So after turning off "adjust automatically" about a week ago in the display settings I have noticed a huge battery improvement. My question is what is your brightness set at? 1/4, 1/2, 3/4, full? Just trying to see where most people are with there settings and how the battery has been with it. Right now I'm around 1/4 but wondering if anyone set on about 1/2 or more has noticed battery drainage. Also, will the 2.1 update fix the battery problem? Thanks.
