Sony WF 1000XM4 Left Earbud draining 10 times faster than right

[Thommy]

Like the title states, my left earbud randomly started draining extremely fast.

I suspect the 2.0.1 firmware.

I bought these in Denmark on February 17 last year and now they are essentially worthless as I can only use the left earbud for about 40 minutes.

 

I have since moved countries to Japan, so I don't know what to do about warranty now 😞

I have a attached pictures showing the battery drain using both over about 1 hour.

Sony please respond.

I've recently got this problem with the rhs (100% flush in under an hour) after I changed the firmware update on (had auto update off) and got 2.0.1 .

Found this in way to many other threads......

I did all the known resets etc and pretty much rubbish.

I've had these for a while as a present, so no date of purchase or receipt, so got in touch with an unhelpful lady on the Sony helpline via chat after raising a Case.

Moved on to management after reminding her that this is a known problem.

Supposed to get a call back in 24hrs ?

I've recently had to return 2 of their TV's for other issues and pi%%ed off with them already.......
