After launching in 2015 with free unlimited storage and marketing the service around that key feature, Google Photos has become a popular option even for Apple users. However, that’s changing as the company announced last fall that the free unlimited storage is ending on June 1.
Instead of free unlimited storage, a 15GB limit will apply to photos and videos added from June 1, 2021. So your content that’s been previously added will remain safe. However, this will probably make some Apple users reconsider their photo strategy and take a look at the Apple One bundles.
