use wifi or not?

From a battery perspective, should I use wifi? Most of the time i'm at home or at work where I have wifi. I also have good lte coverage at both. Speed aside, will I save battery by not using wifi or not?

You'll definitely save battery by using wifi when you can connect. I love the speeds over lte, but it is definitely a hog...

i also had boost of battery using WIFI
Using unlimited data plan makes me to consider using 4g, but I found that Wifi consumes much less battery.

Use wifi. The battery savings are huge.

yes i cant stress enough, wifi saves enormous amounts of battery so use it when ever possible. the difference is like night and day.

Compared to 3G
I've been leaving my wifi off since I have unlimited data and the 3G is pretty fast in my area, no 4G yet.
I've had pretty good battery life lately using only 3G, I'll have to do a few tests and see which one and I'm a fairly heavy user I'm approaching 4GB this month and none of that is tethering

3G or Wifi
Tested watching a streaming video of 22 mins
on 3G I lost 13%
on wifi I lost 8%
Wifi wins, of course standby is probably different, if 3G vs wifi loses this badly I'd have to imagine LTE vs Wifi is a slaughter battery wise

Actually I found something interesting...
For some reason, even when I am home using Wifi, the battery drains faster than I thought. Where I live is like a strange signal spot. If I turn off my WiFi I can see my TBolt constantly switching between LTE and 3G, sometimes it stucks on 1xRTT for a while then goes right back to switching between connections. If I am at work (downtown LA) where the LTE is pretty well covered, I still use WiFi at the office, the battery BARELY drain at ALL.
My theory is that even when WiFi is active, the phone somehow STILL does the LTE/EvDO switching on the background does draining the battery.
If somehow the devs or VZW can tell the phone to STICK to EvDO/1xRTT instead of going back and forth with the LTE while WiFi data is on, it'll solve the problem.
Also just FYI, I have the latest radio and BMAF 1.5 remixed.

pretty much correct. at least on the gsm side, when i connect to wifi at home, i can no longer see if the phone is on 3G or EDGE. but it definitely switches back and forth to those networks, while staying on wifi, you just dont see the icon switching, but its definitely happening. i dont see why cdma and 1x would be any different.

if this is the case then why don't you just turn data off when you are on wifi.

Better yet get juice defender and automate it . Its very good app. Right now it says I'm almost adding fifty percent on to my battery.

I seem to be bucking the trend here, but LTE is working better for me than wifi. I usually have a good signal, so that's part of it.
The other part is that my wifi may be eating more juice than normal because the TB and my router may not be playing nice together. Ever since I added the TB to the network, I've had to reboot the router every coupla days. Before the TB, it was solid weeks on end.

Has anyone who is still having trouble on with batter on wifi set their wifi sleep policy to "Never" sleep? Mine is set to this and if I am home most of the day I will lose very little battery through out the day.
I believe by default the wifi is set to turn off after a period of time or when the screen is off so during this time I believe you are actually reverting back to using the vzw network. To turn wifi to always on go to settings>wireless>wifi settings>hit menu>advanced. The sleep policy is at the top, change sleep policy to never. This my reduce battery while not connected to wifi so I always use the power control widget to turn my wifi off completely while I am away from the house.

Oh yeah this is very important, set wifi sleep policy to never greatly increases battery life. Otherwise it switches back to 3g when screen goes off and drains way more battery. This is very important to set this otherwise you wont see the increase.

Is strongly recommend switching to cdma only if yore gonna use WiFi and plan on saving your battery. Otherwise what's the point. I personally don't even bother using WiFi just use LTE only mode. I'm getting better speeds than most WiFi connections using my LTE.

[Q] Anyone notice crazy battery drain when signal is spotty?

I'm currently out at a client site, but it's super bad reception here in the conference room they stuck us in. First of all, no 4G in colorado springs, so i disabled LTE, and hit CDMA in the network settings.
3G is near impossible inside, so i usually get 1X, and voice connection is next to impossible also.
So i noticed that from unplugging in the morning at 7:30am. at around 2pm, my battery was already down to 10%!
And i didn't even use it.
I did see from my battery usage, that Android system was ABOVE screen in power usage.
Anyone have the same issue?

I've had the same problem with EVERY phone ever, even non-smartphones have this problem. The lower the signal, the more the phone will scan for a good signal. If it has no service, it scans very frequently. If you're on a smartphone, it's even worse because then when the phone does get service, all the data apps attempt to use what little bandwidth you do have all at once. If you're in an area with poor coverage, put your phone into download mode or disable the data connection. Nothing short of putting a network extender or new tower will solve this.

Yes, but this is typical of most phones really. Searching for a signal, acquiring it, losing it, etc, uses a lot of battery. You just have to disable data. If there is wifi available, then use that, if not, just have to wait until you go outside. I have no reception in my building at work, if I leave data on, my battery is dead in a couple hours, on wifi I can go all day

Yes and my phone got very hot in my pocket at the time as well.

I have this issue at work. I get anwhere from 10-15% battery drain an hour. I have determined that it is NOT because of the data signal though becuase I can turn that off and still get about the same excessive drain. It appears to be because of the voice signal. It varies anywhere from -85dm to -115dbm and is constantly changing. When I get outside of work environment, everthing is fine again and battery usage returns to normal. My Droid X did not have this issue.

-115db? How do you have signal at that rating? lol. Phone gets to about 1 bar when it reaches 101 for me.

I have the same issue in my office. I just barely get voice/text service. My solution is to turn off mobile data and plug my phone in to balance out the battery drain from the weak signal. I know it is bad to have my phone plugged in all of the time but it is better to be able to have sms and not have a dead phone when I am done at work.

