I just bought a galaxy s3 last Friday because I loved everything about it and the sales representative made it sound like it beats the iPhone 4 hands down. Now I'm starting to wonder if I should bring it back because of the poor battery life. I sent a total of 12 text messages and made absolutely no calls and had 2-3 bars of 4G LTE service and my battery was at 32% in 5 hours. I had it in Power Save mode, too. Now I'm having problems getting one bar of 3G service and my battery just keeps wearing down. I'm going to be heading to college in a few weeks and my phone is my only source of communication and i don't want to be attached to wall because my phone can't keep a charge for very long, plus I get poor service there as well.
Is anyone else having problems with their battery life? Or is my poor battery life primarily from a lack of good service?
Oh and for the record, my brother had an iPhone 4 and he switched to this phone and wants to go back to the iPhone because his iPhone could make it almost 2 full days without a charge and he would only get 1-2 bars of 3G service.
Maybe I should return my phone and go to the iPhone 4? Any thoughts?
My S3 seems to have decent battery life. I charge it at night, and usually have no problem going all day. If I play games, without it plugged in, I seem to get 4+ hours.
The phone just came out, so expect updates. Make sure you don;t have any battery killers like GPS on (when you don't need it that is), or active wall papers.
From what you said above, that sounds off. I would go into a Verizon corporate store and ask them. When I had my DX with a similar problem, they did a battery test (I think it was making a 30min call, and checking battery life after). They swapped out my Battery and seemed to be much better (not sure if that is standard policy, or not, but they will take care of you).
Hi, I have a new S3 and the battery does not last as long as my trusty S1. However the S3 has LTE service which the S1 and the iPhone does not. The nature of LTE causes the battery to drain faster than a 3G phone. LTE is a new technology not only for us but for Verizon as well. What I mean to say is that there are many parameters that can be set on the LTE base station that are simply not used at this early stage. It is up to Verizon to tweak the cells to keep the phone from doing so may cell reselections. Each time the phone decides to reselct a cell it eats the battery.
I trust that Verizon will tighten up the network as more LTE devices come on line and eat up network resources doing needless cell reselcetions.
You also forget that the iPhone display is half the size of the S3 (intentional exaggeration), the S3 uses multiple cores, and unlike the iPhone, it is a true multi-tasking phone. The S3 would have similar battery life if it performed the same tasks as serially as the iPhone.
I would check apps, unload anything ad-supported (pay for the non-subsidized app), and ensure Bluetooth and GS services are off if you aren't using them. If you have a weak WiFi signal, your phone has to work harder to make that connection. Same with your radio signal.
With all of that said, I easily get a full day of usage with my S3, averaging at least a daily conference call of two hours, and up to two three-hour calls, gmail, gcal, G+, and extensive Exchange email and calendar access via Touchdown. I have used the phone extensively in my area of 3G coverage, but battery life was the same when I traveled and was in a 4G-saturated area for a few days. I use very few non-stock apps. No live wallpapers, no weather, social, or news widgets, etc. Widgets can be evil juice suckers.
I think you can reasonably expect eight hours of usage with moderate use, including numerous phone calls, SMS, email, and Facebook and browsing in moderation. If you are using your phone as a toy, you are watching youtube or movies for hours, or you have the screen lit constantly to check Facebook statuses, just plan on that 4.7" screen to eat up the battery fairly quickly.
If you are new to Android, you will figure out how to use your phone to maximize battery life, just as I would no doubt require some time to adjust to the iPhone.
I don't dim the screen much, but I think it's too bright at 100%.
I get what you guys are saying, but Samsung and Verizon had to know that too. They know how we use our phones and the high and lowpoints of their system. They should have specified a larger, more capable battery ala the droid Maxx. You mention getting 8 hours. 9-5 is not so great. I have a lot of apps on mine, and my time seems to be about the same, I am reaching for the charging cord around dinner time and there is still an evening's worth of use ahead.
On my S3, I keep my WiFi, BT, Mobile Data and GPS on all the time with power saving disabled. I still get a full day of battery with plenty to spare when I go to bed. The only time I put my phone on charge is overnight. The main culprits for high battery consumption are background sync and poor signal, followed by power hungry apps such as live wall paper, touch/vibrate, etc. Disable Live wall paper ... it gets boring after some time and you can always turn it on if you want to brag to a iUser. Disable touch/vibrate and other unnecessary gimmicks. At home, make sure you place your WiFi router in an area that gives best signal to your phone and use WiFi, even if you have unlimited 4G. WiFi is just as fast for the kind of work you do on a phone - and more importantly - WiFi consumes less power. When you are mobile (out in the open), signal strength is usually very good .. if not, there is nothing much you can do about it except to use a vehicle charger if you are in a car or use some other power source if possible. If you have WiFi at work, use that instead of mobile data. If not, use OpenSignal app to get the best mobile signal. Go to Settings - Accounts and Sync and disable all syncing except Gmail (which uses push). If you have any other email accounts, I would recommend forwarding them to gmail so that you are getting all your email from one account. If not, turn on sync for other emails one at a time. Some email providers provide more than email sync - you can disbale such components if you don't need the. If the mail service does not support push mail, it will use more battery. Check your battery usage app to see what the major culprits are. Your screen should use the most, followed by Android system and your most frequently used apps. Most apps should not consume a lot of battery. If they do, something is wrong with their setting or you have too many background apps running. Stop/Disable/Uninstall whats not required. Some apps may do their own background sync - configure such apps not to use data. An app like Avast security (free) can be used to block internet usage to apps that don't need internet
All good advice. I go all day, too. In fact, I am going on 18 hours and I have 40% left, and I don't take any of the precautions you do. I guess if I needed 24 hours, I would invoke power saving mode and shut down GPS, Bluetooth, haptic feedback, etc.
