Why Do Phone Batteries Swell?
Lithium-ion batteries swell due to gas buildup inside. Common causes:
1. Overcharging
- Leaving your phone plugged in overnight degrades the battery.
2. Heat Exposure
- Hot cars, direct sunlight, or fast charging accelerate swelling.
3. Physical Damage
- Dropping your phone can puncture the battery.
4. Old Age
- Batteries over 2–3 years old are high-risk.
Did You Know?
- A swollen battery won’t go back to normal—it must be replaced!
6 Danger Signs of a Swollen Battery
1. Bulging Back or Screen
- The phone won’t lie flat on a table.
- iPhones: Screen lifts from the frame.
- Androids: Back cover pops open.
2. Creaking or Cracking Sounds
- Pressure from the battery warps the phone’s frame.
3. Overheating for No Reason
- Gets hot even when not in use.
4. Fast Battery Drain
