Thanks for this test and your findings. I was doing quick math before with info that Garmin claims on its website - up to 15 days / 20 days in solar mode with 3 hrs solar charging daily. Quick math - 100/15=6,67 and 100/20=5 1,67/3 is 0,556 per hour which is kinda in match with your findings. So thanks for confirming it :) Metal Watch Band Adjustment.

No matter how many times I plugged it in it always began charging straight away (had to test it thoroughly, you know). So, the Garmin supplied charging cord appears to be faulty. Garmin Fenix 7 and aftermarket Don't utilize GPS much at all, spo2 manual check only, still charging it once a week, maaaybe 1.5 weeks. Nowhere near the 25+days expected. When you are fully charged, what is the battery estimate 10 days or 28 days or something in between. Its a quick way of identifying if its a setting that is causing the issue. The battery level does not change but it remains for a much longer time the same. As very rough estimation I would say that about 80kLux/h is equivalent to 1% battery charge for my configuration.

My personal impression is that the solar functionality is only working if the current power consumption of the watch is lower than the current hi guys, about 1.5 month ago I bought Fenix 7x Sapphire Solar version as an replacement for my old Fenix 3. during that period of time I had a chance to use it mostly as a smart watch (with 24/7 HRM on and SpO2 measurements during sleep) with 3x 1h sessions in gym per week. with default watch face, no extra apps whatsoever. with that usage I'm getting about 16-17 days of use on a single charge Meet any athletic or outdoor challenge with the rugged fēnix 7 Sapphire Solar multisport GPS watch.
