Best Refurbished Gaming Phones Under £400 in the UK

The best refurbished gaming phones under £400 in the UK are usually iPhone 13 models, with the iPhone 13 Pro worth considering when its 120Hz display fits your budget. They offer strong graphics performance, OLED screens, 5G and current software without the cost of a new iPhone.

Gaming puts more pressure on a phone than messaging or browsing. Battery health, heat, storage and a straight frame matter more than a few marks on the casing. These are the Apple models we’d focus on first.

Best Option for Most Buyers

• Choose the iPhone 13 for the best balance of price, battery life and gaming performance.
• Pick the iPhone 13 Pro if a 120Hz display matters and you find one with healthy battery performance.
• Consider the iPhone 14 when the price gap is small, especially if you want a newer A15 chip variant and longer ownership potential.
• Look for 128GB as a minimum, but choose 256GB if you download several large games or record lots of video.
• Avoid any phone with a bent frame, unreliable charging, liquid damage or a poor repair history.

Best refurbished gaming phones under £400

At August 2026 UK prices, many refurbished 128GB iPhone 13 listings sit around £219 to £350. Grade, storage, battery health, warranty and availability can move the price considerably. Higher-storage versions and Pro models may approach or exceed £400.

That pricing makes the iPhone 13 particularly interesting for buyers comparing refurbished iPhones. Wider UK refurbished phone guides also place recent iPhones among the stronger choices for gaming and general use.

iPhone 13, the strongest value choice

The iPhone 13 uses Apple’s A15 Bionic chip and has a 6.1-inch OLED display. It can handle demanding games at sensible settings, while its compact size makes it comfortable to hold for longer sessions.

Its 60Hz refresh rate is the main limitation for competitive gaming. Games still look sharp and responsive, but scrolling and supported gameplay feel smoother on the iPhone 13 Pro.

The 128GB model suits most casual and regular players. However, large game downloads, photos and video can fill it quickly. If the 256GB version costs only a little more, it may be the better long-term buy.

The iPhone 13 supports iOS 26 in 2026, so it remains a sensible choice for buyers who want several more years from a refurbished iPhone. It also supports 5G and MagSafe, although it uses a Lightning connector rather than USB-C.

iPhone 13 Pro, the best gaming-focused option

The iPhone 13 Pro is the model to target when gaming matters more than keeping the price as low as possible. Its 120Hz ProMotion display makes supported games, menus and scrolling feel noticeably smoother.

It also uses an A15 Bionic chip with a five-core GPU, giving it a little more graphics headroom than the standard iPhone 13. The larger battery and brighter display can make it a better choice for longer sessions, although battery condition still decides how it behaves in real use.

A refurbished 13 Pro can appear close to the £400 mark, but stock is less consistent. At this price, we’d prioritise battery health, screen quality and warranty over colour or small cosmetic marks.

The Pro model also has more expensive components to assess. The OLED display, camera system and stainless steel frame need careful checking after previous drops. A clean-looking phone with a tired battery or uneven screen is not a good gaming bargain.

iPhone 14, a newer alternative

The standard iPhone 14 keeps a 60Hz display, so it doesn’t provide the smoothness of the 13 Pro. However, its A15 Bionic chip has a five-core GPU, and it remains capable with demanding games, multitasking and recording gameplay.

Choose it when the price is close to an iPhone 13 and you plan to keep the phone for longer. If the iPhone 14 costs noticeably more, the iPhone 13 usually delivers better value for ordinary gaming.

The iPhone 14 also uses Lightning and supports MagSafe. Buyers moving to USB-C will need to look at a newer model, but sacrificing battery health or warranty to get a different connector is rarely sensible.

How gaming feels in everyday use

The best refurbished gaming phones under £400 should keep games stable during a normal session, not merely produce impressive benchmark results. An iPhone 13 or 14 is suitable for popular online games, racing titles and action games, although maximum graphics settings can increase heat and battery drain.

Gaming uses considerably more power than messaging, banking or watching short videos. A phone with 85% battery health can still be useful, but two otherwise identical examples may offer different session lengths if one battery has seen heavier use.

Heat is another practical concern. Some warmth during a demanding game is normal. Excessive heat, sudden brightness reduction or sharp performance drops suggest that the phone needs closer inspection.

A clean back does not prove a healthy gaming phone. Battery performance and reliable charging matter more than small scratches.

Wi-Fi gives the most stable connection at home. 5G helps when you play away from your broadband connection, but network coverage still affects online performance. A strong signal and a reliable modem matter more than simply seeing the 5G symbol.

