I made the mistake of getting a Panasonic cell phone with my AT&T service.
Phone has lousy audio, and now, to add insult to injury, the stupid battery
quit suddenly !!! This is the Lithium battery (Panasonic brand) that came with
the phone; it was recharged maybe 20 times total. It died suddenly and
completely from one hour to the next, without any warning: I shut the phone off
with a full  charge on the battery, an hour later the phone won't turn on at
all !!! Turns out the battery died and won't recharge any more !! That is
really nuts, can you imagine needing the stupid phone, like in an emergency,
only to realize the battery you knew to be full is dead and the phone is
useless, all of that with no warning whatsoever ?? Well, get a Panasonic cell
phone and you might just have that experience !
