I have ordered LTE version and now I read in some forums and Youtube that Bluetooth version is working fine in every aspect but the LTE version is getting heated too much, especially while calling
My question is does everyone have the same opinion ? It is getting heated only when LTE coverage is low ?
Does it get heated while calling using standalone LTE mode or heating is there even if stream using watch LTE ?
Is there any chance Samsung would fix it or it could be because of Exynos or other hardware issues?
No heating issues and have LTE always on. My signal has good 4G coverage...
Yes, overheating is an issue for me especially when signal is low. Low signal makes the gw4 overheat in about a minute. When calling with good coverage you should be able to talk at least 5 minutes before overheating. Standby on LTE is not an issue if not transferring lots of data.
I don't have any heating problem... until I switch to LTE.
When using the Bluetooth, the battery drain is minimal, and the watch stays cold.
When using LTE (no problem with the signal), the watch heats a lot, especially when it's trying to connect to the phone. Yes because We don't receive most notifications if the phone is not connected. Battery drain is also huge. Like 4 or 5 times the Bluetooth usage.
I wanted to send it back, but tbh, I don't leave my phone away that often. Except in the swimming pool or the shower, where heat is not an issue, I almost always have my phone at Bluetooth range.
So I kept it, that's a good watch, the biggest flaw is the battery life.
I have both 44mm and 46mm and both overheat un low signal areas while on a phone call
As others have said, if you have LOW signal, cover it up or whatever to create low signal it's gonna overheat and suck your battery dry. The GW3 LTE did the same thing.
I sleep with my arm UNDER my pillow. I've learned to turn off LTE at night or I'll enjoy a nice dead battery and missed sleep tracking in the morning.
I wonder if the Apple watch has these issues?

No. The calls I made were VoLTE. Still overheat. Small amounts of Data is OK like notifications. Just phone calls cause problems.

Do you own Classic varient or the normal varient? It is learned that only the GW4 over heat and there is no issue with classic varient.

I am still waiting for my pre-order of GW4 to arrive. GW4 is thinner than classic and if slimness is the reason for heat I thought I should cancel GW4 and reorder Classic version, that's why asked.
Just adding my experience. I have both a 46 Classic and a 44 Regular/Non-classic. Both overheat (in fact the Classic seems slightly more prone to it but only slightly).
Overheating occurs when LTE signal is low, and actively using the LTE connection (calls, updating/downloading an app, streaming music etc.). Just being on standby / remote connection to phone to display notifications seems relatively fine. Though the Non-Classic did shut down one time just receiving a text message.
I mostly have my phone with me, and LTE is just for emergency use, so I can live with it but it is beyond annoying. I would much rather they run modem at lower power / treat low signal as no signal than ramp up the power and cause phone to shut down.
My watch 4 44 LTE overheaths too when LTE signal is too low.

Hi
I tried searching Google, but get a lot of different answers.
I live in an area with a very bad cellular coverage. I always have 1 out of 5 bars and when I turn mobile data on, it is mainly LTE, but jumps a bit between LTE and Edge and rarely H and H+.
Can that cause a lot of battery drain? As I just factory reset my phone to get rid of every change I did. I enabled Stamina Mode, surfed the web for 15 minutes and my phone was at 95%. Is that normal? Because if my math is right, that shouldn't give me more than 5 hours of screen time, while I heard people getting 8+ without Stamina Mode.
Am I missing something or is their some very needed settings to be changed? Sync off, GPS off, bluetooth, Brightness is as low as possible, NFC off, black background (less power consumption), Wifi off and Wifi constant searching off.
U can easly check urself how cell signal draining battery ,first Check how it is with normal H+/LTE then charg it again for 100% and use ur smartphone with plane mode acivated ,now subtract result from 2 "experiment"
Also of note is that black backgrounds mean diddly on our displays. We aren't on OLEDs.
Also, if you ARE in wifi area it's better to be connected to wifi. Wifi is closer than the cell tower and data disconnects when wifi is connected.
On AMOLED/OLED black background helps because each pixel is individually lit (Black means those pixels are off). In LCDs there is a backlight providing illumination for the entire LCD so as long as your screen is on it won't make a differrence what colors are on your screen.
I'm having a similar issue. I have very low cell reception at work, and I can get maybe 4-5 hours SoT throughout the day and am at 10% when I get home. I've tried uninstalling/disabling apps that use a lot of battery, so hopefully it helps. I'll update if by the end of today I'm able to get 7+ hours SoT (which it seems it's on track to doing).
Edit: For clarification, the apps I've uninstalled that I believed to be using a lot of processing power/ram/battery were Facebook, [Facebook] Messenger, and Words with Friends.

