Does turning NFC on waste battery? - T-Mobile, Samsung Galaxy SIII

Hey guys, just wondering, but if I tick "NFC" on, will it waste battery life?
And also, will turning on S Beam as well?
Lol thanks!

yes, any extra service the phone has to run uses battery.. common sense.. might not be a lot, but it still uses battery.

Okay. I kinda knew that it would waste battery, but I wasn't sure,
But thanks!

He didn't ask if NFC uses battery, he asked if it waste battery. I don't even have any NFC devices but I have mine ticked ON and my battery life though out the day with gaming, web, texting, phone calls, and probably some rom flashing is good.

if the service is in use it will use battery, if not than in won't. why even have it ON if you don't ever use it. no point.

It only uses battery when you use it. Not because it's just on. I keep my nfc on all day. It's never been ticked off and it does not affect my battery life.

Nabeel,
It will use battery, not much. It's because off the technology Samsung integrated into it.

I have mine all day long. No extra loss. Was reluctant to turn it on also, but after turning it on and forgetting that I did, no obvious drain. No wasted battery here.

Does it use battery? Of course it does. How else can it know when it's next to a tag. The tags are not powered. The question may be, how much. IMHO, very little... next to nothing.

Its probably like GPS, it only uses battery if its actually being used.

Sorry for digging an old topic but I was doing research on this. Your average NFC receiver will drain about 40-50mA of power when active. Now whether it's active or not depends on the software, but most of the time when it's "on" in your settings it will poll a couple of times a second. So yeah, it drains the battery. But how much exactly?
Contrary to previous suggestions it contributes more than a GPS receiver when your maps/location services are off, because that's when the GPS receiver itself is not on because it doesn't have to poll for satellite activity, obviously. The NFC chip has to be in stand-by though, in case another device wants to use it. When the software is properly programmed it might be a couple mA, spiking up to ~50mA during use. This means it contributes little to overall battery usage, but at the highest level of abstraction it does add up to it.

Battery Life

How do I save battery on my EVO?
Sent from my PC36100 using Tapatalk
turn off auto-sync, turn brightness down to about whatever you can deal with, get juice defender (free in market), get droid wall (also free), get custom kernel with undervolting, get better battery
Juice defender never did **** for any of my phones. The things it does to save battery is common sense, disable wifi, bluetooth, etc. And it kept turning off my data service even when I unlocked the screen.
Buy extra batteries and an external charger.
Run battery down, put in new battery.

My gold star winner gets 2 on the house.
For me, nothing seems to be helping.
I've done everything I could think of or find to try to aid with battery life. I've tried all sorts of different ROMs/kernels, calibrated the battery, went through several cycles before determining anything, underclocked, even got an extended battery...
In most cases, the battery life is very nice when the display is off. Today I lost 2% after an hour (with Wifi on). However, I turn on the display, and even if it's completely idle with the lowest brightness setting, it drains like mad. So I can get a good battery life if I leave it in my pocket and look at it occasionally, but I know that's not what people mean when they say they're getting great battery life.
Something just isn't adding up.
Well the way I saved battery life was the following
CM7 rom
Tiamat kernel sbc
Setcpu for root users
From there I lowered my CPU speed.
Doing this gave me a full day bettery.

Bad batter

this phone sucks, you will have a huge screen but with automatic lighting seems drawn on cardboard, the reception is crap, my girlfriend with a lg optimus one has 3 notches and I travel to 1 here in the bedroom. And the absolute most ridiculous thing is the battery, are practically forced to go out with this and the galaxy's, fortunately, not yet sold, it takes at least 2 refills daily. Check it out and tell me if it does not sell a phone like this ****.

Congratulations on a useless post.
If that's the only battery life you're getting then you should really look at how you have your device set up. I easily get 12-15 hours on heavy use and more than 24 hours on light use (moderate use is somewhere in between). I use auto brightness, and keep bluetooth, gps, and wifi turned on all the time. I have facebook syncing and push email going and I have no battery issues at all. I suggest you take a look at your device configuration and also you may need to calibrate your battery.

