Testing the water: 955 to Fenix 8

so, i did an impulsive thing. as i was anxiously waiting for a Forerunner 975 to come out since January 1, i decided to pull the trigger on a Fenix 8. it's ridiculously expensive, even at the combined 23.5% discount (20% off + stacking some cash back stuff), but i really was tired of forgetting a headlamp and trying to use my phone for a flashlight to pick up the dog's poop at night.

i'm only a day into this experiment;  i have a 30 day window to see if i like it enough (price notwithstanding) or if a Forerunner 975 drops.

i'm hoping i can share some experiences here and potentially answer questions some of you might have if you're thinking about a seismic shift like i am and/or wondering if the rumored (?) upgrades to the 955/965 are of any value.

Background: i've been a Forerunner user since 2011 (FR210) and wearing one as a 24/7 device starting with a 935 in 2017. i appreciated the light weight of these devices that managed to include almost all the Fenix software bells and whistles). i also have been a huge fan of the MIPS face. very subtle yet usable in low light and outdoors. i have historically only used the backlight using the gesture setting between sunset and sunrise. i've been reluctant, like many here, to get on the AMOLED train since i don't need my watch "screaming at me" with it's brightness. 

all in all, my 955 Solar does everything i need it to do for my active lifestyle of running, hiking, cycling, and backpacking. (with random sports in the snow and kayaking thrown in on occasion) the GPS accuracy has been awesome and the Elevate 4 sensor is good enough for most scenarios except spotty for running at times where i have usually used a chest strap, but after getting some wonky results during cold runs (in CA! haha) this winter, i went strapless for several weeks and realized how freeing it was in spite of the mediocre HR data.

So, why would i even upgrade or consider a FR975 (yet to be released), let alone a Fenix 8? Three things: 1. slightly larger screen in the 47mm size (which the 965 has) which is good for these 56 year old eyes, 2. the flashlight -- not for running/hiking per se, but for toilet adventures in the middle of the night and picking up dog poop, 3. the potential of an improved OHR sensor.

Obviously, these a "privileged" desires, not absolutely necessities.

anyway, it's way too early to give a verdict, but here are some initial thoughts:

1. as i suspected, the flashlight is life changing. obviously, i could use a headlamp going to the toilet or walking the dog, but having it on my wrist is so convenient. 

2. i've only done one run, but the Elevate 5 sensor, for my skin/arm is a definite improvement. it seems to respond more quickly to slight changes in effort and while it did do the wonky drop in HR (by about 10 beats) midrrun, unlike my 955 (which would do the same thing regularly), it corrected itself after a minute whereas the 955 would keep at the at lower HR. 

3. the AMOLED screen: while i still need to get used to the brighter screen, setting it at 1/3 brightness has worked well and i daresay, the AOD dimmed mode is perfect for my indoor uses of glancing at the time/data without having to move my wrist (while typing this, for example).

moreover, the screen size and pixel density is a game changer for my old eyes. i find the "6 data field" screen is much more readable while running. i think this is a combination of not just the higher pixel density and 0.1" bigger screen, but also the font utilized by Garmin on the Fenix 8 vs the 955. i am guessing one would see this similar improvement on the 965*.

4. i'm using the Fenix 8 with an ultrafit band (same one as my 955) and it is comfortable, but the extra 17 grams of case weight is noticeable. i'm a day in now, and i'm noticing the weight difference less even after only 24 hours. thankfully, i didn't think it was uncomfortable to sleep with which was my initial concern.

5. build quality: most people say the Fenix series is so much more robust. while i think the materials are more premium (and heavy!), i would argue that cosmetically, the FR series may be more tolerant of abuse (case, not screen): none of my previously mentioned FR's looked significantly beat up after many years of use and banging into walls or while working on the car. i'm pretty sure i will scratch the titanium on the Fenix 8 before i know it although such blemishes can be polished out. the FR series to me are very durable and impervious to getting blemishes in time to the casing.

6. battery life looks like it will be consistent with what reviewers have suggested. i am guessing that with my low brightness setting and AOD turned off while sleeping, it is good for 10 days of smart watch usage, or 7 days with my typical 6 hours of GPS activity + 3 hours of strength training (no GPS). i'll likely charge every 6 days or so to keep the battery level above 20%.

anyway, those are some initial thoughts. i'm not 100% convinced i'll keep the watch. if a 975 with an Elevate 5 sensor and flashlight comes out in the next 1-2 weeks, i would seriously consider returning this Fenix and going for the lighter watch at what i would anticipate being a lower price, even accounting for the significant discount i bought the F8 at.

are any of you in the same place i've been recently? hankering for a flashlight and newer HR sensor? if so, shoot me questions here or directly. happy to share my experiences and answer any questions.

