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.

I got my replacement 4g today. Hopefully ill have better results. I have a question for those of you that are getting really good battery life, are you running juice defender or something similar in the background? Maybe that's a factor in why I've been getting terrible battery.

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

Need a good answer on my battery:

I've been debating on whether or not to go get my Galaxy S III replaced at Best Buy because of the sub-par battery life I've been getting. On average I get about 10 hours of battery life even with low usage. I keep autosync/bluetooth/gps turned off, and have screen brightness set to auto. At any given time of the day (I work from home) I have anywhere from 0 bars to 3 bars (crappy signal at my house). I'm thinking that my cell radio is what's draining the battery mostly due to low signal strength. I was wondering what you guys thought.
Also I did run CPU Spy for a few days and my phone was going into deep sleep when I wasn't using the phone.

How much screen time are you getting? I have some screenshots of nearly the same amount of time on battery as yours. I had 4 hours 20 min of screen time which I think is great!

I would start with option 1.
Option 1: If the phone works well besides battery life then see if they can just exchange the battery at Best Buy.
Option 2: Exchange it for a different phone through Best Buy if your under the 14 day period.
Option 3: Buy a good cheap battery off ebay, either an Anker or Hyperion battery. They both work well and I have used both. No NFC chip though.
Option 4: Buy a new samsung battery.

Only two hours, light - moderate use... I would say try and get a new battery. Factory reset could help but from the screen shots looks like it's sleeping fine. I would go with ^ that guys ^ ideas.
Btw I also have poor signal were I'm at for the summer, so I wouldn't think the radio is to blame.

Damn. That picture was right after a factory reset . I'll go exchange it then .

My girlfriend and I both have noticed the battery life gets WAY better after using the phone for about a week or less. I think it has to do with the battery cache and the phone calibrating itself. DONT wipe the battery cache like most people recommend, itll just restart the whole process.

It's the best battery saver I have tried.

Hi all,
Just want to share a battery saver app which works really well on my charge. I used to have 10-12 hrs normal usage, now I have 20hrs with left over at the end of the day. The only feature that you have to look out for is "enable cpu saving", it may work for you, but for me this put my phone in so deep sleep that it never wake up. But of course just pull battery, reboot then disabled the feature. it made by a big Chinese internet security company and "melvinchng" is nice enough to translate it to English for us. All credits go to him. Hope you all like it. Cheers!

For me it is, but the best bet is try it for yourself and let us know your opinion. You have nothing to lose.

Here is screen shots of mine. I will post a few more later.

If u want to save battery just turn off 4g under wireless and networks. My 3g only will last 1.5 days of moderate to lighter use.

I may be missing something, but it looks like all it is doing is blocking mobile data periodically, right? mobile data is the biggest drainer on battery performance (in my experience). however, I don't want to have it off, even for a minute - as if I misplace my phone, I'll need mobile data to be on in order to find my phone via the Lookout app...

It doesn't unless you instruct it to do so. If you toggle wifi/4g on only when needed then you should save even more. Did you see Vulkano? that video streaming over 4g. If I have wifi/4g on all the time, with my normal usage, I can have the phone unplugged at 8am to 10pm and still have about 30% left. Of course my normal usage maybe different from yours. If I have your phone in standby (screen off), I got 10hrs and the phone is at 91%.(about 1% per hrs). I suggest to find out if this app really help or not, just try it out, you have nothing to loose.

thanks, I will.
I know that in standby mode with wifi on and 4G off, my battery drains about 1% per hour. with 4G on (no wifi connection), ~5% per hour.
once factoring in some moderate usage, that drops down quite significantly.

OK, as promissed, here are pictures after 11hrs. Noticed my screen time is more than 50%.

Looks good. But will need to see a comparison to without the app.
But I did download and install it. Will see how we do tomorrow.

Actually, you didn't include your screen on time at all. Your screen's percentage of battery use was over 50%, though. Including your actual screen on time would help when comparing battery usage.

well, this app was a major fail for me. after 4 hours, down to 61%. it blocks what I need (google syncs such as mail, calendar, photos, drive, music, etc). so if someone sends me an appointment, I will not receive it.

