Fix My Mobile helps Samsung users across Australia identify swollen batteries, protect data, and replace unsafe parts quickly. Our technicians inspect lithium-ion batteries, isolate damaged components, and restore safe operation. We check Galaxy battery health, assess temperature history, and advise the safest next step. If your device shows swelling or unexpected shutdowns, stop using the device and book a battery check-up with our repair service today.
How to identify a swollen battery safely
A swollen lithium-ion battery may push the screen up, open a gap in the frame, or cause shutdowns and shorter battery life. Check the battery by looking for lift, creaks, or a wobbly touch when pressing the screen corners without force.
Common signs appear after extended use or storage at temperatures outside of a certain range. The device may rock on a flat desk, the back cover may not sit flush, or the display may show colour distortion near edges. You might notice the battery could drain unusually fast, then trigger an unexpected shutdown. Example: a Galaxy placed in a hot car on a summer day later shows a slight frame gap and random reboots; both point to swelling.
What to look for
- Screen lift or frame gaps
- Rocking on a flat surface
- New clicking or creaking sounds
- Sudden battery life drops and shutdowns
First steps if the battery is swollen
Power down, isolate the device, and avoid charging to prevent further damage; place your device in a cool area and seek professional help promptly.
If the battery is swollen, avoid pressing on the screen or back. Do not try to remove the battery without training or tools, as punctures risk fire. Let the device adjust to the optimal usage temperature by moving it to a shaded, ventilated place. If you smell a sweet, solvent-like odour or see the case opening, isolate the device on a non-flammable surface and keep it away from children and pets. Example: after noticing a lifted display, a user powers off, avoids charging, and brings the phone in for inspection the same day.
Immediate actions
- Power off and do not charge
- Do not press on the case
- Isolate on a hard, non-flammable surface
- Book a time for a battery check-up
Why lithium-ion batteries swell over time
Lithium-ion batteries may swell when gas builds inside the cell due to age, high heat, deep depletion, or long periods at full charge or empty.
Batteries are consumable parts; chemistry changes under stress. Exposure to extreme temperatures accelerates battery deterioration and may lead to internal gas formation. Leaving a device with a depleted battery for a long period can also stress cell chemistry. Similarly, extended use or storage at temperatures like a hot car or below-zero temperatures during wintertime can exacerbate battery performance and may lead to unexpected shutdowns. Example: a device left fully charged in a hot car shows swelling within weeks.
Factors that increase risk
| Factor | Effect on battery life |
|---|---|
| Heat/cold extremes | Faster deterioration |
| 0% or 100% for long | Chemistry stress |
| Age/high cycles | Gas formation risk |
| Physical damage | Internal shorts |
Care and maintenance for better battery health
Use temperature-aware habits, authentic Samsung charging cable and plug, and sensible storage to minimise battery deterioration and damage.
Always use an authentic Samsung charging cable and Samsung charging cable and plug to avoid damaging the battery. Avoid exposure to extreme temperatures; optimal battery usage is typically room temperature, and extreme temperatures will activate the device’s safeguards. The battery management system limits charging if the temperature goes outside of a certain range to protect the battery. For storage, charge to roughly half, power down, and store your device in a cool, dry place.
Everyday battery care
- Keep out of hot cars and freezers
- Use or place your device in moderate temps
- Run device diagnostics for battery health
- For storage, aim ~40–60% charge
When battery replacement is the right call
If the battery is swollen or shows safety risks, replacement by trained technicians is the safest option to prevent unexpected failures.
Fix My Mobile provides device’s battery replacement guidance during intake, then completes replacement with tested parts and safety checks. We inspect the battery management system logs where available, test charge/discharge, and verify the frame and sealing after repair. Example: a device with shutdowns and a lifted screen receives a new battery and frame adhesive; post-repair tests show stable voltage and normal thermal behaviour.
Replacement is recommended if
- The battery is swollen or smells odd
- The screen lifts or the back won’t close
- Charging is limited to protect the battery
- The device shows repeat shutdowns
How to judge urgency and stay safe
Treat swelling, gaps, or heat as urgent; isolate the device and avoid charging, then arrange inspection the same day to prevent unexpected damage.
Time matters. Chemical changes may accelerate if a device is left with a depleted battery or kept hot. If you see the case open, feel heat while idle, or the device shuts down suddenly, act immediately. If you only suspect battery performance issues without visible swelling, reduce load, let the device cool, and schedule diagnostics soon. Example: a phone warms during charging and caps current; charging will be limited by safeguards, signalling a need for checks.
Urgency signals
- Visible swelling or frame gaps
- Hot spots while idle or charging
- Repeated shutdowns and shorter battery life
- Charging limits or warnings
Next steps in phone repair with Fix My Mobile
Start with diagnostics; we confirm swelling, check the Galaxy battery, and advise repair options that protect your data and return safe function.
Our technician will check the battery health, run device diagnostics, and inspect the enclosure. If replacement is needed, we’ll quote clearly and schedule same-day where possible. We can also address related issues, like a stressed charging port from case expansion. If you prefer, contact Samsung Australia or a Samsung Support Centre for advice on coverage; limited warranties vary by program and region.
