Here , I would like to say something about it.
Having got this phone more than a 3 months ago, I have to admit that it is the best phone that I've had. Maybe it's because of the technology nowadays, but either way, I love it, and I highly recommend it to anyone who is looking for a phone with a decent camera, music player, and overall quality.
Battery Life: When I first started using the phone, the battery life was amazing. I would play games and listen to music for hours and it would still have full battery after a long time. However, now that I've used it for over a month, the battery life is slowly but steadily dropping. I sometime charge my phone once every 2 days, which I didn't have to do when I first got the phone.
Contact List: The contact list is extremely well designed, compared to the other SE phones that I've had/used. It makes dialing easy, with easy navigating and a simple way of adding new contacts. All you have to do is find your contact, and press the right and left button to choose which phone number you'd like to dial. It's as simple as that!
Videos: This phone comes with a mp4 player, a video DJ, as well as a video recorder. I really didn't expect much from the mp4 player, since mp4s are never in good quality anyway, but compared to other mp4 players, the quality was pretty decent anyway.
So the coming problem is that I have to find a good mp4 converter to play videos on my phone, as i am one PC user ,so I found MP4 Converter for Windows , which converts MP4 to WMV/DivX, MP4 to MP3, AVI to MP4, MPEG to MP4, and WMV to MP4 video perfectly with personalized parameters settin ,and i got one trial edition at
MP4 Converter for Windows - Convert MP4 Video, AVI/MPEG to MP4/WMV Video Converter software, really very useful
The video DJ, to me, was pretty useless, since there really isn't any reason to make your own videos with a phone when you can use your computer, which doesn't take up as much time. But if you're just THAT bored, then the video DJ can cure some boredom. But otherwise, I found that it was a pretty useless feature.
As for the video recorder, I didn't expect much from it either. The sound was not that great, the quality was not that great, but for a video recorder on a phone, it was not great, but good.
So, overall, the Sony Ericsson w810i is a very good phone with many great features. It can be a little pricey, depending on where you're buying it. But trust me, all that money is worth it
