How's your battery life with 9.0 firmware?

I did a ride today, 31 miles the ride was exactly 2 hr 20 min. I was using navigation for part of it and a little live tracking (to test it out). At the end of the ride my battery was down to 11% remaining. I turned navigation and live tracking off for the back 1/2 cause I noticed the battery getting drained so quick. I never got 15 hours either, but I was able to squeek out 10-11 hours with navigation in the past (or at least partial navigation).

Your not alone.

Not been happy with the 820 since I got it. This is just another cherry on top.

Not yet but sure has to see with Bluetooth connectivity that change with this fw 9.00.

This fw 9.00 brings all things of problems to the users of Edge 820, with the connections with the phone. Maybe also consume more energy for loosing the connection with the phone and the reconnection with it, like happens to me.

Hope help you,
Regards!

I struggled greatly with pairing my 820 to my iPhone after the update. I spent over 2 hours going through every possible combination of actions before I was finally able to sync a ride I had already completed with the new firmware. I can't believe this is the way it is ...

Anyways, I had already noted poor battery performance last weekend with the 9.0 firmware while navigating, so I chose to go oldschool and bring a printed cue sheet for today's 100+ mile route. Connected sensors included my Garmin HRM, GSC-10, and Pioneer power meter. The 820 was paired to my phone, but no live tracking, no live Strava segments, etc.

What I did notice is that battery drain on my iPhone has improved! Normally I'd see it drained down to 50% after a 6 hour ride, but today I still had 80% left. But I'd gladly trade that back for the improved Garmin battery performance I used to have prior to the 9.0 firmware!

Probably from what I understand in your comments is that perhaps during the ride the device was not paired with the iPhone.

Maybe that's why the iPhone did not have so much battery consumption, but the Garmin was perhaps spending battery unnecessarily trying to pair with the iPhone.

I can not think of anything else. I have not been able to ride since I am sick and just today I am beginning to improve. So when I can do a ride of several hours I will notice if there is less battery charge after the 9.00 fw.

I still did not want to do the downgrade to 8.70 waiting for Garmin to quickly provide some Fix ... But the best solution at the moment is to do the downgrade. Firmware 9.00 brings so many problems to users, that it is better to return to the previous version.

Its not good, i started at 100% battery after like an hour ride it dropped to 75% (connected sensors are HRM, Di2 and cadence) which is unusual and it goes down noticeably, my battery life was good (everything works well) prior to this 9.0 update, after the update a lot has been affected not just battery life but also bluetooth connections and the auto upload too.

Whats up GARMIN??? whats the agenda here???

If you're having issues after a software update the first thing to try is a reset of your device

Did a factory reset just like what the manual says but still, Bluetooth connection is an issue battery life and all.. my edge 820 was really working fine without an issue before i updated it to to the current 9.0.

For me, battery life has been far worse than the specs even before 9.00, and even with Bluetooth turned off.

Confirming that something went wrong with FW 9.0 (have bluetooth phone connected, and an array of sensors - Di2, Light, Vector, Speed Sensor, HRM).

Settings that seem to affect battery like (apart from cold, which is kind of obvious): navigation (effectively halves battery life) and screen backlight (auto mode works fine, but seems to drain battery 1.5x faster compared to backlight off).

After all, I'm getting no more than 6 hrs with navigation and backlight (when its <10C degrees, goes down to 5 hrs).
