The Samsung Galaxy S25 is in stock at Mascom International, priced at KSh 70,000 for a used unit with 256GB of storage, 12GB of RAM, the Snapdragon 8 Elite chip and a 4000mAh battery. Samsung launched it in February 2025, and this phone is a carefully maintained international import in clean used condition. Every Samsung Galaxy S25 runs the same Snapdragon 8 Elite worldwide, so you never have to guess which processor you are getting. The 6.2-inch 120Hz Dynamic AMOLED 2X screen sits in a 162g body that fits easily in one hand. Find it at Old Mutual Building, Kimathi Street, Nairobi CBD.
Built for journalists, doctors and developers across Kenya who want top-tier speed without a large phone, the Samsung Galaxy S25 handles fieldwork, ward rounds and remote coding sessions alike. Big phones are awkward to hold on a boda boda or in a packed matatu, while small phones usually cut corners. The Samsung Galaxy S25 keeps a 50MP main camera, a 3x telephoto and 12GB of RAM in a pocket-friendly size. Its 3nm chip runs Galaxy AI features such as Live Translate and Note Assist quickly, which helps when transcribing interviews, summarising long meetings or translating a call with a supplier abroad.
Where most Nairobi electronics shops price used S-series phones without testing them, Mascom International checks the screen, cameras, battery and network on every Samsung Galaxy S25 before sale, then backs it with a 6-month warranty. Buyers throughout Kenya report that the Samsung Galaxy S25 feels quicker day to day than older, bigger phones that cost more. Come and try it at our Kimathi Street store, or order on WhatsApp and pay only when the Samsung Galaxy S25 reaches you.
Common Questions About the Samsung Galaxy S25
How much does a used Samsung Galaxy S25 256GB cost in Kenya?
A used Samsung Galaxy S25 256GB with 12GB RAM costs KSh 70,000 at Mascom International, Kimathi Street, Nairobi. The price includes a tested phone, a 6-month Mascom International warranty and pay-on-arrival delivery across all 47 counties. A charger is not included, in line with Samsung's current packaging, so pair it with a 25W Samsung charger from our store. The used Samsung Galaxy S24 Plus 256GB costs KSh 5,000 less at KSh 65,000, and the used Samsung Galaxy S26 256GB costs KSh 18,000 more.
Is the Samsung Galaxy S25 worth KSh 17,000 more than the Samsung Galaxy S24 256GB?
For heavy users, yes. At Mascom International the used Samsung Galaxy S25 256GB costs KSh 70,000 and the used Samsung Galaxy S24 256GB costs KSh 53,000. Both are compact phones with similar screen sizes and camera layouts. The Samsung Galaxy S25 adds the faster Snapdragon 8 Elite chip, more RAM, Wi-Fi 7 and a longer remaining update window, since it launched a year later. Pick the Samsung Galaxy S24 for calls, social media and photos; pick the Samsung Galaxy S25 for gaming, AI tools and keeping your phone five years.
Will the Samsung Galaxy S25 work on Safaricom 5G and cope with Kenyan dust and heat?
Yes, the Samsung Galaxy S25 connects to Safaricom 5G through band n78 and to Safaricom, Airtel Kenya and Telkom 4G through bands 1, 3, 8, 20 and 28. Its IP68 rating keeps out fine dust on Thika Road and rain in Kisumu, and it survives water to 1.5m for 30 minutes. In hot weather, avoid leaving it on a car dashboard. International units accept two nano-SIMs or one nano-SIM with an eSIM, so confirm your unit's layout on WhatsApp.
Is this Samsung Galaxy S25 used or refurbished, and what is the difference?
This Samsung Galaxy S25 is used, meaning it was lightly used internationally, never deployed locally in Kenya, and kept with its original build. Refurbished stock has gone through repairs and certification by the manufacturer or an approved centre. Mascom International sells this phone in the condition it arrived, after testing it in our Nairobi CBD store. Battery health, small scuffs and SIM layout vary between units, so ask for photos and the battery figure of your exact phone on WhatsApp.
How long does the Samsung Galaxy S25 battery last on one charge?
The 4000mAh battery in the Samsung Galaxy S25 lasts a full day for light and moderate users, helped by its efficient 3nm chip. Heavy gamers and creators shooting lots of 4K video may want a top-up by evening. With a 25W Samsung charger it reaches about 50 percent in 30 minutes, and it supports 15W wireless charging on Qi pads. Battery health on used stock varies, so we share the reading of your unit before you commit.
Can the Samsung Galaxy S25 run games like Genshin Impact and Call of Duty Mobile?
Yes, the Samsung Galaxy S25 runs Genshin Impact, Call of Duty Mobile and Asphalt Legends on high settings with its Snapdragon 8 Elite and Adreno 830 graphics. The 120Hz screen keeps fast scenes fluid, and 12GB of RAM lets Discord or WhatsApp stay open beside the game. The compact body warms faster than larger phones during long sessions, so mobile gamers in Kenya often add a slim cooling case. For bigger on-screen controls, consider the Samsung Galaxy S24 Plus instead.
Is the Samsung Galaxy S25 a good phone for developers and journalists?
Yes, the Samsung Galaxy S25 works well for developers and journalists who need speed in a small phone. Plug a USB-C cable into a monitor and Samsung DeX gives you a desktop layout for email, documents and remote terminals. Wi-Fi 7 speeds up large uploads on new routers, and the recorder app can transcribe interviews. Reporters covering stories from Parliament Road to Eldoret tell us the light 162g body is easy to carry all day.
Who should buy the Samsung Galaxy S25 and who should skip it?
Buy the Samsung Galaxy S25 if you want the newest chip in this group, a compact body and Android updates into the 2030s. It suits developers, journalists and anyone who types one-handed. Skip it if you watch a lot of video or read long documents: the Samsung Galaxy S24 Plus at KSh 65,000 gives a bigger screen and battery. Need a stylus and long zoom? The used Samsung Galaxy S25 Ultra 256GB costs KSh 99,000. Tighter budgets suit the Samsung Galaxy S24 FE at KSh 47,000.
Technical Specifications
Display
- 6.2-inch Dynamic LTPO AMOLED 2X — compact enough for one-handed typing, with LTPO dropping the refresh rate on static screens to save power.
- 1080 x 2340 resolution, about 416 pixels per inch — crisp text and photos on a pocket-sized screen.
- 120Hz adaptive refresh — smooth scrolling and gaming, slowing down when the picture is still.
- 2600 nits peak brightness and HDR10+ — clear under strong sun, with proper HDR on streaming apps.
- Gorilla Glass Victus 2 front and back with an Armor Aluminum 2 frame — stronger glass and a tougher frame for daily knocks.
Processor and Performance
- Snapdragon 8 Elite built on a 3nm process — the same chip in every Samsung Galaxy S25 unit, with no regional variation.
- Eight cores, two at 4.47GHz and six at 3.53GHz — every core is a fast one, so apps open quickly under heavy load.
- Adreno 830 graphics — high frame rates in 3D games and fluid 4K video editing.
- Android 15 at launch with seven major Android upgrades promised — updates and security patches into the early 2030s.

