So I am keen to read opinions about the relatively high SAR value of the Alcatel Idol 3 and its possible negative
effect on the human head and body. I remember owning phones having significantly lower SAR values, such as the
Galaxy Nexus and the Galaxy Note II, clocking in around 0.2 W/Kg, instead of the idol 3's 1.42 W/Kg.
Should we be worried with every day use? The maximum allowed SAR value is set at 1.6 W/Kg. Below is the official report
of the Idol 3 regarding SAR ratings:
THIS MOBILE PHONE MEETS THE GOVERNMENT’S REQUIREMENTS FOR
EXPOSURE TO RADIO WAVES.
Your mobile phone is a radio transmitter and receiver. It is designed and manufactured
not to exceed the emission limits for exposure to radio-frequency (RF) energy. These
limits are part of comprehensive guidelines and establish permitted levels of RF
energy for the general population. The guidelines are based on standards that were
developed by independent scientific organizations through periodic and thorough
evaluation of scientific studies. These guidelines include a substantial safety margin
designed to ensure the safety of all persons, regardless of age and health.
The exposure standard for mobile phones employs a unit of measurement known
as the Specific Absorption Rate, or SAR. The SAR limit set by public authorities such
as the Federal Communications Commission of the US Government (FCC), or by
Industry Canada, is 1.6 W/kg averaged over 1 gram of body tissue. Tests for SAR are
conducted using standard operating positions with the mobile phone transmitting at
its highest certified power level in all tested frequency bands.
9 10
Although the SAR is determined at the highest certified power level, the actual SAR
level of the mobile phone while operating can be well below the maximum value. This
is because the mobile phone is designed to operate at multiple power levels so as to
use only the power required to reach the network. In general, the closer you are to
a wireless base station antenna, the lower the power output of the mobile phone.
Before a mobile phone model is available for sale to the public, compliance with
national regulations and standards must be shown.
The highest SAR value for this model mobile phone when tested is 1.39W/Kg for use
at the ear and 1.42W/Kg for use close to the body.

SAR is a really useless measure.

"even the FCC now casts doubt on the usefulness of comparing maximum SAR values for determining the potential health risks of cell phones."

So it's basically about locations where there is bad reception and the cellphone trying hard to get a connection, increasing the SAR value. It's still
relatively high, the peaks. Anyone else input?
Peaks don't mean anything by themselves, its the average power put out over a long period of time that matters. Think marathon runner vs sprinter.

I guess you're right. However, many people advise to wear/carry a cellphone (our Idol 3 in this case) away from the body. How does that even work for men? I've always carried my cellphone in my pocket. How dangerous are we talking??

Put it this way, you are FAR more likely to be killed by reading a facebook post on your phone rather than paying attention to traffic than you are by the minimal radiation put out by the phone in your pocket.

I guess you're right, but I don't like tumors etc There's always a risk of course, just wondering how large that risk truly is...
nobody likes tumors and cancer and so on...but the thing is, that you more likely got cancer from stress and ubhealthy living style than from mobile device radiation (my opinion). But anyway if you want to avoid SAR radiation to your body buy a device with lowes SAR HERE Is link to one article in Czech (because iam from Czech republic) and if you use google translation you will notice, that lowest radiations has for example LG G3, so go for this device and you will be happy (more likely untill you got tumor from something else than SAR radiation ). I myself dont take this things so seriously because there are no proper research and no straight proven consequences between tumors, cancer and magnetic field radiation. It simply stands on more things than a device you use (genetic predisposition, living style, stress...). Thatswhy i put the post above
edit: just for the end..there was a research that prooves that when you ejaculate often (at least once a day), that lowers significantly the chance to get prostatic cancer. so turn of the computer and go for it.

Although your post made me chuckle a couple of times I do feel it could be a serious matter, as I think we all would prefer a SAR value as low as possible. I reckon we can safely use our i3's however.

