  • I fired up a new 5S+ yesterday. Saw some strange behaviour with the battery charging state as I was setting it up, updating software etc. Went from 58% to 100% very quickly, then back down to 60% after a short while. Back on the charger and took some time to get to 100%. Left it for a couple of hours. Went to bed around 10pm with it fully charged on my wrist. Now 17hrs later and down to 54% after about 2hrs of GPS activity in addition to using it as a watch. Used OHR for the walks, nothing else out of the normal. Used as it out of the box.I am using the simple digital watch face showing battery %age and date. I did notice after this mornings parkrun (walk) the battery initially showed 67%, but then a short while later was at 68%. Thought nothing of it, but just noticed now that it's showing 55%. So again, up 1% a short while after finishing an activity.

    I did load up the beta software yesterday after reading here about the battery drain. I can't comment on that as I didn't look at that before putting on the update.
