Here’s the official solar-related battery chart of the Fenix 7 series, and how it compares to each iteration from the Fenix 6 series: Entire watch (System): This is a system-wide setting across all sport profiles, and is considered the default for any sport profiles unless otherwise specified All of these workouts are also then transmitted to any 3rd party apps you’ve configured/authorized, including Strava, TrainingPeaks, and other platforms. And all of this data is ultimately synced to Garmin Connect where you can dive into days/weeks/months/years worth of data. For example, here’s my steps data on Garmin Connect Mobile (the smartphone app): A) Day-to-day usage where you just want a flashlight: For example, getting around in darkness, illuminating a small space, surprising someone in the middle of the night with a bright light to their eyes, etc…Basically, the same scenarios you’d use your phone’s flashlight for, except you don’t have to hold your phone

While the thin rim around the Fenix 6 wasn’t as obvious, the much wider rim on the Fenix 7 is clearly visible. Though, I guess I’ve just gotten so used to the look that it doesn’t bother me any. Here’s that identified: Next, there’s now four GPS settings you can choose from (only Sapphire/Titanium editions have Multiband):

Since we know that the sun can power a dead battery (if you leave it out long enough, it’s slow, but it gets there), I’d presume then that the solar charges the battery.

Ultimately though, that’s no different than any other coaching relationship. Some coaches push athletes closer to that edge, and sometimes it works, and sometimes it doesn’t. The results range from winning a race to getting injured. Everyone has different things that do or don’t work for them. All watches in the Fenix 6 and Fenix 7 lines have color memory-in-pixel (MIP) displays. These aren't as bright as the AMOLED screens used by devices like the Garmin Venu 2 and Garmin Epix, but they use significantly less power. This results in longer battery life, which is a big advantage for watches built with extensive GPS use in mind. So, then out of curiosity, I equipped my (much smaller wristed) wife with the same setup again just a few hours later for a workout she was doing later that night. This included the Fenix 7S on her left wrist, a Polar H10 chest strap, and then the Fenix 7X on her right wrist. Keeping in mind, the Fenix 7X is hilariously too big for her tiny wrists. She normally wears a blend of a Fenix 5S (yes, 5S, non-Plus) and a FR945. Here’s that data set: Like any product series, the longer the product is in the market, the less revolutionary the changes to each iteration become. As the product, or even product category, matures – the step-up in changes tends to decrease. While the Fenix 7 is theoretically the 7th generation, in reality, it’s closer to the 8th or 9th generation. There was no Fenix 4, but there was both a Fenix 3HR and Fenix 5 Plus, which were both substantially new generations of devices under the previous generation’s name.Now, there are some notable omissions here, especially coming hot on the heels of the Venu 2 Plus release two weeks ago. There is no voice assistance, or speaker/microphone for making/receiving calls. Even more, despite Garmin releasing the FR945 LTE last spring, there’s no LTE edition of the Fenix 7 either – a seemingly bizarre and odd gap. Nor is there an LTE version of the Epix Gen 2 either. Notably absent though is there’s no wrist-based running power like COROS and Polar have. If you want running power, you’ll need some sort of external sensor – either from a 3rd party (Stryd), or paired with Garmin’s HRM-RUN, HRM-TRI, HRM-PRO, or RD-Pod units – for Garmin’s own running power data field. Nothing has changed there. So, here’s that data set, and at a high level, things look pretty similar. All Fenix 7/Epix/Vertix 2 units were set for multiband GPS, and the FR745 was set for GPS+GLONASS. All the units had no problems in the openness sections: The thin stripe around the edge of the display can collect 100% of the sun’s rays. Well, technically it’s of course less than that, but in terms of simple relativity here, we’ll go with that being 100% from a Garmin spec standpoint. Meanwhile, the portion under the glass can only receive 7% – but the surface area of course is massive. Note that the 7% figure is down from a 10% claim on the Fenix 6, which Garmin explains is because Sapphire is normally less clear than regular glass, so by reducing the solar layer, it increases overall clarity (compared to keeping it at 10%). And of course, the under the glass portion (officially called Power Sapphire, now) is the entire display surface.

