2X Solar Tactical vs I3 Solar Tactical

The 2x is heavier and that can impact data. There will also be software limitations as Garmin is still updating the I3.

Continuous loss of mobile connection

I have the same problem today. From time to time the connection drops and I can't reconnect. The only thing that helps is reconnecting to the phone via Garmin Connect, like the first time I connected it. Instinct 3 Solar, 10 days after purchase, firmware version 10.36.

Battery dies in 24h

Hmm yeah, I checked all the links people commented and all the complaints people have made about their battery are exactly the same as mine. I saw some people fixed it by installing an earlier software so will try that. FYI: I contacted Garmin support and their only response was that they couldn't d

Instinct 3 Solar 12.17 beta Fixed possible battery drain when using CIQ watch faces.

I was the first person to report this bug on the Garmin forum. But Garmin hasn’t even responded to the post! This watch has had many issues since launch and it’s still unfinished. I’m completely fed up with Garmin now. https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/instinct-3/4237

Officially joined the club

Yeah, I'm on 5.21 and have been since it was new. I was just interested to see if they're being updated before being shipped from Garmin. There are a few more updates available but need to be done via Garmin express. I believe there is a bug with the i3 solar where it says it's up to date and no upd

Hesitant to buy

If you take a Fenix 7 Pro or Fenix 8 Solar, then the move is good. But the Instinct 3 Solar is a bad model (take a look at it storage 128Mb storage which could be a problem for System upgrade) Otherwise, i personally switch from Fenix 7Xss to Coros Nomad, it's a perfect price/feature product. This t

Garmin Instinct Solar 3 stuck on 5.21 and none of the forum solutions worked (Solved)

Can this be done at any stage over the air? I have only a work laptop that won't allow access to Garmin express. I have i3 solar 50mm stuck on 5.21.

Firmware issues with new Instinct 3 Solar (50mm)

I just wanted to share my experience (FIXED). I was in the same boat - new I3 Solar with firmware 5.21 out of the box. Actually my Software version was 0.00, and Host version was 5.21 on the watch. None of the advice online helped:- on the watch and in Garmin Connect there was no option to 'Check fo

HELP?? garmin instinct 3 solar tactical won't connect to phone

I have an i3 and an android 13 phone. I've given up trying to keep them connected. Garmin Support can't figure it out either. And yeah, the initial pairing almost always failed. That took forever to work. I think it is a clash of power-management strategies that I cannot (figure out how to) override
