Best Practices for Mobile Syncing

I'm building a cross‑platform mobile app that needs to sync user data across devices. What are the key considerations to ensure data consistency, low latency, and minimal battery impact?

• Conflict resolution strategies
• Efficient background syncing
• Handling offline scenarios

Any real‑world examples or libraries you recommend?

For conflict resolution, I usually go with a last write wins approach combined with a version vector. It works well with Couchbase Lite and its sync gateway.

Consider using Firebase Realtime Database for real‑time sync. It automatically queues changes when offline and merges them when the device reconnects.
