Shopping for a new cell phone and I want a good battery and good bluetooth reception?

What specs do I look for, such as what kind of battery or bluetooth specs when shopping for a phone. I haven't had any luck with Samsung batteries and if I don't have the phone in my hand the bluetooth is all static. I'm going to shop around at AT%26amp;T and Verizon. Any suggestions?|||I currently have a contract with Tmobile.. THey have a good phone which is the samsung behold. Right now if you order this phone you will get a bluetooth headset for free. T-Mobile has great coverage I will give them a try.|||I just bought a LG Keybo also known as the ENV2 . It lasted me 5 days before i had to recharge the battery.. it also has blue tooth! and it folds open to be a full keyboard.. which is awesome for texting! :)|||get the touch pro for sprint. very nice.. battery last about 9 hour talk time.
