For buyers seeking a fast gaming phone, I rank the OnePlus 15R as the best overall pick because its 165Hz AMOLED display, Snapdragon 8 Gen 5 processor, and 7,400mAh battery directly address demanding play. The Samsung Galaxy S26+ is my premium all-rounder, pairing flagship performance with 512GB of storage and stronger everyday features. Buyers who want proven flagship hardware for less should examine the Galaxy S25+, while the renewed S23+ offers the lowest-cost route to a former high-end model.

The main choice is between gaming-focused hardware and broader phone quality. OnePlus supplies the fastest display and largest battery here, but Samsung offers a more mature mix of cameras, security, accessories, and long-term usability. Price also changes the ranking: a newer processor may offer more headroom, while an older flagship can still deliver smooth games without demanding the largest budget. I weigh those differences below so each recommendation has a clear buyer rather than treating all five phones as interchangeable.

More Details on Our Top Picks
OnePlus 15R, 12GB RAM + 256GB Storage
I place the OnePlus 15R at number one because nearly every headline specification supports gaming. Its Snapdragon 8 Gen 5 processor and 12GB of RAM provide the strongest stated performance foundation in this group, while the 165Hz AMOLED display can make compatible games and interface movement appear more fluid. That refresh rate exceeds the display information supplied for every Samsung model here, making this the clearest choice for players who prioritize responsiveness.
The 7,400mAh battery creates another meaningful gap. It offers far more listed capacity than the S25+’s 4,900mAh or the A37’s 5,000mAh battery, and 80W SUPERVOOC charging reduces waiting when it runs down. Actual endurance will still depend on brightness, network use, and frame rate. I also like the dual-SIM support and water-resistant construction for daily flexibility.
This is not the automatic choice for everyone. The 256GB storage ceiling is less generous than the S26+’s 512GB, camera details are sparse, and there is no headphone jack. Buyers invested in Samsung services may also prefer the S26+. I rank the OnePlus higher because the hardware advantages are more relevant to sustained gaming than Samsung’s extra photo and ecosystem features.
Pros:- Snapdragon 8 Gen 5 and 12GB RAM provide a strong performance base
- 165Hz AMOLED display supports exceptionally fluid compatible games
- Large 7,400mAh battery suits extended sessions
- 80W charging and dual-SIM support add practical flexibility
Cons:- No headphone jack
- 256GB may feel restrictive with several large games installed
- Camera capabilities are less clearly described than Samsung’s
Best for: Players who prioritize high refresh rates, long sessions, fast charging, and strong Android performance.
Not ideal for: Buyers who need 512GB of storage, wired headphones without an adapter, or Samsung ecosystem features.
- Operating System:Android 15
- Processor:Snapdragon 8 Gen 5, up to 3.8GHz
- RAM:12GB
- Storage:256GB
- Display:165Hz AMOLED
- Battery:7,400mAh
- Charging:80W SUPERVOOC
- SIM:Dual SIM
- Water Protection:Water-resistant design
Our verdict“My first choice for serious mobile gaming pairs the lineup’s fastest listed display with its largest battery.”
Samsung Galaxy S26+ Unlocked, 512GB
The Samsung Galaxy S26+ takes second place because it combines flagship-class processing with the most generous storage in the lineup. Its 512GB capacity is valuable when premium games, downloaded media, and captured video all share one device. Samsung describes the processor as its fastest and AI-accelerated, while the ultra-vivid display targets sharp, colorful presentation. I see it as the better premium purchase for someone who games heavily but does not want a gaming-first phone.
Compared with the OnePlus 15R, the S26+ lacks supplied figures for refresh rate, battery capacity, RAM, and charging speed. That missing detail keeps it out of first place under a high-performance gaming lens. In return, buyers get stronger creative and daily-use tools, including AI photo editing, a wider front camera, Samsung Wallet integration, and close pairing with Galaxy Buds4 Pro.
Those extras have limits. Some AI functions require internet access, edited photos may be resized or marked, and certain services could carry added fees. The compatible earbuds are also a separate purchase. I would pay the premium for storage and ecosystem polish, not because this listing proves better gaming endurance than the OnePlus.
Pros:- 512GB provides ample room for large games and media
- AI-accelerated flagship processor supports demanding workloads
- Vivid display and Hi-Res Audio compatibility strengthen multimedia use
- Samsung Wallet and creative tools add everyday value
Cons:- Key gaming figures such as refresh rate and battery capacity are not supplied
- Several AI tools require an internet connection
- Some features may involve fees, subscriptions, resizing, or watermarks
Best for: Premium buyers who split their time between demanding games, photography, media, and Samsung-connected services.
