Before buying an IP68 device, these things need attention:
1, Most resistance testing is performed in fresh water. Devices aren't guaranteed to hold up to salt water, unless specifically stated from the manufacturer.
2, While showering with IP-rated devices isn't recommended, the device won't break if you forget to take it off. The device could begin to leak and become damaged with continued exposure however, and water damage may not be covered under the warranty.
3, Unless otherwise specified, most tests are carried out at temperatures between 15 and 35 degrees Celsius (60 to 95 Fahrenheit). Higher temperatures in places like saunas, steam rooms and hot tubs could damage the device. For example, the Pebble has been tested to work within the temperature range of -10 to 60 degrees C (14 to 140 F).
4, Make sure all flaps (such as those for charging ports) are closed before submerging your device.
5, Unless otherwise stated by the manufacturer, you should avoid pressing buttons on the device while it is underwater. This could allow water to enter into the casing and damage the device.
6, Make sure the device is completely dry before charging it.
Your buying guide for the best IP68 waterproof phones in 2018
Ulefone Armor 2: Best Value Rugged Smartphone
The Ulefone Armor 2 is one of a number of recently released rugged smartphones that offer significant upgrades over their predecessors at a very affordable price, far cheaper than either the S60 or the AGM X2. This 5.0-inch, dual-sim phone runs Android 7.0 Nougat and is powered by an octo-core 2.6GHz Helio P25 CPU with 6GB of RAM and 64GB of storage. With its expected IP68-rating, the Armor 2 can be submersed up to one meter underwater for an hour and is resistant to dust, dirt, and sand. The screen is full HD 1920×1080 constructed of Gorilla Glass 3 and the 4700mAh battery ensures all-day operation. The 16MP-rear and 13MP-front cameras allow underwater shooting with the waterproof shutter button. Other modern features include a front fingerprint sensor and USB Type-C port. Unique outdoor features include a barometer sensor and SOS button. It has good all-around specs, affordable price, high-quality rugged exterior.
Blackview BV9000 Pro: The best value-for-money ruggedized smartphone
Blackview released the rugged smartphone BV8000 Pro, which came as an overall improvement over the previous generation (a bigger battery, a better camera and more powerful internal hardware, as well as a more elegant case), but, it seems that the Chinese manufacturer decided to quickly release a new rugged handset and, while that may be a great thing for new buyers that get a larger variety of rugged smartphones to choose from, for those that already have a previous gen Blackview phone, it does seem like there may be a problem considering the future support of older devices.
Perhaps the Chinese market is a lot more competitive when it comes to this type of smartphones, so the manufacturer had to gain an edge over the competition, therefore it released the Blackview BV9000 Pro which, as expected, borrows some elements from the flagship devices of 2017, such as the larger screen, small bezels and dual cameras. That being said, let’s see if Blackview managed to harmoniously combine all of these new trending elements with a rugged case which will be able to survive a rough environment, while also keeping the price at an acceptable level.
DOOGEE S60: Rugged Smartphone with Superior Camera and Wireless Charging
The DOOGEE S60 is another current-generation rugged phone that has similar specs as the Armor 2 and surpasses it in a few areas. Like the Armor 2 it is an IP68-rated dual SIM phone running Android 7.0 with the same CPU and memory setup and a fingerprint sensor. What differentiates it is the larger 5.2 FHD display with Gorilla Glass 5, the 21MP rear camera with a larger Sony IMX 230 sensor, 5580mAh battery, and wireless charging. Also the S60 has a traditional headphone jack while the Armor 2 requires a USB Type-C to 3.5mm headphone adapter cable (which is included). Unlike the Armor 2 it has a micro USB charging port. Plus it offers dual SIMs plus dual standby, a 24W quick-charge charger, NFC and even wireless charging (but no wireless charger). It is crammed with sensors and tools as well, which will come in useful for handymen (and women): there’s a barometer, a gyroscope, a coulomb meter, a sound level meter and even a bubble level.
