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

There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...
10 minutes of on-line gaming (storm8 games) = 10% drain
WiFi off, gps off, mobile data on, screen brightness on auto, stock rom

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.
Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks
From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.
So I've been having some weird battery drain the past couple of weeks. I have been trying to watch it and try to find the source of it but cannot seem to nail it down. I dont get that spectacular of battery life overall. First off, I am running zeus v6 with kl2 modem and nothing else done and no overclocking. Battery drain seems high overall, but above 50% battery its not too bad, however once it gets below about 50% battery the drain noticeably increases. Today for example, I unplugged my phone at about 8am, light usage pretty much all day, at 4 or 430pm it was about 50%, I get out of class at 7pm and the battery is down to 20%. Only thing I noticed was that I turned wifi on and left it on but it was connected to a network the whole time so its not like it was searching for a network. I had only about an hour of screen time, maybe a bit more. Its like this every day no matter what I do. I rarely get over 12hrs of battery life. I even got a new oem battery 3 or 4 weeks ago to see if that help but it hasnt much. I'm starting to wonder if it might be related to my phone that I just dont get as good of battery life? Not sure what to think, Im going to try flashing another GB rom in the next couple of days to see if that changes anything. I will post some screenshots of my battery life later tonight for you guys to look at. Let me know if there is anything else you want to know. Anyone else experiencing weird drain like this?

I had tried the two most recent versions of Zeus, and had unbelievably high battery drain. No WiFi or GPS use at all. If I was actively using the phone, my battery power would drop at roughly 1% every minute or two. And that's with screen brightness turned all the way down. Even with the screen off, it was pretty bad. I'd lose something like 7% an hour, with the phone sitting unused. I had basically the same results with Saurom. I pretty much just chalked it up to something within the ROMs themselves. I get great battery life with stock GB, CM7.2, and Paranoid Android JB.
I was reading that thread you posted qkster and it didn't really seem to be having the same issues as were in that thread. It's more just like no matter what I do the battery drains normally above 50% but below that it drains way faster even with less usage and not doing anything different.

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.

I have never had a battery be this good. Rooted with Greenify. Running Skyfall.
Kinda ridiculous. 16 hours and 60% full over here on just regular power save mode....SkyFall also
Yeah this phone gets way better battery life than my s4 did with same size battery. Love it. Does greenify really work that well? I have never used it as I have great battery life without it.

Lots of reviewers are talking about how the M8's battery lasted longer than the S5 too. Samsung needs to stop slacking on the software and give us a lightweight touchwiz. I absolutely love Sense 6 and I'm usually an AOSP guy. I'll probably try out GPE Roms once they're stable but honestly the new sense is everything I want out of android software. Minimal, clean, customizable, smooth and fast.

did you guys flash sky fall with twrp or cwm? been looking to flash it
CWM. Always been wary of TWRP. Not sure why.

Twrp here. I've always been wary of cwm. Lol. No joke. And yes, the battery on this is ridiculous! I used the ONE MAX today to do a test. And we all know, it Has a bigger battery, 3300 mh. The M8 beat the MAX. Did the exact same things throughout the day, and no lie, the M8 won the test.

Don't get me wrong, I'm getting great battery life as well (though coming from a VZW GNex, anything would be an improvement). However...posting screenshots of how long your device has been off the charger with no other information (screen on time, app battery use) doesn't tell us anything.
Hell, I could leave my phone at home on wifi with the screen off and not touch it for the next 3 days, take a screenshot of any remaining battery life, and post it being like "OMG I got 3 days of battery life, this is amazing!" And it would be just about as informative and truthful as your screenshots (not including yours Evocm7, obviously).
sorry im kind of a noob i am aware of greenify i have used it but whats skyfall? I tried searching but nothing is coming up but james bond.
EDIT: Sorry havent looked at roms yet im just rooted atm

I hear what you're saying. Personally, I'm not trying to participate in any scientific study on the matter. All I know, and all I care, is that I've had the phone off charge for 29 hours now... using it the way I normally use it during an average day ( pretty light)... and I'm still at 40% battery.
Coming from a malfunctioning POS Droid Charge this phone is a godsend. I used to have to carry an extra battery just to get through an 8 hour shift at work starting on a full charge.

lol I came from a GNex, so we're probably in the same boat. Even on wifi with extremely minimal use (10-15m screen time all day, which with how slow and laggy it was I didn't really care)), I would be down into the 60%'s by bedtime. If I went to the gym with full battery, after listening to Pandora while doing weights, and watching Netflix during cardio, it would be into 20-30% by the time I left, total of maybe 1 1/2 - 2 hours.
I flashed Skyfall the other day after charging my phone to full, and by the time I was done flashing, re-installing everything from TiBu, updating a few out-of date apps, and setting everything up, it was down to maybe 95%. And that was with the screen on for probably 20 minutes straight.

I think taking into consideration the snapdragon 801 chip how it saves battery, sense 6 being light weight, if one needs to you have the choices of battery save mode and if that's not enough extreme battery save mode! This phone came built up from the floor up. Now if we just had the 1.56 software version with all the above included stock and operating correctly, I'm sure we would see even more battery savings!
Im looking for good app for monitoring battery use. Is betterbatterystats the de facto standard?

There are very few "de facto standards" for anything in the Android ecosystem...which is why we like it. I use a combination of GSAM Battery Monitor with the root companion, and Wakelock Detector.
Dont get me wrong, I get decent battery life, but nothing like you guys. For those of you with amazing OST are you guys using Google Now? I just installed wake lock detector to see what is causing my batt to drain more than others.