Just use an app like Greenify to block apps running in the background when not in use so you dont havr to uninstall them.
Brightness can have a lot to play on this one. I tend to go with manual brightness so there's no ambient sensors working all the while the display is on, and if you are doing anything where you can cope with lower brightness then drop it.
Keep an eye in battery stats for "google play services" as this can go nuts. When this happens sometimes clearing data can help.
I also found that using google+ to backup my photos caused a lot of battery drain.
I have not found facebook or whatsapp etc to affect my battery much personally. I use stamina mode when i'm out and about to keep the phone at sleep while the screen is off.

At my house I get just enough LTE to cause our S3 to constantly switch to LTE then loose it and switch back to H+. Battery life couldn't make it thru one day. ATT removes the screen that let's you control network mode but I found a backdoor method to lock the phone out of LTE. The phone now stays on H+ and battery life easily jumped 40%. That's the primary reason I held out this time for an unlocked non-ATT-crippled phone--so I can easily turn LTE off.
Well, tried have my phone on over night (for a change to test it).
Everything off (mobile data, gps etc).
Used 7% of my power and every app was closed. When I looked at battery drain, 55% was from cell standby and 40-45% was from Phone Idle.
Tonight I will try charge it to 100% again and then let it be in Flight Mode to see.
I struggled to flatten the battery on my phone the first day 70% of the day with the screen on, no wifi enabled or stamina.
Another test would be to change mobile settings to 3G or 2G to see what difference that makes. Under settings, wireless & networks, select more, mobile networks, then network mode.
I would try the above first before making your phone completely unavailable, especially the 2G.

What is that? H/H+?
GSM - Edge
WCDMA - H/H+
LTE - 4g
But I think 4g uses less power than edge, but it is more than in my area there is 1/5 in 4g coverage, 3-4/5 in H/H+ and 5/5 (always) if using edge.
As I see an better connection gives better batterylife, but 4g uses way less than 3g/edge if same cell signal.
But is going to try it next time I get down to my dad. He got 5/5 in LTE signal. So gonna see if it can stay at 100% over night.

Hehe, ok I understand. But HSPA = 3G. [emoji4] I haven't done any rigorous testing, but I think my stand by times are much better using edge (2G) compared to 3G.

Nope, coverage is about the same. Generally speaking though, 2G > 3G > 4G when it comes to battery life. That's been the rule for years, but as of late, newer radios have become more efficient with 3G and 4G, thus making the difference less noticeable. YMMV. Would be interesting to see your drainage on 3G as well. ☺

I've just purchased an S3 and now notice that my phone battery seems to be draining a lot more than prior. Is this just the constant bluetooth connection to the S3 ?

Standalone mode and remote connection mode are the same vis-à-vis the watch. In either case it's using it's LTE radio, doesn't matter if it's going through the network to connect to a phone (remote connection) or nothing at all (standalone)
The biggest drain on battery life is weak network signal strength. If the watch has to constantly search for a signal, it could be completely out of juice in just a handful of hours.

My brand new Gear S3 is down 15% in 16.5 hours (0.91% per hour!) since its first full charge. Frontier, non-LTE, linked via BT to my Nexus 6P, Auto HR on, and syncing with S-Health. I'm kind of amazed.