In the case of the microphone/speaker, Garmin says that the higher waterproofing standard of the Fenix series (100 meters) versus the Venu 2 series (50 meters), makes this challenging at this time. On the LTE front, I asked Garmin why there was no LTE option given it’s been a while since they launched the theoretically inferior FR945. It was the singular item they provided a ‘no comment’ on, out of the arguably 50-70 questions/details I’ve asked over the past two months. As expected, the Fenix 7’s optical heart-rate monitor lags behind the chest belt for short bursts of intense activity, and its performance for maximum heart rate isn’t quite as good, either, with a difference of 4.3% over those same runs. It’s certainly good enough for most workouts, however. Mapping and navigation related tasks are a big part of the Fenix series, which contains far more mapping/navigation features than you’d likely ever use. For example, there are common ones like following routes, then semi-common ones like creating one-off spontaneous routes, and then lesser-used features like calculating the area of a plot of land. For this review, I’m going to focus on the core route following components including features like the new Up Ahead function, map manager, ClimbPro, and map/route-following practical stuff.Added RealTime Stamina feature, which is used during runs & rides to try and leave nothing in the tank (or, properly manage a workout) I’m surprised that Garmin doesn’t have to designed the watch with this use case in mind. After all, in remote areas, it’s easier to access electricity (or at least a power bank) than reliable mobile internet connection. Then the next night, I threw the same pairing on her again. This time for her indoor bike workout, also then followed by another lift. Here’s the indoor bike: Remember also that you can change the map sets shown. Within the TopoActive map, there are different map layers, including high contrast ones, night ones, even popularity routing (heatmap) ones. I find I tend to prefer the popularity one the most, but the one titled ‘System’ is the default.

Next, note that because the Fenix 7 comes in three different sizes, they *WILL UNQUESTIONABLY* result in different levels of accuracy. As a general rule of thumb, the lighter/smaller a watch is, the more accurate its optical HR sensor will be. Of course, that doesn’t mean a small watch is automatically accurate – but rather the same sensor placed in three different sized watches will almost always result in the smallest unit being the most accurate. Which in turn means that the added weight/size of the Fenix 5X/6X/7X/etc… will usually result in it being the least accurate due to bounce on your wrist. Sync status is difficult to determine and syncing manually seems difficult (or I haven’t figured it out yet). Garmin is hardly the first company here in this space. While Garmin did roll-out multi-band GPS to some of their hand-held devices a year ago, the Fenix 7 & Epix are the first wearables to have it (despite rumors to the contrary, Garmin says the Tactix Delta nor any other wearable from them had multiband prior to this). In any case, the first endurance sports watch to add it was the COROS Vertix 2 this past summer, and then more recently Huawei has touted it in their GT 3. In my testing of the COROS Vertix 2, I didn’t see holy-grail-like results. It wasn’t bad, but it wasn’t the promised land either. Of course, the tech is new, and thus we’re likely to see (and have seen) firmware updates rapidly that’ll improve that. More on that in a minute. In the case of COROS, they’re using the MediaTek/Airoha chipset ( AG3335M), and Garmin confirmed they are also using Airoha as their supplier. Prior to confirmation from Garmin, this made sense in my testing, as in almost every scenario over the last 6-7 weeks, the Vertix 2 and Epix/Fenix 7 units made the exact same errors in virtually identical ways (and inversely, did things correctly in near-identical ways). Garmin also confirmed that both Sapphire and Non-Sapphire units across all Fenix 7 and Epix units are using the same chipset supplier (Airoha). And here’s the red light, which is obviously less bright than white, but also useful when you don’t want the full intensity of white. I’ve actually found the red light more useful at night around the house, than the white light. Merely because it’s much more subdued. Note that even on the lowest white-light settings, it’s still fairly bright, and uses both white LEDs. However, you can adjust that intensity level by going into the flashlight menu. By default you do that by long-holding the controls button (upper left), and selecting the flashlight. But you can also assign a direct shortcut to another button to take you straight to the flashlight controls. Once there, you’ve got the ability to select from four different levels of white brightness, plus one level of red brightness:Meanwhile, for HR accuracy testing I’m typically wearing a chest strap (either the Polar H10 or the Garmin HRM-PRO), as well as another optical HR sensor watch on the bicep (mostly the Polar Verity Sense, as well as the Whoop 4.0 band). Note that the numbers you see in the upper right corner of the charts below are *not* the averages, but rather just the exact point my mouse is sitting over. Note all this data is analyzed using the DCR Analyzer, details here.
