Hey,
I just got my new Samsung GT-I9300 international version.
I have the XXALF2 Build, I didn't install much apps at all (Temple Run and app built by me).
I drained the battery until the end - then charged it to 100%.
I synced only my google account, and I have weird batter drain when wi-fi is on and phone in sleep.
Every something around 10 minutes the battery drops in 1%, and it's very weird because on my Captivate, if I let my phone stay with wi-fi it was about 2% every hour which is pretty normal.
When I look at battery stats I see Cell Standby with something like 50% and I really don't know why.
I got my new micro sim today and yesterday the phone was without sim and with wifi and still drained battery and showed high cell standby.
Should I make some kind of calibration on my battery? Is someone else having this problem?
Thanks in advance,
Elad
This is well documented already with plenty of threads as well as a fix. A search will bring you lots of results.
It's actually a reporting error and not really draining your battery. It's been fixed on the newer firmwares.
You'll need to dig further to find out what is actually draining your battery. Given it's still new it'll probably settle in a few days.

Yes, I found the fix of the xml file in the framework. I'm really sorry for not searching before, my bad.
But still, is there something that drain the battery because 1% every 10 minutes is not good at all. Now I see Android System right after screen.
I didn't installed anything yet, so I'm afraid to think what will happen in the future when more apps will be added.
Do you have some recommendation of first steps I should do with the new battery?
Thanks
To see if it's wifi related, at night switch off wifi and test. Maybe even switch off data to see what happens. But as I said, it's still probably a bit early to really tell. My phone took a while to settle. Or maybe it was the custom kernal I installed (siyah).

yerr. just give it a few days. im sure theres other stuff on the interent that can help too
Ok I flashed XXBLG8 and the problem gone! Battery is really great, the phone was on sleep, with wifi off and mobile data on, and only 1% was down after a hour!! I guess the previous build was buggy. Thanks everybody
Ok - I think that the problem is with wi-fi.
With wi-fi the battery is drained very quick on sleep and with mobile data the battery holding fine.
Mobile data suppose to drain the battery more quickly than wi-fi so it must be a bug with wifi.
Really weird and annoying :/

I have noticed my battery sucks lately. I know the battery isn't the greatest but I was able to get easily a day of use out if it. Now I can barely go a day. I purchased beautiful Widgets, battery indicator and xda app all last week And it seems after that is when my battery went to **** .I used launcher pro for a bit too but started having lag problems so I removed that. Today I uninstalled beautiful Widgets. I'm on wifi and in airplane mode. As I'm typing this I've lost %2 already. Wtf is going on? I have GPS Bluetooth and usually wifi off. I have use only 2G networks, sync only gmail and screen manually set and set to low 30sec TO.
Any suggestions?

Sounds like way more than that. I can certainly type a couple paragraphs before my % drops at all. You sure haven't installed something else? If not you could have a defect.? Possibly return it and get a new one?

Quick question, which ROM are you running? Ever since I switched over to leaked JI2, every couple days I notice that after running one of a few apps, the CPU just seems to go into overdrive. The phone gets really warm and the battery drains ridiculously fast. So fast that even plugging into my car charger won't charge the phone, even on idle. If I reboot, the phone cools down and the battery drain goes back to its normal, slow self.
I haven't narrowed it down to any specific app yet, but it seems to be either, Foursquare, Great Land Grab, or Bubble Blast.
Foursquare I have, I don't remember when I installed it. I am actually just running stock TW.

I get 15hrs... I am not ROOTED! I did the drain battery life process twice. This is with moderate usage. I am planning to do the drain battery process once a month cuz I hear it helps with battery life. Possible that u install something that's killing your battery.
Solution do the master reset if that doesn't help then it can be the battery is no good. I know that this is with the stock rom. If u are using another rom that's maybe the problem. U can try switchig roms to see if this is the problem. I hope this information has been helpful.
Does the master reset remove everything ? I have all my pics/videos on my phone meM. I have music and avatar on SD.

I have all of those apps except for battery indicator. I get about just over a full day. I would say turn off Wifi Sleep Policy and see if that helps.

