Chosen Solution

Hi I’m having a problem with my iPhone 6, I was trying to put a iPhone 6s battery not knowing it wouldn’t fit, but then I realized it and put an iPhone 6 battery but when I powered it on, the Apple logo turn on for about 3 seconds and then turns off and the lcd just lights blue and it stays like that…… Anyone can help I would appreciate it. Thanks guys….. Yelesay,

Hi Most probably you damaged battery connector on motherboard. iPhone 6 battery has 4 connections but 6s has 3 connections. I think when u try to connect 6s battery one of connecting pin in motherboard is bent inside or get damaged. Inspect carefully for damage under microscope and check with multimeter for battery connections pins on motherboard. If this is problem then possible solutions are

  1. If any pin is bent inside with sharp tweezer make it in original position.
  2. Replace motherboard connector if you comfortable with it.
  3. Make small jumper from battery to damaged battery connector. I hope this will be helpful to you. Thanks Micky
