Re: battery drain prob.

Hello virendersingh,


Welcome to BlackBerry Support Forums


Some time our BlackBerry devices may feel warm say a long browsing session , playing games ,countinous download or while charging Or if applications run in the background . If we press and hold the Menu for a few seconds, it will pop up a screen which will show all running programs in the background ,generally five will always there ( Home, BBM, Message,Phone , Browser ) you can always look if any other apps. are running in the background.


Also always try to Close Applications Correctly - Avoid using the End key to close applications as this simply minimizes the application and leaves it running in the background. Instead, press the Menu key, select the Close or Exit option to exit the application. Don't leave your Browser open when not in use. If programs run in the background it will also lead to overheating and also quick battery drainage. Please have a look at those Article I hopeit will help you a lot in overcoming your problems  :

Hi virendersingh,


On your Homescreen Go to Options > Device > Advanced System Setting > BlackBerry Device analyzer > Run the Battery test to know about the issue .


Or on your Homescreen Go to Options > Device > Application Management . Move your trackpad right or left within it show CPU Usuages , it will atleast give you an idea which application is using your resources .


Check it and see if any app is responsible for the issue .


Regading Charging issue , our BlackBerry Battery are lithium ion battery it won't take too much time to charge , it can attain a full charge ( 100% ) within 2hrs. If your device is taking too much time then be sure you have connected to a wall socket which has a good and constant power supply .Or you have to visit your service provider to check if it's a hardware fault.

Re: battery drain prob.

Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):

  1. With the battery inside, connect your BB to the wall charger
  2. Leave it alone for 2 hours, no matter what the LED or the display does
  3. Remove the battery
  4. Wait 15 minutes
  5. Insert the battery
  6. Wait another 2 hours, no matter what the LED or the display does

This has been known to "kick start" some BBs.

It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:

  1. Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
  2. Obtain access to a known good and identical BB...use your battery in it and see what happens

The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.

Good luck and let us know!
