No Power On Your Phone?

Why is my phone not turning on?! Do you ask this question to yourself? That is because it doesn’t have any power.

The times that I can count when a customer comes into A One Mobiles and Repairs saying why is my iPhone not turning on and i was just using it and it turned off.

This one can be easy! most commonly your phone has just got too tired and wants to go to sleep yes your phone wont turn on but why?, the memory could be full and and the nand chip is just overloaded and can’t take anymore of that scrolling. Here’s all you need to do, hold the home and lock button down for about 20 seconds until you see the apple logo again and then release the buttons and simply wait till it is fully awake again.

why no power

Another common issue that can cause your phone not to power up is a short on one or more of your rails on your motherboard. We in our industry will commonly hear our techs saying do you have a short on VCC_Main which is one of the line’s on an iPhone with no power. Well how do we diagnose that? there is a couple of ways to do that like external power supply and multi meters and when we do find it we can then remove the short that your phone has to allow power to smoothly flow through your circuitry.

Shorts on the board could be a capacitor or even your main power ic.
