ok so iam kind of new to the G1.i seem to be having a problem.my battery life always goes so fast! i have dont things to try to save it like i turned my screen brightness to 0 my wifi is off i use 2g instead of 3g.i make sure i dont have so many things going at once and everything.So today i was on my phone just texting.first my battery life was 100 and about 20 mins latter it was 95% .that so annoying to me.so is there anything else i can do to save battery life or slow it down?Any good battery saver apps?Or should i just get a second battery?Thanks!
