Do not Like

  • SpO2 knowledge is difficult to interpret
  • Nonetheless requires every day cost with sleep monitoring and at all times on show

The Apple Watch Sequence 6 feels prefer it has perfected lots of the options I preferred about its predecessor. It has a brighter always-on show, a extra highly effective processor, quicker charging and two new colourful choices to select from. However the function I used to be most excited to check out was its new sensor that measures oxygen saturation within the blood (aka SpO2) with the faucet of a display. As somebody who panic-bought a pulse oximeter initially of the coronavirus pandemic and nonetheless checks her ranges on the first signal of a cough, the considered having one strapped to my wrist always was sufficient to pique my curiosity.

However in contrast to the ECG function on the Apple Watch, which has been tried, examined and cleared by the US Meals and Drug Administration, together with the irregular coronary heart rhythm notifications, SpO2 on the Apple Watch nonetheless appears to be in its early levels. Navigating all this new knowledge could be daunting for anybody who’s not a medical skilled. 

SpO2 leaves some unanswered questions

I purchased an FDA-cleared pulse oximeter, the machine medical doctors use to measure SpO2 in your fingertip, as a precaution when coronavirus instances within the US began to climb. Having low blood oxygen ranges does not assure you might have COVID-19, however it’s one of many main signs of the illness. I had learn horror tales of people that waited too lengthy to go to the hospital and had died of their sleep as a result of they did not understand their ranges had dipped in a single day. You must at all times examine with a doctor if you’re experiencing shortness of breath (one other symptom of COVID-19), even when a pulse oximeter says you are in a wholesome vary, however I discovered consolation in figuring out that I may at the very least use it as a reference if I ever skilled shortness of breath. 

That is not one thing you are able to do with the Apple Watch — Apple says it needs to be used for wellness functions solely and never as a medical machine, that means you may must take the outcomes with a grain of salt and should not use it to display for any kind of illness, which is what I had been hoping to get out of it. However there could also be different benefits of getting it strapped in your wrist always. 

Very like a pulse oximeter, the Sequence 6 makes use of crimson and infrared mild from its new sensor to find out the proportion of oxygen within the blood. However as a substitute of shining the sunshine via your fingertip, it makes use of the sunshine that is mirrored again from the blood vessels in your wrist to find out your oxygen ranges primarily based on the colour of your blood.

Apple’s new Watch Sequence 6 with SpO2 monitoring and cheaper…


Through the setup course of you are requested whether or not or not you need to activate SpO2 monitoring, which I did, however you’ll be able to at all times return and disable it within the settings after the actual fact. The very first thing I did after strapping on the Watch was open the Blood Oxygen app. It offers you a number of tips about easy methods to get the most effective consequence and you want to relaxation your arm on a desk or flat floor whereas the Watch is taking a studying. Then the 15-second countdown begins and also you’re accomplished — easy and painless. I acquired a 95% on my first learn, which was decrease than what I am used to from my pulse oximeter. Something above 90% is mostly thought of by clinicians to be inside a wholesome vary, however most often, increased is best.

I examined it a number of extra instances and acquired barely totally different outcomes inside a number of proportion factors relying on whether or not I used to be fully nonetheless and silent in the course of the check, the place I had the watch positioned on my wrist and the way tight the strap was. There are a lot of components that may have an effect on a studying, resembling pores and skin temperature or the place of the sensors on the physique. Aspect-by-side with my pulse oximeter, the Apple Watch was usually off by about one or two factors, however generally spot on.  

Measuring blood oxygen ranges over time

What was extra fascinating to me was the SpO2 knowledge that collected over time within the Well being app. That is one thing my pulse oximeter cannot do. In contrast to the Galaxy Watch 3, which solely does spot checks, the Apple Watch additionally takes background measurements all through the day (and night time). Click on on the Respiratory possibility on the dashboard and you will see all of your measurements plotted on a graph which you’ll be able to view a day, week or month at a time and filter by time of day or proportion. But it surely’s as much as you, or ideally your doctor, to interpret this knowledge.

I have been sporting the Apple Look ahead to six days and I usually fluctuate between 95% and 100%. My stage is normally on the decrease finish of that vary in the course of the night time as your respiration fee is lowered considerably. However there have been two nights or early mornings the place my ranges dropped to 92%, which scared me a bit. I used to be under what the Mayo Clinic considers a “wholesome vary,” however above what’s thought of a “low vary.” Ought to I be involved? Dips in oxygen saturation can sign something from sleep associated circumstances like sleep apnea to bronchial asthma, and even respiratory viruses like COVID-19, however I do not know precisely how low and the way usually it has to occur for it to be an issue, and the Apple Watch cannot reply that. I want the watch may let me know if one thing was off, the way in which it does with the low, excessive or irregular coronary heart rhythm alerts so I may lastly put my little pulse oximeter to relaxation. Perhaps sooner or later, and with sufficient knowledge and medical research, it’s going to.

Apple at present has three totally different SpO2-related research underway, together with one associated to bronchial asthma and one other for detecting early indicators of respiratory sicknesses resembling COVID-19.

With the Sequence 5 discontinued, the Sequence 6 can also be the one watch you may get from Apple with the electrocardiogram function, which Apple calls ECG, that debuted on the Sequence four in 2018.

New colours, brighter display

Other than the sensors on the again, the Apple Watch Sequence 6 may go for a Sequence 5. They’ve the identical physique and related always-on show. It wasn’t till I put them facet by facet that I observed a distinction. Whereas the display on the Sequence 5 dims when not in use, the Sequence 6 nearly appears to be like prefer it’s nonetheless on, which is very useful while you’re open air. Apple says it is 2.5 instances brighter and it exhibits.  

