Just started playing Genshin Impact on my iPhone 15 and I can barely get through two hours before it dies. The graphics are nice but is there any way to make it less demanding? My mate's phone handles it fine so it's not just the game.
Genshin Impact is one of the most GPU-intensive games out there, so your iPhone 15's battery gets hammered trying to render all those detailed environments and characters. Try lowering the graphics settings to medium or low, turning off motion blur, and reducing the frame rate cap - that should get you closer to the 2+ hours you're looking for.
The game's pushing your phone crazy hard, so turn off motion blur and lower the frame rate cap to 30fps in settings - that alone makes a massive difference! Your mate might just have better battery health or keeps their phone cooler while playing.