Not ideal for: Spec-focused players who want clearly stated battery, RAM, refresh-rate, and charging figures.
- Storage:512GB
- Color:Sky Blue
- Processor:AI-accelerated Galaxy flagship processor
- Display:Ultra-vivid display with auto-enriching colors
- Front Camera:Wide lens for group selfies
- Audio:Hi-Res Audio with compatible Galaxy Buds4 Pro
- Wallet:Samsung Wallet support
Our verdict“I recommend the S26+ to premium buyers who want fast gaming within a polished, storage-rich everyday flagship.”
Samsung Galaxy S25+ Unlocked, 256GB
I rank the Galaxy S25+ third as the sensible middle ground. Its Snapdragon 8 Elite processor remains the feature that matters most for this guide, giving demanding games far more performance headroom than the A37’s midrange Exynos chip. The 4,900mAh battery is sized for substantial daily use, and Samsung’s ProScaler display processing can improve the appearance of lower-resolution content.
Against the S26+, the S25+ sacrifices 256GB of storage and the newer model’s claimed processing advances. It may compensate with a lower purchase price, making it a better fit when the newest generation carries a steep premium. Compared with the OnePlus 15R, however, it has a much smaller battery and no stated 165Hz panel or 80W charging. I would choose it for balanced flagship ownership, not maximum session length.
The large body may be awkward for smaller hands, and a high price can weaken its value advantage. Its AI Night Mode and portrait tools are useful beyond gaming, while the one-year US warranty adds clarity that the renewed S23+ cannot match. For many buyers, this is the least compromised Samsung value in the ranking.
Pros:- Snapdragon 8 Elite offers high-end gaming performance
- 4,900mAh battery supports substantial daily use
- ProScaler display processing can sharpen supported content
- One-year US warranty provides straightforward coverage
Cons:- Battery is much smaller than the OnePlus 15R’s
- Large dimensions may be uncomfortable for some buyers
- 256GB storage offers less room than the Galaxy S26+
Best for: Samsung buyers who want modern flagship speed without automatically paying for the newest generation.
Not ideal for: Players seeking the largest battery, the fastest stated refresh rate, or a compact handset.
- Processor:Snapdragon 8 Elite
- Storage:256GB
- Battery:4,900mAh
- Display Technology:ProScaler
- Camera:AI Night Mode and portrait features
- Color:Navy
- Warranty:One-year US warranty
Our verdict“The S25+ is my balanced Samsung pick when current flagship speed matters more than owning the latest model.”
Samsung Galaxy S23+ 5G, 256GB, Renewed
The renewed Galaxy S23+ earns fourth place by offering former flagship hardware at a potentially lower price. Its Snapdragon 8 Gen 2 processor and 8GB of RAM remain a credible combination for popular competitive games and graphically rich single-player titles. The 6.6-inch Dynamic AMOLED 2X display also supports an adaptive refresh rate, giving it a clearer gaming advantage than the budget A37.
I would choose this over the A37 when frame rates and graphics settings matter more than software lifespan or a brand-new battery. The S23+ also includes a capable 50MP main camera, 5G, dual-SIM support, and a bright panel suited to outdoor viewing. It cannot match the OnePlus 15R’s listed processor generation, huge battery, or 165Hz ceiling, which explains the lower position.
Renewed condition is the defining tradeoff. Battery health may vary, minor cosmetic wear is possible, and seller-specific coverage needs careful review. The listed 4,700mAh capacity was already the smallest in this group before prior use entered the equation. There is no headphone jack either. I see it as a price-led performance buy, provided the return policy is strong and the discount is meaningful.
Pros:- Snapdragon 8 Gen 2 still provides capable gaming speed
- Adaptive Dynamic AMOLED 2X display suits fast-moving games
- 256GB storage is practical for a mixed game library
- Renewed pricing may undercut newer flagship phones
Cons:- Battery health and cosmetic condition can vary
- 4,700mAh listed capacity trails the other models
- No headphone jack
Best for: Value seekers who want flagship-grade Samsung performance and accept the variables attached to a renewed phone.
Not ideal for: Buyers who want a new battery, pristine condition, the longest support horizon, or predictable warranty coverage.
