The Device Analyzer which is built onto BlackBerry 7 smartphones is in many ways one of the greatest features that was included in the latest OS update. You will need to be running version 7.1, but most carriers have rolled this out now so I am pretty sure you should all be up to date. If not, then this is a great reason to do so.
The Device Analyzer is one of those features on the BlackBerry that many people won't even know exists. It is not a feature that is promoted by RIM so in order to make the best use of it we have a short 'how to' video. To cut a long story short, Device Analyzer will allow you to monitor applications on your BlackBerry to make sure you are getting the best battery life and power consumption. If you experience WiFi problems the Device Analyzer will tell you. The same applies for if your device drops its connection or you just need to monitor data usage.
These are just an example of some of the features held with Device Analyzer. You can see the short video below and if you have any questions feel free to sound off in the comments.
