How to better manage your phone
Yes turning off your gps, bluetooth, wifi and turning down the brightness of your screen are all great ideas to extend the battery life of your lg optimus slider phone. I used to have my screen at about 10 percent of brightness, then I got use to it and just turned it all the way down and I can see the screen just fine indoors. Also, leaving any web page open drastically drains the battery. You'll need to close all your windows that are open in the web browser you are using, so the page/s don't kill your battery. Another tip, turn your phone off to charge it. I went from a nearly dead battery to about 95 % charged in 20/30 mins, while charging my phone when it is turned off.