I've had it installed for a while But started using it as of late. GPS fails all the time now though for some reason. Idk. But its kind of frustrating

I have the same issue and i run system app n it doesn't show anything abnormal running. Its awfully frustrating i went from being good for 18hours to being in the red after 12 hours. I dropped 2% just writing this. I have only 84% left after 1.5hours this morning...and I have no service during my 1hour commute so I haven't used it. Standby is killing my battery.

It seems as though it drains faster in standby with nothing running. I removed FourSquare last night and have nothing running as far as widgets. I'm going to reboot and see. I've had it unplugged since 7am this morning, after a little over an hour I lost 2%.. not that bad I guess..

I've had this happen a few times. For me, it's usually because my battery status gets thrown off somehow. The phone would read that I have 55% battery life left, but it really only is at 25 or 30% and it always feels like it's draining fast. I usually turn off the phone, pull the battery out for a few seconds and then put it back it. When I turn on the phone the battery percentage is corrected and the phones seems to be back to normal battery use. I don't know why this happens.

This was suddenly happening to me today -- my battery started draining very quickly, mostly on standby (I usually have quite good battery life). No new or unusual apps installed in the past week (I don't use Foursquare).
I gave it a power-down/battery pull; no adjustment in the % as described in the post above, but it seems to be draining more normally now. Weird....

Same thing happens to me every couple days. Rebooting the phone fixes it every single time though, so it's not a big deal if I catch it in time. If I didn't catch it, I'd estimate my phone would be drained (even in standby) within 4 hours or so.

Same here, I rebooted after removing FS and some other apps/touitur and got 1day 13hrs on the next charge with pretty moderate use. So whatever it was, it's gone now. If it was FS hopefully it's fixed soon.
Had a similar experience, with battery % entering freefall every time I turned the phone on. Two things helped:
1. I did the drain cycle. Drain the battery completely till it shuts off and charge it to full while off. This does not 'fromat/form' the battery in any way it just helps the phone to calibrate the meter.
2. I uninstalled few apps that I suspected were draining the battery.
I advise you install JuicePlotter and see the graph of battery drain. You'll be able to tell if the phone is entering standby or not. Thanks to some culprit apps (still figuring out what it was exactly) my phone was not entering standby at all hence the crap battery life.
Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Since the JB update I have been trying to narrow down the culprit in battery drain that has cropped up. Going through better battery stats there was never a definitive clue as to the cause.
Tonight my phone has been off charge 3 hours and its drained 10% in battery sat on a shelf doing nothing, simply because WIFI was enabled.
One of the stand out features of this device was decent battery life up against comparable handsets, now that's been taken away from a shocking firmware update i'm considering jumping ship.
Has anyone else found any means of fixing this yet? Or just a case of waiting for Samsung?

Theres some threads talking about this.
I don´t feel that.I´ m on LJ5 build and sincethe LJ builds I´m very happy with battery drain, even sometimes I get 5 hours screen on with wifi on.
Maybe you update your phone from ICS and don´t wyped your data or made a fresh install. Try to do so and you should be happy again.
It's probably due to a dirty WiFi network that's smashing a bunch of multicast packets. Pretty much all the custom kernels available now have a patch to ignore multicast when screen off; otherwise you'll just have to wait for Samsung to realise they did something silly (read: never)

That makes sense. Always the same with Samsung, takes them an age to get a new software update out and when they finally do it always comes at a cost.
My battery drain is less after settings in advanced to always on and changing the location settings and turning off notifications in some apps and also in play store.
Also in maps automatically update your location might be a battery drain.
I've got a lot of battery drain with wifi on, too. Last night, my battery dropped from 29% to 0% (in 5-6 hours) with wifi on. I woke up to find that my battery had been depleted. UGH!
Must check what is draining your battery. I don t experience that... so far and from many android devices I ve the s3 is by far the battery frindly I have.
I i ve s2 and xperia neo dayly use and I'm happy. I use also some dirty wifi networks and don't have problems at all.

it's a known issue on latest JB rlses. Whats funny is that :
-The leaks did not have the wifi battery drain
- The wifi drains more Battery battery than 3G. I can have 3G on all the time the phone last up to 1d10hrs with 2hrs screen time
I'm on the leaked version. But on lj5 I didn't experience that so far.

