[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.

I'm not sure. But that's why I recommend moving it, so you can always reinstall it later if you need to for any reason.

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 life issues? Try this.

I just got my GS3 about four days ago.I noticed just like many people out there, that my battery wasn't lasting as long.After some research I found that doing a factory reset solved the problems.I'm getting 15+ hours now with moderate to slightly heavy use. Before I did this my battery would lose 40% with very light to moderate use in about 1hr 30mins.
No root.
Settings>Back up and reset>factory reset>wait for reboot>set up phone(just the initial setup)>turn off>remove battery and reinsert>boot back up (this is what I did)
How my phone was setup(sync,use etc.)
This is without power saving mode.
GPS: off
Wifi: on,because I havent gone out much these last few days(but off when I do)
Brightness:No more than 20% usually at 10%
I live in a LTE area just in case.
Moderate texting.
No gaming.
1 Call for about 30mins.
Moderate to heavy browsing.
Skype call for about 30mins.
Bluetooth: only on during 30min call.
Apps that sync:
Scope:every hour(syncs tumblr and facebook)
Facebook:every 2 hours
Weather:every 6 hours
Google account sync is on.
Email syncs once a day.
I barely receive gmail so I only get a notification from it once or twice a day.
During the night my phone lost about 14% (45% to 31%).
DISCLAIMER:I CANNOT GUARANTEE THIS WILL WORK EVEN THOUGH FOR A DECENT AMOUNT OF PEOPLE IT HAS,DON'T BLAME ME IF IT DOESN'T AND FOR THE TIME LOST IN YOU TRYING THIS.
Its still good to give it a try.

thats sad as heck man, you ruining a good phone doing all that, either man up get a new extended battery or root your phone and undervolt that crap.

This is just for testing. As it would reflect my "regular" use.

You have a wake lock your phone never sleeps.

See the awake bar on your battery screenshot? That means your phone was on all day and night; it never went into deep sleep mode. When your phone is awake it uses practically the same amount of battery with the screen off as it would with the screen on, minus the display usage.

Yea damn thats a lot. Also the auto update apps, just turn those to manual. No need to get Facebook stuff every 2 hours when you know you'll check it sometime during the day. Same with weather.

This was just for testing purposes I understand that without all that the phone would last much longer. But its a GS3 so I wanted to see what it was capable of. My thinking is if it got 15+ hours with all those things auto updating imagine without.

I lose 1% an hour in standby. Maybe slightly less. Tuchmi with faux. Samsung garbage removed.

That whole post is pointless.

Charging up while phone off to see if there's any battery improvement.

Still doesn't solve your wake lock problem. I would get on that or you will continue to get poor battery life.

Strange thing is even with the wake lock it got 15hrs. Shouldn't disabling the auto updates solve that? If not I think the wake lock was due to the cell standby bug.

It should still sleep unless you are constantly updating every minute you have something else going on. Cell standby is just a measurement bug. Even if you patch it your battery life will be the same. When I let mine go without charging I got the same screen time but over a day between charges so you are losing probably 25% or so from it.

Horrible Battery!
Rooted my SG3 and have noticed a large battery drain. Unplugged from charging to a full charge and left phone off and it sat on standby mode. 3 hours later after NO USE it is down 20%. This doesn't seem normal. 29% is due to cell standby and 25% is android OS. On Wifi at home too, so I don't think its struggling for signal. Any ideas?

battery life

hey all, recently my g3 has gotten terrible battery life, when it would usually take me through most of the day, it now only gives me like MAYBE 12 hours with less than 2 screen on time. today, i pulled it off the charger at 1230, by 4 it was down to 54%, and after 8 1/2 hours of sitting(i was at work) it was down to 15% and then it was dead less than an hour later. i'm unrooted(was rooted) and on the latest ota, i've done a factory data reset, re-rooted and unrooted and another factory data reset. it's just weird to me because about two weeks ago my husband's g-flex wouldn't hold the data connection, dropping in consistently for two weeks(bad enough that t-mobile sent him a replacement unit, and eventually put him in a note 3) and all the sudden my battery life went from decent, to complete crap.

You are having some major wake locks. Check your apps for "kept awake ". Usually Android os has a big number but dont worry about it. Here are my battery stats for reference.
Let us know what you find out and post screenshots of any abnormalities.
Edit: ive had bad luck with battery logging apps draining a lot of battery and not letting the phone go into deep sleep.

