The iPhone 17 features a significant durability upgrade with its new Ceramic Shield 2 technology, which protects both the front and back of the device. Apple hevder at dette nye keramiske skjoldet gir 3 ganger bedre ripebestandighet på frontdisplayet sammenlignet med tidligere iPhones. Additionally, the back glass, now also covered with Ceramic Shield 2 for the first time, has 4 times better resistance to cracks than earlier models. This extended use of Ceramic Shield 2 enhances durability by making the iPhone 17 more resistant to both scratches and drops, positioning it as Apple's most resilient iPhone to date.
This Ceramic Shield 2 is described as a tougher-than-any-smartphone glass or glass-ceramic material with a unique Apple-designed coating that not only improves scratch and crack resistance but also reduces glare through improved anti-reflective properties. The screen's scratch resistance improvement is especially notable because it means the display will maintain clarity and integrity longer under regular use conditions like being carried in pockets with keys or other abrasive materials.
Before the iPhone 17, Ceramic Shield was typically limited to the front display, but Apple has extended it to cover the back glass, which historically has been a more fragile element in smartphone design. Denne utvidelsen lover større beskyttelse mot ryggglass som knuses på dråper, en vanlig sårbarhet i premium smarttelefoner. Combined with the phone's forged aluminum alloy body, this innovation aims to deliver a significantly tougher build than the previous titanium models.
Apple also emphasizes that the iPhone 17 maintains an IP68 water resistance rating, allowing it to survive submersion up to 6 meters for 30 minutes, which complements the Ceramic Shield's physical toughness by protecting against liquid damage as well.
Despite earlier challenges, Apple's Ceramic Shield 2 now includes an anti-reflective coating that enhances outdoor visibility by reducing glare and improving contrast, with the iPhone 17 Pro model's display reaching an industry-leading peak brightness of 3,000 nits. Dette belegget bidrar også indirekte til å screene holdbarhet ved å legge til et lag som hjelper til med å forhindre mikroskraper og slitasje.
IPhone 17s keramiske skjold 2 -holdbarhetskrav støttes av praktiske forbedringer i ripebestandighet sett i tidligere versjoner. Reviews of the iPhone 16 Pro's updated Ceramic Shield glass described it as nearly unscathed after extended use (like seven months) compared to older models with the original Ceramic Shield that showed visible scratches. Den nye iterasjonen lover å bygge videre på denne forbedrede levetiden og seigheten for å tåle daglig slitasje mer effektivt.
Oppsummert er Ceramic Shield 2 på iPhone 17 et sprang fremover i smarttelefonens holdbarhetsteknologi av:
- Gi 3 ganger bedre ripemotstand på frontskjermen sammenlignet med tidligere versjoner.
- Tilbyr 4 ganger bedre sprekkmotstand på bakglasset, en første for keramisk skjolddekning på iPhones.
- Innlemme et nytt antirefleksbelegg som forbedrer synligheten og motstanden mot utendørs skjerm mot mikroabrasioner.
- Å bli sammenkoblet med en robust kroppsramme for aluminium som forbedrer fysisk holdbarhet ytterligere.
- Opprettholde høyt vann- og støvmotstand med en IP68 -rangering.
