MADRID, 19 Sep. (Portaltic/EP) –
Before reaching the points of sale, smartphones pass through different quality tests to guarantee resistance to shocks, drops or temperatures, among other variables. Each manufacturer establishes its criteria and many have their own laboratories with the most demanding tests. This is the case of OPPO, which in 2008 created OPPO QE Reliability Lab with the specific purpose of “maintaining high and standardized product quality.“
“From the beginning of the product development phases, right through to the production process, OPPO QE Reliability Lab is tasked with testing products to the highest quality standards. This means that OPPO products can only reach consumers if they have successfully passed a rigorous 150 exam test, which includes environmental, mechanical stress, durability, performance tests, among many more “, explain the company’s experts.
Smartphones have become essential for everyday life, so they must be able to withstand a wide variety of situations that occur on a day.to.day basis. With this idea in mind, OPPO has tested the Reno6 series terminals in a variety of extreme conditions to be able to ensure that the product can withstand almost any situation that may arise.
28,000 FALLS AND TURNS AT 3.5 REVOLUTIONS PER MINUTE
Dropping the ‘smartphone’ is possibly the most common accident. To make sure it can survive most drops, the OPPO QE Reliability Lab has tested the Reno6 in a variety of simulated drop scenarios. To successfully pass this drop test, the phone must survive the exam without cracks, no dislodged components, and no malfunctions–
The drop test simulates a free fall scenario from various heights. In this specific case, it was set at a height of one meter, which is 25 percent higher than the industry standard tests, which is 0.8 meters. This simulation was carried out between 12 and 24 times, making the phone fall on its 6 surfaces, its 8 corners and its 12 edges. To simulate even more extreme scenarios, the phone was dropped in the same way, but from a height of 1.5 meters.
However, on a day.to.day basis, the phone is much more likely to accidentally fall on more normal surfaces, such as a table or bed, in which the fall distance is much less than that simulated in the cases mentioned above. To test these most common situations, Reno6 series products were dropped 28,000 times from a height of 10 centimeters, a level much higher than the industry standard, which does it in a range of 5,000 to 10,000 times.
Beyond these common scenarios, this product also underwent what is known as a ‘Tumble Test’, to simulate a strong ‘smartphone’ collision. In this test, the phone is placed inside a meter.long casing that rotates at a speed of 3.5 revolutions per minute for 8 or 10 turns, to simulate the phone falling from a height of 1 meter 300 times. This more rigorous test mimics the conditions in which the phone could falling and hitting hard against a hard surface, thus guaranteeing that the final device is resistant to all possible daily falls.
RAIN AND TEMPERATURES FROM .40 TO 75 DEGREES
Another important specification is waterproofing and protection against rain, so the lab technicians simulate a “heavy” rain of 10 ± 0.5 L / min. During testing, the phone is sprayed with water on all four surfaces at a 75 degree angle and is also tested while the phone is playing videos or making a voice call.
To further ensure water resistance, the Reno6 series has also been tested at a depth of 20 centimeters under water for 30 seconds. After each test, the phone is wiped dry and set aside for three days before being disassembled to examine if any components show any signs of corrosion.
But mobiles are not only prepared against the rain, the ‘Environmental Work Test’ measures the performance of the product in extreme temperature and humidity conditions, ranging from .40 ° C to extremely hot conditions, of 75 ° C, for 7 days. OPPO terminals pass this test for 168 hours, more than double the industry standard, which is 3 days (72 hours). The phone is also tested to humidity and salinity, in environments up to 95% humidity.
In addition to the harsh external conditions, everyday aspects such as sweat or cosmetics can also damage mobiles– To test these possible problems, the product is subjected to a sweat test and cosmetic test, ensuring the absence of signs of corrosion on the internal and external structures of the device.
TENSION, TORQUE AND DURABILITY TESTS
Another common situation that smartphones face is physical pressure and twisting, usually when carrying phones in a pocket or bag along with other objects. OPPO has performed its torsion tests by rotating the product a thousand times with a torque level calculated based on the width and thickness of the phone. Also, a simulated weight of 25 kg has been applied to the devices, while adding additional weight blocks of between 15 and 40 kg.
On the other hand, to examine the ability of the phone to resist natural wear and tear, the mobile also undergoes a series of tests on the physical buttons and connector inputs. One of these tests involves using a force equivalent to 1 kg to press the buttons on the phone thousands of times to simulate natural wear and tear on these buttons over the life of the phone. For instance, the power button is pressed 20,000 times, the volume button 100,000 times, and the fingerprint key 300,000 times.
These are just some of the tests that state.of.the.art smartphones are subjected to, which must also have software and hardware that can limit and control any increase in temperature, as well as a cooling system in high processor or battery workload situations– A perfect balance that makes the user experience unique and that is achieved through dozens of tests that, normally, go unnoticed by the consumer.
