just recently purchased a blackberry curve maybe 1 1/2 to 2 months ago.
didn't start having issues with it until i downloaded applications. didn't end up caring for applications and removing them because they were killing my battery and lagging my phone.
i am only ever connected to the verizon network, and whenever i am finished with a website, i close out of the browser.
my question is, why is my battery still draining?
up in the right hand corner, i see little arrows going in each direction.. as if to imply my phone is receiving a message and sending one out. however i have not done so.
i've even tried pulling the battery a few times to see if maybe that would help but, no luck.
i charge my phone while i sleep, and half way through the night realize it's done charging and remove the charger cord. i wake up in the morning to find it completely dead again.
You probably installed some kind of app that uses data a lot. Littona is right, you should see those arrows when data is being trannsferred. Check all your running apps, and close them all. Also, I'd recommend updating to the latest OS, which is 5.0.0.734.
