According to comparative reviews on the web, the differences between the iPhone 14 and iPhone 13 are mainly reflected in some hardware upgrades and feature improvements. Whether or not it's "better to buy 13" depends on your need for new features and budget considerations.
The iPhone 14 series has improvements in terms of camera, processor, battery life, etc., but for some users, these upgrades may not be enough to justify the additional cost. For example, if your main focus is on basic features and app usage, rather than photography or using the latest technology, the iPhone 13 is still a very strong option and could be a better deal.
However, if you're particularly interested in photography or want to experience the latest technological improvements, such as a better camera system, longer battery life, and more processing power, then investing in the iPhone 14 series may be worth it.
Therefore, decisions should be based on individual needs and preferences. It is advisable to carefully compare the specifications and features of the two phones and consider whether it is worth paying extra for the new features. For users who are looking for the latest technology and features, the iPhone 14 may be a suitable choice. For those looking for value for money and meeting basic needs, the iPhone 13 may still be a very powerful and less costly option.
