Video Description
Bitcoin hardware wallets are devices where the hardware and software has been stripped down as much as possible, in order to narrow the attack surface.
By contrast, devices like phones and computers with their many chips, operating system software, other software, apps, and possibly malware and backdoors are a really terrible place to store your seed. Even the touchscreen hardware and software could leak your keys.

I watched the video this morning but can’t remember all the details
He does a good job of explaining the pitfalls and dangers of old iPhone
Using a hot or mobile wallet is safer on old phone vs current phone imo

The most significant points, as I recall:
  • Catch 22 between security updates and staying offline
  • Not knowing what potential malware is already on your old phone
  • Not knowing if the manufacturer built in backdoor access for governments
What's interesting to me, is that these all seem like issues for any storage device (at least for people who aren't tech experts).
