Lasts me about 2-3 weeks, I run 30-60 minutes each day and also track a 30-60 min strength workout. I disable most notifications, only work Slack and messages from my wife.
It depends on how much time you spend outside in the sun. If you never go outside, it should get you 28 days in Smartwatch mode, if you spend at least three hours in peak sunlight, then it should charge enough that it never dies. (source: https://www.dcrainmaker.com/2025/...solar.html)
In the real world, it depends on how heavily you use the smartwatch, backlight settings, etc. but certainly I would expect 20-30 days without needing to charge even without solar charging. For a normal person who spends some time outside, I could see a few months, for people who work outdoors, then this is like a solar G-Shock that won't need to be charged until the battery starts failing like five years from now.
I have HR on and get notifications from text and calls. I workout for 6 days a week for ~45 minutes. I get ~35 texts a day, and it lasts about 3 weeks. Auto light is on, minimal torch use. I set sleep from 10:30pm to 6:30 but often the alarm is set for 6am.

I think the "never dies" reviews are for the 50mm version. I have the 45mm and agree that 2-3 weeks is normal unless you use GPS a lot.
This is a great watch. Paired with the explore app and offline maps, it was very helpful for navigating trails at Philmont Scout Ranch without having a Fenix with full maps (adults aren't supposed to navigate anyway so that the scouts get to learn navigation skills, but it was helpful to know if we got off track very far).
I never missed the color features from my old watch. I did switch phones from Android to iphone and can no longer reply to text messages from my watch which is a bummer.

I get very little solar help.
