Best Budget Gaming Smartphones with Cooling System in 2025 – Real Performance, Real Value
Gaming on smartphones is no longer just about a good processor or flashy display. If your phone heats up, drains fast, or starts lagging mid-match, even the best specs can’t save your experience.
That’s where cooling and battery management step in.
In 2025, most high-end phones can run heavy games. But not all of them can sustain performance without thermal throttling, especially in long sessions.
If you’re a BGMI, COD Mobile, or Genshin player, or even someone who enjoys casual titles, a good cooling system and long-lasting battery are now must-haves.
We’ve compared the best budget gaming smartphones with cooling system in 2025, looking beyond just the chip. And looking into cooling, battery, display, design, and real-world usage.
Let’s dive in.
1. Asus ROG Phone 9 Pro
If you want a solid gaming phone that also doubles up for day-to-day use, the ROG Phone 9 Pro deserves attention.
It features:
- A Snapdragon 8 Elite chip,
- 185Hz LTPO AMOLED display, and
- Support for external active cooling.
You even get a side-mounted USB-C port, so your hands don’t block the charger while gaming. The inbuilt thermal management handles long sessions smoothly.
This phone isn’t just about gaming though. It also offers:
- A stabilized 50MP camera,
- A 3x zoom lens, and
- Gimbal-like video stabilization for creators.
It’s premium, balanced, and built for those who play often but not just play.
2. RedMagic 10S Pro
Looking for raw power, active cooling, and aggressive pricing?
The RedMagic 10S Pro stands out with:
- Built-in cooling fan
- Vapor chamber
- 7050mAh battery
- 100W fast charging
- 144Hz AMOLED display
This phone doesn’t pretend to be a sleek flagship. In fact, it looks bold with RGB lights and a semi-transparent back. But inside, it’s all about stability and heat control.
You also get:
- Shoulder triggers
- Stereo speakers
- Game Mode switch
If you play for hours and want a phone that won’t sweat, this is one of the best budget gaming smartphones with a proper cooling system in 2025.
3. OnePlus 13s
OnePlus surprised everyone this year with the 13s. It may look like a regular flagship, but under the hood, it’s been tuned for sustained performance.
It features:
- Snapdragon 8 Gen 3 Elite
- Cryo-velocity graphite cooling system
- 5850mAh battery
- 80W fast charging
It’s one of the lightest phones in its class (just 185g) and still delivers 7+ hours of non-stop BGMI gameplay. If you game a lot but want something compact and stylish, this one deserves a look.
You also get a lifetime green-line screen replacement from OnePlus. If you missed the launch, here’s a quick refresher on how the OnePlus 13s seems to have changed everything and why it matters for gamers and flagship buyers alike.
4. Poco F7 Ultra
The Poco F7 Ultra isn’t a “gaming phone” on paper, but don’t let that fool you. It checks almost every box:
- Snapdragon 8 Elite chip
- QHD+ AMOLED with 3200 nits brightness
- 5300mAh battery
- 120W wired + 50W wireless charging
- 16GB RAM option
It doesn’t have active cooling like RedMagic, but handles thermals well with internal cooling layers. Add to that a 2.5x zoom camera and Snapdragon Sound, and you’re looking at one of the most complete phones for gaming and daily use without spending ₹1 lakh.
Curious about the India launch? Here’s why the Poco F7 Launch in India is Worth the Wait.
5. Samsung Galaxy S25 Ultra
Samsung’s Galaxy S25 Ultra is not a gaming phone by design, but don’t count it out. It runs a custom Snapdragon 8 Elite chip with slightly higher clock speeds (up to 4.47GHz), and manages heat with efficient internal controls.
What you get:
- 6.9″ AMOLED display with 2600 nits brightness
- 5000mAh battery
- 7 years of Android updates
- IP68 rating
- Samsung DeX for desktop gaming
If you’re a gamer who also wants flagship cameras, smooth One UI, and solid durability, this is a future-proof pick.

6. Samsung Galaxy M36 5G
While not made for pro gaming, the Galaxy M36 5G is ideal if you’re a casual gamer looking for AI features and long-term software support.
Specs include:
- 6.7” sAMOLED display
- 5000mAh battery
- Gorilla Glass Victus+
- AI-enhanced camera with OIS
- 6 years of Android + security updates
The Exynos 1380 chip isn’t the fastest for gaming, but handles most casual games without heating up.
And with features like Circle to Search, Google Gemini integration, and Samsung Wallet, it works great as a daily driver that also lets you unwind with a few rounds of Asphalt or Free Fire.
