Twitter says that the service also minimizes data usage and is resilient on unreliable and congested mobile networks, also supporting an offline mode. You also have the option of further reducing data usage by only downloading low-res previews of images and videos …
We have added a data saver mode, which further reduces the amount of mobile data used. In this mode, you will see a preview of images and videos before choosing which ones to fully load. This can reduce your data usage by up to 70%, making it more affordable for you to use Twitter in areas where mobile data is expensive.
In this mode, you get a blurred version of images and can tap them to download the full image.
The mobile app supports all the main features of the service, including direct messages, trends and profiles.
Twitter Lite is primarily aimed at emerging markets across Asia, Latin America and Africa, but is available worldwide. It currently supports 42 different languages.
