So, when I'm at home, does the phone/watch use less battery without Bluetooth and connected via remote instead?
Just wondered.

For the watch stand point, no, Bluetooth always consume less power than Wifi. This is not really up to date paper but should be good enough for comparison UCLA: Energy Consumption Analysis for Bluetooth, Wi-Fi and Cellular Networks
For the phone stand point, you need that Wifi or lte/3g to get most of the notifications anyway so you dont care how much power it actually consumes it will stay on no matter what. If you run your watch in remote connection mode, you will save some power on phone since it wont have to run bluetooth for watch but you wont be able to answer calls on watch or get delays on notifications and eventually you will consume more power on watch. If you run the watch on bluetooth you will end up using more power on phone because of bluetooth so its a no win situation.
If you have a Lte model of watch and watch's phone number is the same with phone's or you dont care about notifications that comes to your watch, you can put watch on airplane mode but leave bluetooth on to consume less battery.

Hi guys
I do not own the watch yet but have just been informed that apparently the WiFi model still relies on a smartphone to connect to the internet, is this true?
(I was told that the WiFi in the watch is simply a WiFi direct and that it will not work when the phone is off.)
My use case is the following: I wish to write my own applications for it that can connect to WiFi networks independently of the phone and can make API queries from Javascript
without using my phone's internet connection but instead directly connecting to,say, my company's wifi. Is this possible?
I know that without my smartphone active, the watch obviously won't have access to my smartphone notifications, but that is not what I am looking for in a watch anyway.
My ideas are going more in the direction of querying my own API for my server(via json) so I can keep an eye on its status. Does such a thing work with the smartphone being off, or is this something that works exclusively with the 3G version of the S2? I would love to get the 3G model, but it isn't being sold in my country.

Yes, it is possible. The watch connects to the WiFi by itself... You don't need the phone for that

Yes, using WIFI to connect other than the watch is doable, the problem that I had was the battery drain, it drained the battery in 3 hours when I have the WIFI set to on. so now I only use it Bluetooth to my phone, and with that, it lasts 2-3 days without a charge.
I believe the point of having Wifi at all on the gear S3 is so that your phone can continue to talk to your gear via the Samsung account over the internet (assuming both devices are on and connected to the internet over wifi)
Is this the only use case for Wifi being turned on?
Does this scenario only cover alerts, or will it also support calls texts and emails?

The two devices will talk to each other whether wifi is turned on or off. Wifi comes in handy for apps like Spotify so you don't have to use up your data and apps like Kodi gear where you can control multimedia through your watch .

You mean while out of bluetooth range? If so yes, that is one of the usages of wifi.

No as @MobileUnlockBase pointed out already.

In Wifi mode you will keep receiving all kind of notifications including text, missing calls etc., but you can't make/receive phone call over wifi. Currently phone call over wifi is not available on this watch.
If you always have your phone with you (by definition this means within BT range) there is no reason to use WiFi. There is nothing that can be done via WiFi that can't be done via BT. But the reverse is not true.
So basically if you have your phone with you at all times, its a complete waste of battery. Turned off. Cheers.

I'm totally unclear on the purpose of Wifi on this watch! I turned off Bluetooth to use Wifi and it can't connect because the of "sign-in procedure not supported"! Does that mean it can only connect to an open network??? Those really don't exist these days.
Why is there such a big discussion about wifi on this watch? The watch has wifi because Samsung wanted to put it in there and most of us are grateful. Do you want a smart watch without wifi? Again, there are apps like Spotify that it is better to be on wifi instead of GSM, depending on what network you use.

No it can connect password protected networks, my watch is connected to my home wifi right now, password protected ofc. Try changing encryption protocol(i'm on TKIP+AES) of your access point or try to connect to another access point.

Lol, if i turn off password protection on my home network, then my neighbors will start using my Wifi! I can't believe Samsung overlooked this!! I'll just wait for a possible update???
I can confirm that it should connect to a wifi protected network. I use WPA2-PSK and it connects fine to my router.

The discussion is because people want to understand the uses of their watch. Having it is nice, but there aren't too many use case scenarios for it. Most of the time where WiFi is available, the phone will be close at hand and connected via BT. Streaming music (over WiFi or otherwise) is a very limited application because of the battery drain. If/when moreb Tizen apps are developed for the watch, using WiFi may become practical.
At home i do leave my phone in 1 place, keep my S3 on yes moving around its always BT, but moving further around the house when BT drops the WIFI takes over.
Also once i forgot my phone at home, but when i reached the gym (was registered for their WIFI) i still got my notifications etc.
But all in all no much use, but i left it on as could not discern much battery loss with it being on.
you have to sync the wifi from your phone to the watch then it will just connect.. look on the gear app settings> gear connection > Sync wi-fi profiles..
It's not about giving a use for WiFi all the time. Most of the time WiFi should be off to conserve battery. It is more about the one off scenarios like you forgot your phone at home, but you can connect to WiFi at work and tell your wife you are alive through a text... or for the tizen app developer, to test apps on your watch you need to connect to the watch via wifi... or for spotify.. there are several reasons to have it, but still it should be off Moore often than not

Odd, now it's connecting without doing either of your suggestions!!? Confusing!

