It was the original battery and iOS was saying 90% capacity. I had been watching the capacity since it was added to iOS and originally intended to swap it out with Apple for the $30 (or just replace it myself, like I have for previous iPhones). I really think if that's the only concern, replacing the battery has always been a huge cost/benefit most people don't seem to think about.
The 6s has a 1715 mA·h battery versus the Xs' 2658 mA·h. This is why still including the 5w charger is silly. Charging with this was already slow on the 6s. It's really hard to quantify usage, especially when the chips are so different. I really noticed the battery life start dipping when I switched to Bluetooth headphones when using the 6s. I'm hoping on the Xs either that Bluetooth is more optimized, but even if it isn't the same draw will drain a smaller percentage of the battery.
The main thing I was hoping to capture in my reply was the little, less concrete things about the update. I usually skip a few generations and a lot of the game changers are small, personal things that don't always jump out in reviews. As an old example, I don't often use AirDrop, but when I finally updated all of my devices to support it, it's way easier than messing with Dropbox, using some app with a web server, connecting a cable, or using a usb or memory stick. Other times it's better radios that power on more quickly, are faster, or more reliable.
