Default poor battery life?

Other than that it sits on my desk with full 4G coverage all day and still drops quite a bit I think.

Any thoughts?

I don't have it rooted nor do I have any power/battery saving apps. Is that how others are getting longer life or is mine just bad????

Anyone else noticing Avast eating up battery life? I don't see it in my battery life monitor to know what it's doing to mine. Maybe that has been my problem for poor battery life.

If so, anyone know of an alternative to Avast that doesnt' eat up the battery?

How long is everyones S3 taking to get a full charge? Mine seems to take about 5-6.5 hours. That seems a bit long to me, but I came from Blackberry, which could charge in about 2.5 hours!

My old iPhone 4 got better battery life. But it's not the huge gap that I thought it would be given LTE and the 4.8" screen. Overall, I'm happy.

Just the fact that you can compare an Android stock battery to an iPhone is a good thing lol.

sorry to make a handful of posts, but I wanted to give an update in case others are having similar battery issues. I am excited to say I uninstalled Avast yesterday and am getting amazing battery life now! It's hardly even draining at 1% per hour now. Before it was 5% or more!! And that is with WiFi on and Power Saver mode off!! I hope this will help the speed it takes to charge as well.

Anyone know of a good anti-virus/malware program that won't eat up the battery?

I usually download and install an anti-virus app, run it once, and then delete it. I usually restart my phone then, too.

In the 2+ years I've had a smartphone, I've never had a virus or any other spyware.

What ive started doing is when im at work and not using my phone for a good few hours, i switch on airplane mode. Thats started saving me HOURS of battery.

If i dont use airplane mode all day, i still get good life. 12 hours medium-long use. So pleased with this phone.

I have got a custom kernel (see signature) and I have undervolted it by at least 100mV which will of course have a slight positive effect on battery.

Being rooted is a good start as you can use titanium backup to freeze apps you never use that may use a bit of power etc.

I ran mine down at the end of day 3 with some browsing and such before taking the screenshots. Disconnected Saturday morning, took screenshots Monday night.

I'm a new member here, hoping for a little help.... So far, I've had a terrible time with the battery life on my new Galaxy S3. I can't post screen shots yet, being a new member, but here is a quick example:

I charged the phone to 100% overnight. Today, after just 3:15 on the battery, I was already down to 75% remaining battery life. My screen time was just 13 minutes... All I did was check my emails and looked at my fantasy baseball app.

The battery usage screen:

Android System 65%
Cell Standby 15%
Screen 7%
Android OS 5%
Maps 3%
Android Core Apps 3%
Exchange Server 3%


This seems crazy to me that the Android System/OS and Standby would rip up that much battery life. Any advice would be greatly appreciated. Thank you in advance.

There's a thread about this over at xda:
'Android System' draining battery fast! - xda-developers

Turning off mobile data helps, but it's not a very good solution. Lots of other information in the thread, but no definite solutions.

Definitely try rebooting it after any install/uninstall. Also Better Battery Stats is a great app (have to pay for it but I think it's only 2-3 bucks) that will help show any possible apps that are causing wakelocks and keeping your phone awake.

I recently uninstalled Avast anti-virus and noticed HUGE increase in battery life. Sync will drain some battery as well if you have lots of google or other shared data. You can change how often it checks for new info or if you have ability to a steady wifi during the day I found it doesn't drain near as fast as it does when using sync over the LTE network.


I also have the turned off most of the motions and keep the screen on low auto, but that's all the battery saver options I have checked.


I hope that helps.

Ill wake up at 6am. Go exercise until 730 playing music from my library and then stream Pandora when in the shower. By the time I get to work at 9 my percentage is in the 80's (low 80s) feels terrible to me. I dont think I could make it 8 hours at work and if I can its going to be just barely.

Well, I tried juice defender just for fun. Just like on my DX, it drained the battery faster than without it.

I still think the gs3 needs the option to shut off mobile data when the screen has been off for 15 minutes or so. I guess I'll try to do it with Tasker, since I did buy it a while ago.

I don't understand what some people do with their device(s) to not get at MINIMUM 10 hours of battery life, even with at least 2+ hours of screen time...

I say, without a shadow of a doubt, turn off notifications for social media, and I bet you get better overall battery life. No one needs to check social media that much, surely. Don't people work during the day? Honestly, rhetorical of course

This is about right for me. I get about 12 hours of my battery. Keep in mind when you streaming Pandora your using 4g. So even thought your using the same amount of data as you did with 3g its at much higher bandwidth so your using more battery. The thing that kills my battery the most is the Face Book app. I could be wrong but this is how it was explained to me

FYI, I was running Bean's ROM when I was having this issue. I flashed NoSympathy's VRALG1 ROM and haven't been having the problem so far.

