Battery Percentage

Agreed.  That would be way more useful than displaying how many miles I've run in the past week.

It's so beyond me why we can't have the battery percentage and the heart rate on the same watch face. At this point you have to guess your battery level.

Some custom watch faces have batt % but I prefer to have the seconds displayed (which custom can't do) so I stuck with the default.

Me too.

I agree. Garmin - please add battery percentage in place of miles. Miles is easily available in Garmin Connect but battery is not.

I use the Forerunner 645 watchface, there I see the seconds and the battery % ( you can tweak the watchface in settings) 

Sure. But, this thread applies only to the Garmin 45 series. My 935 is fine as well. The issue is with the 45. 

We should all tweet at Garmin to change this.

I would like the battery percentage on the face too.  Sometimes, after I charge the watch, the percentage icon stays on the face until I press a button.  I wish it would just stay there all the time.  (see pic)

Agree 100%
