The iPhone 6s is a great option for anyone who is looking to buy a smart phone. I can vouch for the product because I own one and I'm also a long time user of Apple's iPhone series. The phone is easy to operate and doesn't take much time adapt to its functions as a new user.
To start off I must say that the phone's design is sleek, rounded, and smooth. The back of is covered with a space grey aluminum backing that wraps around connecting to the screen. The phone is quite thin and the buttons protrude slightly from the edges. When you unlock the phone the screen illuminates and allows you to see the amazing resolution it has. It feels dense and is compacted because it is heavier than someone would assume by looking at it.
I was super excited to receive my new 64GB iPhone 6s on it's release date. I ordered it from my carrier and waited anxiously for its arrival. My previous phone was an iPhone 6, so I was a little concerned that upgrading might feel like getting the same phone all over again. However, I was using a 16GB model on the iPhone 6 and needed extra storage, so I decided to go ahead and upgrade to the 6s at release. After using the phone for 24 hours, I'm glad I did. Here's why:
COLOR: I LOVE the new rose gold color! It looks a lot like copper, and it is really fun to have a new iPhone color. It also perfectly matches my rose gold Apple Watch. For those who are concerned that it is too pink, well, it is pinkish, but It really seems more coppery to me.
CAMERA: The camera upgrade is very nice. I especially appreciate the new flash feature for the front facing camera. I tested it last night against the iPhone 6 and it had substantially better performance in low-light conditions. I also like the live picture capacity. Yes, its a bit gimmicky, but it is pretty neat to have animated pictures.
3D TOUCH: I like the 3D touch capacity. It is nice to be able to access shortcuts just by pressing deeply on certain apps. Though it is not currently used by many developers, I think this has a great capacity for future growth, and I look forward to seeing what developers will do with this capacity.
SPEED: This phone is FAST! I was already impressed by Touch ID on my iPhone 6, but the 6S is incredible. Literally, you touch the sensor for just a moment and the screen unlocks. I also tested the connection speed on my home WiFi and found that the 6S generally achieved 8-9 MBPS faster connections than my 6. I think the improved processor and 2GB RAM are making a difference in performance in a very positive way.
Overall, I'm happy I upgraded. The 6S is speedy and has some cool new features. I was also able to gain more storage by getting the 64GB model. For those considering purchasing it, I do recommend it. However, if you have a iPhone 6, you will probably be fine waiting until the 7 is released. For those with 5S's or below, I feel this is a worthwhile update.
This phone is fast! It is responsive, and the scroll and swipe is so fluid it makes other iPhones seem sluggish and slow. This is the fastest, toughest iPhone made to date as well. Not only does it have a better, more durable screen, but it also has a much tougher enclosure which will not scuff or dent like the previous models. If you were on the fence about this phone, I hope I was able to help you make a decision... get the warranty to be on the safe side!
Also, I'm with Sprint. Sprint customers who get the 6s, are automatically enrolled in iPhone Forever, which means that when the iPhone 7, 8, 9... comes out, we get them immediately, for free; all we have to do is go to the Sprint Store, hand them our iPhone and they hand us the newest release right then and there! With a phone this expensive and in demand, iPhone Forever is a no brainer!
My final piece of advice: Be sure to get at least the 64GB model to ensure you have enough storage. With the newly released live photos and 4K video, it will be very difficult to maintain sufficient storage on the 16GB base model.