Nowhere in what I posted did I say that. Try reading with understanding next time. What I said was I have everything turned on and I still get good battery life, so if yours is lacking perhaps you should take a look at how your device is configured. That a bit clearer for you?....
OP, your post has made my day today!
However battery life depends on how your device usage is. People with carefully set usage patterns can extract the most. For e.g. I use Locale to set a certain profile at night that switches off wifi, data usage, etc. That is one way to maximise battery life.
Edited your title to be proper.
Please maintain forum etiquette. You can get the same exact message across using proper language

Okay let me further clarify myself. When I say look at how your device is configured I mean look at what you have running. Do you have things syncing frequently in the background? Do you have apps installed that constantly wake the device? How many background apps are you running at once. I don't have any special configuration on my device. I have everything turned on as far as bluetooth, wifi, and gps. I use push email, facebook set to sync every 4 hours, weather set to sync every 6 hours, google reader set to "download frequently viewed feeds every hour", currents set to sync every 6 hours in the background (wifi only). With those settings my battery life is pretty good. When I'm not using my phone is drains between 2-2.5% battery per hour, that should give you a bit of a point of reference for what you should be getting when idle. Here's an app here I stumbled across that can show you what's waking your device http://forum.xda-developers.com/showthread.php?t=1179809 Hope this helps you out.
Battery is pretty good to me, under normal usage easily over 24hours.
I have had no problems with my battery or screen, not sure where your setup went wrong but listen to the posters before me and less ranting and maybe you'll make the best out of an awesome device
My battery is great! Better than any other smart phone iv used, signal is great swell and the screen is awesome
I love this phone lol

I see in your screenshot the GPS and the screen were on for most of that time.
And by "on" I mean the GPS was really on with a fix, not just "on standby" and ready to be automatically activated when a program requests it.
No phone I have ever owned has ever got more than about 4 hours from the battery when I have been using the GPS. The simple fact of the matter is the battery will discharge very quickly when using GPS. That's not a fault of the Nexus, that's just how it is.
Bad battery?
That screenshot shows you've been absolutely caning the **** out of your phone. Nothing will have a good battery life with usage like that.

Horrible battery life while just being idle?!!?

I've had this phone for about a month. Started off on stock, and rooted it and flashed different ROMs and kernels. I never really got good battery life with any ROM. Typically I would get around 7 to 10 hours of moderate usage.
I fully went back to stock firmware and kernel using ODIN, to flash 2.3.6. I rooted it and removed some bloatware apps. BUT, the battery life seems so bad.. it's been 2 days, I've done calibration 2 or 3 times.
Leaving my phone idle, in one spot, I lose about 4-5% an hour. 4G Data on, wifi off, 2/4 bars of signal, sync on (only gmail, google docs, contacts, calendar).
But today, I think it got worse, as shown here: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230121.png
Graph: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230126.png
Note: the data icon on top shows that it's on 3G, because I moved out of good signal area when I took the screenshots. The phone was idle in a spot with 4G getting 3-5mbps.
What's wrong with this? The phone is a month old, so I don't think it's a battery problem. I've calibrated 2-3 times since I went back to stock.
Also, don't recommend me to use Juice Defender. I use Google Voice to call and text, so I need data on all the time. And I know this phone can last over a day with data on (my friend has the same phone and it has lasted 2 days on one charge, completely stock firmware).
ALSO, when I press "Android System" on the battery history, here's a list of what it shows:

Actually that would be more of light/medium. Checking facebook every 30mins, a few texts now and then, playing a game for 30 minutes, listening to music for an hour, a call or two about 2mins each, a few instant messages on facebook, GPS use for 5 minutes, and idle for about 5 hours. Brightness at 50% or below. All on data connection, no wifi.

I see easily over 12 hours on a charge with my phone, and i use it heavily... 2 to 3 hours of phone time (at the least) wifi tether here and then, a lot of facebook iming and checking. Reading....
Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

Your battery looks fine. Playing games rapes the battery. Also 4g rapes the battery.
There are ways to improve the battery but like you said... You need to use all of these features.
Go get a spare oem battery or a reputable extended battery.

