I just wanted to post on the XDA forums that there is a thread to help determine what is causing the "heat + battery drain" issue(s) on the Lumia 920.
http://discussions.nokia.com/t5/Nok...n-ATT-Overheats-Battery-Draining/td-p/1606012
Specifically, we've seen fairly normal battery drain when using applications, but when LTE data is introduced the battery continues to drain at a rate of 7-8% per hour even after the applications are closed. For example, streaming something like Xbox Music or Netflix over the LTE connection (wifi OFF), the phone warms up considerably and the battery continues to drain at a high rate even after those applications are closed. The same applications behave normally over 3G or Wifi, and the battery drain is not present afterward.
The "fix" so far appears to be disabling LTE altogether.
• Open Dialer
• Punch in ##3282 and hit Call
• At the Field Test menu, choose more options via the three dots (lower right)
• Select Settings
• Under network type, select "3G only". UMTS should be set to "Automatic".
• Change the "Toggle ENS" setting to OFF
• Back out, power off the phone, and power on again
Definitely interested in hearing other's reports on this issue. Specifically, does this happen with ALL Lumia 920 phones? Is this specific to this particular model phone? Is this a Nokia issue, LTE chip issue, or WP8 issue? Was this introduced with the Portico update?
Thanks.
Upon further testing.........
Disabling LTE is *not* the ultimate fix. Yes, it does help keep the battery drain down to more reasonable levels, but it does not solve the problem. I've subsequently tested with the little brother phone -- the Lumia 820 -- to see if the issue is on all WP8 handsets, on all Lumia phones, or even limited to post-Portico update phones (in other words, did Portico make this issue).
After some thorough testing, I can say with confidence that this issue is specific to the Lumia 920 and not necessarily all WP8 handsets or Lumia phones.
Detailed thread here: http://discussions.nokia.com/t5/Nok...Overheats-Battery-Draining/m-p/1795212#M43837
I am currently working with Nokia to find a long-term resolution to this issue.
Please keep us updated, I'm very interested in knowing how to fix this problem! ??
I found that disabling bluetooth helps out.
Battery drain
To help reduce battery drain I do the following on my WP
I get a connectivity shortcut app. There are a few options available in the store. Anyway I pin airplane mode, Bluetooth, Wi-Fi, and Location on my home screen and turn them off when I'm not using them. Turning off location turns of GPS, so you must enable it before launching Drive/Here. A lot of battery issues I think have to do with the phone being to aggressive (power wise) trying to search for signal. Whether its Wi-Fi a Bluetooth device, etc. I also disable Tap+Send (NFC) because I never use it.
And I go into background tasks and I block every single app from running in the background except the ones I am sure I want to run. Remeber the list where you can block them is for apps that want to run on a timed schedule, they can still run in the BG if you home screen out of them. For me the only one I allow is MS Weather (for the live tile). Disabling Nokia Drive/Here seems to help battery life for some people.
The biggest battery saver I did was forwarding my other email accounts (Gmail & Yahoo!) to Outlook.com, and then set that to only look every 1 hour (instead of the stock 30 minutes). My phone went from lasting 1 - 1.5 days to over 2.5 - 3 days with my typical usage (light usage).
I try not to use Live Tiles, or lock screen pictures unless I really want them (like weather for instance), as they help drain the battery quicker.
Anyway Nokia is really on top of their game so I think they will help contribute to WP to eliminate these issues. The only non-software related issue with the 920 is the dust in the FFC, which personally does not bother me but I could see how it might bother others.
##3282 isn't working for me after yesterday's update. Lets see how I do with the battery today!!!
The earpiece on mine does not work I can't hear anyone and top of phone gets warm I have sent it to nokia repair.

Thanks for the tip!
I also have 5-8% per hour drain. (actual offi. release .1308...)
all off, sync, loaction, WLAN every thing, fresh reboot, phone on my desk, not working with it, about 2 lines H signal.
when i switch to airplane mode....1-2% battery drain over a complete night!
its also no problem to activate airplane mode ON and afterwards WLAN additionally ON, then about 1-4% over a night!
i tried everything i found on the inet.
and i have my white L920 since Dec.12! (i did a "hard" update over PC in Feb. and also the the last release over the air...nothing changed)
so now i'm checking if this works for me and post results
I'm located in AUT with an unlocked, unbranded GER L920.
and we dont have LTE til now...maybee thats the problem..?!

