Venu 2s keeps switching itself off

Same symptoms as my Venu 2S which is 2.75 years old. I read here that since it is out of warranty, the best Garmin can do is to offer a refurbished one for $140 USD. 

I'm disappointed as I thought the Garmin watch would exceed my experience with Fitbits which lasts about 2 years. I mean amortizing the cost of the Garmin, it's about $10/month over its useful life. Seems silly to spend $300 or more every couple years for a fitness watch. Who knows, maybe none of them are built to last. 

With that realization and after fudging with the 2S for the last several weeks to no avail, I bought an Amazfit Active 2 today for less than $100. It has comparable features and I won't feel as bad if it dies after 2.75 years (for less than $100!). I have been pleasantly surprised by it's design and usability so far. But once again, all of my historical fitness data will be locked up on a platform I am leaving. 

Hi - well I think there is reason for optimism - I was contacted directly by the support team and was asked to upload the systemfiles for teoubleshooting of the software - I did that and now the Garmin team is looking at the systemic error - I am sure Garmin will fix this so we can all trust their software and equipment …

Thanks for letting us know. I'm a little skeptical Garmin will resolve this for device users out of warranty anyhow but keeping an open mind. I suspect that the issue may have something to do with the device's water resistance ability because my Garmin tends to crap out when I am out on a moderate walk or activity. I don't notice this much at home when i am sedentary. On top of that, I see this issue was repeatedly reported in this forum from at least 8 months ago!
