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

So ever since I first bought the G2x, I've always had juice defender a part of it. Now having done a factory reset, since May (when I got the phone) and not installing juice defender, it seems that I get the same if not better battery life without juice defender installed. Could juice defender just be adding to the battery drainage also?
Yea, I am in the same camp. Juice Defender really has done nothing way too much tweaking it. I have to say its like all of the purge from memory apps...you mileage might vary, but for me they aren't really helpful.
It seems to me that juice defender might be good for over-night, or for situations when I'm not going to be checking my phone for hours. Otherwise, the radio keeps getting turned on and off...on and off...everytime I wake the screen to text or something...that's in addition, of course, to the regularly scheduled times that it does it on its own.
But then again, instead of having it running all the time, I could probably get the same effect if I just went to airplane mode overnight.
Interesting point, OP...and gave me something to think about.
I'm gonna test that today, yesterday I got 15 hours with it on and set CPU profiles today ill turn off juice defender ultimate, ill keep u guys updated.

Yeah, I tested this week. Ifound no noticeable impact of juice except maybe overnight. During the day, and no impact, and perhaps even a negative impact.
I just manually toggle data off at night anyway.
There is really no reason to ever use juice defender when Tasker exists. It can do everything JD does and SO much more.
After testing pretty much every setting I could think of, the only things that made a significant difference is disabling data and GPS. I set up a screen off = data off, screen on = data on set and battery life WAS improved. However, I use Google Voice for all my texting, so I had to have some data, so I tried the same thing but reducing to just 2g and no improvement was noticed.
Keeping GPS off permanently but allowing it to run specifically on applications that need it helps too. Note that this is not possible on gingerbread except for CM7 and ROMs built off of CM's source. I imagine toggling bluetooth and/or WiFi would influence things too, but I never use either. No other setting resulted in a significant improvement in battery life.
Note that during all of these tests, I kept screen brightness to 18%, toggling to 25% when in direct sunlight and 0% in the dark. As for airplane mode at night; I plug the phone in at night and unplug when I wake up so this is a nonissue for me but AM is the best you will ever see your battery life without using things that require root.
And, of course, underclocking to minimum when screen is off improves more than everything else combined. Kernels and clock speeds matter far more than things like GPS or data connection.
Well I'm through testing today I got 11hrs and 18 min without juice defender compared to 15hr with it yesterday, and I used my phone less today, so juice defender gave me about 4 more hours, tomorrow I'm gonna use juice defender and 2g.

Oddly enough, the free version seemed to work better that the paid version. A lot of the time wifi and 4G will stay on even when not using the phone, and I have to manually turn off/on wifi depending on the situation. As stated, it does help when not using your phone for a while, but I'm no pro at it or anything, could be the settings.
This rom used to be fine, now it is draining extrememly fast and I don't know why.
I am on Gingerbread KF2 and really haven't done anything else yet. I used to be able to make it through an average day of ~15 or so hours using the phone only for some messages, a call or two, and a few minutes of music. After this type of usage, the battery would be around 70-80% at the lowest usually. This is even with the screen at FULL brightness all day.
About a week ago, it started draining super fast. The same usage runs the phone down to about 20-30%, which is ridiculous. In battery stats, Android OS is always FAR above everything else with like 60%. A couple battery calibrations did nothing. I don't use task killers, but I do check my running apps. OS monitor didn't help me at all, and checking my currently running apps just showed mostly system apps that should not be draining hardly any battery at all.
Any suggestions? I think that about covers it all. This just has me stumped...
go through your apps and see how often they check for updates. there were a lot of updates recently and some settings may have changed. If nothing changed, can you do a quick scan with look out? Just to be safe. Also, try juice defender and set it to aggressive
Sent from my SGH-T959V using XDA Premium App
Lookout didn't pick up anything and I set JuiceDefender to aggressive. Will JuiceDefender warn me of an app using excessive battery?
Nope, that battery is still dropping like crazy. (8% in half an hour from almost no use.)
Maybe I just need to reflash and start over fresh...
It will take a day out two to settle in. is your phone sleeping properly when the screen in off? Press the volume keys once it locks and if it makes the sound then it if still on.

Sleeping just fine.
Yea, I guess if you can't figure it out, you can reflash. That is a pain though. I would say to try out jd for a while longer and see if you get results. fb us usually the culprit for my battery drains, but if you checked all of your apps and changed them to manual, then there isn't much more you can do.try putting your screen to auto brightness

