I refuse to update my iPhone 7 to iOS 11 for that reason.
Same with my MacBook 10 inch. I refuse to update to any new OS because the laptop hardware won't be able to handle it. It will be laggy and slow, forcing you to buy a new laptop. It's sickening what they do. I don't play that game anymore. I've learned from past mistakes.... ALWAYS stick to only the OS the device came with.
Must be the Ipad Mini 2 (latest is 4), which was the first mini to come with a 64-bit processor, which is a prerequisite to iOS 11. Our Mini 1 is 32-bit and is stuck with iOS 9.X.X. I can't imagine asking it to do much more, because it's not very fast as-is; however, it plays the learning games and videos pretty well for our son and came to us for $free.99, so we can't complain.
I updated my iPhone 6-Plus to iOS 11 (now on 11.1) and have no complaints. I experienced some lag at first and there are instances when screen changes take a fraction of a second longer, but the benefits of the new OS are worth it to me. Your 7 is even more powerful and capable, and will benefit from even more features than my phone.
