@ZMAHD is correct! The S23+ comes with a larger battery, and starts with 256GB of internal storage, the second being 512GB. The screen is also larger (6.1" vs. 6.6").
As a user, I can tell you that the main difference between the S23 and S23+ is the size and specs. The S23+ is the larger model with better specifications and a larger screen, while the S23 is a more compact and budget-friendly option. Both phones run on the latest Android operating system and can be used with the S23+ apk for enhanced features and customization. However, the S23+ will likely offer a more premium experience with its advanced specs and features. It really comes down to your personal preference and needs, so make sure to consider your priorities before making a decision.
