**IPhone 17 Pro prošel extrémní zkoušku odolnosti z výšky 30 607 metrů**

RhinoShield, výrobce ochranných pouzder pro mobilní zařízení, a společnost Sent Into Space provedly nedávno experimentální test, při kterém iPhone 17 Pro padl z výšky 30 607 metrů nad severní Švédskem. Teléfono se podařilo zachránit a po příletu na zem fungoval bez problémů.

iPhone 17 Pro prošel extrémní zkoušku odolnosti z výšky 30 607 metrů

Cílem wasn't just to test how far an iPhone could fall, but to set a new Guinness World Record for the highest drop of a phone in a case on natural terrain. The launch took place on June 24 from Kiruna, Sweden, using a high-altitude balloon. Once over 30 km high, the iPhone was released and began a 25-minute descent without a parachute, without a protective container around it, and without any heating system to protect the device during the fall.

During the descent, the iPhone experienced extreme conditions, including temperatures as low as -60°C and changes in atmospheric pressure as it passed from the upper layers of the atmosphere to denser zones. However, the actual impact of the fall was not as dramatic as it might seem, as an object in free fall does not accelerate indefinitely. Air resistance increases as the object gains speed, reaching a maximum known as terminal velocity. For a spinning phone, this could have been around 50-160 km/h, depending on its orientation. So while the iPhone started its descent from a huge height, it likely didn't hit the ground at a speed much faster than after a much shorter fall.

After the impact, the next challenge was locating the phone. The tracking system narrowed the search area to about two kilometers, but the team needed over five hours to finally find the device. When they recovered the iPhone, the surprise was that it still worked. The record-keepers verified that it could be turned on and off, make calls, and take photos. Moreover, the exterior of the phone showed no visible damage. The Guinness World Record has been officially registered as the highest drop of a phone in a case on natural formations. The result turns an unusual advertising campaign into an extreme demonstration of durability.
