If you don't have much access to Wi-Fi during the day, you're probably using a lot of data to back up your photos on Google Photos. All of these photos are stored in full resolution, which means that if you're limited in data usage, you definitely don't want to spend most of it loading these bulky images.
Fortunately, Google Photos has come up with a new way to reduce your data usage. Soon, thanks to a feature called Backup Express, you can upload images at higher speeds and consume less data on Google Photos.
Google Photos Product Manager Raja Ayagari has released a report today stating that the Express Backup feature can load images faster than normal in the app by compressing images. In this case, images are compressed to 3MP format and videos are compressed according to a standard pattern. However, you will also have options for storing high quality images or original resolution.
But another useful feature of Google Photos is the ability to set data consumption limits. Thanks to the new app settings, you can consider the daily backup limit on the app from five megabytes to infinity.
According to Google, these new features will initially be released for users living in India, but will gradually become available to users in other countries as well.Source
