Solar Charge Test: Your experience?

Hi everyone, have any of you carried out any tests regarding solar charging? I have a Fenix ​​7X Solar and today I think I have charged it for several hours.

In the first hour, the sun was far from the balcony, so I couldn't see the effects well.

In the next two hours I walked to the beach, recharging the watch but it was not in power save mode and no activity (simply walking on the beach with the watch on my wrist) .

In the last two, however, the phone was in power mode and the sun was almost always at 100%.

The charge was 89% since I started testing at the begin of the day. Then, I turned off the watch for a moment (thinking that something not work) and turned it on again, it was at 90%.

In total today I have stored 247k lux / hour.

Is this normal behavior?

I have had a Garmin Instinct Solar in the past, which would have recharged at least 3-4%.

In the next few days, when the sun will be strong, I will carry out new tests.

However, I leave attached a photo of the solar charge.

What are your experiences and what do you think of mine?

  • Desfit did it with the fenix 6 solar. Twice actually, because the first time his experiment was a bit flawed, so he did it again.

    Anyways, the fact is nobody really wants to bother testing this in that way. It's an unrealistic test because it doesn't represent how the watch will actually be used in reality.

    I've got a 7X Solar and would love to do a controlled test to see how the solar works, but honestly why would I bother, I didn't buy my watch just so I could take it out to the backyard and lay it out in the sun. If someone else wants to do the test, I'll happily read their results, but I have other things I'd rather be doing than making science experiments with my watch's solar panel.

  • I would just love someone to test the 7x Solar to see if it'll actually increase battery % if left in the sun for a few hours.

    All my GF6XPS would do is maintain the battery % if I had outside for 4 hours is maintain %, not increase charge.

    I would see no reason for me to update from GF6XPS to GF7XPS unless the extra size of the solar panel on 7XPS would actually increase battery %.

  • I would see no reason for me to update from GF6XPS to GF7XPS unless the extra size of the solar panel on 7XPS would actually increase battery %.

    I would suggest that anyone expecting to see the battery gain charge during use from a F7X will be disappointed. This might happen if the watch was left unused in bright sunlight for a number of hours but as already noted that would not be expected to be a normal use case. 

  • The solar functionality mainly reduce the battery consumption during an activity.

  • Living in the UK without much sun, I see the Solar feature as totally pointless. I wish Garmin would offer a Sapphire version with 32gb and all the maps WITHOUT the solar option. 

  • Or a 7x with the antireflective coated Gorilla-glas of the Forerunnter 945 :-))

    I would buy it instantly

  • The only reason to buy f7 over 6 is improvement on solar capabilities at least to me so i need someone to test that

  • You're right it makes no sense to leave your 10k watch outside for hours to see if it charges but that's not the point what if you go somewhere for 4 to 5 days with 10% battery and forgot the charging cable ?

    That 2% solar charge may not enough for activities or GPS workouts but you can at least use your watch as a "watch" until you get home

  • I think no one bought the watch to leave it in the sun to "tan" :)

    But they are still tests that one carries out out of curiosity, as the other functions of this Smartwatch are tested.

    However, I tell you mine having worn it and recharged it in the sun: the battery remained at 89% for three days, even the count of the remaining days remained at 30 despite the fact that 3 days had passed.

    This means that maybe the battery percentage remains the same, but solar charging still greatly increases the duration of this.

    Tomorrow I will see how it behaves in an outdoor trek, and how much I will consume from a battery point of view with an activity.

  • Ok I'll appreciate it if you report it back?
