Samsung Galaxy S25 Ultra – Product Liability Lawyer

2026-06-04 – A Samsung Galaxy S25 Ultra smartphone has been reported to the U.S. Consumer Product Safety Commission (CPSC) after experiencing repeated battery swelling and extreme overheating, creating a fire and burn hazard. The incident, filed by a consumer who suffered minor burns, involves three consecutive battery failures and points to a potential design defect in the device's power management system.

Product Details

Brand Name: Samsung
Manufacturer: SAMSUNG TELECOM AMERICA (STA)
Model: Galaxy S25 Ultra
Retailer: Verizon
Incident Report Number: 6058264
Severity Type Name: First Aid Received by Non-Medical Professional
Severity Type ID: 7

Incident Overview

According to a CPSC SaferProducts.gov report (ID: 6058264), a consumer's Samsung Galaxy S25 Ultra experienced severe thermal runaway events over the course of a month. The original battery swelled, causing the back panel to separate. The consumer took the device to an authorized Samsung service partner, where the battery was replaced with an official OEM part. Within days, the replacement battery also swelled completely inside the chassis. A second replacement was performed, but the third battery is now actively swelling, bloating the chassis, and radiating extreme heat even when idle.

The device reached a measured temperature of 90°C (194°F), causing minor burns to the consumer's palm that took several days to heal. The consumer reported that the internal charging logic board or power management integrated circuit (PMIC) is fundamentally defective, delivering improper voltage and creating an ongoing fire, explosion, and chemical hazard. Despite reporting the issue to Samsung customer service over two weeks, the consumer stated that frontline support agents failed to escalate the issue, dropped communications, and closed active service tickets without resolution. The device cannot be safely operated or charged.

Safety Concerns

Immediate Dangers: Lithium-ion battery thermal runaway can lead to rapid overheating, fire, and even explosion. In this case, the phone reached 194°F, hot enough to cause first-degree burns on contact. If the battery ruptures, flammable electrolyte can ignite, posing an immediate fire hazard to the user and nearby surroundings.

Long-Term Risks: Repeated battery swelling indicates a persistent electrical fault. Continued use or charging of the device could trigger a catastrophic failure, including a lithium fire that is difficult to extinguish. The defect may also shorten battery lifespan or cause internal short circuits over time.

Warning Signs: Consumers should watch for unusual heat, bulging of the phone's chassis, back panel separation, or hissing sounds from the device. Any of these symptoms suggest battery swelling and imminent thermal runaway.

Who Might Be Affected: The primary risk is to the device user, but bystanders, especially children or pets, are also vulnerable if the device is left unattended. The fire and chemical hazard extends to anyone in the same room, particularly if the phone is charging on a flammable surface.
