Charging your smartphone overnight is a routine most of us trust to be safe. But a recent incident involving a Samsung Galaxy S25 FE that exploded while charging near a bed has stirred concern and questions about smartphone battery safety.
- A Galaxy S25 FE reportedly exploded during overnight charging, causing minor injuries and bedroom damage.
- The phone was connected to a third-party 20W USB-PD charger using an original Samsung USB-C cable.
- The device was inside a leather wallet case and placed close to where the owner and child were sleeping.
- Similar battery-related failures have been reported earlier this year with other Samsung devices, including Galaxy S25 Plus, Galaxy S24, and Galaxy Buds FE.
Details Behind the Overnight Explosion
The incident unfolded when the phone owner woke to loud popping noises, initially mistaken for fireworks. Upon investigation, it became clear the Galaxy S25 FE was experiencing thermal runaway—a dangerous battery failure causing the device to overheat and catch fire. The phone was charging next to the bed, inside a leather wallet case, plugged into a third-party 20W USB-PD charger via Samsung’s original USB-C cable.
The explosion caused minor burns to the owner’s neck and singed hair, with smoke spreading throughout the bedroom. Firefighters were called to the scene. Images shared online show the extent of the damage to the device and the surrounding area.
Charging Setup Sparks Debate
Online discussions quickly focused on the charging conditions. Some pointed to the leather wallet case and mattress as potential contributors, as both can restrict heat dissipation. While these factors can influence temperature buildup, modern smartphones are designed with sensors that monitor battery and internal temperatures during charging.
These sensors typically throttle charging speed or halt power intake if temperatures rise beyond safe thresholds, aiming to prevent exactly this kind of dangerous overheating. Users familiar with fast charging might have noticed their devices slow charging when warm, a safety feature that activates well before critical temperatures are reached.
Is This Part of a Larger Pattern?
This is not an isolated incident for Samsung’s recent flagship lineup. Earlier in 2026, reports emerged of similar battery failures with the Galaxy S25 Plus and Galaxy S24 models. Additionally, there was a widely reported case involving Galaxy Buds FE earbuds exploding during use, resulting in serious injury claims.
Samsung has a history of addressing battery safety rigorously, especially following the Galaxy Note 7 recalls in 2016. Since then, the company has reportedly implemented extensive battery testing and safety protocols to prevent such failures.
What’s Next for Users and Samsung?
Given that smartphones have multiple layers of protection against overheating and battery failures, the key question remains: what exactly went wrong in these cases? Only a thorough investigation can determine the root cause, whether it be a manufacturing defect, charger compatibility issue, or other factors.
Until more information becomes available, users should exercise caution with charging practices—avoiding charging devices under pillows or inside cases that trap heat—and stay tuned for official updates from Samsung regarding these incidents.
