My 820 gets stuck on the shutdown screen with the big circular shutdown icon and then just runs the battery to dead. You can hold the button to try to force it to reset, but usually it just turns itself back on and sometimes will shutdown after that. Or you keep trying. Please fix your buggy software.
I have experienced this several times too. I got used to check if it is really off, but if I forget and and it hangs, batteries are flat for the next ride. Annoying. My wild guess is that is has something to do with a lost bluetooth connection.
Garmin, can we provide any useful information on that bug?
Went to go for a ride this morning and the battery was dead. I turned it off at 80% battery life. The screen was black and off before I put it away. Something running in the background with the screen off?
same than you guys, i had this issue on 8.00 and still with 8.40. Sometimes it gets stucks on the shut down screen with this circle never dissapearing, and sometime, presing shutdown does not do anything...Always need to hardshutdown the device. My battery is @ 100%... a bit annoying indeed
I confirm this annoying bug which I noticed the first time between June, 12-18th in 2017, while travelling through the Italian Alpes near the Passo dello Stelvio. From my point of view, there are three ways to shut down the Edge 820, each of them by means of the key on the upper left side. First, short pressing causes a suspend, i.e. a quick transition to a passive state, where the Edge quickly returns to the former active state. Second, longer pressing (a few seconds) brings up a menu with the four items 'Lock Screen', 'Power Options', 'Sleep' and 'Power Off', where the Edge needs more time to return to the active state than in the first case. Third, long pressing (at least 10 seconds) causes a 'hard shutdown', presumably comparable to holding the PCs power button when the operating systems freezes and the device needs several minutes to return to the active state.
None of these three approaches suffices to definitely power off my Edge 820. One day it refuses to stay powered off completely and immediately starts up again after shutdown. The other day it takes 10-15 minutes resting time before it switches back from passive to active state. Sometimes I see that the Edge has returned to active state and try shutdown several times before I give up because it restarts in the majority of cases. Sometimes I don't see and the next day the battery is dead. Since I am not a race biker, I don't care too much about weight. I have hub dynamo and just recharge the battery. But this bug makes the Edge 820 useless for serious race bikers since they never know wether there is battery power left or not.
I suspect that this bug is connected to data synchronization via WIFI. There are rumors in this forum, that the Edges WIFI client tries to upload the finished ride to Garmin Connect as long as the data is completely sychronized ... or as the battery is dead, whatever comes first. 'Rumors' because none of the Edges features seems to be documented or even specified (which, of cause, makes determined software development and testing impossible, but this is another Garmin story to be told another time). Instead, mere hints on these features just fall from the sky and therefore are no trustworthy groundwork. Since the built-in WIFI client is far from reliable -- this is yet another Garmin 'feature': the Edge often doesn't connect to networks already configured and obviously accessible (verified via smart phone or notebook, e.g.) -- the battery drains out before the data upload finishes.
This happenned again this week end!! prepare my ride on the saturday, charged the unit and powered it off... Did not checked that the unit was actually really off, so on sunday while preparing my stuff, the EDGE had no power..arghh..charge the best I could but the edge finally switch of 15 km before the end of the ride.. not a big deal, but really annoying, especially when you prepare everything..
The WIFI is turned off in the unit, I am not using it..
