Battery Level Insufficient (but not because it isn't charged)
I have had my xm4 headphones for a while now. At one point, the left swivel broke, and I was thinking about repairing them. So, I disassembled them. To do that, I had to start with the right ear to go in order of the steps. Along the way, I must've messed up the battery connection. The battery charges up all the way, and I get the same amount of time out of them on a charge-- but, my headphones THINK that they are ALWAYS at 10%. As annoying as it is to never know how much battery life I had left, it I was just a small nuisance.
Now, I need to update the software on my headphones. But, in order to do that, they have to be sufficiently charged. I can't update them over Bluetooth, because they will never believe that they're charged above 10% (even when fully charged).
Is there a way to download the update to my laptop and transfer the files my headphones with a cable? This has gone from minor inconvenience to a really aggravating issue now.
