- It's super fast. I have my 4S upstairs in my bedroom and have been using it to listen to music periodically. It is surprising how slow the phone had become. I didn't even realize how slow it was until getting a new one. Everything from launching apps to switching between apps to browsing the web is faster.
- The screen is bigger, which is great for consuming content. I find myself using the browser more and reading more news and Twitter feeds on the newer phone, I think simply because it is easier to read the text. Additionally, I was concerned the bigger size would be bothersome in my pockets but it really isn't.
- The bigger screen makes navigating more difficult. The two-button tap to bring the screen down towards the bottom is a great idea, but still not as convenient as being able to navigate all of the buttons with my thumb without having to change my hand position. This is the biggest difference that I've had to get used to, and I'm still not completely used to it.
- The volume buttons are directly across from the lock screen button, so frequently when I'm trying to adjust the volume, I hit the lock screen button, or vice-a-versa.
- The touch ID works great, but sometimes it works a little too well. It's nearly impossible to just see the home screen without completely logging in.
Overall the 6S has been a good upgrade for me, and probably necessary. I can see how some people think the 5S is the best iPhone to date. The screen is a little smaller for easy one hand navigation, while still being large enough to consume content. Despite its drawbacks, the 6S is a better phone than the 4S, but not perfect.
