iPhone
The iPhone 7 represents a big update, no doubt about it. Apple introduced an amazing dual-camera setup in the Plus model, which allows for 2x optical zoom and on-the-fly depth-of-field effects.
Both sizes feature the improved A10 Fusion chip, a redesigned Home button with haptic feedback, better battery life, Lightning Ear Pods, and storage ranging from 32GB to 256GB.
The iPhone 6s and 6s Plus are still available, and are great devices in their own right. With 3D Touch giving you a greater range of interactions with apps, plus a 12MP rear camera with 4K video recording and Live Photos, consider them if the iPhone 7 is too expensive.
And let’s not forget the iPhone SE. Though it lacks 3D Touch, it packs in many of the 6s’s features, such as the A9 chip and M9 motion coprocessor, and has a more compact 4-inch screen.
