Adjust Your Screen Backlight Timeout
The time that your screen backlight stays on may seem irrelevant but if you consider how many times you use your phone in a day, and that each time you put it down it burns for a set amount of seconds, you will realize that you are putting your battery to extra work.
Set your backlight so that it does not squander power and thereby add unnecessary age to your Blackberry battery.
Be Selective when Installing Power-Hogging Applications
Any application requires extra power to run on your cell phone. If you regularly use certain application, you should be aware of how long they run and how much work your battery will have to do to support them.
Google Maps is an example of an application that drains significant battery life when you search for directions, images of a specific location. Application such as Facebook and Viigo are slightly more dangerous as they make use of battery life even when you are not using them if not properly managed. The high volume of back and forth activity consumes large amounts of power that could lead to a broken Blackberry. You should keep strict control of this power usage for a longer lasting Blackberry.
Check Connectivity Options
Wireless connectivity options such as Wi-Fi and Bluetooth eat up BlackBerry battery life even when they're on but aren't in use. Leaving your device's cellular radio on when you're not using it drains battery life, because it's communicating with cellular towers to determine if you're still in range of the network and to update various services or applications. Be sure to exit applications making connections as soon as you are done with them.
Keep your Battery Clean
Dust and grit can creep into place you would never have imagines, so it is wise to clean your battery and the area into which it fits every few months. This must not be done with objects that will damage the delicate battery area and care should be taken throughout this clean up process.
A final measure to ensure that you are never left in the dark without a phone is to invest in a spare battery in case of emergency. Inquire with Blackberry about an extended-life battery as you combat the inconvenience of sending a phone in for repairs.
