Hey guys, I recently bought a rMBP 13" 2015 model and it's been going great...except for the battery. Just for the past hour all I've been doing is web browsing, checking a few emails, watched around 3 YouTube videos and went around Facebook. 25% of battery was drained. 25%. That's a lot for just 1 hour by doing some light work. The screen brightness was around 4 bars too. I know that Chrome is a battery hog and I still use it because I don't like Apple's built-in offering, but that's about it. That being said, this is my 3rd day using the rMBP and I've only charged it twice. I've heard from a post a very long time ago that battery life for the first few days are kinda crappy. Can anyone confirm this for me? Also what charging routine should I follow? The sales guy at the Apple Store said to fully drain the battery then charge it back up to 100%, should I continue this? Thanks guys, much appreciated.
