[Q] My Stand-By time is about 10 Hours

If I were to leave my phone on without using it, it would die in about 10 hours. Is this normal? It's been like this since stock. I don't think this is normal since my G2 had way better stand-by time.
Please, don't say it has something to do with your settings and stuff, because I had the same things turned on with the same apps on my G2 with way better Stand-by time. GPS and Auto-backup.

Im running bone stock. I recharged after 38 hrs. And still had a 30% chg left
These were 14 hrs after complete chg.

See? This is what I'm not getting. Even since stock my Standby time was horrible. So I rooted to get better battery life. Nothing is changing. I even did a battery calibration to see if the phone was just reading the battery wrong.
I have another question. After the phone is finished charging at 100%, as soon as I take it off the charger, it goes down to 99%. Is that normal? I thought the phone was supposed to stay charged at 100% for a little while.

I just unplugged mine from complete charge and as soon as I unplugged it went to 99. So, yes????

That is normal to drop to 99% immediately. I always charge to full before I go to sleep at night and for some reason if I leave wifi on, the drain is really low when not in use...

Ok. I have no idea what is going on, but my phone just randomly rebooted, froze and then reset my home screen replacement launcher (as if I hit set to default), and now when I went to check on the battery usage and this is what I get:
Android OS is now at about 2% along with other things.
Display is at about 50%.
This is new. Android OS used to ALWAYS be higher then display. That didn't make since.
Now things are different. It seems the display is using the most energy. That is normal. I expect that.
I don't know, but it seems that everything is back to normal. I am using the phone, so I'm expecting this battery drain, but I'll check to see how much battery is drained on stand-by when I go to work later on today.

Let us know how it works out for you. Display should definitely be at the top if you are actually using the phone. At least it always is for me

If you want your phone to last you throughout the day, make sure that "Use Wireless Networks" in Settings -> Location is unchecked. That is the biggest battery guzzler this phone has next to 4G and Brightness. My battery loses 2% all night til I wake up (Thats 8 Hours!!)

I figured it was a Samsung thing. I leave GPS off if that's what you mean, but location services stay on. That's just a me thing.
///////////////////////////
Today after work, I lost 30% energy on standby. That's alright with me. It was about 6 hours of straight standby time. It seems to have gotten better. At times I'd lose at least half of my battery after at least 5 hours.
I don't know how the phone seemed to fix itself, but doing things doesn't just DRAIN the battery anymore. I was playing on the phone fixing my home screen launcher and my battery wasn't dying right in my face. I lost like 2% after having the screen on for about 20 minutes fixing up my settings compared to seeing 5+% in like 10 minutes.
I am satisfied.

Lol, your battery didn't fix itself, that sounds like somethings wrong with the battery cycle. Maybe you need to recalibrate it.
You see, sometimes if you overcharge a phone, especially when using a charger that isn't made for that specific phone (usually a charger thats too strong) it can throw of the charge cycle. Thus, it can take like 30 minutes to drop 50% and then another 3hrs for the other 50% (this is just an example). If you're rooted, I highly recommend doing a full battery calibration.
Secondly, the Use Wireless Networks thing in the location isn't really a samsung thing, i think of it more as a google thing. I noticed that when its on, Google is always sending information back to itself, thus keeping the phone awake longer. Thats why if you go to your graph, it show that your phone is awake more often then it should be. I personally uncheck it, because if i ever need it, I just quickly switch on the gps. Then turn it off when im done.Thats my recommendation to you. Yesterday, I personally got a full 24hr usage out of my battery, and it wasn't even all that light. I texted most of the day, made a few calls, browsed the web, and listened to music for a few hours on the subway. Pretty moderate usage.

See, I'm not exactly unhappy with my battery life... but seeing what other folks around here are getting MAKES me a little unhappy.
I mean, I went to bed at... I'll say around two AM last night at 90% battery. My audio book player ran for thirty minutes after that; woke up at about eleven AM, 53%. NOTHING CLOSE to what you folks are getting. All of the big culprits I've heard mentioned have been checked out, and I just calibrated, so I dunno where else to go with this.

Does anybody see anything unusual about my battery life?
My screen has basically been off, yet I'm still losing weird amounts of battery. Based on the hours, I took my phone off the charger at 4pm Dec. 04 (16:00) and it died at 6am (06:00) Dec. 05. That gap in WiFi was my time at work.
Those bars you see in display right before WiFi get's turned on is me texting and Facebooking. Apparently I wasn't using Facebook enough for it to actually get a place in my battery usage.
And of course those two little bars in the red was my phone telling me that it's dying. Too bad I was sleep.
Ignore the rise after the fall. That's it charging of course.
Also, if you notice, my WiFi apparently wasn't using anything to get a place as well. Those are all the apps that were listed. Why isn't WiFi there?
I calibrated my battery twice already. I can calibrated it again since it fully died. Let me make sure I understand how to calibrate it.
ROM: ACS Syndicated Ice
Kernel: LoS Kernel
1) Phone charged to 100%
2) Phone dies
3) Charge phone to 100%
4) CWM and wipe battery stats
That's what I do to calibrate it.

