It is difficult to predict exactly what the best features of mobile phones in 2023 will be, as technology is constantly evolving. However, some features that are likely to continue to improve in the coming years include: 

• Camera technology: Mobile phone cameras are becoming increasingly advanced, with better resolution, more advanced sensors, and improved low-light performance. In 2023, we may see even more advanced cameras, with features such as 8K video recording, larger sensors, and more advanced software for image processing. 

• Battery life: As mobile phones become more powerful, the demand for longer battery life will also increase. In 2023, we may see mobile phones with even larger batteries, or with more advanced power management systems that can extend the battery life of the device. 

• Display technology: Displays are becoming larger and more advanced, with higher resolutions and better color accuracy. In 2023, we may see even more advanced displays, such as foldable or rollable screens, or displays that can be used with virtual and augmented reality devices.

 • 5G Connectivity: 5G networks are becoming more widely available, and will be more prevalent in 2023, providing faster internet speeds, better connectivity and low latency. 

• Artificial Intelligence and Machine Learning: AI and Machine learning will be more prevalent in 2023, enabling more advanced features such as predictive text input, facial recognition, and more sophisticated virtual assistants. 

Please keep in mind that these are predictions based on current trends and not a guaranteed feature of the mobile phones that will come out in 2023.
