Big Boss,

Good article for beginners like myself. I am guessing this article was posted in 2008. How about posting a follow up or an update to this original article? New apps have come out and some old apps have been updated.

I would like to see more articles like this one where it is detailed and updated once every couple of years.

I too have had problems with Activator on both a 3G and a 3GS on both iOS 3.1.3 and 4.1…. I have removed it and am annoyed at the number of Cydia apps that require installing it when they don’t *need* it.

This information was very useful. My iphone was recently jailbroken and I have been facing problems with my phone constantly crashing. It ranged from once a day to three times a day. At first I read that it could possibly be the apps that I am downloading from installous were not yet compatible with the iso software on the iphone 4. But I deleted all of those apps, only retaining free apps from the apple store and the phone still crashes. After reading this I realized that the problem could be the “notifier” since my phone and several others phones have been crashing after the jailbreak with the notifier..and my girlfriends iphone has not yet crashed and she doesn’t have notifier installed.

The advice above is excellent, but I had a problem even without heavy daemons or CPU-consuming Safari windows, etc.

Specifically:
I experienced significantly reduced battery life after jailbreaking my iphone 3g (OS version 3.1.3). I was not running anything special most of the time. I connected to the phone and watched “top” for hours to see what might be the culprit. In the end, what worked for me was disabling Activator completely. (Unfortunately this means no backgrounder, among other things.) Using top, I found that installing Activator makes Springboard a little bit fatter in memory size (this happens more after a bit of use) and possibly consumes more CPU (though I’m guessing not so much). I think that given the scarce memory of the 3g and the frequency at which Springboard is active, this made all the difference. After removing Activator, I’ve had my usual excellent battery life for the past couple of days, even though I made heavy use of the phone yesterday (e.g., more than 100mins of talk time).

Of course, your mileage may vary. Many will not even consider jailbreaking to be useful without Activator, but it’s fine for me. Also, it could be that I’m mistaken and I really was making much heavier use of the phone before. So, all I can say is … I’m fairly experienced with system-level computing (though not with the iphone memory subsystem), I tried to resolve the problem for a day or so, and my tentative conclusion (for 3g and 3.1.3) is that disabling Activator (if you can live with it) helps battery life. Try it at your own risk.

Hi again,

BigBoss, did you get my previous post regarding disabling/removing Daemons? What you suggest? Is it safe to remove the above posted daemons? and if you do, do you get more RAM & Speed?

Hi BB,

Many people suggest to remove unnecessary daemons (in order to make the phone faster or getting more RAM) either manually or thru scripts. The suggested SAFE LIST to delete with no particular side effect to the iPhone is:

com.apple.DumpPanic.plist
com.apple.ReportCrash.DirectoryService.plist
com.apple.ReportCrash.Jetsam.plist
com.apple.ReportCrash.plist
com.apple.ReportCrash.SafetyNet.plist
com.apple.ReportCrash.SimulateCrash.plist
com.apple.DumpBasebandCrash.plist
com.apple.CrashHousekeeping.plist
com.apple.aslmanager.plist
com.apple.syslogd.plist
com.apple.powerlog.plist
com.apple.stackshot.server.plist
com.apple.tcpdump.server.plist
com.apple.mobile.profile_janitor.plist
com.apple.chud.chum.plist
com.apple.chud.pilotfish.plist
com.apple.iqagent.plist

What you think? …I apperciate your opinion.

Thanks,
Farnk

I am at my wits end with power drain on my jailbroken 2.5G phone. When I look at “top”, two processes constantly appear, die and reappear with a new PID

398 dataaccess
397 ReportCras

The PID of the above two just numerically keeps on increasing, something is trying to access data and crashes, spawing the “reportcrash” and so on in an infinite loop
Please help
P.G.

I feel like my battery life has declined after installing SBSettings…? Is this normal?

How about an article on what each process is? I mean native ones too.

This way we will know when we uninstall an app whether it’s gone for ever or left a deamon of some kind..
