I use SystemPanel to monitor running processes on my phone. I recently installed SimplyHoney 3.9 with a Bullet JVP kernel. It was working great for a week or so, but now all of a sudden I am noticing that my battery is dying. Fast. Really fast. So I went to check SystemPanel to see what was hogging up my CPU time. That's when I saw that my CPU was pegged at 100%, and that the SYSTEM process was responsible for about 80% of my CPU time over the last 8 hours, and that it was often times running at 100%.
Rebooting doesn't help. I was thinking about reflashing, but I am pretty doubtful that will help. But you never know Anyway, is there a good way to see exactly what in the system process is misbehaving?

Download Android Assistant from the Market (it's a free app), go under tools, and look at the Battery Use section. Should let you know what's causing the battery drain. However, if you tend to use light or white wallpaper, leave your phone screen on a lot, and at max brightness, your problem isn't software related

If you have ever installed the current widget on your Thunderbolt, I just wondering how is the number when the phone is left standby. Please share here, I am looking forward to see the result. Just average result of current widget if you leave your phone to standby mode.
If you root your phone, please mention that you root it. In case it makes different between rooted and unrooted.
Beginning from me.
My average result is 36 mA without root.
Thanks before.
38mA rooted

How are you drawing more current from a rooted phone . 4g?
I'm down to 11mA idle power draw on ginger bread. They made enormous improvements on idle power on 2.3. It's excellent, I'll go hours without losing any battery of idle time. Finally.
34mA basic root with bloat removed

Sorry yeah, my nexus one actually. Just wanted to help compare how improved ginger bread will be when you guys get it.
Just today I have been unplugged for 15 hours and still have 71% battery left, connected to WiFi all night. Granted this was idle use, but it was never this good before. I exported the logs and idle current stayed level at about 12mA the whole time. My idle power on froyo stayed around 30-40mA no matter what I tried. I'm happier than I've ever been with android right now!
Something for you guys to look forward to.
I wish the carriers would realize that most of us want the ability to use the lastest greatest rom as soon as it hits and would quit locking their stuff down. If nothing else, I would think that google is big enough as an OS to tell the carriers to stop using their OS or leave them vanilla. I mean for a company like moto, who are they going to use? WM7? please. Sometimes a tiny bit of force is needed.
I am at 60mA. What gives? My battery dies in the middle of the night every night. I am rooted.
26mA here, stock.
I must be doing something wrong, mine says 180mA.
It makes a difference if a) you're plugged in (in which case current is showing you how much charge you're getting, not current usage), and b) if you're using the phone (tip, turn off the screen, let it sit for a minute, then check).

Right. The best way to check that I have found is using the history button. Put it to sleep then wait a half hour then check the history. I set mine to update every 5 minutes.
I use Battery Monitor Widget:

I noticed that most of GingerBread build consume less battery. Right now, I am still looking which activity drain my battery.
I know battery has been diacussed before but i think this isnt normal. I left the office with almost full charge, listened to music on the.way with bluetoith headset for an hour. Got home and browsed for like half an hour. And here is my battery.
3 hours and the phone is almost dead. I have no apps running. I had 3g on when i left the officw and at home i used wifi.
Is this normal or should i take the.phone back for an exchange?
Regardless, i still love the phone.

btw when u return the phone what do u say exactly
Thats ridiculous man. Maybe you're battery is broken.
That said mine has just drained 35% in 3 hours with almost no usage so maybe it is just the phone.
I think there is 100% guaranteed a software problem and we need samsung to fix it.
It says you've had the display on for quite a long time, music needs the display on? Also that wifi sharing is another culprit.
It drained because you had the screen on nearly the entire time not because anything else
Unless thats a case of the 'phone staying awake' bug. You can freeze wifi sharing with titanium backup to save some juice

I too am facing the same issue battery drain from 100% to 60% in a span of 3 hours.
I am having a mediocre usage of battery with touchdown as my mail client talking to my corporate exchange. Still it doesn't warrant a drain of 40% in 3 hours.
I dont have much apps installed. Even with juice defender I am not getting better results.

You could say it's normal because if you haven't yet rooted and frozen the wifi sharing process this is the exact behavior everybody else is also having. A new phone will behave in exactly the same way if it's using the current firmware.
You can do two things.
1. root and freeze the process with titanium backup or similar.
2. wait for the next official samsung firmware which may include a fix.
The rooting process takes about 15 minutes and is not too difficult. You may or may not get in to warranty trouble in case of repair, but as I and several of my friends saw it, there really is no other way unless you want a phone with 3-4 hours of battery compared to the 19-23 hours we all get now after the freeze.
Another thing, it won't matter if wifi is turned on or off, the bug and wifi sharing process will still be there.
You will probably read around the net that several processes has to be frozen, but it really only is the "wifi sharing" one that needs to be frozen for the battery drain issue to go away.
What is the "wifi-sharing"?
Mine GS2 is a bit different from the OP's. Android OS occupied 45% while Display only 19%. And charging time is unusually long. Very long. I plugged my GS2 into PC at 9am with 30% left, and by the time I left work 6pm it only got up to 75% something. That's half a day charge.

I don't really know. But I haven't found a feature not working after the freeze. Even dlna sharing, hotspot etc.. Everything seems to be fine.

Regarding the unusual long charge time, I haven't heard about that before. It takes my phone about 3 hours to fully charge.
I can recommend this application for monitoring if the phone really sleeps when left on the table and which processes uses your juice in general. It's history based and you will be able to figure out a lot of useful stuff with it.

I'm also have a similar problem, but mine was after one hour and an half of web surfing using dolphin HD and wifi... it was full, it's now about 25% remaining... Is it normal that the dolphin browser used 39% of the battery ? It's even more than the display... !
Ps: it's actually really hot on the back of the phone, on the top, just under camera... Normal ? ? ?

Well. When you have rooted your phone, you are able to do a lot of usefull stuff:
-Freeze processes
-Disable the camera shutter sound with a simple property/text file
-Make the middle home screen the real home (like htc sense) with a simple property/text file,
-Replace camera.apk and get higher quality sound in video, actually also higher video bitrate if you want that.
-Replace talk.apk and enable the upcoming google talk with video chat
-Install chainfire3d driver to be able to play tegra2 gpu based games
...and probably a lot more, but above is the only things I've done.
Freezing means : that you lock a process you don't want to run ever. You are also able to "un-freeze" if you decide to revert.
So:
1. you root your phone
2. you install titanium backup or other application that has the "freezing" ability.
3. open the freezing app, go to the process list, find "wifi sharing", press freeze, reboot
Problem solved, "wifi-sharing" will never run again.
You want to revert: Launch titanium, go to process list, find wifi sharing, unfreeze, reboot. Everything back to where you were before.

I really don't think anything matters as I can see you have the wifi-sharing bug.
You must understand, that it's everybody with the current firmware that has this bug. You must either wait or root and freeze.
Sucking up your battery in a couple of hours and making the cpu run at full speed which makes the phone get hot is exactly what this wifi-sharing bug does.
There is absolutely no way you can change anything in the settings or say, not run dolphin browser to fix this problem. You simply have to freeze the process or wait for samsung to fix it. As long as the wifi-sharing process enters your battery usage list you have the firmware that has the problem (and it's more than one) and your doomed until you freeze or upgrade to a future firmware where the bug may be officially fixed.
Just another "wifi-sharing" discussion link:
https://code.google.com/p/android/issues/detail?id=16721
Alright then, it's just that it doesn't seem me to be that much of the battery (~20%...)
I did just freeze that process and will see once my phone is fully charged... Thanks.

