I got at least 4.5 days of battery life this time. All sync deactivation was key. I had to charge it today at noon, the last time was Sunday at around noon.
If you go over your macro goal limit it gives a warning in your current food entry in myfitness pall, saying your supposed to hit 178 grams of protein or whatever. I think I will play with a function in myfitnesspal which subtracts from allotted calories if I'm lazy. You don't burn much calories when sedentary. Some users even keep their activity level at sedentary and the fitbit changes the amount of calories you need dynamically based on activity level.
