Why a battery fails before a phone does

A phone battery wears out before the rest of the phone does. Heat is the biggest enemy, so a hot pocket or a charging case left in the sun does real damage over time.

If your phone switches off at 20%, swells, or drains in a few hours, the battery needs replacing. It's a quick fix that gives the phone new life.

Signs the battery is failing

A battery nearing the end does not just lose charge faster. Watch for the phone switching off at twenty percent, taking long to charge, or feeling warm while idle. A slightly swollen back cover is also a sign, and in that case stop using it and bring it in before the swelling cracks the screen.

A battery that swells is not something to wait on. Stop charging it immediately and bring the phone in, since a swollen cell can crack the screen or damage the case around it.

Replacing a worn battery is usually the cheapest way to make an old phone feel new again. A fresh battery brings back the standby time and stops the random shutdowns, often for a fraction of the cost of a new phone. Most of our battery swaps are done within the hour, tested before we hand it back.

Know your warning signs

If your phone needs charging twice a day when it used to manage one, or switches off well above zero percent, the battery is already on its way out.

When to bring it in

Do not wait for the phone to die completely. A battery left to run flat again and again wears out faster, so book it in while it is still holding some charge.

Our battery replacements come with a six month guarantee, so if anything feels off after the swap you can bring it straight back. No charge for a follow up visit if the part turns out faulty. We only fit batteries that meet the original specification, never generic cells that drain fast or swell within months.