That is great. To bad that we whom have received the latest OTA no longer have access to that menu.
really?
I'm on FW 1232.5957.1308.0001
and WPH 8.0.10211.204
I don't need to change the network type within ##3282 menu, also worked for me in normal network settings.

So then how do you set your network speed?
u don't need access to ##3282...its also possible to "limit" within settings/network. (##3282 NOT working within f.e. Rapdialer!!)
I limit it to "2G" only when its more importand to have less battery consumption than inet speed
limited to "2G" in my region it shows me afterwards a "E" on top.
On this PIC i found in the inet is "roaming" deactivated.
I have to activate "roaming" also when I'm within my own network to have inet access (and the "E").
In my town, network operators share their mobile radio transmitters.
I limited direktly at my provider the access to a "real roaming network" for example a swiss network.
Because i'm most of the time near the border
maybee not possible in your version or provider?
I'm on a free GER version.
Definitely trying this tonight.

My experience is that, I reset the cellphone and after doing this twice and connecting to the internet and waiting for one hour, Microsoft gave me an update for my battery saver and since that time everything is ok, including the battery. I always believed that the updates have problems to be installed completely most of the time, so it's better to reset or download it via the computer and instal it with a cable( using Nokia Software Update). But if it doesn't work, please don't panic. The updates are coming and just be sure that you have reset your device without choosing the setting backup, for you must start afresh. Good Luck.

Hello everyone, I have a few questions / issues regarding this phone and android in general, here it goes:
Voice Talk: what are the differences between the two apps (the one with the green and the one with the blue background colors)? They seem to do the same things to me.
Energy saving: the energy saving implementation doesn't seem too "smart" to me. I'm cool with setting reduced energy configurations like lower brightness and turning off bluetooth etc when the battery treshold kicks in, but I'd expect it to restore my setup once the battery level goes above the treshold again. Atm I have to manually undo all the changes that the battery saving functionality does, basically once a day. Isn't there a "smarter" app that restores my settings before the energy saving mode kicks in?
The battery: I've streamed 30 min of music from the device to my car's bluetooth stereo, and it removed 26% of the battery charge. I'm on fw KE2 cause it seems that KE7 is even worse when it comes to power consumption. Still, isn't it too much?
Volume: I've turned it all the way up both with the side button and inside settings -> sounds (all 4 of them). Still, if someone in my office is talking I miss a sms reception etc. It never happened to me when I had the 5800 express music, so I'm not deaf
App notifications: I left my phone near my bed, there is at least 3 out of 4 bars of 3G signal, facebook is set on 30 min updates, accuweather on 3 hours, info-costs every hour, the phone never turned off nor lost the 3g coverage, yet it missed completely or partially a LOT of updates
App settings: app settings also seem a bit random. I have an app called noLed to show led notifications on the screen when it's locked. I had enabled it, checked the "start noled after phone reboot" and all, and even if the phone never even rebooted, after a day or two I went it and the first checkbox (activate NoLed) was misteriously turned off...
Thanks everyone,

Not that I'm not following your logic, it just seems kinda silly to have 3 apps for doing something that 1 app would be enough to do. For example, it's like having Street View as another external application, even thought it's just clearly a Maps "add-on".

I'm particularly interested in a response to the energy saving that is stock on the sgs2.
However what i want to know is if the energy saving is active, or whether 'energy saving enabled' simply means it is ready to cut in when battery gets down to set target.
Any response to the above questions would be appreciated.
Ta in advance.

As far as I've understood, when it says 'energy saving enabled' in the notification panel it just means that the feature is turned on, but it doesn't necessarely mean that it's gone into 'energy saving mode' already.
My issue with it remains, I don't want it to disable account sync, bluetooth, turn down the brightness etc, and the day after, once the phone is recharged, I have to re-enable all of them...

Got it figured out.
Voice command is for when you're sitting down or something and can give the phone your total attention, while Voice talk is for when you're driving or something.
In Voice talk you can enable 'driving mode', which reads out and incoming texts and numbers of the phone which is calling you.
Even with that disabled, you can just say 'Hi Galaxy' or 'Hey Galaxy' and it will start listening to your commands.
(useful while you're just driving and don't want to be distracted by having to hold down the home button (ahem iPhone) or tap the Tap to speak button)
Still a bit redundant (why not just have voice talk?) but at least there's a difference
I now see what you mean about sync being disabled after leaving power saving mode.
Had a scout about and can't find a solution to this.
Anyone have a solution because this is very annoying.

