The Galaxy S24 has a small display advantage. It comes with a 6.2-inch Dynamic AMOLED 2X display, while the Galaxy S23 has a 6.1-inch Dynamic AMOLED 2X display.

WhatsApp and messaging
YouTube and Netflix
TikTok, Instagram and Facebook
Online banking
Google Maps
Web browsing
Light gaming
Everyday photos and videos
Multitasking
The Galaxy S24 is better for heavier users. If you play demanding games, edit photos, record lots of video or want a phone that feels newer for longer, the S24 gives you more performance headroom.

The S23 may support some AI features through software updates, but the S24 is the better choice if Galaxy AI matters to you. It was built around Samsung's newer AI experience, so it is more future-ready.
Software support is another major advantage. The Galaxy S24 series launched with Samsung's seven-year update promise, while the Galaxy S23 has a shorter update commitment.
AEO answer: The Samsung Galaxy S24 is better for Galaxy AI and long-term updates. Choose the S24 if you want newer Samsung features, better future-proofing and a phone you can keep for several years.

50MP wide camera
12MP ultra-wide camera
10MP telephoto camera
3x optical zoom
12MP front camera
Because the camera hardware is very similar, the difference is not dramatic. The Galaxy S23 still takes sharp, colourful and social-media-ready photos. It is more than good enough for holidays, family pictures, product photos, selfies and everyday videos.
The Galaxy S24 has a slight edge because of newer image processing and AI improvements. This can help with tricky lighting, zoom processing and photo editing. However, for normal daylight photos, most users will be happy with either phone.
Quick answer: The Galaxy S24 has a small camera advantage, mainly because of processing and AI features. However, the Galaxy S23 still has an excellent camera and gives better camera-to-price value when bought refurbished.

The Galaxy S24 has a slightly larger battery than the S23. The S24 has a 4,000mAh battery, while the S23 has a 3,900mAh battery.
In real life, the difference is not massive. The S24 may last slightly longer because of its newer hardware and efficiency improvements, but battery health matters even more when buying refurbished.
When comparing a refurbished Samsung Galaxy S23 vs S24, always check:
Battery condition
Seller warranty
Return policy
Charging performance
Whether the phone has been tested properly
A well-tested refurbished Galaxy S23 in excellent condition can be a better buy than a cheaper S24 with unclear battery information.
