This is my third smartphone. I find that no matter what you do the standard battery is never adequate. I use my phone mainly for talk, email, text and web browsing only. I'm lucky to get 8 hours. I resigned to this issue, so I always buy an extended battery. I'm waiting for reviews on which extended battery to purchase. It's unfortunate that we have to do this.
If you uncheck that map will not work, FC for me when I try and open it. Plus I like google knowing where I am when I do a search, that is where ATK comes in handy. When I am done I close it and its not using any juice anymore.
Great news all!
I installed the leaked Froyo 2.2 and this bug does NOT exist.
I run the exact same test and my phone does indeed go to sleep after the GPS is activated.
Now I can leave my GPS always on again!
But when I went under privacy and unchecked the one sh6ne was talking about that said use my location, when I open maps it will FC. Then when I go back in and check it maps work fine.
