Conflicting info Di2 Battery Light / Levels. Please clarify

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I've been using Di2 for ten years. Here's how my experience tells me to take them . . .

Solid green - 75%+
Flashing green - 50% to 75%
Solid red - 15% to 50%
Flashing red - Less than that.

As a practical matter, I recharge when the green starts flashing. Even though I put about 8,000 miles per year on the bike, I still only have to charge the battery three or four times a year. Charging on flashing green means I never have to worry about it.
I have to charge my Di2 about every 300 miles. How often do you change back and forth from big ring and small ring?

Whoa! Do you have the d-fly staying connected to Bluetooth when not in use by any chance? I’ve 150 miles after the last charge and it dropped to 90% from full charge.

300? That's way too often - I would have that checked. (Stores with the sm-pce02 can check for battery consumption issues).

You should be able to ride at least 1000 miles before having to charge, typically.

Either you shift your FD as often as I shift my RD...or you have a ground fault somewhere in Di2, or you have a battery going bad.

1500km or so is ballpark for normal usage.

300 miles? Wow. Something isn't right. I'm getting close to 3,000k per charge on my Di2.