oh, was that a constructive comment?
I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?
Sent from my GT-I9100 using XDA App
That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.
Regards.
Sent from GT-I9100
Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,
http://forum.xda-developers.com/showthread.php?t=1179809
Regards.
OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.
I'm using the Neutrino ROM right now. My phone will get very hot after a while, usually during browsing and the battery will drain extremely quick. It use to not do this. I thought it might be Dolphin HD browser I was using but it does the same with Opera mini.
Any ideas on what I can do to fix this? It never did this before and I'm only half way through my day and it's already at 40%. I use to be able to get through my entire work day and still be in the good 60-70%...
I had this same issue when I first got my Atrix and it started happening after I rooted it and customized it. Even after a factory reset, it still ran hot and the battery drained quickly.
I ended up performing a complete factory reset and took the phone back to get it replaced. The replacement worked just fine, even after rooting it and doing the same customizations I had done with the first one.
If you just got it, I would suggest taking it back and getting it replaced with another one. It could just be a bad battery.
My 2 cents!
Here are a few things to help you diagnose your battery drain issue.
Download "CPU Spy" from the market. This program will show you how long your cpu has spent in each of it's various clock states. This program does not reset it's data until you reset it, and your phone's cpu will not sleep while charging. So charge the phone then open the program and reset timers. Now wait a while and check the stats. Your cpu should be going into "Deep sleep" mode most of the time you are not using it. If it is not 75% or more deep sleep after a couple hours, or if it shows deep sleep under unused clock states then you have some condition (probably an app) keeping it awake.
If you have an app keeping your phone awake you need to determine which one is doing it. This can be done by backing them all up with titanium and deleting a few then testing (takes forever,) or by way of another program. I use a program called "better battery stats" from the market, which is a paid app. This app gives you information on wakelocks, partial wakelocks, and processes that are running. It can be used to find the process responsible, which you then trace back to the app that is using it.
I found out about all this when K9 mail was running away with me. It wasn't too bad as long as I was connected to wifi, but while traveling it would constantly use a very small amount of data and refuse to let the cpu sleep. I deleted it and for about 2 months now I get home after 12 hours with 60-70% or more battery life and about an hour of screen time used. My deep sleep percentage is in the 80's every day. My phone is runnign Jokers's cm9 overclocked to 1.45.
Hope this helps.
Try badass battery off market, it will let you see where it drains
Just switched from Nutrino... What version are you using? EE/GT/GT+? I only used the EE because its stock clock speed. I noticed CPU gets extremely hot with slightest OC. Also, noticed quick battery drain while screen was on (quicker than other ROM's)...

Also, if your using the gt+ version with the over clock kernel like I am using, do the phone a favor by keeping the phone underclocked at 1000 MHz instead of 1450 MHz. That will help the heating up too. That's what I do. Battery is great too.
Sent from my Atrix with XDA Premium
As Voelker does, I have the 1.3 version of Neutrino but keep it clocked at 1Ghz max with SetCPU profiles most since any overclock tends to get warmer than I want. I havent had a temp crash yet, it's just me being paranoid sometimes. I do set it to 1.3 when I am playing games for smoothness, but I havent noticed any unusual battery drain, just more heat than I want.
Basically, I installed cm9 RC1, and everything was working great.
Interface and all my apps were working super smooth.
I was getting 4 hours of straight use on a single charge! I was super impressed.
Yesterday, the phone froze out of nowhere. Couldn't get any response at all, had to pull the battery. The cpu was pretty warm too. It has gotten warm through normal use before on other roms, but that had disappeared when I flashed this one.
After rebooting, it tells me the battery is less than 4%, which is very strange since before freezing it was more like 20% full.
Now after this happened, I'm getting literally half the time on each charge. Instead of 4 hours with 15% left I'm getting 2.5 hours and 4% warnings telling me I need to charge.
Any idea as to what is going on?
I'm using betterbatterystats, and according to it, my deep sleep mode is working properly. The apps I use are showing the same kind of usage they did before. I can't figure out what the hell is going on here.
