Some questions about solar charging on I3 Tactical

I think you should tamper your expectations with the I3's solar capabilities. From my experience, and from what I've read here in this subreddit, solar charging is a utility used mostly to "delay" the watch from dying. But there are also so many other variables at play: How high is your brightness?

Battery life/drain - instinct 3 solar 45mm

Reed Works and Mobile Driveway have far more data and feedback than you ever will, and they’ve heard lots of complaints about this issue.I