I would prefer to see a better way of rating a phone's total RF power output over a period of time. For all we know, the Idol 3 may be much safer than a Galaxy S6 over a typical day even if it does have a higher SAR peak. The likelihood is that both are amongst the least of your worries in life.

No, I haven't used it. But as a graduate electronics engineer I know a thing or two about electrons and radiation. And what their website says:
Overlay Plus Power Extender is made of a newly developed speical material, PAT.P. This material generates cavity radiation energy and dissolves slougs stored in the battery. This improves the flow of ions and hence will be able to improve battery power significantly.

This is pure nonsense. The law of conservarion of energy dictates that enegry cannot be "generated". It can be transformed and stored, and that's what a a battery does. If there was something that really could generate energy, it'd be a perpetuum mobile, and whoever would have invented it would become the richest and most famous person in the universe, and certainly would not have to sell Mobile Phone Power Extenders...
Another argument, from another point of view: Mobile Phones are a competitive business. Manufacturers try almost everything to improve their phones over the ones of the competition. If that power extender really worked, don't you think some big manufacturer would have bought and used it in all their phones by now? After all, a 30% increase in battery life is a very nice selling point!

I think it claims to make the battery more efficient, but the explanation how makes no sense to me either.
Buy a spare battery and get 100% extra battery life. Guaranteed.
I'm thinking of buying the Martin Field Overlay plus Power Extender.
I've read lots of review of it and it does make a difference, 2% ~20% depending on the product tested on.
To date, no one has tested it on the XDAII.
If someone has, I wanna know the results.
Gullable Consumers
:lol: :lol: :lol: :lol: :lol: :lol:
Don't any of you remember the little 'sticker' you were supposed to put on the back of your cell phone to 'enhance your coverage area'? Ever heard of 'snake oil'? This product takes advantage of people who buy into hype. It's quite impossible to put a sticker on the back of a phone and make the battery last longer. Trust me on that. But, if you're into such out of this world miracle cures, here's one for you to buy...

Maybe it'll make your XDA or XDA II get better coverage. I wonder what would happen if you used two of them?? :wink:

Well to me this product is a good reason NOT to buy ANY Martin Field products.... I am a little unforgiving in regards to things like this though
You have to be really sleazy to market crap like this. Scumbags.
BTW, the stick-on antennas often actually DECREASED signal in many tests. So I guess you can't say they "don't do anything..." :roll:

This device, as attractive as it may be, is starting to rack up some real negatives:
1) the confused (for consumers) situation with the Qualcomm chip and the US Court injunction (what effect may that have on overall sales and consequently warranty, quality control etc ?)
2) variations in build quality (sliders, screens unglued etc)
3) constant WWE ROM supply problems and high prices
4) the ongoing argument over video drivers (may not be a real issue, since it seems unlikely to me that any class action will actually occur)
I'm getting a small amount of "sand in my shoes"
I wonder: why are we bashing this device more and more lately? The more we bash, the less people buy, the worse TC sales are, the less support we'll get and eventually we might wind up with NO software updates at all..
So let's try to think about the positive things shall we

1: is a non-issue, by the time in 2009 when HTC will need to use a new chip, this device will have been replaced in all likelihood, or will have a slightly different chipset. No problem.
2: I've not heard of any problems, slight noise from a screen and concerns here and there, but no issues with previous build so why this one? Anyway, you get a defective one, you return it!
3: supply will level in a month or two, place an order now and you should have it early Feb. The fact that it's popular should tell you a lot.
4: again is a non-issue - either you want a multi-purpose phone like this or you don't. The video will be as released, I don't believe anything more will happen with it. It's fine as released for general purpose stuff...
Essentially, if you wanted a high-performance video device this one was never for you; if you want a great PDA phone it is. Make your choice. For me build quality is excellent and the rest is of no importance.
If you want great video performance buy a Cowon iAudio A3 (I got the A2), great rendering to high resolutions too in widescreen format, bigger and heavier than the TC but good for all your video/audio/FM radio/pictures/document needs. No input possible of course. That's why I needed the TC

