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.

did you guys do a full battery break in? I charged my phone to 100% drained it till it died charged it to 100% again with the power off then drained till it died again... I have great battery life.

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

A simple question. Does using the flash on my nexus phone as a flashlight damage the led? I read on some forum that one should not keep the light on for more than 15 minutes as this might damage it. Is this true?
Thank you.

No. Its just a bright led just like any flash light. It probably uses a lot less battery than the screen and will not be damaged when on for long.

Used LED as stroboscope (think 100ish bpm) for 2h after a car accident. It is still functioning today. However I do know of ppl who killed their LED within 30mins of using faster blinking flashlight.
My first Post, new sns owner since 3 days ago!
HiPower led's like those used in flash tend to get very hot if used continusly.
And since i dont imagine it having some sort of cooling, the led's itself can get damaged, or even the solder will melt and flow out of the connections.
I think the flash led system was only designed for some hundred miliseconds use.
Like overclocking you can only push it so far before damage, and it tolerances vary from unit to unit.
btw, what flashlite app do you recommend?

Turning it on and off constantly could simply reduce the life of the led light so that makes sense. But as far as having it on for long periods of time I think would just drain battery.

The Led itself actually no. But you may damage the drive circuit if is not designed to work at that frequency.
I have designed systems that work 24/7 at about 100hz and they've been working for years!

Tiny Flashlight + LED.... been using it for over 2 years now
First thing I want to say is that I didn't create this app.
But for everyone who finds the bLED idea kind of handy: NoLED does it too, but in another way.
Here the link to the thread:
http://forum.xda-developers.com/showthread.php?t=730692
I confirm that this application works very well on the GALAXY NOTE.
Thank you to the developer.
BubbleBuzz is better
Thanks. NoLed is an amazing app

Screen based "LED notification" are not that healthy even with the SAMOLED, the screen is still lit and voltage is going through the screen and not only that but you also degrade both green and red OLEDs as they stay on even when a black picture is displayed as backed up by this post:
http://forum.xda-developers.com/showpost.php?p=21560940&postcount=103
But if you dont care of any of those then its pretty ok to use at the expense of battery life.
An amazing app indeed. If only it didnt eat my battery. Since removing it I went from 1 day to 2 days on a batterycharge.
Not giving noled all the credit tho, also switched to LA4 a few days ago.
Nice application works very well on the NOTE.
I am a Noled user for 2 Years now, Its the best! ű
I tried iLED and it munched the battery in hours.
After installing Better Battery Stats and researching wakelocks, I understood that screen based LED notification apps will cause the phone to constantly remain in a state that drains the battery, not just the LED draining it.
I believe bLED operates differently and so doesn't drain the battery as much.
madmack said:
You see the major problem with NoLED is in the Android framework. a) Android doesn't allow the CPU to deep-sleep if the screen is on regardless of its content. b) The black pixels are actually switched on. Even though I believe that our screen is capable of switching partial pixels on, the Android API simply doesn't give access to this feature.

Yeah, not only that, but NoLED wasn't working very well for me anyway. It kept coming on even when the screen wasn't sleeping (e.g. over running satnav...).
I am hoping that somebody will eventually add support for BLN to the kernel! I've seen BLN on Nexus S and it looks ideal.
I know I've asked this Q before but can't find the answer and its driving me mad. Google searches turn up the obvious "go into settings>applications>development >screen will never sleep while charging" - The problem is my screen DOES sleep while charging. I had it working for a while but have recently returned to bone stock through a fxz and the screen will NOT stay on while plugged into any type of charge ie; wall wort, computer, car charger etc. Its really a nuisance because I like to have the screen on while driving for easy access to my music widget. Any ideas?

Stupid question, perhaps, but do you have your screen timeout set to anything other than "never"?

Yes I do. Is that the only way "stay awake" is supposed to work? Seems a bit redundant. I know for whatever reason the phone was behaving differently before I wiped it. I've always set it for a 2 minute time out but if it was plugged in it would stay awake.

Not sure, I always set to "never" timeout because I like the option to put the phone to sleep via power button and at my discretion... still won't stay awake with the timeout settings while charging?
I wiped car dock data, rebooted several times, tried plugging in then ticking off the box, unplugging the ticking off the box... no screen time out, etc. Its not working like it should. I know I had this problem months ago and can't remember what remedied it. Lots of ROMs and tweaks in-between then and now. But bone stock it never worked out of the box if I remember and its not working now that I'm back to stock. Weird. I'm thinking of giving "better battery stats" app a try. This has to have something to do with wakelocks. Any other ideas?