I'm a bit puzzled by the battery life. I mean, afterall they advertise the various components of the gs2 as battery saving (for example the actually turned off pixels of the super amoled, or the dual core).
So, by logic, if the more advanced parts of it are energy saving compared to other less advanced models, why isn't it consuming less battery?....
Any more info?
I have a new question, is it normal under KE2 that the wi fi can't catch the signals almost al all?
At university I couldn't even detect the network, while the guy next to me with an iphone4 had full signal strength. On the train I had 1 line and it kept disconnecting, while my mate with the nokia 5800 express had no issue with it.
Even at my house going from my desk where the router is to my bed right in front of it, it already starts to drop significantly.
Another issue that I've noticed is that sometimes even tho there is 3g coverage the apps won't refresh. For example, AccuWeather hasnt refreshed since the day before, or manually firing a refresh of the contacts in my WhatsApp list ends in a "update failed, try again later" message, but after rebooting the phone it magically works right away...
Hi all,
The Wifi on my SGSII is constantly scanning even though it is connected to my home wifi network (a WPA/WPA2 PSK secured connection on a G band router). The signal strength is "excellent" and I have the phone sitting right next to the router. Further, I have network notification turned off ( unchecked) and under advanced settings, my Wifi sleep Policy is set to "never".
Sprint users have reported exactly the same problem on the Epic Touch 4G" (http://forum.xda-developers.com/showthread.php?t=1272226 ). Has anyone else been experiencing the same issue on their ATT SGS2 ? I would be very grateful if someone could post a solution for this issue.
Thanks in advance

PS: My wifi setting screen looks like this genteman's ( except i have network notification turned off)

Scan rate is bumped up significantly when you're in the settings menu.
Have you confirmed via logcat that it's scanning frequently outside of the settings menu? It shouldn't be in that case - but without logcat it's almost impossible to tell.

Entropy,
What should I be looking for in logcat? I have Betterbattery stats installed and according to that, Wifi scan time is 8+ hours even though Wifi on time is only 2+ hours. That doesn't seem to make sense, but what do I know.
I am running UnNamed 1.3.1.

I believe BBS is reporting scan time improperly. I've seen that in a few threads.
Sent from my GT-P7510 using Tapatalk
You're probably right, except now scan time doesn't even show.
I have also observed this on my phone.
I have a Samsung Galaxy IIs, using a Sony Ericsson MW600 BT handsfree as well as a Pioneer car Bluetooth handsfree system.
I have not measured anything yet, but I notice that when the Wi-Fi scanning is going on, I get significant disturbances on both of my Bluetooth hands-free sets. Listening to music is without a hitch, but talking on the phone (Norwegian GSM - operator Telenor) is terrible.
i also noted this after installing the OTA update to 2.3.6 today. I just rooted mine yesterday after reading 54+ pages to make sure i understood everything. i had a cappy and loved installing new roms but have not taken the plunge yet on the sgs ii. I haven't noticed a huge difference in battery yet, but it has only been a couple of hours since the update.
What ROM are you running? You can edit the build.prop to change how often it looks for networks. It is the line "wifi.supplicant_scan_interval=xx". I set mine to 180 which is 3 minutes, some ROM's set it really low. Also the scan rate is bumped up significantly when you're in the settings menu like Entrophy said.
Hi,
I had the same problem where my WIFI was fluctuating.... I dont know if this is the problem/ solution but this is what happened...
My SGS 2 is already rooted and unlocked. I had flashed the Entrophy DD 12/23 first then I had flashed Unnamed Custom ROM. After rebooting the phone, I saw the Wifi was not stable. So I again did a "Wipe Factory Data Reset" and "Wipe Cache Partition" and then installed the Unnamed Custom ROM from the SD Card. My Wifi is pretty stable now.
I am not sure if you guys had this issue when flashing a ROM but this seemed to fix it.

