We have had many customers lately coming into the shop having issues with their iPhone charging. Symptoms include the following:
1. My charger will only charge my battery if it has power but not if its stone cold dead.
2. My phone shows that its charging but the percentage never increases.
3. Sometimes my phone charges and sometimes it doesn't
4. My phone doesn't charge at all.
5. My phone powers on and shows the Apple logo but then turns off.
If you are one of the persons experiencing this problem you may have a problem with a chip on your motherboard called "Tristar." This chip is responsible for allowing your phone to accept a charge and when its damaged it can cause symptoms that are not always the same for each person. The main problem is people are not using a MFI certified iPhone charging cable. The reason you want to use a MFI certified cable is that Apple is actually providing the tiny circuit boards and chips which protect your phone from power surges and only allows a certain amount of power to enter your device. Without the proper chips provided by Apple you are risking the life of your device. Just to give you an idea, Apple normally charges around $5-$6 for the MFI circuit board to cable manufacturers and chips that go in the tip of the charger. So 9 times out of 10 if your on Amazon or eBay and see a charger for $2 you are more than likely buying poison for your cellphone so BUYER BEWARE cheaper isn't always better. Attached is a photo of the cables we sell in the shop that are MIFI certified and this way you have an idea of what should be under the plastic end piece of the charger.
Looking for a MFI certified charger that you can trust to not damage your device. Below I have provided two products by "Anker" a well known Mfi cable seller. One is for the standard 3' cable and the other link is for the longer 10' cable. Both of these cables come with Anker's one year warranty also. I love these cables because they are safe, fast charging and Anker stands behind their product like no other company.
