Abnormal battery consumption (4 days instead of 14+)

Same here. Fully charged on Saturday, now 58% battery remain. 

I had _similar_ issue, except that it started on the day I installed a firmware update. So it was very clear even for a child that the FW caused it. Unfortunately Garmin support dismissed it. They point to things that haven't changed for half a year (i.e number of installed ciq apps) 

You can try your luck contacting support, in my experience it somewhat depends on which agent you fall (and maybe also with which leg they started the day) and they might offer a replacement, though not very likely. To me she said that she too has 5 days of battery time, so I am fine. The advertised 20+ days is so "high" relative to real life that they ignore every mention of it. Maybe their chat software removed sentences mentioning it...  Also for sure at some point they'll tell you to do a factory reset, which in 99% of the cases has only one effect: wastes the user's time and nerves. With some luck your watch might be the 1%

Firstly, turn off Always on Display. (System>Display>General Use>AoD). That uses a lot.

Turn down the brightness. there are three levels.  the 2nd level is plenty bright, and the first level is really nice and less obnoxious

the long battery life, is only if you don't use the GPS.  

Unless you really need it, turn the GPS to "GPS Only" or "all Systems".  ( you need to do this individually in each activity profile)

and- if you get a lot of notifications from your phone, the vibration uses some extra energy too.  So, perhaps turn off all those that aren't necessary for you.

if you're still sucking battery, you could just have a defective battery or unit somehow.  if so, then call Garmin.  they'll probably coach you through settings, and then if all is still not good, probably send you a new, refurb unit.

All this is nice, but disregards reality and facts. I had my settings (whatever they are, irrelevant to this thread) not changed for more than 6 months, and suddenly THEY (the settings) started to cause battery problems which accidentally started on the day I upgraded the firmware!? Come on, unless you work in G., you must admit, that this makes no sense! If there's only 1 thing that changed (FW version) then it must have caused the battery issues.

Furthermore, after the problem started and spoke to some G. agent who also didn't think (probably also didn't read my messages further the BATTERY word) told me the same nonsense I did everything they told me. Turned off AOD, which might have increased the battery life from 5 to 7 days, but still far from what has been prior to the FW upgrade.

Furthermore: changing the CIQ watchface that I used for months to one of the useless built-in watchfaces did not change anything (maybe added 1 day)

So now I ask: please reason now and explain how my settings are causing the problem and how not the firmware upgrade?

You mean removing that file improved you battery life by at least 1 day in average? Hard to believe, but on the other hand it's Garmin, so who knows.

Please keep us updated on this!

Let's see in a couple of days, my gauge still claims 100% after 12 hours since full charge...

Same here. And I also have some wierd charging issues. It's says e.g. 100% when the watch is in the charger - soft reset and it drops to 90% or lower (it does not have to be fully charged i.e. that "initial" drop happens anyways  - and that also started after firmware 19.18).  Same exercise routines, same settings, same stock watch face, same external sensors, same me - just higher battery consumption and that drop. And NO - hard reset cannot be the answer to every phenomena caused by sw bugs.