Post cognitive dissonance:
http://www.ciadvertising.org/sa/fall_03/adv382J/mbabbott/advertising.htm
There have been high expectations from the device for a long time, combine that with the difficulty in actually getting hold of one and a couple of new models from other manufacturers on the horizon, and those expectations will change. Cognitive Dissonance is a much more difficult problem for companies to manage these days, mostly because of the internet.
I must say, truly interesting! And indeed I've caught myself luring to Eten and LG devices, but none are up to the TC challenge imho.
All i can say is i am right with rickgillyon.
Everyday, i am happy to have TC.
GPS, sound, screen, weight, radio, phone are perfect.
A lot of Applications are available.
I haven't buy this device for video but if it works well, i will use it some times.

True enough, although I have not yet made a decision to dissonate about. I had been somewhat interested in the ETEN X800 until some independent tests showed a slowness in its response - some people report it is now improved with some ROM changes, others don't think so.
My decisions tend to be based on the actual experience of the product - paper specifications simply weed out those that do not interest me to start with.
It's also interesting that the optimists here discount issues - eg. one reply to my "sand in my shoes" post suggested that by 2009 the Qualcomm Court injunction will be irrelevant as HTC will be using a different chip. But I don't really intend to change devices annually, so for me it is a potential issue, particularly as the outcomes cannot be easily predicted.
Supply is an issue - we've been given way too many false dates since August to believe "the next one". And there has been no real attempt at an explanation - but given the seemingly unglued screens and flimsy controls reported on some units, quality control on production issues may be a factor. Simply returning it is a very last resort, especially from O/S. It's far better to avoid the problems to begin with.
But then, without the optimists life would be dull I suppose. Even when they quote posts selectively ...

The outcome is already known, replacement chips are ready according to Qualcomm, and you won't have to change your device - they won't make us hand our phones back in...
As I say, it's a non-issue for the end user.

I've discussed this out in another thread - so repetition is pointless. If you believe Qualcomm's rationalisations (after they have been convicted of knowing patent infringement), then I have some shares in the Sydney Harbour Bridge for you. Cheap, too. Such chips need to be fabricated, then assembled in new devices for testing. Qualcomm's "new" chips are also subject to a further Court examination next February before design release- the time and results of that are not predictable.
I'm not suggesting that the devices already sold will be recalled - do you understand the term "straw man" ? If world wide sales of the P3650 are repressed through this issue, HTC will reduce development and support for this model as fast as it can ... that's the core of my comments.
It's racking up real negatives. The only defence to this is cool examination of potential outcomes, or risk wasting money.
Chips need to be fabricated? Really? I'd never have guessed...
Fact is that Qualcomm, naughty as they undoubtedly are, have been working on this problem for some time as they knew they would lose. I see no reason to doubt that chips will be ready, and will be available. The reason Qulacomm will be hurrying out a replacement is to avoid the punitive commission they are paying right now.
HTC support? Surely you're kidding?
If, as you say, the issue stretches beyond early 2009, and supplies stop in early 2009, what's the difference? How often have you seen real support or development of an HTC product after the first few months? IME that support and development only comes in the cooked ROMs.
This still looks to me like the best device available right now, and with Qualcomm and HTC able to use the chip until 2009, not much of an issue for us. What's the alternative?
I am surprised at the amount of stick this device seems to be generating. I bought it as a replacement for my original Touch as I missed 3G and I have to say it's a fairly stunning device. Build quality on my unit is excellent, the slider and the scroll wheel are firm and responsive. The unit itself performs what I expect of it: PDA, email, fast internet. I fully expect this to be my longest lasting phone for quite a while, easily until end of FY 2009/2010. Problems like video drivers etc I don't really understand, it's adequate for a phone. If I want to watch videos I tend to use a full video capable device (eg PSP) rather than try to watch them on a phone.

