Over the years the company Apple Lossless Audio CODEC (ALAC), warned owners of wired iDevices lightning to avoid counterfeit chargers because they are dangerous. Well, although we are not talking about an imminent danger to our physical integrity, these chargers can affect the face of U2 of the logic board, i.e. that chip that controls the charging of the battery of our terminals over time.
The cause of this component becoming faulty is really quite simple — third party chargers and USB leads! The original Apple chargers and USB leads regulate the voltage and current to a level that protects your valuable iPhone and prevents it from damage.
According to recognized service of iDevices in the UK, using chargers lightning Counterfeit can destroy that U2 chip, so a iPhone or a tablet iPad could it refuses to start after discharging the battery. more than that, the battery could refuses to charge beyond the 1% level after a full download, situation in which you will have to replace the logic board of the terminal.
Charging your iPhone using a third party charger or USB lead that does not regulate this as much allows for larger variables in voltage and current, this then damages the U2 IC and can leave you with a seemingly dead iPhone 5.
Although a complete battery change will make the terminal work, at the moment of its complete discharge the problem will return, so practically you do not have any simple solution for the problem. At the root of all the problems is the fact that counterfeit chargers do not correctly regulate the voltage sent to the terminal and battery, so that over time the U2 chip breaks down completely without distinction.
Although initially the company only talked about problems that affected iPhone 5, it seems neither iPhone 5C or iPhone 5S they are not exempt from them, although they have a different integrated U2 chip, in the case of iPad tablets the situation is similar. Considering that Apple has been around for more than a year opened a program by which it replaces counterfeit chargers with some originals for a modest price, I recommend you take advantage of it.
