What is a disadvantage of updating your OS?

A couple disadvantages of updating your OS is: you cannot use your device while it is updating, which can take a while, and if you have an older device that still supports newer updates, it can slow down the machine. Another disadvantage is when the developer releases the OS, it can be buggy at first and cause you to lose out on performance and/or battery life. The last one is that in rare cases, your computer can suffer extreme data loss during the install process if it goes wrong.
