Terrible battery life, please help!

Hello I am new to this forum, I just got the Samsung galaxy s 4g this Wednesday and I was wondering if anyone else was having battery issues. Right now I have my phone set to minimum brightness, auto sync off, black bckground and juice defender on. So I don't understand why am I getting only about 3 hours of battery life when all I'm doing most of the time is surfing the web(this forum) and facebook. I even get better battery life from my dads vibrant which is completely stock, has auto sync on, no juice defender, and screen brightness set to 50%. From reading the stats of both phones, the vibrant 4g is supposed to have a slightly better battery. I also don't understand why if the screen is at the minimum it still takes up 94% of the battery whereas on my dads vibrant 50% screen brightness takes up 30%. Is there anything I can do? Will wiping the battery stats help? If so how do I do that from a stock unrooted vibrant?

Check your notifications settings. I know that Samsung's contacts integration with social networks takes a big toll on the battery, hence why I've disabled it. Also, disable T-Mobile's Contact Backup Sync, just use Google's contacts integration.

Thanks for helping, but yeah I have those disabled already.

No, I charged mine this morning at 630AM, and I have been playing with it all day. It is currently 610PM, and I am at 60% still. Seems pretty good to me.

Wow thats much better than what I have been getting, have you changed any settings that might have increased the battery life for your phone?

Does the trick to fully discharge and recharge 3 times work with these batteries? According the the Li-on technology this is not supposed to be necessary but I've heard stories in the forums of folks getting great battery life on other phones after doing this. Many people also say their batteries work a lot better after a week of use (supposedly after "training" them as well.)
I believe the G2 is clocked down for this reason. You could try CPU-set app, clocking down to 500-800mhz when not gaming.
Anyone tried these tricks?

Will ill try to cycle charge the vibrant and use it for a week, and ill try out cpu set. if this doesn't improve I'm definitely returning this phone. I had soo much expectation for this because I have seen people getting up to 24 hours. I can't even get halfway through the day barely using the phone.

Im having the same issue with battery life.. for me its a deal breaker.. I use my phone pretty heavily for keeping up with email and a little web browsing as well as talking quite a bit.. My iPhone 3Gs lasted me all day of heavy use and with the SGS4G I have to charge the damn thing at least once a day with light usage and if I have to be on the phone a lot then its twice a day.. Not acceptable at all...
Thats with wifi and gps disabled..
On the 3Gs I had wifi, bluetooth and the gps running all the damn time...

Took my phone off charge at 6:30 this morning haven't put it on charge yet at 88% never had this much juice with the nexus one.

I'm not having any issues with battery life or heating. I use wifi teather most of the day and I'm getting to use it all day without issue. I did cycle my battery 4 times already just in case it matters. FYI

The batteries that our phone uses DOES NOT require u to cycle the battery. In fact, doing so will harm your battery. To avoid damage to your battery always charge ur phone when u r at <15% battery level. Trust me I thought the same until I did the research. I will post more info when I get on my PC later.

I just bought a Galaxy S 4G on wednesday. First android device coming from iphone 3G. I'm still trying to figure out the best way to preserve the battery life.
I took it off the charger at 6:30am and the battery was at about 2% at 8:30pm.
I haven't rooted the phone yet to remove some of the bloatware that comes pre-installed.
I've got email accounts synching, brightness set at about 10% w/ a static wallpaper. Played about an hour of angrybirds throughout the day and didn't really do any web browsing with a few phones calls. I mean 14 hours is decent but from what I've read there are plenty of people getting a full day of use and still have 50% battery left.
I guess once the battery fully charges I'll put inception on, turn off syncing and try a few other things.
So I guess I said all that to say this, my battery life isn't great but it's not downright horrible either. Any suggestions would be much appreciated.
And yes I'll continue browsing all the forums to see what else I can find.
Edit:
Played through half of Inception in airplane mode, brightness at minimum. I dropped from 93% to 80% in an hour and a half. Not too shabby.
Also created a shortcut to toggle between 4G modes and Edge. I know 4G is going to be a pretty big drain so I'll see how much that helps.
I'll keep tweaking it.

