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

Battery life? SetCPU?

How has battery been for everyone? Mine has been atrocious! I just formatted the phone and am leaving it "naked" overnight to see how it fairs. Also, has anyone successfully used SetCPU?

Battery life has been terrible, even sitting idle with the screen off it uses 1-2% battery in just 10-15 minutes.
Turned off bluetooth, gps and all syncing and it still drains battery just as fast.
About to factory reset to see if it helps....that is if I can get that far without it freezing and restarting itself.

My battery has been great. I took off charger at 8:30am and at 8:02pm its at 61 percent. Thats with some texting, web browsing and wifi.

It will get better guys just let the battery get conditioned. In the next couple charges it will start getting better. Don't panic you just got the phone, give it a few days.

Yup I left work at around 5pm with it charged 100% and by 9:30 I had hit yellow(20% -ish). To be fair I was using it quite a bit messing with settings and stuff, and its brand new.
My G2 battery would last forever, literally off the charger at 7:45am and by 3 or 4pm it would hit 60%. This phone is worth it though, IMO.

I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Juice defender helps tremendously. Give the app a try. Also, let the battery settles by fully charge it.

Yesterday was my first full day, but it gave me plenty of use. I unplugged at 10am and it lasted until about 6pm. Keep in mind I was playing a little and screen was on most of the day cause I was setting things to my liking.

I agree with you, I only use Juice Defender Data Toogle though. It works great when I don't want to use my phone data.

Battery prob is now worse!

I'm rooted first of all.
Well, wifi, all GPS, and bluetooth off.
my battery was okay, it lasted for a day mostly. and I think about 2 days ago, the battery suddenly getting worse. Everything remains same. I haven't changed any option, but the bettry is suddenly worse.
I don't use my phone that much. like I got a phone call yesterday and today? no texting, no internet, no app uses.
I charged my battery full(til 11am or til noon), then it dies before 5pm.
(Today I charged my phone til 9:40am, got only one single phone call lasted 1-2mins, and my battery is already 47%.)
It's just terrible! Anyone has same prob????
I'm in California BTW.

are you rooted?
what rom/kernel?

I'm rooted and I think it's stock rom.
I just followed the manual perm root process.
It's weird because under same conditions, battery got totally worse than before. It lasted at least for a day, but now, it lasts only 4-5 hrs with same amount of usage under same conditions.

ever figure this out?

Just rooting will not change anything to your battery life. You need to install a rom or a different kernel in order for it to change anything.

Mine too has gotten worse in the last week. I am not rooted. At this point my battery is draining roughly 25% per hour with little or no use. Spare parts shows the most usage on my phone is 0. I have tried getting rid of weather bug, Pandora and sirius. I tried looking for something to explain exactly why 0 takes up 10x more battery than Android system itself and I have came to the conclusion that I am lost. Any direction to the correct forum topic would be appreciated.

Have you tried the "Blockbuster" mod?
1) open the Blockbuster Application, it should ask you to update.
2) once the update has finished open the application back up and
3) navigate to Menu>Settings> "Disable Movie Updates"
Users have reported better battery life.

Thanks for the reply. Yes I have updated and disabled the Blockbuster app. Better yet even I just rebooted my phone and it drained 12% on the battery. How is that possible. I am using my stock battery now and not the extended, so the % would be different with the stock compared to my extended but really I don't think it should use 12% on a reboot.

I guess you and I are on the same page! I charged mine til 9:40 am and went to work yesterday. I got only one phone call that lasted 1-2mins. The battery was already 52%. All GPS was off, bluetooth off, Wifi off, everything off except 4G. I sent a text and received a text, and the battery drained to 46%. After a few mins with no use of the phone, the battery warning sound played. So I had to charge my phone at that point. It is just totally weird. Under same condition and same usage of the phone, the battery lasted for a day at least. (4G was on at the point.) I don't know what cause this problem. Anyways, I just unrooted mine and got a software update via OTA. I don't know if this will fix the problem. Any luck to you yet?

I am going to charge tonight and try current settings tomorrow and see how long battery last. It is to the point if I have to turn all this stuff off, doesn't it defeat the purpose of having a smartphone?

Try ZD Box
Try ZD Box, and use its task killer to stop any programs your not using right then. Pandora is another app that loves to stay on and chew at your battery...

My phone just started doing this as well. I've been using the TBolt for a couple of weeks now.
Just yesterday my battery life took a serious nose dive. I've adjusted all the settings I can and the battery is dropping like a drunk girl's panties...
I'm having to charge it all the time now just to keep it from giving me the low battery warning.

