What bug? Are you saying the battery was fully depleted after one day?

Could be coincidence? How old is the battery? Is it a genuine blackberry battery or a knockoff? If the battery is a couple years old, of if it is your habit to run it all the way empty before recharging, buy a new battery and see what happens. But buy a genuine blackberry battery from a reputable source.

Have you added any applications that access data since the upgrade? Or started using them diffently? If you have such third-party applications, make sure you exit all of them and do not leave them running in the background, and see what happens.

I certainly do not have any background applications. I have installed "Process Viewer" and can not find any background applications. If the battery is old, then why when I updated my phone firmware 4.2 can be used 4 days. may be third-party. I hope the RIM will have a newer firmware I can update for my 8820

I fully charged battery, I leave the phone from 10 pm to 6 am has consumed 20% of all energy, although in the meantime I do not use the phone.

I'm using 4.5.0.139, for what it's worth. I don't have any knwoledge of the differences between the various 4.5.xxx.xxx with regard to power use. But again, if you are not running app's in the background, the next thought is the battery. How? Why? I don't know. But the battery is the next thing to consider. Maybe it's the problem, maybe not.

In my personal experience, when I see the battery going down very fast, it has been because the battery is failing.
