iPhone sw

Today I found in the wastebasket of my Macbook a big piece of software "iPhone_5.5_P3_15.3_19D50_Restore.ipsw" (its size is 5,97 Gb). Searching internet I found a few pieces of news and I presume it is an outcome of a firmware upgrade of my iPhone 7 plus.

However I read that usually this kind of upgrades are on demand (no automatic upgrade). Moreover I presume that this upgrade should have happened while my iPhone was connected for a while through an USB cable, not just wirelessly, with my macbook. If I am right, that is awkward because my iPhone was phisically connected with Macbook a few days ago, but I found the .ipsw file today only .

Can anybody explain to me what's happened or is happenig?

And -last but not least- can I safely remove the .ipsw file I found in my basket or am I to save it for any future use?

Thank you very much.

If you look at your phone in Settings, General, About you will find Software Version.

It should read 15.3.1 (19D52) . If that is the case then the 19D50 is an older version which is of no use to you as it is no longer signed. In any case it is already in the waste bucket.

It was placed on your disk while updating the iPhone using the Mac, and allows you to "try again" after a fail without having to re-download the 5GB. Automatic purging pushed it to the waste basket and you can empty it without problems.
