Had my phone for 27 hours now...
So I've had my Evo 3D since around 5pm CST yesterday and it's now pushing 8pm. I've had a full day to play with it so I'll give you all my thoughts. I had the Evo 4G and said goodbye to my beloved baby today and got $150 at the Sprint store for it (I didn't feel like fighting on Ebay to sell my phone).
First off...this phone is amazing. It seems that it is an Evo 4G with the kinks worked out. That's all I wanted out of it plus a few perks. The phone is zippy, I have put on all of the apps I had on my Evo and don't have the message nagging me that the phone is running low on memory.
I took my phone off of the charger at 4:30 this morning (took my parents to the Airport) and have put it on the charger for a total of about 30 minutes since then and the phone went into the yellow battery zone about 30 minutes ago. I was used to my 3500 mAh battery, so it's hard for me to compare. But I will say that the battery life is sufficient. I think I'll be moving to the 1900mAh battery when it comes out, but I don't want to thicken the phone like I had done with my Evo. I am typically around a charger at all times so I really don't need a thick battery. This may be an issue for people who can't get to a charger as often, but it works for me.
I compared some things to my Evo before I got rid of it and it's obvious how much faster this phone is. I opened up Angry Birds Rio and was playing the game while my Evo still was loading it up. I noticed loading up video seemed to be slower, but it wasn't slow to the point of being an irritation. However, I'm in the honeymoon phase with the phone so I might be letting things slide because of that.
One of the complaints I read/saw in official reviews from multiple websites talked about how sensitive the power button is. I assure you, that is not the case at all. I saw a video where a finger was being run across the top and that engaged the power button, but that is not the case with my phone at all. So a sensitive power button is definitely not the issue for me.
Signal wise, I don't notice any more fluctuations with the signal than I did with my original Evo or the other 3 phones on my account. I was actually surprised that I drove in an area that my Evo ALWAYS dropped calls (I mean 100% of the time I drove through this particular area, the call dropped) and the Evo 3D held onto the call. I also noticed that my Evo 4G would drop calls when I would leave my house (where it was connected to the Airave). The Evo 3D is handling the calls the proper way and simply handing the call off to the Sprint towers. There isn't any 4G connectivity in my city (Milwaukee) so I can't test that.
As far as 3D pictures, they hurt my eyes when I take the picture in semi low light settings. When I took 3D pictures with my dog outside earlier today, the pictures were great and didn't make my eyes hurt. The 3D video is pretty amazing. I was watching The Green Hornet and was impressed at how the video was showing up. I hope Youtube works out a 3D button for the app, but until then, I know how to identify the 3D videos within the app (hint: it has 3D next to the title of the video. If the video doesn't appear in 3D, do a battery pull and it will work just fine).
That's enough ranting for me for a while. If you have any questions, shoot.
