How long does a smartphone charger last?
The average lifespan of a typical smartphone charger (adapter or cable) is approximately 2 to 3 years . However, this is only a reference value, and lifespan can vary greatly depending on frequency of use , handling , and charging environment (high temperature , humidity, etc.).
Cheap 100 yen store products and non-certified products in particular have a short lifespan and pose a risk of overheating and electric shock . On the other hand, genuine products that have Apple's MFi certification or PSE certification are of high quality and can be used for a relatively long time.
When should you replace your smartphone charger?
Even if your battery life is still not over, we recommend replacing it early or checking it regularly in the following cases:
- If used daily , check once every 1 to 2 years
- If you are using an older model that does not support fast charging , consider switching to a model that supports the latest standard .
- Frequent plugging and unplugging, bending , and pulling of the cable → Deterioration progresses quickly , so it is safe to replace it early.
- Lithium-ion batteries in particular handle high voltages, so a malfunction in the charger can cause damage to the smartphone itself or even a fire , so regular inspection and replacement are important from a safety standpoint .
What are the signs to replace?
If you notice any of the following signs, your charger is likely nearing the end of its life :
- Charging speed has become extremely slow
- Contact is unstable and charging stops depending on the angle
- Abnormal heat generation during use
- Physical damage such as broken wires , torn insulation , or deformation
- Signs such as a burnt smell or discoloration
In particular, heat or a burning smell can lead to a fire or electric shock risk , so stop using the product immediately.
