Usually this is the case when there is not enough storage to install the update. How much free storage space to you have on your iPhone 6s? Below are other requirements that your iPhone must meet to complete the update:

Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version-

Your iPhone must have a fast Wi-Fi connection; you cannot update over cellular data or a cellular hotspot
The iPhone can not be in Low Power mode
The battery state of charge must be above 50%
Your iPhone must have at least 6GB or more free storage space
Your iPhone cannot be connected through VPN
You should leave the phone plugged in until it finishes updating, both to assure that it remains above 50% and to keep Wi-Fi enabled (Wi-Fi turns off when the phone sleeps if not connected to power).
