Xperia Z5 vs Galaxy S6 battery

[AC Question]

I am going to buy a new phone of contract in a few days. I have watched a lot of reviews and am now doubting between the Samsung Galaxy S6 and the Sony Xperia Z5. I know both pros and cons between the phones, but there remains 1 uncertainty: the battery. Some sites or reviews say that the Z5 has a better battery life, and some say the S6 has te better life. Why are there so many different views on something like battery life? And which one really has the better battery life, and how much hours of time?
Thanks,
Reno

Hello!! Welcome to Android Central!! Battery life is subjective because people use there phones very differently. People use different carriers which all have varying levels of service in any given location. And so on. I can't speak to the Z5, but I do have an S6. The battery life has been very erratic for me. I am a moderate user and I can make it through a full day of usage most days.