Add a 5th step which is using the battery calibration app from the market. Also, uncheck wireless networks from location settings (huge battery hog). I assume that's probably your biggest problem. Then, if you are rooted, do what I did, which is get a root explorer and go into system>apps, and move the social hub.apk and media hub.apk to a folder on your SD. It will essentially uninstall it. Those 2 apps are battery hogs as well even if you have never used them. They will always run in the background. Try those and lemme know if it helped.

Wireless network location settings is also mainly used by Google to send them data about your usage. I noticed a significant decrease in battery life whenever this is checked. I would rather just turn on my GPS whenever I need it than keep this function on at all times. Its just not worth it in my book.

Horrible battery life while just being idle?!!?

I've had this phone for about a month. Started off on stock, and rooted it and flashed different ROMs and kernels. I never really got good battery life with any ROM. Typically I would get around 7 to 10 hours of moderate usage.
I fully went back to stock firmware and kernel using ODIN, to flash 2.3.6. I rooted it and removed some bloatware apps. BUT, the battery life seems so bad.. it's been 2 days, I've done calibration 2 or 3 times.
Leaving my phone idle, in one spot, I lose about 4-5% an hour. 4G Data on, wifi off, 2/4 bars of signal, sync on (only gmail, google docs, contacts, calendar).
But today, I think it got worse, as shown here: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230121.png
Graph: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230126.png
Note: the data icon on top shows that it's on 3G, because I moved out of good signal area when I took the screenshots. The phone was idle in a spot with 4G getting 3-5mbps.
What's wrong with this? The phone is a month old, so I don't think it's a battery problem. I've calibrated 2-3 times since I went back to stock.
Also, don't recommend me to use Juice Defender. I use Google Voice to call and text, so I need data on all the time. And I know this phone can last over a day with data on (my friend has the same phone and it has lasted 2 days on one charge, completely stock firmware).
ALSO, when I press "Android System" on the battery history, here's a list of what it shows:

Actually that would be more of light/medium. Checking facebook every 30mins, a few texts now and then, playing a game for 30 minutes, listening to music for an hour, a call or two about 2mins each, a few instant messages on facebook, GPS use for 5 minutes, and idle for about 5 hours. Brightness at 50% or below. All on data connection, no wifi.

I see easily over 12 hours on a charge with my phone, and i use it heavily... 2 to 3 hours of phone time (at the least) wifi tether here and then, a lot of facebook iming and checking. Reading....
Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

Your battery looks fine. Playing games rapes the battery. Also 4g rapes the battery.
There are ways to improve the battery but like you said... You need to use all of these features.
Go get a spare oem battery or a reputable extended battery.

Im at 52% right now, 34% display, time on 3 hours 14 minutes, and sitting at 1d 1h 39m on battery. Light usage.

Something is definitely draining your battery. As you can see your phone is awake when the screen isn't even on. It's just likely an app you downloaded or something in the background. good luck narrowing it down

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?
Run some actual tests to clarify the issue first..
There. I said my peace

If you tried everything else try recalibrating the battery.
I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.
To Recalibrate Battery (must have custom recovery like cwm):
Charge phone to FULL
(I highly recommend AC charger for this)
Reboot into recovery
Look for wipe battery stats (should be I'm advanced if not main menu)
Unplug phone and restart it
Now FULLY KILL THE BATTERY
(for faster results set mp3 or video on repeat and let her rip)
Fully charge one more time and done
(again I highly suggest AC adaptor)
Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.
Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.
So your post is useless and rather a waste of everyones time even reading. So thanks.
@above
Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.
@OP
As suggested above use cpuspy to check on the cpu when idle,
Sleep mode should kick in within 30sec to a minute.
Also chek my reply a few posts up and follow steps there..
Ignore Realn00b's post
Again:
@Realn00b
Please take the time to read up on batterystats.bin and find out what its for,
You don't need cwm to delete, just root explorer.. its in:
Data/system/batterystats.bin
Also, the entire basis of this is stupidity and was takin way out of context.
Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)
And should only be deleted under very very rare occasions (effecting above)
Your battery percent, is actually the mAh
Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.
The device then calculates from these the value we know as the percent.
Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.
Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks

I originally purchased it for two reasons:
1. For long trips or for when I'll be gaming a lot
2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.
Also, I'm on stock kernel. Everything stock + rooted.
I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).
Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).
It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.

Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend
Deleting unndeeded applications and even replace stock with third party where applicable.

Battery draining way to fast

I let my phone completely die last night because I wanted to get a full charge on this thing. I wake up this morning, and after 4 minutes, it had gone down 4%. It has now been 7, and it's down 7%. Anything I can do?
PS, it is now down to 90%.
Running Calk's rooted FC15 with ics4ics theme and the lockscreen mod.
88% now.

Been on it since Sunday. Location services are not enabled. Yesterday I noticed it had gone down faster than before, battery only lasted just over 8 hours with minimal use, but the wifi kept disconnecting, as did the 3g when wifi was off (this didn't happen in gingerbread).
I wonder if I don't need a new battery. I have noticed battery performance getting worse and worse over the past couple weeks.

I wonder if I don't need a new battery. I have noticed battery performance getting worse and worse over the past couple weeks.

I would take your battery and have it checked at Sprint. They will replace it for free if it's bad. My battery gets better after a day or two. I lose 2-3% while asleep on wifi and regularly get 4-6 hours of screen on time depending on how I use my phone. Did you check your wifi sleep policy?

Check what accounts you have setup, and if anything is syncing.
Goggle+, dropbox, and other applications have auto picture sync options which will KILL your battery.
Also location services in google or westher applications, and as always poor signal or no signal.

Yeah, I forgot to mention the sync options. That taxes the battery big time
Sent from my Nexus S 4G using xda premium

Sync is always turned off.
Well, I tried something: pulling the battery for a minute, then when back in, plugging it into the charger. I would give me a false full battery light, because when I unplugged, it showed 90%, and it kept doing this every percentage point, so I kept unplugging and plugging until it showed 100%. Well, 10 minutes have past, and it hasn't budged. So I'm chalking this up to false battery stats.
Thanks for your suggestions!

Yeah, I was going to mention wiping the battery stats but I figured someone would say that does nothing. I always do it when I set up a new ROM even though some do it on install

How many apps do you have installed? Could be a rogue app in backround eating your battery up.
Also with wifi/3g constantly disconnecting also taxes that battery juice faster then a constant steady signal.

FYI, I am having this same problem on the same ROM for the last couple days. I thought I had isolated it to a problem with having USB debugging running when charging from the computer but that's not it either. Last couple days battery is draining so fast that I lose charge while plugged in! Have to charge from wall plug to get an increase in battery. I am having Android OS AND Android System at the top of my battery stats eating 35% and 34% respectively. Clealry not due to syncing or email checks or anything similar as this is the exact same setup I have been running for months (other than the upgrade to Calk's ICS ROM). I'm baffled....

Install these 3 apps:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
This app will tell you what is holding wake locks on your device. Anything over 30 minutes over the course of a day would be problematic imo. But it depends on what you have installed.
https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy
This will tell you how much time your processor spends at each clock speed. Deep Sleep should be close to 80% with moderate use.
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
This will show you your percent per hour usage of battery. It's optional, but it helps me debug battery use. Typically I run 3-6% per hour with moderate usage.

So it figures, downloaded those apps, rebooted the phone and now its not happening anymore. This has been the problem the last couple days, its intermittent so I keep thinking I've figured out what's wrong and then it happens again. I'm thinking about going back to Gingerbread or trying one of the AOSP roms to see if the problem persists...

I noticed FC15 has the worst battery of all the leaks so far. It a joke shouldn't have even been sent to sprint for testing.

Gonna have to disagree with you there, maybe you have a bad flash. I'm getting an average of 16 hours with fairly heavy usage. FC15 has been fantastic, no issues whatsoever.

Im having kinda the same problem. I just had to get my rooted phone replaced yesterday not that it matters it was rooted I had no roms or nothing on it just rooted at the time, but my battery was fine. I got a white one I havent rooted or nothing yet and battery is going fast. I kept the battery from the previous phone. I was looking through appbrain and seen the app "bad ass battery monitor" and my kernal is killing my battery as of today.

Argghhh Bricked it!
Tried going back to Gingerbread and hard bricked the phone! 5 years on android and four different phones and this is the first time I really truly bricked. Blue led on and not a thing else.
Well I guess getting a new phone is one way to get back to Gingerbread.... For now, I'm sporting a cutting edge Blackberry tour!

Why is this phone so easy to brick? I've had 4 other Android phones and I see more bricked posts for the e4gt than all the others combined...

Before the ICS leaks, this phone was virtually unbrickable. Once we get the ICS source and the recovery issues are sorted out it will be that way again. If you stay clear of wiping individual partitions and follow directions in OP you are safe

Mine has been horrible and have no idea why. I haven't changed apps or anything from previous installs or settings but Android OS loves to eat 50% of my battery which is a good 25% higher than normal.

