It’s because you put the case down unevenly and most of the charge sloshed to one side
Fixed

Happens to me all the time! Infuriating!
Likely dirty/corroded charger connecting points that make the charging contact intermittent.
Clean them, scrape off the layer of crust/corrosion with a jewler’s screwdriver if you have to. Once they’re clean and charge well again, I recommend putting a little dab of dielectric grease to protect them from corroding again.
Mine started doing that a year after I bought them and I was about to throw them away when I tried doing that and it completely fixed it.
Most of the comments here completely miss the fact that difference in the OP appears after charging, not after using. It doesn’t matter if one is primary or not, they both had the same amount of time to charge from 0%, so they should be the same.
This is if they have the same size battery, which might not be the case if one needs more to work.
Also, the state of charge might be inaccurate, it might report zero on a secondary one if the primary is also down just so you put it both back on charger so they equalise.
Also it might all be bullshit and we’re speculating on it randomly.Also it might all be bullshit and we’re speculating on it randomly.

Could it be that only one of them connects to the phone, and then connects to the other earbud also, thus using up more power?
Huh. This happens to me in a different way with OpenRun headphones. They don’t auto shutdown when disconnected. You have to turn them off because they just stay on until the next time you want to use them.
And then you pick them up a few days later thinking they should be fine, but no, they spent days idling and only have a few minutes of use left.
it’s always the left ear, why? i want to know too.
It’s the primary device, so audio and microphone and such by default go through there. It’s been listening for the hey Siri for about 12 hours when the right ear hasn’t had too
Likely the “brain” for the pair is on that side and the extra load of doing it’s job has worn down the battery’s life faster on that side.
reasing this while my case is so empty that my headphones dont even turn on when i take them out, even though they still have charge (i used them just 20 minutes ago)
This is actually the primary reason I switched from Pixel to iPhone. I was sick and fed up of leaving the house, opening up the pixel buds case and 1 bud not connecting, or having minimal charge, or it just cuts out after a minute of listening to something. Standing in the middle of the street troubleshooting earbuds whilst I just want to listen to something whilst going somewhere was so frustrating. Moved to iphone and airpods - not had an issues since (about 2 years now). Yes I tried different earbuds with my pixel. No, they weren’t any better. In-fact I still have some and they work better with my iphone.
I don’t go in for fanboism when it comes to tech companies, but the build quality of Samsung and Google is atrocious.
yeah but I’ll take it over a wired set where one has to have the cord wrapped around my ear in a specific way for sound to come out.
except no because a good enough replacement set was like 20 bucks and high end ones have always had and still do have removable cables.
You don’t even need higher end ear buds for replaceable cables anymore. Moondrop CHU 2 are 20-25 € and come with a replaceable cable. The DSP version comes with a nice usb-c cable.
Just make sure to get them from an official retailer; Chinese stuff like this often sells returns on Amazon, non-specialized retailers, etc. Hifi retailers like linsoul, Hifigo, Shenzhen audio, are the only ones where you’ll reliably get a working product. Otherwise the quality is quite good.
Clean the case you nasty ass
Which pocket do you keep your phone in?
