Probably familiar story, 2 years 8 months old, battery ride time has deteriorated rapidly over last 6 months, now down to about 4 hours ( 57% left after 1 hour 45 mins,) no Connect IQ apps, basic settings, minimal backlight and manual/30% brightness.No navigation or powermeter. All garmin support can offer is to add me to the open case on the known issue and £120 for a replacement. It charges fine and retains 100% overnight so not draining when powered off. I have done full factory reset etc.
By comparison, new Garmin 830 , 9% battery usage after 3 hours. I haven't needed to charge it for 10 days/ 15 hours use and still 40% left. My 800 and 500 are still going and better than my 820, I am a real glutton for punishment , also using Vector 3, , just received the second batch of new battery doors along with the screw in base this time.
Any 820 thoughts or advice?
I have made my " I should be considered a valued/loyal customer and I deserve better " points to garmin support.
thanks
Mike
