Facing a used Galaxy S23 and S24, it is tempting to ask only which is newer. Two used phones cannot be ranked by launch year alone: storage variant, market origin, battery condition and repairs shape the experience. Start with the exact TECHBUY units on offer and decide whether the S24 adds something you will use.
Does the slightly larger S24 feel different?
Samsung comparison data puts the standard S23 at 6.1 inches Full HD+ and the S24 at 6.2 inches Full HD+. Both remain relatively compact beside Plus or Ultra phones. A 0.1-inch difference cannot tell you which suits your hand, especially inside a case. Hold both, type one-handed and read a small-text webpage at your normal brightness.
Samsung describes a 1-120Hz refresh range for S24 and 48-120Hz for S23 in its comparison. That does not guarantee a dramatic visible difference in every task. On a used phone, inspect dead pixels, uneven colour, brightness and touch before focusing on refresh-rate figures.
Similar camera numbers, market-specific processor
Samsung lists a 50MP main, 12MP ultra-wide and 10MP telephoto rear camera for both base models. S24 brings a later processing and software generation, but equal megapixels cannot prove equal or unequal image quality. Photograph a person, a dim scene and a distant subject on the actual units; check colour, focus and lens glass.
TECHBUY describes its S23 as Snapdragon 8 Gen 2 for Galaxy and its S24 as Exynos 2400. The S24 processor varies by sales market; do not apply a foreign review configuration to the phone in front of you. Confirm model number, system information and warranty records.
Compare battery and capacity fairly
Samsung rates the original S23 battery at 3,900mAh and S24 at 4,000mAh. A 100mAh design difference cannot predict runtime on used units. Ask about battery health, replacement history, heat during video or mobile-data use and charging with a suitable accessory.
TECHBUY currently lists S23 at 128GB or 256GB and S24 at 256GB or 512GB. Compare similar capacities and check free space. For someone recording a lot of video, storage may be more useful than paying only for a newer model year.
A short checklist before paying
Test display, fingerprint unlock, front and rear cameras, speakers, microphone, Wi-Fi, cellular signal and charging port. Look for dents or prior repairs, and confirm that the previous owner account is removed. Match serial/IMEI, storage, colour and written warranty to the order.
Lean toward S24 when its slightly larger screen, available storage and unit condition suit you. Lean toward S23 when the right variant costs less and passes inspection. Do not pay for a newer generation while ignoring a weak battery or an undocumented replacement screen.

AlternativeConclusion
Galaxy S24 has measurable changes from S23, but a used purchase rests on the individual device. Hold both, compare the correct chip and storage for the sales market, test photos and inspect battery, display, account status and warranty. A sound older phone can make more sense than a tired newer one.
