iPhone 5 ‘Not Charging’ Solution IC
This repair part and solution is for iPhone 5 that is not charging when connected to your computer or usb charger or battery not retaining charge when fully charged
You have changed the battery, dock connector, and checked that the FPC battery connector is OK, but it makes no difference in fixing your issue.
This is caused by an IC controller chip that is burnt out when it is damaged in any way it opens the circuit between the USB charger and the battery.
Some symptoms of an iPhone that has a faulty U2 IC are:
– Battery won’t charge beyond 1%
– iPhone automatically powers itself on
– when the battery is removed and the iPhone is placed on charge it does not boot to the Apple logo
– when the iPhone is put onto charge the screen stays blank and the iPhone remains lifeless
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.
Charging your iPhone using a third party charger or USB lead that does not regulate this as much as it allows for larger variables in voltage and current, this then damages the U2 IC and can leave you with a seemingly dead iPhone 5.
Another common reason for this is also charging your iPhone 5 from the cigarette lighter of your car. This does not regulate the voltage as well as the original AC adapter as the power is coming from the alternator.
It has been proven that non OEM / non original chargers cause this issue.
