As someone who values all-day battery life and the convenience of contactless payments, the Poco C40's advantages outweigh the A3x's incremental performance and software updates. The significantly larger battery and faster charging are hard to ignore, especially in the budget segment. Ultimately, the choice depends on individual priorities, but for my needs and usage patterns, the Poco C40 delivers greater overall value.
