Why do cellphones explode


    Why do cellphones explode

  • 1 A break in battery material

    A break in the compacted battery material can cause an internal short circuit. This short circuit can then lead to swelling or explosions.

  • 2 Dropping the phone

    Dropping the phone might cause a break in the battery material, which could in turn lead to explosions.

  • 3 Poorly manufactured batteries

    Poorly manufactured batteries or cheap ones can contain small particles that might lead to a short circuit, which causes explosions. Those particles might be present as a result of poor quality of the battery. See also why your smartphone isn't charging.

  • 4 Excessive heat

    Excessive heat can lead to an internal short circuit within the battery and might lead to explosions. The Samsung Galaxy Note 7 had a battery problem related to overheating of the phone, and this is why it used to explode while being charged.

  • 5 Over-charging

    Over-charging can damage the phone's battery, as the batteries receive more heat than they could handle. As the batteries overheat, they might get damaged and so become more likely to explode. See why smartphones are so popular.

  • 6 Thermal runaway

    Too much heat reaching only one area of the battery can cause a chain reaction that leads to more heat, Thermal runaway, which could in turn lead to an explosion.

  • 7 Battery has no safety mechanism

    High quality batteries have safety mechanisms that prevent thermal runaway from happening. Poor quality batteries can fail to stop the chain reaction leading to the explosion.

  • 8 Overheated processor

    If the processor of the phone generates too much heat and if this heat teaches the battery, it might become harder for the battery to lose heat and so the probability of an explosion might rise. See why smart phones are getting bigger.

  • 9 Incompatible charger

    Using an incompatible charger might lead to explosions since the charger might lead to overcharging. If the battery failed to stop the overcharging, an explosion might happen. See also why your phone isn't charging.

  • 10 Fast charging

    If the fast charging charger is not fully compatible with the battery, it might lead to a short circuit. Fast charging can lead to the formation of needle-like structures called dendrites inside lithium batteries. Those dendrites can cause a short circuit, which might lead to explosions.

  • 11 High voltages

    The electrolytes inside batteries are not very stable. When batteries use high voltage, the electrolytes might combine with other elements; thus short circuiting the battery.

  • 12 Using a case that traps heat

    If the case you are using for the phone is trapping heat, you might risk an explosion since the heat can hardly leave the battery. See why using a phone before sleeping is bad.

  • 13 Direct sunlight

    Direct sunlight can overheat the phone; thus leading to an excessive heat problem that might cause damage to the battery. The damaged battery can explode later on.

  • 14 Puncture in the battery

    A puncture in the battery can result in a short circuit. The puncture can happen as a result of dropping the phone or putting a pressure on the battery.

  • 15 Very thin batteries

    If the batteries are very thin and if they are not designed to properly sustain pressure or other types of mechanical damage, they can easily get damaged; thus creating the risk of a short circuit.