Ok well here it goes . Off charger for 30 mins 7 text ,this post and a restart and down 10% already. Wtf

That's about what mine took on average to reboot. 10-12%.

I'm at 72% after 11 hours of idle usage and that's on the 2750mah extended battery. That would put me at 46% after 12 hours having not touched the phone once. I literally fell asleep as I took it off the charger...
Something is jacked up and I don't know what.
Rooted, Virus ROM B3, 1.8G kernel (forget which).

I've gone to Imoseyon's Sense lean kernel, special edition.
We'll see how that goes...?

Wanted to report back as I think the culprit may be the wireless tether app.
I turned GPS, WiFi and all my sync's back on and the phone is back to giving me decent battery life.
I did some changes with the tether app and I'll report back to see if my suspicions are correct.

Infuse vs atrix battery life

I was wondering if anyone had a good comparison between the two phones.? I currently have the atrix and I have been seriously thinking about switching to the infuse but I don't know if it will last as long. I am currently getting about a day out of the atrix and I can't afford to go to a phone that will last any less.

The infuse battery lasts just as long. I had an atrix and was impressed and am equally impressed with the infuse.
I go at the very minimum at least a day, and on most days well over a day. Under normal circumstances I charge every other night.

Have you done anything to increase your battery life? I come from ios and I am a firm believer in not having to constantly turn things on and off. I will not shut off my data or modify sync schedules and my corporate email must be on push all the time. I also don't use a task killer. I was just wondering because you said at minimum a day and that is my maximum.

I had the Atrix for about 20 days. I loved the battery on it!! That phone would last me a whole day! I left gps and sync always on and I had brightness on max with screen timeout at 2 minutes. I had issues with it and definitely didn't like the cameras so I returned it.
The Infuse I've had 3 or 4 days now and the battery has gotten better with time. I have the gps and sync always on and brightness at a bit more than half. Doesn't seem to last me as long as the Atrix did, but it's much better than the Captivate! I'm having data issues with it though just like I did with the Atrix

I had the atrix for 30 days and so far the infuse lasts just as long on the battery. Atleast for my usage.

I'm sorry if this is a silly question but how does push save battery?
I was under the impression that push required the phone to be constantly checking for new emails or to have a connection active at all times. Both of the scenarios would lead me to think that it uses more battery than setting a fetch schedule.

For refernce here is what an average day for me is:
3h 25m since unplugged
voice calls 77% 1h 33m
display 9% 39m 13s
phone idle 4% 2h 46m
android system 4%
CPU total 5m 29s​cell standy 2% 3h 25m
touchdown 2%
CPU total 2m 38s​android OS 2%
CPU total 1m 52s​
With all of this I am at 50 and it has only been 3.5 hours of a 10 hour work day not to mention time during break and when I get off.

This guy here says that he was still at 62% battery left AFTER FOUR DAYS
http://www.youtube.com/watch?v=TXyRG0S3o3o
forward to the 1:45 mark to hear him say it...
Maybe the Samsung sends out test models with better batteries to the websites doing reviews so that potential customers think it has better battery life than it really is and purchase it???

Pull is when the phone checks the server every X minutes for new messages, whether they're there or not.
Push is when the server sends the new message to your phone when it gets it.
Depending on how many messages you get, Push can save some battery.

Battery

How much battery do you guys usually get? Recently I've noticed a large drainage of battery and I know phone isn't too good with battery but even this doesn't seem normal. Some of my apps use 1-2% of battery per minute! Is this normal or not?
Sent from my SGH-T769 using xda app-developers app

Oh and my battery never gets to 100%, the phone will tell me it has reached 100% but as soon as I unplug it, the battery is usually at 92-95%, also I use Juice Defender and it seems to help but not much..

generally my phone will last all day, but that is only when i rarely use it. when im using it a lot, for example if im playing games and listening to music, it lasts about half a day. but it all depends on how you use it. if you are using a lot of 3D apps, your battery will drain quickly

Mine lasts all day. I listen to local music and have push email hitting me most of the day. I might have to charge it at night if I use it a lot and I am up past midnight.

I think the Blaze battery is one of the best I've seen. I use my phone lots from 8am till 23:00 and it gets down to about 5%.
That's on Dark Knight ROM.

Odd ive got over a day on my battery with over 4 hours display time on my blaze with erikkm's darkknight rom with moderate use Lithium ion batteries have a memory and when you fully kill the battery it reduces its memory slightly, always always try to charge your phone before 30-20% and dont unplug your phone while its charging that can effect the battery memory as well.
