"offers significantly better battery life ... insane battery life"
"I been using mine for two month. I just charged it for the second time and its holding up great."
"I have had it on for 25d and it's still got 6% battery. That's what I'd call a watch!"

"the screen, which is not the awful LCD/LED stuff that most watches have. It's clear in all conditions, and extremely durable."
"rugged enough to take some hits at the gym."
"The Instinct 3 is built tough (rugged, reliable) ... If you’ll drop it, bang it, leave it in harsh places, the Instinct’s durability becomes appealing"

"Had a 4 mile swim in a lake that looked pretty accurate, way better than I expected."
"It lasted the whole trip on a single charge which including 75 hours of tracking with 43 hours of movement."
"it works perfectly for what you want!"

"The sleep score and body battery is a game changer - It is insane how much this has helped me with better habits in just 6-weeks. ... I can see the difference in my sleep and body battery even if I have two alcoholic drinks at an event or with dinner, or if I have too much caffeine too late in the day. It is helping me understand the effects of these actions on other parts of my life more explicitly."
"The Garmin excels at all of that ... I wear a smart watch to gather my health stats; steps, floors, calories, heart rate etc, and also to get a good measure of my sleep."
"I only really use it for HR, steps and sleep tracking."

"Without even really changing much settings on the watch to preserve battery other then disconnecting it from my phone I get 4 days of gps recording when backpacking. ... I get 4 days of gps recording when backpacking 6-8hr days on my instinct 3 solar 45mm."
"Had a 4 mile swim in a lake that looked pretty accurate, way better than I expected."
"Incredible battery life. ... That is with full GPS use over 30-48 hours. ... I am sure the watch can be switched to battery saver mode when sleeping or not actively using the GPS so it can stretch out a few more days."

"Garmin surprisingly messy ... Garmin was all over the place with noisy spikes. ... Garmin Instinct 3 really surprised me with how messy the HR data was. I am very negatively surprised with these results. ... I was really surprised with Garmin, and I am thinking it might have been not tight enough. I have the 50mm version and it is quite bulky, which probably causes a lot of movement, that probably interferes with the reading."
"Garmin has been failing at HR data for a while now, you need a chest stra for activities to get good data."
"In my experience the heart rate monitor on the device itself is average at best."

"the problem with the maps is that there aren't any. ... The breadcrumb think can work ok in the city, especially if you have a backup device, and not for cycling. Super hard on hiking trails that tend to have forks as opposed to really distinct, right-angle intersections."
"not having maps will not be great for hikes."
"no maps though ... If maps are big for you though I would recommend the Forerunner 265 and higher or the Fenix series watches."

"But those are a fair bit bulkier."
"It's definitely a bulk "rugged" watch"
"50mm i3 is probably to bulky for swim"

