Hello guys, I have a problem with my iphone 6 plus. On headphone mode, the sound lost if I set volume below 80%. And the sound hurts my ear on >80% volume. It feels different with my 5s which has nice sound even on 100% volume. I use same original apple earpods. Before, my friend replaced the audio codec chip twice. First,when it stuck on headphone mode. Secondly, when my problem above appears. It only last few weeks. I already changed the dock connector,but no effects. Wish someone here can help me fix this problem. Sorry for bad english because it’s not my primary language. Thank you
It sounds like the Audio/Amp circuit is problematic. You say that your friend had to change the Audio Codec twice; was it twice during the same repair or on two separate occasions? Perhaps that’s not really your root cause here. It’s hard to troubleshoot this remotely with so little information. I would suggest you have an experienced micro-solderer take a look at your phone.
