Di2 - different lights since firmware upgrade

Hi, I've got Di2 6870, and a couple of months ago on a ride the battery died, even though the charge indicator said 75% when I put it in the car.
As this was unusual, I did a firmware update with e-tube, and haven't ridden the bike since as winter has come. However the battery did go back to 75% again even though I wasn't using the bike. I looked for more firmware updates, and there was a new one for the main junction box SM-EW90 which I applied.
Now, the main point of what I'm asking is that now when I do a battery check, the unit displays the battery charge at 100%, solid green. BUT, then it flashes the charge indicator green, and the +/- light red at the same time, for around a second and then shuts off.
Does anyone know what this means? Is it a new feature of the latest firmware (Nov 2016 I think) or is it a new error or something? I can't seem to find anything for this behaviour elsewhere on the internet, so I'm hoping some DI2 experts on here might be able to help! I'm fairly technical so taking things apart and electronics don't worry me.
Local LBS's do not have DI2 diagnosics.
Thanks

Hopefully someone else will read this, maybe someone from Shimano or Madison!
Firmware changeling doesn't seem to have any mention of it either.

Excellent news. I just wish things like this were explicitly stated on the relevant Shimano pages rather than rely on knowledgeable people to deduce and pass the info on.
Many thanks.

Yeah, Shimano is making a pig's ear of the whole launch of the new 9150 Di2. Some bits available, some aren't. Updates that change your system for functionality that you don't have, etc. etc.
And the new Junction A control box in the handlebar end should be interesting as very few bars have the requisite holes drilled in them.....
And very few LBS's have the time or the inclination to get up to date with all this, so you're pretty much on your own really.
Here is the definitive answer:
Thanks for contacting us.
You probably have updated your junction A (SM-EW90 or similar) to the newest firmware. This firmware is ready to function with synchronized shifting. This is a new feature of our new Duta-Ace R9150 groupset.
For more information please check www.duraace.com
With synchronized shifting you can change between modes and the junction will show, by LED lights, which mode is selected. When both LED's are burning this means you are in manual mode and you have to change front and rear derailleur manually.
In the setup you are using only manual shifting is possible but it will still show this by illuminating both LED lights for 2 seconds.
Kind regards,
Got it delivered from the shop two days ago and having exactly the same "problem". I joined the forum precisely to ask this question!
I called the shop and they had no idea why this was happening. Good to hear that it is because of the upgrade...
In this video, you can see how it works;

Which site did you get the Junction box from? They're still pretty hard to find....?

I had the same thing, battery going flat very quickly, though it would last for a days riding. Swapped for a new battery under Shimano warranty and problem has gone away
LBS diagnosed it as a battery fault, and replaced it under warranty with Shimano / Madison.
Light was firmware, I just hoped the firmware would fix the drain issue, but it was simply a faulty battery. New one is even better, I've done over 300 miles and it's still saying 100% which is amazing!
I ve got in touch with Shimano service centre here in UK and this is the reply i got from them.

I believe thats a feature related to the synchro shift feature on the newer Di2 range, it flashes to indicate which shift mode it’s in. I assume yours is sharing the same firmware despite not having this feature.

Hi All at the bike service,
Hope you can help.
I updated my 6870 firmware to the latest available at the weekend and when I do a battery check, the unit displays the battery charge at 100%, solid green. BUT, then it flashes the charge indicator green, and the +/- light red at the same time, for around a second and then shuts off.
Is there a problem or glitch in the firmware ?
I had a 8 mile ride today but had no problem shifting the gears.
Jasbir.
So the battery level is always indicated by the green light behavior. My battery is giving about 2000Km, with mixed front/rear shifting activity.
Reason is I’m worried is my front mech stopped working out on a ride but had a full battery. It’s now working after a push of the wires.
Can’t be my battery as the green light stayed solid.
I’m going to invest in the Bluetooth connector so it tells me my battery level.
