Wow. Battery is much better with auto-sync and data off.
Started the morning at 88% (not a full charge) that dropped to a 78% after one text.
Then did some angry birds and a few texts, and went to 75%, went out for three hours and when I was back my phone was at 74%, that's with a few more texts and facebook thrown in there too!
Then I did some browsing and FB checking while watching a movie (didn't turn data /auto sync off to test it..) and battery dropped to 55% after i finished the movie.
Did some texts and some more facebook, and I messed around with some settings... and now its at least fourteen hours later and my battery was at 43%.
Very, very impressed. Frenchy, instead of senior member, it should call you king of batteries.
Great tips, can't wait to see how they turn out over the next few days.