Im at 52% right now, 34% display, time on 3 hours 14 minutes, and sitting at 1d 1h 39m on battery. Light usage.
Something is definitely draining your battery. As you can see your phone is awake when the screen isn't even on. It's just likely an app you downloaded or something in the background. good luck narrowing it down

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?
Run some actual tests to clarify the issue first..
There. I said my peace
If you tried everything else try recalibrating the battery.
I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.
To Recalibrate Battery (must have custom recovery like cwm):
Charge phone to FULL
(I highly recommend AC charger for this)
Reboot into recovery
Look for wipe battery stats (should be I'm advanced if not main menu)
Unplug phone and restart it
Now FULLY KILL THE BATTERY
(for faster results set mp3 or video on repeat and let her rip)
Fully charge one more time and done
(again I highly suggest AC adaptor)
Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.
Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.
So your post is useless and rather a waste of everyones time even reading. So thanks.
@above
Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.
@OP
As suggested above use cpuspy to check on the cpu when idle,
Sleep mode should kick in within 30sec to a minute.
Also chek my reply a few posts up and follow steps there..
Ignore Realn00b's post
Again:
@Realn00b
Please take the time to read up on batterystats.bin and find out what its for,
You don't need cwm to delete, just root explorer.. its in:
Data/system/batterystats.bin
Also, the entire basis of this is stupidity and was takin way out of context.
Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)
And should only be deleted under very very rare occasions (effecting above)
Your battery percent, is actually the mAh
Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.
The device then calculates from these the value we know as the percent.
Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.
Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks

I originally purchased it for two reasons:
1. For long trips or for when I'll be gaming a lot
2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.
Also, I'm on stock kernel. Everything stock + rooted.
I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).
Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).
It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.

Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend
Deleting unndeeded applications and even replace stock with third party where applicable.

Android is good at managing background tasks etc. Don't use a task killer, it can prevent sleeping of the phone, and constantly kill things that need to be running... Android will start it up again, which is more costly than leaving it running.
Some of these apps can turn WiFi or data on and off according to a schedule, which can be useful, but I just leave mine on all the time. I find the screen to be the biggest drain by far.
My WiFi is at 4% and cell standby at 3%, screen is at 71%.
I'd not recommend. Just download betterbatterystats and keep an eye using that app to see if anything is keeping your phone awake. Remember these are powerhouse phones and not like ordinary dumb phones so expect battery life not to be great.
Simple measures such as keeping brightness low, turning off data when not needed, keeping sync to minimal and such will greater battery life but then things out of our control like poor signal will dampen the battery.

My WiFi is at 4% and cell standby at 3%, screen is at 71%.

Yeah but some users report that they have boosted their battery life to 1,5x or even more, some even got 2,0x and that's very amazing in my point of view. I just want to know does that kind of app ( which Juice Defender is ne of the bests ) harms my HOX or something similar? And does those apps really THAT effective?

I'd not recommend. Just download betterbatterystats and keep an eye using that app to see if anything is keeping your phone awake. Remember these are powerhouse phones and not like ordinary dumb phones so expect battery life not to be great.
Simple measures such as keeping brightness low, turning off data when not needed, keeping sync to minimal and such will greater battery life but then things out of our control like poor signal will dampen the battery.

Thanks but what about Juice Defender?Have you used it? Can you give me some review? Thanks

Well if you don't use the screen... Yeah, standby in airplane mode is likely to be much longer than standby with a useful data connection, synched emails etc.
You can ask the same question as many times as you like, my answer will be don't bother every time.
Or try it.
Your call.

Sorry I can't answer that as I don't use any such apps. I always have a data connection 24/7 so don't use apps to manage any parts of my phone.

I've used JuiceDefender Ultimate on my XE and the app's stats suggested 2.0x power saving. I don't know quite how accurate that really is though. I've just installed it again on my One X.
In my experience, those apps just make your battery life worse. They run in the background, causing the processor to run faster, do more cycles which ultimately leads to using up more power. If you want to save your battery life, set your brightness to as bright as you need it to be, not more. Turn off WiFi and/or Data if you don't use it. Turn off GPS if you don't use it. Kill the apps in task switcher because they usually run in the background as well and eat up your battery life.
I was under the impression that you can leave GPS enabled in the settings, as it'll only be used when an app requests it?

Yeah that's true from my experiences. Minimal battery drain when turned on. I think it's to avoid unnecessary usage like weather apps updating every hour or so whilst making use of the GPS. But it shouldn't have such an impact on battery drain unless your using GPS for long periods such as navigation.

Never understood some people's philosophy on extending battery life.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.
I just bought a bigger battery :good:
I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?
Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....

The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:
i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.

I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?
For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram
I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....
