Design
- Super compact and light
- Excellent phone for one-handed use
- Excellent build quality
- With the small screen, the on-screen keyboard is smaller too, and might be difficult to adjust to, if you are moving from a larger phone to this
Display
- Beautiful, glamorous screen with wide viewing angles, superb sunlight legibility
Software
- The intuitive, efficient and reliable software experience of iOS
- Misses out on some minor iPhone 6s features, like 3D Touch
- With the small screen, this is not the best phone for video watching, or web browsing experiences
- Only 16GB of memory may become limiting if you tend to install a lot of apps/games, or store a lot of videos on your phone
Performance
- Excellent, top-shelf performance and reliability across the board
Camera
- Just like the iPhone 6S, the primary camera is superlative, and among the very best cameras put on a phone
- The front camera is underwhelming at just 1.2MP
Audio
- Comes with best-in-class earphones
- Loudspeaker is not deep enough
Battery
- Excellent battery life (better than any other iPhone to date)
More
- Packs nearly every worthwhile feature (processor, great camera, always-on Siri) from iPhone 6S into a smaller, much more compact 4-inch phone - this a great choice for Apple fans who like smaller phones
- Currently this is a phone in a class of its own: there is no other phone of such size that's even remotely as powerful
- The iPhone SE works with all the old iPhone 5/5S cases and accessories, too