So either juice defender is helping or ADW launcher was using excesive battery. It is working better today after I switched back to launcher pro, but still going down pretty fast.
Sent from my SGH-T959V using XDA App
ADW doesn't really drain much battery for me. It actually uses less RAM compared to LauncherPro and Go Launcher (for me).
I think you should just try reflashing your ROM, maybe flashing the new GB ROMs too.
Also, are you sure you're doing the battery calibrations properly? That might also be an issue.
Maybe it's not your phone or ROM...
I've had several ROMs in the last few weeks and have noticed this behavior on many of them....after searching, I found this.
T-Mobile has apparently noticed some abnormal battery issues in areas with their "4G" HSPA+. They're asking people in their support forum for a bit of info to help them find the issue.
support[dot]t-mobile[dot]com /thread/3544
The problem was initially believed to be affecting the G2 only, but is now believed to be affecting all phones in their "4G" footprint that started when they updated their towers in late July. The update provides the government an emergency channel to use, but it appears that it may be causing network issues.
Thanks for bringing it up, this is affecting me too. i lose 20-40% battery PER HOUR of use on the phone at 25% screen brightness playing a card game online (no wifi, just on HSPA+). This is on a BRAND NEW flash of KH2 (GB 2.3.4).
The top half of the phone gets really hot and battery drains like crazy. ceasing data use cools it down and reverts to normal battery use.
Which one do you guys prefer
I unplugged my phone 5 minutes ago its already on 97%, any suggestions

Neither, bit tend to interfere with advanced configs and from my experience power users tend to advoid them. However, juice defender seems to be the lesser of the two evils. Personally I undervolt and underclock and get far better results
If you don't want to get into kernel changes (undervolting/underclocking), give JD a try. I've been using it for months and found, at least for me, a significant battery power savings using it. Spend the extra couple of bucks and get the JD Ultimate key.. it unlocks a bunch of features. With the same type of use I noticed about a 6 hr gain/day (was getting ~ 14hrs on a charge.. now anywhere from 20-24 hrs). There are many setting combinations, so you'll have to experiment what works best for you. I have it set to turn off the data connection when I'm on WiFi... and when my screen is off, have it set to turn off all radios (and while screen is off, you can set it to ping certain apps like gmail, facebook, etc just for a minute, then turn back off. It automatically will turn data on when you leave your Wifi area. You can also train it to turn on/off certain radios depending on your travels, time of day, use of certain apps, when battery gets to certain levels, etc. It has some cool widgets which show which radios are on/off and can be quickly toggled as well. Anyway, it takes a while to figure out what works best for your situation, but it is very flexible and has tons of features.
Contradictory to what I've been reading online about battery saving apps; I had GREAT results with easy battery saver. I know the app looks cheesy and the fact that i never heard about it before downloading from market.
Due to poor network signal at work, id barely have any charge left on my phone once i get out of work (8 hrs). this kind of apps really help.
JD seems to cause more conflicts/problems that it helped me, even if i turn off untested/expirmental. JD looks more sophisticated/advanced, it didn't work well with me.
The features which mainly effects battery life imo are:
1)Traffic scheduler
2)connectivty killer when screen is off.
These are must features for me, to get whatsapp msgs and email sync. and it seems that easy batter defender scheduler is more robust.
I usually choose to allow sync every 15 min with 30 sec window and connectivity killer to around 20kb/30s. I had bad results when letting the app manage my wifi connectivity based on location (remember wifi networks), better turn it off.
Other settings, screen timeout/brightness/UC/UV/cpu cores/deep_sleep/kernel/modem, must be explored to get max battery life.
Remember these apps will not help very much, if you are using your phone(i.e. screen is on). they work best when phone screen is turned off.
I'm currently using Battery XL from market to test it out.
Another app worth looking at is Green Power. It also can shut off data and turn it on in intervals for emails, IMs, etc.
They both are good options. I have used Juice Defender for several months and it is very good. I have installed Easy Battery Saver last week and it is also good. I only did the change from one app to another for trying

Also in case any one is wondering, i did play games and videos on it for hours at 100% brightness one day to try to get the overheat warning to come up but never did, i guess thats only a problem with the korean models.

Battery gets better without knock on. I also carry my phone in the carpenter pocket of my pants and turn it on a lot with knock on. You realize even if you dont turn it on though every time you make enough contact to consist of a touch you rev up the cpu? So you can well imagine if you carry your phone screen facing leg for protection that you are chewing through battery pretty good. To each his own.

At 3 days, my G3 wasn't getting exceptional battery life. But now that I've had it for a week and a half, the battery life is insane. It's been getting better every day.
I don't have anything disabled and I am completely stock.
EDIT: I did disable all bloat possible though, same as you.
Do you have to be rooted in order to use greenify? I can't root this phone due to work.

Yes. You must root and install the xposed framework to use Greenify.
There might be similar programs out there that don't require root, but I bet they don't work very well. Having administrator privileges would pretty much be a requirement to assure the app could kill off any processes or apps that it needed to. Without root, the app probably will not be very successful in closing things out.
my battery life has been getting better. Yesterdays was at 2 1/2 on screen time after 13 1/2 hours off the charger and had like 58% of battery left. Im just rooted and removed carrierIQ. If It stays like this or gets a little better i'll be happy considering its a stock ROM and stock Kernel obviously... so if we can get to a point where custom roms and kernels are possible this will be fantastic!
Lte for over 4 to to hours and WiFi the rest of the time. 30 min call, lots of YouTube,spotify,all apps syncing, Facebook,lots of Google + and lots of browser time. Rooted debloated. I'm happy with results better then my nexus 5 with a custom kernel
