With this change, search results are saved as soon as they are retrieved. Even if you lose connection afterwards or go into airplane mode. So, the next time you lose service, you can 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.
And, if you’re worried about data charges or preserving battery life, you don't have to. This feature won’t drain your battery. And, by fetching streamlined search results pages, it minimally impacts data usage.
