Constant Voicemail "Received on Watch"

I've had this issue for a while and I'm surprised the solutions are so complex. My personal experience with T-Mobile over the phone has been very time consuming and with mixed results…. Generally the more time spent after they mix up something with my account, the closer I can get to breaking even or maybe actually solving the original issue, solving the new issue and getting some sort of credit to my account that made my time worthwhile. (And I'm talking about hours on hold, random disconnects, no record whatsoever of multiple prior conversations on my account with one rep, then everything there with the next, etc.).

I actually resolved this issue for a few days on my own, but don’t recall how exactly (pretty sure you just need to use the watch to delete a voicemail from the phone through to completion, and it’s gone). 

That's no good for someone like me who always has some saved voicemails, use the spam blocking, which is a whole other world of chaos (btw it works, and it's free if you already have VM-to-Text), so I still receive VM without my phone ringing and it may even be true that I got a VM on my watch without getting it on the phone like it thinks. But it doesn't matter because you still have to go through the watch to access VM and delete, and next thing you know, the battery is dead.

I have a Galaxy Classic4 and I really just needed a watch with some sort of notification ability, and this was the simplest solution . Unfortunately I simply cannot comprehend how a watch with activity tracking and sleep tracking can be sold, period, when you cannot use either one of those features more than once before recharging the watch. I.e. Sleep tracking is probably for when you're not active, I'm presuming from the name that it's for while you're sleeping, and all the other features are obviously for (just a guess) use when you are not asleep, like turning the dial, perhaps even doing a physical activity. So this may be hard for someone in Marketing at Samsung to follow, but if it takes more than (conservatively) 30-60 minutes to shower, etc & charge the watch, then the charging time is taking away from it's usefulness for wearing it. Plain and simple I have mine on Power Save, barely use my watch to even check the time, and spend about 4 hours over 2 days giving it enough time to charge. I can split it up into smaller increments over more days, but the point is that this watch is useless for using 2 of the most basic functions WITH power save on. 

The process of taking the watch out of power save, turning on everything you need to get rid of the VM message, and getting back to where you started uses up about 15% of the battery life right there. (Minimum of 20 minutes charging to get that back.) Am I just not used to wearing a true Smart Watch?

The VM issue really bothers me, but seriously, if you check your VM with your watch (and don't have the VM icon on your phone on - or maybe you can, as it should go away), the moment you actually get to the prompts and follow through with the tiny keyboard (I don't do the voice thing, yet) the notification will go away. It will come back though if you reboot or possibly break off the connection with your watch  & phone, depending on the options selected. It always comes back, and the entire process of enabling everything just to get to the VM through the watch take time and a lot of battery power (more time). So I guess my point is that (and I got the bigger Classic4 BECASUSE of the battery issues people mentioned with the smaller one), something has to be done regarding the battery longevity on my watch at least, because I'm used to the annoying notification knowing the tradeoff is even more precious time. Which is funny, considering...