Storage also affects ownership. A 128GB phone works for lighter users, but 256GB gives more room for games, updates, photos and clips. You shouldn’t need to delete a large game every time Apple releases a software update.

Our Experience Refurbishing This Model at Used Mobiles 4U

Our Apple refurbishment checks cover more than the glass and casing. On iPhone 13 units, we regularly pay close attention to battery wear and the Lightning port. Pocket lint can stop a cable seating correctly, whilst a cable that works only at one angle can point to worn connector contacts.

Cleaning may solve compacted dust, but it cannot repair a damaged port. We test wired charging and data connection instead of assuming the phone is healthy because it works on a wireless charger.

Our technicians check full-screen touch response, Face ID, cameras, microphones, speakers, mobile signal, vibration, wireless charging and battery behaviour. We also look for uneven screen gaps, lifted panels and signs that an earlier repair has left the phone under pressure.

Routine refurbishment work can involve batteries, screens or charging components. A bent frame, liquid exposure or several poor repairs are different matters. These faults can make a handset unsuitable for dependable resale, even when the front display looks good.

At Used Mobiles 4U, refurbished phones are securely data-wiped, tested, unlocked and SIM-free. Stock is supplied with at least 85% battery health, an 18-month warranty and 30-day returns. Those details matter when you’re choosing between cheap refurbished iPhones and a slightly more expensive example with clearer support.

What We Commonly See

• Buyers usually choose the iPhone 13 when they want reliable gaming performance without paying Pro prices.
• The most common concern is battery condition, not light scratching around the frame.
• Customers choose the 13 Pro mainly for its 120Hz display and stronger graphics performance.
• The main fault we check on iPhone 13 models is charging behaviour around the Lightning port.
• Buyers often regret choosing 64GB or 128GB when they keep several large games and record video.
• The iPhone 14 makes more sense when its price is close to the iPhone 13 and longer ownership matters.

What to check before buying

Start with the listing, not the photographs. A refurbished phone should have a clear grade, stated battery policy, warranty terms and returns process. The UK refurbished smartphone market includes sellers with different testing standards, so a low headline price doesn’t tell you everything.

Our used versus refurbished iPhone comparison explains why structured testing and defined grading matter. Before you buy, check the following:

• Confirm that the phone is unlocked and SIM-free for your network.
• Check whether the seller guarantees minimum battery health or merely describes battery condition as variable.
• Look for confirmation that Face ID, cameras, speakers, microphones and touch response have been tested.
• Ask whether the phone has a genuine, refurbished original or aftermarket screen if repair history matters to you.
• Compare storage capacity, warranty length and returns support alongside cosmetic grade.

Be cautious with a phone that charges only when the cable is held at a certain angle. It may need nothing more than port cleaning, but it may also have a worn connector.

The refurbished iPhone buying guide can help if you’re comparing models rather than choosing on price alone. You can also Read Our Refurbished iPhone Buying Guide before deciding which storage and condition best suit your budget.

Repair or replace your current iPhone?

Repair makes sense when the display is the only serious fault, the battery remains dependable, charging works properly and Face ID still functions. Compare the complete repair bill with the realistic value of the phone after repair, including any battery or charging-port work that may become necessary.

Replacement is usually safer when the phone has a bent frame, liquid exposure, weak battery, unreliable charging or several faults. A new screen cannot correct a twisted housing, and fitting one under pressure can lead to later touch problems or another cracked panel.

Back up the iPhone while it still works through iCloud or a computer. If glass is shedding or the display is flickering, stop using it and protect loose glass with tape or a tempered-glass protector only as a temporary measure.

For newer models, Apple or a reputable independent repairer is the safer route. If repair no longer makes financial sense, Sell Your Old Phone and put its remaining value towards a tested replacement.

Final Thoughts

The iPhone 13 is our overall choice for most buyers seeking a refurbished gaming phone under £400. It gives you strong performance, an OLED display, 5G and current software at a price that leaves room for a proper warranty and healthy battery.

Choose the iPhone 13 Pro when its 120Hz screen improves the way you play and its condition is sound. Avoid any model with a bent frame, liquid damage or stacked faults, even if the casing looks attractive. When you’re ready to compare current stock, Browse Refurbished iPhones and focus on battery health and testing before cosmetic grade.

This guide is based on the checks we make when assessing Apple phones for resale, including charging, display, Face ID, battery behaviour and previous repair quality.
