Anker SoundCore Sports XL Battery draining in while its switch off

Hi,

I have bought Anker SoundCore Sports XL 2 months back from Amazon.
So I have fully charged my speaker and switched it off.
After few days(1-2 week) when I switched it on I found there was no battery remain in the speaker and I have to again fully charge it.

Any idea how can I troubleshoot the issue?

I did a similar situation post. Not sure if it’s a model year thing or what

Sounds like a battery defect in yours. Mine works fine. I’ve left mine off for a few weeks and it turned on just fine.
