Update - Seidio 175 mAh Battery
OK, I received my Seidio battery and have only ran 2 charges through it but here is my experience so far...
With my normal usage I get approximately 1 1/2 days from the stock battery and it is DEAD.
I have the Seidio battery in now and I took it off the charger yesterday morning, it is now 11:00am here and my battery is at 66%.
I don't know about you but in my eyes that is a major improvement!
A note on the Seidio battery:
It is not the same battery as their Touch Pro 2 battery, it fits better. I used the touch Pro 2 battery in it for a day or 2 but regardless of what everybody is saying, the Touch Pro 2 battery doesn't fit right in my books.
Sure, it fits in the phone and you can put the battery door on it just fine but it is tight.
When you really notice it is taking the cover off with the Touch Pro 2 battery in the Incredible. It is hard to get the cover off. Maybe it's just me but I would rather spend the extra money on the right battery than have to replace the cover because the very fragile little tabs that hold it on have broken off from being over stressed.
Just my 2 cents worth, I'm sure the results will vary with other users.
I currently work out of my home and have a good strong wifi connection, the above test is with wifi on for the entire time, and Bluetooth off when not in use (not really sure if that matters yet). I only use bluetooth when I go some where in my truck so I had it on for about an hour yesterday.
