I got a replacement phone. Mine was having heat issues. The replacement uses my same battery, and I have checked the same version of all the code. I have on it all the same apps. On the origional phone I was getting a decent usage on my battery, with it easily lasting 12+ hours, including my std usage for 1-2hours of that time. Now the battery never charges to full capacity and when I use an app like angry birds, and I can see it drain from 50% to under 15% in about 10 minutes. This effect is not consistant, so I am not sure what is going on. Any thoughts?
