I‘m running various tests on all different kinds of LTE Galaxy watches (some on Tizen 4.0.0.7, some on Tizen 5.5.0.1). As soon as I configure an eSIM on those models, they all are running out of battery after about only half a day. They all draw about 10% of the battery per hour. The important thing to note is that I‘m running the watches in standalone mode, ie. without any paired phone that could be used to route the connections through (which would be much more power efficient I guess).
Is it really expected that the Galaxy watches are sucking that much battery power when running with LTE in standalone mode? I was hoping to get about one full day of battery life at least.
