We had the opportunity to wander through the secret chambers of Oppo’s factory in Shenzhen, China. Specifically, its quality lab also known as Dante’s Inferno for all Oppo smartphones.
And unlike other phone makers who like to keep things hush-hush, Oppo is out and proud about the extremes they push their phones to in their torture lab for the sake of perfection.
Phonemakers, watch and learn. This - is how you do a factory tour.
It might not look like there’s much going on here from far, but press your nose up against the glass and you’ll see that the phones have been pinned down and have little rods intently jabbing away at the power and volume buttons on the phones with a total pressure of 1 kg. This is obviously to simulate day to day use, especially when you're frustratedly trying to up the volume on an important call.
Rinse and repeat some 100,000 times before the phone is released and checked to see if function is intact.
Hard knock life
And of course, who can forget the common butter-fingered drop or Bendgate? A number of tests simulating scenarios like keys pressing against your phone to when your phone is in your back packet are run, as well as the quintessential impact tests.
They’ve got 1-metre tall barrels that tumble phones 150 times, machines that drop phones on every side from a height of 7 cm (like if you were to suddenly lose your grip on your phone at the table), and also that dreaded freefall test of a minimum height of 1.2m.
The freefall test is done twice for the different corners and edges, and onto a marble surface just like the ones you’re likely to encounter in malls and homes, and then the phones are finally scrutinised to see if they’re still operating fine.
Of course, it’s not all just about the physical trauma that can be dealt to an Oppo phone. Even if you keep a really good grip on your phone for the rest of its life, there are still external factors that can affect its general health.
As such, environmental tests are run to see if factors like climate will affect the inner workings of the phone. After all, you don’t want to not have your phone work because of the high humidity where you live. The phones are shut inside a temperature and humidity chamber at 55 degrees celsius and 95% humidity for a total of 48 hours. So you know you can bring your phone into a sauna and not have it keel over on you (although that’s still not the best place for a phone to thrive).
For those who hate their gadgets heating up after prolonged use, you'll be glad to know that in the Oppo factory, electrostatic discharge (ESD) tests are also run to monitor the temperature of the phone when making calls to prevent it from heating problems and thermal damage. High temperature aging checks are carried out after keeping running cell phones in a room heated up to 40 degree celsius for 12 days. That's pretty intense.
Even the accessories aren’t spared the abuse. These machines are dedicated to flipping open and shut the leather cases - a total of 300,000 times over a period of seven days, to make sure the covers can withstand the wear and tear of typical use. At the same time, they're also testing the wake and sleep function of the screen.
Forged from the rough
And at the end of some 130 types of different tests that random phones from batches are subjected to, they’ll halt the entire production to get to the bottom of things should they find anything amiss.
