Sony WH-H900N h.ear headphones stop charging after 1 minute
I have a pair of Sony WH-H900N h.ear headphones that are around 3.5 years old.
Lately the charging function has started to play up. They’ll be plugged in to charge, but won’t charge to 100%.
I assumed it was the battery, so following some instructions on IFIXIT, I ordered a replacement battery and replaced it.
Unfortunately, it seems the battery itself is fine, as the issue persists.
The charging light comes on when the headphones are plugged in to charge, but then only stays on for around one minute and then it stops charging. This is intermittent, as if I keep trying, it occasionally charges for longer and might get as high as 70% charged.
I’ve experimented with various charging cables and it’s definitely not a cable issue.
The most success I’ve had is when I put it on a very short cable so that the headphones are sort of hanging a little bit with some of the weight pulling slightly on the cable/port. It could just be coincidence that it’s worked mostly when they’re positioned like this.
I’m assuming it’s either the charge controller or the port that’s the issue.
Has anyone had experience with this who could point me in the right direction to try to fix them? They’re ridiculously expensive headphones, still in really good condition, and I’d really like them to last longer.

I just started having this exact same issue with my WH-H900N a couple of weeks ago.
I thought it was odd when I charged them overnight and didn’t have a green charge light, and got “Battery Level – medium” when I did a power check.
Today I tested it with a different cable and two different power adapters AND a battery pack. All with the same result: they stop charging after about 1 minute.
They’re stuck at about 70% charge, so I’m not sure how much longer they’ll last. There are no firmware updates currently available.

I think I found the problem with mine. If I fold the headphone it will stop charging after 1 minute. If I charge it will unfolded it looks like it keeps going
