- Yellow flashes - stuck at 90%
I am on my 5th Revolve with this 'problem' and the last three were sent to me from Bose brand new - the latest in December.
I don't mind not using my Revolve and that over time they go below 100% as long as they charge back to 100%. And I only use 2 amp connectors/ports for charging (the Revolve needs 1.55 amps to charge)
Yesterday I went to charge the newest Revolve which reported 90%. I let it charge over night and this afternoon, I noticed it was still blinking yellow and still reported 90%. I went through my 'procedure' below and charged for an hour and still blinked at 90%. I repeated the procedure a second time and it turned green in under 5 minutes and reported 100%.
I still can't be sure totally what th e 'problem' is that is preventing it from getting back to 100% but I do not believe it is battery or charging related or exclusively related to them. As the procedure involves a complete factory re-initialization, it seems to me that I am resetting something that is preventing the firmware from properly charging to 100%. Many people have checked in about Revolve charging not going back to 100%. I have reported this to Bose many times over the last two years and responded to dozens (literally) of posts on this topic here. It would sure be nice if Bose would look at some of these units to diagnose the problem and fix the firmware - again there is nothing wrong with the batteries - it has happened to me now 8 times across 5 units and on 3 of them, the Revolves were under 90 days old.
What I do (sometimes more than once)(this is a modification of Bose's procedure):
1. Start by unplugging the unit
2. Turn off by holding down the multifunction key
3. Turn on (may need to hit the on top button twice)
4. Turn off by holding down the top button at least 10 seconds. This reinitializes the unit.
6. If turns green, turn on and answer the English prompt
7. If not green, repeat the procedure and charge after the English prompt.
8. Most of the time 1 or 2 repeats should get it to turn green.
9. Occasionally, for steps that turn off the unit, you may need to plug it in to get the unit on.