this is completely true and if you read the manual on page 13- h t t p:// downloadcenter . samsung . com/content/UM/201102/20110224044646930/T959_Galaxy_S_4G_English_User_Manual.pdf it says that
"• Do not wait until your battery is completely depleted before charging
your device. Repeating this process of a complete discharge and
recharge can over time reduce the storage capacity of any battery."
right now my phone is at 23% battery level with up time of 46:46:40 hrs/mins/secs. with skype calling (around 10 minutes), text messaging, browsing the net (for around 5 minutes about 6 times a day), and talking on the phone (around 15 minutes)
the settings i did:
1. took a picture with my finger blocking the camera to get pitch black picture and set that as my background and deleted all the shortcut icons (i short, i only have a blank screen with the only 4 icons down below)
2. changed the brightness settings to 2 clicks to the right from 0% brightness (or you can lower your brightness all the way down during the night, and 2 clicks away during the day, this will save you more)
3. disabled haptic feedbacks and audible touchtones, selections, and screen lock sounds
4. disabled animations
5. disabled background data and syncing when not in use
6. disabled packet data (3g), wifi, and gps when not in use
the last two are the biggest settings that made my battery last longer.
7. i only charge my phone when it gets to 20% and the manual recommends not to use the phone while charging
i hope this helps.
and yes it is recommended to charge your battery to 100% before you turn on your phone for the first time and this is also stated on the manual.
one more thing, don't forget to set your browser's brightness setting as well

Horrible battery life Verizon model

After 7 hours, I'm at 14%. Screen was on for 2 hours and I haven't been doing anything intensive (3d games or movies etc) just some web browsing. On automatic brightness. Are other people getting battery life this bad?

what about gps, nfc, app update intervals, there can be a lot going on in the background.

to be fair, my gf's verizon GS3 is ridiculously efficient. granted she was on wifi most of the day and doesn't use internet as much, but she was at 53% with 13 hours and 2 hours 14 min of screen time.
my att on the other hand, wifi off and on LTE, was at 53% with 6 hours and 2 hours of screen time.

How is the LTE signal in your area, if its not strong and swapping back and forth from 3g to LTE all day it can take a huge toll on your battery.

Try it without wifi and 4g. ONLY use 3g. I have a theory...

Mine seems to be doing great. The signal isn't that great in my house either. This is more real time use as I was asleep for a while. But when I woke up at 10am this morning it was at 92. I've been using it moderately ever since. I get about 8 hours with ridiculous use(4+hr screen on time).
Never on wifi.
Edit: I realize its kind of a bad example since it was in standby more than awake. But I'm getting great battery.

Screenshots for those of you wondering

I had the same problem as you did. What made a significant change for me was changing amount of apps to keep running at 4 instead of default. Also I found the xda app runs in the background, continues to drain the battery. I have to manually kill the xda app every time I exit it. For today I'm at 12 hour running, and screen on 1.5hrs and 59 percent battery life.

I've been getting worse battery on wifi than 4g for some reason. I also noticed my idle power usage is around 115mA, where on my thunderbolt it was around 20mA

Ditto on the xda app, it was burning up cpu cycles while in the background, enough to make my phone warm. So I just close it every time I'm done using it.

Woh how are you getting your current draw? The apps that I've tried won't support the s3.

I have the Verizon model of the S3 as well. I have had it for over a week now because I was an early pre-order so I got it really early. For the first few days I was getting really bad battery life. I would maybe only get 8 - 9 hours with moderate usage, that being about 2 hours of screen time. I would play no games, and just browse the web and text. I am a big texter though, but on my DINC as long as I had mobile data switched off I could get plenty of life out of my phone. With this phone for some reason after about 70 percent, mine will start to drain much faster regardless of what I am using it for, even if the screen is is off. Just to test it I left all the radios on while the phone was at 100 percent over night, and the next morning it was at 96. The next day I tried the same test when my phone was at 50 percent battery, and when I woke up it was at 10 . I don't really understand what is going on here either. I keep seeing all of the reviews for the device even the Verizon version to point towards great battery life, but I am just not seeing it. Maybe rooting and a re-flashing the stock rom plus removing bloatware will help. I also got another battery just to see if that was the problem, but it doesn't seem to be. I'm hoping this is just a software issue, because I don't know why some can get such great battery and some can't. I would also hate to have to get a replacement phone.

