Source: Introducing Twitter Lite
Twitter Lite uses less data, loads faster on slower wireless connections and takes up less than a megabyte of memory on a device. The mobile web app loads up to 30 percent faster on a 3G device than the original mobile site, and Twitter claims it can save up to 70 percent of data. It also offers faster navigation to Twitter features like direct messages and notifications.
This version of Twitter is geared toward developing markets such as Asia Pacific, Latin America and Africa. While mobile users in developed markets have widespread access to fast 4G LTE networks, much of the world still only has access to 2G and 3G wireless service, which is considerably slower.
