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

Anyone else having this ISSUE? My last phones all had like 4-6% standby time on the battery. But this g2x has been 64-83%. If this can get fixed I think my battery will be much much better!
What can be causing this?
when you say 64-83% how many hours has it been in standby? What else is using the battery? I know the G2X in my office has like 70% standby but that's standby from 14 hours and it's still at 92% battery life. (work phone so pretty much just sitting in the office until we need it)
Standby usually drains faster if you're in an area with no cell signal from what I've noticed.

This is very important to note. As the signal gets lower, your antenna has to increase power to maintain a connection with the tower. The lower your signal, the more battery required to keep a connection
My cell standby has been alot more then my display and I don't have it in standby. What is odd. My network connection says utms yet I have 4g showing and speedtest is 4-7mb dl. I can unplug my phone leave it on for an hour loose about 15-20% battery with it like at 70%+ cell standby. It's odd...
Maybe it's the 4g cell struggling to connect?

I have the same widgets on the G2x that I have on my Nexus S. I have pure calendar and pure calendar agenda both set to update when the calendar updates. I am still leaning towards more with the 4G struggeling or something.
I've always thought umts was pure 3G while hspa was an update to that which in turn you could get the hspa+. However my connection always says umts, yet I do get way above 3mb dl on the speedtest. It always gets between 4-7mb dl.
The battery life on this android reminds me of when I had the Eris, just blah!!

I have the EXACT same issue with cell standby. I think it's the 4g connection as mine is constantly switching between 4g and 2g (never 3G)
I can't remember can you click on the "cell standby" tab in 2.2 to get additional information? It will usually say something like xx% time without signal.
yes you can click on it but that option is not showing. I was thinking just like I could my Eris was place into airplane mode take it out and it would correct the cell standby issue. But the xx% without signal is not showing. Well at least on mine it doesn't.
I don't think it ever says 3G. Mine goes from 4G to 2g. I just traveled to Indianapolis and pulled 6mb down but at home we don't have 4g yet even though it says 4g. My download at home was the same as my nexus one = 700k
So while I see it drop to 2g... I think they replaced the 3G icon with a straight 4G icon.
Plus I thought utms was edge?

Same here with the cell standby... Battery life isn't that terrible for me though (six hours down to 75 percent). Still this seems to be a big problem. Can we somehow force it to just use 3G for the time being?
Make air plane mode your best friend when your not using it. It could be widgets your using

I was having the same issue, and battery life was terrible.
Performing a full factory reset as well as completely draining the battery several times solved the issue for me.
Before the factory reset Battery Monitor was reporting heavy battery use even while idle, after the reset it only uses 2-5mA while idle compared to over 150mA before.
Today I went from 5:45 AM to 4:30 PM and am only down to 70% charge left.
same exact issue here. My usage habits have not change from my mytouch 4g which only showed a few percent of cell standy and phone idle. I dont get it, but i think that is what is killing my battery.

I'm glad it worked for you but I am a little confused as to how could this fix this problem?
I have a rooted Samsung Infuse with 1.5ROM and Defused Kernel.
Stopped the "Drm%" service and have been getting better battery life.
I have also calibrated the battery.
In home I get very good battery life on WIFI ( around 6-10% per hour drainage on Medium use).
But the moment I am out using Mobile data ( it starts to drop at 20-25% per hour) and my phone starts to overheat.
I had the bluetooth on for a little bit...turned it off but same result.
Was using Juice Defender ( the free version ).
Any suggestions.
Try the infusion 1.8 kernal and update to infused 1.5.2.
Make sure when you do this charge your battery to 100% for 10 minutes then proceeded to flash
Hope this helps

You dont need to flash when battery is at 100%, would be best to. But if not, recalibrate.

Weak signal is a battery killer.

