Per Apple Metal + Android Vulkan docs, BATTERY drain on mobile is dominated mostly by which subsystem during GPU-heavy gameplay?
ACPU cores idle waiting for the GPU only
BAudio DSP playing back music continuously alone
CNIC sending small location packets occasionally
DDisplay + SoC GPU together (with throttling effects)
Answer & Solution
Correct answer: D. Display + SoC GPU together (with throttling effects)
Mobile vendor docs + battery profiling research: bright OLED + sustained GPU load are the top drains. Engines target 30 FPS to halve GPU duty and extend playtime.
