I'm having some awful slow-down issues with my N1. Like, 3 second delays between clicking widgets and their intended effect, and even longer switching between home screens (if the screens switch at all).
There's no auto task-killer enabled, I've very recently wiped and re-installed CM, and cleaned out my unused apps. I've got around 200MB of RAM free, constantly. SetCPU is keeping my processor at 461MHz or higher. This is obnoxious as balls, and I can't think of much. :s
Any suggestions?
I'm running CM 5.0.6, btw.
i have the same problem
My N1 is not rooted and I am experiencing slowdowns. When opening txt messages now take 3-5 seconds, and typing completely locks sometimes for 20 seconds. Gmail now takes 5+sec to open and other apps are also seeing this. I just had 10+ programs update themselves and all these issues started appearing suddenly. Also when exiting apps my desktop will be blank for 3-5 seconds. This just happened all within the past 2 weeks or so.

Yeah, the issue is very recent for me too. Last week.
I am wondering if Google sent out an OTA that is prepping the phone for the 2.2 update??? The reason I say this and not point to an app is the simple fact that I have all my apps stopped completely and the issues still exist.

Mmm, I dunno about that. I'm running CyanogenMod. I don't get OTA updates. Do you remember, recently, getting an OTA?
Unless it was pushed inside of a market-updated Google app (uhh.. No.), I wouldn't have got it.

You set your CPU at 461Mhz?? Sure it slow down and lagging. What the point buying a 1Ghz processor phone decide let it run at 461Mhz?
Check the profile if you are not set at 461Mhz, maybe accidently make a profile setting and enable.
Or set your setCPU setting from on demand to on performance.
What kernel are you running?

I think he's setting the minimum at 461 hence the "or higher" part.
Well, I can't actually help much except to suggest that perhaps you could try Kang-o-rama (see my sig) and see if that works. It's a stable and fast bundle with no apparent lag. At least I know that setup works.
If you did proceed then posted your results in that thread I might be able to assist. You shouldn't be experiencing lag with this phone... and if you still are after installing Kang-o-rama we could look at logs for you.
No promises but I know Kang-o-rama works...
Success? Sorry for the laggy reply.

Yeah, Copernicus is right, it's at a minimum of 461MHz (now 499MHz.), with a max of 998MHz, running 'on demand'.

Yeah, won't lie, I'm sick of reinstalling all my stuff, so I don't want to do it again. If I keep having issues, I'll look into it though.
Just last night, I wiped both the data partition (factory reset?) and cleared the Dalvik(sp?)-cache. Started from scratch (without Google settings sync.), and reinstalled apps one by one. SO FAR, I haven't had the slowdown, but who knows. All I've got installed yet are the applications that I actually had desktop shortcuts to. (I didn't have very many more, but these are the ones I actually used frequently.)
Anyway, yeah, I'll see how this goes.
K, need a suggestion.

Sooo, it's not going. Still experiencing the slowdown. I honestly can't think of what's doing this. Advanced Task Manager reports > 190MB free (28 processes running), SetCPU is still running at 499MHz or greater (I can't get 'show CPU to work in Dev Tools?).
Ending everything in the "All Apps" tab does not fix the problem; it's speedy for about 30 seconds, then resumes being slow, with the same problems (so maybe it's a process taking up all my CPU cycles? (But my CPU isn't scaling up like it would in that situation...))
Anything I can try doing before re-flashing and/or wiping? I'd rather avoid that, but, of course, if it's the only solution, whatever. Maybe try flashing a new ROM?
Can't think of what else to do here, gentlemen.
Get rid of SetCPU. I had it installed and it started weirding out on me, would not set the processor higher than 384 and nothing I did in the profiles would set it back to 1 GHz. After I uninstalled, my phone returned to it's normal speeds.

