Chosen Solution
Hello, I succesfully changed my iPhone 5s battery. Everything went ok, I just had a little trouble taking the battery out, but didn’t damage anything. I followed the guide backwards and went plugging everything in step by step. I closed the phone and everthing works just fine. The only thing that doesn’t work is the motion sensor. I have noticed that neither the compas or the Health app detect any motion. Plus, when I turn the phone, pictures don’t turn as well. I checked and turn is not blocked and I haven’t changed any motion related settings, I’m positive it’s a hardware problem. Thanks a lot in advance.
You can damage the motion chip that is located near the screen connecrors chances are you have damaged it
I just experienced the same symptoms: Replaced the battery, and afterwards none of the sensors worked. After searching more than just the “how to” videos, I found ifixit’s step-by-step online guide. I cannot emphasize enough: The four (4) screws securing the RFI shield over the cable connectors are 3 different lengths. The differences are too small to see with the unaided eye. But if you put them in the wrong holes, you can disable the sensors (best case), or damage the logic board (worst case!). Fortunately, I have a set of micrometers, and was able to measure the screw lengths precisely. After disassembling again, measuring each one, and reassembling with the right screws in the right holes, all sensor functions were restored to normal. Hallelujah!
