So Blackberry Messenger has been available on the Android operating system through the Play Store for just over a week now. Over the weekend I have been paying attention to battery life on my tablet.I have noticed that my battery is not lasting a day I have noticed that BBM is draining the battery and causing some data leakage. The cause seems to be the “always on” feature. Even of you kill the task using a task killer it automatically comes back to life a few minutes later. I am going to remove it until they bring out a new version. This is a pity because it is actually a good app. If you notice the batteries on your Android device seem not to last as long as they should and you have BBM installed its quite possible that BBM maybe the culprit.
