Two similar incidents are alert to Apple.
On Wednesday, a battery from an iPhone in service in an Apple Store exploded, causing a fire.
The entire room was filled with smoke, but fortunately the employees quickly quenched the fire and no one was injured.
The incident occurred in an Apple Store in Valencia, Spain.
This is the second case of this kind in just days. Tuesday, a similar fire broke out at an Apple Store in Zurich, Switzerland, writes Phone Arena.
The employee who repairs the battery in the iPhone suffered minor burns when the battery gets fire. Seven other people were slightly injured.
In recent days, many Apple stores have more work as usual with changing batteries. That's after Apple offered the possibility of replacing old batteries with new ones for only $ 29.
The decision was made following the scandal that revealed that Apple slows the performance of older iPhone models so their battery does not fail.
Many users wanted to take advantage of the offer and change their battery.
