I never had this issue at the rate your having. It did bring down the battery more but not 10% an hour.....something is defiantly not correct. I had a 500, then a 520, not a 1030. Only the 520 and my new 1030 were live connected to my phone. I will say however my newer iPhone does better than my old 6 year old version...…
Check with garmin, either call or do the live chat. They have good CS if you DONT do the email exchange…..