Hey guys, new member here.

I got my S3 a week ago and since day 1, I have thought I had battery drainage issues. Granted I've been on the phone constantly during the first few days, however, today with light-medium usage (texting, camera, no wifi, 4g for an hour), I got down to 5% with 9 hrs unplugged and 2 hrs screen time.

What do you guys think? Should I exchange it for a new phone as I am within the 30 day policy?

Every few days I notice this unusual case where, without plugging in, my battery actually goes UP one to three percentage points. Anyone experiencing similar circumstances?

Now if only I could get the phone to do this on command... B-)

As for the guy using 95% in 9 hours, how bright do you have your screen?

And stop using Task Killer. It sort of helped on Gingerbread and earlier versions of Android, but ICS is quite adept at managing its own tasks. Also make sure you don't have too many apps updating in the background.

I don't understand how, but it appears that you aren't on 3G, LTE, or wi-fi. Maybe this has something to do with your battery's charge draining so quickly.

My brightness was set at about 70% today because i was outdoors most of the day and had to see it in the sun. I turned off wifi and LTE since I did not need it at the time. I have sync off for all my apps so I don't think that would be a problem.

My phone just went from 100% to 83% in less than 2 hrs! It was mostly on standby, with wifi on. Is this normal? I have since deleted the task killer.

I'm so impressed by this phone. I got some spare batteries on ebay but I do twice as well with this as I did with the Rezound. I'm a heavy user and I do great with this. I was so surprised.

I use the power saving built into the phone along with GREEN POWER PREMIUM.

Amazing how much I can do on a full battery. Sometimes I even get through a whole day and I use my phone plenty.

Wow, I don't know whats wrong with mine...

I've only had it two days, but with light use (getting/replying texts... using browser a bit) mine seems to be burning battery at a rate of 10% an hour. I don't even really have any apps installed yet, have Wifi off, etc.

If I am using it, with a web page open or something I can literally watch the battery drop 1% every couple of minutes. I just did a full recharge, and after an hour its down to 93%, and thats with only 6 minutes of screen use . Whenever I have the screen turned on, I find myself rushing to get whatever I needed to do done before the battery loses too many %, lol.

This is on Bell (Canada) with a LTE signal of 2-3 bars at home.

I hope that there is something I can do to fix this or it improves on its own. I'll do a full drain today and see what my total time is, but I have a feeling I will be lucky to get 10hr , and I really haven't started using it heavily yet. I will be pissed if it doesn't get at least 12 hr with moderate use since I work 12 hr shifts.

I guess I could improve it by shutting off LTE but that seems kind of stupid considering the LTE network was the main reason I bought this expensive phone over the cheaper ones without LTE.

I was going to buy a spare battery anyway so it will be interesting to see if the 2nd battery performs better than the one that came with it.

Have you tried adjusting your screen brightness?

Is it on Auto? Always found that not very helpful. I prefer manual control. Up when I need it up and down when I dont. I dont need autobrightness constantly using my sensors to gauge the best settings for me, using power.

Just turned off the auto setting... now have it on almost minimum brightness... I also made sure as soon as I got it that S-Voice wakeup command was off as well as the Smartstay.

My battery dropped 2% in the couple minutes it took me to wake up the phone, go into settings, and lower the brightness . Now at 90% just over 1h30 min of use, 13 min screen time .

The battery may take a few charging cycles before it starts working well.

Have had my GS3 for about a week. Using Power Saving. Have been told GPS, WiFi, Sync are battery hogs. So, turn off when not needed. Seems like doing this, I can get perhaps 2 days on a charge with reasonable calls and texts.

If I turn off sync, will I still get automatic notifications for emails and such... If not then I will probably leave it on.

Seems kind of dumb to have a "smart phone" and then have to turn off all the features that make it "smart".

The thing that kills my battery the most is the Face Book app. I could be wrong but this is how it was explained to me

Facebook on my phone shows that it uses a lot of battery power on my phone as well, its usually one of the highest on my list. But when I stream music I ONLY do it over WIFI. My numbers are with everything turned off besides data.

If I keep mine on 3G, battery life is awesome. On 4G, it's constantly switching between 3G and 4G when I'm at home or work due to being deep inside a condo or warehouse.

