So these batteries finally showed up yesterday. Took about 8 days.....not to bad I guess considering CA to OH shipping and the holidays.
Put one in the phone and it was at ~60% battery life. Did some internet surfing, facebooking, a few texts and a phone call. The battery went down to ~20% in about 3 hours. Not impressed so far.
Turned the phone off and plugged it in for the night.
As of this message, I've had it unplugged for almost 3 hours. Email is on automatic update and I've done a little google talk. I'm currently sitting at 92% battery life. With the standard battery, I'm usually sitting at 90% by the time I get to work, which was 2 hours ago.
So I'm happy so far....we'll see what happens as the day progresses. If I can go a full day without having to plug in the phone, this will be money well spent!
On a bad note, they did ship me the wrong wall charger. So I need to contact HTCexpress.com about that.
