Hello Jerome,
Welcome to the Bose Community and thank you for making your first post.
I am sorry to hear that you experiencing this battery issue with your SoundLink Revolve + Speaker.
My first recommendation would be to reset your speaker. You can do this by unplugging the speaker from power and turning it on using the battery power. Then press and hold the Multi-function (•○•) button for 10 seconds until the product lights glow, then release the button. Here is a guide if you need it: Resetting your SoundLink Revolve + Speaker
Another suggestion would be to check for and install any latest updates for the speaker. This can be done by visiting btu.bose.com on a computer/laptop and following the instructions presented.
Alternatively, you can update the speaker from the Bose Connect App. An update icon will be displayed over the image of your SoundLink Revolve + if an update is available.
Let me know how you get on with these steps, and if you require any further assistance, I will be happy to help.
Warm regards,
Charlotte G - Community Support
