iPhone 7 Plus features Dual 12MP cameras for high-resolution zoom and an ƒ/1.8 aperture for great low-light photos and 4K video. Optical image stabilization. A 5.5-inch Retina HD display with wide color and 3D Touch. An A10 Fusion chip for up to 2x faster performance than iPhone 6. Touch ID. Faster LTE. The longest battery life in an iPhone. Immersive stereo sound, splash and water resistant, and iOS 10.
Camera is the main selling point but to me the storage is much better. Going from 16 gb to 32 gb has been a blessing. I can finally store music again! This is great if you dont have spotify premium or other offline access to music. My gym has bad wifi and signal so this change is most welcomed. Speed is much better as well especially the fingerprint reader. Only difference is the headphone jack but i use bluetooth anyway
