iPhones, iPods and iPads have been using Lightning Connectors since 2012 and it is a unique connector created by Apple. Inside each lightning connector is a tiny authentication chip (MFI or E75 Chip) that tells your device it’s Apple MFI Certified. This is important because non-certified or “knock-off” lightning cables can be very dangerous to your device as they don’t have this MFI chip. (You may have noticed a warning message on your phone when a non-MFI cable was detected.) These cables can often get extremely hot, cause damage to your phone and even render it completely fried and useless.
The following is the way we explain it to our customers:
“The certified cables have an MFI Chip that acts like a surge protector in an extension lead, protecting the charging circuit and battery of your iPhone from damage; thus prolonging the life of the device and battery.”
As a repair shop we see all sorts of damage to smart phones. You name it, we’ve seen it… from iPhone’s run over by lawnmowers to Samsung Galaxy’s dropped into the sea to smashed screens!
After broken screens, the most common repairs we have with iPhone’s are battery/power related. Here are a few examples:
The first are clogged charging ports. This is caused by a build up of pocket fluff, dust and dirt. It get’s compacted inside of the charging port every time the device gets plugged in. This usually happen with people who put their phone in their front jeans pocket with the charge port facing up. Over the course of time bits of fluff, etc… fall into the charge port. To prevent this from happening, put the phone in your pocket with the charge port down.
The second is poor battery performance, which you hear a lot of iPhone users complaining about. We use a program called 3uTools to assess the battery performance. This will tell us, among other things, the actual percentage of the battery, amount of charge cycles and boot values. We can use this information to advise our customer if their battery needs replacing.
The third is internal damage to the charging circuit of the iPhone. When Apple first brought out the Lightning Cable it didn’t take long for the market to be flooded with cheap copy cables. Sure what did it matter? A cable is a cable, right?
We strongly advise using an MFI Certified lightning cable. As pointed out above, these will prevent damage to the internal motherboard of your iPhone. We regularly see iPhones that aren’t that old but are suffering with rapid battery drain and also giving false percentages. The MFI chip is designed to protect the tri-star chip, PMIC (Power Management Integrated Chip) and battery from spikes and surges that may occur otherwise.
So hopefully now you can see the importance of using MFI Certified lightning Cables when charging your Apple device. It’ll prolong the battery and save you money in the long run. If you have cables that you’re unsure of, pop in to one of our stores and we can test them to see if they have the original MFI Chip inside!
