Shimano D-Fly Affecting Battery Life
Moderator: robbosmans
Has anyone noticed that the D-Fly affects the life of your internal battery and that of your Garmin? I did a 2 hour ride last night and my Garmin was down to 85%, when it would normally be in the low-90s. My internal battery was down to 90%, when I would expect it to be 95% (based on when I last charged it). I would expect an additional transmission device to use more juice. Just wondering what others have experienced. Thanks!

Had the same problem, specially on Di2.
This is definitely a first world problem. I still get over a month of riding before I feel the need to charge my di2 battery, and it still is at 25%..........
The garmin battery drain on my edge 1000 is about 10% per hour, so still plenty of time....

It affects the Garmin a lot more than Di2. Been over 3 months since I last charged the Di2 battery.
Garmin power drain is still mostly the screen though. Man I wish Garmin would adopt OLED technology. Black pixels not requiring power is a huge win. I'd guess improvements of at least 3 additional hours on the Edge 1000. The current LCDs drain power hard.

When the D-Fly unit was install was all the firmware updated? If not, mismatching firmware can fail to shut off certain components causing parasitic draw. Make sure the newest version of the E-tube software is installed on the computer doing the update.

Maybe that explains why I have not noticed any changes in battery life with my garmin 510 or Di2.

I have updated software for both my Garmin 510 and Shimano Di2, and have noticed a significant difference in battery life since installing the D-Fly earlier this year.
I haven't done a rigorous test. Anecdotally, last year I would charge the Di2 (internal battery) every 2-3 months. On a recent trip to Mallorca and Puglia, I noticed that I would lose up to 10% of the Di2 each day. That surprised me and I was glad that I brought the Di2 charger along with me. Lately I've noticed battery drain on the Di2 to be a bit less than that, say 5% per day. I wonder what kind of activity draws more battery than others.
I haven't noticed much change on the Garmin, and it's much less of a hassle to recharge the Garmin.

before i installed the d-fly my di2 battery would last about 3 times as long. I got a shock while out on a ride shortly after the install. i had 30%, this dropped shortly to 20 or 25% but over the next 4 hours it dropped to 5% and i lost the use of my front derailleur. Guess i was lucky i was at the top of a climb on Gran Canaria so it was pretty much down hill all the way home. Admittedly i had been constantly playing with the hidden buttons under the hoods on my DA shifters to change screes. It was a new toy so i couldn't resist. I figure i charge the di2 roughly every 40-50hours of ride time now..i think.
I have 6 month old bike with DI2 and a Garmin Edge 1000, and I use the D-Fly transmitter to connect them.
When I park the bike for a few days, I notice that the DI2 battery level goes down, on one occasion it drained completely. On the other hand, riding the bike doesn't show any unexpected battery drain.
I normally keep the Garmin close to the bike, and I haven't been in the habit of powering down the GPS by pressing and holding the side button.
Last week I thought that this might be causing the battery drain, so I powered the unit down. The bike has been parked for a week and a half now, and the battery still shows 100%.
Hopefully I have found the answer to this problem.
