Delays in Brawl Stars on Xiaomi smartphones are a common problem that spoils the gaming experience even on powerful devices, and can be due to both the game’s settings, system settings, or connectivity issues. Unlike PCs, where lags are often associated with hardware, mobile devices are to blame for usually unoptimized background processes, MIUI limitations, or unstable Wi-Fi/mobile data.
In this article, we will look at the unique reasons for Xiaomi lags in Brawl Stars that are not found on other Android devices — for example, aggressive memory management in MIUI or hidden power saving settings for games. You will learn how to diagnose the problem, which parameters to check first, and what to do if standard tips (like rebooting a router) do not help.
1. Internet speed check: basic test before settings
Before digging into Xiaomi's settings, make sure the problem isn't on the provider or router side. lags in Brawl Stars manifest when ping is above 100ms or download speeds are below 5Mbps.
- 📱 Use Speedtest by Ookla (not the web version!): it measures ping more accurately on mobile networks.
- 🔄 Run the test 3 times in a row and write down the averages. If ping jumps from 50 ms to 300 ms, there's a problem with the network.
- 🌐 Compare the results on Wi-Fi and mobile Internet. 4G/5G No lags - the router's fault.
If the speed is consistently low:
⚠️ Note: Xiaomi with MediaTek processors (e.g. Redmi Note) 11) There are often problems with the Wi-Fi module 5 GHz. Try to manually switch to range 2.4 GHz in router settings – this can reduce ping on 20-30%.
| Parameter | Norm for Brawl Stars | Critical significance |
|---|---|---|
| Ping (ms). | < 80 | > 150 |
| Download speed (Mbps) | > 10 | < 3 |
| Packet losses (%) | 0 | > 1 |
| Jitter (MS) | < 30 | > 50 |
2. MIUI optimization for games: hidden settings
Xiaomi aggressively optimizes background processes, which can lead to microfreezes in games. MIUI has hidden settings that affect the performance of Brawl Stars:
- Turn off MIUI Optimization: Go to Settings → About Phone → MIUI Version (tap 7 times to activate Developer Mode). Then in Settings → Additional → For Developers, find Background Limitation and select Unlimited.
- Add Brawl Stars to Game Turbo: Open Settings → Annexes → Gaming turbo, add Brawl Stars to the list and activate options: 🔋 "High priority of the network" 📵 "Disable notifications" 🔄 "Clearing memory on exit" (turn off!)
For models on the Snapdragon 8 Gen 1/2 (for example, Xiaomi 12 Pro, Redmi K50 Gaming) additionally:
Disable "Thermal Throttling" in the developer settings |
Set FPS limit to 60 in Brawl Stars| settings
Activate Performance Mode in MIUI Battery Saver|
Turn off Adaptive Brightness during the game-->
On Xiaomi with MediaTek processors (Helio G96, Dimensity 900, etc.), lags are often associated with Wi-Fi drivers. If after all the settings the problem remains - try updating the firmware of the Wi-Fi module through Settings → Wi-Fi → Additional → Update the driver (not available on all models).
3. Set up router to reduce ping
If the lags only appear on Wi-Fi, the problem may be in the router.
- 📶 Wi-Fi Channel: Manually Set up Channel 6 or 11 for 2.4 GHz (they're least congested). 5 GHz select channels 36-48 or 149-165.
- 🔒 Channel width: For 2.4 GHz, 20 MHz, for 5 GHz, 40 MHz (wider channel) = more).
- 🔄 QoS (Quality of Service): Enable and prioritize IP-Your Xiaomi address (find it in Settings) → Wi-Fi → Devices).
- 🛡️ Safety: Only use WPA2-AES or WPA3. TKIP or mixed modes increase ping.
For owners of routers Xiaomi Mi Router:
Enter 192.168.31.1 → Log in → Go to Advanced Settings → QoS → Add a rule for UDP- port 9339 (used by Brawl Stars).⚠️ Note: If you have a dual-band router and Xiaomi is constantly reconnecting between 2.4 GHz and 5 GHz, turn off the Smart Connect (or Band Steering) function in the router settings.
4.Mobile Internet: APN settings and network priority
On mobile data, the lags in Brawl Stars are often associated with suboptimal APN settings or operator restrictions.
- Check it out. APN: Go to Settings. → SIM-maps and mobile networks → Access points (APN). Make sure your operator profile is active, if not, create it manually (options can be found on the operator's website).
- Forced to turn on. 4G/5G: B Settings → SIM-map → Preferred network type select only LTE (for 4G) or 5G/4G/3G (Auto mode can lead to switching to slow networks.
- Turn it off. VoLTE/VoWiFi: In some regions, these features conflict with game traffic. → SIM-map → Challenges.

5.Cache cleanup and Brawl Stars data
Game failures are often associated with damaged cache or outdated data.
- Cache Cleanup: Go to Settings → Applications → App Management → Brawl Stars → Storage → Clear the cache.
- Data reset (if the cache didn’t help): In the same menu, click Clear Data. Attention: this will delete all game settings, but will not affect the associated Supercell ID account.
- Reinstall the game: Remove Brawl Stars, restart the phone and reinstall from Google Play.Do not download APK from third-party sources - this can aggravate the lags.
After data clearing:
💡
Before you first start the game after resetting data, connect to Wi-Fi and wait for all resources to be fully loaded (the screen will show the inscription "Download completed"). This will prevent lags due to loading textures during the battle.
6. Alternative methods: VPN and DNS
Sometimes the lags are caused by an unstable route to Supercell servers, in which case:
- 🌍 Change of change DNS: Use 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google). How to set up: Go to Settings → Wi-Fi → Additionally. → Settings IP → Static, in the field. DNS 1 enter 1.1.1.1, in DNS 2 - 1.0.0.1. Save and reconnect to the network.
VPN for stable ping:
ProtonVPN
Warp
increase
Mudfish
For Xiaomi users in Russia and CIS:
💡
The best servers to connect to Brawl Stars are Frankfurt (Germany) or Amsterdam (Netherlands). Avoid servers in Asia - even with low ping, packet losses are more common.
7. Hardware problems: overheating and battery
On Xiaomi devices with a worn-out battery (capacity below 80%) or overheating of the processor, MIUI automatically limits performance, causing lags.
- 🔋 Battery status: Install AccuBattery and check for wear and tear. If the capacity is below 75%, replace the battery.
- 🌡️ Overheating: Use it during the game CPU Monitor for temperature monitoring, if it exceeds 65°C - the game will lay.
- 🛠️ Thermopaste: On older models (Redmi Note 8 Pro, POCO F1) dried thermopaste can cause trottling. The solution is a service center replacement.
