Phone battery drain - Samsung Gear S3

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 watch does not seem to last a day. I've heard you should get 2 to 3 days.

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.

My Mom's GS3 is dying fast. I think it's LTE but I may be wrong.

OK, so my wife and I both have GS3's through T-Mobile and our batteries last very long. I'm a heavy user and get a fully day while my wife is a light user and easily get's two days. My Mom on the other hand has her GS3 through Verizon and her battery is dying in roughly half a day. She is not a heavy user at all. In fact, her old Droid 2 would last longer than her GS3 which really has her frustrated.
I think it may be due to the fact she doesn't get a good 4G signal at work and at home. In fact, she gets 1 bar at work if she's lucky. She also said the phone is constantly bouncing back and forth between 3G and 4G while at work. She took it to Verizon today and they swapped SIM cards to be sure that wasn't the problem. Obviously that didn't work because I'm posting here. I will see her on Thursday and she want's me to look at her phone.
Do you guy's think this is most likely the reason as to why her battery is draining so fast? Also, if it is. Would there be a way I can show her how to disable 4G so her battery lasts longer?
It's most likely 3G and 4G switching back and forth or a rogue app. For to turn off the 4G it can't be done without rooting I'm pretty sure.
No, it's because you have task running. I had the same thing happen to me. If you exit an application by pressing home, the program will continue to run in the background. I had gallery take up 38% of my battery life. If you press the back button, it will FC the application.
Good bye HTC Rezound, hello Galaxy S3!

I'm on verizon as well and I find that my battery dies extremely fast. Full charge in the morning and by bedtime its just about dead, that's with moderate use. Some things that I have found to help is I generally keep bluetooth, and gps off unless I need either. I keep power saving mode on, and really minimized what Sync's through my accounts.
It's not exactly the answer you were looking for but it should help you until a more long term solution can be figured out.
Does anyone know how to turn 4G off?

Low tower signal will kill the battery very fast. Frustratingly fast. I have Verizon GS3, have very low signal at work, and I burn 8% battery per hour when phone is idle. With almost no use, my battery is down to 30% by time I go home.
At home I have good tower signal and my battery drops very slow in idle, maybe 1% per hour. At both work and home I have WiFi connected and set to keep WiFi on during sleep always. Therefore I don't think it's data traffic / sync causing the issue. Instead its hyperactive radio hardware or firmware killing itself as it constantly finds/loses tower connection. The only thing I've been able to find to reduce the drain is going into airplane mode... which is obviously a terrible option.
Hope Samsung can improve this self devouring nature in the future!

go to the playstore and download "phone info" open it and go to device information
Swith the " lte/cdma/evdo" into cdma auto (PRL)
I also turn off 4g at work due to weak signal
VERIZON GALAXY S 3
I believe its a signal search at where she spends most of her time. At my work the signal is very bad and the phone goes from 100% to 20% in 10 hours without even touching the phone. Now I turn on airplane mode and it never drops the battery.
She can disable the data and find out how much that would save her
First make sure it's not a rogue app by going into Settings -> Battery, your top 2 battery usages should be Screen and Cell Standby. As long as you don't have some random app eating away at your battery then it's definitely signal strength related. Does she have Wi-Fi available at work? If so make sure she connects to it. I have a Verizon S3 and the battery life on this phone is better than any Android phone I've ever owned (and I've had a lot). I leave GPS and Bluetooth on all day and can easily get a full day with mid to heavy usage. The biggest thing would be to get her on Wi-Fi if available. This will stop the phone from constantly trying to poll data off a poor signal and significantly increase battery life. If no Wi-Fi available, then the above post would come into play, Phone Info app and switch into cdma to keep it locked into 3g will help, but only if there's a decent 3g signal. If the 3g signal is weak also, then you're not going to help anything, and she will just need to remember to turn data sync off while she's at work.

Try switching batteries to see if she has a defective battery. If thats not the case, then make Verizon give her a replacement S3.
Add me to the list of people who think its the signal search in low service areas.. I disabled 4G with the Phone Info app and my phone lasted way longer than before..
Since you pointed out she has a low signal, I wouldn't be surprised if that's the culprit..

