I have a weird issue with my new HR in that the battery level in the app and on the watch are totally different. I charged it the day I had it, and ran the battery down almost fully then re-charged it. On the watch itself, it shows the correct reading (at the moment, its 100%, but whatever - the watch shows whatever the actual charge level is) but on the app, its giving me a warning that the watch is low on battery, stating its down at 3% and in power save mode. It isn't, its online and showing me all the usual display data.
I have tried re-pairing, rebooting everything and it doesn't seem to be making any difference at all. What I have noticed is if I kill the app and re-open it, the battery level shows correctly for about 2-3 seconds, then reverts back to 3% again! Its a simple thing, the functionality of the watch isn't really affected but I cant stop being slightly annoyed by it!
Anyone else had a similar issue, and found a work-around/fix. etc?
