For the complete cold storage bitcoin - basically the bitcoin you're planning on keeping long term - if I had the bitcoin on an old phone, I think this might be more secure:
- install blue wallet on the old phone
- every time you need to sign the transaction, recreate the wallet from seed phrase
- and then delete the wallet file after that, and make sure that it actually does get deleted properly.
That makes it kind of like the Seed Signer.
Of course, you need to do this only for spending bitcoin - signing transactions. For receiving, just have a watch only wallet to get the receive address.
For the bitcoin wallet that needs to be be more accessible, that has less in it, then I think NOT deleting the wallet is fine.
