I am on the BELL service in Canada. I can only tell you based on my location and with the policies from the carrier that I am using. I have to log in with a name and password.
You should be able to go to the Application World Page with your computer and create an account. Once done, you should be okay to log in with the phone or your computer and manipulate, or download the Blackberry programs concerning your phone.
I use this link for Application World: http://appworld.blackberry.com/webstore/ On the upper right is the prompt to register. It is located next to the login command. After registering, you should be able to log in from the phone.
If this does not work for you, I would suggest for you to call the tech support for your carrier, or directly to the Blackberry support people.
As for the rate of battery discharge during use, the more applications that are active, the greater the rate of battery usage. If the phone is accessing a lot of data very often such as having many email accounts being monitored, or if you are doing a lot of web browsing, this uses more power. I found streaming videos and heavy use of the GPS application uses the batteries at a much faster rate. Talking on the phone is also a heavy power usage.
When the phone is in a weaker reception area the rate of power consumption is also higher because the transmitter section of the phone has to put out a higher power of signal.
Some tips for power savings in the phone:
- Set the screen brightness to a lower level. The dimmer the better for lower battery usage. I use about 60%.
- Turn off the Bluetooth and WiFi feature when it is not required.
- Avoid having applications opened in the background if applicable.
- Use less email accounts. You can set the phone up with a few, and have your email service use forwarding to one or two email accounts.
- Make phone conversations as short as possible when applicable.
Battery drain is a common problem with these types of phones. Some types are worse than others. They use very advanced and sophistacated systems, and require a fair amount of power.
I carry a spare phone charger with me, and also an extra USB cable. When I am in my office, I recharge the phone from my PC. I also have a charger in my car. Because I am a very heavy user, I keep topping up the charge through the coarse of the day.
Just for you to know... I am a user of some Blackberry products, and I have a technical background. I do not work for Blackberry or the telephone carrier. I am giving some advice as a contribution to this forum.
