Just got myself an Instinct Solar Tactical a couple days ago. One of the things I noticed recently after charging it (i don't have a wall adapter, so I'm using my PC to charge it for now) is that the battery levels dropped 2 days from full charge each day. I was wondering whether this is normal. I don't know if this is gonna help my case but I also did a software update to 19.01 the night I got my watch.
