I upgraded to a BB Bold in August. Since then I've had 3 batteries and I'm on my 5th 'certified replacement' phone. The battery constantly drains. I do not run wi fi and don't talk on the phone enough during the day to drain the battery. I don't know what to do but am not getting much help from customer service. What am I doing wrong?? The latest replacement phone came yesterday and I activated it. Already after I drained the battery and charged it all night after 1/2 a day it drained. It keeps getting stuck when I'm trying to switch between apps. Has anyone else had issues or know what I can do to correct it?
In my past experiences with battery drain, I have found most of it occurs when the device is switching back and forth from 1X to 3G for a data signal. This can drain a battery in a few hours. The first thing I would do is to check and make sure you are running the latest device software for your Bold. Currently it is 18.104.22.1685. After checking that, you need to dial *228 and select option 2 to update your PRL. After updating your PRL, pull the battery out for about a minute and then allow the device to restart. See if things work better for you after doing those tasks.
I too had the same problem until I did the SIM card trick and took the mobile network off "global" and I seem to be conserving my battery. I also clear my event log each day - I know a total PITA but it keeps my battery life at a tolerable level. Good luck!