*ps. i never gave the 965 serious consideration because i couldn't justify the lateral upgrade for just the screen (which i wasn't sure i would want to adopt after years of MIPS use) and i didn't like the domed screen not being able to take a flat tempered glass protector.

  • I was somehow in your shoes, in that I took a sweet deal on a Fenix 7 Pro before finally settling for the FR955 last August. I only missed the flashlight, and find the 955 much better for what I use it. The software is also more polished, whereas on the Fenix it used to lag from time to time and sometimes reboot mid-workout. Being lighter certainly is a welcome change, although Fenix design is more appealing. I won't miss Garmin's failed software updates once they will stop coming, most of the time they are riddled with bugs, so another advantage of having an older watch. All in all, there is no other Garmin watch I would upgrade to, so the 955 is the end of the line for my relationship with Garmin. Once this dies or Apple launches a better Pro (I hope for a round design, but I know it won't happen) I will leave Garmin and probably not look back.

  • I agree with many of your frustrations. you came to the FR955 at the right time. I bought it at launch in June 2022 and it was very bug ridden (moreso than my 935 and 945LTE) for many months. I would say the turning point came at around 1 year time. after which, at least for me, I got the watch "I paid for" (ie, feature set and no major problems). I'm buying this Fenix 8 7 months after release and thankfully, most of the major bugs have been ironed out. it's too early to tell, but I've only encountered one bug so far that is frustrating me and has been reported by others.

    I too would be hard pressed to go with an Apple Watch due to its shape and short battery life. 

    in reality, the 955 could be my "last watch" as long as it doesn't/didn't break. same goes for the Fenix 8. they both have all the features and metrics I want, plenty of battery life for my backpacking adventures, maps, and multi band GPS. I can't imagine what features Garmin will come up with in the years ahead (LTE coming back? wireless charging?), but these watches have matured much like smart phones.

  • [rebooting mid workout must have been awful! I thankfully have never experienced that with any of my Garmin watches]

    I had that a few times with a vivoactive 3. It would then give me an insane amount of elevation gain during that activity!

  • Ironically, I have never had issues with the Vivoactive 3. Same with the Vivoactive 4 until an update screwed up the battery as many people complain in the dedicated forum. And I am now on 22.22 sw on the 955, also no issues to report.  But I choose my updates carefully (vivo devices wouldn't allow deferring updates).

  • I switched from 955 Solar to Descent MK3i. Was supposed to buy this as dive only watch, but the AMOLED was just too nice to not use every day. Idea was to upgrade daily watch to later to like Fenix 8 or something. Fenix 8 had just nothing really I would want coming from Descent. 

    Maybe Forerunner 975 gets me back to Forerunner camp. We'll see.

    Ps. I would just disable the AOD, I at least get used to it really fast that you don't try to side glance watch. 

  • good insights and experiences.

    I prefer to be able to see the screen at a glance and AOD is working well for me. I'm now almost exactly 4 days in with AOD and futzing around a lot with watch faces and settings and sitting at 50% which includes 4 hours of GPS running (But Select) + 2 hours of strength training. very pleased with this battery endurance. if I were wanting to extend battery life on a backpacking trip, I'd definitely consider going to Gesture only as I don't need to "glance" in such a scenario.

  • one update 4 days in on the Fenix 8: for my skin/arm, the Elevate 5 appears to be a marked improvement over the Elevate 4 sensor.. the E4 was no slouch, but I would find that every 1 run out of 3, it would lock in at a lower HR (about 10 beats low) and stay there until I stopped running. I've done 3 runs on the Fenix 8 so far (4 hours total), and the data is more steady and doesn't misbehave like the E4. I did some one occasion of the same behavior of the HR dropping about 10 beats, but after about a minute, it went back to where it should be. also, while I'm sure inadequate for interval work, anecdotally, the HR seems to adjust more quickly to slight changes in speed with the latest sensor.

