Samsung Galaxy M15 used and refurbished

The Galaxy M15 5G is a phone you rarely need to plug in. It has a 6000 mAh battery, and with light use – messaging apps, email, maps, a few videos – it often still has enough power left for the next day. The Super AMOLED screen measures 6.5 inches with a 90 Hz refresh rate, and the phone supports 5G. Samsung put it on sale in spring 2024.

At SWOPiFY you'll find used and refurbished Samsung Galaxy M15 5G phones in the 128 GB version, in navy, blue and grey. Before a unit is listed, SWOPiFY partners run technical checks on it, and if something isn't working right, they repair it first.

What can the Galaxy M15 5G do?

The screen has Full HD+ resolution, so text and photos are sharp, and AMOLED gives you deep blacks and rich colours. In high brightness mode the panel reaches 800 nits, which helps you read a map or a message in full sun. Sound comes from a single speaker – enough for a podcast or a speakerphone call, but for films you're better off with headphones.

The body combines a glass front with a plastic back and frame. The phone weighs 217 g and is 9.3 mm thick, so you can feel it in your hand and in your pocket. The fingerprint reader is built into the side power button and unlocks the screen the moment you pick up the phone. NFC support for contactless payments depends on the market version, so check the specs of the specific unit before you buy.

Processor, cameras and battery

Performance comes from the 6 nm MediaTek Dimensity 6100+, backed by 4 GB of RAM. It's a set-up for everyday tasks: WhatsApp, the browser, YouTube, navigation and your banking app run smoothly, but with a dozen or more apps open, some of them will reload when you go back to them. Simple games run without problems, demanding titles only on low settings. On the back there's a 50 MP main camera with autofocus, next to a 5 MP ultra-wide and a 2 MP macro. Selfies are taken with a 13 MP camera, and video recording tops out at Full HD.

The 6000 mAh battery is this phone's strongest side. Wired charging goes up to 25 W, but with a battery this big a full charge still takes a while. There's no wireless charging.

What should you check before buying?

The Galaxy M15 5G has a 3.5 mm headphone jack, so you can plug in wired headphones without an adapter. The memory card situation is less good: the microSD card goes into the same tray as the second SIM, so you have to choose one or the other. To use the full 25 W, you need a USB-C charger compatible with Samsung fast charging (USB PD with PPS).

Updates are in good shape. Samsung promised this model four major Android updates and five years of security patches. The phone launched with Android 14, got Android 16 with One UI 8 in autumn 2025, and as of October 2026 it's still on the list of models receiving quarterly security patches. So you can safely use your banking app and payments on it. The main difference from its twin, the Galaxy A15 5G, is the battery – 1000 mAh bigger.

You can filter Galaxy M15 5G listings by:

• storage – 128 GB;
• RAM – 4 GB;
• colour – navy, blue or grey;
• price range;
• condition.

Every version has 128 GB, so the choice comes down to colour and condition. If you use two numbers and take lots of photos, turn on automatic cloud backup – a microSD card would take the second SIM's place.

What does the technical check involve?

Before a Galaxy M15 5G goes on sale as refurbished, it goes through a 44-point checklist, including:

• AMOLED screen – touch, brightness, dead pixels and signs of burn-in;
• battery – cell health and physical condition;
• the three rear cameras and the selfie camera;
• the fingerprint reader in the power button;
• connectivity – 5G, Wi-Fi, Bluetooth, GPS and NFC on versions that have it;
• SIM and microSD card detection;
• speaker, microphones, USB-C port and headphone jack.

Can you trust a refurbished Galaxy M15 5G?

A refurbished Samsung Galaxy M15 5G from SWOPiFY is a phone with a past: used, inspected by SWOPiFY partners and repaired if it needed it. We don't call it new and we never present it that way.

Every purchase is covered by a warranty. The condition grade tells you about the looks and the battery: Premium, Excellent, Good or Fair. If the phone is meant to last you for years, choose a higher grade – a healthier battery will make the most of those 6000 mAh.