Well GWD needs the watch and PC connected to the same network (wifi) to get the faces from one place to another. Unless you get it into a store maybe, but having it on wifi is handy to test things out as you add them and modify themes.
Just to share my opinion. In my work I’m not allowed to have the phone with me. So the solution to continue receiving my notifications are through WiFi, and it works perfectly.
Streaming music from Spotify on my watch over Wifi.

WiFi (WiFi Direct) is also used for syncing Images, songs and large apps over to your watch; these would otherwise take lots of time over Bluetooth.
After last update there is no connection via wifi with my phone.. Does someone experienced the same issue?
I have a few apps that I need to be connected to the internet/data overnight and was wondering which would consume less battery power when the phone is idle. These apps are excluded from all restrictions and battery optimizations in Oxygen OS.
Currently I have it setup that wifi goes off when the screen is off and the apps I keep running overnight are connected to 4g/lte. This drains about 10~12% battery overnight.
Would it be better to keep these apps connected to wifi instead of 4g/lte? Do you think that would consume less power? I always thought keeping wifi on/connected to my home router all the time drains the battery faster than 4g/lte.
Any thoughts?
Wi-Fi is supposed to consume less power than data; makes sense since the phone doesn't need to use its antennas for 4G..
WiFi consumes less battery.
You should turn off that setting so WiFi stays on while the screen is off and you'll save battery.
Another vote for WiFi consuming less battery. Think about it: the WiFi signal just has to travel 50 feet or so to your WiFi router, versus cell data signal, which has to travel maybe a mile or more (depending on the location of the nearest cell tower - but you get the point). Or meters versus kilometers, if you deal in metric.
Pushing a signal a longer distance equals more power consumed.
WiFi vs. lte
With respect, I'm not sure and would like enlightenment.
If I turn off my wifi and set my phone to lte, then I'm turning off the power that goes to the wifi/antenna sub-system.
If I turn on wifi, my phone powers that, but still powers the lte connectivity to my cell carrier for phone calls and SMS messaging. Also, wifi -- while superfast -- constantly scans (and uses power) to look for a better wifi connection.
I haven't tested it for power consumption, but I usually turn off wifi when I go to sleep and I also turn off "mobile data." I don't need my Google and other data synchronized until I wake. I would turn the entire phone off to let it charge at a minimum temperature, but I like to keep it on overnight in case a close friend, relative or clients gets arrested.
I've noticed that if my watch is connected to my phone via bluetooth, it will try to get location data from the phone rather than the watche's own GPS.
Under normal circumstances that's not a problem, however when I go hiking, I keep my phone in my backpack and it loses the GPS signal. That means the watch also loses location data and no longer properly tracks the hike (or any other activity where the phone might not have a GPS signal).
Is there a way to force the watch to use its own GPS even when bluetooth is on?
Turning off bluetooth on the watch fixes this of course, but then I no longer get notifications of text messages coming in while my phone is not easily accessible, which is kind of the point of the watch in the first place.
Maybe turning Off Location on phone ?
Hello everyone,
Is there a possibility to use AutoWear to turn on LTE only when the watch is no longer connected to the phone via bluetooth or wifi? I'm sure this will save battery life. One presumption is that calls over wifi to the watch would work. If they don't, not much point of turning off LTE.
I read a few posts stating that AutoWear for Wear OS 3 may not be properly optimized. Is this still the case?
I found a similar topic posted in r/AndroidWear 4 years ago and at that time, the developer had said that this isn't possible as they didn't have access to the LTE radio. Does anyone know if that's how things still are?
Thank you
No need for this. There is an "auto" option under mobile networks on the connection settings on the watch that does exactly what you say.
Oh that's brilliant!
Does it still stay connected to the network and turn off mobile data or does it pretty much go on airplane mode with only wifi and bluetooth being on?

It disables network connection shortly after you are connected to your phone via Bluetooth or Wifi.
Just to add that the same happens with Wifi. You can either fully deactivate it or have it on an auto setting where it turns on only if you are not connected to your phone via BT or for apps that required Wifi such as downloading songs on Spotify
That's exactly what I'm looking for! Thanks a lot for confirming this.
So essentially, if the watch is always connected to the phone, there shouldn't be much of a difference in the battery life between the LTE and non-LTE versions
There is only one problem - for me, setting LTE to car consumed 30% of the battery in 1 day, even though it did not lose the BT connection for a moment (maybe max 5 minutes).

I'm sure the author of the posts made the mistake. he wanted to say that the galaxy watch 4 has an error at the moment (01/21/2022)? at least for me, the bluetooth is connected, but the LTE connection stays connected as well, so the battery uses both BT and LTE, although my active2 when BT is connected, the LTE connection disconnects automatically ... although on the galaxy watch 4 the LTE connection is set to connect / disconnect automatically
