Good news iPhone 5 users: Your smartphone probably won’t leave you with horrible chemical burns. iFixIt and HealthyStuff recently torn apart the smartphone and then analyzed its chemical contents. The company’s then compared the iPhone 5 to 35 other smartphone models.
Researchers found that most new smartphones are made with less hazardous chemical,s and the iPhone 5 is one of the least chemically inclined devices. In fact, the only ‘high concern’ devices were built before 2012.
The iPhone 5 scored a 2.8 on a five point scale, slightly worse than the iPhone 4 which received a 2.69.
The device’s score was based on chemicals, components, and a final overall build.
In comparison, the iPhone 2G managed a 5.0 ranking, the worst possible score for chemical and component builds.
If nothing else, the study shows that Apple is actively attempting to reduce its dependency on cheap chemicals that were once used en masse to build smartphones.
Chemicals found in the iPhone 5 include bromine, chlorine, lead, and mercury. Those chemicals were found in the devices casing, circuit board, processor, and buttons.
What might be most surprising is the study’s discovery that manufacturers tend to be widely inconsistent across their various smartphone models. For example, the Samsung Captivate scored a 2.71 while the Samsung Propel scored a 3.60.
Here is the full ranking chart for the 36 smartphones examined:
