So I rooted the phone and installed UltimaRom v11. Now the battery is draining like hell...I solved the issue of the charging (since it is a hardware stuff, that we need to charge with a wallcharger, yara yara yara), but the draining issue is a PitA.

usually fast battery drain is related to kernel, modem or media-scanner issues.
first try to install other kernel (maybe stock). and check your phone for media scanner wakelock problem.
THANK YOU for giving me an idea at least. I'll try to change the kernel to stock, and how the heck can i know if its a media-scanner issue....
sure, no problem.
for media scanner thing check this thread.
basically, you can find out if media scanner is using up your CPU under "Partial Wakelocks" tab in BetterBatteryStats.
I don't think it is a rapid battery drain. From the screenshots you have provided, your phone has only been up for 28 minutes. That being said, the percentages of your wakelocks are based upon how long the phone been on battery; i.e if a wakelock is 20% and your phone has been up for 100 minutes, that wakelock has been occuring for 20 minutes. From what I've seen, after a boot, the S3 tends to go crazy for a while, various wakelocks happen, and after 30 minutes - 1 hour or so, the wakelocks settle down and come to a halt. Then the percentages go down, and soon becomes only a tiny number later on.
Here's an example: PowerManagerService wakelock is showing 80% in BBS after your phone has been up for 30 minutes. 30 x 0.8 = 24 mins (How long the wakelock has been on for. After 2 hours (120 minutes) if the wakelock has stopped, it will only show up as 20%, because the wakelock only has occured for 24 mins, which is 20% of 120 mins. As time passes more wakelocks will occur and then we can see which ones are the real problems.
Provide us with a screenshot after your phone has been running on battery for about 2-3 hours or so, or just before the juice runs out, for more accurate results/replies. Hope I helped!
Let's see now.

My SGP5 battery has been wacky since day one. First few days I didn't think it would charge past 80%, but I found if you charged it overnight it would hit 100% (that's after an 8 hour charge to 80%).
Today it showed 100% all day. I booted it and now shows 30%. The settings battery status does not show actual time on the lower scale. Like I said I was at 100% all day, and the chart goes up to a 100% peak, but doesn't flatten or go down.... as if the battery clock stopped (not there is such a thing).
Can't do a battery pull... could rooting solve this issue? At least you can do a calibration with root. I just don't want to root if this will be fixed in an update. But I really don't like not really knowing how much battery is left.
I have a similar issue. It seems random- I use it all the time and literally 1/2 of the overnight charges I put it through it gets to either 80% or 100%. What I've noticed is that even when it says 80%, it still performed as if it was fully charged.
I rooted my device a few days after I got it and I honestly didn't notice the issue until after I rooted my device. So it may be different for you.
I'm not rooted. Have you tried something like: http://www.appbrain.com/app/battery-calibration/com.nema.batterycalibration or manual calibration deleting the battery stat file? I'll gladly root if it solves this problem.

To show how squirrely battery charging is, I monitored with Battery Monitor Widget and looks like this, one charge overnight without unplugging:
(each grid line is 1 hour, little over 1 day shown, screen was NOT on during charging)

So, I'm using the newest stable release of CM9 with Siyah kernel and my battery life is terrible. Not even using the phone for an hour, eight hours of standby, and it's already down to 30%. Any solutions?

Most battery drain issues are user related, check your apps with Better Battery Stats and install cpu spy for sleep time of the cpu. Might be some rogue stampeding apps/widgets on your phone
As you can see on attachments, my battery stats are equal... my awake time is very high, and i have better battery stats installed, it says my cpu time are 90% into 200mhz mode, but as you can see 15% with 13h of usage... but doesn't show any application draining my battery...
Anyone know how to trace this correctly?
Battery probs
Hi mate! Its mi first post i hope they will be no errors!.
I had the same prob as u and i did this:
1-Install ---> Battery Calibrator ( root need ) from googleplaystore.
2-Charge it to 100% REBOOT YOUR PHONE (program dont say a thing about this
3- Press button , all your battery stats will be correct now
4- If u continue having this probs you have to Re-boot your ROM and do all this steps with 3 wipes

You are using siyah?
Make your cpu 1200-200 or 1000-200
Overvoltage 50
And you will see the difference.

