The world of Teyvat is huge, beautiful and, unfortunately, incredibly demanding on the resources of your device. With every major update, be it a new version of the game or the addition of vast locations like Fontaine or Natlan, the minimum requirements are steadily increasing. Many gamers are faced with an unpleasant situation when their recently current flagship begins to overheat, lose brightness, or experience frame drops at the most crucial moment of the battle.
Finding a device that can really handle high settings without compromise has turned into a complex engineering task. It's not just about processor power, but also about the efficiency of the cooling system, screen quality and optimization of the Android shell. Not every top chipset is capable of unlocking the potential of the game if the phone manufacturer was greedy on heatsinks or vapor chambers. Genshin Impact at high settings without compromise, turned into a difficult engineering challenge. It's not just about processor power, but also about the efficiency of the cooling system, screen quality and optimization of the Android shell. Not every top-end chipset is capable of unlocking the potential of a game if the phone manufacturer was greedy on heatsinks or vapor chambers.
In this material we will analyze in detail why some smartphones fly in Teyvat, while others suffocate after 15 minutes of play. You'll learn what specific specs to look for when choosing, which models perform best in benchmarks and real-world tests, and how to tune your device for maximum performance. The answer to the question of which phone to choose for comfortable gaming depends on many nuances, which we will now discuss.
Selection criteria: why the processor is not everything
The first thing any buyer looks at is the processor model. For a comfortable game Genshin Impact In 2026, the absolute minimum is chips at the level of Snapdragon 8 Gen 2 or Dimensity 9200+. However, the presence of a powerful “stone” in the specifications does not guarantee a stable framerate. Core architecture and process technology play a decisive role in energy efficiency and heat dissipation.
The memory subsystem is of great importance. The game actively works with texture data, so the standard LPDDR5X and storage UFS 4.0 are prerequisites for fast loading of locations and the absence of micro-freezes when moving the character. If the phone is equipped with older memory, even a powerful processor will be idle waiting for data.
Software optimization cannot be ignored. Some manufacturers are introducing their own gaming modes that aggressively manipulate frequencies to conserve battery power at the cost of performance. Others, on the contrary, allow you to squeeze the most out of the hardware, sacrificing autonomy. It is important to understand exactly how your future smartphone manages resources under load.
⚠️ Attention: Characteristics in specifications are often written “to the last transistor”. Real performance in long sessions depends on how quickly the device goes into throttling (a decrease in frequencies due to heating).
Pay attention to smartphones with an active or passive cooler included. For Genshin Impact, this is a critical accessory that allows you to maintain maximum processor frequencies for hours.
Rating of the best processors for the mobile version of the game
Qualcomm solutions unconditionally remain the market leader. Flagship chipsets of the series Snapdragon 8 Gen 3 and newer demonstrate better compatibility with the game engine and Adreno drivers. High GPU performance allows you to render complex particle and shadow effects without significant frame loss, even at resolutions above 1080p.
Competitors from the MediaTek camp also showed impressive results. Top solutions Dimensity 9300+ and subsequent versions often surpass their counterparts in multi-threaded performance, which has a positive effect on background stability and the operation of background system processes during the game. However, sometimes they may require more fine-tuning of emulators or drivers.
The middle segment is represented by chips like Snapdragon 7+ Gen 3. They are able to run the game at medium settings with an acceptable framerate, but you shouldn’t count on ultra-graphics here. Such processors are suitable for those who are willing to sacrifice picture quality for a more affordable price of a smartphone.
- 🚀 Snapdragon 8 Elite / Gen 4: The absolute leader, can handle everything at ultra with a reserve.
- ⚡ Dimensity 9300+ / 9400: An excellent alternative, often cheaper than analogues from Qualcomm.
- 🛡️ Snapdragon 8 Gen 2: the current "people's" flagship for stable 60 FPS.
- 📉 Snapdragon 7+ Gen 3: Budget option only for medium graphics settings.
Cooling system: battle with overheating
The biggest enemy of a mobile game is heat. When the temperature of the case or internal components reaches a critical level, the protection system automatically reduces the processor clock speed. Visually, this manifests itself as a sharp drop in FPS: the game started briskly, and after 20 minutes it turned into a slide show.
Manufacturers of gaming smartphones, such as ASUS ROG Phone, RedMagic or Black Shark, rely on advanced heat dissipation systems. The use of massive vapor chambers, graphene layers and even built-in fans allows you to maintain peak performance indefinitely. Conventional flagships often suffer from compact bodies, where there is simply no room for effective cooling.
The case material also plays a role. Glass and plastic back covers are less efficient at dissipating heat than metal frames or specialized composite materials. If you are planning long sessions in Teyvat, the presence of perforations in the case or a special port for connecting an external cooler will be a strong buying argument.
| Cooling type | Efficiency | Impact on weight | Example devices |
|---|---|---|---|
| Passive (graphene) | Low | No effect | Budget models |
| Evaporation chamber | Medium | Minimum | Most flagships |
| Active fan | High | Noticeable | RedMagic, ROG Phone |
| Liquid (external) | Extreme | Depends on the cooler | Any phone + accessory |
⚠️ Attention: Do not use cases during long gaming sessions if your smartphone does not have a special ventilation system. The case creates a “thermos” effect, accelerating overheating.