im getting around 10 hours with Heavy use ... 6 hours of pandora, youtube, email, facebook, twitter, web
On day 6 with the phone

[Q] Batt life

Am I the only one who doesn't get 4 hours of screen time from a charge? I've seen many posts about it, and I average about 2. This is on aosp/touchwiz and many different kernel combos.

I don't typically get 4. I get about 3 or less. And I don't overclock like most do. It all depends on what you use your phone for , how good your service is, phone calls/ texting you do. I listen to music every day which hurts my amount of screen time, and I don't get very good service most of the day, which also hurts it. I have noticed that installing JuiceDefender dramatically helps so my battery drains much slower when I'm not on it by turning off wifi/4g after a few seconds, and back on at intervals to sync. CPU Sleeper is also a noticeable gain after you install it. It shuts off the extra core or something when you don't need it.

On a regular basis, I've only gotten around 2-3 hours of screen time from a full charge.
I've used stock, CleanROM, and SynergyROM
All the same.

There are SO many variables that can contribute to lower battery life. Screen brightness, constant device wakes, account sync, application efficiency, etc. I normally get 3 hours of screen time because I keep my sceeen at half brightness and I wake my device up a lot throughout the day. I'm willing to bet I would get 4 hours if I reduced the amount of device wakes. But who knows.

Yeah I understand wake locks and such I just thought I was getting abnormal battery life. Maybe not. I only lost 10% after sleeping in for 12 hours. Medical classes haha. But my screen time seemed low. Oh well, I carry a charger everywhere

Why do Android battery life suck?

So far, I've owned 3 Android phone, and all of their battery sucked. I owned an Evo 4g, HTC Rezound, and I had 2 Galaxy S3's. Even with Extened battery, the battery won't last as long as an iPhone. And it doesn't stop here. It takes FOREVER to fully charge the battery only to find out that it gets depleted super fast. On the S3, I would be at 20% at the end of the school day, but with an iPhone, I end up around 60% with the same amount of use. The phones go up 1% after 5 minutes when plugged into a computer, and its annoying. I love Android with all my heart, but I can't deal with this problem. Anyone know of phone that has really good battery life (besides the MAXX)?

An iPhone's battery life is roughly the same in each iteration as a device from the Galaxy series. In fact it's been tested and the Galaxy S III lasted 6 hours and 55 minutes compared to the iPhone 5 which lasted 7 hours and 13 minutes. Both OS's implement battery management very well, and at the end of the day battery life is mainly dependent on user use. You can't expect an Android device to have numerous data hogging widgets as well as numerous background processes active, all while surfing the web with multiple windows open, and not drain just a little quicker than an iOS device that doesn't even utilize true multitasking. Please.
Also: It doesn't last as long as an iPhone "even with an extended battery?" GTFOH. Either your iPhone runs on nuclear material or you're full of sh**.

Why don't you use something like BetterBatteryStats and find out why the battery is being used ?
I get 3-4 hours of screen on time on my S3 with stock battery and kernel, but with some minimal battery-saving settings.
It used to be a lot worse - but I actually investigated and found out what was eating up the battery. I guess I could have just complained about it, but it was a lot faster to just work on finding a solution. I've been really impressed with how long my battery has been lasting lately - and it didn't take all that long to just read the BBS report and make changes.

In my words, its actually depend on your uses. Now a days we have 4"- 5" screen, where lots of processes are running in background. Using Dual Led Flash light for camera & having lots of Games,applications & files. We were used to have phone like NOKIA & BB. Where we just clicked over a button & thats all. But now when You click on screen, whole screen has to be work.
But yes, Few companies has taken it hard & Provided battery like MOTO MAXX.. also few have kernel bugs. So, it totally depend on you buddy, how you take it. Use data connectivity less & check whether your phone is going to Deep sleep / other name as per phone is going or not.