Depends on how you use it. I only get a single day, and sometimes less. My watch is always remotely connected to my phone (which sits at home) so LTE is always on. Display is also always on. Both of these add great functionality but drain the battery.
If I'm outside a lot, or driving around town, it'll generally make it through the day. If I spend a lot of time inside buildings, reception is generally poor, it may not make it to lunch.
To maximize battery life, stay within BT range of you phone, disable AOD, turn off mobile networks and WiFi. Turn off location services. Or best yet, put it in airplane mode and DND. Then it'll last forever...
No such thing as two days...you're lucky if you get a whole day.
I checked all the topics (one topic with 2 answers mentions that) and I didn't find an answer to my question, which is:
Is using only bluetooth connection on LTE version watch has worse performance than using watch with only bluetooth version?
Manual says it is possible to change LTE connection to "always off" in the settings, so theoretically battery life should be the same.
And while you are already here, one more question: LTE connection allows only to recieve calls and sms, no app notifs as standalone, right?
I am facing a decission which one 46mm classic shall I buy, and LTE is only 20$ more so I wonder, as I would use eSIM ocasionally, if I should get more expensive one (price for plan taken into account, low cost).
Most worrying are stories that right out of the box LTE versions battery life is pathetic; not even reaching 18hrs not even connected to LTE, while bluetooth versions are doing much better. Any chance that updates changed these problems?
Thanks in advance.

I am also wondering which one gets the best battery life. Hopefully someone has an answer, so both of us can make a more informed purchase decision.
It is unlikely anyone can really answer your question authoritatively because I doubt anyone here has BOTH an LTE and non-LTE watch such that they can be compared with otherwise identical setup and use-cases.

These are information I was able to find:
*There are some posts over the net of owners claiming that LTE has poor battery life, which is changing every update - once for worse, once for better. There are some news today saying that latest update made battery life worse.
*There is one topic on this forum saying directly that LTE version with Bluetooth turned on has worse battery life than regular LTE, while some owners post LTE screenshots of getting 2 days of battery life
*LTE versions receive updates later - needs confirmation
*LTE allows to recieve and make sms and calls, and also to use Google maps sort-of. Watch standalone doesn't receive phone apps notifications.
*First days are the phase of watch learning battery habits, usually length of battery cycle extends
That's most important info I was able to find so far where it is not mentioned in reviews. Feel free to add something that will be useful for someone looking for advice and if I wrote something wrong - please correct me.
I ordered LTE version. Gonna check out how it will handle basic tasks.
Also there's one very good discussion about the problem:

Well, it is kinda unacceptable, but i might order two models and gonna compare both of them and return one as it might turn with worse battery life than the other. I want to avoid that, so I'm searching for advice here. If i won't find any, there will be only one thing left for me to do.

You do not need to do that. It is simple logic. BT and LTE will have exactly the same battery life if you turn mobile data off on the LTE model. If you actively use LTE, this will drain the battery in less than 12 hours.

