I have a question to everyone. I understand wifi drains less battery than 3g. But what if you are not surfing the web? Which would drain less battery while using the phone but not surfing the web?

Depending on what you're doing...
If you have a strong 3G signal, that's probably your best bet.
If you leave wifi on, it will continually search for available networks, which drains battery. However, if you're somewhere with little or no cell reception, the phone uses more power to search for a cell network.
If you're not actually using any online service, airplane mode is unquestionably best.

At home I have weak 3g signal. Overnight, 8 hrs, WIFI conected to home network uses about 6-7% while weak 3g about 40%.
I leave Wifi, 3g, GPS, and bluetooth on all day and use my phone a lot and my battery lasts a whole day. We shouldn't have to **** around with enabling settings anytime we want to use the damn thing. If however you are running low on juice, then at that time you should start turning things off, and lower the screen brightness. Note: the auto brightness setting uses more juice than manual settings.
Hello. I picked up my s3 this morning after having charged that night. I unplugged it at about 1 in the morning, with airplane mode on, bluetooth off, and WiFi connected. When I woke up though at 10, the battery had dropped down to 80 percent while in standby, with no recent apps even running. I'm not sure if this is normal or if it's a battery problem but it's quite annoying, because it drained 20 percent in 9 hours of standby. Any help is appreciated.

Wow, so my drain is a bit extreme. I'll see what else I can do to try and fix this. Thanks for the quick reply though.

I will drain the battery and charge to full again tonight. After I check it in the morning, I'll note what the battery stats say is draining it. I don't want to do it right now because it's been influenced by my usage today.

This looks similar to my problem, and happens only when connected to certain WIFI-networks.

The things that it's say are draining it according to the usage stats are: WiFi, android os, phone idle, and android system.

Hmm. This could be my problem, but I'd need to try out some other WiFi networks to make sure.

Maybe caused by ~LG8 OTA combined with dual-band WiFi network?
I posted this over in another forum, but copying here to see what you all think...
..............
I don't know this for a fact, but I've read some things that lead me to believe the issue may (again, not confirmed), MAY be related to the recent ~LG8 OTA push. The root (no pun intended) cause is related to how the SG3 interacts in 802.11n band Wi-Fi networks that utilize multi-band (i.e. 2.4Ghz combined and 5Ghz running simultaneously).
One of the "features" of ~LG8 was to remove Advanced options for Wi-Fi networks, switching the connectivity logic to "automatic." If a GS3 is in a multi-band 'n' Wi-Fi network, it MAY be switching back and forth between bands, thus chewing up battery without actually pulling any data.
This is unconfirmed, so don't shoot the messenger. Can any of you validate whether or not the Wi-Fi networks where you see excessive drain is indeed a multi-band 'n' network?

This sounds like it could be a possible cause. I'll have to try out some multi band n networks in the next few days or so and see if there's any effect.

Ever since I got my SGS3 last year, I noticed that WiFi would drain battery rather than save battery. For whatever reason I always got better battery life with WiFi off rather than on.
I noticed a lot more wake locks too. I don't know if it was because with a solid WiFi conneciton, apps tend to refresh a lot more than they normally do.
Enter the HTC One. I have noticed the same type of effects. I've only had it for 2 days but I am noticing better battery life without it.
So I want to collect some data using a poll. Do you get better battery life with it on or off?
Off..

Can you please add your vote to the poll? I just want to resolve this for people complaining about the battery life. It might be their WiFi.

My best setup is with wifi always on, but I set it up so Tasker turns mobile data off as soon as my phone connects to my home or office wifi network.

Shouldn't mobile data turn off automatically when WiFi connects?

It goes inactive, but it doesn't actually get 'turned off'. If I don't have it turned off, what happens is when my wifi goes to sleep then mobile data goes back on. I don't want that.
of course you get better battery with Wifi turned off. but doesn't Wifi consume less battery than cellular data? my balance is to keep Wifi on ANYTIME i'm in a trusted wireless network and manually toggle off cellular data when I'm using Wifi.
It burns battery when it isn't connected and on but I get better battery with it on and connected

So I am only averaging around 3 hrs of screen on time. I have lux and greenify always active. 4G and wifi on every 15 minutes and have Knock-on turned to off and I still see people getting 5hrs and even some more. What kind of tips do you have?
Sent from my VS980 4G using Tapatalk
Faulty phone, or some weird app issue, i would factory reset and play around without installing anything. If you still get those numbers, get a new one.
This is the only phone I've ever owned that easily lasts all weekend.
Im at 15 hrs with 2hrs screen and 46 percent left. I drive all day and play music via Bluetooth and it was sunny today so screen was at 80 brighteness.
Get a wakelock app and see if something is draining your battery

For some really really weird reason, I get better battery life when everything is enabled. I'm stock not rooted with EVERYTHING enabled, and I mean all the at&t bloat + LG bloat. I even have knock on enabled lol
Right now I have 14h30m of usage and 4h of screen on time, and I still have 40% left. Also I've only been on WiFi for about 2 hours today, the rest is all 4G

I would recommend leaving data off cause i had mine on all day and at 38% with 9hours on batteryv3 hours screen on time. Data seems to be sucking the life outta my phone. Oh well.
Screen time is not absolute. Playing games for 3h or watching movies for 3h is comparable to reading a book for 10h, because of a thing called GRAM. Don't let those stats fool you.
Dang maybe you should try enabling everything just for the fun of it lol and I mean absolutely nothing disabled!

