Like-for-like replacement in WF1000-XM4
I was tentative about buying new batteries for my failing WF1000-XM4 headphones, but these batteries appear to be the same brand and so far have been working as expected when swapped as per the ifixit guide.

One Good, One Bad
Replaced the batteries in both of my MX4s and discovered that the left one was still losing charge at an alarming rate (about an hour). Swapped the cells over between the two and the right one was losing charge at the same rate. The other cell was on course for an 8hour run time, but there was no way I was going to charge the other bud 8 times to test it. Send back for a refund and ordered cells from another seller. Time will tell.BTW, the cells that arrived were the correct Z55H Zenopower ones, so that's something...hence 3 stars and not 1.

from 20 minute battery to 8 hours
I replaced my WF-1000XM4 right earpiece's battery since it was only lasting about 25~ minutes on a full charge. These batteries have the exact same markings/labels as the original battery that was in my earphone, and after replacing the battery my right earpiece now matches the battery life of my left one (around 8 hours for a full charge)
