Why Do Phone Batteries Swell?
Battery swelling is caused by gas build-up inside the lithium-ion cell. Here are the 6 most common triggers we see every day.
Charge Cycle Degradation
After 500–800 charge cycles, lithium-ion cells begin to break down internally. Gas builds up inside the cell casing as a byproduct of this degradation — causing the characteristic bulge.
Heat Exposure
Leaving your phone in a hot car, using it while charging, or heavy gaming sessions accelerate electrolyte breakdown inside the cell. Heat is the single biggest cause of premature battery swelling.
Overcharging / Faulty Charger
Using a non-certified charger that delivers incorrect voltage can cause the battery to overcharge. Excess energy converts to heat inside the cell, triggering gas production and swelling.
Moisture / Water Damage
Water ingress — even minor humidity over time — can corrode the battery terminals and trigger internal chemical reactions that produce gas, causing the cell to expand.
Physical Impact
A drop or crush that dents or punctures the battery casing can damage the internal separator between electrodes. This causes a short circuit inside the cell, generating heat and gas rapidly.
Manufacturing Defect
Rarely, a batch of cells leaves the factory with microscopic defects in the separator or electrode coating. These defects accelerate internal gas production even in relatively new phones.

Minor Swelling vs Severe Swelling — What's the Difference?
All swollen batteries need replacement — but the urgency and complexity of the repair depends on how far the swelling has progressed.
Minor Swelling
Needs replacement soon · Book within 24–48 hours
Minor swelling means the gas build-up is in early stages. The battery still needs to be replaced — but there's a short window to do it safely before it progresses. Stop charging the phone immediately.
- Very slight lift at the back panel edge — barely noticeable
- Phone still powers on and functions normally
- No visible cracking on the back glass or frame
- Swelling appeared recently (within days)
- No heat or smell coming from the device
- Battery health still shows above 70% in settings
Severe Swelling — Fire Risk
Urgent — bring in immediately · Do not charge
Severe swelling means the battery is under significant internal pressure. It can rupture, leak toxic electrolyte or catch fire. Do not charge it, do not leave it in a hot place, and bring it to us immediately.
- Back panel visibly bowed or cracked open
- Screen is being pushed up or separating from the frame
- Phone feels hot even when not in use or charging
- Burning smell or any discolouration near the battery area
- Phone randomly shuts off or won't power on
- Swelling has been present for weeks or is getting worse