Yeah. Tell me about it. I am using Mobile Signal Widget to measure this. When It gets that bad, a little android face appears in the widget and it is crying.

YES! easily drains 10-15% an hour at a local pub that has 1 bar of signal.

It makes perfect sense... Your phone is fighting hard for that signal.

I drive 50+ miles to get to work and I always notice it drains a lot during my commute even when not used. I figured it was because of all the cell site swaps and searches bc I'm sure there's some spotty areas.

Same experience. Dropped to 5% in 9 hours yesterday when I forgot to turn off data while at work. Today, I'm still at 75% after 9 hours with data off.
Juice defender solved this on my fascinate. It turned data on only once every 30 minutes. But, I can't get it to turn my data back on with this phone.
I really wish data signal aggressiveness was managed better by the operating system. It could be a real boon to the average battery life. Perhaps a smart developer could come up with some sort of "conservative" governor for 3g/4g connections. Rather than increasing power draw, it could just "sleep" until a stronger signal is detected... Imnuts? Is this even possible or just a pipedream?

I can't reach my dad on his cell phone while at the pentagon for obvious reasons. He has to turn his phone off during the day or it'll die in a few short hours, as a previous poster mentioned searching for a signal is a huge battery drain.

Strange. I did not have this problem with my OG Doid or Droid X in the same environment. Maybe the Moto phones simply have a better radio than the Charge.

Yeah for some reason, the samsung radio are junk. I have my Droid Charge (personal) and an Lg phone (business) and the lg blows the sammy out of the water. Now i am in 3g fringe (forget about 4g), and the sammy loses data all together while my lg still has the signal. I hate when i am trying to search for something on the charge and it says connection failed or network unavailable retry. Even when i call verizon, they all have me do a reset and stuff, and nothing works. The best answer i get is that iam in a 3g fringe area. When i tell them that my lg works and still has signal, all i get is silence or hmmmmmm. Gota love it. Yes they exchanged the phone with a new one and it still does the same thing. Forget about battery life. I actually carry 3 batteries with me and on a good day i only use 2 but usually it is 3. Before anyone says use wifi, unfortunatly we do not have free wifi where i work. anyway that should not be the answer to this problem. We are paying for a service that i can barely use.

I went through the whole VZW customer service thing both on the phone and in person. They weren't much help but they gave me a brand new phone and it does the same thing. Then there were a lot of suggstions on different forums suggesting apps killers, turning data off, turing on 3g only data, rooting, trying different ROMs, battery clalibration, etc. None of this helps. The kind of drain I am seeing goes way beyond any benefits I would see out of any of these things. For example, I am at work now. When I left the house, it takes about 15 minutes for me to get to work. The rest of the time I have been inside my work building. I have been on battery for 2 hours & 24 minutes and I am at 76% already. Thats >10% drain per hour. When I am outside the building it is more like 3-5%. VZW customer service never suggested this as a problem. They DID suggest that 4g uses more battery but that is not the problem. I have proved that time and again by simply turning data off.

Hmm..sounds like a bad phone..I am in a fringe area at work and it definitely kills by battery faster but..it's only like 8% and hour so I still get 10 hrs a day or so...in a bad area. In a good 4 G area..I will get 24 hrs or so out of the phone.

Wow, that is the complete opposite of my experience. I've never had good signal with any LG phone - from flip phones to smartphones. Samsungs in my experience are middle of the road - not great, but not bad either. Motorolas usually do well, but there are certainly exceptions. HTC seems to be fairly good, but again, there are exceptions. Oh, and I did have one Audiovox phone on VZW, and it was garbage.

Haha you can whine about it in my rage thread

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.

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...

Nexus 5 has it and its doing its job saving battery

Sorry for digging up such an old thread, but with LTE my Nexus 6P, it switches between HSPA and 3G. When turned to 3G, nothing changes. Would that mean I would save battery?

[Q] Better LTE management - read on!

I've had this thought for a while, but haven't found any practical way of implementing it, perhaps having it out to the broader public may help.
LTE or 4G, as we all know, is fast and great, but it also demands more on our batter than good old 3G.
These are some of the scenarios in which I would love an app, or OS be able to make smarter decisions about the network.
1. When connected to WiFi - When connected to WiFi, our battery life improves when compared to 3G or 4G, but I find sometimes that even though I'm connected to WiFi, my cell network is still connected to 4G (at home, my 3G signal is full bars, but 4G is 3/5), thus, wasting a bit of battery.
2. When phone is in low data use state, or lengthy sleep - Often, when I'm in the office for example, my phone sits there in standby for hours at a time (my emails come onto PC, plus I wear a moto360 so i check notifications there). In these modes, LTE is of little use for me, yet it can often spend hours in LTE standby.
I've looked into IFTTT, and messed with other software apps, but I always end up with the same conclusion, that is, this would have to be manually done...
does anyone know a way?

If you have a root you can do with with xposed and gavitybox (smart radio). I think some other modules can do it as well.

Let me guess, not on Telstra. Battery life on mine with Telstra is superb, even with 1-2 bar signal. I guess that would be because it is a stable 1-2 bar, unlike the issues I had previously with Optus, were my phone would drop signal very often in built up areas

Yes, not on Telstra, but that is besides the point here. This is not an AU specific thing. I travel internationally a lot for work, and this would be the same when I'm overseas. In fact, not complaining about battery life at all, just think that the way the phone manages its connections could be improved - this is not a problem on the Sony, but on most phones.

Good tip. Not rooted, not intending to.