I have written about this wifi-battery drain a while back here in XDA.
When I used to have my Nokia symbian cell phone I used to flash custom roms
and there were a lot of nice new features after flashing.
A couple of the really nice battery saving mods were:
#1: added option to change the amount of wifi milliwatt output from 18 milliwatts (default) to 3 milliwatts
which is more than enough if the phone is no more than 20-25 feet from the wireless router.
(the mod gave the option of 3mw,6mw,12mw & 18mw)
Saves a lot of battery life.
Don't know why none of the DEVS have addressed this issue yet.
#2: added a mod so once the wifi establishes a connection it no longer scans
at all unless the connection is disconnected or lost.
So in other words, the phone only scans for wifi until it connects.
Right now I am connected to wifi with my phone and yet in settings it displays "scanning"
non-stop-constantly even though in wifi settings it displays "connected".
Why should the phone be scanning for wifi if it's already connected? (I have no idea).
Don't know why none of the DEVS have addressed this issue yet either.
Both of these mods really made a noticable difference in battery life
for for me since I do use the wifi feature in my phone a lot.
Hopefully one of the DEVS can look into these issues soon.
Now someone mentioned wifi constant scan, I noticed mine is doing the same thing. I leave the wifi setting screen on, it re-scans every 3 seconds!

Power control - Not likely, unless there is some documented power control already in the driver it's not going to happen. We're in a bad enough state as it is trying to make the chip not fire interrupts at 1 Hz on the Infuse.
Broadcom is one of the least open source friendly chipset manufacturers on the planet - their drivers have NO comments or documentation whatsoever, and datasheets are not available.
The rescan stuff is probably only addressable on Cyanogenmod, messing with it would require source code for the userland wifi management stuff.

As stated earlier in this thread - this is by design. It is assumed that if you're in the settings screen you want to change networks and have an up-to-date list.
I also am having this problem. I am running the rooted UKK6 from entropy512. After turning on my wifi, my battery drained from 90% to 70% in 5 hours with no use. My android OS is running at 80-90%. I don't have any extra apps except for 3g watchdog and CPUSpy and BBS. I do have Go launcher and GoSMS installed. As soon as I turn wifi off, i can see my battery level off under settings. I have searched for the last 2 days for a "fix". no luck.

Try doing a clean flash using "wipe data/factory reset" in CWM
recovery and then see if the phone has normal battery drainage.
(which it will if you flash the UnNamed v2.2.1 custom rom)
Then install one app at a time so you can find out exactly which
app is the culprit that causes your excessive battery drain.
This is the best way to trouble shoot battery drainage issues.
You will see that your battery drainage issue is not caused by
the custom rom, but it is caused by a few apps which are just
not very battery friendly.
The UnNamed v2.2.1 rom is the best custom rom currently
available for our i777 phones and it has outstanding battery life.
Good Luck!

This has nothing to do with this thread - This thread is talking about wifi scanning.
Drain problems - read my known battery drainers thread. A lot of people are having problems, there is no fix, and there won't be until all the people complaining start actually collecting some data.
Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.
Thanks for all of your help (plus everybody else, too)!

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
Has anyone else noticed their Lumia using 3G when it shouldn't be e.g. at home with a working wifi access point?
Mine has done this a few times and because WP7 is so clean and simple it's pretty hard to see what's actually going on - there's no data counter. And to make it worse the data icon shows in the status bar even when wifi is on. Ideally it would show one or the other.
Yes, I notice that too. It could be a bug.

Yup, I think it uses 3G when the phone is locked, as the phone seems to disconnect from Wi-Fi when you lock the phone. Another bug that probably needs addressing.
Yes! This affects me too.
It switches to 3G randomly when I'm on wifi and kills my data without me realising (or shows failed page loads when I have full wifi reception).
It also turns off wifi whenever I lock phone which seems to disrupt/cancel all push messages! Push messaging just isn't working.
So is this problem unique to Lumia 800?
i've noticed this too. it'll also present me with wifi hotspots to connect to, including ones it should be connected to.
as of now, i don't know whether it's an issue with locked or unlocked handsets. my handset was bought unlocked with no branding, but i've noticed some of the bugs i'm having don't seem to happen on network locked/branded handsets.
It's not a Lumia thing, it's just how WP works. Turning off wifi to save on battery use I guess. Android has the same default setting, although it allows you to change it.
I can understand it using 3G for background processes, like you say Android does the same thing.
What I can't understand is it using 3G when I am using the web browser on the phone, and the Wifi icon is lit at the top of the screen.

