I switched to Google Photos after using iCloud for 5 years and I'm never going back

If your iPhone storage is full and your iCloud won't back up because that's also full, Google Photos can help you free up space on your phone. Unlike iCloud, Google Photos offers free unlimited storage of compressed photos and videos. iCloud users who are running out of storage space on their iPhone can use Google Photos to free up a lot of space. Business Insider's A.C. Fowler tried Google Photos after using iCloud for five years and it allowed him to finally free up space on his 16GB iPhone 6s.