I found that Friendcaster for Facebook was giving me wakelocks. BetterBatteryStats is a must-have.
Hi,
I have been using the same ROM (cm9.1.0) for about a month now, and just yesterday I realized I was getting horrible battery issues. Nothing has changed recently so I'm very confused. When I look at the battery option on settings, I see the phone process taking 62% of the battery life (when you first open the screen it's called sec-ril then changes to Phone), compared to the screen which is at 15% and everything else which is at 4% or less. Battery life is absolutely horrible now for a reason which I don't understand. I am using UCLF6 on 4.0.4 but I don't know what would have caused the recent change. I would post a screenshot but my screenshot thing is apparently not working at the moment. By clicking the phone process it says "CPU Total: 3h17m14s, CPU foreground 1s, Keep awake 2m 34s, Included Packages: SIM Toolkit, Phone/Messaging Storage, Phone). It may be helpful (or not) to know I have probably used the phone for 10 mins or less the whole day and all of the texting I do is done through Google Voice (as well as most calls).
Thanks if you can provide any help.
I think its obvious you have apps keeping your phone awake. That one was a real head scratcher.
can someone tell me how to fix this all I did was make one phone call that was less than one minute and didn't do anything else and this happened

Try rebooting your phone first and see if it persists. Then repost your battery stats by kernel wakelok.
from a galaxy far far away....
I have started seeing this(sec_ril process draining my battery) too. Sometimes only. Did anyone figure out how to fix it permamnetly.Wiping caCHES fixes it for a few days and then it comes back. I install nigtlies by wiping everything including internal sd card
I just had this start on me within the last day, day and a half, Phone is using 100% CPU forever. Rebooted, checked APNs, etc... Going to try clearing cache although AFAIK that has nothing to do with such things, might try reflashing...
Well, I don't mind eating words sometimes. I had rebooted a few times which didn't help, but wiped cache in TWRP and sec-ril has stopped its nonsense.
Mine started doing this a day after installing CM9.1. I literally have nothing installed on my phone. 20 minutes of usage after being fully charged and it's down to 83% battery, with "Phone" using up 61% and Screen 23% (I'm on minimum brightness). Wth :/
The problem:
Lately, well it's been quite a while actually... my battery stats seems to jump whether i'm charging or discharging.
While charging sometimes it jumps from 30% > 80% > 100% within 15 minutes (this is what happened today) while discharging, it jumps from 90 > 50 (this quite often) then to 20% > 5% then off. My max usage time without charging is usually less than 1 hour.
I've tried to do battery reset (charging while the phone is off until full, reset battery data, then use it till it 100% drained)
I've tried to charge from 30% to about 80/90% then use it as usual.
I used original charger from motorola, used blackberry charger, samsung charger, no difference.
Unfortunately no good. Currently the ad hoc solution is to use battery powerbank constantly while I'm not near electrical plug. But its bulky and well not the best solution.
My question is, does the problem lies in the battery or at the battery controller. Is there anyway to test where the culprit is?
Thanks in advance
Battery daemon Moto uses is imperfect in calculating the battery percentage.
However, the jumps you experience and the backup you're getting, looks like your battery has worn out.

Hi, thanks for the input. My question then, will replacing the battery help to solves the problem? Cos lately the battery stats seldom runs over an hour. Here's a screenshot of my latest battery stats...

Your battery is definitely worn out. Replace it.
A new battery will certainly remove the issues..
Use the 10% mod though else you might still have infrequent jumps..
Hi, I know there are already many threads about it but I think I have a slightly different problem: while charging the phone is always active (as if he was doing something in the background) resulting in an extended charge time.
First thought: there must be an active process (developers opts-> show cpu usage) and ... nothing
Second thought: maybe "dmesg" can tell me something more and...
...well, that seems something

The "adc" value of the battery significantly increases when connected to the wall charger, so even if the "adc_chg" value is high it is compensated by the high drain of the battery.
Am i wrong? Has someone any idea about the cause of the problem or about how to find it ?
Thanks (going mad, yet changed battery, charger and multiple USB flex ports )
You do know that our phone never deep sleeps when it is plugged? There is a specific wakelock for charging, which will keep the freq to 200mhz. As for battery drainage, nothing much can be done because our phone's charging capability is not advanced compared to newer phones and hence it is easy to drain the phone battery even when plugged. Doing simple things like closing all unused apps, keeping the screen off, turning off Bluetooth or WiFi may make the phone charge a little faster.

I did know it, it was stated somewhere in the previous threads. What I forgot to mention is that, actually, I'm talking of an s2 with Greenify activated, no third party background process admitted except Telegram & Whatsapp services but charging in offline mode, screen always off. And still says it will take 2h 45m when charging starting from 65%, math can be done for when starting from 1%.
Time ago it only took about 1h 45m to charge completely, so it seems strange.