No no, I do insist we bash them PERSONALLY, but not on the sales websites, as potential future customers may be scared in the future, even if the issue is already resolved, and therefore make the release of TC a fiasco, which would make HTC not distribute any sw updates...
Just a question:
How much would an external antenna help to get a better signal?
I would like to use the TC to track a short hike. Due to the test mentioned above, I would be forced to take the TC in my hand all the time. So I thougt I plug in an external antenna and fix the end somewhere to my clothes/backpack. Would that help?

Depends on the satellite coverage... My country has only 8 satellites covering it, so we couldn't utilize it fully even if we wanted to. (I don't know the background but thats the max number of lockons everyone gets around here)
But if your TC performs well in the city, i don't see any need for an external antenna, but an extra battery is a different story. And I hope you have other tracking softwares in your arsenal than the included TomTom...

With TomTom it would be a very short trip.
No, I plan to use TrackMe which was created by someone here in the community. It allows you to turn of the display, so the device consumes less power.
The problem is, that the TC didn't perform that good and I was thinking if it performs better with an external antenna. Especially in wooden areas I hope to gain a significant better signal.

You'd definitely get a better reception, but that would increase battery drainage. Bigger external antenna, heavier the drain on the battery.
But you can always pack the external antenna, and use it if needed. You won't loose anything, and we'd get some fieldtest results from the woods in Germany
@rickgyllion
Wot, no Harbour Bridge shares ? I'll even lower the price ! Oh well ...
"If, as you say, the issue stretches beyond early 2009 ..." I never said that, I simply pointed out that Qualcomm still faces unpredictable Court examination of its new designs. An inconvenient fact ...
"How often have you seen real support or development of an HTC product after the first few months?" Since the 1st non-English ROM devices have now been out a few months, one might think that stage has already been reached.
Between Qualcomm and HTC, it's a real stuff-up.
My attempt at resolution is that I have pre-ordered both the P3650 and an alternate non-HTC device. Both are due "in February" or "real soon now" or whichever comes first. When one or the other finally makes it to the retail market, then I'll make a decision.
Hi,
I was wondering if someone who has an O2 Orbit 2 would read the box it came in, and tell me what the following SAR ratings are.
HEAD SAR =
BODY SAR =
I know that there are some figures bouncing around the net, but they all seem to contradict each other, so that is why I was wondering if someone who actually owns one could quote me from the box or manual.
Thanks
SAR?
Hey Ppl!
The SAR rating which is printed in the German O2 Handbook is shown as 1,72W/kg. There ist no differncing between head and body rating. The same rating is shown on the O2 Internetsite.
Remember, if you have a bad cell the SAR rating rises to the max, in good cells the rating is much less than the max.
Frank
You see I had heard that figure !
...and it is the figure which is printed on the O2 UK website but I don't know whether this is just an outrageously high SAR rating, or whether it is misreporting, i.e. a 'combined' SAR rating
i.e.
HEAD SAR 0.888
BODY SAR 1.81
As is suggested for the Touch Cruise in this thread...
http://forum.xda-developers.com/showthread.php?t=371121
Does this phone actually have the same SAR as the Touch Cruise, its just that it is reported differently?
If this phone's SAR is 1.7, then that is ridiculous !!!!
The n95 for instance (I know, Nokia are evil, but for the sake of comparison...) has a rating of 0.58 !!!
I don't care even if it is the Max - 1.7 is far too high
I was literally on my way to buy this phone, when I found out the SAR rating !
As a result I am no longer going to buy it !!!!
Why should the HTC have SAR ratings which are so high ?????
SAR differences
Hey kdm!
Why u should by a HTC device? Because they`re cool and in the forum very good supported.
Everybody knows about SAR and I`m using an BT headset for every call.
The Hardware of Polaris and Orbit2 is the same, like u read your linked thread.
I like my Orbit with my headset!
Frank
er... wots SAR then?
Oh ok, Specific absorption rate right?
http://en.wikipedia.org/wiki/Specific_absorption_rate
Isnt google amazing!
has anybody really proved the SAR rating thing yet? last I heard here in australia was that EU phones are more powerful then AU phone and as such the rating system never came in to effect in australia. Well the way I look at it is I do much worse things then use my phone....
ANyone ?
No one still have their box or manual lying around ?
What does it matter dude?
I sure hope all this SAR stuff is crap, because I sleep with my phone next to my head every night!

