3 Black screen, won't start after big crash
Dear all,
My Iphone 11 have a big crash and damaged the rear glass. Since this crash the phone don’t start black screen (I try to put in DFU - No result). If i connect my phone to the charger no heating it look like no powered.
Questions :
Do you know if an iphone can be start without battery, only with the charger ?
How can i test my battery ? I have Iphone X battery in spare part do you think it is the same connector ?
Thanks in advance, Best regards.
The batteries in the 11 and X are not compatible. If you wanted to test the battery, take a voltage measurement between the positive and negative pins. However, given that it stopped working after a fall, it is most likely a logic board issue.
