I haven't updated my iPhone and keep getting messages to update it.
What are the upsides and downsides of the update and how long does it take please?
Thanks in advance

It takes about 5 minutes to update my iPhone and iPad. I've owned iPhones for years and have personally never had any issues. But some updates have had problems for a minority of users - Google the latest update to find out if there are any known issues. As a rule of thumb, I always leave it a couple of weeks after first getting the prompt to update. This is normally long enough for Apple to identify and fix any issues with the update.
