Hotspot Thermal Deep Analysis - Smartphone Overheating
🔥 Deep Thermal Analysis: Smartphone Hotspot Overheating System
Mode hotspot adalah salah satu kondisi beban tertinggi pada smartphone modern karena mengaktifkan dua modul sekaligus:
radio receiver (4G/5G) dan WiFi transmitter secara bersamaan.
💡 Studi internal menunjukkan konsumsi daya meningkat 180%–250% saat hotspot aktif dibanding idle normal.

📌 9. System Insight
💡 Hotspot bukan sekadar fitur jaringan — tetapi mode “dual-radio compute load” yang membebani CPU, modem, dan battery secara simultan.
✔ Panas bukan bug — tapi hasil desain hardware load tinggi
✔ Kerusakan terjadi jika dibiarkan di suhu >60°C terlalu lama
✔ USB tethering adalah metode paling stabil secara termal
