Editor's Review
The standard Facebook app has grown into a heavy piece of software: hundreds of megabytes installed, constant background activity, and a data appetite that punishes a metered connection. Facebook Lite is the answer to that, and a billion-plus installs show how large the audience for the answer turned out to be.
Same network, much smaller client. The feed, profiles, messages, groups, notifications, photo upload and marketplace access are all present in a simplified interface that loads on 2G and 3G, and the install footprint is a fraction of the full app's. On an older or cheaper Android phone the difference is not subtle, because Lite stays usable on hardware where the standard version stutters.
What you give up is polish and edge features. Video is downgraded, some interface elements and newer additions arrive late or never, and the design is plainly functional rather than pleasant. Meta has also restricted availability in certain markets at times, and messaging behaviour has shifted between builds, which is worth knowing before you make it your only chat client. The Teen content rating reflects a social feed with no meaningful filtering.
For anyone on limited data, limited storage or ageing hardware, the trade is a good one. For anyone with a current phone and an unmetered connection, there is much less reason to choose it.

Questions people ask
How is it different from the standard Facebook app?
Same account and same network, smaller client. Lite drops higher-quality media, some newer additions and much of the visual polish in exchange for a far smaller footprint and much lower data use.
Can I run both apps at once?
Yes, both can be installed and signed in to the same account, although running the pair means duplicated notifications unless you switch them off in one of them.
