.
The phone comes with Android 7.0 out of the box.
Battery and Connectivity
This is not a Doogee phone with a monster-size battery. But its 5000mAh capacity battery is capable of providing a respectable life. Thus it will provide up to 2 days of a normal use or 10 hours of screen-on time. Also, it takes two hours to charge the phone fully.
As for connectivity, though the Nomu S10 Pro supports 4G LTE, the call quality can’t be compared with the top models. There are also 7 sensors and it lacks a gyroscope. Therefore the device is not compatible with VR headsets.
Nomu S10 Pro Camera
There is an 8MP camera on the back and a 5MP shooter on the front. So no need to wait for incredible shooting performance from this wallet-friendly rugged handset. But actually, we got way better photos than expected.
When there is a sufficient lightning, the Nomu S10 Pro will capture some decent-looking photos, but when it goes darker the noise level increases affecting the photos’ quality.
As for recording videos, this handset does it at 1080p resolution. But if you take videos via the front camera, the resolution will be 480p only.
IP69 Standard Tested
To show what IP69 rating means, the manufacturer has come with a few test videos. First, it puts two Nomu S10 Pro phones in two containers filled with water and Coca-Cola, respectively. Then it freezes both containers for 5 hours. Thereafter it breaks the ice. And voila, both models continue working as nothing happened.
In the second test, a beer bottle with a 1kg weight is dropped on the phone placed onto the floor from a height of 80cm. But the phone survives again.
Finally, in the third test, the Nomu S10 Pro was buried in the snow for 30 minutes. As you guess, after the testing time nothing strange happened with the phone. It continued working properly.
Nomu is not the only smartphone maker known for its rugged devices. There are many companies such as Blackview, Uhans, Ulefone, AGM, Doogee, and others. But this manufacturer is focusing on this niche only, while the mentioned companies come in with various models. That’s why the Nomu S10 Pro has opportunities to stand out. So it can be considered as one of the cheapest rugged handsets.
