OPPO’s Product Testing Facility Experience Showcases Behind the Scenes of Its Products: Mr. Phone Visits

OPPO QE Reliability Lab

OPPO is recognised for putting its products through rigorous quality checks before releasing them to the general public. This can be seen in the Reno6 and Reno7 Series and the more contemporary OPPO F21 Series. We got the opportunity to directly experience the procedure of this quality testing when we visited its OPPO’s Product Testing Facility (aka QE Reliability Lab in Noida). The encounter was unusual because we learned about an OPPO product’s process before being made available to an end-user. So, here we are, with our Lab experience; let’s get started.

OPPO’s End-to-End Quality Assurance Promise

So, what factors would a customer look for before buying a smartphone in 2022? It can be the quantity of high-tech smart features the device offers, or its beautiful design, which could be a compact one featuring all elements incorporated in a glass slab. Then there is product quality, which is another prominent factor that naturally tends to convert any consumer into a brand loyalist.

Innovation based on assured quality

OPPO is one such brand that has managed to develop that reputation with tight end-to-end quality controls that comprise almost everything from design to production and even after-sales. These quality control procedures significantly provide users with complete assurance when making an OPPO product purchase. The numbers of its consumers imply the same as there are close to tens of million OPPO users globally.

To prioritise product quality as its cornerstone for its long term success, OPPO came up with QE Reliability Lab in 2017 at the Greater Noida facility in India. The aim here is to maintain high standardised product quality across the organisation. The lab ensures testing products against the strictest quality requirements from the development phase to the mass production process. This means that the products must undergo multiple tests before being approved by the consumers who get their hands on them on purchase.

Dedicated designs make every promise a reality

Next comes the design, where to make improvements, the facility needs clear and detailed blueprints, which the product designers at OPPO provide beforehand. There will be a lot of thinking processes going on before they submit as they’ve to think ahead of the problems that workers at the facility might encounter during production/manufacturing.

Practical and durable process innovation

The next step would be design approval, wherein all innovative ideas might not get picked. OPPO here has a unique approach to commercialising new designs. The novel design would require hundreds, if not thousands, of trials that further comprise material selection, testing of the manufacturing process, quality verification, or months of rigorous testing. For instance, the OPPO F21 Pro Sunset Orange was finalised by testing thousands of materials; later, designers narrowed it down to potential six options. Finally, they opted for a lychee grain leather texture finish.

OPPO says that the designers further faced new challenges in bringing the grain leather texture finish to reality. In the process, OPPO had to create an innovative fibreglass leather produced by synthetic leather material combined with a plate that made its way to fit perfectly on the rear of the phone. This new design further eliminated the need for a mid-frame on the device, which traditionally supports the battery cover. The design made the device’s construction lighter and thinner without ditching its durability.

The recent OPPO F21 series production involved ten tested and modified polyurethane materials, six bridging layers, and five modifications. Further, to ensure the material withstanding capabilities against 100-degree Celsius heat and 1.5mPa of pressure for nearly four hours, OPPO engineers strengthened the leather polyurethane material on the device to fight 190-degree celsius and 20mPa of tensile strength.

Stringent testing of every detail – A look inside the OPPO QE Reliability Lab

Then comes the testing program from OPPO, which has two sides to it. Every phone here is subjected to a series of tests to detect any defective components or manufacturing flaws, for that matter. OPPO smartphones must pass over 320 experimental tests and six prominent tests to head to the next level. The QE Reliability Lab does some thorough testing, including torture testing, compressing years of typical use into a much shorter period.

Comprehensive general testing goes beyond industry standards

OPPO implies that its products are only deemed fit for buyers if they successfully pass the Series of rigorous quality tests. The testing here involves daily use case scenarios like waterproof testing, temperature tests, battery tests, display tests, and audio tests, among many others. Some of these tests can have higher standards than the industry average, only to ensure that OPPO products have excellent quality builds delivered to millions across the planet. These extensive tests ensure that OPPO products perform as expected in normal and harsh conditions. To give you an idea, the standard phone drop is set at one metre, wherein the industry standard is set at 0.8 metres only.

More information on these tests can be found below:

Testing for accidental drops

The OPPO QE Reliability Lab tests the phone in various simulated drop scenarios. To pass this test, the phone must survive the fall without any cracks or detached components. The simulation in the process involves traditional free-fall scenarios from multiple heights. The OPPO F21 Series, for instance, has gone through a height of one metre, and the simulation was done 12 to 24 times. Then there are three extreme use case scenarios that involve the same methods but from a slightly higher perspective, i.e. 1.5 metres. The free-fall drop surfaces include six surfaces, eight corners, and twelve edges.

It involves a more casual dropping use case; it could be from a table or bed in an everyday scenario. The F21 Series is said to have dropped 28,000 times from a height of as little as ten centimetres.

Micro Drop Test

The F21 Series also underwent the micro drop test involving products falling on unusual surfaces like Sandpaper, the roughest surface for any phone. These tests typically include the smartphone without a screen protector or any external case, for that matter.

Tumble test

The other common scenarios for any device can comprise phone slipping or undergoing a strong collision, and this tumble test in the lab tests precisely that. The OPPO F21 series also experienced this wherein it was placed inside a one-metre long case that rotates at a speed of 3.5 revolutions per minute for 15 revolutions. The simulation here is equivalent to a phone being dropped from one metre, 150 times.

