Preserving battery

[tomsag]

Hi to all owners of these nice IEMs.

got them yesterday, and found that they seem not to be able to be left alone by not charged to 100% in the box? If out of the box they seem to be in use and will drain to 0% SOC.


If I leave them for a longer time period at full charge, the battery will suffer long term. Anyone put the strip on the metal charging connectors (as it was when purchased)?

If anyone wonders why I'm in it - have an EV car and it makes sense to care about the battery.

Quick update:

Been NOT using them for 3 days, they were in the charging case (about 60% power left in the box), and now - everything is totally DEAD. 0%??

Hope anyone has them to either confirm that this is expected (?) or are mine faulty?
