Games on Android freeze and slow down - what to do in 2026?

Game freezing on Android is one of the most annoying problems for gamers. You're in the most interesting moment, and the screen suddenly freezes for a few seconds, or the game crashes completely with an error. The reasons may be different: from an overloaded processor to incompatibility with the version Android. But in 90% of cases, the problem can be solved without contacting a service center.

In this article we will look at all possible causes of lags from banal lack of memory to hidden graphics settings in games. You'll learn how to diagnose the problem, what tools to use for optimization, and when to really think about hardware repair. And also - a list of 5 games that most often cause lags on budget smartphones in 2026.

1. Check the free space on the device

The most obvious, but often ignored reason for the brakes is lack of free space in the internal memory. If there is less than 10% free space left on the device, Android begins to “slow down” background processes, including games. This is especially noticeable on smartphones with 16–32 GB memory.

How to check:

• 📱 Open Settings → Storage.
• 📊 See how much space is occupied in the “Used” section.
• 🔍 Pay attention to the “Other” category - unnecessary files often accumulate there.

What to do:

• 🗑️ Remove unnecessary applications (especially those that have not been used for a long time).
• 🖼️ Transfer photos and videos to the cloud (Google Photos, Yandex.Disk).
• 🎮 Clear the game cache via Settings → Applications → [Game name] → Storage → Clear cache.

2. Close background applications and optimize RAM

Lack of RAM (RAM) —the second most common cause of freezes. Even if you have a smartphone with 6–8 GB RAM, some games (for example PUBG Mobile or Honor of Kings) can take up to 1.5–2 GB memory. peak loads. If messengers, browsers or social networks are running in the background, lags are inevitable.

How to free up RAM:

• 🔄 Use the built-in memory cleaner: press and hold the button Recent applications (usually to the right of the Home button), then tap "Clear all".
• 🚫 Disable auto-start of unnecessary applications in Settings → Applications → Autorun.
• 📱 Install a RAM optimizer (for example RAM Booster or Game Booster 4x Faster), but be careful - some of them consume resources themselves.

For advanced users:

adb shell am kill-all

This command, executed through ADB, will force close all background processes. Use it if standard methods do not help.

3. Update the game, firmware and drivers

Outdated versions of games or firmware Android often contain bugs that cause freezes. For example, in Free Fire version 1.95.1 there was a critical bug with the graphics engine, due to which the game froze on smartphones with processors Mediatek Helio G80.

What to check:

• 🎮 Game update: open Google Play, find the game and click "Update".
• 📱 Update Android: Settings → System → Software update.
• 🔧 Graphics drivers: on some smartphones (for example, Samsung Galaxy or Xiaomi Redmi) driver updates come separately from the firmware. Check in Settings → About phone → GPU version.

⚠️ Attention: If after updating the firmware the games begin to slow down even more, try rolling back to the previous version via Fastboot or TWRP. Some manufacturers (for example, OnePlus or Realme) release “raw” updates with bugs.

4. Adjust the graphics in the game

Many games automatically select graphics settings based on the smartphone model. But sometimes they “overestimate” the capabilities of the device. For example, Genshin Impact on Redmi Note 10 sets the default settings to medium, although for smooth FPS it is better to choose the minimum ones.

How to optimize:

• 🎨 In the game settings, reduce Graphics quality to "Low" or "Medium".
• 🔄 Disable Shadows, Particle effects and Antialiasing —they heavily load the processor.
• 📊 Turn on the "Performance" mode instead of "Quality" (if there is such a parameter).
• 🔋 Activate the "Battery Saving" mode in the game settings - this will reduce the load on the CPU.

An example of optimal settings for weak smartphones (Snapdragon 6xx or Helio Gxx):

Parameter	Recommended value	FPS savings
Resolution	720p (HD)	+15–20%
Graphics quality	Low	+25–30%
Shadows	Disabled	+10–15%
Frame rate	30 FPS (instead of 60)	+40%

How to enable hidden graphics settings in PUBG Mobile?

In the main menu of the game, enter the code graphic 5 to the chat, then restart the game. An additional menu will appear with fine-tuning the rendering.

5. Check the device overheating

Overheating is a common cause sudden freezes of modern smartphones automatically crashing. data-i="142">(reduce performance) the processor at temperatures higher throttled (reduce performance) processor at higher temperatures 45–50°C. For example, Snapdragon 8 Gen 2 begins to limit frequencies already during 47°C.

