BBM draining battery even without any use on BlackBerry 10

I've been using Z3 since a couple of months and started facing this particular issue for the past 3 days. The battery was not even lasting half a day and the phone is heating up like hell. I've noticed that BBM is using an abnormal amount of processing power and truly speaking I've never used BBM since I bought the phone. I haven't side loaded any android apps and using the os that came with the phone. BTW my OS version is 10.2.1.2977.

That is odd. If you haven't used BBM it should show it as idle. What OS are you using and what version of BBM do you have installed? It's a little extreme, but you could try loading the OS again. If you do decide to do that backup everything, perform a security wipe, load the OS, then only add back your contacts, pictures, messages, and stuff like that. Don't add the old settings.

My battery was drained in about 3 hours and the culprit was BBM. Similar photos to the ones posted here - with BBM using over 50% of battery, CPU, etc. And I haven't used it today at all. Also the battery/back of my phone was very hot.

Restart your device holding down the up and down volume keys until the screen turns off. I think that works on the Z3.