23 hours and still at 77%???? Is that with phone just sitting not in use in stand by?
Sent from my LG-D851 using XDA Free mobile app

Here is mine. Bluetooth is on from the time I unplug till I plug it in at night going to bed. Wifi is off during the day, so I'm on 4G LTE till I get home and turn data off and wifi on. So wifi is on for about 6-8 hours a day. I always typically keep sync off. Ill turn it on a few tomes throughout the day for a few mins to pull any emails and what-not, than I turn it right back off. It drains a lot of battery on mine just talking with apps trying to pull data from them constantly.
Location is also usually off until I need it. Today I had it on all day.
My screen brightness when I'm away from home is usually anywhere from say 60-95%. I HATE auto-brightness, just keeps it way to dark.
I also use greenify, and I have clean master auto clear memory upon screen off. So when I turn screen off, all apps I selected hibernate via greenify, and memory clears with clean master.
I'm also using trickster mod, and have a few kernel tweaks to smooth out the notorious G3 stutter which was from a thread on here. Lag solutions I think(ill grab link in a min) via Heisenberg's settings. Very stable and runs like a champ!
I am using g3 tweakbox, nothing fancy going on though or crazy.
Also, I do have seeder, which I was using before the trickster kernel tweaks, and it was working great, but I'm trying the trickster settings for now.
I HIGHLY recommend using the trickster mod kernel settings heisenberg suggested in his his thread. They are extremely stable, it makes phone snappy and very smooth, and I swear it made my battery life much better! Give it a shot, I swear you'll love it.
Here is lag solutions thread, 1st post is the kernel tweaks I use w/ trickster mod. It did help battery. Give it a shot, if it doesn't help you, or makes things for(which it wont, its very stable) you can always undo them just as fast and easy. Do all of them though, and do exactly, don't change numbers yet(if you're very comfy with it and do k is what you're doing with it), just give those a shot.

Thats a medium/light use with mostly talking on the phone and listening to music day and i have a follow-up for it. The pics are after 48h of use without charging.
Coming from a Samsung galaxy s3 im really impressed with the battery on this phone.

How do you have less screen on time after 48 hours than you did at 23?

Because that screen shot of the screen on time is from a different day. You can see that if you look at the time/date and battery %.
Sorry about the confusion.

Hows your signal strength? Having crapy signal drains the battery a lot.

didn't even think to check it...you'd have thought that would have been my first instinct with the issues my husband was having with his g-flex...but, battery life was my only issue with the phone, and it's up to where i'm content with it now, but in answer to your question -87dbm

Ok so I did a "test". I had bad signal- 1 bar 4g and it would hop to 2g quite often. In about 2h i drained 70% battery with tune in radio and the screen turned off. I couldnt screenshot it because my phone died :banghead:
My guess is that if you are working somewhere with crapy signal and you have push notifications coming in often it would kill your battery.

[Q] Battery drain when idle

Hey guys,
Wanted to know what your experiences with battery life were like.
When I go to sleep, I switch off wifi, bluetooth and data. When I woke up after 8 hours, the phone had lost 7%. Seems to be quite a high number for it being dormant.
In battery settings, the 'Phone Idle' option was top of the list for battery drain.
Anyone else experience battery drain here? What have you done to help improve it?
Cheers.

What's your reception like?

Install better battery stats or some wakelock app and see what's keeping your phone awake

Don't you need root to use better battery stats? Phone hasn't been rooted yet.
Signal strength is decent, not full bars, but close to it.
My last 2 phones (N5 and OPO) have had really good drain whilst dormant, so puzzling as to why this one is playing up!

My vzw was similar. About 10 hours of no use and was down to single digits.
Did a factory reset and it was better... Teach it who's boss...

Last night my phone was off the charger, at 100% to begin with, at around 2 am. I checked it at 6 am and I was still at 100%. For me, idle power usage has been very low.

Ya you need root. Goto WiFi settings then advanced and see if the 2nd option is on, (its something like apps scan for network even if its off) turn that off. If you want to stop Google play services from waking phone from privacy guard that helps a lot too.

The other thing I did (not sure if it is related) was to disable all the VZW apps and processes. WHen I did that I only lost 13% when left over night and I was down to a respectable 73% after a full day of work (though I intentionally did not use my phone much during that time)

This phone sleeps unbelievably well, better than any other phone I've owned. It flatlines very nicely

I did not manage to factory reset the phone overnight, but I did notice that the battery life whilst sleeping was incredible.
Over an 8 hour sleep, I had dropped 2% battery life. I switch data and wifi off when I go to bed. Now I'll keep an eye on SOT. Hoping to hit the 4hr mark. On my first few days, I got 2.5 hrs.

Even I Am experiencing same problem. Any one plz help

I have the International H815 and I have the same problem. Battery drains too much on idle. When I look the battery stats the Doze mode rarely kick ins. Location is off Bluetooth off and I'm on wifi. When Doze works I have really good battery and I can hit 4h of SoT when not I can barely hit 2.5h of SoT. This must be some kind of bug. Phone does not goes to sleep and Doze rarely kicks in.