That's not the case actually, before the firmware update I used to get my notifications, after the update, I don't, I think Nokia did it on the firmware update.
Which firmware was this working in btw?
Oh and turning off WLAN when you have an active connection does NOT save power. It only saves power when there isn't an active connection because the 3G uses more for retrieving background data (eg. regular email, social networking updates) and *much* more for retrieving heavy data. I have tested this on numerous Nokia phones.
^ i got the opposite result - normally i have WLAN turned on at all times, because it always connects to wifi at home and at work. my battery lasted much longer (it lasted the night with 39% left, as opposed to going flat sometime in the night) with just the 3g turned on.
I noticed that wi-fi only stays on after you lock the screen if the phone is charging. Otherwise it cuts the conncetion. Very annoying indeed if you are downloading big games over wi-fi. However I get my notifications and emails just fine in any case. Remeber though, windows phone doesnt support proper push, hence why they cant get skype to recieve calls in the background. Facebook and whatsapp push always comes about 3-4 minutes later than needed.
Another thing that i have been testing for a while on various phones (nokia n9 included, not the lumia because it's too unreliable) and also got mentioned in this tread is wi-fi vs 3g consumption.
So my results are:
with 3 emails 15-30 mins sync or push for one, at least one push service eg, facebook, vkontakte whatsapp etc (where possible)
i concluded that if you just leave the phone there for a day in standby and dont use it, it drains quicker with wi-fi on. Everytime. Every phone.
However when using the internet eg. browsing for half an hour etc. wi-fi uses a lot less battery than 3g.
So only use the wi fi when you need it and switch it off for background tasks. (WP7 does that anyway, for a reason)
Starting a thread to gather all the battery saving tip for the Gear S.
I don't have any yet, it is still 1 day old for me. I am looking at way to disable 3G. And rely on 2G. Anyone know of a way?

I don't have a Gear S yet Nov 7th can't come fast enough but I do have the Gear 2 for now and Wake-up Gesture was a huge battery hog I'd turn that off if it's in the Gear S
Thanks, friend. Manage to find it.
The gear last me from 630am to 830pm with around 16% battery left yesterday. I was using it as a standalone phone without pairing it to another phone. Made a call and received a few sms. 3G and Bluetooth was on all the time. I would said the battery is ok.
Gonna try it today on 2g network and Bluetooth off today.
Battery Life with GPS
If you, or anyone else who has the Gear S, is/are a runner, would you please check out the battery life with GPS on, Bluetooth on (and playing music), and 3G on?
Thanks,
Craig

Based on my last attempt at GPS, which I couldn't find a location without a paired phone, I think Samsung made some kind of screw up here.
Anyway, once it tries to use the GPS, battery drops very very quickly. My guess it that it will last 2 hours max.
Another day with Gear S. Pretty happy with it since it fills up my needs. Fantastic battery life based on my usage pattern.
Still using it as a standalone phone. With bluetooth and 3G turned off (stayed on 2G/EDGE), battery finished the day with 51% left. I unplug it at 630am and plug it back at 1030pm.
Usage pattern for the day are making a few phone call, and a couple of sms. Pedometer keeping track of my steps and warn me as necessary.

Please specify instructions for this and what network you are on too. I'm on AT&T and would love to find this but I don't see where I have an option under connections for this.
So far, I've turned off GP (under connections - at bottom)
Turned off Gestures as I don't want it to light up unless I push the button
Set timeout to 10 seconds which is plenty for me
Since this uses an OLED screen, things that you might want to consider is using certain colors/themes.
1) Black is your best friend
2) If black is not an option, red > green > blue , yellow(red+green) > purple(red+blue) > cyan(green+blue) > white(red+green+blue)
3) use darker shades of colors when an option
Now not sure how much battery life this will add as it depends on how efficient is the screen. But in general, these are the OLED battery saving tips.

US carriers, especially AT&T, have a habit of remove such features in carrier variants. Sure enough, my AT&T Gear S doesn't have this option.
If you don't need full functionality all the time, try power saving mode.
You can tick a box to option mobile network on too - this then allows calls and text messages.
You only get a very basic screen, but the battery life dramatically improves. I am at 56% after 26hrs+ with a few quick calls and sending and receiving a few text messages.
going to try HappeningDude's idea and turn off 3g, not sure if power saving mode does this automatically or just enables mobile network with your already specified settings?
Having the option to change your watch face in power saving mode might be nice though? Although it is mostly black for obvious reasons.

The optical sensor is quite accurate. I compared it with the Garmin Fenix 2 which uses a reliable traditional heart rate straps.
But it wouldn't last longer than ~2hrs of run with the heart rate monitor and GPS on.
I don't expect this watch to last a day of hike. Those kinds of activities are best saved for sport specific watches.
With heart rate sensor, gps and a run app going i lose 30% and hour. In theory, I should get about 3 hours of run time.
Has anyone quantified how much extra power the wake up gesture option uses? I have it off but would want to use it when I cannot touch the button.
