If your phone's screen is lifting, the back is bulging or it rocks when you lay it flat, the battery could be swollen. It's easy to ignore, but a swollen battery is a warning sign you shouldn't put off.

Why do phone batteries swell?

Phone batteries are lithium-ion. As they age, or if they're damaged, overheated or charged with poor-quality chargers, gas can build up inside the battery and make it puff up.

Warning signs to look out for

• The screen lifting away from the frame, or a gap along the edge
• The back of the phone bulging or cracking
• The phone rocking or spinning when laid on a flat surface
• The phone getting unusually hot
• The battery draining very quickly or the phone shutting down suddenly

Why a swollen battery is dangerous

A swollen battery is under pressure. If it's punctured, bent or overheated, it can catch fire or release harmful fumes. The swelling can also crack your screen and damage parts inside your phone, turning a battery job into a bigger repair.

What to do if you think your battery is swollen

• Stop charging it straight away
• Don't press on it, bend it or try to push the screen back down
• Never pierce it or try to remove the battery yourself
• Keep it away from heat and don't leave it on your bed or sofa
• Don't put it in the household bin, as damaged batteries can start fires
• Bring it to a repair shop as soon as you can
