First I would like to say the following:
WELCOME TO THE 3g NETWORK
That being said the I will now go over a few ways to keep your battery going longer, when its really needed. Just keep in mind, as much as we can squeeze from the Bold's battery, it will never last as long as your old BB devices, this is mainly from the over powering 3g network. Although you can never match what how much life the older device have you can still do a few things to help the issue:
First lets adjust some settings:
Options>Screen/Keyboard - Adjust your settings to match these:
Timeout: 20 Sec.
Auto Dim: Off
LED Coverage: Off
Key Tone: Off
Audible Roll: Mute
WiFi: Whenever possible connect to a wifi for your data. This will help your battery life as connection with wifi requuires less battery then the 3g network.
Adjusting these settings will help cut down on energy spent by the battery, making it last much longer. However not long enough. Another thing you can do to help push up the battery life is an OS upgrade. I am currently using the most up to date OS posted in the forum and the OS itself has helped me with battery life. Click on the following link and follow each step word for word and you should have no problem with your upgrade. http://www.blackberryforums.com/gene...ilanguage.html
If this is still not enough for you, I have a few more tricks up my sleave...
Seidio has just released and extended battery for the bold that will add about 15% more life to your phone. EXTENDED BATTERY
You can also try this portable battery thing: FREEDOM INPUT
And of course in case all of the above is still not enough juice to handle your crackberry addiction, you can always use more ways to charger your phone aside from the one wall charger that comes with the phone.
I have taken the liberty and roung up a few links for you guys:
For your lovely car rides: CAR CHARGER
For your office/traveling needs: TRAVEL CHARGER
Don't forget this is for data, but it also charges: DATA CABLE
*Hope this helps!