Be realistic with the brightness, keep it on auto don't run it at 100%. Try different ROMs with tweaks. Adjust settings with kernels for a faster battery recharge. Your options are infinte. Maybe android isn't for you.

There's an official Google statement that wiping batterie stats won't improve your battery life.
Wiping the stats forces android to recalibrate and calculate the battery stats.

Do you mean the time for one or both batteries ?
I get 3-4 on stock battery - but I always have my screen on the lowest brightness - and sometimes lower (using the Screen Filter app). I'm inside most of the time, so I don't need a very bright screen.
The only time I really lose battery like crazy is if I'm playing Ingress - because then I need to turn the brightness up and GPS is constantly updating so it's not exactly unexpected.

I never seem to have issues with my galaxy s3. You might want to get a battery management ap to see where all your battery is going towards. Or you might just be a heavy phone user and in that case, it wouldn't be the phone's issue...

Post your battery stats screenshots here!

Ok, I have to admit, I'm not the biggest fan of this phone so far (way too much bloatware, and a little laggy, IMO). But the battery life is effing fabulous. 5.5 hours screen on time with nearly 20 hours screen on time. AND THAT IS ON LTE THE ENTIRE TIME -- WIFI WAS NOT USED AT ALL.
Don't ask me why my "mobile network signal" bar has some black gaps on it. I was not in airplane mode at all and as far as I know I had a full LTE connection the entire time the phone was on.
I don't think I've ever seen 5.5 hours screen-on time on LTE on a stock ROM/kernel before, so I'm pretty impressed.
Info: Brightness manually set to ~25%. This was mostly browsing the web and xda, and using messaging. There was a short call and about 30 minutes of GPS navigation. One Gmail account syncing the entire time. Solid black wallpaper. Most of Samsung's gimmicky features disabled, and most of Samsung & AT&T bloat disabled (see my HOLY MOTHER OF BLOATWARE thread for full list).

One Gmail account syncing the entire time. Solid black wallpaper. Most of Samsung's gimmicky features disabled, and most of Samsung & AT&T bloat disabled (see my HOLY MOTHER OF BLOATWARE thread for full list).

I have turned off animations. Any downside to forcing gpu rendering?

So what is the technique you will be using to cycle your battery? Charge for 8 hrs before powering on. Then drain until it shuts off by itself. Or until it reaches 1-5%? Then power off and full charge? And how many cycles do you normally do? About 3 or?

Or you can just use your device normally as I don't think the battery has a memory.

Dont want to be a negative nancy here.....but given that the screen eats most of the battery, I was hoping for more at 25% brightness. I had the One for a few days, and it was set to auto brightness most of the time (which was pretty generous with the backlight, seemed to hover around 40% indoors except in total darkness, and maxing out outdoors) and it lasted me 5 hours on LTE.

Yeah I am not impressed with the battery figures considering the battery size...
Although that extra 200MHz of clock speed certainly can factor into that and nobody has really dove into what device-specific CPU optimizations each device has.

Fantastic. Nice job Sammy. Looks like respectable battery life!

Went on 16 hours yesterday so thats pretty good!

I made it 1d 1h 50m with 5 hour screen on time (50% brightness manually set) Wifi was on the entire time, mobile data was disabled and gps was on from time to time (10 hours straight at one point) It handled pretty well for its first day, got the phone set up during that time. 1% Life atm

It has a 1080p Super "Power Sucking" Amoled screen, so 5 hours of screen on time is quite good in my opinion.

Impressed myself so far...

Im really happy...watched over an hour of youtube (music festival videos) listened to over 2 hours of music...and general messing around...with everything on default settings...turned nothing off when I got the phone, and have nit uninstalled any bloatware yet...so this is with wifi on, lte on, gps on and whatever other s features are on by default and auto brightness I believe

Can someone please post the screen that shows the mobile indicator bar? I want to know if I'm the only one getting black gaps.

I could only go with about 3 and a half hours of screen time on my SIII so 5 hours is definitely very good!
