If you plug the battery into a MacBook, iMac, or iPad (Air or Pro), the update can take just a few minutes.  

Yes I confirm this worked, I had two to do. I noticed that if the battery was at 100% and I plugged it into my laptop which is a MacBook Pro with a USB within five or 10 minutes it was updated when I put my phone on to verify. When my battery was completely dead it would not upgrade manually for a while. So I plugged it in to the wall got to 100% then quickly plugged it into my laptop this morning had a cup of coffee and then it was done. Last night girlfriends phone was at 59% and we put the new updated battery on and it charged it faster than normal and didn’t get too hot.