Iv had my galaxy s3 for 5 months now and i dont know if its just the Jellybean update but the battery drain when having wifi on is really bad im lucky to get 1 days usage with the phone , i got my google nexus4 yesterday and iv used wifi and data for most of the day and im now in day 2 my battery is at 44% and both batteries are same 2100mah
think im gonna sell my GS3 as the google nexus4 is so much better with battery , but before i do i will reflash stock jellybean on GS3 without root and run them both side by side to compare results , but so far GS3 battery is real bad for drain if i install juice defender on Nexus4 im sure i would get between 2-3 days usage with moderate usage
i will run my tests on both phones side by side with and without juice defender and try to show
I have had the same issue. Though the battery drain is not drastic, it certainly is more compared to ics. If you require better battery life then go back to ics and flash Aosp/Aokp roms

first question, what do you mean by extremely fast? unless your phone is dieing in under an hr from full charge i wouldn't say its "extremely fast".. secondly there is a "discussion thread" located in the general section of the forums to talk about and find solutions to problems related to CM 10 found here, also have you checked your battery stats to see what is eating your battery away? weather its screen on time, cell standby, wifi or data... or an app.. there are several issues related to battery drain.. like if you have wifi on but not connected to a wifi location.. or having data on but in an area with no signal.. more information is needed but i would prob suggest to do a full charge to 100% wipe battery stats from recovery and then do a test from 100% to see how long your phone lasts with full usage and in full standby mode... then compare and see what is eating your battery life away...if not refer to the thread i liked earlier up in this post

My suspicion is that Google now prevents the phone from sleeping normally hence affecting battery life in standby mode. However if its dying in under an hour that is quite drastic and I would suspect there might either be a rogue app running in the background (do you have the eBay app installed? I found that also contributed to awake times in cm10). Second question is how long did your battery last in speed rom? Were you getting at least 2 hours of screen on time? If you got less than 1 hour and 30 minutes of "screen on" time in speed rom with data not constantly on I would suspect your battery is failing as well. Good luck

Try a different Rom, is same experience, i recommend a new battery.. Battery can wear out over time..
Hi xda! So I've been having a problem for a couple of months with my SGSII and i have searched a lot but i haven't found a solution yet.
The problem is that battery behaves normally and has a normal drain rate, but when it reaches 40% more or less it drains massively and drops to 10 % (more or less, could be 11% or 9%. It is not something precise and accurate) and screen immediately starts to flicker, backlight as well, then the signal is lost and phone shuts down. After that i can not turn it on unless i charge it.
I have looked a lot and pretty much all of the forums recommended to buy a new battery. I bought another battery (original) and the problem still continued. I've also tried swapping batteries with a friend, but the problem still happened to me and not to him. Also I have tried a lot of Roms, I've tried going back to stock as well, but still nothing.
Currently I'm running Cyanogenmod 10.1 RC2 because it gives me the best battery life in those 60%.
I leave you an attachment of a screenshot. As you can see battery percent dropped a lot at the end, and i wasn't using it heavily.
Thank you in advance.
It is a hardware issue, I had the same problem (battery would drain below 10% though), sent it to Samsung, Motherboard and Charge Socket got replaced, I don't know which one was causing it because I had other issues like broken home button too.

May be there would be some hardware related problem. But why dont you give a try to to a wakelock detector app like betterbattery stats or wakelock detector? Atleast you will know which app is eating your battery or is it a hardware related problem.

It is a hardware issue, I had the same problem (battery would drain below 10% though), sent it to Samsung, Motherboard and Charge Socket got replaced, I don't know which one was causing it because I had other issues like broken home button too.

Thank you for answering. Unfortunately I have already rooted my device hence voiding my warranty. Maybe i could have it fixed by some technician.

I have tried a lot of battery related apps. BBS is one if them. I haven't seen anything unsual. In fact I've also tried apps like greenify. However battery life in the first 60% of battery is actually good. After 40% comes the problem.
Send it to samsung
