There is a very high chance that the fake iPhone charger you are using currently is highly unsafe. A study by British business watchdog Trading Standards, claims that 99% of counterfeit Apple chargers that are purchased online have one thing in common; they all have a very high probability of failing a very simple and basic test.
The researchers purchased around 400 Apple chargers from various retailers around the globe and put them through tests to see if they would pass the minimum required safety standards. Out of the 400 chargers, 397 of them failed.
Most fake chargers are known to be the cause behind phones overheating which is very disconcerting as these overheating issues are known to have caused house fires in the past. Apple filed a lawsuit against online retailers after it was discovered that 90% of iPhone chargers sold on online retail websites like Amazon are fake.
If you are one of those people who have bought an iPhone charging cable online, we suggest you dump it right now and get yourself an original charger. Not only does it cause overheating but recently we discovered it also messes with your battery life.