Ahhh so it wasn't the battery itself?
When you got a replacement S3, did you go back to the same store where you had originally purchased them from or tried a different store?
I disabled 4G today at work with my stinky cell signal and my battery nose dived like usual. Therefore, if you have no signal, 3G/4G doesn't seem to matter. The radio hardware will still destroy itself happily.
Anyone know of a widget my Mom could use to disable data completely while she is at work?

Pull the task drawer down and uncheck mobile data. Why do you need a widget?
You might have a system process called "gsiff_daemon" draining the battery. I have that problem and others have reported that process has been draining their battery as well. Or it could be other have mentioned already, signal switching, rogue programs, etc.
Today at work I ran with mobile data off. I still had a really bad battery drain. Therefore the voice 3 g radio must be responsible. Not much we can do about that unless a new firmware comes out.
Another battery tip...

There's also an option in the settings>developer options to restrict how many processes are running in the background, and to kill an app after leaving it. The only problem I've noticed with the second option is that the fb app won't allow you to post a status, I think because it causes it to start a new activity, which kills the main fb activity when you leave it. But limiting the background stuff seems to have saved some more juice on top of only using 3g.

Naw man, at home I have good cell signal and have almost no idle drain. At work I have terrible signal and it drains like nuts. It's not an issue with apps, processes, services, etc.

Does gsm really make that much of a difference in battery life?

I have been looking at this thread http://forum.xda-developers.com/showthread.php?t=1725921 and see all these people with att gs3's getting all this awesome screen time of over 5hours. Some go into the 7s!!! I can barely get 4 my record is 4:52 and I have never been able to duplicate it. I have sync turned off, power save, debloated, you name it. I know CDMA eats more battery but to give them a 25% better battery is normal?

I think lte is the major battery killer if you have it in your area.
I got what was probably my best battery life so far yesterday I had 30% left with 4:15 screen time including time spent watching streaming videos, listening to a couple podcasts, and playing like fifteen minutes worth of games. This was using Wi-Fi with Bluetooth and GPS turned off.
Also I think the auto brightness kills battery life too. I have the brightness slider in the notification bar and tweak it to match current lighting conditions. In dark rooms the auto setting seems too bright.

Last charge cycle I went 26hrs w/4hrs 52min screen on...LTE was on the entire time. I agree leaving the device on wifi might gain another hour of sot, especially those in fringe coverage areas.

I don't know. There might be something to it. I have the Galaxy S3 on T-Mobile and I am amazed at the battery life. In fact that ability was one of the things I told my sister who got the Galaxy S3 on Verizon and her battery life sucks compared to mine. I checked her power settings and they are the same as mine. I am by far the more "POWER USER" type. Mine is stock - got the Jelly Bean update two weeks ago and have noticed no difference in the battery life with the OS update.
The only difference is when I am home, it live off of WiFi. I have good WiFi in my house. She doesnt have WiFi but VZ's cell network as we all know is much bigger. She has more bars then me.
She thinks it might be a bad battery and is planning on taking it to the VZW store and getting it swapped out. I doubt that is the issue. I was with VXZ before had the Original Droid and HTC and Samsung phones. Last was the EVO 4G and with that puppy it was....
Wake up (phone plugged into AC adapter) go to the car and right away plug it into the car charger for the drive to work once in the office plug the USB into the office PC. And do the reverse going home. If I was in a situation like in a Doc's office or at the Mall or restarunt.....I would be @ or below 50% within an hour.
My Galaxy S3 lasts all day with ease even on days where I am out and about and not @ my home's WiFi

Lte vs 3g battery life

Will the phone have a longer battery life if the cell modem is set to 3g vs lte?

