Ok thanks for the help!
Yes, the problem just happened few weeks ago, it was all good before then one day I unplugged the wave, it was at 100% (left charging all night long) and after 3-4 hours it dropped instantly to 0% and since then its like that almost every day.
I don't know if it can help but this happened almost at the same time than the code 218 that randomly appears from time to time when I power on the wave. I have to either mess with the hands (move back and forth) or simply power off and power on again to make the code 2018 go away. Do you think this could be all linked to the battery drop issue?
