Screen comes on automatically

[infinitemethod]

I've already had to replace my first Diamond because the front buttons were not working properly. I also noticed the first one would just turn the screen on randomly with no notifications. I've had my replacement for about 8 hours now and they both run on at the exact same times. My best guess is that it's going in and out of data area maybe? But I find that hard to believe because I'm in a good area, everything works extremely fast where I am.

I'm still new to Windows Mobile so maybe I have something setup wrong? I have my e-mail set to check manually and same with weather. You guys have any ideas? I'm sure this isn't helping my battery life either.....