Yes, there is some logic behind that, but surprisingly there are topics like this:
Where are the battery troubles in the LTE models coming from
There seems to be some sort of consensus that the LTE versions of the watch have more battery trouble Has anyone actually given it some thought as to why? When LTE is off it should not make a difference, but it does seem to exist. Is the...
forum.xda-developers.com
FWIW, I have an LTE Galaxy watch 4 (non classic) 44mm. I usually get 36-48 hours with LTE mode on automatic (which means it only connects to LTE when BT is disconnected or there is no data connection from phone, of course if the phone had no data like in an elevator then the watch won't either regardless of it trying to connect to the same non existent data source). If I turn LTE off completely I can stretch it out to 2 full days. But that's my usage, ymmv.
I too have a GW4 Classic 46mm and have experienced battery drain, however, I expected this and am prepared to live with it as being untethered from my phone was THE primary reason for purchasing this model (My previous watch was a Gear S3 BT version hooked up to my S9).
I hate being out for a run and having to carry my phone with me. It's much more convenient, for me at least, to head out now with my Buds Pro and stream Spotify and not have to carry my bulky S21 Ultra (even with an arm band).
Mind you, when I say battery drain, I'm using mobile data, GPS, AOD and BT, so it's expected.
It's not a deal breaker as far as I'm concerned as I chuck it on the charger while in the shower and by the time I'm ready to wear it again, it's back to the battery level it was when I walked out the door.
Everyone's use case and expectations will vary though and opinions are like aholes; everyone has one.
Hopefully the efficiency of the watch and it's OS improve over the next 6 to 12 months but I, for one, am happy with mine.
If you're searching for the perfect piece of tech, thats akin to searching for that elusive pot of gold at the end of that rainbow.
Happy trails!
No Change in battery life if u use automatic mode. I have Galaxy watch 46 mm and my battery remains on 45 percent at the end of day when i use bluetooth or LTE only mode. Original glaxy waych is bigger and has bigger battery with less functions and hence lasts longer.
I totally agree with this. That's why I got it. But nevertheless the battery life isn't long enough for a 2 hour run if LTE, BT playing music are active. It really is frustrating. I actually power the watch off totally and only power up just as I begin a run.
I have both. I have a watch 4 classic and a watch 4 lte. This is not to say my experience is better, worse, or the same as anyone else's but here is what I've dealt with. The Bluetooth only lasts about a day and a half, sometimes 2. The LTE version was at least a day, until after a couple of updates. The LTE version over heats on me whether I am on LTE or not or even have it turned on. I can't run many apps without it overheating. Turning on LTE without the watch pretty much turns it to airplane mode. If I just leave it set to automatic and not really do much with it other than let it be a watch and receive notifications. Now the battery life is horrible. I can take it off the charger and drive to work, a 10 minute drive, it's already down to 92-95 percent by the time I clock in. By lunch, it's asking to go into battery saver mode. That's with LTE mode in automatic. Turning it off is not better. I tried to track a hike and it overheated on me. I got the LTE version because of the fall detection just in case anything happened on the mountain trail. I had to turn LTE off to continue and even then battery drained like crazy and the device was sluggish. Totally defeating the purpose of me paying for it.It wasn't that bad in the beginning but if course, it's worse after my return period ended.
has anyone with LTE model and using auto mode that lte will stay on no matter what? mine for some reason won't turn off the lte connection even when my phone is connected to it. very seldom do i see the bluetooth only with my phone around. am i missing something?
I've notice that watch being connected to wifi with LTE on auto has much worse battery life. Ergo - i set LTE on only purposefully while choosing to go out without phone, otherwise i choose LTE always off. When i choose LTE off it switches off without problem. Does restart help?
When I went to bed, my watch was on about 60%, left it in the shelf and thought there would be enough juice for the next day but was down to 45%, when the watch isn't on a wrist, surely it goes into a low power state?

