Battery problem

[Dulanic]

Mine is completely random it seems. I wake up at 6AM and take my phone off my charger, I get home at about 5PM and on some days I'm at 80% other days 20%. Nothing changes in the way I use my phone, I don't make phone calls at work, the most I do is occasionally is check emails and that doesn't seem to make the difference.

I use X-Button and HTC Home Kaiser..... nothing beyond that really.
