A14 Bionic has impressed us with its exceptional performance and the iPhone 12 series is definitely one of the highest performing devices in the market today. Without doubt, the A15 Bionic will push things one step further and its first production will start on May. Apple’s next chipset will be for the iPhone 13 series and as usual, TSMC will be the one that makes the chipset. Based on reports, it is possible that the iPhone 13 series will be available in September. With current shortage of computer chips, we could be hopeful that things will get better soon. Reports also told us that the N5P process for the A15 Bionic production uses the improved 5nm manufacturing technology. It means, the A15 Bionic will be more efficient and faster than its predecessors. However, because the A14 Bionic is already sufficiently powerful for any mobile task, the main focus of A15 Bionic could be on power efficiency.
At the moment, no chipset, including Snapdragon 888 can really compete with the A14 Bionic chipset. So, it is acceptable if the A15 Bionic only delivers slight improvement in performance. If the iPhone 13 will have 120Hz display and 5G data connectivity, it is better for Apple to focus more on power efficiency. Although the 120Hz OLED LTPO display will be available only for iPhone 13 Pro and Pro Max, the use of both high refresh rate and 5G connectivity may deplete battery juice faster. It will be interesting how the A15 Bionic chipset will be like. Rumours also indicated that rear-facing cameras of the iPhone 13 may not be a huge improvement, compared to the iPhone 12 series. However, the primary camera may have larger aperture, as reported by Ming-Chi Kuo. He revealed about details regarding to supply pipeline of lenses for Apple. Apparently, the iPhone 13 Pro Max will have lens with f/1.5 aperture, which is useful for wide-angle imaging, probably for the more expensive Pro Max version. It also means that the iPhone 13 Pro Max will offer increased bokeh and better night-time photography.
The more affordable regular iPhone 13, iPhone 13 Pro and iPhone 13 mini may have the same wide-angle lens with f/1.6 aperture. They may also include 7P lens stack to reduce chromatic aberrations and optimize light collections. Eventually, all future iPhone models will transition to 7P technology for rear-facing cameras. Ming-Chi Kuo also told us that Sunny Optical from China will be the supplier for lenses with 7P components. The shipment of wide-angle lenses with 7P components for iPhone 13 will begin on the Q2 2021. When it comes to dedicated imaging hardware, there may not be any big change with the iPhone 13. Kuo further said that the iPhone 13 could have unibody design with increased design robustness. The periscope technology for the telephoto lens should be more efficient and compact. The iPhone 13 may still have the controversial notch on the front, but it should be narrower. On the back, the camera bump could have a brand-new appearance. The improved OIS feature should keep images sharp and subjects centred.