I can't really say someone is doing something wrong if they have a bunch of apps and crapware loaded, but there are trade-offs for having your favorite game running 24/7, constant twitter and Facebook checking, etc. People use their phones differently. I think those of us who use their phones for business more than entertainment may understand a little better as we see first hand the effects of power-hungry usage, like constant video streaming, youtube access, and Netflix. I'll check out youtube in a pinch, but I'd rather bring my Kindle and an iPod on long flights and layovers than rely on a movie I may have downloaded.
I get good battery life because I don't jack around, I've used the same four or five core apps for nearly three years, and I have a good sense for what affects my phone's performance. I can tell immediately if an app is affecting performance and battery life (I can tell Chrome affects battery life, because it acted the same way on my S2 as the S3, so I unloaded it). If I determine I need an app, I test it, see how it affects the device's stability, and check battery life.
turn off the wireless, and use only the data connection.... the wireless ***** the life out of my battery... I figure until they release a patch to fix it Ill just use the crap out of their data.
Not true. I see virtually no difference in the battery life when I am using wifi (about 90%) and data. I guess if you are leeching a weak wifi signal from your neighbor it might.
Congratulations on the purchase of the Galaxy S3, kjo14!
This is a great device, but the battery does drain quicker than 3G devices since it does run on 4G and is also on Android with a sizeable screen.
This video http://bit.ly/NjTxJe will give you tips on how to preserve your battery to make it last a little longer.
I also like to keep an extra charger in the car and at work to help in desperate times for my Android.

The others have covered most of the bases, with 4G, screen brightness, etc., but here are a couple of things I've noticed.
Weather apps should be set on "manual update", or once daily. My favorite weather app was the second most resource wasting app running.
If you just have to use Facebook, use the mobile web page. The app was also draining my battery.
If you aren't aware, go to Settings/Applications Manager/Running. Just those two apps were really zapping my battery.
Some apps can't and shouldn't be stopped.
Many apps can, and suck battery if they aren't shut down.
I never use the music or book or game apps, they remain open even if I never open them. Facebook, internet, play store navigation, all can be closed if you are not using them.
I say it again, Apple has a user friendly way to close apps when you are not using them. Samsung dropped the ball, this should be easier.
If the Android market want to compete and beat Apple, do a better job at crossing the 't's and dotting the 'i's.
My son says, "If they are going to challenge the Giant, better be able to take it down."
I'm Tech enough to make it work for the next 2 years, then I'm getting an iPhone. (should be on an iPhone 6 by then)
BTW I bought 2 spare batteries and a charger on Amazon for about $35. The charger will charge one battery and has a USB to charge the one in the phone. The replacement batteries run as long as the OEM battery so I pack one as a spare and rotate. I've gotten real good at slipping the back off. Still stupid. My younger son watches video on You Tube or plays games for hours and his iPhone 4S lasts much longer on a charge.
These apps do not use battery while in the background, this is the way Android works. Apps are loaded into the RAM so they start faster when called upon. Using CPU cycles uses battery (which apps stored in RAM are not doing). When you kill off an app that is stored in RAM, it will then use CPU cycles to reload the app if the OS sees fit, therefore actually using more battery, along with showing your phone down. iOS is not a true multi-tasking OS, which is why the make it so easy to kill off apps. If you do not know how to properly use a task killer, you will cost yourself battery life, as well as possibly end critical processes.
My S3 makes it through the day without any issues, without using Power Saver Mode I end the day with 35-45% with regular Slacker Radio streaming, phone use, texting and even a occasional game play..
I have been surprise of how well the battery has done compared to my Thunderbolt, my TB needed a extended battery to survive the day that my S3 had done with the standard stock battery.
Another thing I have never seen a user of a iPhone get two days battery life with regular use.. If he can get that kind of life that is incredible..
I am really not thinking using the Battery Saver Mode is the best thing because the device would have to monitor all the options that it is meant to turn off to save battery life, the feature itself seems flawed... I am not using the Battery Saver Mode or any other application to monitor battery and I haven't had any issues with lasting out the day.
My lady friend asked me at what percent my device indicate a low battery and I told her I couldn't say because I charge it at the end of my day and I haven't dropped to the level to see the low battery notification.
Try disabling all the battery management options in the OS and if using any apps for this remove them and see if things works out better.
