I received this phone as a replacement for my Katana II after my earpiece broke. The guy at the sprint store raved about how great this phone was and how much better it was than the Katanas....what a liar! I've had this phone for nearly 3 weeks and I'm at my wits end with it. I charge my phone constantly and I still cannot have a conversation for more than 7 minutes without the phone dying. Unless I am plugged into the wall my phone constantly dies and it is sooo frustrating! Whenever I take the phone off the charger it always shows that it's a full charge so it's not that I'm not charging it long enough. I once left my phone plugged in for 16 hours (8 while I slept and 8 hours of work) and when I went to use it on a roadtrip (I had not used it all day) I didn't even get 3 minutes into the coversation and the battery died.

I received the phone on a Tuesday and that Friday I went back in and complained about my battery life, they had their techs run some tests on it and said that everything works fine. It's the worst phone I've ever had. I cannot even trust my battery to last in case of an emergency.

Also, it randomly shuts itself off. I'll be texting or talking (even while charging) and it will shut off without warning. The screen will flicker and it dies.

As for the other features: I've never used the MP3 player but I think that'd make it even worse on the battery life. The camera works ok....nothing spectacular. I'm purchasing a new phone soon because this is just too stressful and I would've been better off keeping my Katana II and using an earpiece than having this one. Please do not waste your money on this phone, it's not worth all the hassle. I hope this as been helpful!
