Anyone else having problems with the phone locking up?

Or having problems with disconnecting from a Blue Tooth device?

Lastly, the phone battery seems to drain quickly even with an overnight charge to where the light goes from red to green. Now, I bought a new phone battery after the sales associate told me mine has a slight bulge. But after having the phone shut off after depleting the charge, the phone has been holding for quite a long time. However, here recently the phone has been doing it again. I thought lithium ion batteries don't have a memory affect like nickel cadmium or nickel/metal hydride batteries.

Lock-ups haven't been occurring as often as they use to. However, when I go to use the voice recorder, it won't record unless I shut off and reboot the phone.