I am in a decent enough strength area. I think it was Juice Defender, after uninstalling the app I see decent improvement and atleast no overheating issue.
So even with no widgets, a black background, mobile data and wifi off, and sync off my battery dies so fast that ill go to sleep at full charge and its dead when I wake up. And no I don't use it in my sleep. I'm running gummycharged 2.0 if that makes a difference. Any ideas or thoughts? Its a certified pre owned phone so maybe its just a shot battery ?
Sent from my SCH-I510 using XDA App
I have a similar situation. Mine drains like that at work but not at home. No amount of battery calibration, different ROMs, different SIM cards killing tasks, switching phones or anything else makes a difference. They all do the same thing. In my case, I believe it is the constant fluctuation of the actual Cell signal (not data signal) that is causing this. To see if this might be the case for you, let the phone run for a few hours where this is happening but don't let the phone die. Then go in to the "Battery Use" then select "Cell standby". If you see any percentage >0 in the "Time without signal" statistic, this may be what is causing it.
Time without signal 30%. I think you may be on to something. you might have just saved me buying a new battery, thanks friend

You are welcome. Just wish I knew what the "FIX" was. I mean, other than moving - LOL!
I have seen a small improvement by charging before I go to bed, unplugging it from the wall and leave the phone on during the night with WIFI on and no apps running.
When I do that, and wake up in the morning, the battery is still at 100% and I can get a good day with heavy use, and a day and a half with moderate use easily.
However, last night, I needed the phone to be on as I was on call for work this morning so I charged it and then unplugged. But turned WIFI off as I did not want whatsapp msgs to disturb.
No apps were running, and the signal is just as strong as always (which isn't great but is is the same as always), but when I woke up after 8 hours, the battery has completely drained overnight to an alarming 12%!!
When I looked to see what was using the battery, Cell Standby has used 39% and Phone Idle 40%, the screen was only on for 3mins during that time.
My settings for apps are that they only sync manually or when opened, so nothing was running.
When I looked at the awake time, it shows that the phone has not been awake.
So I cannot understand why by turning WIFI off, the phone will drain overnight!
In a normal day Cell Standby and Phone Idle contribute very little to the battery usage in my case, but I just can't understand what has caused this to happen.
Any help appreciated, as I am quite alarmed thinking that my battery can die overnight when it has not been used.
Thanks
I had the same problem! I left my phone at 100% and turned it off over night. And the next morning it was at 7%!!
Sooooo many problems with the sensation, I am soon change my phone.
In your pictures i can see that you have bad signal. With this bad signal the phone will try to get a better signal all the time and this uses much battery.
Try it over night at a place with better signal and look how much battery it uses. And you can charge to 100% and then wipe batterystats in recovery maybe that helps.

I have similar problem Hi friends,
I use faux123 kernel for 2 weeks + ARHD 4.1.7. All things was good, in sleep time my phone was not do any drain. I meen if the battery was fully charged it was 100% at morning (phone was set to flight mode) and even after starting the phone it was staing at 100% for one hour. And i was get 18 hours for hard working with it.
But it's 2 days it drains so fast. It drain 20% of battery in 5 hour sleep time in flight mode. And i just have 8 hour to work with my phone.

Did you install any new apps or changed some settings in an app wich can cause this drain?

Did you change the CPUFREQ? Because i think faux kernel is at 1,7GhZ after flashing it. You can use faux clock to change the Kernel settings.

I have always the same signal, it varies from 2 to 4 bar, when I took the screenshot went down to 1 but I normally have a bit more.

Bcuz with your WiFi on the phone is not switching through data signals which uses less battery. I live in a bad signal area. So calls work great but data signal is crappy, goes from 2G to 4G to 2G..so with WiFi on for data there is no need to constantly try to grab a better data signal.

But data was also turned off, and I am only on a 3G network, not 2G available with my carrier.
My point here is that when I go on hols soon I will not be using data as I will be abroad, and WIFI only once a day maybe as I will be out and about.
So from last night's performance, does that mean I will only get 8 hours??
It is weird...
I was getting some insane battery drains my self after flashing the ARHD 3.X.X the one turning the sensation to XE , allthough I had very good signal and my phone fully recharged in the morning was like 61% for uknown reasons then I jumped to ARHD 4.1.7 and since then everything is fine .I don't understand though why some people blame the phone for it.to me it appears to be more like software tweaks and twists related to battery management the sensation is amazing phone I have it for a month and honestly I never regret the day i picked it when I had to make the choice senny or sg2
