Industry sources claim the 5.5-inch iPhone – referred as the “iPhone Air” – is facing production issues, so it will be delayed until next year, as Apple’s battery providers are unable to meet the company’s requirement to cut almost a third of the battery’s thickness.
The same sources say the 5.5-inch iPhone will be very thin, and so the battery must measure around 2 mm, which compares to up to 2.8 mm thickness of the batteries found in current smartphones in general.
Due to this challenge, the release of the 5.5-inch model will be delayed until 2015. It is worth noting here that the branding, iPhone Air, is not yet finalized, but it would be interesting to see if Apple indeed chooses to go with the “Air” name, just as it did with the iPad last year.
The Taiwanese rumour apparently corroborates an earlier whisper claiming that Apple’s 5.5-inch iPhone 6 is facing delays due to in-cell production technology challenges.
