Just wait till it's in everyone's hands, and then wait another week or 2 for folks to use it like they NORMALLY would -
not like they do in the first day or 2. Seriously all, don't listen to any battery life reports of someone's first day of use. Also, as all the others have said, battery life will likely be somewhat different for everyone .
Many factors are part of battery life, the biggest of which, and also the things that tend to vary a lot are:
- How good of a network signal are you getting?
- How high is your screen brightness?
- How many, how often, and for how long are background updates running (along with specific bad apps eating battery in the background). ?
- What are you doing with your SoT? Is it hours of intense gaming or video chatting which will drain the battery quite heavily, or is it just web browsing, and texting, etc, which will be far less taxing?
The answers to those questions greatly impact one's battery life.
We'll know soon enough. But I am not going to pay attention to any of them until I get my Note 7 and compare it to my Note 5 under the same conditions - after a week or so.
