There’s a very simple reason why manufacturers recommend using only authorized accessories for their devices and it’s not the desire to increase their revenue or profit. Unauthorized accessories may easily damage the hardware or, in extreme circumstances, even pose danger to the user. A number of iPhone owners from the United Kingdom will certainly never forget that using cheaper non-oem third-party chargers is a bad idea.
Why you shouldn’t use non-original chargers
A repair company Mendmyi has recently noticed that the number of iPhone 5 handsets send in for repair has dramatically increased. Surprisingly, all devices seemed to suffer from exactly the same problem. For some reason the battery appeared completely dead – it wouldn’t take a charge or even light up the screen. Specialists from Mendmyi were totally baffled when they discovered that even with a brand new battery in the phone behaved the same way. It became obvious that it wasn’t the battery that was causing the problems.
In order to get to the bottom of the issue, the team took apart the iPhone 5 and carefully examined its components until they found the culprit – a damaged U2 IC. The name may sound like a music band, but the component’s role is crucial to functioning of the device since it “controls the charge to the battery, runs the power to the sleep/wake button, controls the USB function and regulates the charging to the power IC that charges the iPhone 5.” When the U2 IC is not working properly, the phone is unable to take a charge and power on which results in blank screen.
How could the U2 IC get damaged? Very simple – by using third-party chargers and USB leads. Smartphones, and other electronics for that matter, are very delicate devices and require properly regulated voltage and current. Even the slightest deviation can result in serious problems, like the ones iPhone 5 owners experienced.
It’s easy to get tempted to buy counterfeit accessories, since they are widely available and cheaper than those authorized by the manufacturer. In the long run, however, costs can be much higher as repairing the phone is definitely more expensive than buying official power adapters. Try to remember that next time when you look for a replacement charger.
