Conversations is designed to have a very low impact on battery life, ensuring prolonged usage without excessive battery drain. The application's compatibility with every XMPP server makes it a versatile communication tool for various users. The XMPP protocol's extensibility, through standardized extensions known as XEPs, allows Conversations to enhance the overall user experience. Conversations supports several XEPs to improve functionality and user experience.

The supported XEPs include XEP-0065 (SOCKS5 Bytestreams), which facilitates file transfers when both parties are behind a firewall. XEP-0163 (Personal Eventing Protocol) enables the use of avatars, enhancing personalization. XEP-0191 (Blocking command) allows users to blacklist spammers or block contacts without removing them from their roster, improving user control over communication. XEP-0198 (Stream Management) allows XMPP to withstand network outages and changes to the TCP connection. XEP-0280 (Message Carbons) automatically syncs messages to the desktop client. XEP-0237 (Roster Versioning) saves bandwidth. XEP-0313 (Message Archive Management) synchronizes message history. XEP-0352 (Client State Indication) lets the server know when Conversations is in the background. XEP-0363 (HTTP File Upload) allows you to share files in conferences. Conversations ensures that your communications remain private and secure, and provides a user-friendly way to communicate with other people who are also security-conscious. Conversations is a great choice for anybody who wants to make sure their communications stay private.
