I have the va3 for a long time . never seen such a massive battery drain after software upgrade.the watch dies within less than 24 hours even without any activity. This is totally unacceptable. The watch is almost worthless now. I cannot accept having to plug the watch to a power source twice a day. If garmin cannot fully test a new version before release, at least they should allow the user to choose whether to upgrade. Or at least correct the bug within days. It has been almost 3 weeks since the upgrade.
