Bold 9900 - Sudden battery drain

I have bold 9900 which is 4 months old... For past 7 days, its battery suddenly drains even if it is lying idle.... From 100% to 80%, it works fine... then suddenly falls to 2%

 

I have done the following so far:

- Clean wipe and reloading OS;

- Checked no app is running in the background

 

I have not installed any app for the past 2 months... No change in phone ... I am using the phone in the same way.

 

Pls help.....

 

Regards

Re: Bold 9900 - Sudden battery drain

Hi and Welcome to the Community!

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!
