Swollen Phone Battery: What to Do

A swollen phone battery is a serious safety hazard. It occurs when gas builds up inside the battery casing, usually due to overheating, overcharging, or physical damage.

Immediate Steps

1. Stop Charging: Unplug the device immediately.
2. Do Not Press: Avoid pressing on the screen or back glass, as this could puncture the battery.
3. Seek Professional Help: Do not attempt to remove a swollen battery yourself.

Bring it to us for safe disposal and repair via our Battery Replacement Services.

Why batteries swell — and why it is urgent

Swelling happens when a lithium cell vents gas, usually after years of heat, daily fast charging, a cheap charger, or a tiny puncture from an earlier drop. Patna's summer heat and voltage fluctuations make it more common here than in cooler cities. A swollen cell is under pressure and one puncture away from catching fire, so it is not a "use it till it dies" situation — it is a same-day fix.

What not to do

• Do not keep charging it — that adds heat and pressure.
• Do not press, bend, or pierce the bulge to "let the air out."
• Do not throw it in normal waste — a damaged cell can ignite in the bin.
• Do not leave it in a hot room or car while you decide.

Power the phone off, keep it somewhere cool and open, and bring it in.
