I've had a BB 7250 for about 2 days now and I noticed, already, that it burns battery fast and takes a while to charge. Is this generally the case? The wall charger it came with seems like it takes a really long time to charge up the battery. Is this by design? Will a car charger take this long?

The wall charger should recharge the battery fairly quickly (few hours). You may have a faulty battery.

It also depends on how busy you are on ur BB...
Try adjusting ur backlight, stand by settings and all that other settings related to power...also try letting the battery drain completely and charge it for 8 hours...if it still drains fast and ur not a busy BB..I suggest getting a replacement or an upgrade to the bigger battery...

Well, I had it plugged into the wall for two hours with no increase in charge. I plugged it into the USB port on my computer and it charged up in about an hour. The wall charger says it is charging, and eventually does, but man it's slow.

i would recommend exchanging the charger

It's an issue that I've seen many times...we always recommend using the wall charger...for some reason the USB cable doesn't always charge properly. if the travel (wall) charger isn't working, I would ask for a replacement of THAT charger.

Also, make sure you turn OFF your BlueTooth settings when not in use. When I turn off my BlueTooth, I get almost 2x the battery life out of my 7105T.

Just my .02 cents.
