Using Google Photos to Backup and Store iPhone Pictures (for Free!)

I use iCloud to back up my iPhone, including my photos and videos, but I have also starting using Google Photos.  I used Picasa when it was active, so I have some Google Photos already, and I used to have an Android (RIP, my HTC) so I have a lot of Google Photos from those days.

After installing the Google Photos app, I went into settings (the three lines on the top left) and choose Back up & sync.  

I made sure my photos were set to auto-backup at the free storage quality.  Google started saving my photos, and whenever I check it, I see a nice collection of my recent photos and screenshots.  I don't know how the photos will print, but I back up my photos at full-size to my computer and this Google Photos option is free.  We all know that free is good.
​
There is a setting called "Free Up Space", which will remove photos that have been backed up.  I plan to use this when I am low on phone storage, which  happens frequently.     I am leaving the "Limit cache size" option off, because I like seeing the little thumbnails, but for someone who had a lot of photo storage space issues, limiting the cache might be a good options.