You might not like my advice but it's likely to work:
Don't uninstall SetCPU but set your CPU min to 245 and the max to what you want. Disable profiles but select 'Set on Boot' and 'On Demand'. Do nothing else with SetCPU, leave it alone and do not use the active widget. Your current setup is crazy.
Full wipe (as you've done before) data, cache, dalvik-cache, battery, rotate and then install Kang-o-rama 0.7b1 (no, I'm not simply pushing it, I just know it so well that I can assure you it works).
Do not, under any circumstances restore any data or apps for any application with any application. As soon as you set up your Google account go into Settings | Privacy and disable "Back up my settings" and hit Okay.
Install a task manager if you like for monitoring purposes. Install SetCPU as above if you like for OC.
Install no other apps (now that's the painful part) and use your phone for long enough for you to know with certainty whether it's working as you expect.
In all honesty, if it's still broke after that then you've probably got a hardware issue. If it's working after that then slowly add your apps back until you find what's causing the problem.
Good luck, report back.
So far, uninstalling SetCPU is doing wonders for me. Y'know, over the last 15 minutes. I'll use it throughout the day and see if it keeps performing.
Space for future updates:
****ING BALLSACK. <--- First impression of Kang-o-Rama (I decided to just go for it and flash as soon as I saw it included CM.)
^^^^^^^^^^^^ That text is to be read: Kang-o-Rama is amazing. The theme is sexy, I LOVE the Desire camera, and the bundled stuff (kernel, apps, etc) are quite awesome. We'll see if it solves my performance issues.
I was getting the same thing....
Task kill setcpu and reboot it again. If you keep getting the lag then stop using setCPU.

But thank you!
Delete all widgets that profile your cpu in any way. Stop killing tasks with task killers. Uninstall setcpu. Set exchange email app to "PUSH". Download "Quick System Info Pro" and check what's using up Cpu.
I had the same problem and it turned out to be 2 things: SetCPU widget and exchange email app stuck in a sync cycle.
Maybe theres an ill-performing app that you installed. Since it seems you wiped your phone a couple times including cache. Did you happen to restore apps thru Titanium backup or manually one at a time thru the market.
I always wipe my phone completely and reinstall all apps manually, time consuming, but I have never had a problem.
To further diagnose your problem, see if after installing each app, try the phone to see if there are any slowdowns afterward. Again, I know this is time consuming, but trying to find the problem rather than living with it would be better.
I'm also using 5.0.6 but with no problems or slowdowns.
You can also post a logcat or look thru it yourself if you know how and see if any errors or hangups occur. Logcats are a great way to see the commands being given to your phone and this will most likely reveal your problem.
Same problem, it's annoying.
Has anybody figured out a way to use the back button to exit out of programs instead of hiding them so that you don't have to go to "manage applications" in order to force close them and save battery life?...i know, run.on.

From what I understand the MT4G is supposed to do a job on it's own of closing most applications most of the time, better then any other android had (at time of release anyway). I suppose if you think it's that big of an issue you could download a task killer, but I've heard over and over again to not use on on the mt4g because you just don't need it. That's just what I heard though.
Could be wrong, wouldn't be the first time.
Is there a setting for that then? because nothing closes on my phone
yeah i agree on NOT using those task killers. i have seen many posts from devs saying they cause more problems then there worth. interfere with apps causing force closes and some other thing that i cant remember off the top of my head.
Google up "Why you shouldn't be using task killers with Android", read, educate yourself, and stop doing unnecessary things with your phone. Understand how things work before you attempt "making them work better", and screw them up in the process.
Ok sounds good, but why then when you get rid of the bloatware like "amazon mp3" by disabilig them, do you get improved battery life? What am I missing?
You don't. Battery life won't be bothered by having or not having Amazon MP3. The only thing you get is more memory (which isn't used anyway) and more space on the /system (which isn't used anyway). Additional thing you get that IS used - is less cluttered app drawer.

Task Killers do more harm then they do good. any developer, any coder, any one with any Android knowledge will tell you "you do not need it, and they do more harm then good". In fact Google themselves has said that it's not worth it. and the dev team @ Cyanogen will not accept a event log for trouble shooting if you have used a task killer.
But the reason we delete bloat ware is to gain that memory for other applications and data. no all apps can be stored to the SD card and they do leave a foot print on the phone. So we delete them to gain the space back.
Android phones are Lunix based computers which can multitask lightyears better than any current windows based computer system, phone or server. They were designed with this very principle in mind. In fact if you have ever used Ubuntu 10.10 they have a 4 "work spaces" where you can do different stuff simultaneously. similar to the "home screens" on android.
as far as them "running" in the background they are not absorbing any data/battery/resources from your phone. They are setting in a "frozen" state until you open them. In fact, if you didn't know this, if you press and hold the home button you can access recently open apps. It keeps them in the "frozen" state so if you switch back to them they'll open where you left them.
Thanks for all the comments. But I don't need convincing on the task killers; I understand they're worthless. My intent was to find out how to make my phone perform better (battery life-wise). And although I think I have a better understanding on how android handles apps it also just confused me.
I used to get 8-10 hrs max on my phone and basically have to charge it all the time. Since I temp rooted (permroot isn't working for me) using VISIONary and disabled a bunch of apps using Terminal Emulator, I'm sitting on 23.5 hrs off the charger right now with 45% battery left!!! And all I did was disable apps. So I'm mad confused how I'm getting so much battery life when the only thing that's changed in my phone according to you wouldn't change anything.

battery life has alot to do with your social networks, and syncing. If i turn off everything, and turn the screen brightness to about 25%, i drop about 2% per 5 hours. So it really depends on what you disabled, and if they were absorbing any resources on your phone.

That is correct. However, there is one situation in which I do end apps, and that is in the case of resource-intensive, 3D games. The MT4G has so much RAM, that even games like NFS Shift, X-Plane, and Jet Car Stunts never close. They stay running in the background forever, which is unnecessary. So I'll close those, but no other apps.

Hi, I am using watchDog to try to see what processes start while the phone is in sleep mode. But I cannot find anything on WatchDog that tells me what is consumming battery.
I hope I make it clear.
The situation is the following.
When the phone is sleeping, with no 3g or wifi, it takes around 10% in 8 hours. Just iddle. This happens at night. When sleeping.
As soon as I wake up, I turn on 3g. And the battery starts draining. I understand this is normal. But should the phone be awake all the time just by having 3g on?
The awake bar is almost full. Eventhough the phone is locked. This happens only when I turn 3g or wifi on.
That's basically my question. Sorry if it is misleading or something.
Regards
the phone will be awake if you installed some rogue app that connects to the net every 2 minutes to check something, or just some badly coded app.
So I should start uninstalling each app to see which is the one? Or can I use an application that will tell me that? Itried watchdog, but got no success.
Any ideas?
I've found eBuddy to keep my Awake bar completely solid... EVEN if I'm completely exited out of it. It has to do with the fact that like any other app, Gingerbread keeps a cached version of the process in the background. But in eBuddy's case, staying cached causes the phone to stay awake, so the only way to resolve this is to completely kill eBuddy and any of its cached processes.
That's why I still run ATK at 30 minute kill intervals. Getting great battery life. Here's my original post on this issue:

You can start by going into settings -> applications -> running services
Tap the "menu" button and make sure you are looking at only "show services in use" as opposed to all services including cashed.
You will get a list of about 10-30 (depending on what you installed and how you configured the phone)
Then go to settings -> accounts and sync, and under "manage accounts", see what accounts you created that sync up with somehting. make sure the icons (round circles) are green only for the accounts you truly want to sync.
Also tap through each account you do want to sync and check the sync settings . If there is an account that is set to sync every 2 minutes, or is set to sync at an unreasonable short time, change that. There could also be a bunch of account you what to totally switch into "manual sync" mode, for example email addresses you do not care about.

I do Crazy, 30 minutes, and Low level so that I can see all processes (including system level). I then run my phone as usual and add any/all system related processes to the ignore list.

I just made a test, and found that the app that makes my phone to be awake all the time is the MSN Talk Pro.
I disabled it, and everything went to normal.
Is this normal in IM apps, since the other person was having the issue with ebuddy?
How could I have the IM app running without having my phone awake all the time?
The task killer would definetly work, but then I would not be able to get msn messages.
Is this the only option?
Thank you.

Let me try to explain the situation.
If you have an IM client and you want it to be ready to accept messages from your buddies, it has to be in "listening" state to "hear" from your buddies. How that "listening" state is implemented by the developer defines how much batt power the application is eating.
Two opposite example:
1) Some stupid developer coded the IM client to always stay in foreground on your phone, actively pinging the servers on the internet , asking the servers if you have new messages. Your battery is wasted big time man.
2) A smart developer coded the IM client to use Google's C2DM interface (Cloud to Device Messaging framework). Such an app will stay dormant on the phone, and will be woken up by the android core processes whenever a new message arrives for you - Google servers will wake up the app on your phone. Such an app will not waste battery much.
There are a number of variations that go in between (1) and (2) above. So there is no clear-cut good or bad app. All depends on the implementation, and also on the way you configure your phone and the app on it.
Latest version of eBuddy was supposed to use C2DM too.
Ad the new Trillian is using C2DM. I never tried any of these though, can't vouch for any.
Just keep trying various IM apps until you find one that does not stay awake.

It has worked for me mate, worked well I should say. You deserve a Thanks mate.
I set it on Aggressive mode, with Auto kill at an interval of 1 hour, and NO apps but only my Power Schedule app in Ignore list, and I kept the Network On (Normally I use Flight Mode at night time), and after 9½ hours the battery drained just 2%, from 90% to 88%. Usually on Flight Mode I used to have a 3-4% drain overnight, so it's a big improvement.
BUT there are still two small but solid Awake bar present there while the Screen was off! What could be the reason? Is it because ATK was running and caused the Awake bar by itself or other apps? Take a look at the pic.
I have another query,
If I don't add any system apps (those come by default) to the Ignore list will there be any problem?
Regards.

I have recently removed watchdog and noticed that battery consumption rapidly reduced...
Yes, I read the other threads out there but no true answer.
I have a ton of apps in my auto-end list... I've heard two things, keep em on there and let them kill them but I also heard for Android 2.2 and above it actually hurts the battery life because it takes more juice to restart the app after being killed then actually leave it running. Any insight on this at all? I currently have every app that isn't a widget on the auto-end list and would like to know if I should stick to this or get them off there?
I added and removed stuff on the auto end list and it doesn't seem to make a difference to me. I started to "freeze" apps from starting by using Titanium Backup. I know it costs a couple bucks but whenever I change ROMS, it reinstalls all my apps that I had downloaded. There's apps like weather service and news, DLNA, and a few others that I don't use but when I look at running apps they are running. Hope this helps.

I use Gemini App Manager to alter the auto-start conditions for every app. Apps don't start until I start them. Isn't a noticeable difference between startup times for me. Once they are running, I let them run or quit on exit if the option is there.

I have TiBu and do freeze apps I don't use but I'm talking like the Market staying open after you shut off the screen or the messaging app, etc. Not apps I don't use, I'm actually talking about apps I use, apps I don't use are already frozen.
I wouldn't have anything on auto-end list... It basically force closes the app every time you exit out of it then, which is a big no-no.
The way I see it, if an app is using battery in the background, it needs to do it and shouldn't be closed. If it doesn't need to use any battery or processing power, then it won't even if the task manager SAYS it's still running (it's really minimal).
Task killers are probably only useful to kill apps that are going haywire and running when they shouldn't be...In which case, reinstall or just don't use that app.
But I say, don't put anything on auto end. If you are worried about losing battery, lemme tell you I get two days of battery life and I don't do even have a task manager. I just use setcpu to underclock while the screen is off/while I'm sleeping/etc.
I wondered about this too, and while some people still claim to get better battery life with one, I always see articles like this: http://androinica.com/2010/05/googl...-imply-task-killermanager-apps-are-pointless/ that tell me you should never use one ever.
You don’t need to kill an app just because a task manager says it’s running. Android automatically closes apps if the phone requires RAM or if that app remains inactive too long.

There's also this quote that seems to argue that it's more harmful:
Applications may seem present to the user without an actual process currently running the app; multiple applications may share processes, or one application may make use of multiple processes depending on its needs; the process(es) of an application may be kept around by Android even when that application is not actively doing something.

I keep something around to easily pick out running apps to force close if they're borking out on me, but I don't have any auto-kill or kill all running apps with a whitelist or anything.

I highly recommend doing the battery optimization first before customizing the settings.
First thing you want to do is change the default notification from Silent to something else so you hear when you have emails, texts, etc.
There is a lot of stuff in the optimization guide to help you get things started and set-up. I like going into the Messaging app and have it not only divide texts into 160 character blocks but also number them so people know the reading order as they aren't always sent and received contiguously.
I think that is a good start for now!
Being a CM9 user since day 1 I figured out that you will NEVER want to use an app form the market which allows you to change the frequencies of your phone. I found out that it drains battery EVEN MORE then when using the built in one under Performance.
And I highly recommend that you get Juice Defender. Ultimate is best because it allows you to choose what apps you want to have data turned on for.
And if you monkey around with Voodoo control I'm sure you'll find something to your likes.
Screen Filter from the market is also a great tool. If you think the lowest brightness is to much and want it darker then use that tool.
I recently learned that custom kernels are not recommended.

I'd like to know how this is possible. I mean, if you're undervolting (throwing less power to run a specific speed) I would like to know how this actually drains battery quicker. It simply goes against logic.
Not saying I don't believe you, but I would like it explained why this is true.
CWM flashable Sprint Visual Voicemail
http://epiccm.blogspot.com/2012/03/customization-guide.html
Sprint Visual Voicemail now works on CM9, meaning we now have three options for visual voicemail on Epic! Read the Customization Guide for CWM5 flashable .zip and setup instructions if you want to use it. Be aware that there are currently glitches.

I can't get it to work at all. It installs and looks like its all there but I've left 4 voice messages for myself in the past hour and nothing.

Did you run the app once? It provisions the first time you run it, and tells you with Toast messages.

Yes it did all of that as with any tw rom when you do fresh flash and set up phone. I even just for nostalgic reasons played the two set up messages. But I then used my wife's phone and called myself and left several voice messages but nothing comes through the app. I read everywhere people having success with this and I'm struggling. I even tried sending the [email protected] message and it looks like it sent but nothing happens.
Edit: I am getting the text messages alerting me that o have a VM but the app is not downloading the messages. I still have to dial #1 on dialer to dial my voice mail.

I get a 9016 message with provisioning successful but if there was a toast message it was so quick I missed it but I don't think there was one. Does this mean that I need to delete data for the app and try again or does this mean it provisioned but like edfunkycold I too get the text messages about new VM but the app doesn't download them. In fact the messages aren't on sprints VM system like the app told it to delete the message as if it had downloaded, even though there is no message in the app to listen to.

Well its mainly for those who leave it in their pocket for long periods of time. Because if you have apps like twitter, facebook, or anything like that they run in the background and the cpu will require more power to run them all. Now if you used an app from the market to control them it would drain battery because it requires battery to run apps in the background and that app you supposedly have from the market will run in the background, thus causing battery to drain even if you're under volting it.
If that wasn't very clear tell me.

Same problem here, except I dont think that mine are getting deleted, cuz I can still call my VM and listen to them. But for the life of me I can not get the VVM to work, I have tried absolutely everything I can think of. Please if anyone can figure out what the deal here is, it would be greatly appreciated. The loss of VVM was pretty much the only thing I didn't like about This CM9 for Epic, since I flashed the alpha 1.
Edit: Just an update: when I use Sprint VVM to compose a message to myself, to test send and receive functions, It sends the VM to me just fine. I get the 9016 text and its on my VM but It still does not show up in the Sprint VVM app.

Exactly how I tried to test it except the message I composed and successfully sent was not on VM when I call in after getting the 9016 message saying I got that VM. This is what leads me to believe that sprint VVM is failing to download the message and deletes it from the VM system as if it had.

I see where you're coming from, I think. So you're saying Voltage Control, for example, would be running more frequently if I have a lot of apps that update in the background becuase in addition to those apps running, VC would then have to run more to produce more power to run the other apps.
I guess I was under the impression that VC would run at boot (however you have it set up) but it wouldn't continue to run once the settings were in place. For example, I never see Voltage Control as an app listed in the running apps or or cached processes for that matter either.
So then my question becomes if it's not an active running app, and it's not a cached app either, how is it draining more battery?

i dont think it does. i never see it as a running app, and it doesnt show up as using the battery in battery stats, so i think this guy is misinformed on that aspect. if youre using undervolted settings with the ondemand governor, you probably wont be using more battery than on stock. im in know way absolutely sure of this and im not a dev or computer genius or anything like that, but im pretty sure the battery problems that DO occur are on the custom kernel side. since a custom kernel is needed to overclock and undervolt, and some of the 3rd party kernels have had some battery draining issues, like wake lock issues and stuff, i can see where one would get the impression that using an oc/uv app might be causing battery draining issues. i myself am using the shadow kernel which oc's to 1400 mhz and at first was getting terrible battery status. but after messing around with a few settings, reading up on tips for saving battery, and tweaking juice defender ultimate to my liking, im getting exceptional battery life. almost as good as the stock kernel. i would have dealt with a bigger difference in battery drain for voodoo color anyways. not to mention, the added bonuses of being able to oc/uv. im in no way trying to knock the stock kernel, my preference is just that, my preference.
as far as a custom kernel not being recommended...thats easy, its also not recommended to root your phone or flash a custom ROM. nuff said, right?
p.s. while voltage control does NOT show up on my battery stats, juice defender ultimate DOES. VC does NOT seem to be running in the background at all times, but JD definitely IS.

So after a big long ordeal (accidentally flashed mtd over bml and soft bricked my phone for a day lol ) I finally got it fixed with odin. Then I managed to get back to a working backup that had a working version of Sprint VVM and backed up the data with titanium backup then got my cm9 beta 0 restored and flashed a fresh version of SVVM then went in and made sure it was set in the dialer settings and then restored the app data and the provisioned and still no damn luck.

This is because VC loads the custom changes at boot time and is no longer needed. Where as JD is a service that performs periodic actions based on how the user setup JD. In essence JD will consume a slight bit of battery but the increase in savings will outweigh it's consumption. If anyone would like I can try and determine JDs exact usage if it registers in any of the available tools for checking apps battery/CPU usage. As far as I'm aware it does not show up in androids battery info section commonly used to show battery usage in screen shots here on the forum. I of course would post those findings if any in the battery thread.
For those who can't enable the native HOTSPOT as reported on issue 148, try side-loading android-wifi-tether.
With AWT, I can have AP infrastructure hotspot using netd, with WPA2 encryption and multiple Android devices connected. The trick is to configure the device profile as an Epic 4G Touch, Galaxy or any Samsung device that shows netd option in the Setup-Method. Optionally, turn off driver force-reload to get rid of a harmless error message (works fine either way).
A nice thing about AWT is it shows the hotspot real time, accumulative bandwidth usage, and if you don't need to use AP infrastructure mode, you can even lower the ad-hoc mode transmit power for lower battery use.
It also has MAC-based client access control, and on TW ROM, it would give hidden SSID option.
(sorry for posting this multiple times; just thought I'd share my finding on all the relevant threads.
ok what sound manager app is better....
i have bought voodoo
I know that DSP comes with cm9...
I use Voodoo (paid version) so I can limit the headset volume on my kids' Epics.
FYI: For those of you that are having issues with VVM, are you using GoSMS? If so, it's been posted in the CM9 tips and tricks thread that GoSMS and Sprint VVM dont play nicely with one another.
Freeze or Uninstall GoSMS and your VM's should start trickling in!!!
