In a week my ear buds have gone from around the 6-7 hours of playback i've been used to to lasting around an hour at best. Is this likely to be dying batteries? If so how easy are they to replace, and if not what could be causing this?

I had the same problem and yes, the batteries are (somewhat) easy to replace - both in the earpieces and in the case. The problem will be finding good quality replacement batteries. The MX3 batteries although a lower capacity will work fine in the MX4's. There are tear-downs available on YouTube.
Don't forget to do a full reset once that batteries are changed.

Hey ifixit - we all could really use your assistance on this break-down and battery replacement. Especially sourcing of good replacement batteries.

Some issues could be
to fix the software on the buds find the sony buds app and reset the software. if that does not work it is most likely the batteries.
I Hope this helps,

This is a common problem that is believed to be caused by bad firmware pushed out by Sony that kills the battery. They are offering replacements even for units that are out of warranty.

Unfortunately, I am out of luck because I bought mine overseas and they're refusing service, so I'll just change them myself. :D

A big thing nobody mentions is ear wax!
It gets absorbed in the foam eventually blocking a significant amount of noise and fidelity, so you turn it up, which drains the battery significantly faster.
Use a toothpick, pull out the foam a bit a couple of mm, squeeze till clean with a tissue.
Be careful not to pull it all the way out or tear it as Sony is shocking for replacements, so are all Bluetooth ear bud companies. Don't compact the foam down, this will also block sound.
Damaged tips also let out sound, you can replace these but super pricey.
Keeping them clean can preserve the life of the battery as well as prolonging the need to replace it.
A repairable ear bud should have cheap and easily replaceable batteries, tips and foam. When one exists I'll buy it.

That’s not resolve the problem.
I use since the beginning some Comfly with the same result.
@anonovi I think you were referring to Comply headphone tips with a foam in them to prevent debris?
These would be good for people that need to replace the foam I'd say.
You'd still need to clean the Comply tips and the wax could still penetrate down in the original foam reducing sound.
I've noticed many times a good cleaning can increase battery life by over 30%, however of course this is not the only cause for low battery life and some may not be affected.
However it's something worth looking into.
The XM4's battery life dipped after a month or 2 of use for me where as the XM3's lasted longer to begin with and didn't dip for 6 months to a year. I only get about 3+ hrs out of them if they're clean, less than 2 hrs if dirty. Still I've not properly tested these numbers so take them with a grain of salt.
I'll look into getting some Comply tips. Thanks for the tip :)

Is it under warranty for Sony service or repair? Check Sony's website for FAQs (battery life of container and ear buds, number of charging cycles, etc). Are electrical contacts free of debris?

I am having this issue as well, though mine starting dying just a year after purchase. Conveniently outside of warranty. Apparently this is a well known issue with these buds which Sony is doing nothing about. Doing some light research allowed me to find dozens of similar cases where just after warranty they essentially die.
Sony service essentially said I'm out of luck. I can pay to ship them in and have them repaired or buy a brand new pair.
If anyone knows where to get batteries and how to replace them in the earbuds and charging case that'd be fantastic. Other than the battery issue these are great buds and I'd like to not have to replace them.