  •  some questions from a current 955 owner:

    1. Would you say the general performance (e.g. menu navigation, loading, saving something) is the same on F8 or slower than 955? I am asking since the F8 appears to have the same CPU and needs to drive more pixels. 
    2. What about the map in particular - is the drawing / rotation similar or slower?
    3. Some people seem to be annoyed by the slow gesture reaction (screen switching on) - do you agree? In particular i am worried during e.g. trail running it might be too slow to quickly glance at the map
    4. How fine-granular can "always on" be tuned? Can i have AOD for some activities only, but not for all? Or off for general use and on for activities?
    5. In case you have the sapphire version - are additional reflections noticeable vs. 955?

    Thanks in advance!

  • hi ,

    1. overall performance seems comparable between the watches, running the latest FW13.35. it came with FW10.XX and it seemed sluggish on that version. but I have no complaints after using the later version. I have some suspicion that while the chipset may be similar, there may be some tweaks and mods made for the AMOLED watches in terms of the graphics part of the SOC.

    2. I haven't used the maps enough say definitely whether one is faster or slower. I just did a quick test of zooming in and out and I think the interface for zooming is much better on the Fenix 8. redraw may be slightly slower, but nothing that bothers me. I think if you look at some of the review videos you can get a feel for whether the redraw/update rate is fast enough for your liking.

    3. it's interesting that you ask this. I have several anecdotes to share...

    - I have been using AOD with the watch face and general use and gesture mode works well for bringing it up to full brightness. it works similarly to how I had my backlight set for gesture mode between sunset and sunrise on the 955. it works flawlessly for me.

    - I did 3 runs with the same AOD mode (4 hours worth) and gesture mode worked perfectly for me. I didn't use maps however, just data pages.

    - today, just in the interest of trying to maximize battery life, I experimented with turning off AOD and using gesture only for my 1 hour run. this experience I did not like at all. while it worked 95% of the time, I felt it was slow to bring me the data/light up the screen. maybe because it had to start from a black screen rather than a dimmed state? or maybe my eyes interpolates the ramp up of brightness in the AOD state. anyway, I definitely will be using AOD for running in the future. I imagine while backpacking/hiking to save battery life, I might try gesture mode (AOD off) because I'm not trying to get my info fast like I am while running.

    4. I haven't played with this yet, but I am pretty sure you can fine tune things by sport because there is a "power mode" that you can couple with each activity. I haven't played with this yet as I haven't needed to (I've only done runs thus far and strength training), but at least on paper, you should be able to customize AOD per activity if you create a power mode for it. (it comes with a bunch of default ones like max battery, max accuracy, sleeve, and a couple others.... ie, the power mode not only sets display behavior, but also GPS bands, wrist OHR and other things)

    5. I do have the sapphire version and it does have more reflections than my 955 Solar (which I covered with tempered glass) but nothing that bothers me. I can see my watch face at a glance indoors at my desk during the day (which was what I was most concerned about) and I can read the screen quite well, even in the full sun even though my brightness is set to 1/3. however, I should note that outdoors in the sun, the AOD "dimmed state" is almost invisible so a gesture is needed to make the screen bright enough for things to be read. for my use case, this is perfectly fine. but for others, that might be an issue.

    hope these help and feel free to ask more questions. if you have a retailer or can buy from Garmin.com in a way that allows you 30 days to return it, I'd suggest doing so. I'm glad I decided to do this "experiment."

    at this stage (day 5), unless a great Forerunner 975 gets released soon, I'll keep the Fenix 8. it's not perfect (a couple of bugs which are annoying, but not show stopping), but I like it a lot, price notwithstanding. I've gotten used to the weight for the most part, I like the looks, it's battery life is almost as good as my 955 Solar for regular use even with AOD mode turned on. I anticipate a 6-7 day charge cycle vs 8-9 on the 955 which is more than good enough.  the Solar certainly wins for backpacking although I will very likely turn off AOD to extend the F8's battery endurance my typical 4-5 day backpacking trip).

    more striking, four runs in, the Elevate 5 sensor is proving capable enough to allow me to run with out a chest strap. typically, I am not worried about any nuances. at my old age, I rarely do any sort of interval training, so I don't need ultra fast response to the HR. it's very freeing to run without a strap. YMMV with Elevate 5. for some, I know Elevate 3 and 4 were already good enough for them. those two gave me good data 90% of the time but they would occasionally do weird things. nothing encountered with the Elevate 5 so far except for one minute of depressed HR over 5 hours of running which is a huge improvement over the 955 sensor for me.

    the 955 is still a fantastic watch. this Fenix 8 was an impulse purchase of sorts to get the flashlight (which I use daily), but certainly not a necessity.

    i'd be curious what your reasons for upgrading would be.
