How to Fix Clash of Clans
Lag

If Clash of Clans is lagging, stuttering, or rubber-banding, follow these steps in order. First confirm the lag isn't server-side by checking the live status page — if dozens of players are reporting issues, Supercell's servers are the cause.

Step-by-Step Fix

1
Switch between Wi-Fi and cellular
If Clash of Clans is lagging on Wi-Fi, switch to cellular data to test. If cellular is better, your Wi-Fi router may be congested. If Wi-Fi is better, your cellular signal is the bottleneck.
2
Connect to 5GHz Wi-Fi
Switch your phone to your router's 5GHz network instead of 2.4GHz. The 5GHz band has less interference from neighboring devices and significantly lower latency for Clash of Clans.
3
Disable background apps
Close all other apps running in the background before playing Clash of Clans. Background apps on mobile consume both network bandwidth and RAM, causing Clash of Clans to lag and disconnect.
4
Disable VPN
Supercell's servers actively reject connections from VPN IP addresses, returning a "Connection Lost" error that looks identical to a server outage. VPN apps with auto-connect features are a frequent silent culprit — you may have one active without realizing it. Open your VPN app and disable it completely (not just pause) before launching CoC.
5
Lower Clash of Clans graphics settings
In CoC settings, reduce the graphics quality slider. On older Android devices, the game's terrain rendering and particle effects during attacks — explosions, spell animations, multiple troop movements — are the primary source of frame drops. Lowering graphics reduces processing load during combat and can also prevent mid-attack disconnects caused by the device overheating.
6
Restart your router
Unplug your router for 30 seconds and plug it back in. Over time, routers accumulate stale connection tables that can cause latency spikes in mobile games. A reboot clears these and often resolves persistent CoC lag.
Is it server-side?
Check real-time player reports — if reports are spiking, it's on Supercell's end, not yours.

Frequently Asked Questions

Why is Clash of Clans lagging so much?

CoC lag is almost always a network issue rather than device performance. Check your Wi-Fi signal strength, switch to 5GHz, disable VPN, and close background apps. If lag persists on both Wi-Fi and cellular, the issue is likely on Supercell's servers.

Why does Clash of Clans lag during attacks?

Attack lag is caused by your device sending rapid position updates during troop movements while simultaneously receiving damage updates from Supercell's servers. A weak or congested network connection can't keep up with this traffic. Switch to 5GHz Wi-Fi and close background apps.

Why does Clash of Clans lag only on my phone but not on my tablet?

Device-specific lag usually indicates a hardware issue with that device — insufficient RAM causing the OS to throttle background processes, or a weaker Wi-Fi antenna in the phone receiving a lower-quality signal. Try the tablet's network and compare ping values.
