Incident Overview

According to a report filed with the CPSC SaferProducts.gov database (Report ID 6046220), a consumer experienced a battery failure with their Samsung S23 Ultra shortly after installing a software update in April 2026. The consumer reported that immediately after the update, the battery began draining rapidly, requiring charging four times a day compared to the previous once a day. The device also began overheating. Two weeks later, the consumer noticed the back of the phone separating from the frame due to a swollen battery, a condition known as battery pillowing.

The consumer contacted Samsung for assistance but was initially told they would have to pay for the repair, despite attributing the damage to the software update. After escalating the issue to the CEO’s office, the consumer was offered a one-time repair, which they declined, requesting a replacement phone due to safety concerns. The consumer reported being unable to transfer data to an older phone and noted that the device becomes extremely hot when powered on, making them uncomfortable keeping it in their home due to fire risk. The report also references other users experiencing similar battery problems after the April 2026 update, suggesting a pattern.

Safety Concerns

Immediate Dangers: A swollen lithium-ion battery can undergo thermal runaway, a chemical reaction that releases intense heat and flammable gases. This can lead to the battery catching fire or exploding, posing an immediate burn hazard to the user and anyone nearby.

Long-Term Risks: Continued use of a device with a swollen battery increases the risk of catastrophic failure. The battery’s internal structure is compromised, and the pressure buildup can cause the phone’s casing to rupture, potentially releasing toxic chemicals and causing further damage.

Warning Signs: Key indicators of battery failure include rapid battery drain, overheating, physical swelling of the device (such as the back panel separating), and difficulty powering on the device. These symptoms should prompt immediate cessation of use.

Who Might Be Affected: The primary risk is to the device owner and anyone in close proximity, such as family members or coworkers. The hazard is particularly concerning if the device is used or stored in enclosed spaces like pockets, bags, or near flammable materials.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If your device shows signs of battery swelling, overheating, or rapid discharge, power it down and stop using it. Do not attempt to charge it, as charging can accelerate the failure.

Do Not Attempt Repairs: Do not try to remove the battery yourself. Puncturing a swollen battery can cause a fire or chemical burn. Leave handling to professionals.

Preserve the Product: Keep the device in a safe, non-flammable area (e.g., on a concrete surface or in a metal container) away from children and pets. Preserve it as evidence in case of future legal action.

Document the Incident: Take photos of the damage, save all communications with the manufacturer, and record the date and details of the incident. This documentation is critical for any potential claim.

Report to the CPSC: File a report with the CPSC at SaferProducts.gov to help identify patterns and inform other consumers. Reference Report ID 6046220 if applicable.

Check for Recalls: Visit CPSC.gov to check if there is a recall for your device model. Even without a recall, be aware of potential safety issues.
