usb nvme adapters are not expensive and it likely won't be the only time you need it. they are a handy accessory to have on hand if you have nvme storage.
don't mess around with imaging to a file on the zfs, then restoring it. simply clone nvme -> nvme using a usb nvme adapter then replace the internal with the clone.
my old phones (going back all the way to the 'real' nokias) went a full month between charges. the last two with 4g volte suck so much power, it is every 2-3 days now, including my current hmd-made nokia (only a couple weeks old) with same capacity battery as what's stated in the article for the 'new' one.
i had just looked that up on verizon here. you can configure it to be whatever you want (with some limits), and it's what gets sent with your phone number for caller id to compatible mobile devices/plans and to landlines with name & number caller id capability.
