Apple Watch Series 10 In-Depth Review: Worth the Upgrade?

[@The.JZA.]

The training load feature is a nice addition. Now they need to break it down to aerobic and anaerobic training so I can see if I am lacking training in a certain area.

[@richjacques]

Best feature of Apple watch that wasn't mentioned is Apple Pay. You might not call this a sports feature, but I think being able to buy coffee and cake on the sunday club ride without having to get my phone out counts as 'sport'... or being able to buy a bike for that matter.

I am still undecided. That watch would be great for sleep tracking but having to charge it everyday is a hassle. The Ultra has 2-3 days battery but is just so chonky for me.

[@alexandre-guzu]

Honestly you get used to it. Throw the watch on the charger when you take a shower or don't need the watch for a moment. Personally I think I'll get a Series 10 coming from a SE1 because of the fast charging stuff.

It's crazy that they are on version 10 and they are like "yeah...our customers should worry about charging this devise every single day....no need to solve that issue". And NO, the ultra 2 day battery isn't much of an improvement.

[@MrBecksy2]

Still not enough to make me give up my Fenix 6, and neither is the Fenix 8 (Garmin have blown it with the price there I think). Stick with the 6 for another year or so.

[@srhello08]

The most important question that no reviewer has addressed 🙃

@@Dcrainmakerso the jet black is more resistant than the iPhone 7 one?😍

[@squngy0]

Scratches at level 6, deeper grooves at level 7

[@AntonandSinan]

Excellent question, considering how badly iPhone 7 held up in that colour/finish! For this specific reason I ordered the rose gold one instead. I am coming from the original Apple Sport that is on its tenth year (yah I know😂, but it works 🤷🏻‍♂️) and that one is in gold which held up very well for almost a decade. So I think their matte aluminium finishes hold up better than the polished ones.

Series 10 is my first iWatch and it isn’t charging as fast as they claim. It takes an hour to charge up to 80%. Tell me about yours. I’m worried if mine has a defect or not.

[@kaylacrouse7094]

Yeah that’s not normal. I’m editing to ask if you’re using an older charger or cord? I would buy brand new. Could be the root cause of your slow charging. Especially if the battery lasts a decent amount of time

Great comparison again Ray! Still doubting about the bigger screen with my 17cm wrists😅 What is your wrist size for comparison?

[@bartsplaylists]

Take the 42 mm if you also wish to wear it at work or restaurants, unless you wish a tv on the wrist

[@lbgstzockt8493]

As a small wristed man (about 165mm) I recommend the smaller one. Aside from being large enough it also looks less ridiculous it is also cheaper and you get the exact same battery life.

[@AthrunZalax09a]

Love the in depth reviews you give. Thank you for keeping the quality of your analysis high, and airing what you would like to see them add - it's great insight for those of us who don't get to use all the different platforms. It really gives me insight into what is great across every platform. (And hopefully incentives Apple to improve!!) Apple and Google are clearly coming after Garmin for fitness. While most of my running and cycling friends use Garmin right now, if battery life keeps improving and they keep adding features, it's going to be hard to keep people from leaving their given ecosystem (Apple, Google, Samsung)

Hi. Is it worth it upgrading to s10 from se2?

[@uzaiyaro]

I've found it only gets to 80% after 40 minutes, which is still good, but I wonder if it'll go faster once the watch battery beds in a little bit. I have a power meter and it fluctuates between 1.5 and 5 watts, mostly the former. But with how long the battery lasts (I got 32 hours in testing with no power saving features enabled), I'm not complaining much at all. It's my first Apple Watch and I love it.

Is it possible to use double tap feature while running to switch between Maps and Fitness App so you can quickly see, in Smart Stack, your next turn/directions, and then let the Smart Stack go back to the Fitness app you had open? Meaning can double tap get a quick view of maps without having to touch your screen? This would be huge for me while running in new places but wanting to keep HR/Pace etc data visible.

[@roncronovich9095]

For many of the features disucssed in this video, it wasn't clear whether they were specific to the new Apple Watch 10 hardware and which are WatchOS 11 features that will be available to the Apple Watch models that came out last year, or earlier. For future videos, consider covering hardware-specific changes first, then new WatchOS features that work on earlier models, too. Thanks for considering my suggestion.

[@peros550]

[@lbgstzockt8493]

The subscription cost of the Whoop is a total dealbreaker for me. I can live with the shorter battery life because I don't do ultramarathons and can deal with charging once a day. I would either keep the series 7 or upgrade if you feel like the upgrade are worth the cash.

[@jayjimenez6524]

Thanks for the review. Have a Garmin and moved to Ultra… do you think this regular apple watch can last through longer workouts or a marathon through the evening (w/o charging). Even the Ultra gets drained after longer sessions.

Garmin is known for workouts and having the best battery. You will notice the huge difference.

[@michaelgilreyes]

I wonder how the battery performed given all the activities you have done

[@Gurenn83]

Sometimes I feel like Apple can make it last more than a day but they are holding back so that we get to buy every year or two. Reminds me when Tim Cook got asked a question and said "Buy your mom an iphone."

[@notyouraveragevegan2677]

That’s all I want to know too

[@Dcrainmaker]

I covered that bit a bit more in my written review. In this case, there's two pieces. First is the GPS piece. In that case, things were on-point and as expected, I was on target for about 8hrs of GPS run-time (by evaluating before/after battery percentages on 1hr+ long GPS activities). Their current spec for this watch is 7hrs GPS time, so above that. Meanwhile, for daily smartwatch time, I'm getting lower than expected estimates, which, doesn't really make any sense to either myself or Apple (nor does it match what some of my friends testing are getting, which is well beyond my specs). Apple's best guess is something is downloading/cachihng/etc in the background that's burning more battery than it should . They're digging into it at the moment, and I'll update more here (and my written review), once it's sorted out.

[@thisisbenji90]

@@Dcrainmaker I wonder how many Apple Watch users are actually even regularly doing activities that would be longer than 7hrs GPS time? The main issue I have with my Apple Watch for long-rides isn't the battery, it's the fact that navigation just feels so half baked compared to my Wahoo and if I'm doing a ride that long, I DEFINITELY need proper navigation.

[@notyouraveragevegan2677]

@@Dcrainmakerthank you! What I’ve been wanting to see is gps+ media in real life use because I can’t be the only one that wants to train with music/podcasts. I switched from a Garmin and been a 10 year long Garmin user) to an Apple Watch series 9 this year in the hopes I could leave my phone behind for once while marathon training, first and foremost for safety as a solo female runner but also for media.. I’m finding that the battery will tap out in as little as 2.5 hours if I’m streaming music (maybe changing things a few times) with the gps running on long runs. Also, I find if I don’t start with close to 100% I could also end up in trouble. Just this week I was out for 8 miles (about 50 minute run) and I got a low battery warning after starting with 50% and running gps + music streaming (service was bad and it had do search for a bit in different spots). So real everyday use for actual training is what I’d be really interested to see when looking at battery. I know I should really be using an ultra but I’m only 5’3 and even being used to wearing bigger Garmins the Ultra is just so big on me. I was disappointed they did not give us a slimmed down version in this announcement.

[@radi0aktivetoy]

I just wish the battery would improve even a little bit model to model. I'm upgrading from my Series 7 *only" because the already poor battery is completely cooked after 2+ years of all day and night use. I know the battery isn't improved but a full capacity has to be better than the 80% on my current watch. I can't justify the cost of the Ultra so I'm going for the aluminum with a trade in, begrudgingly.
