Default Re: 9300 Battery Runs Flat

I too was facing a similar issue and finally did find the cause and fix. i found out that the problem is caused by a corrupt or net_rim_bb_phone.api. inorder to find out if this is the issue go to your CPU monitor and see if the Phone keeps clocking the CPU to 100% every few seconds. You can also see the number of hours this has been happening in the day. If this is too much then my solution might help.

For some reason if you try to reload the OS from the same computer again doesnt seem to fix the issue. Also, if you try to load a later version of the same OS from the same OS doesn't work.

1. Remove the installed OS from your computer
2. Remove Desktop manager from your computer. (i suppose desktop manager has some sort of cache that creates the issue)
3. Clean up your registry
4. install desktop manager
5. install the OS 6.0 whatever version that your carrier has authorized. Though carrier authorization should not be an issue if you delete the vendor.xml file
6. Connect your phone and reinstall the OS. you can use backup and upgrade.

Your phone should be working fine and the battery last as it used to be in OS 5.0
