A new Google offline Search feature is now rolling out for Android users. After this update, you will able to perform searches even when your device is offline.
With this new feature, the app will remember your search queries for when it cannot connect to the internet. As soon as you get into a network, it silently runs that query again for you and shows a notification with the results. Google says this feature doesn’t require any additional battery or data than performing a normal search.
Google official post,
Mobile networks can sometimes be inconsistent or spotty, which means that even if you have a connection when you start your search, it might fail before you get your results back. With this change, search results are saved as soon as they are retrieved, even if you lose connection afterward or go into airplane mode. So the next time you lose service, feel free to queue up your searches, put your phone away and carry on with your day. The Google app will work behind-the-scenes to detect when a connection is available again and deliver your search results once completed.
This should feature will be helpful for users with low connectivity or for someone who is traveling.
