I'm still waiting for my pre-order to arrive, although I am very excited. I'm currently upgrading from an iPhone 6 (64GB) to the iPhone 7 Plus (128 GB), so there will be plenty of new features. Earlier this year I dropped and shattered my iPhone 6 screen, so I had to get a 3rd party replacement since the frame of my iPhone was bent and Apple could not simply replace the screen, therefore my screen is kind of buckling and has light leaks and other weird issues. Here are the features I'm looking forward to in the new phone:
- jump from 64 GB to 128 GB of storage
- A8 to A10 Fusion chip (mine lags sometimes)
- 1GB to 3GB of RAM
- 4.7" to 5.5" Screen
- Wide Color Screen
- 326 ppi to 401 ppi
- 3D Touch
- Cool new home button
- 2nd Gen Taptic Engine
- Live photos
- jump from 8 MP to 12 MP Primary lens
- jump from 1.2 MP to 7 MP FaceTime HD Camera
- Image stabalization for front lens
- Retina Flash for Selfies
- Wide color capture on front and back lenses
- Quad-LED True Tone Flash
- jump from f/2.2 to f/1.8 on primary lens for Low light photos
- Telephoto lens for 2x zoom
- Double lenses for future depth mapping applications
- Bokeh effect coming later
- 4K Video recording
- Optical image stabilization
- "stereo" speakers
- Water resistance
- New black color
- 3x Stronger Aluminum compared to iPhone 6
- 1810 mAh to 2,900 mAh battery
- Better bluetooth, much faster LTE speeds
- 2nd generation Touch-ID
- support for W1 chip enabled devices
This to me seems to be a very large feature set. I understand that many people on the 6s may not see much improvements, but that's typically the case if you upgrade every year.
