Default Apps opening at rapid speeds, destroying my battery.

running with the moto droid - since the latest update, my phone is chronically opening apps every few seconds and it is destroying my battery. before the update, i would have to kill maybe 3-4 apps over an extended period of time. now it takes about 1 minute and i'm killing 10-15 apps. any reason for this happening? how can i fix it? it's getting annoying when my battery life is terrible. i don't know a whole lot about the phone.

thank you in advance!

The reason is because you actually auto kill apps.
Apps don't waste any battery doing nothing in the background. It's perfectly fine for it to do that. Android was designed like that in mind.

If you go around killing everything, they will just start up again. And THAT is reducing your battery life.

It's because you all have a rogue app on your phone. You have a poorly programmed app that's not letting your phone sleep. In 2.1 you could use a Task Killer to kill the poorly programmed app thus applying a bandaid to a bleeding wound. With Froyo, task killers don't work. Google has crippled them because they were causing stability problems with the OS. Now you have a bleeding wound and no bandaids. You need to hunt down the rogue app.

Get a tool like System Panel. The lite version worked beautifully for me and after running the phone for 4-5 hours I was able to figure out that the AppBrain app was not letting my phone sleep. I uninstalled it and the problem was solved.

Thanks for the reply. What you say makes perfect sense. Yesterday I had my phone in my pocket for about 2 hours and when I pulled it out, it was really hot, and the battery was almost dead.

I'm very new to smartphones (only had this droid for about a month). On the advice of the Verizon salesman, I loaded ATK (uninstalled now). I haven't installed very many apps at all (Pandora, NPR, etc).

What is System Tools? Is it an app that tells you which apps are running your battery down?

Also since the update, it seems to freeze a lot now, and I can't sync with my work email due to some unspecified "security problem" that won't let me connect with the server.

Again, everything worked great before the update.

Thanks again

How were you able to pinpoint AppBrain as the problem? I used System Panel with 2.1 to kill individual apps (since ATK made you kill everything). I never fully understood the other features of System Panel, outside of ending a task. I'd like to know how I can pinpoint an exact app causing battery drain, since I've noticed a reduction in battery life since upgrading my Incredible to 2.2, and that's with an extended battery.

You kind of have to go into some of the details on it. I'm at work right now so I can't fire it up to check. I'll post on it once I get home.

Thanks A. Nonymous! I can tell that just uninstalling ATK has resulted in a 100% improvement in battery use already (phone is not hot just sitting there and battery still about 80% after several hours).

I'm going to un-recommend SystemPanel though it does work. I heard Leo LaPort recommend an app called Watchdog that I think works better. I'm using the Lite version that's free in the Market.

Long story short, if you're getting crappy battery life your most likely culprit is a rogue app. A rogue app in this case is not an app that's out stealing your data or anything like that, it's merely an app that won't let your phone sleep. If you go to Settings >> About Phone >> Battery, you'll see at the bottom a meter that says Up Time and one that says Awake time. Up Time is the time your phone has been turned on. Awake time is the time your phone has been awake.

Unless you are constantly playing with your phone, making calls, sending texts, etc... and constantly touching the screen, these numbers should be different and usually pretty dramatically different. For example, your up time may be 12 hours, but your awake time may be 4 hours. That means that your phone has been turned on for 12 hours. During that 12 hours, you've spent 4 hours talking on the phone, texting, using apps, etc... and the other 8 hours you haven't been touching the phone so it's been in your pocket or wherever sleeping. Awake time should be less than Up time.

Rogue apps keep your phone from sleeping though so it is always awake and always running. This sucks battery life like a leech. Download Watchdog. Start it up and let it run for a couple of hours. Don't use any task killers. After a couple of hours, go into the Settings >> About Phone >> Battery page and look at the sleep time vs awake time. If the times are very, very close and you know you weren't actively doing anything with your phone for that amount of time, then you've got a rogue app. Go into Watchdog and go to the CPU panel. You'll see a list of apps. You'll see the name of the app and then a per cent next to it. It's usually pretty small unless you're actively using that app. If you see an app that's much higher than the rest, then uninstall that app, reboot the phone and see if the problem goes away. If it does, you've found your rogue app.

I'm the same, Looks like some phone build of Android have different things.
I have an Uptime, but no wake time.
The rest of the info is still relevant though.
