Hi, I've just acquired a MBPr directly from the Apple store 2 days ago but I've noticed the battery was draining pretty fast. I was wondering if this was normal in the first few usage of the computer. Here are some examples From 100% to 90% in just over 30 minutes From 85% to 80% in under 10 minutes From 80% to 71% in 9 hours in sleep mode All of that with only chrome opened with two tabs, except from sleep mode I had exited all applications. I've now uninstalled chrome and went back to safari as I heard chrome is a killer. The only other app that could be causing a problem is my VPN, PrivateInternetAccess, which I also quit to see if it was source of the problem. Here are two screen shots of the activity monitor as of yesterday and a few minutes ago As of right now, it's 10:03 and 62% with 9:37 remaining. p.s. I'm concerned because I have very bad luck with laptop. My first Yoga had a defective battery (wouldn't hold 2-3 hours), had to send back, no more in stock so I got a Samsung Series 9 which I received with a broken keyboard, had to send back to get a replacement. I'm also very concerned because I leave out of the country Monday for 6 months, so I really hope nothing is wrong! ---------- It's now 10:06 with 61% and 9:07 remaining.
