After having used eight BlackBerry devices – Curve 8520, Curve 8300, Curve 8360, Curve 9860, Bold 9650, Torch 9800, Bold Touch 9900 and Torch 9810 – it is my conclusion that joining a BBM Group on your device will impact the performance of the device severely. Your BlackBerry will become sluggish in a nightmarish way.
Every single time I have joined a BBM Group on all the above-mentioned BlackBerry devices, the devices began to exhibit serious lags and freezing. BlackBerry OS 7 hasn’t changed anything. The pattern is the same.
A friend is subscribed to three BBM groups, and she finds using her BlackBerry hellish. Three groups! Unfortunately for her, she says all three are important and work-related, so she is unable to remove herself from them. Personally, when the lags and freezing became unbearable for me, I removed myself from the famous Mobility BBM Group (I’m guessing that I’m being missed now. Sorry guys, but I cant bear inefficiency of any sort).
Since exiting all BBM group activity, my BlackBerry has worked smooth and I haven’t experienced any of the serious lags that I used to. Finally, I am a happy BlackBerry user.
If you are experiencing severe lags and freezing on your BlackBerry, chances are that you belong to a BBM Group. Get out of the group/s and you will experience better performance on your device.