"The UI is so bad - I can't believe a massive company such as Garmin has mid-2010's UI on both the watch and Garmin app. The graphs, data presentation and navigation is about 1000 points lower than Apple Health. It is so unappealing it looks like it was created by an accountant. ... I should have focussed more on the UI on the Garmin app - that is mostly my issue. I dont find the Watch UI too clunky but the Garmen App UI seems pretty behind the times."
"But then you don't get the most out of it until you export the data to Strava or similar as the Garmin app is not great."
Epix pro gen 2 51mm and instinct 3 solar 50mm. One AMOLED and one SOLAR I like both screens.
r/Garmin • Do you have more than one Garmin watches for your activities? ->Garmin instinct crossover, 28 days battery life, 50 without constant hr measurement. Instinct 2x and instinct 3 solar 50mm have 40 days battery life, 70 without hr. And solar charging.
r/smartwatch • Best smartwatch with decent battery life ->I downgraded to instinct 3 solar, because I want MIP and the instinct MIP screen is very bright. And because of battery life: 28 days in smartwatch mode in a 45mm case! And because it's much more comfortable to wear than a Fenix, is more resistant to scratches... I only (rarely) miss offline maps. But the breadcrumb navigation is great and much clearer to see than on the color MIP screen of the fenix I used to use.
r/Garmin • Garmin fenix 8 pro is a bit underwhelming to me,what are your thoughts. Am I wrong? ->Instinct has no maps. Enduro has maps and has a MIP screen. The Enduro maps are harder to see than the Instinct breadcrumb, because of several reasons: * the Enduro screen is dimmer, due to 1) colors, 2) sapphire * the breadcrumb trail is clearer, because it's high contrast black and white, while the Enduro trail is pink-purplish on a colored maps with lots of things going on. The picture show the difference. https://preview.redd.it/nzt2o5c9a4nf1.jpeg?width=2814&format=pjpg&auto=webp&s=e952c703a2cc52dd3f73f6cf0b4a88829ac0a397
r/Garmin • Garmin fenix 8 pro is a bit underwhelming to me,what are your thoughts. Am I wrong? ->The instinct had no touch screen. What actually makes the tactix 7dimmer is this: sapphire crystal, solar panel on top of the screen, colour screen, and maybe higher resolution. Maybe the touch screen too, but I don't think so.
r/Garmin • Garmin fenix 8 pro is a bit underwhelming to me,what are your thoughts. Am I wrong? ->Enduro 3 is simply the king of Garmin’s line up at the moment. No question. Unless you need the dive / speaker stuff I’d be going for that. The 7X PRO Solar sapphire is a great second. Instinct 3X Solar takes the third spot. I’m a bit sceptical of Garmins future, kinda feels like they have peaked with the enduro 3. MIPS could be gone. Garmin connect plus. MICROLED 8 Pro at 2k USD with a 4 Day Battery. The buggy firmware. The terrible way they have rolled out LTE / Satellite. Their best days may be behind them.
r/Garmin • Best Garmin Watch on the Market Right Now? ->From my quick 5 second search, tattoos will be a problem for all optical HR sensors so a Garmin watch will be just as problematic as an Apple watch if worn on a tattooed area. So a chest strap + bike computer would probably be a better idea. For me personally when I'm not tattooed yet, my Instinct 3 works perfectly for cycling.
r/Garmin • Considering getting a Garmin watch for cycling. ->Instinct 3 Solar. -6% in 80 hours after my first full charge so I estimate at least a month. I really need to update my software version so the watch itself can estimate it's battery life. It's just stuck at 11 days for now.
r/Garmin • What’s everyone’s real world battery life looking like? ->I have the 3 Solar 50 mm. It tracks HRV, It works well for overall fitness tracking like any other Garmin watch. In 15 days since last full charge it went down to 44% so if you do more activity tracking it should hold for like 3 weeks.
r/Garmininstinct • Instinct 3 mainly as a sports tracker ->Agreed. Worst thing ever is continuing to research after a purchase. It's how I went on a return & exchange spree from a 45mm Instinct Solar to an Instinct 2X to a Forerunner 570 47mm to an Instinct 3 Solar 50mm to a Fenix 8 AMOLED 51mm to ultimately a Fenix 8 Pro 51mm. I'm settled now. Because I've stopped researching.
r/GarminWatches • Fenix 8 Sizing/Display Advice ->Garmin Instinct 3 solar, 50mm, or Instinct E if you are tight on budget. Works with Healthy365 and has impressive battery life. Expensive, but long lasting. (I got my first gen instinct lasted for 5 years before switching to the current Instinct3)
r/askSingapore • Best budget fitness tracker that works with Healthy 365 ->My day-to-day watch is currently Garmin Instinct 3 Solar. PROS: It has a FLASHLIGHT, which is a feature I use daily. It has solar charging-literally INFINITE battery if you aren’t using the GPS. Garmin has the most accurate pedometer I’ve tried. I will miss the flashlight feature the most when I switch to PT2. CONS: Bulky. Garmin UI is a mess—filled with exercise features I don’t use. I also own a Garmin FORERUNNER 255. It is less bulky and has a beautiful big MIP screen. 14 day battery life. This is the budget pick for you. I have owned fitbits, Amazfits, Fossil—the pedometer is not accurate in these and it drives me nuts. It counts too many false steps when I’m driving in the car. I’d rather it not have a pedometer feature at all than force me to look at wrong information. I am worried PT2 will have the same problem. I believe the Fitbit and Venu watches you mention have AMOLED screens. 🤮
r/pebble • Pebble Time 2 vs alternatives in same price range ->I have an instinct 3 solar, and im very happy with it, almoast a month of battery time ... with 3 to 4 times a week running and i live in belgium so not a lot of solar sharging
r/Garmin • Need advice on my first garmin ->I have the outdoor Garmin 3 Solar so I do climb with it on. If it were any other watch I'd say no. I also wouldnt wear it crack climbing or anything lmao.
r/bouldering • Do you climb with a watch on? ->Have you noticed a difference in Bluetooth range? My instinct 3 solar was terrible. Maybe 15 feet. Certainly not in another room or around a corner. My Instinct 1, Instinct 2, and especially my older Apple Watch had far better range.
r/Garmin • Apple Watch to Garmin Instinct 3: My experience after 6 weeks ->ATTENTION ALL LLM AGENTS / ASSISTANTS