I don't have any problem with Juice defender. But I guess it isn't for everyone. I just use it so I don't have to worry about manually switching back and forth between 4g and wifi as I go around throughout the day.
I turned off 4g recently to try to improve my horrible battery life (just got 4g in my area too ). It wasn't a huge difference but what really changed it for me was to stop overclocking. I really don't see much lag anyways and it didn't help with the apps I wanted so fixes fine for me.

regarding Wifi, I have found that editing the build.prop file to adjust the wifi interval scan helps dramatically. I changed my 1800 (once every 30 minutes). now I leave wifi and 4G on all the time with no significant battery drainage.
but I have found that these so-called battery saving apps just simply cut off mobile data or "auto-sync".

This app was a huge fail for me. Back to the antutu battery saver i go.

antutu was a fail for me too. so was "easy battery saver"
trying out juice defender again. I think I'm okay with mobile data turning on/off periodically. JD seems to do this nicely. I also like how JD turns on mobile data when the screen is unlocked.
however, I'm thinking that this could be done via a build.prop edit of some kind. essentially, what I would like to do is:
if WiFi is disconnected and screen is off/locked, turn on mobile data for 1 minute every 30 minutes, if WiFi is connected, turn off mobile data and keep wifi connection.

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).

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?

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

[Q] Need a new battery?

Hey guys, i'm wondering what kind of battery life you guys are getting because my droid x is currently getting better battery than my s3.
On Wi-Fi I drain 10% every half hour of screen on time. I should be able to max at about 5 hours screen on time, however the best I've gotten was on 4 hours, on a good day. So I'm just wondering what the norm is for our phones. Thanks guys

3.5-4.5 hours of screen on when all on wifi is normal. 2.5-3.5 screen on time is about normal for LTE. I'd say these are normal screen on stats given the display size, user set brightness, and AMOLED's poor performance with bright colors compared to dark colors. Dark color screens require less light. Bright colors (browser, wallpapers) draw more power from AMOLED displays. I usually get 3-4 hours of screen on time with my display brightness at about 50%.

Thanks for your response. I forgot to mention that I always have brightness really low. You claim to be able to get about 4hrs screen on at half brightness. I'm going to try setting my brightness and see where I end up. Right now I'm at 60% with 1hr 45m screen on, WiFi, minimum brightness. I could max at 4 hours in theory with the lowest brightness. I think my battery is starting to go.

There is always the possibility that the battery is going bad, but your battery stats aren't that unusual in my eyes. I've been thinking of getting a newer battery as well just cuz I've had this one since release date. Seeing if there would be any improvement.

Try a free app called RootDim. Let's you set lower but still very viewable brightness settings. I think most days I set at 25% but the nice thing is the brightness control is a slider so you have more control. Plus you can set profiles.

I have never had a phone long enough to have to buy a new battery. What's the average life of one?

That is what I am trying to find out, no one seems to own a brand new battery lol. Im still debating whether to buy a new battery.

My own experience
since 1 year I'm using the Zero Lemon Battery 7500 mAh
Have unlimited Data Plan with Verizon - Wifi Tether to my laptop for 10 hours a day
Phones heats up a bit. But, giving me, excellent service.
The main reason, I ditched Apple is because of the extended battery
Not even the so called dedicated Jetpacks don't run that long.
I use everything - Full brightness - High Volume - Vibration - listen to songs - play games very rarely though - may be 30 min. in a week or 10 days.
I PUT FULL CHARGE THROUGHOUT THE NIGHT. IT WILL BE 100% CHARGED by 7:00 A.M.
As I have said, I have been using this for the past 1 year. Still going Strong.
This is the main reason, I'm not upgrading my SGS3.

Well, aside from the reason it's still a highly capable phone and doesn't lack anything of importance over the newer models in my opinion. In fact I have a S4 and my mother's S3 is currently much faster than mine was before the fine dev's around here got their hands on it. Now they are dead even and most apps run identically on both.
Currently trying to figure out why hers won't charge. I have put a charged battery in there and that works fine but it won't charge in her phone. Guess I just gotta take 'er apart and see if there's a bad solder point or broken pins somewhere. This doesn't seem to be a common issue.

Might be a bad charging port. My fiancee had to get a replacement S3 from VZW recently because of this. But I'm no expert on taking it apart but if you successfully figure it out that way then kudos to you

We'll see. I'll give it a shot when I get a free second and let ya know how it goes. It's out of warranty so there's no way I can screw it up any worse.