Try Better Battery Stats (I've used that app) or try Watchdog Task Manager to check for wake locks.
[Light bulb goes ON over head] Here's an idea. Maybe there is no official "display" stays on while charging. Maybe the developer setting is to keep the screen/CPU running even with the display off. I've done as you do and set the "display" to never time out. Also I've ticked the box to have the "screen" stay on while charging. It might be my imagination but the display appears to jump to life when turning it on via the power button now while on the charger. There is no delay whatsoever. Does that make sense? Either way, I'm gonna run it like this for a while and test that idea. I usually use the power button to turn off the display anyway instead of letting it time out. I just always liked that auto-off in case i forget to turn it off before pocketing it. Thoughts?

Let me experiment on my phone and see if I see the same things you are. I'll let you know what I find out...
The ONLY way to do what you want is to either do as you did and do a "never" time out, or to go to:
Settings --> Application settings --> Development, then check the Stay awake option.
YOU MUST BE PLUGGED INTO A CHARGER FOR THE ABOVE SETTING TO WORK!!!
I will be 100% honest here, and that I have the HD dock sitting on my desk and when I connect it to the charger on the doc, it NEVER turns the screen off, and I do not have the Stay awake checked in the development menu. I also have my timeout set to 1 min.
Then theres that whole "in pocket detection" thing going on lol. I finally have that working with the current settings. Woohoo! So that means no worry that the display stays on if I somehow forget to use the power button to switch it off. I'm just fine tuning all the features of stock GB and now along comes ICS. Ha-ha.

Achieving perfect powder management always seems a bit elusive for me be it mobile devices, laptops or even some desktops. Then, just when I have it fixed some newly installed app will come along and knock it all off its precarious axis. Here's hoping ICS has better management.

I get 48 hours on a charge with HEAVY use, and tethering since I am at client sites alot, and that means usually no internet for me, unless I wifi tether.
I can go 36 hours and be at 25%, and at 44 hours I am at about 10%. I charge my phone every night if I can, but when I cant, I can squeeze 46-50 hours out, with out changing a thing. I don't play games, nor do I allow adds, have all adds blocked on my phone with a hack to the /etc/hosts file. The ads block is in most of the custom roms in the dev section too.
I am bone stock with root right now, while I work on a few things, so that might change things a little.
right now I am at 18 hours and 40 min. on battery and I am at 85%

Yes automatic brightness, 1 min. screen timeout, my battery is in performance mode.
I am also not overclocked. I have ALL of e-mail checks, and calendar syncs always on and they check about every 5 min, even when on 3g/4g.
Now I will say that if you are in an area that switched between 3g and 4g a lot, that will KILL you battery fast. There is a customer that I go to often and when I am at their building my phone switches between 3g and 4g when I move from office to office, and go to the restroom, and my battery barely lasts all day.

same if you are somewhere with a poor wifi signal that keeps witching on and off
Here in the Florida Boonies we go from 4G to Edge and back over and over again all day...but still, I use my phone moderately heavily, am overclocked to 1200, with everything syncing over whatever data is available and with wifi turned on all day, and I usually only go down around 40% over an 8-9 hour period. Compared to my last phone (Samsung Focus, which had decent battery life elsewhere) that's amazing. I literally had to plug that one in at my desk to make it to lunch down here.
As a matter of fact, while I've been typing this message, I've gone from 4G to Edge, and now it's back on 4G. Crazy system down here.
I've mentioned before that I run a hotel...well the other day, we had an AT&T engineer check in, and I asked her about it. She pulled out her Blackberry and said "I have 5 bars. Get a Blackberry." She wasn't thrilled when I told her that my backup is a Bold 9700, and I have the same problems on it. She said she'd look into it, though, so maybe there's hope.
Seeing how this thread has kinda evolved into a battery/connection topic; do you guys enable background data? I do and I get about 10-12 hours of hard use. I'm listening to music, on these boards, browsing the web, making a few calls, texting etc.
Sent from my MB865 using Tapatalk 2
Oh yeah. I literally live where I work, so I have all of my data turned on...I'm never far from a charger. Like I said, I get through the entire day without charging. I call, text, and email constantly. I use it as a music player in my office. It takes voice memos. I take pictures constantly. I'm always reading boards or books in my downtime, etc. Pretty much everything I used to lug a laptop for, I use my phone for now.
I need a tablet. Waiting to hear about the specs for the Asus tablet that's rumored to be one of the upcoming Nexus devices, or their MeMo, assuming that they're different devices at all.
I reported this to moto a long time ago the select is not doing anything when you check the box.
I fixed mine by installing power widget and doing the toggle to stay awake with it then uninstalling it.
Worked like a champ
This is a little bit of a boast, I guess you could say... but also educational in a way.
This is my most recent battery life. I found that when I posted my screenshots, people think they are faked in some way. (Posted it here and other GS3 forums) They are not. I am using the stock battery my phone came with. NOT an extended battery. And you can see from the battery graph that the phone was not charged. I guess this is to show that you can use your phone heavily, and still get amazing battery life.
I am using the stock jellybean leak. Not rooted or unlocked.
This is everything I have done to get good battery life.
-I turned the LED touch lights off (I don't like them, they're so bright)
-I have all vibrations off. My phone does not ever vibrate.
-I have power save on.
-I have S-Voice "wake command" off.
-I have motion control disabled.
-I am almost always on wifi (work & home)
-When I am on wifi, I turn mobile data off.
-When I am going to bed, I put my phone in airplane mode.
-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-I have my sync OFF. I check my email manually.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.
-Always have a dark background, if possible.
Thats everything. Mind you, I didn't make or receive any phone calls on this cycle. But I did use my phone, as you can see I didn't just let it sit around. Device idle was like 3%?
Anyone else a "hypermiler" like me? I don't get this much screen time every time, it ranges from 5-7. I've gotten more than this and I've gotten less.
Hope this can help even if it's only a little.

