Why iPhone battery decline

Lithium-ion lifecycle:

• 500 cycles → ~80% capacity
• 1000 cycles → ~70% capacity
• 1 cycle = 100% drain (can be split: 100→50 + 100→50)
• Battery degrade từ ngày đầu tiên

Factors accelerate decay:

• Heat exposure (above 35°C)
• Deep discharge (0%)
• Constant 100% storage
• Fast charging frequent
• Charge cycle high frequency

12 settings chi tiết

FAQ chi tiết

Sạc qua đêm có hại pin không?

Modern iPhone Optimized Battery Charging giúp slow charge past 80%. Mostly safe, but ideally 80% limit + unplug when reach.

Pin 100% có vấn đề?

Short-term OK. Long-term constantly at 100% degrades faster. Aim 20-80% cycle.

Wireless charging có damage pin?

Slight more heat than wired = slight more degradation. Convenience worth it most. Don't use for fast charging frequently.
