I have recently had some problems charging my iPhone 7 from my 2013 Macbook Air. For a while, the phone would only charge if I had the lightning cable turned a certain way, otherwise it would do that incredibly annoying connecting/disconnecting thing. It now refuses to charge at all when connected to the laptop. The strange thing is - my laptop charges my portable phone charger fine [suggesting the laptop port isn't the issue] and the phone charger works with my iPhone fine [suggesting the phone isn't the issue either]. And I have tested 2 different cables [one new, one is an apple with no signs of wear and tear] and both work with other devices.
I have, previously [March last year] had some issues with the headphone port requiring the following repair. I am wondering if the two could be correlated, if there is any "easy" fix or if I should just take it into Apple.
The problem description/diagnosis from last time:
Issue: Machine fans get loud and no sound from machine
Steps to Reproduce: observed the issue, Performed visual mechanical inspection, ran Mac Resource Inspector and noted machine had a thermal sensor warning
Proposed Resolution: Replace I/O flex and test. If unsuccessful replace I/O board. Run ASD/EFI & OS as post repair testing and ensure there is sound in users operating issues
