After you’ve set up all your various accounts, you’ll notice that the same person, if they appear in multiple accounts, will be automatically merged together. If a contact with multiple entries doesn’t merge, you can manually link them together using the following tip:
Open the Contacts app
Tap and hold a contact you’d like to link together, e.g. Ty
Tap Select More
Tap the other contact you’d like to link, e.g. Ty Williams

This one not many people think of but it can also be a big help on the battery. If you happen to find yourself in an area with poor network coverage for your carrier, you can change up your settings or even turn off data completely and save yourself some precious battery bars. Sometimes when you find yourself in poor coverage it could be due to a clogged network (as happens often to the Crack Team at tradeshows or for those who are on AT&T in big cities like New York or San Francisco).
If this is the case, you can access your Network Settings and change your device from 3G/H+ down to 2G. This drops your "3G data" and gets you on the slower 2G network, but also clears things up as your device won't constantly struggle to find a data connection. It may sound a bit odd, but in times of need it definitely does the trick. Depending on your situation, this could literally add a day, never mind hours, to your battery life.
Change your Network Settings to 2G:
Click on the Network Settings area on your home screen
Choose Networks and Connections > Mobile Network
Choose the dropdown box next to Network Mode and select 2G
Alternatively, you can totally disable data on your device by simply turning data services off in this same menu. Keep in mind this will kill all data to your device, so apps, emails, BBM and the like won't be received.
Bluetooth is a great feature of BlackBerry smartphones. It lets you connect with devices such as headsets, computers, speakers and much more. However when not in use, having Bluetooth active can slowly take away from your overall battery life. When you're not using Bluetooth it's always a good idea to just turn it off. Granted you won't be able to automatically connect to devices without turning it on again, but it's only a few clicks away so it's never too much of a hassle to fire it up again.
To Disable Bluetooth:
Click on the Network Settings area on your home screen
Uncheck Bluetooth (to enable Bluetooth repeat the steps but check the box)
As for Bluetooth while talking on the phone, the Crack team debates this one back and forth. Arguably you should get better BlackBerry life if you're on a call using a Bluetooth headset or Bluetooth Speakerphone (since you're now saving your BlackBerry from having to use it's microphone and speakers). Over the years we've found this can vary a bit depending, so it's something you'll want to test out with whatever Bluetooth Accessories you use. But for sure when you're not using Bluetooth, turn it off.
