After software update, my Standard Instinct now always shows full battery life even when it does not have full battery life

Last week when I woke up, I noticed that my watch face said that my watch software updated automatically during the night.  The battery life magically went from 3 or 4 bars to the full 5 (without charging it).  After a few days of wondering what on earth was going on, I had the bright idea to restart the watch.  After a restart, it will indeed show the true battery life (less than the full 5 bars).  But, within a few minutes, it starts creeping back up, one bar at a time until it is back to showing the full 5 bars.  I know that there are other threads on here about this exact same issue.  The problem is that I have yet to see one thread with any kind of resolution or solution.  I have not even had the watch for 6 months (it was a Christmas present).  Now, I have to constantly restart my watch just to see the battery life.  This is disappointing and inconvenient to say the least.  I suppose I will try to contact Garmin support to see what they say about the matter.  I do think that it is a software problem since it seems to line up with the update.
