"Changed charger port now no cell coverage"に関する回答I also have this problem after I changed the Lightning assembly as described on iFixit. The phone now charges great, but the Settings > Battery shows that "No Cell Coverage" is hogging 30-40% of the battery. The phone will run through its entire charge from 100% to auto power off in about 8 hours, just sitting on a table not being used. Often "No Service" appears in the top left of the display, or "Verizon" either with either 0, 1, 2 dots or no dot display at all in the meter. It also occasionally displays "Extended".

(Picture 4) Remove the screws that were hidden by the gliders. (Picture 5) Lift the upper shell away from the base. (Picture 6) Remove the two remaining screws that hold the blue top to the rest of the shell. (Picture 7) These screws are smaller than the four screws removed in prior steps. Keep them separate from the other four. (Picture 8) Push the 2 blue tabs toward the centerline of the mouse, using your...