Yes, in my experience with the S4 it's a pretty big difference UNLESS you get a very strong LTE signal. I'm on tmobile and now have the N5 and use the 3G setting which is HSPA/+ Plenty fast for me for what I do. When I want some extra speed I'll kick on the LTE
Does anyone have a more detailed answer for this? I just got this phone yesterday so I haven't been able to find out myself yet, just with 5hour battery life from 100% to 4% on what will only be half of its normal day I'm looking for anything to help right now till I get a battery case. This phone is one of only two to have a LTE radio that is supposed to use 30% less power than usual so I'm wondering if that makes it as efficient if not more than 3G for idle in your pocket to light stuff like FlipBoard.
it would depend on the quality of the data connection. im in brooklyn nyc, and use lte on my nexus 5 exclusively, used to use it on my nexus 4 as well. with 3g(hspa+), on both my n5 and n4, i average about 4-4.5 hours screen on time. when using lte, i average about 5-6 hours screen on time on both my nexus 5 and 4. after noticing this difference, i use exclusively lte on both my devices, as i average an hour more screen on time when using exclusively lte.

Serious battery drain can have many reasons. One is having LTE on, syncing on(if you just booted it up, and input your Google account and let all your apps sync and download, its gonna drain your battery fast the first time), having locations on and wifi enabled. If you are in an area with poor reception, your phone will drain more trying to find connection.

Thanks for the information. That's what I was wondering but I couldn't find anyone that had already tested this with these new radios. If I get the time this weekend maybe I'll do my own test in detail to compare LTE to 3G. Am thinking of using a TV episode on Netflix and see which makes the battery drop faster over the 30 or so minutes.
Slightly off topic, does anyone's WiFi show as always on in the battery monitor even if its been off? Still trying to figure out my battery drain issue, if it even is an issue with just me, I bought this phone knowing it had a small battery.

Seems that's a whole other debate on weather leaving that on or turning it off helps battery life. Apparently if you turn it off then apps that want your location will turn the GPS on and waste battery (looking at you Facebook...), but if you leave it on the phone just tells the app your location from WiFi networks around you.
One thing I didn't think about is I had added my work WiFi yesterday but it wouldn't connect to it, wouldn't tell me why but I'm assuming it's because of bad signal as I'm a valet outside and the WiFi is from a bar across the street so I forgot about it but WiFi was left on with that network saved, my Nexus 7 can connect to it on most days and any laptop has no issues but with this being a phone I guess it doesn't have a big enough antenna. So I'm wondering if now that I deleted that WiFi network, and I always have my phone set to not notify me of public networks, if my battery won't die so fast today.
And now I'm just rambling but I just looked at my screenshot I took yesterday of battery use before plugging in at 4% and WiFi isn't even being shown on top six things that used the battery, lowest one being shown is a Chrome process using 3%.
EDIT: Well off to work now with my phone 100% charged, will have screen 100% (am outside in the sun), BT off, WiFi on (disconnected, no saved networks nearby, open network notifications off, always on during sleep, scanning always available, avoid poor connections, and WiFi optimization), LTE on/connected, NFC off. So lets see how things go. It will have tons of screen on time as all I do at work is read through FlipBoard, then if I run out of things on there I move to FB. Lets see how this goes...

[Q] Poor cell signal draining battery? How to get those 8+ hour OST?

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.

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. ☺

Question battery issue need help

So recently my watch has gotten bad in battery. This morning I picked up my watch from the charger and it was sitting at 100%. fast forward 4 hours later and i'm getting notifications to turn on power saving mode. the only thing that i have on this is the modified version of the samsung monitor but it hasnt been updated to the latest. another strange thing is that when i check the battery stats it say 7 hours and 26min left but only 15% available. I already reboot the device and same thing happens. any advise? im using Oneplus 8t+ model kb2007 and watch is the classic LTE version model:sm-r895u

With 'mobile networks' eating up most of your battery, it appears that for some reason you're spending a lot of time on LTE rather than connected via Bluetooth - which will naturally kill your battery.

hmm odd. i do have another picture where the status of mobile network is 14.2% use. but will recharge and turn on bluetooth only. what does LTE do with watch anyways?

It connects to mobile networks independently of your phone - so that you can use all of the connected features of your watch even when away from your phone (if you have service set up for your watch - if you don't, I suspect it still hunts for service, hence the battery drain). It's very power hungry regardless, which is why you should use Bluetooth when you can.
