Phone not charging – what is the cause?

Before you think about a new phone: the cause is often small – a broken cable, lint in the port or a tired battery. Here is how to find out.

What you can check yourself

When the charging port needs replacing

If the phone only charges when you hold the cable at a certain angle, the plug sits loosely or it no longer charges with any cable, the charging port is usually worn or damaged. Often a professional cleaning is enough first – we check that for you.

A charging port replacement costs from CHF 59 for iPhone and from CHF 79 for Samsung. If the phone charges but drains quickly, the battery is more likely the cause.

Frequently asked questions

Can a charging port be cleaned?
Yes. Lint from your pocket is often the cause. We clean the port carefully and only replace it if it is really faulty.
How long does a charging port replacement take?
For most models 30 to 60 minutes.
How can I tell whether the battery or the port is to blame?
If the phone does not charge at all or only at a certain angle, it is usually the port. If it charges normally but does not last long, it is more likely the battery.
