Default Blackberry Battery Randomly drains?

Please Login to Remove!

Hi - I have an almost 3-month-old 8330. Last week, i put it on my desk at 9:30 AM after listening to Internet Radio on BerryTunes for about 10min. Battery was about 75%, and I know I stopped the stream. 2 hours later, I picked it up and battery was dead.

Last night, I turned it off with 80% battery and this morning I went to turn it on and battery was dead.

I don't know what to do - wipe and re-load it? Get it replaced? Replace the battery?
At all other times last week, Battery drain seemed appropriate (about 10% per day).

Any thoughts from you more experienced folk?

It sounds to me like you're leaving applications running in the background. You may stop the streaming, but do you completely close and exit out of the application?

If you press Alt + Escape, what applications currently show running?

I would follow these steps:

I will start using the Alt-Escape and read that FAQ. THanks. However, I turned the silly thing OFF last night -doesn't that kill all the apps?

What button is escape?

wiping and reloading the OS will do nothing for a) leaving apps running active in the background b) a device that could be badly calibrated to the actual battery charge or other matters.

Read this and see if any of it applies to you:

By holding the power button? No, I don't believe that does. You will need to physically remove the battery to end all applications simultaneously, that or press Alt + Caps + Del.

I just confirmed this. I opened up Opera Mini and then shut the device of by holding the power button. I turned it back on and Opera Mini was still running.

ok - I didn't know powering off didn't really kill it. The event log shows activity at 4:39AM. I wonder what is running?

Thanks for all the diagnostic tools, I didn't know about them
But Please - Which button is "escape"

It is the button to the right of the trackball. It's commonly referred to as the "back" key.

Ok - So there is a hypothesis that covers all my data, but I'm not sure it makes sense.

Last week, BerryTunes was -active- even though it was not playing.
Last night, Media Player was -active- even though it was not playing.

Can these apps draw battery even when they're not playing out anything? and even when the BB is turned off?

thanks!

(ps - i read the battery faq - not a lot there, I usually let my battery run down to about 50% and then charge it (once a week), and i cut the backlight to 70% already. Thanks though)

I am not familiar with BerryTunes. It's possible that it is. Even if you're using your browser and on a page that refreshes randomly, like a weather page. That will cause battery drain. Facebook is known to do so as well. Some 3rd party apps are notorious for that. It's always best practice to press the menu key and select close/exit when not using the application.

yup - I'm getting that - and it's something I plan to do. Although, I'm surprised that turning the unit off doesn't have the affect of 'kill all apps'. I mean, the only possible think I expect the BB to do when it's off is watch the clock for when it's next supposed to auto-turn on. Do people really run apps that they expect the BB to run when it's "off"?
/more of a newbie than I thought.


Thanks - both the speed and quality of responses to this inquiry have been AWESOME. I Learned A LOT (I also tend to keep my browser open and will stop doing that too!)

I think you might could read it again. There's nothing in there recommending a full charge once a week.
