For some reason I can't post my long post here - I'll try again later EDIT: For Easter, my family went to my Aunt's house all day. They live in a HORRIBLE cell phone reception area and basically no one can get a signal there. After being there several hours, my mom shows me her phone and the battery is completely dead. She kept insisting that she just charged the phone and that she had a full battery when she left the house. Being skeptical of her claim, I pulled out my cell phone and put my battery into her cell phone. Her cell phone worked, so I concluded that the battery was dead. She was all like "But it was completely charged!!!" I didn't know what to say and figured that maybe her battery was no good and she needed to bring it back to the store. BUT! When I looked at my phone, my battery was half dead. I charge my phone every night and never have anything less than full bars on my battery. I hadn't used my cell phone all day and in fact, I had pulled the phone off the charger at 2pm, so it's not like it wasn't plugged in all day (i.e. it was half dead at like 5pm - - only 3 hours after being completely charged). The only thing I could think of is, I wonder if it had anything to do with the crappy cell phone signal? Is it possible that since the cell phone wasn't getting a good singal, the cell phone had to work harder because it was constantly looking for a signal? That would explain why my battery was half dead and my moms was completely dead. I recharged my phone last night and it's been off the charger for almost 8 hours now and the battery is completely charged, so there's nothing wrong with my battery. ???????
