I bought my first smart phone 3 days ago, the droid 2 global, and am very impressed with it! I am just confused about how to manage application to maximize battery life. I am running the juice defender app and advanced task killer to try to increase battery life. I charge it over night then i have to charge again around 3pm every day so far. I have been using the phone heavily (games, apps, and internet) since i got it, but the battery life is still the only negative aspect of the phone. If I open any application, lets say the browser, and while I am surfing the internet decide to make a phone call. I hit the home button and proceed to make the call. I know the browser keeps running in the background on the last page I was viewing. After the phone call has ended, I forget about the web page I was looking at. The browser continues to run in the background, but will the operating system automatically put the browser "to sleep" or do I have to open the advanced task killer and manually kill the browser?