Me too. Though I tried setting LTE to ON and then to auto and it seems to now deactivate when connected to by or Wi-Fi (at least from the quick settings pane or can I see somewhere else if lte is active?)
HI all,
Are there any updates if there are differences in the performance between LTE in BT mode and BT only?
@Bo_Doc, did you manage to find out, did you buy both?
I am currently with LTE 46mm. Airplane mode is turned ON and then BT turned ON manually to connect to the phone - calls, messages, notifs - all good.
I bought the watch on 10.02.2022, so pretty new. Here is my experience with the battery life.
With the settings below my battery lasts around 43/6 hours - almost two days. That's the maximum for me.
LET - OFF - I haven't activated a mobile plan
GPS - OFF
Wifi - OFF
AOD -OFF
NFC - OFF
Brightness - around 40%,
Bedtime mode - scheduled from 00:00 to 07:30 + Power saving for the same period
All smart gestures (raise to wake, gestures for answering/dismissing calls and notifications, quick launch) - ON
Notifications with turning display on for Viber, Gmail, Slack(not always), Phone, Yahoo Mail, FB Messenger, Calendar, Clock, Phone Messages) - ON
Vibration - OFF
Samsung Health monitoring features - OFF (only steps counting )
I have several calls during the day, and a light to moderate number of notifications.
What's your opinion, guys? Am I doing well in terms of battery life, or is my battery underperforming for its capabilities?
P.S. This is my 3d charge cycle.
Hi i have owned Lte galaxy watches then Lte galaxy watch 3 models and now the watch 4 Lte
my post is to comment on watch 4 overheating when connected via gsm networks ....in strong signal areas the watch does not seem to get hot and overheat.
.but if i move to a weaker signal area the watch overheats .....by switching from 3g/4g mode to just 3g tge watch no longer overheats and the data connection is still fast enough to.be useable .......if you are suffering from hot watch syndrome try settingx/connections/mobilenetworks/networkmode/3g only ...it may help
Yep, 3G only can cool the watch sometimes. Cheers
More info on GW4 CLASSIC IN 42 and 46mm both with Lte which overheat in poor signal areas or long 4g / 3g voice calls
Well i bought a 4g classic in 42 and one in 46 mm back when they were first available in August 2021.
Both worked fine but if i used an esim in a weak signal area the watch got hot within 2 minutes and shut down as it was on full transmit power over 4g mobile network.
The battery would drop massive amounts in a short time and the watches would give up and overheat....
So i made notes of the furmware ...photographed the inside of both ...filled out a return and sent them both back for repair as this is an issue much reported on the net..
So git them both back and looked at the firmware version ...and looked inside ...
Hmmm well it looks like Samsung know how to fix tge fault with a new redesigned rear cover and a firmware
Update
So as Samsung are quiet about the issue i would recomend that even if you can live with a hot wrist ...you
FILL OUT A SAMSUNG REPAIR / RETURN FORM ONLINE then your pride and joy watch can be collected and samsung can upgrade the thermal heat sink design and reduce the max tx power the watch uses to reduce tge overheating.
I now dont get thermal shutdowns on any of my watches but lte enabled does reduce battery time by about 50 percent
So my advice return to samsung before the warantee expires
Note.. this is just lte models ......bluetooth only models i do not own
Ok GW4 42mm classic Lte only no bt wifi gps etc
In a permenant data trandfer to keep link over 4g up is achieving 5hours 35mins from 100percent charge to flat.no iverheating
The 46mm version is getting an extra 2 hours of call over lte as the battery is larger capacity again no overheating.
This should be a worst case as i selected the weakest signal strength location to force the watch to use a higher tx power output
If i disable 4g/lte network connection and use just bluetooth only at 30 feet to the phone its linked to i get
42mm classic watch 4 one day 19hours
46mm classic watch 4 about two days
This shows how much power 4g /3g enabled watches use ....
My old original samsung watch r805f as the battery was larger could manage 3 days
Note ...my tests are with a data transfer taking place all the time to simulate a link to a watch and were done so see if i could cook the watch overheat if after a repair return from Samsung
In a real world with some bt some lte some wifi not sure what yiu may get ...?
The point i am trying to make....
When cell coverage is weak the phone increases its output power in an attempt to maintain a connection. A weak signal uses 10 times as much energy as the strongest signal, so it can drain a battery very fast if you are on a call, and it will still drain the battery when not on a call because the phone periodically reports its location to the network so an incoming call can find your phone. To further complicate things, if you periodically lose signal completely the phone sends a "where are you?" page to the network to reconnect. This is sent at full power. If there's no response it repeats the request periodically, with longer and longer waits between pages. However, if it reconnects and then loses the connection frequently, the pages are sent frequently without the longer waits, again draining the battery.
Incresed signal strength generates more heat so if in a low signal area turn off mobile networks to save battery which in a watch is small and it also reduces heat generated by the transmiter power curcuits
You claim to have pictures. Can you post them? Also can you show what you mean by redesigned rear cover? I have the 46mm LTE on Verizon and it overheats a lot.
Hi all,
I'm about to get a Galaxy Watch 4 LTE 44mm but i've been reading a looot of bad reviews about battery life. Since most of those reviews are from 2021 or so, are you guys experiencing this issue? Would BL version be a better choice or should i stay outside Exynos and go for a TicWatch Pro 3 ?
1 it's not Exynos
2 there are loads of posts here about it, use search..

I leave lte, bt, and wifi running all the time. I turned off aod. I use a black watchface and I typically make a couple of phone calls and answer a few texts during the day. I'll get home with 30-40% battery left. However, if I stream Spotify for 3 or 4 hours, or make long phone calls I'll be down to 10 or 15% battery. This is my first smart watch and I got it just to see if it would allow me to be more hands free and have less interruptions grabbing my phone from the truck or from another room. I didn't even consider battery life when I bought it. It's worked great for me. I'm happy with the watch. My only complaint is it gets hot and shuts itself down to cool off. If you're on a call you get disconnected. Minor inconvenience I guess.

Thanks for the feedback, well it's better than what i expected
Coming from a Amazfit GTR 3 Pro. Still comparing some models

Exynos W920 - https://semiconductor.samsung.com/n...s-new-with-the-exynos-w920-in-galaxy-watch-4/
And thanks but as i said the feedback is usually old and Samsung usually provides updates every month (or almost).
