Incredible 2 and CPU Usage

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.

[Q] Tracking down Wake Lock

Hey guys,
This has been bothering me for a while now, but on occasion, my phone just stops sleeping. I attached a screen shot to show what I mean.
It happened on stock, so I've tried a couple other kernels, but they have the same problem.
Any suggestions?

Yes, probably you're experiencing the "AndroidOS" runaway issue. This is a nebulous and currently unresolvable issue, probably related to some Samsung/Sprint driver issue(s) causing feedback loops between the events/0 and suspend processes. It seems to be fixed temporarily by a reboot, or just randomly. It may or may not be associated with excessive battery usage.

I used to get those solid awakes, but then I froze a lot of apps and it went away.
I didn't do it systematically to figure out which was the cause.
As an aside, if you have an older version of FlightView, then that could definitely cause the issue. That isn't a stock app, but is somewhat popular and had a bug keeping the phone awake *even though it wasn't configured to do anything*.

Ironically, my AndroidOS has always been high (almost always higher than display), but it would always sleep just fine, and my battery-life was pretty good. But every time this happens, my AndroidOS is actually lower than usual.
So I've temporarily disabled Juice Defender (just in case it was interrupting something and confusing it into holding a wake lock) and removed the Facebook widget (Better Battery Stats had that listed as 50% of the wakeup events, which is just ridiculous).
I set a custom reference point so I can watch it for a while and see if anything weird pops up. It seems to be happening more often in the last week or so, and the only thing I did back then was remove Watchdog, because I haven't gotten any alerts for about a month.
I have noticed that usually when it gets stuck in an awake state for a long time, it also coincidentally has a stealth LOS, and rebooting will magically cause texts and voicemails to appear. Let's hope the December radio update fixes that problem.

Android System High Usage

Hi guys,
Anyone have an idea what would cause my battery stats to have very high "Android System" usage all of a sudden. No new apps installed.
Thanks

I'm seeing this get pretty high as well. Starting to wonder... TW really limits the information in the Battery Status dialog. Hopefully we'll get ROMs soon that have more detailed information like I had in MikG.

Did you recently start seeing this? Or has it been from the beginning?

It has always been a bit higher than I am used to. I just grabbed the new version of betterbatterystats from here: http://forum.xda-developers.com/showthread.php?t=1179809
Hopefully I can use this to figure it out.

Please keep me posted if you find anything

System Panel works really well for me I found. Paid version is totally worth it, too.

Just another thought/question...
I am assuming since it is "Android System" causing such high usage ( I have 5% battery left and android system is 30%), that it cant be an app I installed causing the issue.
It has to be something that is either part of the stock ROM (I am stock, not rooted) or something core to the android operating system. PLease let me know if you agree with my logic that it cant be an installed app.
Just trying to find the root cause at this point or determine if I have to hard reset which I dont feel like doing.
Thanks again

The original SGS2 has an issue similar to this.
http://forum.xda-developers.com/showthread.php?t=1290020
They discovered with it that the processor has to ramp back up to 800MHz to do its pre-deep sleep tasks, in addition to taking longer than normal to do those tasks. So with a phone that woke up often to sync, even limiting the processor to 200 MHz with the screen off, it still spends a considerable amount of time at 800 MHz. I don't think they have a fix, but you can work around by limiting the amount of syncing the phone does while sleeping.
Don't know if this is related, since TMO SGS2 doesn't use the Exynos.

Thanks for the reply. My problem is that the battery usage for android system used to be 5% or less and now out of the blue is 25-30%.

Did you change any sync settings? Setting up an email account or maybe a widget to sync could do it. The phone has to do a bunch of system related tasks when it wakes up and goes to sleep, and those fall under "Android OS", so even if it is waking up to sync for an app, the system still has to do stuff, and more than usual when coming out of sleep. Like the other thread said, the original SGSII does all these things at a far higher clock speed than it needs to, and takes longer than most phones do.
I myself don't have the phone yet, nor do I have an original SGS2, but you could look up much of the same information the gentleman who wrote up the OP in that thread I linked to see if the issue is related.

I was so annoyed with this issue that I decided to do a factory reset. I dont think it helped.
So far after being off the charger for 2 hours....I sent 5 texts, browsed web for about 5 minutes. I am down to 87%. Display time is 46%, used for 18 min and android system is 17% with stay awake time at 3 minutes, and there are other items taking up battery at 5% or less like cell standby, android os, market
Does this seem normal, I never rememver android system taking up over 5% even with little usage. I am actually pissed because I would have thought that a factory reset would have helped for sure.
BTW, I am only syncing one acct, Google

I've been watching with betterbatterystats for a couple days now. I've got Skype running in the background so I expect that to use some battery and cause some wake ups.
But it has turned out that location services and updates have been doing a lot more, as much as 7000 in one day. They show up as something related to Maps, but I think that it might be Latitude. So I have disabled that location tracking. We'll see if it helps, there isn't much more using my battery. It is just something keeping it from deep sleeping.
If this doesn't work I'll look at other location apps like weather and such. I already uninstalled Accuweather after reading about how they transfer your location tracking information over the Internet unencrypted!

Battery drain is ridiculous...please help

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.

Is it normal for a phone to slow down after awhile?

I've experienced this issue twice now wherein my phone would get extremely slow and laggy to the point that it's unbearable to use anymore and the only solution was a reboot. Launcher keeps on restarting, messaging app takes 5 seconds to open, camera is lagging etc and this is after a week of uptime at least.
Why does this happen in the first place and am I the only one experiencing this? I've been running only maguro milestone 5 and franco for the past month, no other roms whatsoever. Once I power down and reboot everything becomes nice and fast again.

Never happened to me on stock.
I'd say it's "normal" for a phone to slow down over time as you add apps and things, but it should never slow down to a crawl and start crashing until you reboot.

normal for it to slow down a bit but not like how you described it. i'm running stock though.

It's not normal. Install some monitoring tool like "OS Monitor" and run it when the problem happens to find out the culprit.
Oh and installing multiple apps will not slow down the phone. This is not Windows 95.

lol at the windows 95 comment
although the # of apps you have alone shouldnt slow your phone down, if you have a ton of apps running in the background eating up ram it may slow down if the available free ram you have is really really low
when your phone is laggy check the ram first

Thanks guys I'll try OS monitor to see what's running. It just happened again right now and this is getting annoying, even typing is laggy but after a reboot everything is normal again.

Kill background apps.

So far I have not had that issue. Probably like everyone else said. There is some run away app that's eating up your memory

Its not normal, but aokp does have a bug. Check your system process in system panel, it grows larger over time if you use lock screen options etc.
