January 30, 2026 – A serious product safety incident involving an Apple iPhone 16 Pro Max has been reported, highlighting potential risks associated with lithium-ion battery failures, particularly during air travel. The device reportedly experienced significant battery swelling while at altitude on a commercial flight, leading to severe separation of the device’s components and raising concerns about thermal runaway and fire hazards.
Product Details
Incident Overview
The incident occurred on December 28, 2025, during a commercial air travel departure from Fort Lauderdale (FLL). According to the report, an Apple iPhone 16 Pro Max began to physically swell while the aircraft was at altitude. This swelling was severe and clearly visible, causing a pronounced separation between the rear glass panel and the device frame, observable even with the phone remaining in its protective case.
The device owner noted a documented history of problems with this particular iPhone 16 Pro Max, including overheating, unexpected restarts, unstable charging, and camera focus issues since its initial use. This was a replacement device, as the original iPhone purchased by the consumer had also been replaced shortly after purchase due to other defects. The recurrence of serious issues, specifically battery expansion, in the replacement device points to a significant lithium-ion battery safety failure. The consumer expressed strong concerns about the device’s safety for use or transport, especially given imminent additional air travel plans.
Safety Concerns
The reported battery swelling in a lithium-ion powered device like the iPhone 16 Pro Max presents several critical safety concerns:
- Immediate Dangers: Battery swelling is a strong indicator of internal chemical instability, which can lead to thermal runaway. Thermal runaway is a rapid, self-sustaining increase in temperature that can result in fire or explosion. The risk of such an event is particularly heightened in confined environments like an aircraft cabin, where resources to mitigate a battery fire are limited, and smoke inhalation or fire could endanger all passengers and crew.
- Long-Term Risks: Even if an immediate thermal event does not occur, a swollen battery indicates a severely compromised device that should not be used. Continued use or charging could exacerbate the internal damage, increasing the likelihood of a future, potentially more severe, incident.
- Who Might Be Affected: The primary individual affected is the device owner, who faces direct risk of injury from a fire or explosion. In an aircraft setting, however, all passengers, flight crew, and the integrity of the aircraft itself are at risk. In a home or office, surrounding individuals and property are also vulnerable.
- Property Damage Potential: A battery fire or explosion can cause extensive damage not only to the device itself but also to surrounding personal belongings, furniture, or the interior of a vehicle or aircraft. The documented history of other malfunctions (overheating, charging instability) prior to the swelling further suggests a systemic issue that could lead to multiple failure points.
What Consumers Should Do
If you own an Apple iPhone 16 Pro Max or any electronic device exhibiting similar symptoms, it is crucial to take immediate precautions:
- Stop Using Immediately: Power off the device and cease all use, including charging.
- Do Not Charge: Under no circumstances attempt to charge a device with a swollen battery. This significantly increases the risk of fire or explosion.
- Isolate the Device: If possible, place the device in a cool, dry, non-flammable location, away from combustible materials. Do not puncture or attempt to open the swollen battery.
- Do Not Travel by Air with a Swollen Device: Airlines and aviation authorities prohibit the transport of damaged or recalled lithium-ion batteries that pose a safety risk. A device with a visibly swollen battery is a clear fire hazard and should not be brought onto an airplane.
- Check Your Device: Regularly inspect your iPhone or any other smartphone for signs of battery swelling. Look for unusual bulges, a separating screen or back panel, or a soft, spongy feel to the device.
- Contact the Manufacturer: Immediately contact Apple Support to report the issue and seek their guidance on safe handling and replacement.
- Report the Incident: File a report with the U.S. Consumer Product Safety Commission (CPSC) at saferproducts.gov to help track incidents and inform potential safety actions. For incidents involving air travel, consider also reporting to the Federal Aviation Administration (FAA).
Manufacturer’s Response
The manufacturer’s official response to this specific incident report is currently unknown. However, the consumer indicated that Apple Support had acknowledged these issues through chat and phone communications prior to the incident, though a timely resolution was not provided despite the consumer’s imminent air travel.
