Five Unity settings that quietly wreck mobile performance

Texture compression, batching, occlusion and the three quality tiers that eat your frame budget before you've written a line of code.

Most mobile performance problems we audit are not caused by clever code — they're caused by default settings.

1. Texture compression left on 'automatic' can silently pick a format your target GPU hates.

1. Dynamic batching off means thousands of draw calls you never see in the editor.

1. Quality tiers copied from a desktop template will burn battery and throttle the device within minutes.

Fix the defaults first. Profile second. Optimise third — and only what the profiler actually flags.
