Instinct solar Powers off randomly

My watch has done the same for the last month - randomly turns itself off despite having more than 10 days charge left - it is an expensive Solar model I bought last year after my previous Garmin's batter life decreased to next to nothing after less than 3 years use - time to try another supplier.

Even i face the same issue. Power will be like 60% + and then it switch off randomly.

I also noticed this power off problem when i try to run the Pulse Ox manually. Sometimes the Power On button do not work post these kind of shutdown. Either I have to connect the Power cable or I have to press Left Upper two buttons together to switch on the watch. 

This started recently only

Hello.

For a month, my instinct solar (fw 18.54) randomisés powers off, but sometime it’s not random. When i want to start an activity, especially with Treadmill Running.

One month with such bugs it’s kinda long.

Let me add that i have made a reboot, a reset and a factors reset without succes.

I hope it will be better with a new update. 

Mines is exactly the same, i'm gutted! Its only a year old, been great up until the last few wks, but now it turns itself off more often when i'm recording an activity. Cost me £229 and i'm feeling robbed now

I've returned my one under warranty to Amazon - it will take 10 days to get back which is annoying - tried all the suggested 'fixes' but still powered off randomly - seems lots of people are having the same issue, maybe Garmin should consider a recall of the Solar ?

I am sorry you have an issue. Regarding your comment, the restart issue remains rare and is not common. My sincere apologies you have had to exchange your watch.

I also have this problem. It first shut off when there was 7+ days of battery. I was not able to turn it back on or charge it. I gave up on it for a month then tried again. This time it charged and turned on. It worked for about 30minutes with 27+ days battery life on screen, then shut off when it went to pulse ox (automatically). I plugged it back in and it didn’t charge right away. After a while I checked and it was back on. Unplugged and it turned off again. I’ve considered trying to get a new battery if one is available but I’m not confident that’s the issue. I think Garmin should have a solution for it by now and acknowledge it is a problem they need to look into. I’ve had the watch for 2 years so it’s past the warranty. Surely it should last longer than 2 years under normal use right? Disappointing.

Mines is under a year old but i no longer have the  receipt, the watch  has been fantastic up until very recently. I've rebooted etc as garmin advise but even this morning's walk , it again switched off . Surely its repairable as i refuse to shell out cash for another