Exactly! With RR3 i get 3hrs and a little more. Browsing 7hrs. It depends what are you doing.
My Experience:
1. Greenify
2. Clear RAM (Widget LG)
3. Use Wifi, limiting open 4G data
4. Screen Brightness 50%
But these things only improve a small part. Encourage use a ROM MOD :good:
I'm running cm 10.2 and got 4 hours screen on, 9 1/2 hours up with wifi on all day, got home with 49% battery left. I use greenify and wakelock detector. Maybe run a custom ROM. I prob couldve got 5 maybe 6 hours screen on.
Sent from my LG-VS980 using XDA Premium 4 mobile app
you should be using Greenify...
There are alot of apps that are constantly pinging the network that could be causing the extra battery draw
I.E Facebook, Instagram, WhatsApp, dating apps, Hangouts, Skype, Drive, Box, Dropbox and any other messaging apps that go outside of basic text messaging through the carrier
Edit: Or Tapatalk...i just noticed your using that. Gonna check in every so often for new messages.......I bet you just have a TON of apps running in the background....
I just don't understand. I'll do a factory reset once kit kat comes to Verizon. If it ever does!
Sent from my VS980 4G using Tapatalk
Oh, and for the Sprint variant, i disabled/froze some LG apps, Sprint apps, and 'VuTalk". Boosted my battery life like crazy....
As long as you have a constant cell signal I think the battery life is great. With my T-Mobile version I don't get nearly as good signal on the days that I work because the phone is using Wifi Calling for the cellular signal. On weekends when I have full strength signal I easily get the high screen on times.
Did a factory reset now actually. Lets see if this fixes anything

Carefull with what apps you put back on......
Few games. I have Greenify, xposed, 2x battery, lux and a few other minor apps but none of the rest run in the background.

Auto brightness, change your mobile network to 2G when you're not using data, go to settings > WiFi > advanced and make the WiFi always on *only when it's plugged in* and turn the always scanning option off, go to your Google account in the settings and turn off sync for anything that doesn't need to sync, make sure NFC is disabled, increase the refresh time on any of your social apps, and enjoy your battery.

I really hope I'm not the only person having this issue. Wifi calling is causing 35-40% of my battery usage on my device, even when turned off. I turned it off last week as it was extremely annoying having to constantly go into the wifi calling settings to re-set the location of my wifi network (I would have consistent wifi calling authentication errors until re-setting the location). Now even with it off and ALL authorized wifi networks removed from wifi calling I am still seeing this huge battery drain.
Anyone else see this happening on their devices? Better yet, anyone know of a fix or work around?
Check to see if connections optimizer is on. Turn it off if so.
It was on. Just turned it off. I'll report back with my findings.

My battery drain while on wifi calls has been really good. Only 5% or so for a 30 minute call. Might be that optimizer... Keep us updated!
Sent from my LGLS990 using XDA Premium 4 mobile app
I know I was seeing moderately bad battery life and it ended up being the optimizer. Would definitely try that first as others said.
After turning off the optimizers this morning i am so seeing 36% battery usage and 9+ hours of stay awake time on the Wi-Fi calling app. It is still disabled and the authorized list is blank. I'll try rebooting the phone and wiping cache.

This is my thread on the Sprint forums regarding wifi calling. Please add your complaints and gripes so they see how many of us are having issues with it. If we don't speak up they will think all is well.

After a full charge i am not seeing the wifi calling app on my battery usage. Looked liner it was the connections optimizer.
Sent from my LGLS990 using Tapatalk
When I first got the phone, the WiFi calling kept giving me authentication errors and would not work, and then after a couple days the phone just shut down on me and never turned back on again, while the battery got hot. I exchanged my phone for a new one, and haven't had any problems since.
On a side note, wifi calling has allowed me to get rid of my Airave, which Sprint gave me for free about a year ago because I was getting constant dropped calls at home.
I'm getting huge battery drain and I actually stopped the process. Its using up more than my display.
After a little more investigation, it would appear that the issue was 2 fold. Connections Optimizer was causing an issue however the root of the problem appeared to be having *any* wifi networks in the authorized list even when Wifi calling was turned off. Now that the authorized network list is blank and wifi calling is disabled, it no longer shows up in battery usage and my battery life is much much better.
Reading the success of dkratter, it makes me wonder if a re-image might correct the issue. I did enable wifi calling when Sprint was having some server issues with the authentication.
