Watch electricity flow from your charger → through protection → into the battery → then split into tiny voltages for CPU, RAM, camera, and everything else!

💡 Super Simple: Think of your phone like a water park! The charger is a big water pipe (5V). OVP is the lifeguard. Charging IC fills the water tank (battery). Power IC is the water tank with many small taps (1.8V, 2.8V, 0.9V). Each tap gives just the right water to each ride (phone part)!

📋 How Power Flow Works (Step by Step)

🔌 Charger
🔌 USB Port
🛡️ OVP IC
🔋 Charging IC
⚡ VBAT Battery
🔋 VPH_PWR
🏭 Power IC
⚡ Different Voltages
🤖 CPU, RAM, Display, Camera

💧 Think of Power IC as a Water Tank!

It takes one big power (VPH from battery) and gives small powers to all parts like different taps! 🚰

Big pipe (4V) → Water Tank (Power IC) → Small taps (1.8V, 2.8V, 0.9V) → Each phone part drinks what it needs!

VBUS - 5V from charger
OVP - Voltage protection guard
Charging IC - Battery charging chef
VBAT - Battery storage (3.7-4.4V)
VPH_PWR - Main power highway
Power IC - Splits power to all parts
1.8V LDO - Small power for sensors
2.8V LDO - Medium power for camera
0.9V LDO - Tiny power for CPU core
CPU - The brain of the phone
RAM - Short-term working memory
Thermal IC - Temperature police
