Well this is weird. I assumed the same thing must be happening to everyone.

I just checked Pandora, Slacker, Amazon Music Store and PageOnce. I haven't used any of them, and Application Management confirms it. But they've all used small amounts of CPU time today. Other "never used" apps, such as eBAy, haven't. What's going on?

[Howard S.]

I was wrong. I was looking at the "now" time frame instead of "today". I also see small amounts of CPU usage from apps I don't use. I never even setup Slacker and I see it's used some CPU.

Yes, Slacker uses a tiny bit. Pandora uses quite a bit more, even "unused". But how and why do apps use CPU time when they aren't even run?

Tips for reducing fast battery drain:

1. A BlackBerry constantly searching for signal drains the battery quickly. In an office building, residence, or rural area with low signal coverage, you will experience a quicker battery drain. Turn off the xxx8220;radioxxx8221; on the homescreen or the data signal if you must reduce battery drain in severe circumstances (Options > Mobile Network > Data Services = OFF).

2. Check your applications running in the background. Press your Menu key and then choose Switch Applications to see what is running in the background (or, hold down the Menu key about 3 seconds for the App Switcher ribbon to appear). There are commonly four or five applications that will always be running (Messages, Call Logs/Phone, BlackBerry Messenger, Homescreen, and the Browser; there are others such as BeamBerry and Alarms which will also run). Make certain that the browser is NOT on an active webpage (should return the bookmarks page only). Close any other applications that do not need to be running (the camera or a game you were playing or Google Maps). Applications like GoogleMaps and streaming audio apps such as Pandora or the Media Player left running in the background are big battery drainers.

3. Turn off the Bluetooth connection when you donxxx8217;t need it (Options > Bluetooth).

4. Some applications such JiveTalk have a xxx8220;battery save modexxx8221; when idle. Log off applications such as JiveTalk, AIM, Google Talk if you are not using them for long periods of time.

5. Use your sleeper-magnet enabled holster. The magnet in the holster is there for a reason xxx8211; it puts the BlackBerry to sleep, saves the battery, and makes you a happy camper.

6. Turn your backlight down to 80%xxx8230; for many, that is a barely noticeable difference in the screen brightness (Options > Screen/Keyboard).

7. Get an extended-life battery if you think you need it (Seidio Online has many choices for various models).

I am having problems with the battery life of my Bold 9000, before that it used to last the complete day, I don't use it much, but since two days ago, I disconnect it from the charger fully charged and battery only last 3 hours tops, I also noticed the phone feels hot.

The only different thing I did was to activate the bluetooth to transfer something to another device but after that I deactivate it. I also deactived the wi fi to see if it improves, but still the same, I just disconnected it from the charger, not 10 minutes ago and I can see it already drained half of a line from the battery. Please help.

Thanks!

The new OS 7.1 has better performance already.

8-10hrs for any phone is definitely not acceptable and not normal .

Got my new 9900 and use for a week with battery life that last me 10hrs max with low usage . Send in to BB for repair and got me a loan BB 9900 with my own battery and use that for a week and battery life was fantastic that last me 24hrs with still a quarter left .

BB had replace my phone with a new and use back the same battery . And same thing it last me only 8-10hrs with low usage . Definitely there is a manufacture defect or component defect in the BB9900 if not there won't be such a big different in term of battery life comparing the loan phone and my phone .

Will be sending in again and I don't mind they replace me with the phone they loan me which is a perfect BB9900 I am expecting .
