Frequently Asked Questions
How accurate vs Geekbench?
Browser-based ~70% accurate vs native Geekbench. Same trends — just different absolute numbers. Useful for relative comparison + tracking degradation over time.
Why does my old phone score low?
Phones throttle CPU when battery degraded or thermal-stressed. Score drop = symptom of aging hardware. Tracking your phone monthly shows degradation curve.
Different score on WiFi vs LTE?
Shouldn't be — this benchmark is local only (no network). Variation = thermal state of phone. Run cool, in airplane mode, after fresh restart for best score.
