My battery life seems to be going down hill the last week or so. I was getting 5 hours to 5.5 hours regularly. Now I'm right around 4 to 4.5. I had one day last week where I was really busy with work and had a lot of calls and I got 2.5 hours which I can't deal with. I ultimately sold my V10 because I would only get 3 to 3.5 hours. I don't know why but for what these phones cost I always have it in my head that I need at least 4.5 hours for me to stick with a phone.
