Solving iPhone Overheating
Primary Throttling Causes
Natlan's Pyro effects create constant particle rendering—baseline GPU loads 15-20% higher than Mondstadt/Liyue. Background apps compound thermal buildup. Ambient temps above 25°C reduce cooling efficiency—each 5°C increase cuts sustainable duration by 15-20 minutes.
Immediate Cooling Techniques
- Position cooling fan behind camera module: reduces temp 10-15°C
- Remove protective case: adds 10-15 minutes before throttling
- Reduce brightness to 50-70%: immediate thermal relief
Preventive Measures
- Clear cache every 2-3 hours: Settings > General > iPhone Storage > Genshin Impact > Offload App
- Enable Airplane Mode, re-enable Wi-Fi: disables cellular radio heat
- Maintain 8GB+ free storage: prevents swap file heat from storage operations
Environmental Factors
Room temp below 25°C extends gameplay 30-40%. Air-conditioned environments optimal. Avoid direct sunlight—elevates temp 5-8°C within minutes. Place on metal/glass surfaces for passive cooling; avoid fabric.
Eliminating Battery Drain
Highest Battery Impact Settings
