Wireless Charging Guide

Most charging problems aren't caused by the charger — they're down to heat, alignment, and power stability. This guide explains why and how to fix it.

How wireless charging works

Wireless charging transfers energy through an electromagnetic field between two coils. Because energy travels through the air instead of a metal contact, some power is lost as heat. Important consequence: charging speed is limited mainly by temperature — not wattage.

Why the phone heats up when charging

Heating is caused by a combination of three factors: coil misalignment, unstable power source, and background use. The phone protects the battery by slowing or stopping charging at 80%. This isn't a fault — it's battery protection.

The 80% charge limit explained

Modern phones slow charging after 70–80% because lithium batteries degrade faster when charged at high voltage and temperature at the same time. Charging stopping doesn't mean a faulty charger.

Wireless vs wired charging

Wired: higher peak power, sensitive to cable quality, wears connectors. Wireless: lower peak power, more consistent daily charging, less connector wear. In daily use, consistency matters more than peak power.

Charging on the go

Planes, cars, trains, cafés, and hotels cause charging issues because voltage varies and movement repeatedly breaks the coil alignment. That's why phones often run out even when plugged in on the road.

Battery health: what actually damages it

The battery's worst enemies: heat, full 0–100% cycles, charging while navigating, and poor alignment in wireless charging. Not harmful: overnight charging, partial charging, top-up during the day.

When a magnetic charger helps

A magnetic charger solves the three most common wireless charging issues: keeps alignment stable, prevents cable wear, and stabilises travel charging.

Recommendation

Stable charging on the go. Magnetic grip, compact size, travel-friendly.

Choosing capacity

Bigger isn't always better — weight affects usability more than capacity.
