A 14-year-old girl from Kennebunk, Maine suffered second-degree burns when her iPhone 5c caught fire in her pants pocket. Fortunately, she was calm enough to remember to stop, drop, and roll, which considerably reduced her injuries. Lithium-ion batteries like those in the iPhone occasionally cause fires, but they are extremely rare and usually occur only while the phone is charging — there’s no reason to assume that this was anything more than a freak incident. follow link

decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.