-Clearing the ram too much actually drains the battery more because certain apps will have to auto start again every time you clear memory
-Keeping it at around 0-30% all the time should save you more.(I can still see my screen during the day at 30%)
-That doesn't do anything.

-Are there no A/C outlets in your bedroom?
-What the previous guy said, this is a stupid thing to do. Java was designed around efficient use of resources, and restarting running apps (which would happen, unless you have them removed entirely) would use more processing power than you had saved by not having the tasks running in the first place.
-Using Auto is causing the system to periodically poll the light sensor, draining more battery than used otherwise.
-This is how you kill Li-Ion batteries (one way, at least). The whole spiel about discharging fully, THEN charging fully or the battery will have some sort of "memory" of capacity less than actual capacity is how Ni-Cad rechargables work, not Li-Ions. Li-Ion batteries are the opposite. For superior life, keep them topped up as much as possible. FYI
I hope THIS helped, more than a little.
There are plenty of outlets in my room. Lol I just don't need to use them that often as you can see also I hate getting calls and messages in the middle of the night but I use my phone as an alarm sometimes so airplane mode just seems convenient.
This is just what I do. I mean, some of the things I do may not help at all. But this is what I do with Android phones and I've always gotten really good battery life. I've always, always gone down to 1% then charged up to 100% and I've never had a battery go bad on me. Then again I only ever keep a phone for 1 year. I do know that these batteries don't have the memory problem, I just can't bring myself to not fully discharge or charge. I have mild OCD, for real. Little things like that brother me
I'll play with backlighting to see what that does for me.
I've gotta be doing something right. Idk about the task manager, I've just always liked not having programs running if I don't need them to be. I know they arent "running" but it just gives me peace of mind, I guess.
Thanks for the recommendations I will try them.

You getting really good battery life =/= you getting the best battery life possible.
I have pushed ~2 days of battery life without charging many times on my GS3 (with all the bells and whistles running, just mobile data turned off when i'm not commuting), i just don't have a reliable measurement because:
1. I'm flashing mods/roms/kernels/whatever multiple times per week, and
2. I usually charge my phone when it's convenient, which is fairly often.

I stopped flashing because of my OCD. I mean, I'm not crazy but it causes perfection issues and all the ROMs I was flashing had glitches here and there and Idk if you've known anyone with OCD but with the perfection issue, those glitches were all I could think about. So there went flashing. Lol.
Also comes into play with the charging thing. You seem knowledgeable in what you said but even though you said keeping it topped up is best, in my mind, that's destroying my battery. Lol. I really do appreciate your info though.

