Sure the first Beta sucks but apple said at the keynote they are seeing +1 hour battery and +4 with energy saver on. Maybe they are already using a new build than us :/Interesting theory, but the sad truth is you can switch all the usual suspects of battery drain, i.e. background refresh, location, search settings for Proactive etc and even dim the display to near zero.... this first beta will still suck in battery life. I mean, it has made a complete muppet out of the normally-amazing iPhone 6+ battery