Wow ! Thats living life on the edge !!! I think even those who state that mobile phones are largely safe still caution against that !
Look, to be honest I am undecided as yet whether SAR ratings really are something to worry about, but until it is established once and for all I think it better to hedge ones bets !
As a result I went for the Touch Cruise instead of the Orbit2 becaus the SAR is reportedly lower.
Radiation emmisions
Hey kdm!
Think about all the radiation of atombombs, nuklear accidents like tschernobyl and harrisburg and all the untold accidents... The radiation from outer space and so on...
About all the radar for airtraffic, Radiofrequencies and all the other emmisions we are exposed to everyday...
Without any longtime (50 years and longer) studies i think it would be difficult to assess the effect of all these including the SAR effect in our heads...
Just think about it...
Frank
Bundesamt für Strahlenschutz, (the Federal Office For Radiation Safety in Germany) rates it at 0,89 W/kg (http://www.bfs.de/elektro/hff/oekolabel.html)
Here's a link to a list of many phones and their SAR ratings as reported by Swisscom (http://www.swisscom-mobile.ch/scm/mce_sarwerte-en.aspx). Most Touch phones listed are between 0,4 and 0,8 W/kg.
There are two different standards for maximum exposure limits. The International (2.0W/kg) and the US FCC (1.6W/kg). The information above is based on 2.0W/kg testing. The SAR ratings listed throughout the internet for this phone range anywhere from 0,4xx to 1.4xx W/kg, which shows that testing and reporting varies as do beliefs on what's safe and not safe.
Best way to avoid cooking your brain is to just use the speaker phone or an ear piece, corded preferably. Using a bluetooth earpiece can be just as bad or worse (in the case of inside-the-ear dwelling models) than having the phone next to your head since they too put out RF signals.

Same hardware (HTC Polaris / P3650), really only cosmetically different.
This morning while searching ebay for reasonably priced solid gold toilets (or other things just as frivolous) I happened across a micro USB solar powered cell phone charger. It was priced at around $35, and while I had no real interest in buying something that probably doesn't work, it still made me wonder what if it did?
So lets assume my galaxy s3 is a 2100 MAh 3.8 volt battery, and it instantly charges to full when plugged in. This means it would consume roughly 8 watts every time you charge it from 0% to 100%. Lets not get overly technical and try to factor in the energy used by your charging cord.
Electricity in my state (New Jersey) costs roughly 21 cents per Kilo-Watt Hour (KWH). This basically means for every hour I use 1000 kilowats, I am charged another 21 cents on my electric bill.
This means if I charge my phone from empty to full exactly twice per day, I am roughly spending $1.23 per year to charge my phone. If the cost of electricity stays the same, it would take me 28 and a half years to break even on the cost of the solar charger.
how much would it cost you?
Since most of my charging is done at work.. cost me nothing.. Really though.. you are on to something... if only could mass market that and people would catch on then it would be great..
Well I think they'd have to really improve on solar energy technology before anything like this is realistic....I just saw the product as more of a novelty. Even if it does work its probably going to net you a couple percentage points an hour, nothing practical.
I just posted this on my facebook page and the response I got made me realize the smarter option would be to get solar panels for the house instead!
i think the purpose of a solar powered charger is for camping/hiking trips where electricity is not available and you can charge your ipod or phone

I'm sure it has many prudent real world applications, I was just a little bored and thought this would be something a little fun to keep the juices flowing.

