Using an iPhone 5s without security updates

Hello. I know this is not a strictly hardware related issue but I would appreciate any thoughts. I am considering whether to upgrade to a new phone for security reasons. Currently I have an iPhone 5s with a very degraded battery but other than that it is functionally fine and am perfectly happy with the performance. However from what I’ve read it’s not a good idea to use any iPhone beyond five years after production ended given that Apple stop releasing security updates, meaning 2021 for the 5s. I am slightly sceptical that this risk is exaggerated and that as long as I am reasonably careful - avoid downloading any dodgy apps or visiting certain websites - then there is no real problem and can safely fit another battery to use for years. So for a complete novice, would you say the risk of using a phone without security updates is legitimate and should go ahead and get a new model or stick with the 5s? Thanks

The problem with out-of-date software is that you are by definition defenseless. All possible exploits have been announced publicly and depending on the exploit, it can be implemented silently. You have no way of defending or even knowing of any attacks taking place.

I get there is a vulnerability there but I am wondering if this is actually commonly exploited or whether the risk is so minimal it's not worth upgrading. I've definitely read plenty of articles that you should get a new phone because of security risks but whether this actually happens I don't know.
