I have the Galaxy s4 from Sprint and I was wondering what are your reviews on the 4.3 update and you u recommend me updating to 4.3. I am asking because my phone wants to update to 4.3 and I need to know if there are any issues after the update especially battery life, I get more than 12 hours on a single charge off and on wi-fi (which is excellent to me). I am thinking if I choose to update my phone to 4.3 the battery life would get worse. Can you please let me know about the battery life and if there are any issues you are having after the 4.3 update. I already know the Galaxy s4 from AT&T 4.3 update caused their phones to have wifi problems.
