Refurbished Galaxy S23 Green -128GB

The Galaxy S23 128GB still holds up well in 2026. The Snapdragon 8 Gen 2 chip was among the fastest when the phone launched, and it has aged better than many expected. Apps open quickly, multitasking is smooth, and the phone does not throttle under sustained load. The 6.1-inch Dynamic AMOLED display is genuinely good – colours are vivid without being overcooked, and outdoor readability is fine for a compact screen. Where the S23 stands out among refurbished Android options is Samsung software support. Samsung committed to four years of OS upgrades and five years of security patches for the full S23 range, so this is a device that stays current for quite a while. At 128GB, storage covers most users comfortably without constant space management. The compact form factor is also worth noting – the S23 fits in a jeans pocket where most larger phones simply do not.

The 50MP wide camera on the Galaxy S23 is one of the better sensors Samsung has fitted to its standard lineup. In decent light it produces detailed, accurate shots with natural colours. Dynamic range is handled well – skies and shadows hold detail rather than blowing out. Low-light performance is better than you might expect at this price point: Nightography processing pulls usable shots from darker scenes, though very low light still shows some grain. The 12MP wide keeps a consistent look with the main lens, which matters when switching between shots in a burst. The 10MP telephoto at 3x optical zoom is a practical focal length for portraits and mid-distance subjects. Video capture goes up to 8K on the main sensor, though 4K at 30fps remains the sweet spot for balancing file size and quality. The 12MP selfie camera handles calls and self-portraits without issue.

The 3900mAh battery in the Galaxy S23 is smaller than many Android competitors at the same screen size. In day-to-day use, that is rarely a real problem. The Snapdragon 8 Gen 2 is an efficient chip, the 6.1-inch display does not drain power at the same rate as a larger panel, and One UI has solid battery management built in. Most users will comfortably get through a full working day on a single charge with moderate use. Heavy users – streaming, navigation, gaming – may want to top up sometime mid-afternoon. Refurbished units sold here go through battery health checks before dispatch. If capacity has dropped significantly, the battery is replaced or the condition is clearly noted in the listing grade. With 25W wired charging, getting from flat to around 50% takes roughly 30 minutes, which is quick enough for a useful lunchtime top-up

Before buying any refurbished handset, a few checks are worth making. Start with the condition grade – it tells you exactly what to expect cosmetically. Grade A means minimal marks; lower grades may have visible scratches on the frame or back panel. Check whether the device is confirmed unlocked: this listing is fully unlocked and works across all UK networks without issue. Confirm that a warranty is included. Every Samsung Galaxy S23 sold here comes with a one-year warranty covering hardware faults under normal use. Look at the storage and RAM: this is the 128GB model with 8GB RAM, which suits most users well. Check the returns window – if something is not as described, you want a clear process to fall back on. Also worth checking: whether the software is up to date and whether the phone has been factory reset.