Memory and Storage

- Roughly 65,000 standard photos fit in the 200GB or so left free after Android and preinstalled apps.
- Nine hours, give or take, of 4K footage at 30fps fits in that same space.
- No memory card slot — rely on cloud backup or a USB-C drive to free up space.
Camera and Imaging
- 50MP main sensor, f/1.8, 1/1.56-inch size, with optical stabilisation — a larger sensor gathers more light for cleaner evening photos.

Battery and Charging
- 4000mAh battery — a full day for light and moderate users; heavy gamers may want an evening top-up.
- 25W wired charging — about 50 percent in 30 minutes with a 25W Samsung charger, sold separately.
- 15W wireless charging, Qi2 Ready — works on Qi pads, while magnetic Qi2 accessories need a compatible case.
- 4.5W reverse wireless charging — share power with Galaxy Buds or a smartwatch.
- Efficient 3nm chip — the smaller process uses less energy per task, helping the battery stretch further.
Connectivity
- 18 5G bands including n1, n3, n28 and n78, plus 4G bands 1, 3, 8, 20 and 28 — covers Safaricom, Airtel Kenya and Telkom.

- Bluetooth 5.4 and NFC — efficient wireless audio and tap-to-pay with Google Wallet where supported.
- USB Type-C 3.2 with DisplayPort 1.2 — mirror the screen or run Samsung DeX on a monitor.
- Two nano-SIMs or nano-SIM plus eSIM on international units — two active lines on one phone.
- IP68 rating and 162g weight — resists dust and water to 1.5m for 30 minutes, light enough to forget in a pocket.