Waterproof testing

This is another effective procedure when it comes to product testing. While the drop tests are made to prevent potential damage on the outside, waterproof testing is essential as it can bring a whole set of new problems from the inside. The recent OPPO F21 Series has also undergone the same as it features IPX4 standard rating. The testing simulates a heavy rainfall wherein the phone is sprayed with water on all its surfaces at a 75-degree angle in the lab. The testing is carried out in the same way during a call or while playing a video.

The other waterproof test involves devices placed underwater for up to 20 centimetres for 30 seconds. After the water drop test, the device is further wiped dry and kept aside for three days, and then it will be disassembled to check whether any main PCB interface has seen any damage or corrosion. Again, the OPPO F21 Series has gone through the same before public release.

Testing for each scenario – Environments across India

The phone should perform well and adapt to different climates, temperatures, and environments across the globe. And to test this, the Environmental Work test at the OPPO Lab comes into play. The test is conducted with the phone stored at a specific temperature and humidity level for a particular number of days. After that, the device should typically perform after undergoing the process, and the device’s RF indicators should meet the standards, then the device gets a pass. The necessary tests in the Environmental work test include the following:

Temperature Shock Test: In this test, the phone is stored at a low temperature of around 40-degree Celsius and in a warm condition of 75-degree Celsius for 300 hours(~14 days). The device then undergoes a temperature shock condition as the temperature changes every hour.

Storage & Ageing test: This is a humidity test for the phone which involves testing under 95-degree humidity conditions at 65-degree Celsius for 14 days. The test analyses all device functions, including the camera and charging, and the device gets tested in both switch off and working conditions.

Salt Spray Test: This is also part of a humidity test that involves salinity. The OPPO F21 Series underwent the test wherein it was sprayed with a 5% salt solution for two hours before placing it in a hot, humid environment that includes 50-degree Celsius and 95% humidity. The device, amongst others, will be used in coastal areas where salinity is naturally observed. The phone must show no signs of damage and normally perform to pass the test.

Cosmetic & Sweat test: Aside from the extreme conditions from the outside world, human sweat and cosmetics left on the phone’s surface by users tend to cause damage too. The OPPO F21 Series was put through a Sweat Test and a Cosmetics Test to see if it could withstand these problems.

In the sweat test, the phone is put through its paces in the Perspiration Test by being wrapped in a fabric soaked in fake sweat. After which, it is placed in a hot and humid atmosphere (50°C and 95% humidity) for 48 hours (~two days). The phone is then set aside for 24 hours before being checked for regular performance and evidence of corrosion on the device’s inner and outside construction. In the cosmetic test, as the name implies, the device is put through a selection of cosmetics on the phone’s surface and is placed in a hot and humid environment for 24 hours.

Static Tests

There are arid regions across the globe apart from coastal and humid areas. The former regions are also a common concern for smartphone components as the static electricity in those areas may cause an increase in friction. To tackle that, the OPPO F21 series was tested with a ±8kV contact discharge and a ±12kV air discharge. After the tests, the device should function normally with RF index parameters in the standard place. Besides, OPPO devices are also tested for eight hours in extreme dust case scenarios.

Temperature Test

Devices tend to heat up internally during resource-intensive tasks or while generating electrical power within themselves, especially in 5G-compatible devices. And OPPO believes that shouldn’t be a problem as its devices like the recent OPPO F21 series have been equipped with advanced software and hardware technologies to control any rise in temperature within the device with proven real-life scenarios.

OPPO has partnered with chipset makers like Qualcomm and MediaTek to test and balance the phone’s overall power consumption. Not just that, the recent OPPO F21 Series have also been equipped with large vapour cooling chambers to control heat dissipation.

OPPO suggests that it had further conducted extensive research into users’ habits to optimise the vapour cooling system. This involved identifying the device section that users typically hold while using and ideally placing the cooling system at those appropriate places. OPPO has also figured out which part of the device tends to get warm overusing at more extended periods and figured out a thermal isolation frame as part of the design that’s witnessed in the recent OPPO F21 series.

Specific Special Quality Control Tests

OPPO also undertakes stricter tests to ensure that novel design components are durable and practical. The Fibreglass Leather on the OPPO F21 Pro Sunset Orange, for instance, has been put through rigorous lab tests that included rubbing the material with an alcohol-soaked pad, a rubber eraser, and a denim swatch over 5,000, 10,000, and 200,000 times, respectively. The company ensures that its creative designs are sturdy and resistant enough to fulfil its requirements by replicating daily wear and tear in this way.

The Orbit Light feature was introduced recently on the OPPO F21 Series, a light ring surrounding one of the rear camera modules. OPPO has undergone over twenty uniform light scheme tweaks, thousands of uniform light detection tests, and other unique testings on this feature. The Orbit Light was proved to have a lifespan of over 50,000 hours in the standard test setting (25°C, 60% humidity, 10mAh). OPPO proudly believes that even the tiniest innovations provide a dependable, fault-free experience using these specific quality control tests.

Conclusion

Any OPPO product must undergo this rigorous sequence of tests and challenges to be quality assured for market sale and reach users’ hands. This attention to detail makes the OPPO product a rigid device that can take on any task alongside the user.
