6. Shut off gps if you arent using it...Especially if you are indoors alot..gps tends to loose signal easy and if it can't find it it will keep searching.
So, I was curious about these...
I turned off the S-Voice thing and the GPS last night and saw a HUGE improvement in my battery life. I was down to about 38% after about 20 hours. I was streaming music from Google Music for quite a while, and also used several other apps throughout the day along with a couple of phone calls.
Then, I charged it to 100% right before leaving work. It's now been 1:20, and I'm still at 98% having used a few times (not much action) since then.