I'm glad you said it, so that I didn't have to. :silly:
I read your post and the first thing that came to mind was, "there is medication for that, you know.":laugh:
Here's my .02. My battery never lasts that long. Not even close. I'd feel disappointed if it did. I bought my gsiii with the intent of gobbling up unlimited data and using the oc'd processor to run apps till the phone is so hot I have to set it down. I've burned up almost 6gigs of data since the 7th. I get around 4 hours of screen on time most generally. I also throw it on a charger whenever I have the chance. My battery rarely dips below 50%. Like others have said, full discharge cycles are for ni-cad batteries. Li-ion doesn't benefit. Good battery life for me is the lg flip phone we have on a diff line that lasts a couple weeks.

Okay, okay, as long as you admit it... I'll stop being a snarky jerk. I'm totally the same way though. Perfectionist to the core.
It's a very bad idea to let the battery go down to 1% regularly, lithium batteries should be charged more often for better life and more cycles
Sorry but I still just don't believe 7 hours of screen on time. 4 is above average even amazing screen on time for this phone and stock battery. I suppose there is the possibility of using 0 percent brightness, or even lux brightness or something similar to get the brightness even lower.
You said you use auto brightness, I'm sorry I just don't buy it.
People with the extended batteries are getting 7 hours of screen on time not stock batteries.
7 hours of screen on time is literally double almost every other phone on the market with stock batteries. I really fail to see how having minimum usage and a high performing rom will get you double screen on time.
Edit: with that said, in my current situation I will never have wifi access plus I tether a lot so I really have yet to personally see screen on time since I rooted. Before root and stock I got about 3.5 of screen on time.
Not trying to be a douche or anything just very curious about how 7 hours comes about.

you dont get 7 hours because you are not doing what op did for perfection, and you just like other "4 hour" guys in this thread. I can confirm 7 hours usage is totally possible and what left can support one day idle time when you turn off data etc. Iusually dont do that because I like my phone work at full functionality, but I also like tinkering around to keep maximum use of juice, by eliminating wake locks and autostart.
killing background helps sometimes because some stupid apps keeping using cpu after backgrounded. op go and get a iphone, its perfect for OCD since it can get zero unwanted background activity, amazing idle time and stable usage with relatively easier configuration and tweaking.
1% is NO. 1 battery killer, heat is NO. 2, top up at 100% is NO. 3. Li based battery is at best 40%. but plaese its just a phone, charge and use anytime you want. phone outdated way earlier than battery.

While I understand what you're saying I think you misread my post. I was strickly referring to the screen on time which 7 hours of screen on time with stock battery is inconceivable. 4 is about the most you would normally see.
7 hours of USAGE is common.

Well I mean. You don't have to believe me. I mean I have nothing to offer but my word. I do use auto brightness. But because of the suggestion I'll probably set it to manual and see what that does.
I got 7 hours screen on time with the stock battery. The battery says "3.8 v li-ion battery"
I've gotten more than this is the past but I've also gotten less.
Like I said you don't have to believe me but... I'm using the stock battery.
And to the poster who mentioned to get an iPhone - I have one for my business line

battery statistics are poor statistics in general. there are too many variables. luckily we have removeable batteries if we need mroe juice.
heres some postings to add to the mix
put my phone through the paces with fantasy football.
held up pretty well. stock battery mind you. on pace for nearly 8 hrs of on screen time. This isnt with typical use though... With typical use I can get 20hrs and 5-6 hrs of screen time. I thought anywhere from 4-6 hours of on screen time was what people were suppposed to be getting.
Yeah we all use our phone differently. I rarely actually talk on the phone with my GS3 because I use my iPhone for that. But everything else I do on my GS3, reading news, some browsing, xda.
I just thought I'd share what I do for people that may want to get better battery life.

Then I shouldn't use the word "usage". I meant 7 hours screen on time. Sometimes I got 8 or more, but only use it continuously after charging, no idle time.

Yet that involves turning off data. IMO the smartphone should always stay online. In my experience, iPhone can get constant -4 ~ -5ma juice flow during idle even with data (2G) and all the push notifications on, which are the only things I want for stay online. I feel its hard to get similar result on my GS3 though.

I'm always online, whether it's wi-fi or 4G. Luckily I have wi-fi at home and at work.
Like, literally as I'm walking out the door of my house, I turn on my mobile data, and when I get to work I turn it off. When I'm leaving work I turn mobile data back on and when I get home I turn it off.

what you did is pointless. If you leave data on, data is not connected when wifi is connected, and it will connect automatically when no wifi connection.

It's not pointless to me. As I said a few posts before... I have OCD, obsessive compulsive disorder. Things like this affect me. I know that being connected to Wi-Fi that data is not connected, but in my brain, it's as if something is telling me that because my data toggle is on, it's running.
I really can't help it.