- Processor:Snapdragon 8 Gen 2, 2.8GHz
- RAM:8GB
- Storage:256GB
- Display:6.6-inch Dynamic AMOLED 2X
- Battery:4,700mAh
- Rear Camera:Triple camera system with 50MP main sensor
- Connectivity:5G, dual SIM, and USB Type-C
- Condition:Renewed
Our verdict“I would buy the renewed S23+ only when its discount clearly offsets condition and battery-health uncertainty.”
Samsung Galaxy A37 5G, 128GB
I place the Galaxy A37 fifth, but it fills a useful role for buyers whose gaming consists of lighter titles, cloud streaming, or occasional sessions. Its 6.7-inch Super AMOLED display offers an expansive, colorful view, and the 5,000mAh battery has more listed capacity than either the S25+ or S23+. IP68 protection and a one-year warranty also make it an appealing everyday phone.
The performance hierarchy is clear: the Exynos 1480 is a midrange processor, while the Snapdragon chips in the OnePlus 15R, S25+, and S23+ belong to faster classes. Buyers targeting high graphics settings or stable frame rates in demanding releases should spend more. The A37’s 128GB storage is another constraint, especially because the supplied details state that it lacks expandable memory.
Its six operating-system upgrades and six years of security updates can deliver excellent ownership value, and the 50MP HDR main camera broadens its appeal. Super Fast Charging 2.0 requires a separately purchased charger, though. I recommend this model when budget and longevity outrank peak speed; it is not a cheaper substitute for the gaming capability of the first four phones.
Pros:- Large 6.7-inch Super AMOLED display
- 5,000mAh battery supports long mixed-use days
- IP68-rated body offers useful dust and water protection
- Six OS upgrades and six years of security updates add longevity
Cons:- Exynos 1480 trails the flagship processors in this lineup
- 128GB storage is limited and not expandable
- Fastest supported charging requires a separate charger
Best for: Casual players who want a new Samsung phone, a large AMOLED screen, durability, and long software support.
Not ideal for: Players running demanding games at high settings or storing a large library locally.
- Processor:Exynos 1480
- Display:6.7-inch Super AMOLED
- Storage:128GB
- Battery:5,000mAh
- Charging:Super Fast Charging 2.0
- Camera:Triple-lens system with 50MP HDR main camera
- Water and Dust Protection:IP68
- Software Support:Six OS upgrades and six years of security updates
- Warranty:One year
Our verdict“The A37 is my budget choice for casual play, but demanding gamers should move higher in the ranking.”
How We Picked
I ranked these phones around the demands that affect play rather than treating a strong camera as proof of gaming ability. My primary factors were processor class, display responsiveness, battery capacity, and charging speed. Those traits shape frame-rate stability, control response, session length, and the amount of downtime between sessions. I also weighed RAM and storage because modern games can occupy many gigabytes and compete with background apps for memory.
I then examined the compromises outside raw speed. A gaming phone is still likely to serve as a buyer’s camera, wallet, media player, and daily communication device. That gives the Galaxy S26+ and S25+ broader appeal, even though the OnePlus has more gaming-oriented numbers. Durability, software support, warranty coverage, size, audio options, and the absence of a headphone jack also shaped my order.
This ranking uses the specifications supplied for each listing rather than hands-on benchmark results. I give greater weight to clear, relevant specifications than to broad performance claims. That is why the OnePlus 15R leads on gaming hardware, while the A37 ranks fifth despite its attractive AMOLED screen and long software policy. For the renewed S23+, I also account for condition and battery uncertainty, which are part of buying any refurbished device.
| gaming smartphones for high performance | Processor |
|---|---|
| OnePlus 15R | Snapdragon 8 Gen 5, up to 3.8GHz |
| Samsung Galaxy S26+ Unlocked | AI-accelerated Galaxy flagship processor |
| Samsung Galaxy S25+ Unlocked | Snapdragon 8 Elite |
| Samsung Galaxy S23+ 5G | Snapdragon 8 Gen 2, 2.8GHz |

Factors to Consider When Choosing Gaming Smartphones For High Performance
I would choose a gaming smartphone by matching its hardware to the games, session length, and ownership period I actually expect. A high-end processor matters, but display behavior, battery size, storage, and charging can change daily enjoyment just as much.
