What to Do If a Cell Phone Battery Catches Fire
Recognize lithium-ion battery failure, evacuate safely, call emergency services, avoid dangerous handling, and store damaged phones for professional disposal.
Quick Answer
Hissing, popping, smoke, a sweet or chemical odor, rapid heating, swelling, or flames can indicate lithium-ion battery failure. A battery fire can release toxic smoke and reignite after appearing to stop.
- Move people away and call emergency services if there is smoke, fire, or immediate danger.
- Do not hold, crush, puncture, or carry a burning or venting phone.
- If safe, disconnect power without approaching the battery.
- Close doors to contain smoke and evacuate according to local fire guidance.
