I've had my iPhone 6S in about two weeks, and I love it. The predecessor was an iPhone 5, and it was really lethargic after over two years of use, with information on the way from my 3GS and then 4. This time, I put the phone as new.
The first thing I want to point out is the fingerprint reader, the damn thing! Only it does upgrade warranted. It reads quickly and is almost always right, unless you are really dirty. This allows one to save huge time by not having to enter the code every time.
Then we have the 3D Touch. A brilliant idea, and the performance is not bad either. Works very well and opens up a whole new dimension of use, very smooth when it is available. Unfortunately, it is not very much implemented, but it will guarantee that emerge updates using the 3D Touch when the respective developers have found a way to use it.
Battery life is very good, enough always morning to evening, and the economical use can add to it to two days. Siri has developed since I tested her last, and now is the hen bisexual. My Siri is obviously a man from Australia, the best accent.
Close button moved from the top of the phone to the right side, about 2 cm bottom. Felt very stupid and unnecessary at first, but you get used to it quickly, and it is now easier to reach, and it is less cumbersome to take screenshots.
Flash has both front and rear, and both of them have done its done in my opinion.
Edit; I've had it for a year soon, and it is still grim. Do not understand how you have fared without the 3D Touch before.
Kanonbra phone. No doubt! But they are getting good expensive ...
