Apple places its merchandise by plenty of checks throughout the growth course of, supposed to make sure they’ve an extended and dependable life even in difficult circumstances. The corporate checks at the very least 10,000 iPhones previous to launch in an try and cowl all of the bases.
It’s not usually the iPhone maker lets outsiders into its labs, however Apple invited a few of these attending WWDC 2025 to go to one to see for themselves the circumstances it expects its devices to outlive …
To be clear, it’s not the primary time Apple has let outsiders have a look round considered one of its sturdiness testing labs. MKBHD final 12 months acquired his personal tour, and shared some movies from that. However Counterpoint has this 12 months supplied a extra detailed description of what these checks contain.
They fall into 4 classes:
- Environmental
- Water
- Impression
- Vibration
Environmental
These checks are supposed to duplicate the local weather challenges confronted by gadgets that are utilized in 175 nations around the globe.
We witnessed salt publicity checks working for so long as 100 hours, excessive mild depth publicity, and publicity to mud from the Arizona desert to research what occurs when high quality sand particles enter the iPhone’s audio system or the charging port. Some checks within the case of AirPods contain producing synthetic variations of sweat and earwax. These checks are additional tweaked to think about a few of the system utilization information Apple has entry to, which highlights the labs’ complicated efforts to align with altering environments.
Water
Safety in opposition to water and dirt is measured by IP rankings, requirements set by the electronics trade with particular standards for every.
For instance, the iPhone 16 Professional has an IP68 ranking, the very best accessible. This implies it should present no ingress of mud in any respect in any of the checks, and should proceed working usually after being submerged in water to a depth of six metres for one hour.
Apple’s water checks begin gently then ramp up.
The IPX chamber take a look at begins with a primary drip ceiling take a look at to simulate rain and primary water ingress. That is adopted by simulated water stress by jets round all corners of the product. As soon as the product passes this take a look at, it turns into eligible for the IPX5 ranking.
Then comes the high-pressure water splashing at a distance, which provides the product IPX6 ranking, and eventually, a pressurized tank simulating water depths provides the product IPX7 and IPX8 rankings on its profitable submersion as much as one meter and 6 meters, respectively.
The IP rankings relate solely to mud and water, however Apple’s checks additionally embrace different commonly-encountered liquid hazards, like sodas, juices, sunscreen cream, and fragrance.
Drop checks
YouTubers would possibly perform a small variety of unscientific drop checks for enjoyable and views, however dropping your iPhone in the actual world is a really totally different matter. Each drop is totally different, relying on the peak, the fabric it lands on, and the exact angle of influence.
Apple goals to duplicate this monumental number of drop hazards throughout its testing.
To get nearer to the real-life situations, Apple has developed a robotic that drops gadgets at totally different angles and even on totally different surfaces, together with particle, granite and asphalt boards. Furthermore, every drop is analyzed by an app that’s accessed by Apple engineers.
Vibration
Whereas a much less apparent hazard, an iPhone wants to have the ability to survive issues like sitting within the pannier of a bike travelling over tough floor. Once more, the variety of variables concerned is big, so Apple’s checks intention to show gadgets to a variety of frequencies.
These frequencies are simulated by a vibration desk to create totally different shaking environments and impacts {that a} product might even see throughout transit or different real-world circumstances, together with for various producers of bikes. The vibration desk had merchandise tied on prime of it for an prolonged time period and was subjected to totally different frequencies.
