Nothing!
The battery life is sub-par for a phone with this many goodies. But that's something you have to live with unless you buy the extended battery.
This phone is awesome and the best I have ever owned. It has so many features I don't know where to begin.
First, the 1.3 mega-pixel camera is very good quality for a phone! I take pictures and put them on my computer. Also takes great, smooth video.
The MP3 player is so cool too. There is a memory card slot for mini-SD card. You can put pictures and music on there.
The speakers are stereo speakers and play very loud! It almost sounds like a mini boom box. This makes for awesome custom ring tones.
I have never used the blue-tooth wireless capabilities, but I'm sure that is super cool. They make many accessories for them such as a wireless head set.
The speakers on this phone blow very easily. I have had four refurbished models now and I'm still not happy.
