Just wandering if anyone notice any battery drain while running a few app in the background??
When there no app, battery doesn't decrease unless I use it....but with 3-4 app running, I lose 1-2% in around 8min.
Seem like there is a problem...
It should go without saying that running 3-4 apps in the background is going to cause more of a drain than running a single app. If your cpu has to do more work by multitasking, it's naturally going to require more power and drain the battery faster.
Your not multitasking.. it's freezing processes using onPause as soon as you focus away from it. If something isn't pausing that app is bugged, or "relying" on a background service for syncing or something like that. (That it feels is neccesary to not shut down on app quit).

I've had this battery for several months now and I'm just now starting to wonder why my battery life is so abysmal as compared to others with it. It'll probably last around 18-20 hours a day with about a half hour of music playing through Winamp, JuiceDefender, Lookout, and Tasker running constantly, an 100-800 core clock, and low brightness.
Somehow, I think I should be getting better battery life. It has been similar to this regardless of what ROM I use.
Do you all think it's the battery or just the phone?
Obviously, I'm unable to return it. I would just like to know what others think.

POSSIBLE ISSUES:
(Answering these yourself should help pin point the problem just by re-reading your own answers)
- How "old" is the battery?
- What are your min/max CPU frequencies?
- What services are running in the background?
- Did you have this problem on the stock battery?
- What app do you mainly use?
- Does that app drain battery?

With optimal settings and unnecessary ram hogging apps removed, you should be able to get more hours than that on the original battery half the size.
JuiceDefender should be unnecessary and I found it to inhibit me more than it proved useful.
Lookout is neat, and I do like it, but as I don't see a huge need for it I don't have it installed.
My personal favorite task killer is Advanced Task Killer which I use to cleanup my phone before locking it, you know, close the various apps I just opened . However, I have disallowed it from auto-killing, as this has proved detrimental and in vain when services killed generally immediately restart themselves and consume less battery than the auto killing program attempting to kill them.
A good check on certain apps is to go to Manage Applications under Settings and check your running apps. About 1-2 minutes after a good task kill, check to see which apps have restarted. If any you recognize are running that you didn't start, you may consider removing them. Especially anything that tries to access location services.
Edit: Almost forgot, I don't use any widgets except for Task Killer and Power Control. All others drained more battery than I cared for, and this I tested extensively.
This is my first post here!
So it looks like I may be having a problem with CPU usage and battery drain. My Incredible 2 was fine until this morning when a market update kicked in and started running the whole phone slow, and ate the battery life to 50% within a matter of 2 hours.
I'm not sure where to start with this phone - because I haven't found an app which can give me the list of running processes which are taking the most CPU resources so I can figure out what to kill (or what to remove). Can anyone recommend some tools?
settings>applications>running services. Elixir is a good app also to show you running services. You don't want to be killing apps a lot or often though, just battery draining or memory hogging ones.
Just an fyi...the recent Pandora update to version 1.5.9 to a performance hit on both of my DInc2's. Since uninstalling, performance is back to normal.
Ok - that's good info. The thing is, I never opened Pandora or played it, but I did have a widget on one of my panels (it was never active, either). I uninstalled it, but I can't tell if I'm back to normal yet . . .
By far the best app for this is called watchdog. Amazon had it as its free app of the day a few days ago. all it does is notify you wwhen an app is using more CPU % than it should. It's not a task killer. There's a lite version as well as a full one. I highly suggest it.
And by the way, welcome to XDA!

It looks like the process for HTC Mail is causing CPU drainage (I think it was com.htc.mail or something - I can't get it to reappear). I Force Stopped this process and amazingly, everything starts running smoother - panes switch like silk, scrolling is smooth, etc. This also appears to be what was draining the battery, as it quickly rose to the highest percentage of what was eating it.
The process gets restarted at some point because I've had to Force Stop it a few times already but at least it stays off for quite some time. So far, it's been about half a day since I had to kill it last.
The funny thing is - I can force stop it and still use all my HTC mail functions properly and they run quicker than ever.
My battery is draining like CRAZY and i cant seem to find out what the issue is. Ive tried calibration several times and using a task manager that turns off running apps every few seconds(which seemed to make it worse) and that didn't help. Auto updates are turned off and fbook is only set to update every hour and brightness is set to minimum yet my battery only seem to last 8hrs. please help. i would really like to pinpoint what the issue is.
Oh...im running ERA Legendary 2.1, CPU speed and voltages are stock
That screenshot is worthless. It doesn't show anything useful. Percentages are meaningless. Get Betterbatterystats to see what is running as far as processes and partial wakes. Get CPUspy. To make sure your phone is going into deep sleep. Get Memory Booster Lite to see what is using your battery and get rid of the auto task killer. That will kill your battery fast.

i only posted the screen shot to show the time vs percentage. i already got rid of the task killer and here is a screenshot from better battery stats. idk how to stop the processes though...
Again the percentages mean nothing. In Gingerbread everything goes through Android system so it will always be highest. If you use your phone only an hour or two a day then it will drop to around 60% with cell standby getting higher. They will always add up to 100% whether on a minute or 10 hours.
You didn't post the partial wake locks screen. Also did you check CPUspy for deep sleep? Did you uninstall the autokiller? You can go into settings>applications>running services and stop applications that shouldn't be running like Facebook or music and video players, etc. Sometimes it's best to get an app like Bloat freezer and freeze apps that keep reloading if you don't use them often.

Another question and maybe the most important...what is your screen on time? I didn't see it in the screen shots. I think Max screen on Time I have gotten is right around 4hours. All the battery tweaks in the world wont help, if your screen is on a lot. Also...make sure to freeze drm, sns and system updates. Use randomlking's zip file.
If none of that works...wash, rinse, repeat. Wipe clean and reflash, rom and kernel.

As I'm sure you know, everyone's battery drainage is widely independent. However; I'm on "stock" Legendary 2.1 and recently with the updated Samurai kernel as well and run Juice Defender Ultimate. I've got some advance settings set but over the past 3-4 days, I average about 20 to 22 hours on a single charge.
My usage in an average day is: about 20-30 texts, about 10 minutes of phone calls, 10-12 emails in and out, 10 minutes of web, whatever app updates there may be and maybe about 15-30 minutes of light to medium use games.
If JDU is something you might want to look into, I would be more than willing to post my setup to get you started. <--For some reason, people are real stingy with their JDU settings.
This kinda thing just happens sometimes, and usually clears up on it's own. Especially common after flashing new software.

Today i have charged my phone to 100% and left it idle for 4 hrs.I opened gsam battery monitor and saw that apps consume 60% of the battery life!! of which dead trigger consumes 50%. how is that even possible? i have not even opened that app and it has been consuming 50% of my battery!!??i have other apps too but those didn't even appear in the list. then why only this app?? That is why i have been getting poor idle battery life. Why does it happen?? Is there any way to stop this without deleting the app??
I'd inform the dev since it's probably the apps fault. If you don't want to uninstall the misbehaving app, you could use Titanium Backup to freeze it when you're not playing. Quite a hassle though.
if you go to the phones main settings, apps, dead trigger.. you can force stop it here.
I'm not sure how long I've been having this issue, but Instagram is draining my battery no matter how little I use it. It seems to stay running in the processes and then eventually stosp itself, even though I see no explainable wakelocks. Sometimes, I have to force stop it myself. Clean Master usually notifies me that it's draining battery, so I know it's not me. Anyone else having problems like this?
Yeah, IG is a battery drainer at times.. Happens with both my S3 & S4, but as long as you swipe it from the recent apps it won't drain battery, that's what I've been doing for quite a while.. Can't believe they haven't fixed this yet