i should mention that the concept is the same for hybrid cars. you pay a premium for them for gas savings that could take awhile to pay off (not including special maintainence, etc)
but maybe be part of something bigger... be green
You could use your car charger that uses your car battery/alternator to charge your phone if you are worried about using your home electricity! Just like one post said its more geared towards camping/hiking our any outdoor activity where electricity isn't present.
I gave a gift of a radio that takes alkaline batteries, but also has (replaceable) lithium batteries that can be charged via DC adaptor, built-in solar panel or hand crank. The solar panel allows for the radio to have battery power from the rechargeables without having to crank anything, especially if this radio is kept out during the day at a beach or campsite. It has a connector for charging devices such as mobile phones, which would essentially take much of the day for a low charge - but, that is most practical for when other sources of power are not going to be available for awhile.
While shopping for that radio, I came across solar chargers that are dedicated to supplying devices with power and are thin, flat products that often unfold and have greater surface area than a typical device with a (small) integrated solar panel. Some of these are expensive, but your ability to put a more substantial charge into a battery backup (for general use) or directly charging your phone without any sources of grid-based power is the primary purpose, I feel. A Brunton Explorer2 or similar is something I would go for in these cases and the issue is not comparing their economy to grid costs of the current day, but long-term ability to have off-grid or backup sources of charging power when you need it, I figure. Plus, incrementally going green isn't ever a bad idea: if I owned a solar charger, I'd keep my phone off the USB or wall charger most of the time.

I did some looking into this. It would take about 19 years for a Honda civic hybrid to pay for itself. Accounting for average miles driven across the US, maintenance of the car, and gas milage. I was bored

Don't think they're meant to pay for themselves, as they aren't alternative power sources - they are parallel hybrids meant to stretch the use of their gasoline engine.
Something like the Volt is a more serious version of that concept, being a serial hybrid whose wheels run almost exclusively off the electric motor.
Being "green" isn't always immediately the most economical choice in these relatively early days of people realizing it's beyond time to try and minimize the speed of global warming, etc. But, it's meant to be an incremental choice towards more responsible use of the dirty resources we know and love. IMHO.

No no no no no! You're all wrong!. All of my home electronics run off of electricity and theres no smog or global warming in my house!

You have to believe global warming exists in the first place. Just keep in mind there is as much evidence against it as there is for it.

No.
There is no scientific balance of evidence on global warming for/against its reality, and peer-reviewed studies have overwhelmingly shown its existence in a rather cold and analytical manner since at least the 70s.
Sure, businesses that seek to run away from taking responsibilities of their own pollution creation - from manufacturing or as outputs of the products they offer - do fund a number of pseudo-scientific PR studies to attempt offering the appearance of a scientific debate to purposefully keep the public wondering and debating, but no counter-evidence exists on the existence of global warming as a general phenomena in the scientific community. None.
Science is all about testing and retesting, then testing assumptions again - global warming is an easy reality to measure. Causes are still being studies, but the big ones are generally well known, and ways to mitigate are still being researched and even tried.
The business PR effort to offer an appearance of global warming debate in the scientific community utilizes easily debunked, pseudo-science at every turn - usually from privately funded studies, but sometimes they gain like-minded adherents who simply run with the misleading interpretations of highly particular data sets as part of gaining a subculture of defiance against . . . something. The man, government, smart science, whatever your cultural bugaboo might be. This is trap that people such as Michael Crichton have fallen into.
The anti-climate science PR push is equivalent to those many years of tobacco product manufacturing and distribution companies funding misinformation about the effects of cigarette smoke on human health, influencing USA lawmakers and a portion of the public to take sides against rather simple scientific facts . . . until that dangerous farce finally ran its course.
There is no scientific "debate" against the reality of global warming, and your preference for V8s (which I grew out of decades ago) has no impact on climate science - only your perception of such, perhaps.