Match the Processor to Your Games
For demanding 3D games, I favor a recent flagship Snapdragon processor because it provides more room for high graphics settings, faster loading, and future game updates. That places the OnePlus 15R and Galaxy S25+ ahead of the A37 on raw positioning. The renewed S23+’s Snapdragon 8 Gen 2 is older, yet it remains a better performance bet than a current midrange chip when the price is right. Casual puzzle, card, and streaming-based games rarely require the most expensive silicon, so the A37 can still be the smarter purchase for light use.
Refresh Rate and Battery Work Together
A fast panel improves motion only when the game and processor can deliver enough frames. The OnePlus 15R’s 165Hz AMOLED display supplies the highest stated ceiling here, making it attractive for compatible competitive games. Running high frame rates also consumes more power, which makes its 7,400mAh battery especially relevant. Samsung’s flagship displays remain appealing, but the supplied S26+ details omit an exact refresh rate. I would not choose from display marketing alone; I would pair screen speed with battery capacity and the games I play.
Plan Storage Around Large Game Libraries
Game installations can grow after texture packs, voice files, and seasonal updates arrive. I view 256GB as a practical starting point for a buyer who keeps several large games, photos, and offline video on one phone. The S26+’s 512GB offers the most breathing room, while the A37’s 128GB may require frequent cleanup. Since cloud saves do not eliminate local installation sizes, extra storage can be more useful than a camera feature that sees little use. I would choose 512GB for long ownership or 256GB for a more price-conscious library.
Account for Heat, Charging, and Accessories
Processor labels do not reveal how a phone handles heat during a long match, so I would check independent sustained-performance results before buying. Charging speed also affects whether a brief break restores enough power for another session. The OnePlus has the clearest advantage on paper with 80W charging, while the A37 requires a separate charger for its fastest supported rate. None of these models includes a headphone jack in the supplied details where that feature is specified. Players using wired gaming headsets may need a USB-C adapter or compatible controller.
Frequently Asked Questions
Which phone in this roundup is best for demanding games?
I pick the OnePlus 15R for demanding games because its Snapdragon 8 Gen 5 processor, 12GB of RAM, 165Hz AMOLED screen, and 7,400mAh battery form the strongest stated gaming combination. The Galaxy S26+ may be the better all-purpose premium phone, but its supplied specifications do not provide the same level of detail about refresh rate, RAM, battery capacity, or charging.
Is the Galaxy S26+ better than the OnePlus 15R for gaming?
I would choose the OnePlus 15R for gaming alone and the Galaxy S26+ for a broader premium experience. OnePlus offers a clearly stated 165Hz display, larger battery, 80W charging, and 12GB of RAM. The S26+ counters with 512GB of storage, Samsung services, creative AI tools, and stronger ecosystem integration, which may matter more when the phone has many jobs beyond gaming.
Can the Samsung Galaxy A37 run modern mobile games?
The Galaxy A37 should suit casual and moderately demanding games, but its Exynos 1480 processor is not positioned alongside the flagship Snapdragon chips in the other models. I would expect buyers of graphically intensive games to lower settings more often. Its large AMOLED display and 5,000mAh battery are attractive, yet 128GB of fixed storage also limits how many large titles can remain installed.
Is a renewed Galaxy S23+ a good gaming-phone purchase?
A renewed S23+ can be a strong value at the right discount. The Snapdragon 8 Gen 2, 8GB of RAM, and adaptive AMOLED display still form a capable package. I would verify the seller’s return policy, warranty, grading standard, and battery guarantee before ordering. If the price approaches a new S25+ or OnePlus 15R, the newer phone is the safer buy.
How much storage should a gaming smartphone have?
I recommend at least 256GB for frequent gaming, especially when the phone also stores photos and offline media. A few large games plus downloaded content can make 128GB feel cramped quickly. The Galaxy S26+’s 512GB is the easiest choice for a large long-term library, while the A37 demands more storage management. Buyers who stream most media may find 256GB offers the best balance of space and cost.
Conclusion
For the strongest gaming hardware in this group, I would buy the OnePlus 15R; its fast display, huge battery, and rapid charging give it the clearest performance-focused identity. I recommend the Galaxy S26+ for premium all-rounder buyers who want 512GB and Samsung’s broader feature set. The S25+ is my choice for buyers seeking modern flagship speed at a potentially better price, while the renewed S23+ suits bargain hunters willing to inspect seller protections closely. I would reserve the Galaxy A37 for casual players focused on affordability and long software support. The right choice depends on whether peak frame-rate potential, daily versatility, purchase price, or ownership longevity carries the most weight.
