Root Cause Analysis

What Causes Mobile Battery Draining Fast on apple-mobile iPhone 11?

Understanding the root cause helps our engineers perform a precise, lasting repair — not just a temporary patch.

Age & Cycle Wear

Li-ion batteries lose capacity after 300–500 charge cycles — a normal part of battery ageing.

Incompatible Charger

Non-genuine or mismatched chargers cause irregular charging and accelerate cell degradation.

Overheating

Gaming, heavy multitasking, or blocked vents raise internal temps and stress the battery cells.

Liquid Damage

Moisture or water ingress into the battery compartment causes cell corrosion and swelling.