I spent a couple minutes, because this is easy - mostly time looking up a bookmark.
Wasn't a specific point - it's the whole point about global warming. Which relates to one use of solar chargers that the OP offered, btw. That, and I have a tendency to not let nonsense get a free pass.
Your point?

I didn't mean to start any fighting...this was meant to be a lighthearted thread.
Just remember we're all here to support one another. All our rage should be directed at Verizon.

I just want to let you know that someone I never met on a phone forum isn't going to make me suddenly decide I am wrong.
I just said not everyone agrees with you, and obviously you are insecure enough in your views to have to feel the need to even try and start a debate over it.

Right, I'm calling out your anti-science view on a technology forum in a minor manner, which in a grass-is-blue and sky-is-green world makes me insecure, Mr. *hrr-hrr-hrr-I'm-hiding-behind-my-V8-vehicle-engine-purchases*. Lovely projection there, nosympathy - please try again, I'm all for private messages.
I'm not trying to convert you: you're simply wrong, dangerously so. I'd like others to see that your unsupported "opinion" (which is actually willful ignorance - for which you haven't offered a shred of evidence) - seems entirely counter to talking about actual science that can power or be otherwise useful in using our favorite pieces of techology . . . which were created, in essence, by people who studied one or more disciplines of science. Actual science, that is.

Interesting discussion. We can try to be civil to one another though...
That said, my 2 cents:
Recent data does support that global temperature is rising. The question that's hard to answer (and has been unproven to date) is whether this warming is man-made. Could man-made pollution be a factor? I think so. Is it THE factor? That's open for debate.
Hybrid cars: just food for thought - how are we getting rid of all those batteries?? I can't imagine those battery-acids are earth friendly.
....and no one is even discussing about the EMF generated by hybrid cars. EMF is ionizing radiation - ie. it has enough energy to break DNA (cancer risk, people!!). So if you driving a hydrid or a Volt/Leaf, you're sitting inside a pretty high EMF field. Personally, I can't take that chance with my little kids.
Solar panels. I think they're promising. Would love to get solar panels for my house. (1) too expensive. (2) efficiency sucks. Best panel is only about 20% efficient. Hopefully this will get better soon. Sunlight is free. Might as well figure out a way to use it!

I've seen multiple websites claim it will have it and some claim it won't.... so is there an official answer?
Be cool. I don't have diabetes but real time monitoring of your blood sugar level is fascinating and provides valuable information.
Haven't seen anything official yet, but have pre-ordered the Galaxy Watch 4...
Unless it's a hidden feature to be released later, no glucose monitoring. And I doubt the included sensors are capable.

Apparently not.
It doe have bioelectric impedance analysis (BIA).
How well that works I have my doubts but interesting. Being interested to see if it can detect hydration level changes.
O2 saturation is what I really like to see even if not high accuracy.
Samsung Galaxy Watch 4 review
The Samsung Galaxy Watch 4’s sharp design, smart software and standout health sensor make for a promising upgrade that somehow costs less than last year’s version.

If it could track hydration accurately, that could be a big deal for elderly who often have trouble recognizing they're dehydrated. But it would have to be accurate within <0.5%.
Supposedly SpO2 is much improved - I'm assuming since Sammie promised enhanced sleep tracking for the GW3 and never delivered. But the claim is you can set it to track SpO2 every 1 second while sleeping, or every minute (not sure how every 60 seconds would be useful, though).
Disappointed it doesn't have temperature readings. With HRV (which, for some reason, GW3 doesn't measure) I could ditch my Oura ring. And if they get sleep tracking right, or at least allow the SpO2 to be used by Sleep As Android, I'd be really happy.
The hydration level effects conductivity so it would show it but not as a calibrated absolute.
The reason for high time frame in sleep O2 measurement in sleep is sleep anapea detection.
Body temp reading be quit helpful, good point.
Doesn't have it. From what I've read the tech for this is still at least a couple of years away.
