I had the zte X500 and I used juice defender. the multiplier indicated x1.60 and above all the time and battery could go for like 2 days without charging. However, on this phone it says x1.34 and I definetely miss the extremely long battery life. I am using the same apps as before. Nothing different. Is there any other battery saving app that can work just as good on this phone? I installed battery guru beta.