I think theres definitely something up with mine...

Since the last time I posted, I've been walking around with the phone in my pocket in a LTE area, I didn't get any texts, get any calls, or even use it for browsing. Only time I took the phone out was a few times to check the clock. Left the house with 80% and about 2h use. Pulled the phone out to check the time a couple hours later and its at 68% when all it had been doing was sitting in my pocket on standby.

The battery seems to be draining very fast... Its now at 40% after 7h... but only 26 min of screen use in that time, and I really haven't been doing anything with it. When I am using the phone, just browsing the internet, it seems to be draining by 1% every 2 minutes, pretty unacceptable.

Really annoying. Phone seems to be warmer than it should be too (when just on my pocket on standby).

Anyone know what the issue could be? Bad battery or phone? I already returned one GS3 (crooked screen) and it was the biggest hassle in the world dealing with my provider to replace the phone, I DON'T wanna deal with that again. I only had the crooked screen one for about 4 days and never really checked the battery on it (the wall charger was broken too so I had to charge it off the PC and never really got it to 100% cause it took forever).

I just got out of an iPhone 3GS and as much as I love these GS3s I've been having more issues in 1 week with two different phones than I did in 2 years with the 3GS. Impressed with the capabilities, not impressed with quality control.

My suggestion to people considering this phone is to make sure the store you get it from has an easy return policy because it may take a few tries before you get a good one. 0 for 2 here.

If this doesn't improve in a few days I'm going to try getting a new Samsung battery and see if that fixes it. If that doesn't work I am going to have to buy one of those awkward giant 4800mah batteries that turns the phone into a brick before I get the battery life that some of you on here are getting.

So far I haven't tried turning 4G off. I may do that over the next few days if it doesn't get better. I just hate the fact that it seems like I have to turn off all this phones selling points to get reasonable battery life.

Ok, how about this. If you are basically on your phone since you got up texting, facebooking, voxer, news apps.....in other words being tied to your phone, how long should it last. I seem to get 4-5 hrs out of it on those kinda days. My friend just got one and reported the same.
I'll have 100% in the am, mess with it for 30 mins or so then it sits in my truck for most of the day with me checking in 4-5 times and the battery is still pretty low by the time I get home at around 5 pm. It's better than my old Infuse for sure but I was kinda expecting the battery life to impress the hell out of me due to how ICS handles itself etc.

I turn wifi off while away from home and try to remember to clear the RAM every morning. I don't use battery saver mode....mainly because I assume it will monkey with my screen brightness and I hate that. Guess I could turn that on when the phone is not in use but it just feels like I shouldn't have to.

Note, I had an iphone 4 and got about the same battery life from it when I was tied to the phone.

How many of the people who are getting 13+ hrs of battery life are on LTE?

From what I've been reading it seems like a lot of the people reporting fast battery drains are on LTE networks... I will try turning that off over the next few days.

4G is a battery killer no matter what phone you get. You only have to switch it off when you're not using the phone.

Im on LTE myself and the battery life is pretty trash. Someone posted settings to disable lte and I tried it and it works but the issue is that sometimes it will drop the signal and reconnect quite often. Pretty annoying. Im about to just learn to live with it.

A friend of mine has the phone as well and I ask him how long is your battery lasting and he tells me two days, Im wayyyy more tech savy than him so I know he hasnt disabled anything and I have everything turned off and my battery still sucks.

Im not sure how often these two day people actually use their phones though, I pretty much stay on my phone at work or not. But still when I wake up in the middle of the night and take the phone off of the charger (at 100 percent) go back to sleep and wake up 3 hours later with 94 percent battery its a little annoying.

I do not have 4G in my area and I don't do Facebook. I keep the WiFi on when at home. Have a couple weather widgets going, ScoreMobile, calander and music widgets on my home screens. Yesterday in 24 hours my battery was down to 42% with about 2 1/2 hours of screen time, 10 min of calls and basic texting, email, internet ect.

For all you people having issues, it might actually help if you went into the phone settings, select battery, and tell us the top battery users (or even post a screen shot).

Mine is standby by far (which I know is a bug).

2nd biggest use is screen, but I still don't get why my phone will be dropping at least 10% an hour with under 30 min of screen use.

Will get some screenshots over the next few days.

@above 10% an hour? Yikes!

Mine usually drops at a rate of 5% per hour on standby with Wifi/GPS/4G off.
Battery life on this phone is great!! (And coming from a Razr Maxx, that's saying something!)
