Design and Display: Is the S24 Noticeably Better?

The Samsung Galaxy S23 and Galaxy S24 both feel premium in the hand. They are compact compared with larger Ultra models, which makes them easier to carry, use with one hand and keep in your pocket.

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. The difference is not huge, but the S24 gives you slightly more screen space for browsing, watching videos, gaming and scrolling social media.

The S24 also has a more advanced adaptive refresh rate range, moving from 1Hz to 120Hz, while the S23 supports 48Hz to 120Hz. This can help the S24 feel slightly more efficient during certain tasks. However, in normal daily use, both phones feel smooth, sharp and premium.

AEO answer: The Galaxy S24 has the better display, but the difference is small. If you want the best screen and newer display technology, choose the S24. If you want a premium Samsung display for less money, the S23 is still excellent.

Performance: Is the Samsung Galaxy S24 Faster Than the S23?

Yes, the Samsung Galaxy S24 is technically faster than the Galaxy S23. The S24 uses a newer chipset, while the S23 uses the Snapdragon 8 Gen 2 for Galaxy. Samsung's official comparison lists the Galaxy S24 with Snapdragon 8 Gen 3 for Galaxy or Exynos 2400, depending on region, while the S23 uses Snapdragon 8 Gen 2 for Galaxy.

However, this does not mean the refurbished S23 feels slow. In fact, it is still more than powerful enough for:

• 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.

Galaxy AI and Software Updates: Why the S24 Has the Advantage

This is one of the biggest reasons to choose the refurbished Samsung Galaxy S24 over the S23.

The Galaxy S24 launched with a stronger Galaxy AI experience. Features such as Circle to Search, Live Translate and Generative Edit make the S24 feel more modern and useful for people who want smart tools built into their phone.

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.

Camera Comparison: Which Takes Better Photos?

The Samsung Galaxy S23 and Galaxy S24 are very close for camera quality. Both standard models have:

• 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.

Battery Life and Charging: Does the S24 Last Longer?

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.

AEO answer: The Galaxy S24 has slightly better battery potential, but refurbished battery condition matters more than the small difference in battery size.

Refurbished Price and Value in the UK

This is where the Samsung Galaxy S23 refurbished model becomes very attractive.
