The iPhone 6S is Apple's latest smartphone. It was announced and launched in October 2015. It is a direct successor to the iPhone 6, and comes with three major new features: 3D Touch, a much more powerful camera, and a faster processor. It comes with numerous other improvements too which are discussed separately.

3D Touch add two more touch controls to the iPhone. In addition to a standard press, there's a harder press call 'Peek' which allows to preview items such as messages, photos, etc. without fully opening them. If you decide to open the previewed item, you can press even harder to 'Pop' the item into its proper view. It is used in stock apps, and is being slowly incorporated into third-party apps.

The camera has received a nice bump. It has a 12 megapixel sensor that takes more detailed photos, and allows for 4K video recording. Slow-mo videos can now be record at Full HD 1080p 240fps instead of HD 720p 240fps on the iPhone 6. Another neat feature called 'Live Photos' captures 1.5 seconds of video before and after your still image, which gives you greater context of every photo you take.

The faster processor (Apple A9 chip) is also more efficient, resulting in a slight increase in battery life. It comes with the M9 motion coprocessor that allows you to use "Hey Siri" feature without charging the phone. Touch ID has also received a boost, and is now twice as fast.

The iPhone 6S is also water-resistant. Apple hasn't marketed this feature, but several tests suggest it can be submerged in shallow water for short periods of time without any damage. It isn't recommended you do this on purpose, but it is still nice to know it can take the accidental water spill!

All in all, the iPhone 6S is a great improvement over the previous iPhone in every single way. It makes for an altogether smoother user experience, that is recommended for every iPhone user who can afford to upgrade. The Rose Gold color looks really nice, by the way. I would get that, despite the suspicions it may generate on my masculinity.