Why does the game slow down after 30 minutes?
This is a classic sign of throttling. The processor heated up to 45-50 degrees, and the power controller forcibly cut the frequencies by 30-40% to prevent damage to the crystal. Without additional cooling, it is impossible to return to the previous performance until it cools down.
Screen and controls: comfort in battle
Image quality in Genshin Impact directly depends on the resolution and type of matrix. AMOLED screens with high peak brightness allow you to enjoy the game even in the sun, and HDR support improves the perception of shadows and light in caves or underwater. However, high resolution (2K and higher) creates additional load on the GPU, reducing FPS.
The screen refresh rate is a critical parameter for dynamic battles. Availability of mode 120 Hz or 144 Hz makes camera movements and character attacks incredibly smooth. It is important to check in the game settings whether a specific smartphone model supports high Hertz, as sometimes developers block this mode for some devices.
The touch sampling rate determines how quickly the phone responds to your touches. In action games where you need to dodge boss attacks in a split second, 240 Hz and above gives a noticeable advantage over the standard 120 Hz. Input lag should be minimal.
- 🖼️ Resolution: 1080p+ - the optimal balance of picture and performance.
- 🔄 Hertzovka: 120 Hz is required for smooth animations.
- 👆 Sensor: 240 Hz+ response for instant response in battle.
- ☀️ Brightness: 1000 nits+ for outdoor play.
For Genshin Impact, it is better to choose a screen with a resolution 1.5K (1220p) instead of full 2K. You will hardly notice the difference in clarity on a 6-inch diagonal, but the load on the video accelerator will decrease significantly.
Top smartphones for Genshin Impact in 2026
If you are looking for a ready-made solution without compromises, you should pay attention to specialized gaming models. Smartphones of the series RedMagic 10 Pro or ASUS ROG Phone 9 are created specifically for such tasks. They have an aggressive design, triggers on the body and, most importantly, a phenomenal cooling system that allows you to play at maximum speed for hours.
Among the universal flagships, Xiaomi 15 Ultra and Samsung Galaxy S26 Ultrastand out. They offer the best balance between camera, screen and performance. While they may run a little faster than gaming monsters, their optimization and display quality make for visually stunning gameplay. Often special drivers are released for them that improve performance in heavy games.
The budget segment is represented by models like POCO F6 Pro or Realme GT Neo. These devices use flagship processors from previous years or stripped-down versions of current ones, allowing them to deliver excellent gaming performance at a significantly lower price. The only negative is that the materials of the case and camera are usually inferior to top models.
☑️ Checklist before buying a gaming smartphone
Optimization and settings for maximum FPS
Even the most powerful phone requires correct settings. Go to the developer settings and make sure the option 4x MSAA is enabled (if available), although in the case of Genshin Impact it is better to rely on the in-game settings. Disabling unnecessary animations in the system can free up some resources for rendering.
In the game itself, it is recommended to experiment with the shadows and anti-aliasing settings. Often, reducing the quality of shadows from “High” to “Low” gives an increase of 10-15 frames, with almost no effect on the visual perception of gameplay. It is better to disable dynamic motion blur - it eats up resources and interferes with aiming.
Use the game modes built into the Android shell (Game Turbo, Game Launcher). They allow you to block notifications, turn off automatic brightness, and lock the processor to maximum performance. Some shells allow you to create profiles for specific games with individual frequency settings.
Settings -> About phone -> MIUI version (press 7 times) -> Developer settings -> Disable HW overlay⚠️ Attention: Interfaces and names of menu items may differ depending on the version of Android and the manufacturer's shell (OneUI, HyperOS, ColorOS). Always check the latest guides for your specific model.
Before starting a heavy session, close all background applications and clear your RAM. Genshin Impact likes to take up to 4-5 GB of RAM, and any lack of memory will result in micro-stuttering.
Frequently asked questions (FAQ)
Can my current Genshin Impact phone run on ultra?
It depends on the processor. If you have a Snapdragon 865 or newer, or Dimensity 1000+ and above, the game will run. However, stable 60 FPS at ultra settings is only possible on chips of the Snapdragon 8 Gen 2 level and newer. On older models, you will have to lower the graphics settings.
How much memory is needed for a comfortable game?
The minimum comfortable amount of RAM in 2026 is considered 8 GB. However, for the game without crashes and with the ability to keep other applications open, the version with 12 GB or 16 GB RAM is highly recommended. The built-in memory should be at least 256 GB, since the weight of the game with updates exceeds 30 GB.
Will an external cooler help increase FPS?
Yes, an external active cooler (fan with a Peltier element) is the most effective solution for combating throttling. It allows the processor to maintain maximum frequencies for much longer, which directly affects the stability of frames per second, especially in long battles.
Is playing Genshin Impact harmful to your phone battery?
Long-term load at high temperatures accelerates the degradation of the lithium-ion battery. Try not to play while charging if the phone gets too hot, and don't let the case regularly overheat above 45 degrees. Using external cooling extends the life of the battery.