Battery Drain Problem

So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

No its not just international and it is cell standby using almost 10% battery

Ariel 2.10 fixes everything!

I just installed the standby fix and im going to test that and see if it helps. If that doesn't work I'll try the other roms everyone has suggested. Will take a little while to make sure whats good and whats not though. Thanks for the advice.

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.
Sent from my SAMSUNG-SGH-I747 using xda premium

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?

I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

This is it !!

I am extremely frustrated. My phone has always been bad with battery life. Its been over a year or so that I have not seen my phone last longer than 5-6 hours. I am constantly looking for any chance I get to charge my phone. My life revolves around checking battery %age and plugs to charge. Smart phones were suppose to be helping us, but its like they are using me to feed the juice every chance they get.
My T989 is a "SMART" phone with
- lowest on screen brightness (and a screen dimmer overlay)
- no NFC
- no haptic feedback or keytone sounds
- No animations or graphic heavy launchers
- dont play games any more
- turn off 4G/data anytime I get a chance
- No GPS
- Manual Sync emails, facebook and whatsapp
HELL, I want to go back to the age of Nokia's where the batteries would last you through weekend and still some juice left even after it goes through laundry.
But that is not what I am here to complaint about.
I would like to know what ROM+Kernel you have and how much battery life you get ? (w/ screen time)
Who else is going through these ?
Note: Currently on JB stock and a new OEM replacement battery

How often are you using your phone? It uses a lot more battery when the screen is on. You can get over 24 hours of battery life by not touching your phone at all/no apps running.
I think most people average around 3 hours of display time without charging. Check in settings/battery/display.
I'm running AOKP and depending on how often I use my phone it can really deplete my battery.

I've been running CM 10 for awhile, and I've been getting great battery life. Recently It's been sliding, and it's due to my battery just being old. I've got a new one I'll be putting in tonight. Get Gsam Battery monitor and check out what's using the battery.

easiest way i have found to extend my battery during the day is to toggle my data..if i am not using it for a bit, just toggle it off, takes 2 sec to toggle it on, and can easily double my battery life..

I use Jedi mind trick with Tiberius kernel. It fly's and I get around 12-14hrs with 1hr and 30mins or so with Facebook 1hour and half of music and texting. So get it!
Sent from my T989 doing Jedi Mind Tricks

Do this stuff and read it carefully. And yes 3 to 4 hours is about average screen time. Makes no difference discussing total battery time. You can kill it 3 hours from a full charge with continuous use...or it can last 24 hours....all depends how often your using it and what you are doing with it.
If you go thru this other thread and follow all of the advice ....you should be fine.

These are my results, after buying the LAZA 3800mAh battery. I just had it for one day and it is light years ahead of the stock battery. I don't use NFC, and my brightness is all the way down. (Still I don't believe the brightness is low enough, seems too bright). I am a student so when I'm in class I can't obviously use my phone, so that is why the screen time is below what you guys expect. Still this battery is legit! I got it for $23 shipped (Amazon Prime). On the stock battery I had to revert back to ICS, but with this Laza battery I have no gripes on leaving it on the latest CM10.2 (4.3.1) and letting it go on Dual Carriage (DC, HSPA+42) mode. As long as I leave school with more than 70 percent battery like on my HTC Sensation, I am fine.

I do have GSAM battery monitor installed. I had it installed since it was called "bad ass battery monitor". It always is consistent and shows that screen uses most battery (abt 35% of overall usage), even at lowest setting. I also have a screen Filter app https://play.google.com/store/apps/details?id=com.haxor That overlays on the screen that dims it even further and is believed to save some more battery.
The other major user is the apps which is
- Android &
- Kernel

I will try the cpu spy again. I remember doing it before and it was almost inconclusive if there were things I could control vs system related drain that I couldnt control.
I am currently on a new OEM battery (2 months old) and several ROMs later,. Some ppl claim they get best battery life, I just want to mirror exact same ROM, kernel... even the apps they have and their refresh settings if I need to.

Dude.....less than an hour screen time tells something is very wrong.
First...I would bet the screen dimmer app Burns more battery than it saves.....that'd be my guess.
Second....flash a fresh rom, or stock. Run it at least a few days as is. With only gsam and cpuspy installed. Nothing else. I know you may really miss some apps....but its the only way to see if its an app, or rom, or hardware.
Then off gps after your install. Its on by default and is a huge battery sucker.
I'll bet things will be greatly improved. Then install apps.....monitor closely for changes in gsam or cpuspy.
Your screen battery usage should be more like 60 percent or higher....even as dim as it goes. That's normal. Apps, maybe 30 percent and then the other stuff. A 35 percent battery drain from the screen says you have problems.
After all your apps are installed.....try everything in that link I posted. Everything. And things should stay good.
Keep us posted.
