Bose Soundsport Free not fully charging
I bought a pair of Bose Soundsport Free headphones back in summer of 2018, and while they have worked great so far, now I'm having the issue of them not accepting full charge when docked in their case. The case is at full charge, full 5 bars, yet after charging the headphones will only have accepted enough power to get them through around 45 minutes of playtime before the left one dies, and before long, the right one dies as well.
My Bose Connect app claims that the software for the headphones is currently all up to date.
I wondered if the metal charging points on the headphones was dirty, and cleaned them with a cotton swab and rubbing alcohol, but the problem still persists.
I've seen a couple other people reporting this issue, but they speak of malfunctioning cases and whatnot. Is there any solution to possibly fix this?
