Raptor C5 – Cold Testing Our Rugged Android Smartphone

At Raptor, we like to test our devices just to see what they can really do. This time we’ve tested our brand new Raptor C5 against the cold and in this post, you can see the images and the result of those tests.

It’s not just our Raptor C5. We’re seeing a raft of devices being launched this quarter and that can only mean one thing… Testing! I personally love testing here because we do it right and we actually do it, unlike many other suppliers! I just love to see rugged kit doing its job and it’s also exciting to see when they’ll fail, as we test to failure here, just to see what they can really do. Even IP tests and MIL-STD are only guidelines, there’s no actual certification so showing you how we test gives some evidence.

The Raptor C5 is our answer to the fast developing breed of users who need a top feature-packed smartphone for personal use, but they need to use the same phone for work too. So it needs to be durable, inexpensive and supportable too.

The Raptor C5 isn’t actually designed to be super rugged, however, it turns out it’s not bad at all and rivals the best when it comes to pure rugged testing.  It’s IP68 water submersible, it’s dust tight and it has a 1.8M drop spec.

We thought it would be fun to share some of the temperature testing images with you.

Freeze testing

First, we freeze and then test.  The C5 worked great to -21C. At -30C only the Android capacitive buttons stopped working as expected.

We then rapidly heat and test for condensation. Because the C5 is IP68 we would expect zero condensation and this test was passed with flying colours.

We then heat beyond the same device to 60C and beyond, until we see issues with the screen. The capacitive screen is usually the first thing to stop working due to the way it works.

We then set the device at room temperature and test it again and in this case, the same C5 under all of these tests was found to be working perfectly again. We perform this test 6 times to be sure. This sort of test gives us valuable information on when the C5 will see issues that are temporary and recoverable.

The device was also tested with the battery and we then test the battery after the test.  We expect it to behave the same as it did before testing to indicate no-battery damage.

We also test to destruction so we know that heating the device to 100C starts to see permanent failure, at 120C you would actually start to see the solder on the board re-flow to give you an idea of the theoretical failure points.

We test all the time here. We do MIL-STD testing, but we also perform tests like above where we feel it puts the devices we sell under greater stress and also more real-life scenarios.