It is also the primary Apple Watch so as to add to the standard silver, area grey and gold finishes. Mine got here in a Product Purple aluminum body. That aluminum model additionally is available in blue, whereas the stainless-steel will get a brand new gold end. 

I just like the crimson, however I believe I would nonetheless keep on with a extra impartial tone for the body and spice it up with a watch band as a substitute. 

Claspless bands and Memoji watch faces 

Apple additionally introduced a brand new kind of silicone band with no clasps or buckles referred to as the Solo Loop

It appears to be like and feels just like the silicone sports activities band, however with no overlapping components. I arrange my watch with a black dimension four strap that Apple offered and simply slipped in on my wrist like a hair tie. The fabric feels stretchy and barely easy to the contact. I believed it felt a bit tight at first, however I barely felt it on my wrist after a number of hours. It is very important get your dimension proper although, as a result of the scale down for me would’ve been means too small. 

It will require you to measure your wrist before you purchase it. And for this you may want a measuring tape, which I personally do not at all times have readily available. It is also costly for a band that I would fear would stretch a bit over time. It is $49 by itself, the identical value because the silicone sports activities bands.

I am going to must report again on the stretching as soon as I’ve used it for some time. I do assume it might be an excellent various for teenagers, which Apple is now focusing on with its new Household Setup, as a result of it is much less cumbersome to placed on and take off.  

The brand new Household Setup function means that you can arrange a second Apple Watch that does not want its personal iPhone. You possibly can program location alerts from the mum or dad’s iPhone, designate which contacts they will talk with and restrict use throughout sure hours with the Faculty Time mode.

There are additionally new methods to customise the watch face with a brand new Animoji and Memoji that you could create immediately on the watch, which I did. I do not understand how lengthy I am going to preserve it on as my most important display, however I can see this being in style with youngsters too. 

Quicker processor, however solely barely higher battery 

The opposite key improve to the Apple Watch Sequence 6 is the quicker processor: Apple’s S6 chip relies on the A13 Bionic chip discovered within the iPhone 11 and 11 Professional. The Watch feels snappy loading apps, displaying messages and displaying stats in actual time. However the Sequence 5 already felt quick, and to this point I have never observed an enormous change in my day-to-day use. The Sequence 6 can also be the one Apple Watch to incorporate Apple’s new U1 chip for ultrawideband assist, which improves spatial consciousness between gadgets. The advantages of this new U1 chip is probably not apparent immediately, however ultimately will allow options resembling CarKey, which lets you use your machine as a key fob.

I additionally have not observed a lot of a change in battery life in comparison with the Sequence 5, which is disappointing — now the Apple Watch can observe your sleep, you may need to use it 24/7. The silver lining is that it is now higher at managing battery life throughout sure exercises and it exceeded Apple’s 18-hour declare in my testing. 


Vanessa Hand Orellana/CNET

The Sequence 6 can last as long as seven hours on a single cost throughout an outside run, up from six hours on the Sequence 5. Although I’ve not examined this out for myself but, I did discover that the Sequence 6 had extra battery left after a 30-minute out of doors jog in comparison with my Sequence 5.

Even on the times I took it for a GPS-only run with out my cellphone in tow, I nonetheless ended the day with the 30% cost wanted to trace my sleep. I may even squeeze in a pair additional hours within the early morning. It’s also possible to disable the always-on show if you’d like much more battery, which isn’t an possibility on any of the opposite fashions. 

The Apple Watch Sequence 6 and Apple Watch SE will cost to 100% in 90 minutes in comparison with the two-hour cost time of their predecessors, which helps velocity your day alongside. However generally my morning routine wasn’t lengthy sufficient for it to cost again as much as 100% and I ended up having to cost it in bursts all through the day, which might be laborious if you did not have a charger readily available. And also you higher hope you might have a wall charger at residence, as a result of Apple is not together with them within the field anymore. You simply get the cable with the magnetic puck.

Bye, bye Pressure Contact on WatchOS 7 

The replace to WatchOS 7 eradicated Pressure Contact on the Apple Watch throughout the board, so as a substitute of making use of extra stress on the watch face, you now must long-press to immediate an motion. You continue to get the identical haptic suggestions that you’d with Pressure Contact, however it did not appear fairly as satisfying. It additionally means you need to relearn sure actions like switching from grid view to listing view to your app display. In case you lengthy press on the app web page, all of them begin to jiggle like on the iPhone to rearrange or delete. The listing view possibility has moved to the Settings. 

Actual-time elevation and cardio health alerts 

The complete Apple Watch line may also get new health options with WatchOS 7, together with dance monitoring and core coaching, however solely the Sequence 6 and Apple Watch SE embrace a brand new always-on altimeter that gives real-time elevation monitoring you need to use throughout an outside exercise. 

The Apple Watch additionally makes use of the Vo2 max studying (most oxygen consumption throughout train) to watch cardio health ranges. It’s going to ultimately let when your ranges are too low with a brand new notification function that is launching later this 12 months. Based on Apple, this metric could be an essential indicator of general well being.

Nonetheless the most effective smartwatch, however with extra competitors 

The jury’s nonetheless out on whether or not blood oxygen monitoring turns into a must have function, however with the Sequence 5 discontinued, it is now your solely possibility if you’d like that always-on show and ECG app. These are large promoting factors for the Sequence 6 and I personally would have a tough time going again to a display I needed to increase to wake. The query now’s whether or not that is going to be sufficient to sway folks to spend the additional $130 once they now have a compelling various within the Apple Watch SE, which shares lots of the similar options for much less.
