What makes a crypto iOS wallet safe for high-value transactions?

I hate opening my desktop every time I want to swap or do a quick transfer.

So, I use a crypto wallet on my iPhone for regular transactions since it's convenient. When it comes to moving larger amounts, I'm not sure if it is the most secure way.

To approve large transfers, I use a separate laptop and a browser extension paired with a hardware wallet. This keeps my crypto activity separate from everyday browsing and reduces some of the security risks.

I know some crypto iOS wallets have security features like biometric authentication and hardware wallet pairing.

Still, I am not comfortable making high-value transfers from my phone. Mostly because it is my primary phone and I use it for everything.

I want to know how you guys approach mobile wallet security. Is using a hardware wallet with your primary phone secure enough? Or does having a separate phone make a difference?
