iPhone battery drain w/ Garmin connect

I have looked through the forums and have seen some talk about this, but I haven't had issues with battery drain until the last 2 months. I just realised the culprit with battery drain on my iPhone (s) is Garmin Connect.

I have a iPhone SE since new, and I was putting the recent battery drain on the phone down to the fact the phone is 3 years old. It got so bad I switched to a new (old stock) iPhone 5c I keep as a back up. Same thing.

I'm now on holiday on a bike trip and stupidly forgot both my edge 1000 AND the charging cable for my 735xt. So I'm stuck using the Strava iPhone app. I turned off Bluetooth on my 735xt and closed the garmin app and wouldn't you know my battery life on my iPhone 5c is back to as it should be. Very little drain while on a 3 hour ride with the Strava app open and recording (also had BT HR and cadence sensors paired as well as periodically looking at the map).

I've used garmin watches for years (original vivoactive, fenix 1,2,3, and now 735xt) and don't remember battery drain being this much of a problem with Garmin connect?

iPhone 5c iOS version 10.0.2
Garmin Connect Mobile version 4.4.0.19

    Same problem here. iPhone 8 with 91% battery life. The phone is drained during the night. When examining battery usage, there are several 100% peak usages around 2 - 4 am. Garmin Connect is using 40-60% of my battery.

    Change the location services to “while using” and will be much better

    It won't help a great deal - the problem is with the appalling software. I've been using Connect on my (work) Android phone, which is pretty much okay, because the iOS version is so awful.

    Because there have been a couple of updates to the iOS version since I last tried it, I thought I'd give it a go today. It took multiple attempts to persuade the Edge 1000 to pair at all, and then when it did the ensuing Livetrack failed sixty miles into the ride (to be fair, this represents slightly better than typical perfornce, compared to the last version I'd used on my iPhone). On getting home (after 4.5 hours), however, the phone - which had been more-or-less fully charged before the ride - was down to 15% battery, despite not having been used for anything else. Connect had used 76% of it - the next highest was Mail, at 4%. Obviously, discharging the phone almost completely in a morning effectively means the app is unusable, and your suggestion would clearly not have helped in this instance, because Locastion Services would be required for the app to function during the ride.