How diagnose:

• 🌡️ Install a temperature monitoring application (for example, CPU Monitor or AIDA64).
• 🔥 If the processor temperature exceeds 50°C in the game - this is a critical indicator.
• 📦 Check whether the case is blocking the ventilation holes (relevant for ROG Phone or Black Shark).

How to reduce the temperature:

• 🧊 Remove case while playing.
• 🔋 Do not play while charging - this increases heating by 10–15%.
• 💨 Use a cooling pad (for example, Black Shark FunCooler Pro).
• 🔄 Reduce the screen brightness to 50–60%.

⚠️ Attention: If the smartphone gets hot up to 60°C and higher in simple games (for example, Among Us or Brawl Stars) - this is a sign of battery malfunction or thermal paste. Contact a service center.

6. Disable power-saving modes and background activity

Battery saving modes (Battery Saver or Ultra Power Saving) limit the performance of the CPU and GPU, which leads to lags. by Samsung Galaxy When the “Medium saving” mode is turned on, FPS in games drops by 20–30%.

What to do:

• 🔋 Disable battery saving mode in Settings → Device care → Battery → Power modes.
• ⚡ Add the game to the list of “Battery optimization exceptions” (at Xiaomi: Settings → Battery → Battery optimization → All applications).
• 📵 Disable automatic updating of applications in the background (Settings → Google → Auto-update applications).

For owners Xiaomi/Redmi/POCO:

Settings → Accessibility → MIUI optimization → Disable "Background restriction"

7. Problems with the Internet and game servers

If the game hangs at the loading stage or “slows down” online - the problem may be on the network. For example, in Call of Duty Mobile lags often occur due to high ping (more than 150 ms) or packet losses.

How to check:

• 📶 Switch from Wi-Fi to mobile data (or vice versa).
• 🌍 Use a VPN (for example, Cloudflare WARP or 1.1.1.1) if the game servers are blocked in your region.
• 📊 Check ping to the game servers through the app PingTools.

Optimal indicators for online games:

Parameter	Normal	Critical
Ping (ms)	20–80	> 150
Packet loss (%)	0–2%	> 5%
Speed (Mbps)	> 10	< 5

8. Extreme measures: resetting settings and flashing

If none of the above helped, radical methods remain. Reset to factory settings will delete all data, but often solves problems with software conflicts. A flashing via Fastboot or TWRP will help if system files are damaged.

How reset settings:

1. Make a backup copy of your data (Settings → System → Backup).
2. Go to Settings → System → Reset settings → Delete everything data.
3. After the reset, install only the necessary applications and check the game's operation.

When flashing is needed:

• 🔧 If the smartphone “boots” longer 5 minutes.
• 🐌 If lags appear even in the game menu.
• 🚨 If the logs (Settings → System → Error log) contain messages about system damage files.

⚠️ Attention: Flashing through unofficial firmware (for example, LineageOS) can lead to Loss of warranty unstable operation of the device. Use only official images from the manufacturer's website.

FAQ: Frequently asked questions about games freezing on Android

Why does the game only slow down on my smartphone, but it works fine for my friends?

Most likely, the problem is with specific processor model or version Android. For example, games on the engine Unity are often optimized for Snapdragon, but on Mediatek can slow down. Also check if your friends have the “Performance” mode enabled in the game settings.

Can a case cause games to freeze?

Yes, if the case fits tightly and blocks the ventilation holes (relevant for gaming smartphones like Asus ROG Phone or Black Shark). Also, some silicone cases impair heat transfer, which leads to throttling of the processor.

Does overclocking the processor help for games?

Overclocking (overclocking) through the engineering menu or applications like Kernel Auditor can give an increase in FPS by 5–15%but severely reduces the lifespan of the chip and increases the risk of overheating. On most modern smartphones, overclocking is blocked at the firmware level.

What games most often cause freezes in 2026?

According to GameBench, the top 5 "gluttonous" games for Android:

1. Genshin Impact (especially after update 4.5)
2. Call of Duty: Warzone Mobile (due to poor optimization for Mediatek)
3. Honor of Kings (high requirements for GPU)
4. Diablo Immortal (constant network lags)
5. PUBG Mobile (problems with anti-cheat on rooted devices)

Is it worth buying a gaming smartphone if games are slow on a regular one?

Gaming smartphones (for example, RedMagic 9 Pro or Black Shark 6) have active cooling, specialized chips and a screen with frequency 165 Hz, which gives a performance increase of 30–50%However, for most games, a mid-level flagship is enough. (for example, Samsung Galaxy S23 FE or Xiaomi 14).
