The old iPhone will be left without useful features of iOS 11
One of the main “chips” iOS 11 will be new compression formats (High Efficiency Image Format, HEIF) and video (H. 265, or HEVC, High Efficiency Video Codec). Due to this, the size of the pictures and videos will be approximately two times less compared to the current.
However, as noted by the media, to take advantage of it. So, shooting photos in HEIF and HEVC will be available only on iPhone 7, iPhone 7 Plus, new to 10.5 and 12.9-inch iPad Pro (running on A10 processor Apple Fusion or higher).
For hardware decoding HEIF photos and videos HEVC suitable device with a processor Apple A9 or higher. Among them – the iPhone 6s and 6s Plus, and iPhone SE.
Recall that iOS 11 will be available for installation on Apple devices this autumn. Now to see the new features only participants in the testing program. To become such a party can be anyone, but the stability of iOS is not guaranteed.
